Item 1.     Security and Issuer.

            This Amendment No. 1 to Schedule 13D amends (i) the Statement on
Schedule 13D relating to the Class A Subordinate Voting Shares (the "Class A
Shares") of Tesma International Inc. (the "Issuer") originally filed on
February 14, 2002, by the Stronach Trust ("Stronach Trust"), a trust formed
under the laws of Ontario, Canada, 445327 Ontario Limited ("445327"), an
Ontario, Canada corporation, Magna International Inc. ("Magna"), an Ontario,
Canada corporation, and 1265058 Ontario Inc. ("1265058"), an Ontario, Canada
corporation, and (ii) the Statement on Schedule 13D relating to the Class A
Shares originally filed on September 9, 2003 by Frank Stronach. This Amendment
No. 1 is filed by Stronach Trust, 445327, Magna, 1265058 and Frank Stronach.

Item 2.     Identity and Background

            Mr. Stronach's principal business address is Badener Strasse 12,
Oberwaltersdorf, Austria 2522. Mr. Stronach is a partner of Stronach & Co
("S&Co"), an entity that provides consulting services to certain subsidiaries
of Magna. In addition, Mr. Stronach is the Chairman of the Board of Magna, the
Chairman of the Board of MI Developments Inc. ("MID") and the Chairman of the
Board of Magna Entertainment Corp. ("MEC").

            During the last five years, Mr. Stronach has not been: (i)
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors); or (ii) a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction as a result of which he was or

Stronach is a citizen of Austria.

Item 3.     Source and Amount of Funds or Other Consideration.

            Item 3 of the Original 13D is amended to disclose that the Class A
Subordinate Voting Shares of Magna ("Magna Class A Shares") and cash to be
paid as purchase consideration for the Class A Shares acquired by Magna in the
proposed transaction will be provided by Magna (with respect to such cash,
from internal funds).

Item 4.     Purpose of Transaction.

            On October 25, 2004, Magna issued a press release (the "Press
Release") disclosing that it intends to acquire all the outstanding Class A

CUSIP No. 881908107              SCHEDULE 13D               Page 8 of 9 Pages
------------------------------------------------------------------------------

                  Mr. Stronach is a principal in Stronach & Co. ("S&Co."), a
                  consulting firm providing services to certain subsidiaries
                  of Magna, and may be deemed to be the beneficial owner of
                  250,000 Class A Shares issuable upon exercise of a currently
                  outstanding option (the "S&Co Option") held by S&Co. that
                  was issued to S&Co. on October 25, 1999 in consideration for
                  consulting services to be rendered to the Issuer pursuant to
                  a consulting agreement with S&Co. The S&Co Option will vest
                  and become exercisable with respect to an additional 50,000
                  Class A Shares on October 25, 2005 provided that the
                  consulting agreement currently in effect between S&Co. and
                  the Issuer is not terminated prior to such date. If the
                  proposed acquisition by Magna is consummated as planned, the
                  S & Co Option will cease to be exercisable for Class A
                  Shares. The filing of this statement shall not be construed
                  as an admission that Mr. Stronach beneficially owns any
                  Class A Shares that are or may be deemed to be beneficially
                  owned by S&Co. Without limitation of the foregoing, Mr.
                  Stronach disclaims beneficial ownership of such Class A
                  Shares for purposes other than U.S. securities law purposes.

                  Mr. Stronach acts as one of four trustees of the Stronach
                  Trust. The remaining trustees of the Stronach Trust are
                  members of the reporting person's family. Mr. Stronach is
                  entitled to appoint additional trustees and to remove
                  trustees. Determinations by the Stronach Trust are made by a
                  majority of the trustees, which majority must include the
                  reporting person.

                  The Stronach Trust owns all the outstanding shares of 445327
                  Ontario Limited ("445327"), of which the reporting person is
                  the sole director. 445327 holds 726,829 Class B Shares of
                  Magna, such shares representing approximately 56.4% of the
                  total votes carried by the outstanding voting stock of
                  Magna. The reporting person may be deemed to be the
                  beneficial owner of 14,253,448 Class A Shares beneficially
                  owned by Magna, 1128969 and 1620364 Ontario Inc., a wholly
                  owned subsidiary of Magna ("1620364") (including 14,233,900
                  Class A Shares issuable upon conversion of an equivalent
                  number of Class B Shares held in the aggregate by Magna and
                  1128969). The filing of this statement shall not be
                  construed as an admission that Mr. Stronach beneficially
                  owns any Class A Shares that are or may be deemed to be
                  beneficially owned by the Stronach Trust, 445327, Magna,
                  1128969 or 1620364. Without limitation of the foregoing, Mr.
