The provisions you're referring to are appropriated spending items. The tax credit is a fairly complex legislative change to the Income Tax Act. It was not available on the quick timing involved with this bill.
I would add, in terms of the general situatin, that even if for some reason there were not a legislative follow-up in the current Parliament for the home renovation tax credit, it would still be open to a subsequent Parliament, a subsequent government, to ratify the effect of the provision by passing the legislation.
