        You are  cautioned  not to  place  undue  reliance  on  forward-looking
statements,  as  there  can be no  assurance  that  the  plans,  intentions  or
expectations   upon  which  they  are  based  will  occur.   By  their  nature,
forward-looking  statements  involve  numerous  assumptions,  known and unknown
risks and  uncertainties,  both general and  specific,  that  contribute to the
possibility  that the  predictions,  forecasts,  projections  and other  things


                                       4


contemplated  by the  forward-looking  statements  will not occur.  Although we
believe that the expectations  represented by such  forward-looking  statements
are reasonable,  there can be no assurance that such expectations will prove to
be correct.  Some of the risks and other  factors  which could cause results to
differ  materially  from  those  expressed  in the  forward-looking  statements
contained in this prospectus and the documents incorporated by reference herein
include,  but are not limited to:  volatility of and assumptions  regarding oil
and  natural  gas  prices,   assumptions   based  upon  our  current  guidance,
fluctuations in currency and interest rates, product supply and demand,  market
competition,  risks  inherent in our North American and foreign oil and natural
gas and midstream operations, risks of war, hostilities, civil insurrection and
instability  affecting  countries in which we and our subsidiaries  operate and
terrorist  threats,  risks  inherent  in our  and our  subsidiaries'  marketing
operations,  including  credit  risk,  imprecision  of reserves  estimates  and
estimates  of  recoverable  quantities  of oil,  natural gas and  liquids  from
resource plays and other sources not currently  classified as proved  reserves,
our and our  subsidiaries'  ability to replace  and expand oil and  natural gas
reserves, risks associated with technology,  our ability to generate sufficient
cash flow from  operations  to meet our  current  and future  obligations,  our
ability to access external sources of debt and equity capital, general economic
and business conditions,  our ability to enter into or renew leases, the timing
and costs of gas storage facility, well and pipeline construction,  our ability
to make capital investments and the amounts of capital investments, imprecision
in  estimating  the timing,  costs and levels of production  and drilling,  the
results of exploration,  development and drilling,  imprecision in estimates of
future  production  capacity,  our  and our  subsidiaries'  ability  to  secure
adequate  product  transportation,  uncertainty  in the  amounts  of  timing of
royalty  payments,  imprecision  in  estimates  of  product  sales,  changes in
environmental and other regulations or the  interpretation of such regulations,
risks  associated  with existing and potential  future  lawsuits and regulatory
actions against us and our subsidiaries,  political and economic  conditions in
the countries in which we and our subsidiaries operate, difficulty in obtaining
necessary regulatory approvals and such other risks and uncertainties described
from time to time in our  reports  and  filings  with the  Canadian  securities
authorities  and the SEC.  Statements  relating to "reserves"  are deemed to be
forward-looking  statements,  as they involve the implied assessment,  based on
certain  estimates and  assumptions,  that the reserves  described exist in the
quantities  predicted  or  estimated,  and can be  profitably  produced  in the
future.

        We  caution  that  the  foregoing  list  of  important  factors  is not
exhaustive.  Events or  circumstances  could cause our actual results to differ
materially  from those  estimated or projected and expressed in, or implied by,

                               ENCANA CORPORATION

        We are one of North America's leading natural gas producers,  are among
the largest holders of natural gas and oil resource lands onshore North America
and are a  technical  and cost  leader  in the  in-situ  recovery  of  oilsands
bitumen.  We pursue  growth from our  portfolio  of  long-life  resource  plays
situated  in  Canada  and  the  United  States.   Contained  in  unconventional
reservoirs,  resource plays are large contiguous accumulations of hydrocarbons,
located in thick or a really  extensive  deposits,  that  typically  have lower
geological and commercial  development  risk, lower average  long-term  decline
rates and very long producing lives compared to conventional plays. We are also
engaged in select exploration and production activities internationally.

        We continually pursue opportunities to develop and expand our business,
which may include significant  corporate or asset acquisitions.  We may finance
such acquisitions with debt or equity, or a combination of both.

        Our principal executive and registered offices are located at 1800, 855
- 2nd Street S.W., Calgary, Alberta T2P 2S5, Canada.

                                USE OF PROCEEDS

        Unless  otherwise  indicated in the  applicable  prospectus  supplement
relating  to a  series  of debt  securities,  we will use the net  proceeds  we
receive from the sale of the debt  securities for general  corporate  purposes.
Those  general  corporate  purposes  may  include  capital  expenditures,   the
repayment of indebtedness and the financing of acquisitions.  The amount of net
proceeds to be used for any such purpose  will be  described  in an  applicable
prospectus  supplement.  We may invest funds that we do not  immediately use in
short-term marketable securities.

                         DESCRIPTION OF DEBT SECURITIES

        In this  section  only,  "we",  "us",  "our" or "EnCana"  refer only to
EnCana  Corporation  without any of its  subsidiaries or  partnerships  through
which it operates.  The following  description  describes certain general terms
and provisions of the debt securities. We will provide the particular terms and
provisions of a series of debt  securities and a description of how the general
terms and provisions  described  below may apply to that series in a supplement
to this prospectus.

        The debt  securities  will be issued  under an  indenture  (hereinafter
referred to as the  "Indenture")  to be entered into between us and The Bank of
New York,  as "Trustee".  The Indenture  will be subject to and governed by the
U.S. Trust Indenture Act of 1939, as amended. The following is a summary of the
Indenture  which  describes  certain  general terms and  provisions of the debt
securities and is not intended to be complete;  these  statements are qualified
in their  entirety  by,  and  subject  to,  the  provisions  of the  Indenture,
including the definition of capitalized terms used under this caption.  We urge
you to read the Indenture carefully,  because it is the Indenture, and not this
summary,  that  governs  your  rights as a holder of our debt  securities.  See
"Where You Can Find More Information" in this prospectus. Prospective investors
should rely on information in the applicable prospectus  supplement,  which may
provide information that is different from this prospectus.

        We may, from time to time,  issue debt instruments and incur additional
indebtedness  other than  through the issuance of debt  securities  pursuant to
this prospectus.

GENERAL

        The  Indenture  does not limit the aggregate  principal  amount of debt
securities (which may include  debentures,  notes and other unsecured evidences
of indebtedness)  that we may issue under the Indenture.  It provides that debt
securities  may be issued  from time to time in one or more  series  and may be
denominated  and  payable in U.S.  dollars  or any  foreign  currency.  Special
Canadian and U.S.  federal income tax  considerations  applicable to any of our
debt  securities  denominated  in a foreign  currency  will be described in the
prospectus  supplement relating to any offering of debt securities  denominated
in a foreign currency.  The debt securities offered pursuant to this prospectus


