A 60-year-old man is dead, and a man and a woman in their 30s are in critical condition in the hospital following a head-on collision involving two vehicles in Saint-Lin-Laurentides, in the Lanaudière region. Provincial police were called to Route 335 around 6 a.m. Saturday. Sûreté du Québec (SQ) said the vehicle carrying the two people veered out of its lane and collided with the vehicle driven by the 60-year-old man traveling in the opposite direction. The 60-year-old man was pronounced dead at the hospital. The man and woman in the other vehicle were also taken to the hospital with life-threatening injuries. The male driver of that vehicle was arrested on suspicion of impaired driving. Police say Route 335 remains closed as investigators work to determine the circumstances surrounding the collision.
