Trump’s threatened tariffs on Canada and Mexico may boost inflation in the U.S., but there’s still “huge uncertainty” around macroeconomic forecasts, according to Deutsche Bank Research.

If Canada seeks to retaliate over U.S. president-elect Donald Trump's tariff threat, the government should hit the U.S. where it hurt would both economically and politically, some trade experts suggest.

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.
