Trillium Health Partners launches $1 billion campaign for new Mississauga hospital

Trillium Health Partners began foundation work on a major hospital in Mississauga on October 11, 2026. The foundation launched a $1-billion fundraising campaign for the Peter Gilgan Mississauga Hospital, which will replace the existing Mississauga Hospital. To date, the campaign has raised about $600 million, with the goal of raising the remaining $400 million by 2032. The hospital is expected to open in late 2033 or early 2034.

The campaign supports the construction of Canada's largest hospital and the redevelopment of the Gilgan Family Queensway Health Centre, which will more than double its bed capacity. The initiative involves investments from the province and the City of Mississauga, alongside private donors.
