The concern for Canada beyond the fallout from a trade war is the fact it spent the last ten years de-industrializing. So to now re-industrialize it must do it quickly otherwise costs rise fast and unemployment explodes. If I were Carney I would start from the sectors where we have competitive advantage, regardless of whether his base will like it. He is stuck with the choice of supporting his base or doing the right thing. Oil, gas and mining should explode to help dig us out of this. I am a huge fan of environmental protections but some of the special interest groups block development too much and have far too big a voice. Economic war should mean wartime measures of 'ram it through sunshine'. Canada must act swiftly - something it has not done in decades.
