Trump renames Lake Ontario ‘Lake America,’ Canada’s PM Carney says absolutely not

Canadian Prime Minister Mark Carney has firmly rejected US President Donald Trump’s renaming of Lake Ontario as “Lake America,” citing the name’s Indigenous origins and asserting that Canada would never accept the rechristening of the shared Great Lakes waterway.

“Canadians also know that naming reality means calling it Lake Ontario — then, now and always,” Carney wrote in a post on X on Thursday, according to Vanguard.

The pushback adds fresh friction to the already strained US-Canada relationship under Trump, which has seen disputes over trade policy, tariffs and territorial rhetoric. Carney noted that “America is changing” across trading relationships, foreign policies, national monuments and now “their hydronyms.”
