Helping build Canada’s largest hospital with Canada’s largest donation

February 15, 2022

Peter Gilgan Foundation is proud to announce a $105 million donation to Trillium Health Partners (THP) as they embark on two facility revitalizations that reimagine health care for the western GTA region and beyond.

The donation is the largest to a hospital in Canadian history and pushes the threshold of philanthropy to an unprecedented level.  

With funds going towards the Peter Gilgan Mississauga Hospital and the Gilgan Family Queensway Health Centre, THP’s already impressive network of campuses will swiftly establish a new and lasting standard of care for the country.

THP will combine bold new infrastructure with a proactive approach to community health – it’s the complete solution we urgently need. And because I started my business in this region many years ago, this gift is a way of giving back to the community and to recognize our amazing health care workers for their commitment.

The comprehensive and innovative health care services this investment will provide for patients, and their families, is enormously progressive. Trillium Health Partners is enabling its incredible team of health care professionals to continue delivering the highest quality of care, in facilities to match their standard.

Peter Gilgan Foundation is extremely honoured to be part of this historic moment in Canadian health care, and hopes a ripple effect of support for this visionary hospital will spread far and wide.

Peter’s unparalleled generosity embodies the power of philanthropy to help transform health care and will inspire others to step up so THP can realize its bold vision of a new kind of health care for a healthier community.
