A 42-year-old mother and her two kids, a 15-year-old boy and 13-year-old girl, were killed in a major accident involving two vehicles in Saint-Jean-sur-Richelieu in the Montérégie, Que., region Sunday afternoon.
According to provincial police, a pickup truck travelling at a high speed hit the family's car, which was stopped at a red light at the intersection of Boulevard du Séminaire Nord and Boulevard Saint-Luc, around 10:30 a.m.
Following the impact, police said the truck dragged the vehicle for several metres before coming to a stop.
The driver of the pickup, a 65-year-old man, sustained minor injuries and was transported to hospital. He will speak with investigators.
The Sûreté du Québec (SQ)'s major crimes unit has taken over the investigation and have a reconstruction team on scene to determine the cause and circumstances of the collision.
Police said the cause of the crash is still unknown. Alcohol does not appear to be a factor, but speed could have played a role, according to the SQ.
