‘Lake America’ appeared on US maps days after Ontario’s premier told Trump to “kiss my ass”
US President Donald Trump has officially renamed Lake Ontario “Lake America” amid an escalating trade war with Canada and Ontario – whose premier recently told him to “kiss my ass” and threatened to cut electricity supplies to the US.
“We’re going to be changing the name of Lake Ontario, effective immediately, to Lake America,” Trump declared in the Oval Office on Thursday before signing an executive order that requires federal agencies to use the new name on government maps, contracts, documents and communications.
The change was swiftly put into effect, with Trump sharing a letter from the US Geological Survey confirming that the federal Geographic Names Information System had already been updated.
The renaming caps a bitter week in which the trade dispute between Washington and Ottawa rapidly descended into personal insults and threats. The confrontation erupted after negotiations collapsed and Washington imposed 50% tariffs on roughly $20 billion worth of Canadian imports.
On Monday morning, Trump threatened to further raise tariffs on Canadian cars, auto parts and steel to 50% from January 2027, accusing Canada of “ripping off” the US and declaring that it would no longer be treated “like a State.”
Ontario Premier Doug Ford responded almost immediately, threatening to withhold or sharply raise the price of oil, potash and uranium exports and saying Ontario was prepared to revive a surcharge on electricity sent to the US, or even cut power exports altogether.
“Someone should get these clowns to ‘fall in line’ or, the consequences for Canada will be far WORSE!” Trump fired back. Ford, who was holding a press conference at the time, doubled down, saying: “I have a lot of real estate on my ass, so he has a lot of room to kiss my ass.”
The following day, Ottawa put financial weight behind the rhetoric. Canada formally unveiled retaliatory tariffs matching Washington “dollar for dollar, rate for rate” on C$27.6 billion ($20 billion) worth of US goods. Duties of 15%, 25% and 50% on products including steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics are due to take effect on September 8.
Prime Minister Mark Carney has insisted that Canadians will continue using the historic name, noting that “Ontario” derives from an Indigenous word predating both countries. New York Governor Kathy Hochul has likewise said her state would not adopt “Lake America.”
Washington cannot force Canada or international organizations to recognize the change, but it can dictate terminology across the US federal government.
On his first day back in office in January 2025, Trump similarly ordered the Gulf of Mexico renamed the “Gulf of America” for federal purposes – and suggested Thursday that another geographic rebranding could be next.
“We have a gulf and we have a lake. Now, all we need is an ocean,” he said, floating either the Atlantic or Pacific as a possible candidate.
