FOR IMMEDIATE RELEASE

Thomson Announces Resumption of

Share Repurchase Program

STAMFORD, Conn., November 23, 2007 – The Thomson Corporation (NYSE: TOC; TSX: TOC), a leading provider of information solutions to business and professional customers worldwide, today announced it has resumed its share repurchase program (normal course issuer bid). Under the current program, the company may repurchase up to 15 million of its common shares. Thomson temporarily suspended repurchases prior to the company’s announcement of its proposed acquisition of Reuters Group PLC in May 2007.

Thomson continues to expect to receive regulatory clearance for the Reuters transaction in the first quarter of 2008. While the regulatory review process continues, integration planning efforts associated with the acquisition are proceeding on course.

Thomson has entered into a pre-defined plan with its broker to allow for the repurchase of common shares at times when Thomson ordinarily would not be active in the market due to its own internal trading blackout periods, insider trading rules or otherwise. This plan was adopted in accordance with the requirements of applicable Canadian securities laws and Rule 10b5-1 under the U.S. Securities Exchange Act of 1934.

The Thomson Corporation (www.thomson.com) is a global leader in providing essential electronic workflow solutions to business and professional customers.
