I'd like to hear the list again, because I'm not sure they all reflect tax policy.
When you talk about transfers to provinces, I don't see that as being formal federal tax policy. It may be equalization or transfer payments, but I don't see them as representative of any type of tax policy, unless you're suggesting that other countries potentially work the same way in terms of federal transfers to provincial governments, or federal governments to a state. I'm not sure what transfers have to do with the study of tax policy.
