The Harry E. Foster Charitable Foundation was established to support organizations working with individuals who have intellectual and developmental disabilities. It aims to empower people with disabilities to lead fulfilling lives and to foster inclusion and participation in all areas of community life. The Foundation carries on the legacy of its founder by working toward greater awareness, support, and opportunities for those with developmental challenges.

The Foundation is based in Toronto, Ontario, and much of its charitable work focuses on Ontario. However, its support has contributed to projects and events that have national reach, such as the founding of research and training centres across Canada and the support of Special Olympics programs involving participants from both Canada and the United States.

Program highlights include providing grants to organizations that serve people with intellectual and developmental disabilities. The Foundation has supported employment training centres, led fundraising campaigns, and helped establish inclusive sports programs like the Canadian Special Olympics. It typically funds projects, not operating expenses, and encourages innovative programs that build skills, promote inclusion, and create opportunities within the community for people with developmental disabilities.
