What happened
On August 30, President Donald Trump shared a map on social media showing Lake Ontario, which sits on the US-Canada border, labeled as “American Lake.”
Google confirmed in a statement that it has updated the lake’s name to “American Lake” for US users, saying the change reflects an executive order Trump signed to rename the lake.
The executive order affects the US Geographic Names Information System, which sets standards for official US maps, but does not affect Canadian naming practices or how the lake is referred to elsewhere in the world.
Why it matters
This is the latest example of a tech company adjusting digital maps to align with US government naming decisions, following a similar change last year when Google Maps relabeled the Gulf of Mexico as the “Gulf of America” after a related executive order.
Because mapping platforms are used globally, such unilateral label changes can create discrepancies between US and international views of shared geographic features, raising questions about how digital maps handle political naming conventions.
Key facts
Google Maps changed Lake Ontario’s label to “American Lake” for US users.
The change was made to reflect an executive order signed by President Trump.
The executive order only affects the US Geographic Names Information System, not Canadian or international naming conventions.
Google made a similar change last year for the Gulf of Mexico, labeling it “Gulf of America.”
What to watch next
Whether Canada or other countries will take steps to ensure their own mapping services keep the name “Lake Ontario” for all users.
Whether Google’s policy of following US executive orders for name changes on shared waters will be applied to other border features in the future.
