Confidence rating:

The majority of Brydson's fortune is derived from 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%. Sherry Brydson, the only child of Irma, owns about 23%.

Brydson is calculated in this analysis to own 23% 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 and adjusted to reflect assets held through Westerkirk Capital, dividends, insider transactions, taxes and market performance. The family has collected more than $3 billion in dividend income and share sales since 2007, based on an analysis of company filings and Bloomberg data.

David Ryan, a spokesman for Brydson, said she declined to comment on her net worth.


Family: Unknown, No children

Canada's richest family was set on its path to wealth in 1931, when Roy Thomson acquired a radio station in North Bay, Ontario. Two years later he bought the Timmins Press, a newspaper in Ontario. Within five years, Thomson was Canada's leading newspaper owner. After expanding in the UK, he sold shares in a public offering in 1965, with his son Kenneth taking over the business in 1976.

While Kenneth ran the family business and eventually inherited about a 42 percent ownership in the company, Roy's two daughters also inherited large minority stakes. Roy's older daughter, Audrey, received about 33 percent. Irma got about 23 percent. Kenneth had three children -- David, Peter and Taylor -- who each inherited about 14 percent of Woodbridge. Audrey had three children who each received 11 percent: Linda Campbell, Susan Grange and Gaye Farncombe. Irma had one child: Sherry Brydson.

Brydson was raised in Toronto and attended the University of Toronto where she was news editor of the campus paper, The Varsity. In 1969, she authored a series of three articles on pollution that are credited with sparking the Canadian environmental movement, according to a story in the University of Toronto Magazine in 1999. She graduated in 1970 with a degree in political science and left to pursue a career in journalism in the UK, according to the article.

She later moved to Victoria, British Columbia, and began using a closely held company she owns, Westerkirk Capital, to manage a part of her fortune held under the Woodbridge company. Among its investments: developing hotels with Marriott in Nova Scotia, making Twin Otter aircraft in Vancouver Island through her Viking Air subsidiary, and owning a series of AM and FM radio stations through Vista Radio.

Through the Irma J. Brydson foundation, she has given money to support the Toronto YWCA among other social institutions in Canada.
