    For the full-year 2005:
    - Revenues increased 8%, to $8.70 billion, driven by 12% growth in
      electronic products, software and services.  Operating profit increased
      10%, and operating profit margin increased to 16.8%.
    - Earnings per share were $1.42, compared with $1.54 in 2004. Adjusted for
      discontinued operations and one-time items, underlying earnings per
      share were $1.43, up 17% from $1.22 in 2004.
    - The corporation generated net cash from operations of $1.88 billion.
      Free cash flow increased 17%, before a one-time withholding tax payment
      of $125 million resulting from the repatriation of profits of
      subsidiaries.  Including the tax payment, free cash flow rose 6% to
      $1.19 billion.

    For the fourth quarter of 2005:
    - Revenues were $2.43 billion, up 5% from the prior-year period,
      reflecting stronger organic growth and contributions from acquisitions.
      Excluding currency effects, revenues rose 6%.
    - Operating profit was $555 million, up 14% from the fourth quarter of
      2004.  Operating margin was 22.9%, up from 21.1% in the prior-year
      period due to higher revenue and greater efficiencies.
    - Earnings attributable to common shares were $249 million, or $0.38 per
      share, compared with $437 million, or $0.67 per share, in the prior-year
      period.  Adjusting for discontinued operations, one-time items, and
      quarterly tax rate normalization, underlying earnings were $402 million,
      or $0.62 per share, compared with $318 million, or $0.49 per share, in
      the fourth quarter of 2004.  One-time items affecting quarter-over-
      quarter comparisons included recognition of gains within discontinued
      operations, primarily in 2004, and the withholding tax payment in 2005.

Thomson's President and Chief Executive Officer, Richard J. Harrington, said, "Our strong results reflect the increasing momentum in our business and the success of our strategic shift to providing integrated workflow solutions to professional customers. Thomson drove revenue and profit growth across all our market groups, a 17% increase in adjusted earnings per share and strong free cash flow growth. We are particularly pleased with the acceleration in the growth of our electronic products, software and services business, which achieved a 12% increase in revenue for the full year and now makes up nearly 70% of our total revenue. We also broadened the range of products and services we offer to our customers through organic development and investment of approximately $289 million in tactical acquisitions in 2005.

"In line with our commitment to drive shareholder value, Thomson returned more than $750 million to shareholders in 2005 through dividends and share repurchases. Given the significant cash flow generation capabilities of our business, our strong balance sheet, and our focus on returning capital to our shareholders, our Board of Directors has accelerated the timing of its annual dividend review to the first quarter of the year and has authorized a 10% increase in the annual dividend rate.

"As part of our commitment to drive growth and returns by optimizing our portfolio of businesses, we are also announcing the sale of four businesses that are not core to Thomson's workflow solutions strategy. The sales will improve the strategic focus and financial profile of Thomson. All of these businesses have solid operations and well-respected brands. We expect these sales to be completed in 2006.

"Looking ahead, we believe we are well positioned to continue to drive organic revenue growth, while expanding margins and growing free cash flow."

      profit margin expanded 70 basis points to 28.1%.
    - Revenue growth in 2005 reflected an 11% increase in online products,
      primarily driven by Westlaw, Checkpoint and international online
      services.  North American Legal achieved growth in all of its major
      market segments, driven by new sales and higher retention.  Revenue from
      sales of software and services increased 14% reflecting growth from
      acquisitions, as well as strong growth at FindLaw and tax and accounting
      software products.
    - Fourth-quarter 2005 revenues grew 6% to $974 million and adjusted
      operating profit increased 10% to $308 million.

      operating profit also increased 7% to $350 million.  Adjusted operating
      profit margin increased 10 basis points to 15.1%.
    - Revenue growth in 2005 resulted from contributions from newly acquired
      e-testing and corporate e-learning businesses, growth in global higher
      education, including a double-digit increase in custom publishing,
      strong business and economic textbook sales, and strong international
      sales.  Revenue growth was also attributable to solid sales growth from
      library reference.
    - In the fourth quarter, revenues grew 2% to $654 million, and adjusted
      operating profit increased 5% to $139 million.  Revenue growth in the

      compared with 2004.

