Toronto waterfront

The Toronto waterfront is the lakeshore of Lake Ontario in the City of Toronto, Ontario in Canada. It spans 46 kilometres between the mouth of Etobicoke Creek in the west, and the Rouge River in the East.HistoryLake Ontario is a recent lake. As the last glaciation, the Laurentian glaciation receded, a number of proglacial lakes filled in basins adjacent to the glacier. One of those proglacial lakes was Lake Iroquois. Lake Iroquois was considerably deeper than Lake Ontario, as a lobe of the Laurentian glacier still filled the valley of what is now the St. Lawrence River. The southern boundary of Lake Iroquois was the Niagara escarpment. The lake flowed over the Niagara Escarpment east of Rochester, and flowed to the Atlantic Ocean down what is now the Mohawk River, to the Hudson River. The shoreline of Lake Iroquois can be observed in steep hills, such as that on the north side of Davenport Road. Casa Loma has a good view of the harbour, four kilometres away, as it is on the height of the old shoreline.When the glacier retreated from the St Lawrence Valley the shoreline receded to a much shallower level than today's lake, as it takes time for land that had been under a heavy glacier to rebound. This lake was call Admiralty Lake. Some sources suggest the drainage of the lake triggered the Upper Dryas climatic change. Some sources suggest the lake drained all the way to sea level and the lake became brackish.
