What Is the Origin of the Name "Ontario"?

The province of Ontario is one of the 10 provinces and three territories that make up Canada.

"Beautiful Lake"

The word Ontario originates an Iroquois word meaning "beautiful lake," "beautiful water," or "big body of water," though experts remain uncertain about the precise translation of the word. The water-based origin of Ontario's name is appropriate, given there are more than 250,000 lakes in the province, making up about a fifth of the world's fresh water.

Naturally, the name first referred to Lake Ontario, the easternmost of the five Great Lakes. It is also the smallest Great Lake by area. In addition, all five of the Great Lakes share a border with the province. Initially called Upper Canada, Ontario became the name of the province when it and Quebec separated in 1867.
