I don't understand what you mean, TDWfromTPM.  Federal income tax rates are determined by the Government of Canada, and provincial tax rates are determined by the Government of Alberta.

Perhaps the only place where one jurisdiction might tax the taxes paid by another may be when GST is applied to the cost of an item, and that cost includes PST. I think that's what "harmonized sales tax" means.

So your post only makes sense to me if Alberta chooses to implement a sales tax. Is that what you are saying
