An 18-year-old man is dead after his motorcycle struck a vehicle near the junction of highways 440 and 15 in Laval.

Sgt. Claude Denis of the Sûreté du Québec said witnesses reported seeing the motorcycle travelling very fast just before the crash. 

"The driver of the motorcycle was ejected and transported to hospital and, unfortunately, his death was pronounced at 1:30 a.m.," he said.

Two occupants of the other vehicle were taken to hospital for treatment of minor injuries. 

Highway 440 was closed until around 4 a.m. as police investigated.
