Apple Maps has changed the name of Lake Ontario to "Lake America" for users in the United States after US President Donald Trump signed an executive order renaming the body of water for US federal use.

Trump celebrated the change in a Truth Social post on Wednesday, after Google Maps had previously adopted the new name for US users.

"Apple Maps has just announced that it has changed the name of Lake Ontario to Lake America, so now that very important change of names, between Google Maps and Apple Maps, is complete, ratified, and binding," Trump wrote.

Trump signed an executive order on August 27 renaming Lake Ontario as "Lake America" for US federal use, two days after he first floated the change amid escalating trade tensions with Canada.

Google Maps previously changed the lake's name to "Lake America" for users in the United States. Canadian users continue to see "Lake Ontario," while users outside the US and Canada see both names.

Trump bashes Canada amid trade tensions

Trump's initial proposal to rename the lake came amid a flurry of claims by the president against Canada, including that it has been “ripping off the US for decades” by charging US farmers more than 400% in tariffs, driving companies out of business, and causing the US to lose an average of $60 billion a year.

Canadian and US officials have been for over a year caught up in an ongoing tit-for-tat tariff war that has rocked the countries' long-standing ties.

Canadian Prime Minister Mark Carney said last week that "substantial progress" had been made in talks, but that there was still "important work to be done."

Canada on Tuesday, in an effort to match Washington’s latest duties dollar for dollar, hit back with retaliatory tariffs on about $20 billion worth of US annual imports.

Canadian Finance Minister François-Philippe Champagne said that the country's "dollar-for-dollar, rate-for-rate counter-tariffs as well as a multi-billion-dollar support package will protect workers, farmers, families, and businesses."

The tariffs are set to take effect on September 8 and impose duties of up to 50% for around 700 American products.

Meanwhile, Trump’s new 50% tariffs on $20 billion of Canadian imports went into effect on Saturday after failed talks between the two countries.

Lake Ontario sits on the border between Canada and the US, although around 53% of it is in Canada. It is the smallest and easternmost of the five Great Lakes of North America.

Trump has also renamed the Gulf of Mexico the "Gulf of America" for US federal use, a move that led US government agencies to adopt the new name.

The White House previously published an image on X/Twitter of a US map with the labels "Lake America" and "Gulf of America" where the bodies of water are located.


Commenting on Trump's initial social media posts, Canada-US Trade Minister Dominic LeBlanc told CNBC that the federal government had decided “months ago not to respond to sort of the daily social media posts of either the president or his Cabinet secretaries.”

“We’re focused on doing what we can in Canada to build our economy and to having a constructive relationship with the government of the United States, our most important trading partner,” CNN cited him as saying.
