                      ATI President Announces Trading Plan

MARKHAM, ON - November 5, 2003 - ATI Technologies Inc. (TSX:ATY, NASDAQ:ATYT)
announced today that David Orton, President and COO of ATI, has advised the
company that he intends to enter into a trading plan to sell a portion of his
holdings of shares of the company. Under the terms of the trading plan, which
will comply with the requirements of the U.S. Securities and Exchange
Commission's Rule 10b5-1, Mr. Orton anticipates selling up to one million ATI
common shares, subject to market conditions. Assuming the planned sales are
completed, Mr. Orton will still hold over one million ATI shares including
common shares and vested options.

The SEC's Rule 10b5-1 permits senior  executives to adopt written  trading plans
at a time when they are not in possession of material non-public information and
to sell  shares  according  to that plan with  pre-determined  volume  and price
parameters. Sales under the plan will occur in a systematic manner with the goal
of minimal market impact by spreading such sales over a more extended  period of
time than would be available using traditional trading window periods.

Mr. Orton has advised that he intends to implement the trading plan in order to
achieve personal objectives for estate planning and investment diversification.
ATI shares will continue to be his most significant personal investment.
