The majority of Thomson'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 divided his estate between his three children. His son, Taylor Thomson's father, Kenneth, inherited 42 percent. His two daughters, Audrey and Irma, received 33 percent and 23 percent, 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.

As one of Kenneth Thomson's three children, Taylor Thomson got 14 percent of Woodbridge's assets, as did her brothers David K. R. Thomson and Peter Thomson. Each of Audrey's three children, Linda Campbell, Gaye Farncombe and Susan Grange, own 11 percent. Sherry Brydson, the only child of Irma, holds the largest stake, at 23 percent, according to the source. Billionaire James Pattison, a friend of Kenneth Thomson, told Bloomberg News in a 2012 interview that the magnate, who died in 2006, said he wanted to divide his fortune among his children, and that Kenneth's siblings and their children also had inherited portions of the fortune that originated with Roy Thomson.

Woodbridge's biggest asset is a 64 percent stake in publicly traded Thomson Reuters, a competitor of Bloomberg News and its parent, Bloomberg LP. About a third of the family's assets are held outside of Thomson Reuters and also are managed by Woodbridge. The value of the company's unlisted holdings is derived from a 2007 figure disclosed to Thomson Reuters investors. 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 spokesperson at Thomson Reuters, said Thomson declined to comment on her net worth.


Family: Divorced, 1 child

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. 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 U.K., he sold shares in a public offering in 1965, with his son Kenneth taking over the business in 1976.

One of Kenneth's three children, Taylor Thomson was raised in Toronto, later splitting time in London and the Los Angeles area, where she found modest success as an actress in the 1990s. Her roles included supporting parts in an episode of the television series Forever Knight and the short-lived TV drama Matrix, as well as in a video game, Privateer 2: The Darkening.

She met New York native Michael Kolesa at a Buddhist retreat in upstate New York in the late 1990s, according to a report by Maclean's magazine. The pair married and had a daughter, divorcing after about a year, according to the Canadian publication. Thomson won custody of the child and later returned to Toronto. According to court and published accounts, Thomson began collecting art in the 2000s. She outbid Ann Getty for a pair of Louis XV vases at her first auction, only to learn later that they were frauds. She lost a lawsuit over the purchase against auctioneer Christie's.

Thomson received attention when it was disclosed she had hired private investigator Anthony Pellicano and others to spy on Kolesa and Pamela Miller, a woman who served as a nanny for Thomson in Malibu, California, for about a year. Thomson has sued Miller five times for violation of a non-disclosure agreement.
