The search for a missing canoeist in Georgian Bay, near the Grotto, expanded on Friday.
An OPP Aviation Service Helicopter joined the search, along with members of the Emergency Response Team, and the Bruce Peninsula OPP Auxiliary.
The Bruce Peninsula OPP, the OPP Marine Unit, and Bruce Peninsula National Park wardens are also involved in the search.
The 22-year-old man from Queensland, Australia was reported missing around mid-afternoon Thursday when the canoe he was in capsized off Northern Bruce Peninsula.
The other man in the canoe, a 25-year-old from Windsor, was able to swim to shore. He was treated for hypothermia and has since been released from hospital.
Police say the pair were not wearing life jackets.
