A 16-year-old boy is in critical condition after falling during a car surfing stunt in a Montreal suburb on Friday.

Witnesses told police the boy fell off the trunk of a car in the parking lot of Jean XXIII school in Dorval and hit his head.

Montreal police Const. Daniel Lacoursière said investigators are talking to the 17-year-old driver of the car, as well as other witnesses.

Lacoursière says the victim's injuries are considered very serious.

Two people were killed in separate car surfing incidents last year in the province and a Quebec City woman was seriously injured after falling off the roof of a truck this month.
