The Registrant may indemnify a director or officer of the Registrant, a former director or officer of the Registrant or another individual who acts or acted at the Registrant'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 judgement, 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 the Registrant or other entity. However, the Registrant may advance moneys to a director, officer or other individual for the costs, charges and expenses of a proceeding referred to above. The individual shall repay the moneys if the individual does not fulfil the conditions in (a) and (b) below. The Registrant may not indemnify an individual unless the individual (a) acted honestly and in good faith with a view to the best interests of the Registrant, or, as the case may be, to the best interests of the other entity for which the individual acted as director or officer or in a similar capacity at the Registrant's request; and (b) 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 individual's conduct was lawful. The Registrant may with the approval of a court, indemnify an individual referred to above, or advance moneys for the costs, charges and expenses of a proceeding, in respect of an action by or on behalf of the Registrant or other entity to procure a judgement in its favor, to which the individual is made a party because of the individual's association with the Registrant or other entity as described above against all costs, charges and expenses reasonably incurred by the individual in connection with such action, if the individual fulfils the conditions set out in (a) and (b) above. Notwithstanding the foregoing, an individual is entitled to indemnity from the Registrant in respect of all costs, charges and expenses, reasonably incurred by the individual in the defense of any civil, criminal, administrative or other proceeding to which the individual is subject because of the individuals association with the Registrant or other entity referred to above, if the individual seeking indemnity was not judged by a court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done, and if the individual fulfils the conditions set out in (a) and (b) above.

A by-law of the Registrant provides that the Registrant shall indemnify a director or officer of the Registrant, a former director or officer of the Registrant or a person who acts or acted at the Registrant's request as a director or officer of a corporate body of which the Registrant is or was a shareholder or creditor, and the heirs and legal representatives thereof, to the extent permitted by the Canada Business Corporations Act ("CBCA") or otherwise by law.

The Registrant maintains a directors' and officers' liability policy which provides coverage to the Registrant for all directors' and officers' related claims, losses and cost in any year, subject to policy limits and deductibles.

5

The Registrant has entered into indemnification agreements with each of its officers and directors pursuant to which they are indemnified to the fullest extent permitted by the CBCA. Pursuant to the terms of these agreements the Registrant maintains errors and omissions insurance for its officers and directors while they remain an officer or director and for a period of 10 years thereafter.

                              pages to the Registration Statement)

Item 9.   UNDERTAKINGS.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) shall not apply to information contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's Annual Report pursuant to section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

7

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Dear Gentlemen:

RE: TRANSALTA CORPORATION
REGISTRATION STATEMENT ON FORM S-8

We are counsel to TransAlta Corporation (the "Corporation"), a corporation incorporated under the Canada Business Corporations Act.

We refer to the filing by the Corporation of the above-captioned Registration Statement on Form S-8 (the "Registration Statement") under the Securities Act of 1933, as amended, covering the registration of an aggregate of 1,500,000 common shares without par value of the Corporation (the "Shares"), together with attached common share purchase rights (the "Rights"), issuable by the Corporation as described in the Registration Statement. The terms of the Rights are set forth in the Shareholder Rights Plan Agreement dated as of October 13, 1992, as amended and restated as of November 26, 1992, May 14, 1998 and May 3, 2001 (the "Rights Agreement") between the Corporation and CIBC Mellon Trust Company, as Rights Agent.

We have examined the Articles of the Corporation, resolutions of the Board of Directors of the Corporation in respect of the issuance of the Shares and original, reproduced or certified copies of such records of the Corporation and such agreements, certificates of public officials, certificates of officers and representatives of the Corporation and others, and such other documents, papers, statutes and authorities as we deem necessary to form the basis of the opinions hereinafter expressed. In such examination, we have assumed the genuineness of all signatures and the conformity to original documents of all documents supplied to us as copies. As to various questions of fact material to such opinions, we have relied upon the records of the Corporation and upon statements and certificates of officers and representatives of the Corporation and others.

Based on and subject to the foregoing, we are of the opinion that:

1. The Shares have been duly authorized, and, when issued in accordance with the TransAlta Corporation Stock Option Plan, as amended, referred to in the Registration Statement, will be legally issued by the Corporation as fully paid and non-assessable shares in the capital of the Corporation.

2. The Rights associated with the Shares referred to in paragraph 1 will be legally issued when (i) such Rights have been duly issued in accordance with the terms of the Rights Agreement and (ii) the associated Shares have been duly issued as set forth in paragraph 1.

We hereby consent to your filing a copy of this Opinion as an exhibit to said Registration Statement and to all references to our firm included in or made part of the Registration Statement.

Yours very truly,

MCCARTHY TETRAULT LLP