                                       6


will be issued in an aggregate principal amount of up to  US$2,000,000,000,  or
if any debt  securities  are offered at original issue  discount,  such greater
amount   as  shall   result   in  an   aggregate   offering   price  of  up  to
US$2,000,000,000,  or the  equivalent in other  currencies.  The Indenture also
permits  us to  increase  the  principal  amount  of any  series  of  our  debt
securities  previously issued and to issue that increased principal amount. The
applicable prospectus supplement will set forth the following terms relating to
the debt securities being offered by us:

        o       the specific  designation and the aggregate principal amount of
                the debt securities of such series;

        o       the  extent  and  manner,  if any,  to which  payment  on or in
                respect of our debt securities of such series will be senior or
                will  be  subordinated  to  the  prior  payment  of  our  other
                liabilities and obligations;

        o       the percentage or percentages of principal  amount at which our
                debt securities of such series will be issued;

        o       the date or dates on which the  principal of (and  premium,  if
                any, on) our debt securities of such series will be payable and
                the  portion  (if less than the  principal  amount) of the debt
                securities of such series to be payable upon a  declaration  of
                acceleration  of maturity  and/or the method by which such date
                or dates shall be determined or extended;

        o       the rate or rates (whether fixed or variable) at which our debt
                securities of such series will bear  interest,  if any, and the
                date or dates from which such interest will accrue;

        o       the dates on which any interest will be payable and the regular
                record dates for the payment of interest on our debt securities
                of such series in registered form;

        o       the place or places  where the  principal of (and  premium,  if
                any,  and  interest,  if any, on) our debt  securities  will be
                payable, and each office or agency where our debt securities of
                such series may be presented  for  registration  of transfer or
                exchange;

        o       if other  than U.S.  dollars,  the  currency  in which our debt
                securities of such series are  denominated or in which currency
                payment of the principal of (and premium, if any, and interest,
                if  any,  on)  such  debt  securities  of such  series  will be
                payable;

        o       whether our debt  securities of such series will be issuable in
                the  form of one or more  global  securities  and,  if so,  the
                identity of the depositary for the global securities;

        o       any   mandatory   or  optional   redemption   or  sinking  fund
                provisions;

        o       the  period or  periods,  if any,  within  which,  the price or
                prices  at  which,  the  currency  in which  and the  terms and
                conditions upon which our debt securities of such series may be
                redeemed or purchased by us;

        o       the terms and conditions, if any, upon which you may redeem our
                debt  securities of such series prior to maturity and the price
                or  prices  at  which  and  the  currency  in  which  our  debt
                securities of such series are payable;

        o       any index used to determine the amount of payments of principal
                of (and  premium,  if any, or  interest,  if any,  on) our debt
                securities of such series;

        o       the  terms,  if  any,  on  which  our  debt  securities  may be
                converted or exchanged for other of our debt securities or debt
                securities of other entities;

        o       any  other  terms  of  our  debt  securities  of  such  series,
                including covenants and events of default which apply solely to
                a particular  series of our debt securities being offered which
                do  not  apply  generally  to  other  debt  securities,  or any
                covenants or events of default generally applicable to our debt
                securities  of such series  which do not apply to a  particular
                series of our debt securities;


                                       7


        o       if  other  than  The  Depository  Trust  Company,   the  person
                designated as the  depositary  for the debt  securities of such
                series;

        o       any applicable  material  Canadian and U.S.  federal income tax
                consequences;

        o       whether  and under what  circumstances  we will pay  Additional
                Amounts  (defined below under "Payment of Additional  Amounts")
                on the debt  securities  of such  series in  respect of certain
                taxes (and the terms of any such payment)  and, if so,  whether
                we will have the option to redeem the debt  securities  of such
                series rather than pay the Additional Amounts (and the terms of
                any such option);

        o       whether the payment of our debt  securities  will be guaranteed
                by any other person;

        o       whether the series of our debt  securities are to be registered
                securities,  bearer  securities  (with or without  coupons)  or
                both; and

        o       if  other  than  denominations  of  US$1,000  and any  integral
                multiple  thereof,  the  denominations  in which any registered
                securities  of the series shall be issuable  and, if other than
                the denomination of US$5,000, the denomination or denominations
                in which any bearer securities of the series shall be issuable.

        Unless otherwise indicated in the applicable prospectus supplement, the
Indenture  does not afford  holders of our debt  securities the right to tender
such debt securities to us in the event that we have a change in control.

        Our debt  securities  may be issued  under  the  Indenture  bearing  no
interest or at a discount below their stated principal amount. The Canadian and
U.S.  federal  income  tax   consequences  and  other  special   considerations
applicable to any such  discounted  debt  securities  or other debt  securities
offered  and sold at par which are  treated as having been issued at a discount
for Canadian  and/or U.S.  federal income tax purposes will be described in the
prospectus supplement relating to the debt securities.

RANKING

        Unless otherwise indicated in an applicable prospectus supplement,  the
debt securities will be unsecured and unsubordinated  obligations and will rank
equally  with  all of  our  other  unsecured  and  unsubordinated  indebtedness
outstanding from time to time. We conduct a substantial portion of our business
through  corporate and  partnership  subsidiaries.  The debt securities will be
structurally   subordinated  to  all  existing  and  future   indebtedness  and
liabilities,  including trade payables,  of any of our corporate or partnership
subsidiaries.

DEBT SECURITIES IN GLOBAL FORM

THE DEPOSITARY, BOOK-ENTRY AND SETTLEMENT

        A series  of our debt  securities  may be issued in whole or in part in
global form as a "global security" and will be registered in the name of and be
deposited with a depositary,  or its nominee,  each of which will be identified
in the  prospectus  supplement  relating  to  that  series.  Unless  and  until
exchanged,  in  whole  or in  part,  for  our  debt  securities  in  definitive
registered form, a global security may not be transferred  except as a whole by
the depositary for such global  security to a nominee of the  depositary,  by a
nominee  of  the  depositary  to  the  depositary  or  another  nominee  of the
depositary  or by the  depositary  or any such  nominee to a  successor  of the
depositary or a nominee of the successor.

        The specific  terms of the depositary  arrangement  with respect to any
portion of a particular  series of our debt  securities to be  represented by a
global security will be described in a prospectus  supplement  relating to such
series.  We  anticipate  that  the  following  provisions  will  apply  to  all
depositary arrangements.

        Upon the issuance of a global security,  the depositary therefor or its
nominee will credit, on its book entry and registration  system, the respective
principal amounts of our debt securities  represented by the global security to
the accounts of such persons,  designated as  "participants",  having  accounts
with such  depositary or its nominee.  Such accounts shall be designated by the
underwriters,  dealers or agents  participating in the distribution of our debt


                                       8


securities  or by us if such debt  securities  are offered and sold directly by
us.  Ownership of beneficial  interests in a global security will be limited to
participants   or  persons   that  may  hold   beneficial   interests   through
participants.  Ownership of beneficial  interests in a global  security will be
shown on, and the transfer of that  ownership  will be effected  only  through,
records  maintained by the depositary  therefor or its nominee (with respect to
interests  of  participants)  or by  participants  or persons that hold through
participants  (with respect to interests of persons  other than  participants).
The  laws  of some  states  in the  United  States  may  require  that  certain
purchasers  of securities  have the ability to take  physical  delivery of such
securities in definitive form.

        So long as the depositary for a global security, or its nominee, is the
registered  owner of the global security,  such depositary or such nominee,  as
the case  may be,  will be  considered  the sole  owner or  holder  of the debt
securities  represented  by the  global  security  for all  purposes  under the
Indenture. Except as provided below, owners of beneficial interests in a global
security  will  not be  entitled  to  have a  series  of  our  debt  securities
represented by the global security  registered in their names, will not receive
or be  entitled  to  receive  physical  delivery  of such  series  of our  debt
securities in definitive  form and will not be considered the owners or holders
thereof under the Indenture.


