A pickup truck crashed into Hôtel-Dieu Grace Hospital's satellite kidney dialysis unit on McDougall Street on Thursday night.
Hospital spokesperson Steve Erwin said the unit will be open for patients Friday, but they'll have to use the rear entrance.
The Freschco grocery store was also damaged.
Windsor Police are investigating.
A handful of staff and patients were there when a pick-up truck crashed into the building around 9 p.m. No one was hurt and none of the medical equipment was damaged.
"It's very fortunate no one was injured. There were staff inside the building at the time. They were discharging the last patients for the evening," Erwin said. "The truck happened to smash into the unit in the front entrance area and didn't damage anywhere where the patients and staff were inside."
Erwin said it's important the treatments are not disrupted.
"These are very medically necessary treatments. Someone with kidney issues require these dialysis treatments two, three, four times a week," Erwin said.
Erwin says a thorough check of the building was made.
"We wanted to make sure the unit was safe for patients to enter. obviously, so we'll be using a rear entrance to allow patients to get in to get their treatments," he said.
Police say a 70-year-old man suspected of driving drunk was arrested and taken to police headquarters for a breathalyser test.