      adjusted operating profit increased 14% to $334 million.  Adjusted

    - Revenue growth for the full year continued to reflect the success of key
      offerings, as well as improved market conditions.
    - TradeWeb's revenues, in particular, increased significantly due to
      higher volumes for its online fixed income marketplaces as a result of
      greater online trading activity and the introduction of new asset
      classes.
    - During the year, the number of Thomson ONE workstations increased 45%
      due to user migration from legacy products and new client sales.

      the prior-year period and adjusted operating profit increased 20% to
      $109 million.  Excluding currency effects, revenues grew 5% in the

      adjusted operating profit increased 21% to $235 million.  Adjusted
      operating profit margin rose 130 basis points to 23.1%, due to higher
      revenues and benefits from integration efforts associated with recent
      acquisitions.
    - Revenue growth for the full year came mostly from acquisitions,
      primarily IHI, and further expansion of information solutions offerings.
      Revenue growth from existing businesses was primarily a result of higher
      customer spending for healthcare decision support products and higher
      subscription revenues for ISI Web of Science and Micromedex electronic
      products.
    - In the fourth quarter of 2005, revenues grew 11% to $312 million, and
      adjusted operating profit increased 10% to $109 million.

    Discontinued Operations

In December 2005, Thomson approved the sale of American Health Consultants (AHC), a medical newsletter publisher and provider of medical education. The results of this business have been reclassified to discontinued operations. Previously, these operations were included in the Thomson Scientific & Healthcare market group. In 2005, AHC generated $35 million in revenue.

Planned Sale of Businesses

In January 2006, Thomson approved the sale of three businesses in the Thomson Learning group, including Peterson's, a college preparatory guide; the U.S. operations of Thomson Education Direct, a consumer-based distance learning career school; and K.G. Saur, a German publisher of biographical and bibliographical reference titles serving the library and academic community. The financial results of these businesses are included in Thomson Learning for 2005 and will be reclassified as discontinued operations beginning in the first quarter of 2006. The combined annual revenues of these three businesses are approximately $145 million.

Dividend

Thomson also announced today that its Board of Directors has authorized an increase of 10%, or $0.08 per share, in the annualized rate of the company's common stock dividend, to $0.88 per share. The new quarterly dividend rate of $0.22 per share is payable on March 15, 2006 to common shareholders of record as of February 21, 2006. In addition, the Board announced that it has moved its annual dividend review from the second quarter to the first quarter of each year. The increase in the dividend rate corresponds to Thomson's objective of increasing the rate in line with increases in free cash flow.

Share Repurchase Activity

During the fourth quarter of 2005, Thomson repurchased $127 million of its shares. During the full year 2005, Thomson repurchased $256 million of its shares. Since initiating its share repurchase program (Normal Course Issuer Bid) in the second quarter of 2005, Thomson has purchased and retired a total of more than 9 million shares.

2006 Outlook

For the full year 2006, Thomson expects revenue growth of 7% to 9%, excluding currency effects, in line with the company's long-term revenue growth target. Full-year 2006 revenue growth will continue to be driven primarily by existing businesses, supplemented by tactical acquisitions.

Thomson expects continued improvement in its operating profit margin in 2006.

Thomson also expects to continue to generate strong free cash flow in 2006.

