Trillium Health Partners – Legacy Stories
Merging hospitals is rarely easy. Merging three, each with proud histories, passionate stakeholders, and large service footprints, is harder still. But that’s what Trillium Health Partners accomplished; first through a provincially mandated merger in 1998, then by choice in 2011.
StrategyCorp played a critical role in the second, voluntary merger: the creation of Trillium Health Partners (THP) as it exists today.
In 2011, Trillium Health Centre and The Credit Valley Hospital began exploring closer collaboration. Unlike the 1998 forced merger of Mississauga Hospital and Queensway General Hospital (which formed Trillium Health Centre), this time the institutions led the process themselves. What made the merger particularly complex was the deep attachment communities had to their hospitals. Years of local fundraising, volunteer engagement, and care experiences had built fierce loyalty. For many, losing a hospital’s identity felt like losing a part of their neighbourhood.
The challenge wasn’t just operational – it was political. Doctors, nurses, family physicians, and donors all had concerns about what the future state would mean for them. StrategyCorp worked closely with both institutions to shape a strategy that acknowledged those anxieties while framing the merger as a bold step toward delivering care for a growing region for the future.
The firm supported stakeholder engagement, narrative development, and issue navigation, helping the hospitals speak with one voice. They emphasized shared values, seamless patient care, and the opportunity to build a more integrated, academic health system. That framing landed.
By December 1, 2011, the two institutions were legally merged. The following year, the new brand, Trillium Health Partners, was launched, along with a strategy built around the theme of “Better Together.”
Today, THP is one of Canada’s largest community-based, academically affiliated hospitals. It operates three sites: Mississauga Hospital, Queensway Health Centre, and Credit Valley Hospital, and serves over one million people in Mississauga and West Toronto. It houses the country’s largest emergency department and is in the midst of delivering Trillium HealthWorks, the most significant hospital infrastructure renewal project in Canadian history.
From early tensions to a nationally admired health system, the Trillium story is a model for thoughtful, community-first hospital integration. And at its most delicate moment, when the risk of failure was real, StrategyCorp helped bridge the politics, protect the legacy, and align interests around a common goal: building a healthier, better-served community.
