Momentum is growing among President Trump’s advisers to place 25% tariffs on Mexico and Canada as soon as Saturday, bucking conventional wisdom in Washington and on Wall Street that he would back off the threatened levies as he has in the past in exchange for concessions.

Outgoing Canadian Prime Minister Justin Trudeau says prices for Americans will go up if President Donald Trump follows through with his vow to apply sweeping tariffs on Canadian products.

While much about the threatened tariffs is still unclear, experts predict they would be bad news for all three economies, with few winners.
