MISSISSAUGA — The Ontario government is marking the groundbreaking of Trillium Health Partners’ new Peter Gilgan Mississauga Hospital. Ontario is investing more than $14 billion to build the new 2.8-million-square-foot Peter Gilgan Mississauga Hospital, tripling the size of the existing Mississauga Hospital to help provide health care to an estimated 2.2 million people. The new hospital will become the largest teaching hospital in Canada, will create one of the biggest emergency departments in the province and will include the Shah Family Hospital for Women and Children.

“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 state-of-the-art 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.
“With this groundbreaking, our government is protecting Ontario’s health-care system and ensuring that more people in Mississauga and across Peel Region can connect to convenient care, where and when they need it,” said Sylvia Jones, Deputy Premier and Minister of Health. “This historic investment is another example of how we are investing in the health-care needs of growing communities, to deliver the highest standard of care for generations to come.”
Once completed, the new hospital will include:
- A new 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 across the region
- A brand-new, 24-7 emergency department that will become one of the largest in the province to connect more people to a wide range of emergency and urgent medical care
- 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 (NICU) 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.

Through Your Health: A Plan for Connected and Convenient Care, the Ontario government is expanding and modernizing Ontario’s hospitals, making it faster and easier for people of all ages to connect to the high-quality care they need, where and when they need it.
