Three people are dead after a one-car collision north of Renfrew Sunday morning.

Police are still trying to find out what caused the car to leave the road and rollover into a ditch along Forresters Falls Road near Highway 17.  There were four people in the car at 9:15 a.m. when the collision took place.

The male driver and a teenaged girl died at the scene. The two other passengers were taken to Renfrew Victoria Hospital, and one later succumbed to their injuries.

Police say they will not release the names of the victims until notifying relatives.
