No, not at all. I should clarify. I certainly didn't mean to portray a carbon tax as a one-size-fits-all or say that all we need is a carbon tax and we're away to the races. A carbon tax is a powerful tool, but it needs to be part of a suite of programs and policies that Canada puts in place in the short term to begin driving our emissions down.
A carbon tax is compatible with a permit trading system. There are economists who have looked at the possibility of using those two mechanisms jointly, and that's something that could be explored in Canada. But it's really important to understand that there are both pros and cons with all of the policies and tools we're talking about. What we really need to do is put these things in place and start using them, and then we can make adjustments as time goes by.
