Finance committee  I don't think this is a matter of principle; I think it becomes a matter of practical politics. Carbon taxes are good. To get them in place, whatever it takes.... If that means reducing other taxes so that the carbon taxes are revenue neutral, that's pragmatic politics. If it means devoting the revenues to environmental causes, people tend to see that connection.

Finance committee  Yes, I think you have to. It's unfortunate to exempt the exports, but I think that unless you do that, you're just creating an incentive for industries to flee to the non-carbon tax jurisdiction over the short term. Obviously, the goal in the long term is to get more countries on board and to expand the scope of the regime.

Finance committee  Thank you, Mr. Chair. Thanks to the committee for inviting me to speak with you today and actually, more generally, for conducting a comprehensive study of tax issues in Canada. I think it's a good moment for this in Canada. It's necessary to do these things on a regular basis.
