A 67-year-old man and his six-year-old grandson were killed Sunday after their ATV was hit head-on by a pick-up truck.
The crash happened at about 11:30 a.m. on a dirt road in the Passes conservation area north of Alma, Que.
A 27-year-old conservation area worker was driving the truck and was attempting to pass on a hill when he collided with the ATV.
The impact of the crash was so violent that the ATV was severed in two.
The employee was on duty at the time of the crash, according to Radio-Canada.
The boy and his grandfather, both from Alma, were taken to hospital where they were pronounced dead.
The truck driver was treated for minor injuries.
A collision reconstruction expert from the Sûreté du Québec was dispatched to the scene.
Police said the investigation is still ongoing and charges could be laid against the truck driver.