        PAYMENTS OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST

        Any  payments of  principal,  premium,  if any,  and interest on global
securities  registered  in the name of a depositary or its nominee will be made
to the depositary or its nominee,  as the case may be, as the registered  owner
of the  global  security  representing  such debt  securities.  None of us, the
Trustee or any paying agent for our debt  securities  represented by the global
securities  will have any  responsibility  or  liability  for any aspect of the
records  relating  to or  payments  made on  account  of  beneficial  ownership
interests of the global security or for  maintaining,  supervising or reviewing
any records relating to such beneficial ownership interests.

        We expect that the  depositary  for a global  security or its  nominee,
upon receipt of any payment of principal,  premium,  if any, or interest,  will
credit participants'  accounts with payments in amounts  proportionate to their
respective  beneficial interests in the principal amount of the global security
as shown on the records of such depositary or its nominee.  We also expect that
payments by participants to owners of beneficial interests in a global security
held through such  participants  will be governed by standing  instructions and
customary  practices,  as is now the case with securities held for the accounts
of customers  registered in "street name",  and will be the  responsibility  of
such participants.


        DISCONTINUANCE OF DEPOSITARY'S SERVICES

        If a depositary for a global security  representing a particular series
of our debt  securities  is at any time  unwilling  or  unable to  continue  as
depositary and a successor depositary is not appointed by us within 90 days, we
will issue such series of our debt  securities in  definitive  form in exchange
for a global  security  representing  such  series of our debt  securities.  In
addition, we may at any time and in our sole discretion determine not to have a
series of our debt  securities  represented  by a global  security and, in such
event,  will  issue a  series  of our debt  securities  in  definitive  form in
exchange  for all of the  global  securities  representing  the  series of debt
securities.

DEBT SECURITIES IN DEFINITIVE FORM

        A series  of our debt  securities  may be issued  solely as  registered
securities,  solely as bearer  securities or as both registered  securities and
bearer securities.  Registered  securities will be issuable in denominations of
US$1,000 and  integral  multiples  of US$1,000  and bearer  securities  will be
issuable  in  denominations  of  US$5,000  or,  in each  case,  in  such  other
denominations  as may be set out in the  terms  of the debt  securities  of any
particular  series.  Unless  otherwise  indicated in the applicable  prospectus
supplement, bearer securities will have interest coupons attached.

        A prospectus  supplement may indicate the places to register a transfer
of our debt  securities.  Except  for  certain  restrictions  set  forth in the
Indenture,  no service charge will be made for any  registration of transfer or
exchange of our debt securities,  but we may, in certain  instances,  require a
sum  sufficient  to cover  any tax or other  governmental  charges  payable  in
connection with these transactions.


                                       9


        We shall not be required to:

        o       issue,  register  the transfer of or exchange any series of our
                debt  securities  during a period  beginning  at the opening of
                business  15 days  before any  selection  of that series of our
                debt  securities  to be  redeemed  and  ending  at the close of
                business  on (i) if the  series  of  our  debt  securities  are
                issuable only as registered  securities,  the day of mailing of
                the relevant notice of redemption and (ii) if the series of our
                debt securities are issuable as bearer  securities,  the day of
                the first  publication of the relevant notice of redemption or,
                if the  series  of our debt  securities  are also  issuable  as
                registered securities and there is no publication,  the mailing
                of the relevant notice of redemption;

        o       register the transfer of or exchange any  registered  security,
                or  portion   thereof,   called  for  redemption,   except  the
                unredeemed portion of any registered security being redeemed in
                part;

        o       exchange any bearer security  selected for  redemption,  except
                that,  to the  extent  provided  with  respect  to such  bearer
                security,   such  bearer   security  may  be  exchanged  for  a
                registered  security of that  series and like  tenor,  PROVIDED
                that such registered security shall be immediately  surrendered
                for redemption with written  instruction for payment consistent
                with the provisions of the Indenture; or

        o       issue,  register  the  transfer of or exchange  any of our debt
                securities  which have been  surrendered  for  repayment at the
                option of the holder,  except the portion,  if any, thereof not
                to be so repaid.

        Unless  otherwise  indicated in the applicable  prospectus  supplement,
payment  of any  interest  will be made to the  persons  in whose name our debt
securities are registered at the close of business on the day or days specified
by us.

CERTAIN DEFINITIONS

        Set forth  below is a summary of certain of the  defined  terms used in
the Indenture. We urge you to read the Indenture for the full definition of all
such terms.

        "CONSOLIDATED  NET TANGIBLE ASSETS" means the total amount of assets of
any person on a consolidated basis (less applicable reserves and other properly

COVENANTS

LIMITATION ON LIENS

        The Indenture  provides that so long as any of our debt  securities are
outstanding  and subject to the provisions of the  Indenture,  we will not, and
will not permit any of our Restricted Subsidiaries to, create, incur, assume or
otherwise  have  outstanding  any Lien securing any  indebtedness  for borrowed
money  or  interest  thereon  (or any  liability  of  ours  or such  Restricted
Subsidiaries under any guarantee or endorsement or other instrument under which
we or such Restricted  Subsidiaries are contingently liable, either directly or
indirectly,  for  borrowed  money or interest  thereon),  other than  Permitted
Liens,  without also simultaneously or prior thereto securing,  or causing such
Restricted Subsidiaries to secure, indebtedness under the Indenture so that our
debt  securities  are secured  equally and ratably  with or prior to such other
indebtedness,  except that we and our Restricted  Subsidiaries may incur a Lien
to secure  indebtedness for borrowed money without securing our debt securities
if, after giving effect  thereto,  the  principal  amount of  indebtedness  for
borrowed money secured by Liens created,  incurred or assumed after the date of
the Indenture and otherwise  prohibited by the Indenture does not exceed 10% of
our Consolidated Net Tangible Assets.

        Notwithstanding the foregoing, transactions such as the sale (including
any  forward  sale)  or  other  transfer  of (i) oil,  gas,  minerals  or other
resources of a primary nature,  whether in place or when produced, for a period
of time until, or in an amount such that, the purchaser will realize  therefrom
a specified amount of money or a specified rate of return (however determined),
or a specified  amount of such oil,  gas,  minerals,  or other  resources  of a
primary  nature,  or (ii) any  other  interest  in  property  of the  character
commonly referred to as a "production payment",  will not constitute a Lien and
will not result in us or a  Restricted  Subsidiary  of ours being  required  to
secure the debt securities.

CONSOLIDATION, AMALGAMATION, MERGER AND SALE OF ASSETS

        We may not  consolidate or amalgamate  with or merge into or enter into
any statutory  arrangement with any other corporation,  or convey,  transfer or
lease all or substantially all our properties and assets to any person, unless:

        o       the entity formed by or continuing from such  consolidation  or
                amalgamation or into which we are merged or with which we enter
                into such statutory arrangement or the person which acquires or
                leases all or substantially all of our properties and assets is
                organized and existing under the laws of the United States, any
                state thereof or the District of Columbia or the laws of Canada
                or  any   province   or   territory   thereof,   or,   if  such
                consolidation,  amalgamation,  merger, statutory arrangement or
                other transaction would not impair the rights of the holders of
                our debt  securities,  in any other  country,  PROVIDED that if
                such  successor  entity  is  organized  under  the  laws  of  a
                jurisdiction other than the United States, any state thereof or
                the District of Columbia, or the laws of Canada or any province
                or  territory   thereof,   the  successor  entity  assumes  our
                obligations  under the debt securities and the Indenture to pay
                Additional   Amounts,   with   the   name  of  such   successor
                jurisdiction being included in addition to Canada in each place
                that  Canada  appears  in "--  Payment of  Additional  Amounts"
                below;

        o       the successor entity expressly  assumes or assumes by operation
                of law all of our  obligations  under our debt  securities  and
                under the Indenture;

        o       immediately before and after giving effect to such transaction,
                no event of default,  and no event which, after notice or lapse
                of time or both,  would become an event of default,  shall have
                happened and be continuing; and

        o       certain other conditions are met.

