Trump signs order renaming Lake Ontario as ‘Lake America’ in U.S.

U.S. President Donald Trump said on Thursday (August 27, 2026) that he is renaming Lake Ontario to be known as “Lake America” in the United States as he exacerbates his trade war with Canada.

The Republican President signed an executive order that updated the lake’s name for the U.S. geographic naming service. Mr. Trump cannot force Canada to follow his preferred naming convention, however.

Mr. Trump has been floating the idea of the name change in recent days as the U.S. announced it was imposing 50% tariffs on $20 billion worth of Canadian goods over the weekend after talks between the countries broke down.

Mr. Trump has been needling America’s northern neighbour since he returned to the White House last year, suggesting the ally with whom the U.S. once had warm relations should instead be absorbed as the 51st state.

Canada responded to Mr. Trump’s import taxes this week by imposing retaliatory tariffs on $20 billion worth of American goods, including steel, dairy products, appliances and farm equipment

Mr. Trump, who signed the order as he was sitting at the Resolute Desk in the Oval Office, had a large sign behind him propped on a stand with a map of the Great Lakes. Over Lake Ontario, in big red letters, the map read “Lake America.”

On the other wide of the President was another map with the words, “MAKING THE GREAT LAKES EVEN GREATER.”

He told reporters that Canada is “the worst” to deal with on trade. “They feel entitled and we can’t have that,” he said.

The office of Canadian Prime Minister Mark Carney did not immediately respond to a request for comment. The lake is one of multiple Great Lakes that the U.S. and Canada share borders along.

The move, which Trump said was “effective immediately,” is reminiscent of his move last year to rename the Gulf of Mexico as the “Gulf of America.’”

Mr. Trump on Thursday (August 27, 2026) suggested his push to rename bodies of water may not be finished.

“So, if you think about it, we have a gulf, and we have a lake. Now, all we need is an ocean,” Mr. Trump said. “So maybe we’ll have to change the name of the Atlantic and or the Pacific. Maybe we’ll change them.”
