Mr. Mercille, I can confirm that it actually will be happening. There was an exchange between Mr. Fergus and Mr. Coulombe in French about la tarification du carbone.
The GST—HST in some provinces—is going to be applied on the carbon tax. That's already double taxation. So I can tell you, it's already going to happen. It's $100-plus million in revenue that it is going to generate the federal government. This is already going to happen.
Could that exemption be used here?
The reason I bring it up is that you're going to exempt people from being taxed unfairly. Well, there's an entire electoral system designed around people having their say at the provincial level to refuse to have the carbon tax. We have an election coming up in Ontario in June; there's an election coming up in Alberta in 2019. There's a very strong chance that those provincial governments will change their minds.
