also continue to make progress related to our proposed acquisition of Reuters and believe it will enable Thomson to best capitalize on long-term trends in the
marketplace," said Mr.&nbsp;Harrington. "Combined, Thomson-Reuters will be able to effectively address business and financial customers' growing demand for broader, faster and more integrated
information and solutions. Our respective businesses are extremely complementary, with little overlap in either geographic presence or product offering. Together, we will have a global footprint with
strong brands in North America, Europe and Asia. We believe the transaction will enhance competition and our customers continue to provide us with positive feedback on the benefits and value of
bringing Thomson and Reuters together."........ </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Thomson's proposed acquisition of Reuters Group&nbsp;PLC is progressing. The combined business, to be named Thomson-Reuters, will create a global leader in
electronic information services, trading systems and news. The transaction is currently being reviewed by the European Commission, the U.S.&nbsp;Department of Justice, the Canadian Competition
Bureau and other regulatory authorities. Thomson and Reuters recently provided a regulatory update on October&nbsp;8,&nbsp;2007. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"We
continue to hold productive discussions with regulators, and we remain hopeful that we can work with them to expedite the process and complete the transaction in or around the first
quarter of 2008," said Mr.&nbsp;Harrington......... </FONT></P>

<P><FONT SIZE=2><B>Business Outlook  </B></FONT></P>

<P><FONT SIZE=2>.......The
company's proposed acquisition of Reuters was announced in May&nbsp;2007..... </FONT></P>


<P><FONT SIZE=2><B>CAUTIONARY NOTE CONCERNING FACTORS THAT MAY AFFECT FUTURE RESULTS  </B></FONT></P>

<P><FONT SIZE=2>This
news release, in particular the discussion of the proposed acquisition of Reuters....includes forward-looking statements, such as the Corporation's beliefs and expectations regarding its
financial performance in 2007. These statements are based on certain assumptions and reflect the Corporation's current expectations. Forward-looking statements also include statements about the
Corporation's beliefs and expectations related to.....its beliefs that the proposed acquisition of Reuters will position Thomson to best capitalize on long-term trends in the marketplace
and that the combined business will be able to effectively address customers' growing demands for integrated information and solutions..... While Thomson believes that the proposed transaction with
Reuters will be approved by antitrust/competition authorities, there can be no assurance that required approvals will be obtained, how long it will take to obtain such approvals or what conditions, if
any, such authorities may impose. All forward-looking statements in this news release are subject to a number of risks and uncertainties that could cause actual results or events to differ materially
from current expectations. These risks and uncertainties include the failure of Reuters shareholders to approve the proposed transaction; the effect of regulatory conditions, if any, imposed by
regulatory authorities; the reaction of Thomson's and Reuters' customers, employees and suppliers to the proposed transaction; the ability to promptly and effectively integrate the businesses of
Thomson and Reuters after the transaction closes; and the diversion of management time on transaction-related issues. Some of the other factors that could cause actual results or events to differ
materially from current expectations are actions of competitors; failure to fully derive anticipated benefits from acquisitions and divestitures; failure to develop additional products and services to
meet customers' needs, attract new customers or expand into new geographic markets; and changes in the general economy. Additional factors are discussed in the Corporation's materials filed with the
securities regulatory authorities in Canada and the United&nbsp;States from time to time, including the Corporation's latest annual information form, which is also contained in its most recently
filed annual report on Form&nbsp;40-F......The Corporation disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new
information, future events or otherwise, other than as required by&nbsp;law. </FONT></P>

<P><FONT SIZE=2><B>ADDITIONAL INFORMATION  </B></FONT></P>

<P><FONT SIZE=2>.....This
document does not constitute an offer for sale of any securities or an offer or an invitation to purchase any such securities. Following satisfaction or waiver of the
pre-conditions to the proposed Reuters transaction, documents relating to the proposed transaction will be furnished to or filed with the SEC. Shareholders are urged to read such documents
regarding the proposed transaction if and when they become available, because they will contain important information. Shareholders will be able to obtain free copies of these documents, as well as
other filings containing information about the companies, without charge, at the SEC's website at </FONT><FONT SIZE=2><I>www.sec.gov</I></FONT><FONT SIZE=2>, at the Canadian securities regulatory
authorities' website at </FONT><FONT SIZE=2><I>www.sedar.com</I></FONT><FONT SIZE=2> and from Thomson. These documents will also be available for inspection and copying at the public reference room
maintained by the SEC at 100&nbsp;F Street, N.E., Washington,&nbsp;D.C. 20549, United&nbsp;States. For further information about the public reference room, call the SEC at
