Apple Maps joins Google in renaming Lake Ontario to 'Lake America' for US users

Key points

• Apple Maps changed the label for Lake Ontario to 'Lake America' for US-based users on Tuesday, September 1, 2026.
• The change follows an executive order by President Trump, signed on August 27, 2026, directing the Interior Department to update the US Geographic Names Information System (GNIS).
• Google Maps implemented a similar change on August 29, 2026, citing official government sources for its naming conventions.
• Canadian Prime Minister Mark Carney and Ontario Premier Doug Ford rejected the name change, emphasizing the lake's Indigenous origins and historical significance.
• MapQuest, which refused to change the name, saw a surge in downloads, topping the US and Canadian App Store charts for free apps.
• New York Governor Kathy Hochul stated that her state will continue to refer to the body of water as Lake Ontario.

Background

This development follows a similar renaming of the Gulf of Mexico to 'Gulf of America' in January 2025, which both Apple and Google Maps adopted for US users. The current dispute is part of a broader trade war between the US and Canada, with Trump's administration using geographic renaming as a political tool. The name 'Lake Ontario' has historical roots dating back over 300 years, derived from Indigenous languages, and was referenced in the 1776 Second Continental Congress and the 1783 Treaty of Paris.

How outlets are covering it

Business Insider and WYFF4.com report that Apple and Google Maps have complied with the US government's naming change for US users, while international users continue to see 'Lake Ontario.' USA Today frames the move as part of a broader pattern of Trump branding and renaming federal entities, including the Department of Defense and the Kennedy Center. Canadian officials, including Prime Minister Mark Carney and Ontario Premier Doug Ford, have strongly opposed the change, calling it a provocation. MapQuest has defied the order, allowing users to choose their own name for the lake, which has led to a surge in its app downloads.

Why it matters

The renaming of Lake Ontario highlights the intersection of technology, politics, and international relations. It demonstrates how executive orders can influence private companies' operations and how geographic naming can become a tool in trade disputes. The backlash in Canada and the surge in MapQuest downloads indicate public resistance to the change, while the compliance by major tech companies reflects the influence of US government policy on digital platforms.

What to watch

The US Geographic Names Information System (GNIS) is expected to formally update the name of Lake Ontario to 'Lake America' within 30 days, as directed by the executive order. The legal and political battle over the name may continue, with potential challenges from Canadian officials and private companies. The impact on US-Canada trade relations and public opinion will be monitored in the coming weeks.
