Google Maps will now display “Lake America” for Lake Ontario in the United States, in accordance with an executive order from Donald Trump changing the GNIS, while Canadian users will continue to see “Lake Ontario.” This decision comes against a backdrop of increased trade tensions between the two countries, with customs feedback measures in force since September 8.

Lake Ontario, one of the five Great Lakes of North America, was previously known by this name in both the United States and Canada. US President Donald Trump signed an executive order on Thursday amending the Geographic Names Information System (GNIS) to rename this lake to “Lake America”. Google announced that it would update Google Maps to reflect this change only in the United States, while Canadian users will still see "Lake Ontario."
American users of Google Maps will now see “Lake America” appear on the maps, to designate this body of water located on the border of the United States and Canada, and which was previously called Lake Ontario. Google communicated the news this Sunday, which allows the American giant to comply with Donald Trump's demands. On Thursday, the US president issued an executive order to officially change the name of the smallest of the five North American Great Lakes. A decision which comes against a backdrop of growing trade tensions between the two countries.
“As we update Google Maps to reflect the name changes noted in official government sources, namely the GNIS for the United States, Maps users in the United States will see “Lake America,” those in Canada will continue to see “Lake Ontario,” and those outside the United States and Canada will see both names,” Google said in a blog post published Saturday.

The “GNIS” in question is the Geographic Names Information System, that is to say, in French, the Geographical Names Information System. This database lists more than two million physical and cultural names in the United States. The Order changed the GNIS, but this has no impact on Canadian naming conventions or how the rest of the world refers to this lake. “Canadians also know that we have to call things what they are, and this lake is called Lake Ontario – today and forever,” wrote Canadian Prime Minister Mark Carney on his X account.
Google had already renamed the Gulf of Mexico
The two countries, for the moment, are going head to head when it comes to customs taxes. Canada responded to new US customs duties that came into force on Saturday with a series of surcharges targeting certain American products, after the breakdown of trade negotiations between the two countries. These measures will be effective on September 8.
AI outlook — possibilities, not facts
Canada could respond with symbolic or administrative measures to affirm the use of “Lake Ontario” in international or educational contexts.
