Canadian Prime Minister Justin Trudeau landed in West Palm Beach, Florida, on Friday evening for a dinner meeting with President-elect Donald Trump at his Mar-a-Lago estate, just days after Trump vowed to enact a 25% tariff on all products coming into the U.

Prime Minister Justin Trudeau said that if President-elect Donald Trump follows through on this threat to impose tariffs on Canadian products, he would be raising prices and hurting American businesses.

The president-elect’s opening salvo in trade and border talks with the United States’ neighbors is casting a harsh light on the North American alliance.
