Lake Ontario (French: Lac Ontario) is one of the five Great Lakes of North America. It is bounded on the north and southwest by the Canadian province of Ontario, and on the south and east by the American state of New York. Ontario, Canada's most populous province, was named for the lake. In the Wyandot (Huron) language, ontarío means “Lake of Shining Waters”. It is the last in the Great Lakes chain and serves as the outlet to the Atlantic Ocean via the St. Lawrence River.
