BARRIE, ONT. -- Ontario provincial police ramped up their search for a missing canoeist on Sparrow Lake in Gravenhurst, Ont., on Friday with help from the Underwater Search and Recovery Unit divers and the OPP helicopter. Police set up a station at Sopher's Landing one day after 56-year-old Ian Walker went out on the lake near his cottage and never returned. "There was no indication he was going anywhere in particular," said Bracebridge OPP Sgt. Darcy Jibb. Police say the Toronto man's family reported his disappearance on Thursday. They say he went out early Thursday morning in a canoe near Riverview Drive and Severn Bridge.
