FRENCH RIVER, Ont. -- Police divers are searching for a man who disappeared after the canoe he was in capsized in a provincial park in central Ontario.

Investigators say two men and a 10-year-old boy were in a canoe that tipped over Sunday at Recollet Falls in French River Provincial Park.

Police say the men were trying to negotiate the quick-moving water when the canoe went over, throwing all three occupants into the river.

One of the men and the boy -- both of whom were wearing life-jackets -- were pulled from the water by other people in the area.

Police say the other male, who was not wearing a life-jacket, has not been found.
