For users outside the US, the two names now both appear.
American users opening Google Maps will now see Lake America stretching along the northern border.
The search giant updated its system after President Donald Trump signed an executive order renaming Lake Ontario.
According to TIME, who first reported the change, Canadian users still see Lake Ontario on their screens. Meanwhile, people searching from the rest of the world get both names displayed side by side.
Google said the change follows standard policy for bodies of water with disputed national labels. The update was triggered by the official database of geographic names in the United States.
Tech world splits
Not every tech firm joined the shift. MapQuest mocked the decision online and gave users a tool to rename the lake whatever they liked.
“We’re not changing the name of Lake Ontario. Name it whatever you want at your leisure,” MapQuest posted on social media.
Apple Maps took a different path. By Sunday, the company had not updated the label for American users.
Trump Avenue – TACO Avenue
The renaming follows an escalating trade conflict between the neighboring nations with trade talks collapsing earlier in August.
This led Trump to impose new tariffs on certain Canadian goods with Canada retaliating with similar tariffs shortly after.
Following the breakdown in trade negotiations between the US and Canada, Donald Trump officially renamed Lake Ontario to Lake America.
Among the suggested new names are TACO Avenue – The shorthand references an acronym born online during recent tariff arguments, standing for “Trump Always Chickens Out.”
