The Thomson Corporation (NYSE: TOC; TSX: TOC), a leading provider of information solutions to business and professional customers worldwide, today announced that its controlling shareholder, The Woodbridge Company Limited, has indicated that it will reinvest 50% of its quarterly dividends in Thomson common shares during the first three quarters of 2008 in accordance with the terms of Thomson's dividend reinvestment plan (DRIP).

Reuters announced yesterday its intent to buy back up to 50 million of its ordinary shares prior to being acquired by Thomson. Thomson resumed its own buyback program on November 23 and remains committed to maintaining a strong capital structure and balance sheet. Woodbridge's reinvestment decision furthers this commitment and supports Thomson's and Reuters' independent share buyback programs.

All eligible Thomson shareholders may elect to reinvest their dividends in Thomson common shares at the prevailing market price under Thomson's DRIP.
