Mark Carney says "Lake Ontario - today and forever" after Trump's order renaming it Lake America

After trade talks broke down and Washington imposed new 50% tariffs on $20bn of Canadian goods, President Donald Trump signed an executive order redesignating Lake Ontario as Lake America in U.S. records. Prime Minister Mark Carney responded that the lake’s existing name, which predates both countries, should remain unchanged. The order requires Interior Department action within 30 days; other nations do not have to follow. Canadian officials dismissed the move, while U.S. politicians were split, with a Michigan Democrat promising legislation against it. It follows Trump’s earlier renaming of the Gulf of Mexico, also disputed by Mexico. No international body controls names of shared waters, and the move came amid strained U.S.-Canada relations.
