Stevenson Memorial Hospital (SMH) and the Ontario government announced on Friday that a contract was awarded to Pomerleau Inc. to build the new state-of-the-art healthcare facility next to the existing hospital.

The $174 phase one redevelopment contract is funded by provincial investment. SMH said in the news release that it is the step that gives the ‘green light’ for construction to start in the coming weeks.

“We look forward to working closely with Pomerleau Inc. as we build a new hospital facility for Stevenson and a new future, transforming health care for New Tecumseth and surrounding communities,” said Carmine Stumpo, SMH Supervisor, in the news release.

According to SMH, the current infrastructure on Fletcher Crescent in Alliston was designed to support 7,000 emergency department visits per year when it was built in 1964. The hospital says it now manages nearly 35,000 visits per year.

With the construction of the new facility, the hospital size will double to more than 147,000 square feet and the emergency department size will triple, with ‘modern, comfortable’ spaces for patients, visitors and staff.

It will also include an expanded medical/surgical inpatient unit with 100 per cent single-occupancy patient rooms, expanded diagnostic imaging suites with brand new equipment (including SMH’s first MRI suite), a new obstetrics unit and new ‘state-of-the-art’ surgical suites.

“Our government is making historic investments to protect Ontario’s health-care system and connect more people to the care they need, where and when they need it,” said Sylvia Jones, Deputy Premier and Minister of Health, in a news release. “By investing in the redevelopment of Stevenson Memorial Hospital, we are making it faster and easier for more people and their families to access world-class hospital care in their community, for generations to come.”

The province says the complete redevelopment is expected to be completed by late 2028.
