Provincial police say two people are in hospital following a collision north of Peterborough between a plane and a barge from a children's camp.

Police say a float plane attempting a takeoff collided with a barge at Gannon's Narrows between Pigeon Lake and Buckhorn Lake.

There were seven people, but no young children, on the barge from Camp Maple Leaf and the pilot was the only occupant of the plane at the time of Monday afternoon's collision.

The pilot —a 72-year-old Toronto man — and a 17-year-old female camp staff member were taken to Peterborough Regional Health Centre.

Police say the teen's injuries are non-life threatening.

On Tuesday, the OPP identified the pilot as Roy Crocker and reported that he remained “in grave condition” in an intensive care unit.

The Transportation Safety Board has been notified and an investigation is ongoing.
