Trump Renames Lake Ontario to "Lake America"

President Donald Trump signed an executive order in the Oval Office on Thursday to officially change the name of Lake Ontario to "Lake America," escalating a high-stakes trade conflict with Canada.

Trump stated during the signing that the rebranding was effective immediately, though the text of the directive allows the Department of the Interior and the Board on Geographic Names 30 days to update the Geographic Names Information System. The system serves as the primary federal database for domestic geographic titles in the United States.

When asked about the message behind the order, Trump openly aired grievances over economic ties between the neighboring nations, asserting that Canada "has been ripping us off for a long time on trade". He added:

"Well, they haven’t treated us well. The Canadian officials have treated us very badly. They’re nasty people."

"So the lake change – the Lake of America – was something I’ve been thinking about for a long time, actually."

Teasing further changes, the president hinted that his administration might look beyond lakes and gulfs, stating:

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

The decision follows the collapse of bilateral trade negotiations last week ahead of an August 22nd deadline. In response to the breakdown, Washington imposed 50% tariffs on $20 billion worth of Canadian imports, including timber, alcohol, and apparel, with additional tariffs planned for steel and auto parts in January.

Canada responded by preparing retaliatory duties of up to 50% across roughly 700 American products valued at an equal amount, scheduled to take effect next month. While Canadian US Trade Minister Dominic LeBlanc noted some minor adjustments in negotiations regarding labeling requirements, both governments have largely blamed each other for demanding last-minute changes.

The executive order carries no binding authority over Canada or international organizations, as no global body universally governs water names.

Canadian Prime Minister Mark Carney swiftly dismissed the unilateral move online, highlighting that the name Lake Ontario originates from the Wendat language, meaning "the lake is beautiful, the lake is big", and has been used for more than four centuries. Carney wrote:

"The name is more than 400 years old, predating both the Confederation of Canada and the Declaration of Independence of the United States of America."

"We know that America is changing. Their trading relationships, their foreign policies, their national monuments, their hydronyms. Canadians also know that naming reality means calling it Lake Ontario – then, now and always."

Regional leaders across Canada echoed Carney's sentiments. Ontario Premier Doug Ford said on social media that "It's Lake Ontario to Canadians and the rest of the world. Now and forever," while Nova Scotia Premier Tim Houston said, "We're into some real foolishness now. It's Lake Ontario, buddy."

Opposition also emerged within the US. Democratic Governor Kathy Hochul of New York, which is the sole US state bordering the body of water, clarified that state authorities would not use the new title, writing online, "New York won't be calling it that." Democratic Representative Debbie Dingell of Michigan called the order "idiotic" and announced plans for congressional legislation to nullify it, stating:

"The Great Lakes are a shared treasure that generations of Americans and Canadians have worked together to protect."

Former New Jersey Governor Chris Christie criticized the timing of the announcement, calling it "Childish. Completely childish," while former White House aide Sarah Matthews observed:

"I bet this goes so f***ing hard if you’re stupid".

Conversely, Interior Secretary Doug Burgum praised the initiative, posting online, "We're on it, Mr. President!" and adding:

"The places and waters that border our nation and support our economy should reflect the greatness of the United States" adding that the Geological Survey "maps our country for the world to see, and we are PROUD to implement your Executive Order to rename LAKE AMERICA".

The executive order mirrors a similar move from early 2025, when Trump signed an order to rename the Gulf of Mexico as the "Gulf of America". That decision was rejected by Mexico, though it prompted tech companies like Google to adjust map displays based on user location. The previous directive also sparked an ongoing lawsuit from The Associated Press after the White House restricted press access over the news agency's refusal to adopt the "Gulf of America" phrasing in its reporting. 

In the same 2025 order, Trump also reversed a former Obama administration decision by restoring the federal name of Mount McKinley in Alaska, replacing its Indigenous title, Denali.
