Prime Minister Justin Trudeau and the premiers will meet Wednesday to discuss strategy as president-elect Donald Trump threatens to upend the bilateral relationship with punitive tariffs on everything Canada sends to the U.

A government official says Canada is already examining possible retaliatory tariffs on certain items from the United States should President-elect Donald Trump follow through on his threat to impose sweeping tariffs on Canadian products.

Many of the prime minister’s political opponents were as critical of him as about the president-elect’s plan, which would adversely affect Canada’s economy.
