From a Canadian perspective I think (hope) these tariffs and other Trump international antics may be a blessing in disguise. Short term pain for long term gain. Canada has far too long been reliant on the US as the major trading partner. Time for Canada to go to work and create more diversity in sourcing alternatives rather than picking the low hanging fruit as in the US just because it is next door. IMO the US can not be relied upon anymore to stick to international agreements ala global warming withdrawal, Iran agreement, NAFTA .....
I hope Canada can make the recent trade agreements with the TransPacific and European work. A good step in turning away from the US as the major partner in trade.
