US President-elect Donald Trump is doubling down on comments suggesting that Canada will become the “51st state” and is threatening “economic force” against Canada, suggesting that the US doesn’t need anything we have.

The United States is Canada’s largest trade partner, and Canada’s premiers have already sounded the alarm about the potential impact of threatened US tariffs on Canadian goods.

The troubling comments came in a news conference in Florida in which Trump referenced the Canada-US border as “an artificially-drawn line.”

Trump suggested that tariffs should be imposed on Canadian products exported to the United States when they can be manufactured and produced in the US.

“Why should we have a $200 billion deficit? And add onto that the many, many other things that we give them in terms of subsidy,” Trump told reporters. “That’s okay to have, if you’re a state, but if you’re another country, we don’t want to have it. We’re not going to have it with the European Union either.”
