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.

The leader of Ontario said he will be calling an election next week because he needs a mandate to fight Trump's threatened tariffs.

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