Magna International Inc.
337 Magna Drive, Aurora
Ontario, Canada L4G 7K1

Ladies and Gentlemen:

          We have acted as counsel for Magna International Inc., a corporation
organized under the laws of the Province of Ontario, Canada (the "Company"),
in connection with the proposed filing with the Securities and Exchange
Commission expected to be made on or about September 9, 2005 under the
Securities Act of 1933, as amended, of a Registration Statement on Form S-8
(the "Registration Statement") for the purpose of registering 400,000 Class A
Subordinate Voting Shares, without par value (the "Class A Shares"), of Magna
International Inc., together with such indeterminable amount of interests (the
"Interests") in The Magna Group of Companies Retirement Savings Plan (the
"Plan"), as may be purchased with contributions under the Plan. In such
capacity, we have examined the Articles of Arrangement and general By-Law of
the Company, the Plan, and such other documents of the Company as we have
deemed necessary or appropriate for the purposes of the opinion expressed
herein.

          Based upon the foregoing, we advise you that, in our opinion, (i)
the Class A Shares purchased with contributions under the Plan will be legally
issued, fully paid and nonassessable and (ii) the Interests, to the extent
such Interests vest to the benefit of the participants in the Plan, will have
been duly and validly authorized and will be valid Interests.

          We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name wherever appearing in the
Registration Statement.

                                           Very truly yours,


                                           /s/ Sidley Austin Brown & Wood LLP
