Construction has begun on the Stevenson Memorial Hospital expansion in Alliston, Ontario. The province’s $174-million investment will increase inpatient bed capacity by 20 per cent and add a new emergency department triple the size of the current space.

The redevelopment will also bring expanded diagnostic and surgical services, a new three-storey building, and a birthing suite, with completion slated for 2028.

“Our new hospital expansion will transform Stevenson into a modern, state-of-the-art facility, enhancing the health-care services and space our growing community needs and deserves today and for future generations,” said Carmine Stumpo, the hospital’s supervisor. “We are thankful for all our partners, donors, staff and physicians, and local municipal and provincial governments, for their unwavering support.”

Canadian construction company Pomerleau Inc. was awarded the building contract on January 30, 2026. The healthcare facility currently offers 38 inpatient beds and outpatient services to communities, including Adjala-Tosorontio, Canadian Forces Base Borden, Essa, Innisfil and New Tecumseth.
