The Ontario government is marking the groundbreaking of Trillium Health Partners’ new Peter Gilgan Mississauga Hospital.

The province is investing more than $14 billion to build the new 2.8-million-square-foot facility, which will triple the size of the existing Mississauga Hospital and make it the largest teaching hospital in Canada.

“Our government’s investment in the Peter Gilgan Mississauga Hospital is an important part of our more than $200 billion plan to build and protect Ontario,” said Premier Doug Ford. “Today’s groundbreaking means more beds, more doctors and more nurses right here in Mississauga. It also means good-paying jobs today and a stronger health-care system for decades to come.”

Once open, the hospital will bring 2,400 more health-care workers and approximately 400 additional doctors to the community, significantly increasing Trillium Health Partners’ ability to provide more patients and families with timely, high-quality services including cancer care, cardiac surgeries and geriatric mental health resources.

Once completed, the new hospital will include:

• a 22-storey patient care tower with over 350 new fully private beds, bringing the total number of beds to over 950
• nine new and 14 enhanced state-of-the-art operating rooms, increasing surgical capacity and reducing wait times
• a brand-new, 24-7 emergency department that will become one of the largest in the province
• the Shah Family Hospital for Women and Children, which will span over 200,000 square feet and include one of the largest Neonatal Intensive Care Units in the province, designed to deliver specialized, high-acuity care for newborns and their families
• advanced diagnostic imaging facilities
• a new pharmacy, clinical laboratory and improved infection prevention and control measures.

"The Peter Gilgan Mississauga Hospital and Shah Family Hospital for Women and Children represent the future of health-care infrastructure in Ontario,” said Infrastructure Minister Kinga Surma. “Through our progressive P3 model, we are not only building hospitals — we are making good on our promise to deliver resilient, world-class public infrastructure that supports enhanced access and services that make life better for people in their local communities. I’m proud to see this historic project move forward."

The province is supporting additional expansion projects at Trillium Health Partners, including the $1.3 billion contract it signed with EllisDon in April 2024 to build the Gilgan Family Queensway Health Centre in Etobicoke.

Over the next 10 years, Ontario is investing nearly $60 billion on major health infrastructure.
