Over the past few years, Canada has emerged as a hub for single-family offices. Many Canadian millionaires and billionaires have launched their private investment firms and begun actively investing in both private and public markets. In the following, we are introducing you to three interesting Canadian family offices from our list.

1. Westerkirk Capital (Toronto)

Sherry Brydson is known for maintaining a low public profile, with limited information available about her personal life and investment activities. She consistently declines interview requests, contributing to her reputation as one of Canada’s most private billionaires. Her family office, Westerkirk Capital, is based in Toronto and focuses on investments in hospitality, aviation, and real estate. Through Westerkirk, Brydson owns Viking Air in British Columbia, which produces a modernized version of the Twin Otter aircraft for a global market. The firm’s portfolio also includes the Moose FM radio network in Ontario and a hotel development company in Nova Scotia. In addition, Westerkirk Capital has pursued investments in real estate as well as oil and gas.
