President Donald Trump posted on social media platform X on September 4 that the renaming of Lake Ontario to "Lake America" has been warmly received, especially by American patriots. Trump claimed the name change has been affirmed by Google Maps, Apple Maps, and Microsoft's Bing Maps, and asserted that business on the U.S. side of the lake has been "absolutely BOOMING" since the change.

In his post, Trump wrote: "People, especially Patriots from the United States of America, love the name change of Lake Ontario to Lake America! The support has been overwhelming, including affirmation from Google Maps, Apple Maps, and Microsoft’s Bing Maps." He added that the change has led to a surge in commercial activity.

No official announcement regarding the renaming of Lake Ontario has been made by relevant authorities. Trump's statement has not been independently verified by the technology companies mentioned or by government agencies. Lake Ontario, one of the Great Lakes of North America, lies on the U.S.-Canada border, and any name change would involve international naming conventions.
