Ontario continues to dominate Canada's rich list.

A standout on the list is The Woodbridge Company, a Toronto-based holding firm for the Thomson family. Six billionaire heirs have stakes in the company, which controls more than 310 million shares of Thomson Reuters — highlighting just how influential the family is.
