Google Maps has begun showing different names for the same body of water depending on where users log in from. For those in the United States, Lake Ontario now appears as "Lake America," following an executive order by President Donald Trump. Canadian users, however, still see the centuries-old name, and international users see both labels.
The change, confirmed by Google on its official blog, aligns with the US Geographic Names Information System (GNIS), the federal database that governs official place names. "Since we update Google Maps to reflect name changes in official government sources, which is GNIS for the US, people using Maps in the US will see 'Lake America,' those in Canada will continue to see 'Lake Ontario,' and those outside of the US and Canada will see both names," the company stated.
This is not the first time the Trump administration has unilaterally renamed a geographic feature. In January 2025, the Gulf of Mexico was officially changed to the Gulf of America for US users, a move Mexico rejected. Now, the same logic has been applied to the smallest of the five Great Lakes, which straddles the border between Ontario and New York State.
A symbolic move in a trade war
The renaming comes amid an escalating trade conflict between Washington and Ottawa. President Trump has imposed tariffs on Canadian goods, including a 25% levy on non-US content in Canadian-built vehicles, set to double to 50% from 1 January 2027. Canada has retaliated with counter-tariffs ranging from 15% to 50% on US products.
Ontario Premier Doug Ford, who has been a vocal critic of the trade war, dismissed the name change as "absolutely backwards." In an interview on ABC's This Week, he said: "It was like something out of Saturday Night Live when he signed documents saying change it to Lake America. No one is going to call it Lake of America. It's been Lake Ontario for hundreds of years, it's going to continue being Lake Ontario."
Ford also warned that the trade war would hurt American consumers and workers. "A tariff on Canada is nothing more than a tax on American people," he said. "It's probably the worst move you could ever do."
The automotive sector is particularly vulnerable. Canada exported C$78.6 billion (€50 billion) in automotive products in 2025, with nearly 95% going to the US market, according to DesRosiers Automotive Consultants. Parts often cross the border multiple times before a vehicle is fully assembled, meaning tariffs can compound. President Trump, however, remains defiant: "I don't want Canadian cars, I don't want Canadian parts, I don't want Canadian anything," he posted on Truth Social.
Apple, which pre-installs its Maps app on iPhones in the US, has so far retained the name Lake Ontario. The discrepancy highlights the growing divergence in how the two countries perceive their shared geography and history.
For Europeans, this spat may seem distant, but it underscores the fragility of transatlantic alliances and the ripple effects of US trade policy. As Canada seeks deeper ties with the EU, the question of whether such symbolic gestures will further strain relations remains open. The potential for a closer Canada-EU partnership is a topic of ongoing discussion, though full membership remains off the table.
Meanwhile, the trade war continues to escalate, with Canada imposing sweeping counter-tariffs on US goods. The impact on European markets, particularly in the automotive and manufacturing sectors, is being closely monitored.
As the dispute deepens, the name on a map has become a symbol of a broader rift. For now, Lake Ontario remains Lake Ontario for Canadians, but for Americans, it is Lake America—a change that reflects not just a cartographic update, but a political statement.