        If, as a result of any such  transaction,  any of our or our Restricted
Subsidiaries' Restricted Properties become subject to a Lien, then, unless such
Lien could be created pursuant to the Indenture  provisions described under the
"LIMITATION ON LIENS" covenant above without  equally and ratably  securing our
debt securities,  we,  simultaneously  with or prior to such transaction,  will
secure,  or cause the  applicable  Restricted  Subsidiary  to secure,  our debt
securities to be secured equally and ratably with or prior to the  indebtedness
secured by such Lien.


                                      14


PAYMENT OF ADDITIONAL AMOUNTS

        Unless otherwise specified in the applicable prospectus supplement, all
payments  made by or on behalf of us under or with respect to any series of our
debt  securities  will be made free and  clear of and  without  withholding  or
deduction for or on account of any present or future tax, duty,  levy,  impost,
assessment or other  governmental  charge  (including  penalties,  interest and
other  liabilities  related  thereto)  imposed or levied by or on behalf of the
Government  of Canada or any province or territory  thereof or by any authority
or  agency  therein  or  thereof  having  power to tax  (hereinafter  "Canadian
Taxes"),  unless we are required to withhold or deduct Canadian Taxes by law or
by the  interpretation  or  administration  thereof.  If we are so  required to
withhold  or deduct any amount  for or on  account of  Canadian  Taxes from any
payment made under or with respect to the debt securities,  we will pay to each
holder of such debt securities as additional  interest such additional  amounts
("Additional  Amounts") as may be necessary so that the net amount  received by
each such holder after such  withholding or deduction (and after  deducting any
Canadian  Taxes on such  Additional  Amounts)  will not be less than the amount
such holder would have received if such Canadian Taxes had not been withheld or
deducted.  However,  no  Additional  Amounts  will be payable with respect to a
payment made to a debt securities holder (such holder, an "Excluded Holder") in
respect of the beneficial owner thereof:

        o       with which we do not deal at arm's  length (for the purposes of
                the Income Tax Act  (Canada)) at the time of the making of such
                payment;

        o       which is subject to such  Canadian  Taxes by reason of the debt
                securities holder being a resident, domicile or national of, or
                engaged in business or maintaining a permanent establishment or
                other physical  presence in or otherwise having some connection
                with Canada or any province or territory thereof otherwise than
                by the mere  holding of the debt  securities  or the receipt of
                payments thereunder; or

        o       which is subject to such  Canadian  Taxes by reason of the debt
                securities  holder's failure to comply with any  certification,
                identification,  documentation or other reporting  requirements
                if  compliance is required by law,  regulation,  administrative
                practice or an applicable treaty as a precondition to exemption
                from,  or a reduction in the rate of  deduction or  withholding
                of, such Canadian Taxes.

        We will also:

        o       make such withholding or deduction; and

        o       remit the full amount  deducted  or  withheld  to the  relevant
                authority in accordance with applicable law.

        We will furnish to the holders of the debt  securities,  within 60 days
after the date the payment of any Canadian  Taxes is due pursuant to applicable
law,  certified  copies of tax  receipts  or other  documents  evidencing  such
payment by us.

        We will  indemnify  and hold  harmless  each holder of debt  securities
(other than an Excluded  Holder) and upon written  request  reimburse each such
holder for the amount  (excluding any Additional  Amounts that have  previously
been paid by us with respect thereto) of:

        o       the payment of any Canadian  Tax,  together  with any interest,
                penalties and reasonable expenses in connection therewith; and

        o       any Canadian  Taxes  imposed with respect to any  reimbursement
                under the  preceding  clause,  but  excluding any such Canadian
                Taxes on such holder's net income.

        In any event,  no  Additional  Amounts  or  indemnity  amounts  will be
payable in excess of Additional Amounts or the indemnity amounts which would be
required if the holder of debt  securities  was a resident of the United States
for purposes of the Canada-U.S. Income Tax Convention (1980), as amended.

        Wherever in the  Indenture  there is  mentioned,  in any  context,  the
payment of principal  (and  premium,  if any),  interest,  if any, or any other
amount payable under or with respect to a debt security,  such mention shall be


                                      15


deemed to include  mention of the payment of  Additional  Amounts to the extent
that,  in such  context,  Additional  Amounts are,  were or would be payable in
respect thereof.

TAX REDEMPTION

        Unless otherwise specified in the applicable prospectus  supplement,  a
series of our debt  securities  will be subject to  redemption  at any time, in
whole but not in part,  at a  redemption  price equal to the  principal  amount
thereof  together  with  accrued  and  unpaid  interest  to the date  fixed for
redemption, upon the giving of a notice as described below, if:

        o       as a result of any change in or  amendment  to the laws (or any
                regulations or rulings promulgated  thereunder) of Canada or of
                any  political  subdivision  or  taxing  authority  thereof  or
                therein affecting taxation,  or any change in official position
                regarding  the  application  or  interpretation  of such  laws,
                regulations  or  rulings  (including  a  holding  by a court of
                competent jurisdiction), which change or amendment is announced
                or  becomes  effective  on or after the date  specified  in the
                applicable  prospectus  supplement,  we  have  or  will  become
                obligated to pay, on the next succeeding date on which interest
                is due, Additional Amounts with respect to any debt security of
                such  series as  described  under  "--  Payment  of  Additional
                Amounts"; or

        o       on or after the date  specified  in the  applicable  prospectus
                supplement,  any action has been taken by any taxing  authority
                of, or any decision  has been  rendered by a court of competent
                jurisdiction in Canada, or any political  subdivision or taxing
                authority  thereof or therein,  including  any of those actions
                specified in the paragraph  immediately  above,  whether or not
                such action was taken or decision was rendered  with respect to
                us, or any change,  amendment,  application  or  interpretation
                shall be officially  proposed,  which, in any such case, in the
                written opinion to us of legal counsel of recognized  standing,
                will  result  in our  becoming  obligated  to pay,  on the next
                succeeding  date on which interest is due,  Additional  Amounts
                with respect to any debt security of such series ;

and,  in any such  case,  we, in our  business  judgment,  determine  that such
obligation cannot be avoided by the use of reasonable measures available to us.

        In the event  that we elect to  redeem a series of our debt  securities
pursuant  to the  provisions  set forth in the  preceding  paragraph,  we shall
deliver to the Trustee a certificate,  signed by an authorized officer, stating
that we are entitled to redeem such series of our debt  securities  pursuant to
their terms.

        Notice of intention to redeem such series of our debt  securities  will
be given  not more than 60 nor less  than 30 days  prior to the date  fixed for
redemption and will specify the date fixed for redemption.

PROVISION OF FINANCIAL INFORMATION

        We will file with the  Trustee,  within 15 days after we file them with
the SEC, copies, which may be in electronic format, of our annual report and of
the information, documents and other reports (or copies of such portions of any
of the foregoing as the SEC may by rules and  regulations  prescribe)  which we
are  required  to file  with the SEC  pursuant  to  Section  13 or 15(d) of the
Exchange Act.

