Okay. I'll be very quick.
I talk about this in my classes. I don't think anyone should deny the Pigou tax. Professor Pigou created the idea of putting a tax on something. Make it more expensive, and we consume less of it. That's a Pigou tax—a carbon tax, a cigarette tax or an alcohol tax. They work.
The problem is, in this instance, we're in a unique market. We think we're huge in Canada, and we are, geographically, but we're very small. We're smaller than the state of California. There are fewer people in Canada than in California, and they do not have a carbon tax. They are our largest competitor. Pierre Trudeau said they are our best friend, whether we like that or not.
