First of all, I want to emphasize that we were very much in favour of shifting the operating rules for the Canada Pension Plan. We did the right thing a decade ago when we put it on an actuarially sound basis. In view of the aging population, we think we also have to shift the operating rules.
We actually haven't analyzed how that plays throughout the tax system. Clearly, there are going to be fiscal impacts. But I can't actually speak to this in detail, because we haven't analyzed it.
