The answer to this question is a bit complex. You're getting into the nuts and bolts of how the CHT is actually calculated. Part of the CHT calculation, as you're rightly pointing out, deals with the tax point transfer. But the tax point transfer, the equalization system, also takes into account the ability of provinces to raise income taxes. So there's an offsetting calculation that happens within CHT. There is an adjustment made for the amount of money that equalization is already providing, which brings the level of the tax point transfer up to a certain level.
But they didn't recognize a negative amount, which is what was going to happen to Ontario when it became a receiving province in 2009-10. We made an adjustment that recognized this inequity to the Province of Ontario in the form of an additional payment that was made in 2009-10 and again in 2010-11. That system in 2011-12 is longer available for Ontario, and Ontario will be treated just like any other equalization-receiving province.
