Both the Quebec and Canadian governments are offering home-renovation tax rebates this year as an economic stimulus measure. Now the Quebec government has an on-line calculator to help you figure out how much you could get back.
Cool tool, though I have to say the disclaimer at the bottom of the page is a bit of a buzz kill:
The calculator can be used to estimate the assistance you may be entitled to, based on certain assumptions designed to reflect the most common situations. The exact amounts will be determined by the responsible departments and organizations on the basis of the specific characteristics of each measure and depending on the specific situation of each household.
It kinda reminds me of those perscription ads on TV. "If you experience double vision after applying for the Quebec home-renovation tax credit, or persistent itching, should you grow hair on your tongue or develop a third eye in the middle of your forehead, consult a professional. The Quebec home-renovation tax credit may not be suitable for all users."
