If I could make a comment on the question, let's remember that of all the federations in the world, Canada is the most decentralized. When you look at the revenue-raising capacity, the fiscal capacity, and the programming capacity of subnational levels of government, i.e. the provinces and territories, it's significant in terms of their own capacities to undertake programs.
Secondly, there are significant provisions for various opting-out arrangements between the federal and provincial governments, which I think are very important to the provinces. It allows them to receive cash from the federal government to undertake their programs in lieu of opting in to a national program. I think that's a very significant factor.
Thirdly, let's never forget--and I think this was mentioned by Dr. Young--the ability within the federation to do things differently in provinces, whether it is a carbon tax in B.C. or a carbon tax in Quebec. These are agendas that can be moved forward at the provincial level even when we don't necessarily want to, or are not quite sure how to, move at the federal level.
I think there are some great advantages to the federation, particularly with regard to undertaking social policy experimentation and social policy change.
