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,

The president-elect said that he would impose the across-the-board tariffs on Day 1 and that they would stay in place until Canada, Mexico and China halted the flow of drugs and migrants.

Another check on the administration could be the fear of tariff-induced inflation. Americans’ experience of the highest price rises in 40 years helped doom Kamala Harris’s election bid. Mr Trump may not want to be seen as the architect behind surging prices of everything from Americans’ breakfast avocados to their newest set of wheels.
