Yes — for people using Google Maps in the United States. On August 29, 2026, Google said the U.S. Geographic Names Information System (GNIS) had formally changed the lake’s name from “Lake Ontario” to “Lake America,” and that Maps was rolling out that label for U.S. users.
Under Google’s policy for bodies of water with country-specific names, users in Canada still see “Lake Ontario,” and people outside the U.S. and Canada see both names. The change follows President Donald Trump’s Executive Order 14422 (signed August 27, 2026; published in the Federal Register on September 2, 2026), which directed Interior to rename the lake and update GNIS.
