History and Background
The roots of the Weston Family Foundation date back to the late 1950s, when Willard Garfield Weston and Reta Howard Weston established the family’s philanthropic foundation.
The Foundation was created using shares from the family company, George Weston Limited, and reflected the founders’ belief that wealth generated through successful Canadian businesses should be used to benefit Canadians.
The Foundation began making substantial charitable donations during the 1960s under the name W. Garfield Weston Foundation.
Its early grants supported medical research, education, cultural institutions and social-service organizations.
One of its earliest significant contributions came in 1960, when it provided a $1 million grant to the Dr. Charles H. Best Foundation to support the Banting and Best Institute at the University of Toronto. This was one of the Foundation’s first major investments in medical research.
During the following decades, the Foundation gradually broadened its grantmaking activities.
Key historical areas of support have included:
- Medical and health research.
- Universities and higher education.
- Nature conservation.
- Museums and cultural institutions.
- Environmental research.
- Canadian northern science.
- Scholarships and student support.
- Sustainable agriculture.
- Community development.
- Food-system innovation.
- Arts, culture and heritage.
In the 1970s and 1980s, the Foundation expanded its environmental and educational giving. It supported organizations including the Toronto Zoo, Multiple Sclerosis Society, Royal Ontario Museum and several Canadian universities.
In 1980, the Foundation established its first educational endowment at the University of King’s College in Halifax. Over time, it provided approximately $17 million in educational endowments across Canada.
During the 1990s, the Foundation increased its involvement in environmental conservation. One important example was its partnership with the Nature Conservancy of Canada on the Waterton Park Front Project, which helped conserve important habitat next to Waterton Lakes National Park.
During the 2000s, the Foundation significantly increased support for northern Canadian research. In 2007, it launched the Weston Family Awards in Northern Research, which became one of its longest-running research programs.
During the 2010s, the Foundation adopted what it describes as a “spark, shepherd, scale” approach to philanthropy. This philosophy focuses on supporting promising ideas at an early stage, helping them develop and then expanding successful approaches capable of achieving wider impact.
Following a two-year strategic review in the early 2020s, the organization changed its name from the W. Garfield Weston Foundation to the Weston Family Foundation. The new name reflects the involvement of several generations of the Weston family in Canadian philanthropy.
The strategic review also concentrated the Foundation’s work around two major areas: Healthy Aging and Healthy Ecosystems.
