Chicago – August 27, 2026
President Donald Trump has signed an executive order renaming Lake Ontario as “Lake America” within the United States, intensifying a bitter trade dispute with Canada. The order, signed on Thursday, 27 August 2026, directs the US Interior Department to update the lake’s designation in the federal Geographic Names Information System within 30 days.abc.
The White House justified the move by claiming that the deepest parts and majority of the lake’s volume lie in US territory, calling it a “flourishing economic resource” critical to the nation. Trump announced the change as “effective immediately” during an Oval Office briefing, flanked by maps relabelled “Lake America.”
Canada, however, has rejected the unilateral renaming. Prime Minister Mark Carney stated the body of water would remain “Lake Ontario then, now and always,” noting the name’s Indigenous origins and its recognition in international treaties. Legal experts say the US president cannot compel Canada or international bodies to adopt the new name, though federal agencies must use it domestically.news.
The decision follows collapsed trade talks and reciprocal tariffs, with Washington imposing 50% duties on C$20 billion of Canadian goods. Analysts describe the renaming as a symbolic escalation in an increasingly confrontational economic standoff between the longtime allies.
