Justin Trudeau says Canada is ready to respond with counter-tariffs against the US if President-elect Donald Trump follows through on his threat to begin a trade war in North America.

President-elect Donald Trump’s rhetoric around Canada becoming a 51st state is a distraction from the economic impact a trade war will have on American workers and businesses, Prime Minister Justin Trudeau charged Sunday.

Canada is preparing to retaliate with an exhaustive list of tariffs on American goods if President-elect Trump follows through with his plans to add a steep 25% import tax on Canadian exports, people familiar with the matter told CNN.
