The only thing this trade war achieved is having Canadians realize how much we're codependent on the USA (They're codependent on us too, but that's not relevant to the point here)....
And we realize that's probably a bad thing. So let's do what we can to not be that way.
One country representing something like 3/4s of our annual trade is not great. Maybe the numbers are smaller (or even larger) but the actual figures don't matter that much. The point is that we're too dependent on the USA for trade already, and that should change. It will help us have a better global position as the "first world" power that we are.
It's just, long past due for us to reduce or eliminate our dependence on the USA.
