Private family foundation serving Ottawa and Southern New Brunswick. The Crabtree Foundation funds registered Canadian charities and supports charitable work in education, health, arts, the environment, and community/family support through multiple grantmaking decisions each year. View The Harold Crabtree Foundation's website for more information.

The Crabtree Foundation is a private family foundation based in Ottawa, Ontario. It operates as a discretionary grantmaker, using endowment income contributed by family members to support registered Canadian charities. Its public pages show both its grantmaking purpose and a substantial history of giving.
The foundation’s stated interests include community and family support through education, health, arts, and the environment. Its geographic scope is principally Ottawa, Ontario and Saint John, New Brunswick.
The website says the foundation does not accept unsolicited applications and does not solicit donations from non-family members. Instead, it distributes grants from its endowment on a yearly board cycle, with funding decisions made in November and inquiry letters due by September 30.
Published grant history demonstrates sustained support for a wide range of organizations, including universities, health charities, cultural groups, social-service providers, environmental organizations, and community agencies. The site reports more than $63.7 million in cumulative grants and a large number of recipients in a single year, confirming an active philanthropic role rather than an internal-only foundation.
The foundation traces its origins to Harold Crabtree, who established The Harold Crabtree Foundation in 1951 for general charitable purposes. The site notes that later generations of the Crabtree family continue to manage the foundation and carry forward its tradition of charitable giving.
