Ontario Premier Doug Ford unveiled a large sign on Lake Ontario on August 29, a direct response to President Trump's recent directive to rename the body of water "Lake America." Ford stated that the lake's centuries-old name would remain unchanged within Canada.

Lake Ontario, one of the five Great Lakes, forms part of the border between the Canadian province of Ontario and the U.S. state of New York. The renaming order issued by the U.S. president applies solely to federal usage within the United States and does not compel Canada or international bodies to adopt the new designation. This action has contributed to ongoing tensions between the two countries, which have been strained by stalled trade talks and existing tariffs.
