In brief
U.S. President Donald Trump signed an executive order on Thursday to rename Lake Ontario as Lake America, a move linked to a 50 % tariff on Canadian goods triggered by a collapsed trade talks. The order follows Trump’s past renaming of the Gulf of Mexico to Gulf of America and has been met with backlash from Canadian officials who emphasize the lake’s long‑standing name and shared heritage. Canada plans dollar‑for‑dollar counter‑tariffs and has dismissed the renaming claim. This latest order reflects broader U.S. attempts to assert federal naming rights over international waters in the heat of escalating bilateral disputes.
Renaming Controversy Sparks Can‑American Tensions
Trump’s executive order came after Canada hit with a 50 % tariff on $20 bn of Canadian imports. The U.S. imposed the high duties in response to stalled trade talks, while Canada vowed a dollar‑for‑dollar retaliation.
The directive declares the lake officially “Lake America,” effective immediately. Trump said the change reflects “America’s right to define its own geography” and that all paperwork has been filed.
Canadian Prime Minister Mark Carney tweeted that the name originates from the 17th‑century French‑North‑America era, underscoring the lake’s indepedent heritage.
The renaming echoes Trump’s earlier drive to call the Gulf of Mexico the Gulf of America—an action rejected by Mexico and prompting Google Maps to display “Gulf of America” for U.S. viewers while “Gulf of Mexico” remains in Mexico. The same glitch left users elsewhere with “Gulf of Mexico (Gulf of America).”
Canada’s Industry Minister Melanie Joly performed a brief on the policy: “We’ll always call it Lake Ontario.” No international body governs the naming of shared bodies of water.
The order will be applied to the U.S. Geographic Names Information Service, but Canada is free to keep its designation. The renaming came as the two countries floated a potential return to negotiating positions.
