# What happened
U.S. President Donald Trump signed an order on August 27 that renames Lake Ontario to "Lake America." The U.S. Geographic Names Information System (GNIS) updated its database with the new name, and major map platforms have been adjusting how they label the lake.
# How map providers reacted
Google Maps changed the label earlier, using a location-based display: Canadian users see Lake Ontario, U.S. users see Lake America, and users outside those countries see both names. Apple Maps has followed that approach for U.S. users, updating the label to Lake America in the United States while Canadian users still see Lake Ontario. International users commonly see both names together (Lake Ontario and Lake America).
# What prompted the change on Apple Maps
Reporting indicates President Trump asked Apple directly to make the change. The U.S. Secretary of the Interior told Fox Business that Trump "reached out to Apple directly" about renaming the lake, and that the change might be seen in Apple's Maps app soon. Apple previously adjusted the Gulf of Mexico label after a similar presidential rename, which set precedent for this update.
# Differences across services
Not every mapping service complied. MapQuest reportedly refused to change the Lake Ontario name, and that stance gained attention. Other services have been making their own decisions based on GNIS updates and corporate policies, which is why users in different countries may see different labels for the same body of water.
# Background on the original name
# What this means for users
If you use Apple Maps or Google Maps, the lake name you see will depend on the app's regional handling and your device's location settings. Tapping the lake label in Apple Maps may show the alternative name depending on platform updates. For cross-border or international use, expect maps to either list both names or to present the name associated with the country where your account or device is registered.
# Quick takeaways
- Expect different labels based on where your device or account is registered. U.S. users will generally see 'Lake America.' Canadian users will see 'Lake Ontario.'
- The original name, Ontario, has Indigenous origins and a long history.
# Where coverage stood at publication
MobileSyrup reported Apple's change on September 1, 2026, noting the split display across countries and linking the sequence of events back to the GNIS update and prior actions by Google. Other outlets, including MacRumors and regional broadcasters, reported similar updates to Apple Maps and described the country-dependent display approach.
