A City of Ottawa worker has died after he was struck in an incident involving two garbage trucks on Cyrville Road early Monday morning.

Ottawa police confirmed a 55-year-old man was working between the two trucks near Innes Road at about 7 a.m. when a collision occurred. The precise nature of the crash has not yet been released.

"We know that two garbage trucks were involved in a collision. A male was working between the two trucks when he was struck," said Det.-Const. Kevin Bradford.

The city confirmed the man was a City of Ottawa employee from the public works and environmental services department.

Flags at all city sites have been lowered to half-mast, and will remain there until sunset on the day of the memorial service, the city announced Monday afternoon.

'Like losing a member of the family'

"First and foremost, I extend my deepest sympathies to the family, friends and colleagues of our employee. Today is an extremely difficult day for those who are affected by this tragic incident. The city is providing support to its employees through the Employee Assistance Program," said the public works department's acting general manager, Quentin Levesque, in an emailed statement.

Mayor Jim Watson also extended his sympathies.

"Obviously our hearts and prayers go out to his family. To lose a member of our staff is like losing a member of the family," he said.

The worker suffered critical injuries. He was taken to the Ottawa Hospital's Civic campus trauma unit, and was pronounced dead en route.

Police said his family has been notified.
