Overview
- On Thursday, Aug. 27, 2026, President Donald Trump signed an executive order directing the Interior Department and the U.S. Board on Geographic Names to update federal records and maps to show the name “Lake America” within 30 days.
- U.S. Geological Survey director Ned Mamula said the agency has already applied the new name to electronic USGS documents and will update printed materials in the coming days.
- The order affects only how the U.S. government refers to the lake and does not bind Canada, international mapping bodies, or provincial authorities under existing cross‑border water treaties.
- Canadian leaders including Prime Minister Mark Carney and Ontario Premier Doug Ford said they will continue to call the body of water Lake Ontario, and New York Governor Kathy Hochul likewise rejected the change.
- The renaming follows the collapse of trade talks and recent reciprocal 50% tariffs on billions of dollars of goods, raising risks for border industries, state constituencies, mapping providers, and indigenous communities tied to the lake’s historic name.
