While these policies obviously harm Americans as well, their impact on Canada shouldn’t be dismissed. The reality is that the percentage of the US economy that’s dependent on trade with Canada is far smaller than the reverse. The harm to Canadian exports would be quite significant. Of course, the only rational thing for Canada to do here is to suck up short term pain and continue diversifying. The fact that we allowed our economy to become so dependent on trade with the US is the reason we’re in this mess in the first place.
