Note: The ownership percentages set forth herein are based on the 646,033,729 Common Shares and the 181,229,241 Ordinary Shares outstanding as of December 19, 2008, as indicated in the Form F-9/A filed with the SEC by Thomson Reuters Corporation on December 23, 2008.

Explanatory Note

The common shares (the “Common Shares”) of Thomson Reuters Corporation and the ordinary shares (the “Ordinary Shares”) of Thomson Reuters PLC (including Ordinary Shares underlying American Depositary Shares) that are the subject matter of this Schedule 13G include the 439,767,486 Common Shares and 15,375,287 Ordinary Shares (including Ordinary Shares underlying American Depositary Shares) that are the subject matter of a Schedule 13D filed on December 17, 2008 by The Woodbridge Company Limited (“Woodbridge”), which beneficially owns those 439,767,486 Common Shares and 15,375,287 Ordinary Shares (including Ordinary Shares underlying American Depositary Shares).

Thomson Reuters, a unified group operating under a dual listed company (“DLC”) structure, has two parent companies, both of which are publicly listed — Thomson Reuters Corporation, an Ontario corporation, and Thomson Reuters PLC, an English company. Thomson Reuters Corporation and Thomson Reuters PLC operate as a unified group pursuant to contractual arrangements and provisions in their organizational documents. Under the DLC structure, shareholders of Thomson Reuters Corporation and Thomson Reuters PLC both have a stake in Thomson Reuters, with cash dividend, capital distribution and voting rights that are comparable to the rights they would have if they were holding shares in one company carrying on the Thomson Reuters business.

Under the DLC structure, holders of Common Shares and Ordinary Shares ordinarily vote together as a single decision-making body, including in the election of directors, and in that sense have voting interests in Thomson Reuters. Based on the issued share capital of Thomson Reuters Corporation and Thomson Reuters PLC as of December 19, 2008, Woodbridge has a voting interest in Thomson Reuters of approximately 55% and thus is the principal and controlling shareholder of Thomson Reuters.

Woodbridge, a private company, is the primary investment vehicle for members of the family of the late Roy H. Thomson, the first Lord Thomson of Fleet. Prior to his death in 2006, Kenneth R. Thomson controlled Thomson Reuters Corporation (then known as The Thomson Corporation) through Woodbridge. He did so by holding shares of a holding company of Woodbridge, Thomson Investments Limited. Under his estate arrangements, the 2003 TIL Settlement, a trust of which The Bank of Nova Scotia Trust Company (the “Trust Company”) is trustee and members of the family of the late first Lord Thomson of Fleet are beneficiaries, holds those holding company shares. Kenneth R. Thomson established these arrangements to provide for long-term stability of the business of Woodbridge. The equity of Woodbridge continues to be owned by members of successive generations of the family of the first Lord Thomson of Fleet. Under the Kenneth R. Thomson estate arrangements, the directors and officers of Woodbridge are responsible for its business and operations. In certain limited circumstances, including very substantial dispositions of Common Shares by Woodbridge, the estate arrangements provide for approval of the Trust Company, as trustee, to be obtained.

The filing of this Schedule 13G by the Trust Company and The Bank of Nova Scotia (the “Bank”) should not be construed as an admission that either the Trust Company or the Bank is, for purposes of section 13(d) or 13(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the beneficial owner of the 439,767,486 Common Shares and 15,375,287 Ordinary Shares Ordinary Shares (including Ordinary Shares underlying American Depositary Shares) included in this Schedule 13G. The Trust Company has been advised by Woodbridge that there has been no material change in the Thomson family’s beneficial ownership of Common Shares or Ordinary Shares since the amended and restated Schedule 13D filed by Woodbridge on December 17, 2008.

The Trust Company became Trustee in the ordinary course of its corporate trust business and not with any purpose or effect of changing or influencing control of Thomson Reuters.