        Notwithstanding  that we may not be required  to remain  subject to the
reporting  requirements of Section 13 or 15(d) of the Exchange Act or otherwise
report on an annual and quarterly  basis on forms  provided for such annual and
quarterly  reporting pursuant to rules and regulations  promulgated by the SEC,
we will continue to provide the Trustee:

        o       within  140  days  after  the  end of  each  fiscal  year,  the
                information  required to be contained in annual reports on Form
                20-F,  Form 40-F or Form 10-K as  applicable  (or any successor
                form); and

        o       within 65 days after the end of each of the first three  fiscal
                quarters of each fiscal year,  the  information  required to be
                contained in reports on Form 6-K (or any successor form) which,
                regardless  of  applicable  requirements  shall,  at a minimum,
                contain such  information  required to be provided in quarterly


                                      16


                reports  under the laws of Canada or any  province  thereof  to
                security holders of a corporation with securities listed on the
                Toronto  Stock  Exchange,  whether  or not we  have  any of our
                securities  listed on such exchange.  Such  information will be
                prepared in accordance  with Canadian  disclosure  requirements
                and GAAP; PROVIDED,  HOWEVER, that we shall not be obligated to
                file such  report  with the SEC if the SEC does not permit such
                filings.

EVENTS OF DEFAULT

         The following are summaries of events of default under the Indenture
with respect to any series of our debt securities:

        o       default in the payment of any interest on any debt  security of
                that series when it becomes due and payable, and continuance of
                such default for a period of 30 days;

        o       default in the payment of the principal of (or premium, if any,
                on),  any debt  security of that series when it becomes due and
                payable;

        o       default in the performance,  or breach, of any of our covenants
                or   warranties  in  the  Indenture  in  respect  of  our  debt
                securities  of that series (other than a covenant or warranty a
                default in the  performance  of which or the breach of which is
                specifically  dealt  with  elsewhere  in  the  Indenture),  and
                continuance  of such  default or breach for a period of 60 days
                after receipt by us of written  notice to us,  specifying  such
                default or breach, by the Trustee or by the holders of at least
                25% in principal  amount of all outstanding  debt securities of
                any series affected thereby;

        o       if an  event  of  default  (as  defined  in  any  indenture  or
                instrument under which we or one of our Restricted Subsidiaries
                has at the  time of the  Indenture  or  shall  thereafter  have
                outstanding any  indebtedness  for borrowed money) shall happen
                and be  continuing,  or we or any Restricted  Subsidiary  shall
                have  failed to pay  principal  amounts  with  respect  to such
                indebtedness  at maturity  and such event of default or failure
                to pay shall result in such indebtedness being declared due and
                payable or otherwise being accelerated, in either event so that
                an amount in excess of  the greater of US$75,000,000  and 2% of
                our  Shareholders'  Equity  shall be or become due and  payable
                upon such  declaration  or otherwise  accelerated  prior to the
                date on which the same  would  otherwise  have  become  due and
                payable (the "accelerated indebtedness"), and such acceleration
                shall not be rescinded or annulled, or such event of default or
                failure to pay under such indenture or instrument  shall not be
                remedied or cured,  whether by payment or otherwise,  or waived
                by the holders of such  accelerated  indebtedness,  then (i) if
                the accelerated  indebtedness  shall be as a result of an event
                of default which is not related to the failure to pay principal
                or interest on the terms,  at the times,  and on the conditions
                set out in any such  indenture or  instrument,  it shall not be
                considered  an event of default for  purposes of the  Indenture
                until 30 days after such indebtedness has been accelerated,  or
                (ii) if the accelerated indebtedness shall occur as a result of
                such failure to pay  principal or interest or as a result of an
                event  of  default  which  is  related  to the  failure  to pay
                principal  or interest on the terms,  at the times,  and on the
                conditions set out in any such  indenture or  instrument,  then
                (A)  if  such  accelerated   indebtedness  is,  by  its  terms,
                Non-Recourse  Debt  to us or our  Restricted  Subsidiaries,  it
                shall not be considered an event of default for purposes of the
                Indenture; or (B) if such accelerated  indebtedness is recourse
                to  us or  our  Restricted  Subsidiaries,  any  requirement  in
                connection with such failure to pay or event of default for the
                giving of notice or the lapse of time or the  happening  of any
                further  condition,  event or act under such other indenture or
                instrument in connection  with such failure to pay principal or
                an  event  of  default  shall be  applicable  together  with an
                additional  seven  days  before  being  considered  an event of
                default for purposes of the Indenture;

        o       the entry of decree or order by a court having  jurisdiction in
                the premises adjudging us a bankrupt or insolvent, or approving
                as   properly   filed  a   petition   seeking   reorganization,
                arrangement,  adjustment or  composition of or in respect of us
                under  the  Bankruptcy   and   Insolvency  Act  (Canada),   the
                Companies'  Creditors  Arrangement  Act  (Canada)  or any other
                applicable   insolvency   law,   or   appointing   a  receiver,
                liquidator,   assignee,   trustee,   sequestrator  (or  similar
                official) of us or of any substantial part of our property,  or


                                      17


                ordering the winding up or liquidation of our the affairs,  and
                the  continuance  of any such decree or order  unstayed  and in
                effect for a period of 90 consecutive days;

        o       the  institution  by us of  proceedings  to  be  adjudicated  a
                bankrupt or insolvent,  or the consent by us to the institution
                of  bankruptcy  or  insolvency  proceedings  against us, or the
                filing  by  us of a  petition  or  answer  or  consent  seeking
                reorganization  or relief under the  Bankruptcy  and Insolvency
                Act (Canada), the Companies' Creditors Arrangement Act (Canada)
                or any other applicable insolvency law, or the consent by us to
                the  filing of any such  petition  or to the  appointment  of a
                receiver, liquidator, assignee, trustee, sequestrator (or other
                similar  official)  of us or of  any  substantial  part  of our
                property,  or the making by us of an assignment for the benefit
                of  creditors,  or  the  admission  by it  in  writing  of  our
                inability to pay our debts generally as they become due; or

        o       any other  events of  default  provided  with  respect  to debt
                securities of that series.

        If an event of default  under the  Indenture  occurs and is  continuing
with respect to any series of our debt securities,  then and in every such case
the Trustee or the holders of at least 25% in aggregate principal amount of the
outstanding  debt  securities  of such  affected  series  may,  subject  to any
subordination  provisions thereof,  declare the entire principal amount (or, if
the debt securities of that series are original issue discount debt securities,
such portion of the  principal  amount as may be specified in the terms of that
series)  of all debt  securities  of such  series  and all  accrued  and unpaid
interest thereon to be immediately due and payable.  However, at any time after
a declaration of acceleration with respect to any series of our debt securities
has been made, but before a judgment or decree for payment of the money due has
been obtained, the holders of a majority in principal amount of the outstanding
debt  securities of that series,  by written notice to us and the Trustee under
certain circumstances, may rescind and annul such acceleration.

        Reference  is  made  to  the   applicable   prospectus   supplement  or
supplements  relating to each series of our debt securities  which are original
issue  discount  debt  securities  for the  particular  provisions  relating to
acceleration  of the  maturity  of a portion  of the  principal  amount of such
original issue discount  securities upon the occurrence of any event of default
and the continuation thereof.

        Subject to certain limitations set forth in the Indenture,  the holders
of a majority in principal  amount of the  outstanding  debt  securities of all
series affected by an event of default shall have the right to direct the time,
method and place of conducting any  proceeding for any remedy  available to the
Trustee,  or  exercising  any trust or power  conferred  on the  Trustee,  with
respect to the debt securities of all series affected by such event of default.

