Mr. Speaker, I have been thinking about history, going back a bit and realizing that Brian Mulroney's government actually resorted to putting a price on pollution to address critical environmental problems at the time. We need only think of acid rain and CFCs.
I was wondering why it worked under Brian Mulroney and why, suddenly, under these new Conservatives, this pricing mechanism that allowed us to eliminate pollution would not work anymore. I would like my colleague to explain that.
