The Environment Minister said in interview that the provinces must each have a price on carbon or a cap and trade process but that each province could do what it wished with the money collected.  Note that Ottawa has left it up to individual provinces to administer collection and bear the cost, just as BC does now.  Might this not lead to the provinces collecting their own income tax, administering their own costs and sending Ottawa what's left.  They could get the formula from Quebec, which I believe does that now?
