President Donald Trump says the United States is giving “serious consideration” to renaming one of the Great Lakes as relations with Canada’s most populated province sour.
Trump posted on Truth Social Tuesday morning that he’s thinking of changing the name of Lake Ontario to “Lake America.”
“The United States is giving serious consideration to changing the name of Lake Ontario to Lake America in that we don’t expect to be doing much business with Ontario any longer,” he wrote.
He later posted a graphic illustrating a name change.

The Great Lakes — Huron, Ontario, Michigan, Erie and Superior — are a chain of five freshwater lakes that hold roughly one-fifth of the world’s surface fresh water. Lake Ontario, which the province is named after, shares a border with the U.S. state of New York.
Michigan is the only Great Lake that doesn’t border Canada.
The United States and Canada are locked in a trade dispute after Prime Minister Mark Carney suspended trade talks last Friday, accusing the U.S. of trying to introduce last-minute demands that would limit Canada’s ability to make trade deals with other countries and protect its culture and sovereignty.
The U.S. introduced a new round of 50 per cent tariffs on Canadian exports on Saturday, targeting goods worth $28 billion. Canada announced retaliatory measures Tuesday that will go into effect Sept. 8.
Ontario Premier Doug Ford, whose province is home to the country’s auto industry, said Monday that he backs Carney. He also took aim at Trump after the president posted about him on social media.
“I don’t respond to a dictator like President Trump, a bully like President Trump. I’m not going to take any advice off a guy that’s the king of bankruptcies,” Ford said during a news conference, which also heard him say Trump could “kiss my ass.”
“Let’s be clear, I don’t like the guy — simple.”
Ford told CNN’s Wolf Blitzer Tuesday morning “things got a little personal” with Trump on Monday.
He said Trump’s Lake Ontario post was “a lot of rhetoric,” and it’s time to tone it down.
“I want to make a good deal for the American people, a good deal for the Canadians,” he said.
“We’re the two greatest countries in the world. We’re each other’s No. 1 customer and it’s time to get back to the table and let’s negotiate a fair deal because it’s hurting the U.S., it’s hurting Canada and we just want to make sure that we have a fair deal.”
Carney said Monday that Canada will go back to the negotiating table on a trade deal once the United States changes its attitude and stops treating Canada as a subsidiary.
