Trump Renames Lake Ontario to 'Lake America' by Order

Trump signed an executive order renaming Lake Ontario 'Lake America,' deepening a trade-war feud with Canada.

President Donald Trump on August 27, 2026 signed an executive order changing the name of Lake Ontario to "Lake America," effective immediately, according to ABC News. Speaking in the Oval Office flanked by boards depicting the new label, Trump said the change was something he had been thinking about for a long time. The move applies to official U.S. federal government use, as his January 2025 order renaming the Gulf of Mexico the "Gulf of America" did — but it cannot dictate what other countries or international bodies call the lake.

The renaming lands in the middle of a U.S.–Canada trade war that had already escalated: negotiations broke down over a weekend, a fresh round of 50% U.S. tariffs on some Canadian goods took effect on a Saturday, and Canada retaliated with levies of its own, ABC News reports. Trump used the moment to call Canada the worst country to deal with on trade, saying Canadians "feel entitled." Ontario Premier Doug Ford pushed back, saying in a statement to ABC News that it "will always be Lake Ontario to all Canadians and the rest of the world."

The president can unilaterally change a geographic name for official federal use, but the deeper stakes are historical, the New York Post argues. Citing the Treaty of Canandaigua of 1794, signed on behalf of George Washington and the Six Nations, the Post's David Polansky notes the name predates any Canadian claim and is part of an inherited heritage of place names. Rep. Debbie Dingell, a Michigan Democrat, said "Canada is not our enemy" and called the bilateral friendship one no stroke of a pen can erase.

While the political fight plays out, the Toronto Sun notes the water itself has not moved: the lake appeared on maps of North America as early as 1656, and French explorer Etienne Brule became the first recorded European to reach it in 1615. The paper highlights ten Canadian waterfront destinations along its shores — from Toronto's beaches and the Toronto Islands to Sandbanks Provincial Park, Niagara-on-the-Lake, Cobourg, and Kingston's Gord Edgar Downie Pier — insisting the smallest of the Great Lakes remains a stunning sight to behold.

Trump suggested more renamings could be ahead, telling reporters in the Oval Office, per ABC News, that the country now has "a gulf and we have a lake," so "maybe we'll have to change the name of the Atlantic and/or the Pacific. Maybe we'll change them both." With tariffs on Canadian goods at 50% in some categories and Canadian retaliation already in place, the name change signals the trade dispute is entering symbolic territory, and international bodies and other countries are free to keep using the old name.