        No  holder  of a debt  security  of any  series  will have any right to
institute any proceeding with respect to the Indenture,  or for the appointment
of a receiver or a Trustee, or for any other remedy thereunder, unless:

        o       such holder has previously  given to the Trustee written notice
                of a  continuing  event of  default  with  respect  to the debt
                securities of such series affected by such event of default;

        o       the holders of at least 25% in  aggregate  principal  amount of
                the  outstanding  debt securities of such series (voting as one
                class)  affected  by such  event of default  have made  written
                request,  and such holder or holders  have  offered  reasonable
                indemnity,  to the  Trustee to  institute  such  proceeding  as
                Trustee; and

        o       the Trustee has failed to institute  such  proceeding,  and has
                not  received  from the  holders  of a  majority  in  aggregate
                principal  amount of the  outstanding  debt  securities of such
                series   affected   by  such  event  of  default  a   direction
                inconsistent  with  such  request,  within 60 days  after  such
                notice, request and offer.

        However,  such  above-mentioned  limitations  do  not  apply  to a suit
instituted by the holder of a debt security for the  enforcement  of payment of
the  principal of or any premium or interest on such debt  security on or after
the applicable due date specified in such debt security.

        We will  annually  furnish to the Trustee a statement by certain of our
officers  as to  whether  or not we,  to the  best of their  knowledge,  are in
compliance  with all  conditions  and covenants of the  Indenture  and, if not,
specifying all such known defaults.


                                      18


DEFEASANCE AND COVENANT DEFEASANCE

        Unless otherwise specified in the applicable prospectus supplement, the
Indenture  provides that, at our option, we will be discharged from any and all
obligations in respect of the  outstanding  debt  securities of any series upon
irrevocable  deposit with the  Trustee,  in trust,  of money and/or  government
securities which will provide money in an amount sufficient in the opinion of a
nationally  recognized firm of independent  chartered accountants (as evidenced
by an officer's  certificate  delivered to the Trustee) to pay the principal of
(and  premium,  if any,  and each  installment  of  interest,  if any,  on) the
outstanding  debt  securities  of such  series  (hereinafter  referred  to as a
"defeasance") (except with respect to the authentication, transfer, exchange or
replacement of our debt securities or the maintenance of a place of payment and
certain other  obligations set forth in the Indenture).  Such trust may only be
established if among other things:

        o       we have  delivered  to the Trustee an opinion of counsel in the
                United States  stating that (i) we have received from, or there
                has been published by, the Internal  Revenue  Service a ruling,
                or (ii) since the date of execution of the Indenture, there has
                been a change in the applicable U.S. federal income tax law, in
                either case to the effect  that the holders of the  outstanding
                debt securities of such series will not recognize income,  gain
                or loss for U.S.  federal  income tax  purposes  as a result of
                such defeasance and will be subject to U.S.  federal income tax
                on the same  amounts,  in the same manner and at the same times
                as  would  have  been  the  case  if  such  defeasance  had not
                occurred;

        o       we have  delivered  to the  Trustee  an  opinion  of counsel in
                Canada or a ruling from the Canada Revenue Agency to the effect
                that the holders of the  outstanding  debt  securities  of such
                series will not  recognize  income,  gain or loss for  Canadian
                federal or provincial  income or other tax purposes as a result
                of such  Defeasance and will be subject to Canadian  federal or
                provincial  income  and other tax on the same  amounts,  in the
                same  manner  and at the same times as would have been the case
                had such  defeasance not occurred (and for the purposes of such
                opinion, such Canadian counsel shall assume that holders of the
                outstanding  debt securities of such series include holders who
                are not resident in Canada);

        o       no event of default or event that,  with the passing of time or
                the giving of notice,  or both,  shall  constitute  an event of
                default  shall have  occurred and be  continuing on the date of
                such deposit; and

        o       we are not an  "insolvent  person"  within  the  meaning of the
                Bankruptcy  and  Insolvency  Act  (Canada)  on the date of such
                deposit or at any time during the period ending on the 91st day
                following such deposit.

        We  may  exercise  our  defeasance  option  notwithstanding  our  prior
exercise of our Covenant Defeasance option described in the following paragraph
if we meet the  conditions  described in the preceding  sentence at the time we
exercise the defeasance option.

        The Indenture  provides  that, at our option,  unless and until we have
exercised our Defeasance  option described in the preceding  paragraph,  we may
omit to comply with the "Limitation on Liens" covenant,  certain aspects of the
"Consolidation,  Amalgamation,  Merger and Sale of Assets" covenant and certain
other covenants and such omission shall not be deemed to be an event of default
under the  Indenture  and our  outstanding  debt  securities  upon  irrevocable
deposit with the Trustee, in trust, of money and/or government securities which
will  provide  money in an amount  sufficient  in the  opinion of a  nationally
recognized  firm of  independent  chartered  accountants  (as  evidenced  by an
officer's  certificate  delivered to the Trustee) to pay the  principal of (and
premium, if any, and each installment of interest,  if any, on) the outstanding
debt  securities  (hereinafter  referred to as  "covenant  defeasance").  If we
exercise our covenant  defeasance  option,  the obligations under the Indenture
other than with respect to such  covenants and the events of default other than
with  respect to such  covenants  shall  remain in full force and effect.  Such
trust may only be established if, among other things:

        o       we have  delivered  to the Trustee an opinion of counsel in the
                United States to the effect that the holders of our outstanding
                debt  securities  will not recognize  income,  gain or loss for
                U.S.  federal  income tax purposes as a result of such covenant
                defeasance  and will be subject to U.S.  federal  income tax on
                the same  amounts,  in the same manner and at the same times as
                would have been the case if such  covenant  defeasance  had not
                occurred;


                                      19


        o       we have  delivered  to the  Trustee  an  opinion  of counsel in
                Canada or a ruling from the Canada Revenue Agency to the effect
                that the holders of our  outstanding  debt  securities will not
                recognize  income,   gain  or  loss  for  Canadian  federal  or
                provincial  income  or other tax  purposes  as a result of such
                covenant  defeasance and will be subject to Canadian federal or
                provincial  income  and other tax on the same  amounts,  in the
                same  manner  and at the same times as would have been the case
                had such covenant defeasance not occurred (and for the purposes
                of such  opinion,  such  Canadian  counsel  shall  assume  that
                holders of our outstanding debt securities  include holders who
                are not resident in Canada);

        o       no event of default or event that,  with the passing of time or
                the giving of notice,  or both,  shall  constitute  an event of
                default  shall have  occurred and be  continuing on the date of
                such deposit; and

        o       we are not an  "insolvent  person"  within  the  meaning of the
                Bankruptcy  and  Insolvency  Act  (Canada)  on the date of such
                deposit or at any time during the period ending on the 91st day
                following such deposit.

