Lake Frontenac was a proglacial lake in the basin of what is now Lake Ontario. The sudden influx of fresh water into the Atlantic, as the retreat of the Laurentian Glacier triggered a sudden drop in the lake's water level, may in turn have triggered the onset of the Younger Dryas, 1000 year period of renewed cooling approximately 12000 years ago.
