                       ATI receives OSC Notice of Hearing

MARKHAM, Ontario - January 16, 2003 - ATI Technologies Inc. (TSX: ATY, NASDAQ:
ATYT) today announced that Staff of the Ontario Securities Commission has filed
a Notice of Hearing and Statement of Allegations in relation to ATI and others.
The Notice, a copy of which is attached, alleges that ATI failed to disclose
information concerning the shortfall in revenues and earnings that occurred in
the third quarter of fiscal 2000, as required by the listing rules of the
Toronto Stock Exchange. The Notice also alleges that ATI made a misleading
statement to Staff of the Commission in August 2000 regarding the events leading
up to the disclosure on May 24, 2000 of the shortfall.

Seven individuals are also named in the Notice. The Notice alleges that six of
these individuals, including K.Y. Ho, the Chief Executive Officer of ATI,
engaged in insider trading contrary to the Securities Act.

The Company takes these allegations seriously. As previously announced, a
Special Committee consisting of Paul Russo, who joined the board in January
2002, is conducting an independent review of the matters contained in Staff's
allegations. Mr. Peter Dey of Osler, Hoskin & Harcourt LLP is acting as a
special advisor to the Committee.
