Trump Moves To Rename Lake Ontario As ‘Lake America’ Amid Growing Rift With Canada

US President Donald Trump has signed an executive order seeking to rename Lake Ontario as “Lake America,” escalating his ongoing dispute with Canada and Prime Minister Mark Carney. The Great Lake, which lies between the United States and Canada, shares its name with the Canadian province of Ontario. Trump made the announcement amid an intensifying trade dispute between the two countries, comparing the move with his earlier attempt to rename the Gulf of Mexico as the “Gulf of America.”

US President Donald Trump has signed an executive order seeking to rename Lake Ontario as “Lake America,” adding a new dimension to his increasingly tense relationship with Canada and Prime Minister Mark Carney.
The announcement came on Thursday as a trade dispute between Washington and Ottawa continues to deepen.

TRUMP TARGETS LAKE ONTARIO

Lake Ontario is one of North America's five Great Lakes and sits along the border between the United States and Canada. It shares its name with the Canadian province of Ontario.
Speaking in the Oval Office, Trump criticised Canadian officials, saying the relationship between Washington and Ottawa had deteriorated.
The proposed name change is unlikely to affect the lake's geographical status or Canada's continued use of its existing name, but it could become another source of political friction between the two countries.

MOVE COMES DURING TRADE DISPUTE

The announcement follows an escalation in the US-Canada trade conflict, with both countries imposing or threatening tariffs on each other's goods.
The dispute has strained traditionally close economic ties between the neighbouring countries. Trump has repeatedly argued that Canada benefits disproportionately from its relationship with the United States, while Canadian officials have rejected Washington's demands.
The latest renaming proposal therefore comes at a particularly sensitive moment in bilateral relations.

FOLLOWING THE ‘GULF OF AMERICA’ MOVE

Trump's latest proposal mirrors an executive order he signed in January 2025 seeking to change the name of the Gulf of Mexico to the “Gulf of America.”
That decision generated controversy, particularly outside the United States, where the traditional name remains widely used.
Trump defended the Lake Ontario proposal by pointing to the earlier Gulf renaming effort, saying the new name had become increasingly common in the United States.

TRUMP JOKES ABOUT RENAMING OCEANS

Trump also took the idea further during his remarks, joking that if the United States had an “America” gulf and an “America” lake, the country might eventually consider renaming an ocean.
He mentioned the Atlantic and Pacific oceans as possible targets, although there was no indication that an official proposal to rename either body of water was being seriously pursued.

CANADA YET TO ACCEPT THE NEW NAME

Because Lake Ontario is shared by the United States and Canada, Trump's executive order cannot by itself determine what Canada calls the lake.
The proposal is therefore likely to remain primarily a US naming policy unless Canadian authorities or international organisations adopt the new terminology.
The development highlights the increasingly unconventional nature of the US-Canada relationship under Trump's administration.
What was once one of Washington's closest partnerships has become increasingly marked by disputes over trade, sovereignty and political rhetoric.
