Google Maps has implemented a change for its users located within the United States, relabeling "Lake Ontario" as "Lake America." This update follows an executive order issued by President Trump late last week, which mandated the renaming of the lake. The change is visible to US-based users, while those in Canada will continue to see the traditional name, "Lake Ontario."
Google confirmed that this alteration aligns with its established policy of updating location names based on official local government data. In this instance, the U.S. Geographic Names Information System (GNIS) formally updated the name to "Lake America" on August 27, following the executive order from the Department of the Interior. For users outside of the US and Canada, Google Maps will display "Lake Ontario (Lake America)."
This is not the first time Google has made such a change; the company cited the same policy in February 2025 when it updated Maps to show "Gulf of America" for US users.
The Canadian government has stated it will not adopt the new name. Prime Minister Mark Carney noted that the name "Lake Ontario" is over 400 years old, predating both the Confederation of Canada and the Declaration of Independence of the United States. He added that the name originates from the Wendat word "Ontari’io."
Other mapping services have also reacted to the change. MapQuest, for example, publicly stated it would not be changing the name on its platform.
Lake Ontario is bordered by the Canadian province of Ontario on its north, west, and southwest sides, and by New York State in the United States on its south and east. The lake is one of the five Great Lakes of North America.
