I would agree with you at a level, in principle. I would distinguish my answer from anything to do with Bill C-288, for reasons that are obvious in my testimony.
I agree with you. Governments deal with that. Governments look at environmental externalities. It's one of their jobs to make estimates of what the costs of those externalities are and to ensure that they're effectively priced into economic decisions, usually by regulation.
Are we going to have to push harder on that? Absolutely. Will we ever be able to measure what that externality is? No. It's a political judgment as to whether it is as big as a house or as big as a bread box. We know this one's at least as big as a house and we'd better get going.
