Lake Ontario surrounded on the north by Ontario. It is one of the five Great Lakes of the North America. The name of the lake is derived from Skanadario, an Iroquois word meaning either “beautiful lake” or “sparkling water.” The lake has a natural charming rhythm of eleven minutes. The attractive effect normally is about 2 centimetres (3/4 inches) but can be greatly blown up by earth movement and winds. Because of its great depth, the lake rarely freezes in winter. The winters of 1934 and 1976 were the only times the lake had ice cover within its history.
