Donald Trump Threatens To Rename Lake Ontario ‘Lake America’ Amid Escalating Trade War With Canada

US President Donald Trump said Tuesday, August 25, that the United States is giving “serious consideration” to renaming Lake Ontario “Lake America,” linking the proposal to the worsening trade dispute with Canada. Trump made the remark on Truth Social as Washington and Ottawa moved closer to a broader trade confrontation following the collapse of recent negotiations.

“The United States is giving serious consideration to changing the name of Lake Ontario to Lake America in that we don’t expect to doing much business with Ontario any longer,” the Republican president wrote on Truth Social on Tuesday morning. “Thank you for your attention to this matter!” The proposal is the latest in a series of naming moves associated with Trump, who previously ordered the Gulf of Mexico to be called the Gulf of America in US government usage. Why Donald Trump and Doug Ford Are Trading Insults Amid Ongoing US-Canada Tariff Standoffs.

Donald Trump Threatens To Rename Lake Ontario ‘Lake America’

Lake Ontario And Its History

One of the five Great Lakes, Lake Ontario lies along the US-Canada border, with Ontario province to its north and New York state to its south. The lake is part of the Great Lakes system, which contains roughly one-fifth of the world's surface fresh water.

Its name is derived from the Huron word “Ontarí’io,” generally translated as “beautiful water.” Any official change to the name would have implications beyond the United States because the lake is a shared geographic feature between the two countries. US-Canada Trade War: Donald Trump Announces 50% Tariffs on Autos and Steel From January 2027.

Trade Talks Collapse, Tariffs Rise

Trump's comments came after a difficult week in US-Canada relations. Trade negotiations broke down late last week, followed by new US tariffs on Canadian goods.

The United States imposed 50 percent tariffs on about USD 20 billion worth of Canadian imports over the weekend. Canada is preparing retaliatory measures, with Prime Minister Mark Carney previously saying counter-tariffs would take effect on September 8.

Trump also announced Monday that tariffs on Canadian cars, trucks, automotive parts and steel would rise to 50 percent from January 1, 2027. The move would add pressure to an already integrated North American automotive supply chain.

Trump And Doug Ford Trade Barbs

The dispute has also produced increasingly sharp exchanges between Trump and Ontario Premier Doug Ford. Ford has criticised Trump over the tariffs and called the US president a “bully” and a “dictator.” Trump has responded by attacking Ford and referring to him as a “flunky.”

Ontario is Canada's most populous province and a major centre of the country's automotive industry, making it particularly important to the current trade dispute.

Trump’s Earlier Naming Moves

Trump has previously sought to change the official US terminology for prominent geographic features. Last year, he ordered the federal government to use “Gulf of America” instead of “Gulf of Mexico” in official US contexts. He also restored the name Mount McKinley for Alaska's highest peak, reversing the federal use of Denali.

The latest Lake Ontario proposal, however, remains a statement of intent rather than an announced formal renaming. No US government process establishing “Lake America” as the new name was announced alongside Trump's post.

Canada-US Relations Under Pressure

The latest dispute extends beyond tariffs. Trump has repeatedly argued that Canada should become the 51st US state, a position rejected by Canadian leaders.

Vice President JD Vance also referred to Canada as a “state” during a speech Monday before correcting himself, saying it was a “Freudian slip.” With trade negotiations stalled and retaliatory tariffs pending, the proposed “Lake America” name adds another contentious element to relations between the two long-standing allies.
