Lake Ontario to Lake America: Can Trump rename it?

August 27, 2026

President Trump has proposed renaming Lake Ontario to "Lake America," sparking questions about whether he has the authority to make such a change. The lake, which is one of the five Great Lakes, forms part of the international border between the United States and Canada. The proposed name change has raised concerns about diplomatic relations and the practical implications of unilaterally renaming a body of water that is shared between two sovereign nations.

Who is affected

Canada (as a nation sharing Lake Ontario)
The United States
President Donald Trump
Communities and residents living along Lake Ontario's shores in both countries
International organizations and agencies that use standardized geographical names

Why it matters

This matters because Lake Ontario is an internationally shared body of water between two sovereign nations, making any unilateral renaming attempt a potential diplomatic issue that could strain US-Canada relations. The proposal raises important questions about presidential authority over geographical naming conventions, particularly for features that cross international borders. It also has practical implications for maps, official documents, navigation systems, and international agreements that reference the lake by its current name.
