Lake America Map: Where Is Lake Ontario?
“Lake America” is the proposed new name for Lake Ontario — the Great Lake shared by Ontario, Canada and New York State. Here’s where it is, who borders it, and why the border matters.
Where is Lake Ontario?
Lake Ontario is the easternmost of the five Great Lakes. It sits between the Canadian province of Ontario and the U.S. state of New York. Its northern and western shores are in Canada, while much of its southern and eastern shoreline is in the United States.
Water from Lake Ontario flows east through the St. Lawrence River toward the Atlantic Ocean.
Why does the border matter?
Lake Ontario is an international body of water. The boundary between Canada and the United States passes through the lake. That makes the proposed “Lake America” name more complicated than renaming a geographic feature located entirely within one country.
Is Lake America in Canada or the United States?
The proposed name refers to the same Lake Ontario shared by both countries.

Would the map actually change?
The geography would not change. What could change is the label placed on the lake. If the U.S. government formally adopted “Lake America” while Canada retained “Lake Ontario,” maps could potentially display different names depending on the government, publisher, platform or region.
