The majority of Campbell's fortune is controlled by Woodbridge, an investment firm that manages the family fortune originated by Canadian media magnate Roy Thomson. After his death in 1976, Thomson's estate was divided between his three children. His son, Kenneth, inherited 42% and his two daughters, Audrey and Irma, received 33% and 23%, respectively, according to a person familiar with the family's assets who asked not to be identified because Woodbridge is closely held.

Each heir evenly split their share in Woodbridge among their children, the source said. David and his two siblings, Peter and Taylor, each received 14% of Woodbridge. Each of Audrey's three children, Linda Campbell, Susan Grange and Gaye Farncombe, received 11%. A cousin, Sherry Brydson, the only child of Irma, owns about 23%.

Campbell is calculated in this analysis to own 11% of Woodbridge's stake in Thomson Reuters and it's Cash & Other Assets.

Woodbridge owns 67% on Thomson Reuters, according to a February 2022 filing.

Cash & Other Assets is based on Woodbridge asset values as disclosed in a 2007 investor presentation 2007 and adjusted to reflect dividends, insider transactions, taxes and market performance. The family has collected more than $3 billion in dividend income and share sales since then, based on an analysis of company filings and Bloomberg data.

David Girardin, a spokesman for Thomson Reuters, didn't respond to requests for comment.
