Lake Ontario has been renamed by U.S. President Donald Trump, who issued an executive order to change the body of water to “Lake America” amid ongoing trade tensions with Canada. The proposal targets one of the five Great Lakes, which is jointly managed by the United States and Canada under the historic Boundary Waters Treaty.
Trump Proposes Lake America Renaming Amid Trade Disputes
President Donald Trump announced the name change on his social media platform, Truth Social. According to the president’s public statement, the administration is seriously considering renaming Lake Ontario because relations with Canada do not necessitate maintaining the current designation.
Canadian Officials Reject U.S. Renaming Plans
Canadian leadership quickly pushed back against the proposal. Canadian Prime Minister Mark Carney stated that the nation will call the shared body of water Lake Ontario “for ever.” Ontario Premier Doug Ford adopted an even firmer stance on August 29 by erecting a large sign on the Canadian shoreline bearing the name “Lake Ontario” alongside the phrase “Now and forever.” Because the boundary waters are governed by a binational treaty established in the early 20th century to resolve resource disputes, unilateral U.S. action cannot legally alter Canada’s official nomenclature.
Previous Geographic Renaming Efforts by the Administration
This proposal follows a similar geographic redesignation initiated earlier in the presidential term. On his first day back in the White House in January 2024, President Trump signed an order renaming the Gulf of Mexico to the “Gulf American.” Major tech platforms, including Google, adjusted their digital mapping services to reflect the government’s official terminology within U.S. jurisdictions following that directive, establishing a precedent for domestic map alterations while international neighbors retain their own designated names.
