Redefining the future of health care

In February 2022, the Peter Gilgan Foundation made an historic $105 million gift to Trillium Health Partners (THP) – the largest donation to a hospital in Canadian history. The donation will support THP in building the largest and most advanced hospital in Canada, to be named “The Peter Gilgan Mississauga Hospital.” It will also help expand and redevelop Queensway Health Centre, which will be named “The Gilgan Family Queensway Health Centre.”


The new Peter Gilgan Mississauga Hospital will replace the existing 62-year-old facility, and a new patient tower at Queensway Health Centre will be home to needed complex care and rehabilitation services. These projects represent the largest capital build in Canada’s history and will add more than 600 beds across the organization, for a total of almost 2,000 beds, to accommodate the incredible growth in this community, making THP the largest hospital in Canada.


Construction on the new Peter Gilgan Mississauga Hospital is expected to start in 2025 with the Queensway Health Tower construction expected to begin in 2024.


“As the community has grown and diversified, so have the demands on the hospital. The additional struggles presented by the pandemic have underscored the critical need for modern healthcare facilities, and challenged our healthcare workers like never before. 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 the business in this region many years ago, this gift is a way of giving back to the community and to recognize our amazing healthcare workers for their commitment. I’m thrilled to be able to support THP in its much-needed mission to transform healthcare.”

Peter Gilgan is the most generous benefactor to health care in Canadian history, and we could not be prouder that he and his family have chosen Trillium Health Partners as the recipient of this extraordinary donation. 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."

– Caroline Riseboro, President & CEO, Trillium Health Partners Foundation


"We serve one of the fastest growing and most diverse populations in Canada and have been challenged with an unprecedented demand for care. Adding to this pressure, during the pandemic, our community has been the hardest hit. THP's unwavering commitment is to solve these challenges through innovation and high performance. On behalf of our community and THP's dedicated team of staff, professional staff, volunteers and learners who work hard to provide exceptional care each and every day, we are so grateful to Peter Gilgan and The Peter Gilgan Foundation for playing such an instrumental role in supporting our vision and helping to build new infrastructure that creates a more complete, efficient and equitable health system."
