No matter the reason, or outcome, I think Canada should tread lightly and not screw around. The steel and aluminum tariff was recinded for us. Again, no matter why the change of heart, but it happened. That was Trump's olive branch to get this done, as I see it. If the Trudeau government does not take their stupid social engineering off the table, quit being obtuse and get on with it, Trump is going to squash them like a bug, And I don't blame him. Doesn't matter though, China has been dumping here for years. We buy it, process it and sell it over the border.
Had a contractor here that used over a million bucks worth of Chinese stainless steel for a highway project. One week into the installation it all had to come down and be replaced with North American stuff. It was rusting, even though the paperwork said it was top quality stainless.
