                                -----------------

              The headings and numbered responses set out below correspond to
the headings and numbered comments in the Comment Letter. The Company's
responses to the Staff's comments are as follows:

GENERAL

Form 40-F for the Fiscal Year Ended December 31, 2004
-----------------------------------------------------

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
---------------------------------------------------------------------------
Oil and Gas Reserves, Page 24
-----------------------------

        1.   We have reviewed your response to prior comment number one and are
             unable to agree with your conclusion. As previously noted, the
             subtotal Undiscounted pre-tax cash flows is not contemplated by
             SFAS 69, as noted in Illustration 5 of the statement. Accordingly,
             we reissue our prior comment in its entirety.

Response to Comment 1
---------------------

             EnCana believes that SFAS 69 does not preclude the subtotal
             "Undiscounted pre-tax cash flows" and the disclosure of such a
             subtotal is beneficial to investors. However, to be responsive to
             staff's comment, EnCana proposes to remove such subtotal from all
             applicable future filings.

A) Principles of Consolidation, page 6
--------------------------------------

        2.   We have reviewed your response to prior comment number three. We
             note your interpretation that Canadian GAAP, unlike EITF 00-01 for
             US GAAP, has a broad definition of joint venture activity and as a
             result there are certain types of entities and arrangements that
             are permitted to be proportionately consolidated under Canadian
             GAAP that would not be under US GAAP. We also note your conclusion
             that Item 17(c)(2)(vii) is not applicable to you, based on your
             determination that there is no US GAAP reconciling item. Please
             clarify, if true, that the entities that you proportionately
             consolidate under Canadian GAAP have the characteristics both in
             terms of the industry and scope of operations and the legal form
             and elements of shared control contemplated by EITF 00-1.
             Additionally, as previously requested, please expand your
             accounting policy to identify the legal form of each entity and the
             nature of the activities in which the entity being proportionately
             consolidated is engaged. To the extent that differences exist
             between Canadian and US GAAP in your use of proportionate

<PAGE>

             consolidation, please expand your reconciliation to US GAAP
             disclosure to identify this as a reconciling item or explain that
             you have relied on an accommodation in Form 20-F and identify the
             factors that you satisfied to avail yourself of this accommodation.

Response to Comment 2
---------------------

             PLEASE CLARIFY, IF TRUE, THAT THE ENTITIES THAT YOU PROPORTIONATELY
             CONSOLIDATE UNDER CANADIAN GAAP HAVE THE CHARACTERISTICS BOTH IN
             TERMS OF INDUSTRY AND SCOPE OF OPERATIONS AND THE LEGAL FORM AND
             ELEMENTS OF SHARED CONTROL CONTEMPLATED BY EITF-00-01.

             The following is information on the scope of operations and legal
             form of EnCana's entities that are proportionately consolidated
             under Canadian GAAP. Substantially all items that are
             proportionately consolidated in EnCana's consolidated financial
             statements are undivided interests in jointly controlled assets,
             all related to the production of crude oil and natural gas, held by
             various wholly owned subsidiaries.

             Additionally, in its consolidated financial statements for the
             fiscal year ended December 31, 2004, EnCana proportionately
             consolidated two entities, both of which are unincorporated
             partnerships that carry on an active business of marketing natural
             gas liquids. These two partnerships are not material in relation to
             the EnCana consolidated financial statements. Collectively, they
             contain less than 0.3% of EnCana's total assets and less than 0.5%
             of EnCana's net earnings.

             The operating, investing and financing activities of these entities
             were determined in accordance with the partnership agreements. The
             significant financial policies of these entities were determined in
             conjunction with the other equity owner. As a partner in these
             unincorporated partnerships, EnCana holds an undivided interest in
             the assets, is proportionately liable for liabilities and no other
             separate legal entity exists. Accordingly, these two entities that
             EnCana proportionately consolidated in its consolidated financial
             statements for the fiscal year ended December 31, 2004 have the
             characteristics contemplated by EITF 00-01, as previously
             described.

             ADDITIONALLY, AS PREVIOUSLY REQUESTED, PLEASE EXPAND YOUR
             ACCOUNTING POLICY TO IDENTIFY THE LEGAL FORM OF EACH ENTITY AND
             NATURE OF THE ACTIVITIES IN WHICH THE ENTITY BEING PROPORTIONATELY
             CONSOLIDATED IS ENGAGED.

             In order to be responsive to the staff's comment, EnCana proposes
             to expand the note on "Principles of Consolidation" under EnCana's
             "Summary of Significant Accounting Policies" in the December 31,
             2005 consolidated financial statements and all future filings as
             applicable, with wording substantially similar to the following
             (the text below has been marked to show changes from the note
             disclosure relating to "Principles of Consolidation" in the Form
             40-F for EnCana's 2004 fiscal year):

             Principles of Consolidation

             The Consolidated Financial Statements include the accounts of
             EnCana Corporation and its subsidiaries ("EnCana" or the "Company")
             and are presented in accordance with Canadian generally accepted
             accounting principles. Information prepared in accordance with
             generally accepted accounting principles in the United States is
             included in Note 20.

             Investments in jointly controlled partnerships and unincorporated
             joint ventures carry on encana's exploration and production
             activity and are accounted for using the proportionate
             consolidation method, whereby encana's proportionate share of
             revenues, expenses, assets and liabilities are included in the
             accounts.

             Investments in companies and partnerships in which EnCana does not
             have a direct or joint control over the strategic operating,
             investing and financing decisions, but does have significant
             influence on them, are accounted for using the equity method.

             TO THE EXTENT THAT DIFFERENCES EXIST BETWEEN CANADIAN AND US GAAP
             IN YOUR USE OF PROPORTIONATE CONSOLIDATION, PLEASE EXPAND YOUR
             RECONCILIATION TO US GAAP DISCLOSURE TO IDENTIFY THIS AS A
             RECONCILING ITEM OR EXPLAIN THAT YOU HAVE RELIED ON AN
             ACCOMMODATION IN FORM 20-F AND IDENTIFY THE FACTORS THAT YOU
             SATISFIED TO AVAIL YOURSELF OF THIS ACCOMMODATION.

             EnCana acknowledges that differences exist between Canadian and
             U.S. GAAP with respect to proportionate consolidation. However,
             EnCana did not, in its consolidated financial statements for the
             fiscal year ended December 31, 2004, proportionately consolidate
             any entity that created differences between Canadian and U.S. GAAP
             in the use of proportionate consolidation. If, in the future,
             EnCana has an entity that creates this difference in its
             consolidation, EnCana's U.S. GAAP reconciliation note will be
             expanded as requested.
