Trump signs executive order to rename Lake Ontario as Lake America

US President Donald Trump signed an executive order on Thursday to rename Lake Ontario as Lake America, a change he said would take effect immediately.

A White House aide said the order directs the Department of the Interior and Secretary Doug Burgum to make the change.

One of the five Great Lakes of North America, Lake Ontario borders both the Canadian province of Ontario and the US state of New York.

Prime Minister Mark Carney's office did not immediately respond to a request for comment.

Trade talks between the US and Canada collapsed last week with each side ‌blaming the ⁠other for derailing three days of intensive negotiations.

Trump claimed this week in a flurry of social media posts that Canada had been “ripping off the US for decades” by charging US farmers more than 400% in tariffs, driving companies out of business, and causing the US to lose an average of $60 billion a year.

This is not the first time Trump has renamed a body of water. On January 20 last year, shortly after beginning his second term, the Interior Department renamed the "Gulf of Mexico" the "Gulf of America."
