Laval police say two pedestrians died Tuesday night in separate collisions less than 90 minutes apart.

In the first collision, which happened around 4:25 p.m., a vehicle struck a 61-year-old man while he was crossing Laurentides Boulevard, near the intersection of Riopelle Street, according to Stéphanie Beshara, a Laval police spokesperson.

The victim was pronounced dead at the scene.

At around 5:50 p.m., police were called to Cartier Boulevard Ouest for another report of a pedestrian being struck.

In that case, a vehicle struck a 37-year-old woman while she was crossing the street, near the intersection of Laurentides Boulevard.

She was sent to hospital in serious condition where she later died of her injuries, according to Beshara. 

The driver, a woman in her late 40s, was treated at the scene for shock.

Both collisions are under investigation.
