Apple has started making changes to the Lake Ontario listing in Apple Maps, with searches for "Lake America" now coming up with the Great Lake in the United States. While the map label still shows Lake Ontario, the details display the address as "Lake America, NY, United States." This change appears triggered by an update to the U.S. Geographic Names Information System (GNIS), the official database of location names. The ongoing political tiff between the United States and Canada over the body of water's identity is affecting mapping services. Currently, searches for "Lake America" outside the U.S., including in Canada, do not bring up Lake Ontario. One Apple Insider editorial member's search instead returned "America Lake" in South Dakota. This situation mirrors the recent implementation of the Gulf of Mexico to Gulf of America change in 2025. Apple relies on the same GNIS database as Google, which has already signaled the change for Google Maps. A complete label change on Apple Maps is expected within hours or the next day.

Key Entities:

• Apple Maps: Mapping service affected by GNIS update
• Lake Ontario: Great Lake being renamed to Lake America
• Geographic Names Information System (GNIS): Official U.S. database triggering changes
• Lake America: New name for Lake Ontario in U.S. searches
• South Dakota: Location of "America Lake" alternative search result
