It is in this sense that I consider that we can't exclude the carbon price policy from this consideration. You have to send a price message. If we accept there is a carbon-related environmental cost, it has to be reflected in the price in a certain way. I don't think we can ignore the role of the carbon pricing policy.
However, as we have seen in our analysis—and I could expand on this—the carbon tax should be so high that we would create a huge competitiveness challenge for the Canadian economy. We can't do this overnight. It's part of the toolkit, but it's not the ultimate solution.
