Lake Ontario, which US President Donald Trump renamed Lake America, got its name over 400 years ago, long before the US declaration of independence, and will keep it, Canadian Prime Minister Mark Carney said.

"The name Lake Ontario comes from the Wendat word Ontari’io, which, appropriately, means ‘the lake is beautiful, the lake is big,’" Carney wrote on the X social network. "The name is more than 400 years old, predating both the Confederation of Canada and the Declaration of Independence of the United States of America."