MODIFICATION AND WAIVER

         Modifications and amendments of the Indenture may be made by us and
the Trustee with the consent of the holders of a majority in principal amount
of the outstanding debt securities of each series issued under the Indenture
affected by such modification or amendment (voting as one class); PROVIDED,
HOWEVER, that no such modification or amendment may, without the consent of
the holder of each outstanding debt security of such affected series:

        o       change  the  stated  maturity  of  the  principal  of,  or  any
                installment of interest, if any, on any debt security;

        o       reduce  the  principal  amount  of  (or  premium,  if  any,  or
                interest, if any, on) any debt security;

        o       reduce the amount of principal of a debt security  payable upon
                acceleration of the maturity thereof;

        o       change the place of payment;

        o       change the currency of payment of principal of (or premium,  if
                any, or interest, if any, on) any debt security;

        o       impair the right to institute  suit for the  enforcement of any
                payment on or with respect to any debt security;

        o       reduce the percentage of principal  amount of outstanding  debt
                securities of such series,  the consent of the holders of which
                is required for  modification  or  amendment of the  applicable
                Indenture or for waiver of compliance  with certain  provisions
                of the Indenture or for waiver of certain defaults; or

        o       modify  any  provisions  of  the  Indenture   relating  to  the
                modification  and  amendment of the  Indenture or the waiver of
                past defaults or covenants except as otherwise specified in the
                Indenture.

        The holders of a majority in principal  amount of our outstanding  debt
securities of any series may on behalf of the holders of all debt securities of
that series waive,  insofar as that series is concerned,  compliance by us with
certain restrictive  provisions of the Indenture.  The holders of a majority in
principal  amount of  outstanding  debt  securities of any series may waive any
past default under the Indenture with respect to that series,  except a default
in the payment of the principal of (or premium,  if any) and interest,  if any,
on any debt  security of that  series or in respect of a provision  which under
the Indenture  cannot be modified or amended  without the consent of the holder
of each outstanding debt security of that series.

        The Indenture or the debt  securities  may be amended or  supplemented,
without the consent of any holder of such debt  securities,  in order to, among
other things, cure any ambiguity or inconsistency or to make any change, in any
case,  that does not have a  materially  adverse  effect  on the  rights of any
holder of such debt securities.


                                      20


CONSENT TO JURISDICTION AND SERVICE

        Under the  Indenture,  we irrevocably  appoint CT  Corporation  System,
111-8th  Avenue,  13th Floor,  New York, New York, as our authorized  agent for
service of process in any suit or proceeding  arising out of or relating to our
debt securities or the Indenture and for actions brought under federal or state
securities laws in any federal or state court located in New York, New York and
irrevocably submit to the non-exclusive jurisdiction of any such court.

GOVERNING LAW

        Our debt securities and the Indenture will be governed by and construed
in accordance with the laws of the State of New York.

ENFORCEABILITY OF JUDGMENTS

        Since  most of our  assets,  as well as the  assets  of a number of our
directors and officers, are outside the United States, any judgment obtained in
the United States against us or certain of our directors or officers, including
judgments with respect to the payment of principal on any debt securities,  may
not be collectible within the United States.

        We have been informed by Macleod Dixon LLP, our Canadian counsel,  that
there  is doubt  as to the  enforceability  in  Canada  by a court in  original
actions,  or in actions to enforce  judgments of United States courts, of civil
liabilities  predicated solely upon the United States federal  securities laws.
Therefore,  it may not be possible  to enforce  those  actions  against us, our
directors and officers or the experts named in this prospectus.

        Because  the  Trustee is located  in the United  States,  it may not be
possible for  purchasers  of our debt  securities  outside the United States to
effect  service of process  outside  the United  States upon the Trustee nor to
enforce against the Trustee,  outside the United States,  judgments obtained in
courts  outside  the  United  States.  Also it may not be  possible  to enforce
judgments of non-U.S. courts against the Trustee in the United States.

                                  RISK FACTORS

        IN  ADDITION  TO THE RISK  FACTORS  SET FORTH  BELOW,  ADDITIONAL  RISK
FACTORS  RELATING TO OUR BUSINESS ARE DISCUSSED IN OUR ANNUAL  INFORMATION FORM
AND  OUR  MANAGEMENT'S   DISCUSSION  AND  ANALYSIS,   WHICH  RISK  FACTORS  ARE
INCORPORATED HEREIN BY REFERENCE. Prospective purchasers of the debt securities
should consider carefully the risk factors set forth below as well as the other
information  contained in and  incorporated by reference in this prospectus and
in the applicable  prospectus  supplement before purchasing the debt securities
offered  hereby.  If any event arising from these risks  occurs,  our business,
prospects,  financial  condition,  results of operations or cash flows, or your
investment in the debt securities could be materially adversely affected.

THERE CAN BE NO  ASSURANCE AS TO THE  LIQUIDITY  OF THE TRADING  MARKET FOR THE
DEBT SECURITIES OR THAT A TRADING MARKET FOR THE DEBT SECURITIES WILL DEVELOP.

        There is no public market for the debt securities and, unless otherwise
specified in the applicable  prospectus  supplement,  we do not intend to apply
for listing of the debt  securities on any  securities  exchanges.  If the debt
securities are traded after their initial  issue,  they may trade at a discount
from their initial offering prices depending on prevailing  interest rates, the
market for similar  securities and other factors,  including  general  economic
conditions  and our  financial  condition.  There can be no assurance as to the
liquidity  of the  trading  market  for the debt  securities  or that a trading
market for the debt securities will develop.

CREDIT  RATINGS  MAY  NOT  REFLECT  ALL  RISKS  OF AN  INVESTMENT  IN THE  DEBT
SECURITIES AND MAY CHANGE.

        Credit ratings may not reflect all risks  associated with an investment
in the debt  securities.  Any credit ratings applied to the debt securities are
an  assessment  of our ability to pay our  obligations.  Consequently,  real or
anticipated  changes in the credit  ratings  will  generally  affect the market
value of the debt securities.  The credit ratings, however, may not reflect the
potential  impact  of risks  related  to  structure,  market  or other  factors
discussed  herein on the value of the debt  securities.  There is no  assurance


                                      21


that any credit rating  assigned to the debt  securities  will remain in effect
for any  given  period  of time or that  any  rating  will  not be  lowered  or
withdrawn entirely by the relevant rating agency.

CHANGES  IN  INTEREST  RATES  MAY CAUSE  THE  VALUE OF THE DEBT  SECURITIES  TO
DECLINE.

        Prevailing  interest rates will affect the market price or value of the
debt  securities.  The market price or value of the debt securities may decline
as prevailing interest rates for comparable debt instruments rise, and increase
as prevailing interest rates for comparable debt instruments decline.

THE DEBT SECURITIES WILL BE EFFECTIVELY SUBORDINATED TO CERTAIN INDEBTEDNESS OF
OUR CORPORATE AND PARTNERSHIP SUBSIDIARIES.

        The debt securities will be our unsubordinated and unsecured obligation
and,  unless  otherwise  provided with respect to a series of debt  securities,
will rank equally with all of our other unsecured,  unsubordinated obligations.
We  conduct  a  substantial  portion  of our  business  through  corporate  and
partnership  subsidiaries.  Our  obligations  under the debt securities will be
structurally   subordinate  to  all  existing  and  future   indebtedness   and
liabilities,  including trade payables, of any of our corporate and partnership
subsidiaries.

                       CERTAIN INCOME TAX CONSIDERATIONS

        The applicable  prospectus  supplement will describe  certain  Canadian
federal income tax consequences to an investor of acquiring any debt securities
offered thereunder,  including,  for investors who are non-residents of Canada,
whether the  payments of principal  and  interest,  if any,  will be subject to
Canadian non-resident withholding tax.

