Apple Maps has renamed Lake Ontario as Lake America in its U.S. app following a Donald Trump executive order amid trade hostilities with Canada.

Canadian users continue to see the lake’s original name. Apple’s decision mirrors a similar change by Google, triggering criticism from users and political observers.

Washington imposed a 50% tariff on $20bn of Canadian exports, prompting Canada to announce a "dollar for dollar" counter‑tariff. The U.S. Interior Department is tasked with updating the official Geographic Names Information System within 30 days.

Tensions escalated when Trump posted AI‑generated videos showing the replacement of a Lake Ontario sign with a Lake America plaque. In response, Canada mounted a sign declaring "Lake Ontario. Now and Always". Ontario Premier Doug Ford noted the sign is a reminder that the lake’s name will remain unchanged.

While Apple’s map change is jurisdiction‑specific, it underscores how geopolitical disputes can bleed into everyday technology. U.S. users now view Lake America, a move that symbolises the broader trade war and the contested authority over geographic nomenclature.
