Thomson Increases Quarterly Dividend

(All amounts are in U.S. dollars)

STAMFORD, Conn., April 27, 2004 — The Board of Directors of The Thomson Corporation (NYSE: TOC; TSX: TOC) today declared an increase in the quarterly dividend on the company's common stock of one-half cent per share, or $0.02 on an annualized basis. The new quarterly dividend of $0.19 per share is payable on June 15, 2004 to common shareholders of record as of May 20, 2004. On an annualized basis, the new dividend rate is $0.76 per share.

        On October 30, 2003, the Thomson Board also increased the quarterly dividend one-half cent per share. At that time, the Board announced its intention to move its annual review of the company's dividend policy to the second quarter, rather than the fourth quarter, to more closely align the dividend review with the company's overall business planning calendar. The Board is scheduled to review the dividend again in the second quarter of 2005.
