Climate change is a deciding factor in record high water levels in the Great Lakes being higher than ever before, a University of Waterloo professor told CTV’s Your Morning on Wednesday. According to government statistics, July water levels for the bodies of water between Canada and the U.S. were at record highs. And this can lead to faster erosion of the coastline and flooding. The flooding this spring and summer along the northern shores of Lake Ontario, the Toronto Islands and some Toronto-area beaches has been particularly troublesome for homeowners and businesses.
As of Wednesday morning, water levels on Lake Ontario at Cobourg exceeded those seen in the historic 2017 flood. According to Fisheries and Oceans Canada, the water level at Cobourg is 75.92 metres above sea level. At its highest in 2017, the level was 75.88 metres above sea level. “We’re approximately 40 centimetres above normal,” Cobourg Mayor John Henderson said. “With the rain we got this week, I expect that 40 centimetres will be higher, approaching 60 centimetres.”
