That's very helpful.
Now with respect to a carbon tax, some provinces have a carbon tax and cap-and-trade system. Some don't have any carbon pricing. We also asked the minister at the last meeting if she could tell us how much of an effect a $50-per-tonne carbon price, once fully implemented across Canada, would have on greenhouse gas emissions. She was either unable or unwilling to say.
In your work with the provinces in auditing progress under the federal government's climate change plan, have you been able to identify whether any work has been done by any government within Canada on how much a carbon price will lead to emissions?
