Notably, none of the goods you just mentioned about (energy imports, uranium, potash, etc.) have had tariffs applied by the Trump regime because they know all this. And it would be political suicide to apply an export tax on them.

No, instead the Trump tariffs have specifically targeted the regions of Canada that a) elect left of centre governments and/or b) have manufacturing economies.

So Ontario's auto sector, BC's forestry, and Quebec's aluminum and aerospace sectors.

Meanwhile Alberta and Saskatchewan -- which have compliant quite honestly pro-Trump governments -- have only 2% of their exports currently impacted by tariffs.

It has the look of an attempt at regime change, masquerading as economic policy.
