It appears that the most harmed by retaliatory tariffs from Canada will be the East Coast and upper Midwest of U.S.

 So, until Trump (or something else changes) (not sure what) people are going to be paying much more for electricity, gasoline, Timber, Milk, Butter, Cheese etc. etc. etc.

This problem also will ripple across the whole U.S. and Canadian and Mexico economies in various ways.

There are never ANY winners in Tariff wars only losers if they make less than around 70,000 dollars a year especially. Everything is going to cost a whole lot more especially if Gas and Diesel and electricity is about 25% more because of Canadian tariffs. Everyone's pocketbook will be affected in the U.S. and Canada and Mexico in a really bad way.