        The applicable  prospectus  supplement will also describe  certain U.S.
federal income tax consequences of the  acquisition,  ownership and disposition
of any debt securities  offered thereunder by an initial investor who is a U.S.
person (within the meaning of the U.S.  Internal Revenue Code),  including,  to
the  extent  applicable,  any such  consequences  relating  to debt  securities
payable in a currency other than the U.S.  dollar,  issued at an original issue
discount for U.S.  federal income tax purposes or containing  early  redemption
provisions or other special items.

                              PLAN OF DISTRIBUTION

        We may offer and sell debt  securities  to or through  underwriters  or
dealers and also may sell debt  securities  directly to  purchasers  or through
agents.  These debt  securities  may be offered and sold in Canada,  the United
States and elsewhere where permitted by law.

        The  distribution of debt securities of any series may be effected from
time to time in one or more transactions:

        o       at a fixed price or prices, which may be changed;

        o       at market prices prevailing at the time of sale; or

        o       at  prices  related  to such  prevailing  market  prices  to be
                negotiated with purchasers.

        In  connection  with  the  sale of debt  securities,  underwriters  may
receive  compensation  from us or from  purchasers of debt  securities for whom
they may act as agents in the form of concessions or commissions. Underwriters,
dealers and agents that  participate in the distribution of debt securities may
be deemed to be underwriters  and any commissions  received by them from us and
any  profit  on the  resale  of debt  securities  by them may be  deemed  to be
underwriting  commissions  under the United States  Securities  Act of 1933, as
amended (the "Securities Act").

        The prospectus  supplement  relating to each series of debt  securities
will also set forth the terms of the offering of the debt securities, including
to the extent  applicable,  the initial  offering price,  our proceeds from the
offering, the underwriting concessions or commissions,  and any other discounts
or concessions to be allowed or reallowed to dealers. Underwriters with respect
to each series sold to or through  underwriters will be named in the prospectus
supplement relating to such series.


                                      22


        Under agreements which may be entered into by us, underwriters, dealers
and  agents who  participate  in the  distribution  of debt  securities  may be
entitled  to  indemnification  by us  against  certain  liabilities,  including
liabilities under the Securities Act. The underwriters, dealers and agents with
whom we enter into agreements may be customers of, engage in transactions  with
or perform services for us in the ordinary course of business.

        Each series of debt  securities  will be a new issue of securities with
no  established  trading  market.  Unless  otherwise  specified in a prospectus
supplement  relating to a series of debt  securities,  the debt securities will
not be listed on any securities  exchange or on any automated  dealer quotation
system.  Certain  broker-dealers may make a market in the debt securities,  but
will not be obligated  to do so and may  discontinue  any market  making at any
time without notice.  We cannot assure you that any  broker-dealer  will make a
market  in the debt  securities  of any  series or as to the  liquidity  of the
trading market, if any, for the debt securities of any series.

                               INTEREST COVERAGE

        The following sets forth our interest  coverage  ratios  calculated for
the twelve  month period  ended  December  31, 2005 based on audited  financial
information  and June 30, 2006 based on unaudited  financial  information.  The
interest  coverage ratios set out below have been prepared and included in this
prospectus in accordance with Canadian  disclosure  requirements  and have been
calculated based on information  prepared in accordance with Canadian GAAP. The
interest  coverage  ratios  set out below do not  purport to be  indicative  of
interest  coverage ratios for any future periods.  The interest coverage ratios
do not give effect to the debt securities  offered by this prospectus since the
aggregate principal amount of debt securities that will be issued hereunder and
the terms of issue are not presently known.

                                           DECEMBER 31, 2005    JUNE 30, 2006
                                           -----------------    -------------

Interest coverage on long-term debt:
   Net earnings..........................      13.0 times         22.5 times
   Cash flow.............................      20.9 times         24.3 times


        Interest coverage on long-term debt on a net earnings basis is equal to
net  earnings  before  interest on long-term  debt and income taxes  divided by
interest  expense on long-term debt.  Interest  coverage on long-term debt on a
cash flow basis is equal to cash flow before interest expense on long-term debt
and cash  income  taxes  divided by interest  expense on  long-term  debt.  For
purposes  of  calculating  the  interest  coverage  ratios  set  forth  herein,
long-term debt includes the current portion of long-term debt.

                                 LEGAL MATTERS

        Unless otherwise  specified in the prospectus  supplement relating to a
series of debt securities,  certain legal matters relating to Canadian law will
be passed upon for us by Macleod Dixon LLP, Calgary,  Alberta,  Canada. Certain
legal  matters in  connection  with the offering  relating to United States law
will be passed upon for us by Paul, Weiss, Rifkind, Wharton & Garrison LLP, New
York,  New York. In addition,  certain legal matters  relating to United States
law will be passed upon for any  underwriters,  dealers or agents by Shearman &

Rifkind,  Wharton &  Garrison  LLP as a group  beneficially  own,  directly  or
indirectly, less than 1% of any class of our securities.

INDEMNIFICATION

ENCANA CORPORATION

         Under the CANADA BUSINESS CORPORATIONS ACT (the "CBCA"), EnCana
Corporation ("EnCana") may indemnify a present or former director or officer
of EnCana or another individual who acts or acted at EnCana's request as a
director or officer, or an individual acting in a similar capacity, of another
entity, against all costs, charges and expenses, including an amount paid to
settle an action or satisfy a judgment, reasonably incurred by the individual
in respect of any civil, criminal, administrative, investigative or other
proceeding in which the individual is involved because of that association
with EnCana or other entity. EnCana may not indemnify an individual unless the
individual acted honestly and in good faith with a view to the best interests
of EnCana, or, as the case may be, to the best interests of the other entity
for which the individual acted as a director or officer or in a similar
capacity at EnCana's request and in the case of a criminal or administrative
action or proceeding that is enforced by a monetary penalty, the individual
had reasonable grounds for believing that the conduct was lawful. The
indemnification may be made in connection with a derivative action only with
court approval. The aforementioned individuals are entitled to indemnification
from EnCana as a matter of right if they were not judged by the court or other
competent authority to have committed any fault or omitted to do anything that
the individual ought to have done. EnCana may advance moneys to the individual
for the costs, charges and expenses of a proceeding; however, the individual
shall repay the moneys if the individual does not fulfill the conditions set
out above.

         The by-laws of EnCana provide that, subject to the limitations
contained in the CBCA, EnCana shall indemnify a director or officer, a former
director or officer, or a person who acts or acted at EnCana's request as a
director or officer of a body corporate of which EnCana is or was a
shareholder or creditor, and his heirs and legal representatives against all
costs, charges and expenses, including an amount paid to settle an action or
satisfy a judgment, reasonably incurred by him in respect of any civil,
criminal or administrative action or proceeding to which he was made a party
by reason of being or having been a director or officer of the corporation or
such body corporate, if he acted honestly and in good faith with a view to the
best interests of the corporation, and in the case of a criminal or
administrative action or proceeding that is enforced by a monetary penalty, he
had reasonable grounds for believing that his conduct was lawful.

         The by-laws of EnCana provide that EnCana may, subject to the
limitations contained in the CBCA, purchase, maintain, or participate in
insurance for the benefit of any director, officer, or certain other persons,
as such against any liability incurred by him in his capacity as a director or
officer of EnCana or as a director or officer of any body corporate where he
acts or acted in that capacity at EnCana's request. EnCana has purchased third
party director and officer liability insurance.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers or persons
controlling EnCana pursuant to the foregoing provisions, EnCana has been
informed that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is therefore unenforceable.
