Yes, and that points to one other difficulty, in my opinion, of costing a scenario in which we do nothing. Whether it's Canada that does nothing and is a free rider and lets other countries do their own emissions reductions or whether it's the entire world doing nothing, which is a catastrophic scenario, that leads to various different hypotheses and assumptions.
If we take Canada as a free rider, in that case there would be a cost, but it would probably be much more than economic. It would be diplomatic. It would be commercial. There are various considerations that become very tricky and delicate in estimating a scenario in which we do nothing.
