After U.S. President Donald Trump issued an executive order to rename Lake Ontario, which borders the United States and Canada, as Lake America, the Ontario provincial government in Canada hit back by erecting a giant sign.
On the 29th, local time, according to reports from AP and major outlets including the Toronto Star, Ontario Premier Doug Ford unveiled a large sign on the Grimsby shoreline in Ontario that reads, "Lake Ontario, now and forever." The sign, as tall as a two-story building, was produced side by side in English and French. Protesting Trump's unilateral move to change the lake's name, Ford said, "We will always protect our sovereignty and never back down to a bully." He added, "Long after President Trump is gone, this place will still be called Lake Ontario."
The clash was triggered as U.S.-Canada trade talks recently broke down and the issue of tariffs flared. As the two countries blamed each other for the collapse, Trump on the 27th signed an executive order directing U.S. federal agencies to refer to Lake Ontario as Lake America. Trump had earlier escalated a war of words, calling Ford a "lackey" working under Prime Minister Mark Carney of Canada, and mocking him as "the brother with less charisma or intelligence" than his late brother, former Toronto Mayor Rob Ford. Ford, for his part, strongly criticized Trump's tariff policy and repeatedly called him a "bully."
Prime Minister Carney of Canada dismissed the renaming, saying the name Lake Ontario long predates the U.S. Declaration of Independence and the formation of the Canadian federation. Manitoba Premier Wab Kinew jabbed that Trump is "like an aging rock band trying to reprise a past hit," referencing Trump's move in 2025 to rename the Gulf of Mexico as the Gulf of America. Canadian historian Robert Boswell sharply criticized him, saying, "Is the greatest nation on Earth taking this moron seriously?"
Indigenous communities also pushed back hard, condemning it as an attempt to erase history. The name Ontario comes from the language of the Huron people who lived in the region and means a lake of shining water. Pierre Picard, grand chief of the Huron-Wendat Nation, said, "We cannot tolerate a president who seeks to erase our history, culture and identity."
Meanwhile, Trump kept up the messaging by posting on his social media a doctored image of blond Canadian geese holding guns to defend Lake America. Nelson Wiseman, professor emeritus at the University of Toronto, said, "Trump wants Canada to behave like a vassal state, and when Canada refused, he got annoyed." With both countries signaling retaliatory tariffs and squaring off, experts said the North American trade alliance could fracture further, using this naming dispute as a starting point.
