                               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  the  material  terms  and  provisions  of the debt
securities.  However, 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
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


                                       6


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;

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


                                       7


        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
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,


                                       8


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.

        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


                                       9


               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.

               was secured by the prior Lien plus improvements on such property

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


                                      13


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.

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


                                      14


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
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:


                                      15


        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
               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:


                                      16


        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 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


                                      17


        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.

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:


                                      18


        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;

        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


                                      19


        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.

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.


                                      20


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
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.


                                      21


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.

        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


                                      22


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.

        Further  information with respect to our net earnings and cash flow may
be  found in our  consolidated  statements  of  earnings  and our  consolidated
statements of cash flows incorporated by reference herein.

        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.
