Ontario Provincial Police said on social media that the rescue began around noon (16:00 GMT) on Sunday after "winds and current moved the ice shelf away from shore" approximately 2km (1.2 miles). The rescue involved two helicopters making multiple trips to pluck people off the shelf as it continued to fracture into more pieces in the Owen Sound, about 200km north-west of Toronto. One member of the group said that he only realised the ice he was fishing on had detached from shore when he noticed that his GPS showed him moving. Members of the rescued group described harrowing moments, with several of them becoming partially submerged in the cold waters as they sought out the thickest ice on the floe, or sheet. "I looked at my GPS. We were moving," fisherman Kevin Fox wrote, identifying himself on Facebook as one of those who were caught up in the incident. "I turned around and saw waves forming behind us." He said that he and several others started running towards a route that they hoped still connected to shore. (BBC)
