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, Taylor Thomson's father, Kenneth, inherited about 42 percent. His two daughters, Audrey and Irma, received about 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 Audrey's three children, Campbell owns 11 percent, as do her sisters Gaye Farncombe and Susan Grange.

Each of Kenneth Thomson's three children, David, Peter and Taylor Thomson, received 14 percent of Woodbridge's assets. 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 60 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 investors. A portion of that sum is disclosed in regulatory filings. The family has collected more than $3 billion in dividend income since the 2007 asset figure disclosure.

David Girardin, a spokesperson for Thomson Reuters and Woodbridge, said the billionaire declined to comment on her net worth.


Family: Married, 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.

While Kenneth ran the family business, Roy's two daughters also inherited large minority stakes in the company. Audrey, Campbell's mother, was the oldest of the children. She married Elwood Campbell, a high school science teacher, and raised their three children in Port Credit, Ontario, a town on the shores of Lake Ontario.

Campbell, with her sisters, gave $30 million to the Centre for Addiction and Mental Health in Toronto, and with her cousin Sherry Brydson they also endowed a downtown YWCA. In 2004, with her mother and sisters, Campbell directed what was then Canada's largest ever donation to a hospital -- $67.5 million over four years -- to support cancer research.
