Trump Orders Renaming of Lake Ontario to Lake America Amid Trade Row

President Donald Trump signed an executive order on Thursday that officially renames Lake Ontario as Lake America, a move that comes amid a sharp deterioration in U.S.–Canada trade relations. The order directs the U.S. Department of the Interior to update the Geographic Names Information Service to reflect the new name, effective immediately.

The renaming follows a week of escalating trade tensions. Late last week the U.S. imposed a 50 % tariff on $20 billion (C$28 billion) of Canadian goods, prompting Canada to announce “dollar‑for‑dollar” counter‑tariffs scheduled for next month. The trade dispute has been framed by both sides as a struggle over perceived unfair practices and cultural sovereignty, with Canadian officials accusing the United States of “ripping us off for a long time on trade.”

In a statement posted on the platform X, Canadian officials reiterated that the name Lake Ontario has been in use for more than 400 years, predating the Canadian Confederation and the U.S. Declaration of Independence. They stressed that the lake would continue to be called Lake Ontario “today and forever,” underscoring that the United States cannot unilaterally rename a shared body of water.

Trump’s order echoes a similar executive action taken when he took office in 2025, in which he renamed the Gulf of Mexico as the Gulf of America. Mexico rejected the change, arguing that a single country cannot rename a shared international body of water. The dispute spilled over into the digital realm when Google Maps began displaying “Gulf of America” to U.S. users while showing “Gulf of Mexico” to Mexican users, and “Gulf of Mexico (Gulf of America)” to users in other countries. The White House also barred Associated Press reporters from presidential events over the news agency’s refusal to use the new name, prompting the AP to sue the administration—an ongoing legal battle.

The Great Lakes, of which Lake Ontario is the smallest, have names derived largely from Indigenous languages, with Lake Superior named after an anglicised French word. The lakes straddle the U.S. and Canadian borders, and their names have been historically recognized by both nations. The renaming of Lake Ontario has therefore been met with sharp criticism from Canadian officials, including Nova Scotia Premier Tim Houston, who dismissed the change as “foolishness,” and Industry Minister Melanie Joly, who affirmed that Canada would continue to use the original name.

Trump, speaking from the Oval Office, said the order was not a direct message to Canada but a response to what he described as long‑standing trade grievances. He added that he had been considering renaming the lake for a long time, citing the Gulf of Mexico rename as a precedent, and suggested that the United States might eventually rename the Atlantic or Pacific Oceans.

Canadian trade minister Dominic LeBlanc, in a post on X, indicated that the United States had withdrawn some demands regarding French‑language labeling requirements and would not subject measures to promote French language and Canadian culture to future trade actions. He called for constructive clarifications that could lead to a mutually beneficial trade agreement respecting Canadian sovereignty.

Trade talks collapsed late Friday night after both sides accused the other of last‑minute changes to a tentative deal. The U.S. has now withdrawn some demands, while Canada has reiterated its insistence on preserving its territorial names and cultural identity. The renaming of Lake Ontario has added a symbolic dimension to the broader dispute, highlighting the tensions over national identity and international cooperation.