Note: The Corporation's financial statements are prepared in accordance with Canadian generally accepted accounting principles (GAAP) and are reported in U.S. dollars. When applicable, prior periods are restated for discontinued operations. Adjusted operating profit, free cash flow and adjusted earnings from continuing operations are used by Thomson to measure the Corporation's and its segments' performance but do not have any standardized meaning prescribed by GAAP and therefore are unlikely to be comparable with the calculation of similar measures used by other companies, and should not be viewed as alternatives to operating profit, operating profit as a percentage of revenues, net earnings, cash flow from operations or other measures of financial performance calculated in accordance with GAAP. We reconcile non- GAAP financial measures to the most directly comparable GAAP measure in the following tables. Adjusted operating profit is defined as operating profit before amortization of identifiable intangible assets. We use this measure because we do not consider such amortization to be a controllable operating cost for purposes of assessing the current performance of our businesses. We also use adjusted operating profit margin, which we define as adjusted operating profit as a percentage of revenues. We evaluate our operating performance based on free cash flow, which we define as net cash provided by operating activities less additions to property and equipment, other investing activities and dividends paid on our preference shares. We use free cash flow as a performance measure because it represents cash available to repay debt, pay common dividends and fund new acquisitions. We present our earnings attributable to common shares and per share amounts after adjusting for non- recurring items, discontinued operations, and other items affecting comparability, which we refer to as adjusted earnings from continuing operations and adjusted earnings per common share from continuing operations. We use these measures to assist in comparisons from one period to another. Adjusted earnings per common share from continuing operations do not represent actual earnings per share attributable to shareholders.

The Corporation no longer reports adjusted EBITDA but will continue to report depreciation expense for each of its market groups, as set forth in the attached tables. Segmented results include the results of all operations. Prior to 2005, segmented results were presented on the basis of ongoing businesses, which excluded disposals. Disposals are businesses sold or held for sale, which did not qualify as discontinued operations. Results for the full year of 2005 were reclassified to present disposals within the appropriate market group.

This news release, in particular the section under the heading "2006 Outlook" includes forward-looking statements, such as the Corporation's expectations and intentions regarding its financial performance and strategy, that are based on certain assumptions and reflect the Corporation's current expectations. These forward-looking statements are subject to a number of risks and uncertainties that could cause actual results or events to differ materially from current expectations. Some factors that could cause actual results to differ materially from current expectations are: actions of our competitors; failure of our technology investments to increase our revenues or decrease our operating costs; failure to fully derive anticipated benefits from our acquisitions; failure to develop additional products and services to meet customers' needs; failures or disruptions of our electronic delivery systems or the Internet; failure to meet the challenges involved in expanding outside North America; increased use of free or relatively inexpensive information sources; failure to obtain certain information through licensing arrangements and changes in the terms of our licensing arrangements; changes in the general economy; inadequate protection of our intellectual property rights; an increase in our effective income tax rate; and impairment of our goodwill and identifiable intangible assets. Additional factors are discussed in the Corporation's materials filed with the securities regulatory authorities in Canada and the United States from time to time, including the Corporation's annual information form, which is also contained in its annual report on Form 40-F for the year ended December 31, 2004. 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.

    Notes to consolidated statement of earnings
    (1) "Equity in net losses of associates, net of tax" has been reclassified
        to "Net other (expense) income" in the previous period to conform to
        the current period's presentation.
    (2) Adjustment to reflect income taxes based on the estimated full-year
        effective tax rate of the consolidated group.  Reported earnings for
        interim periods reflect income taxes based on estimated effective tax
        rates of each of the group's jurisdictions.  The adjustment
        reallocates estimated full-year income taxes between interim periods,
        but has no effect on full-year income taxes.

    Note to consolidated balance sheet
    (1) Certain non-current assets have been reclassified in the previous
        period to conform to the current period's presentation.  Specifically,
        capitalized software developed for internal use and for sale is now
        presented separately. Additionally, capitalized costs to create the
        initial version of a textbook or other media ("pre-publication costs")
        are included in "Other non-current assets".  Previously, capitalized
        software developed for internal use and pre-publication costs were
        included in "Property and equipment" which is no longer included on
        the balance sheet.  These reclassifications were made to provide
        additional disclosure on the nature of the assets.
