For curiosity, I checked the form and found the line-6112 is for
"Property tax paid in Ontario in 2009", which appears to me not related to mortgage and its interests.
If my understanding is wrong, can you please explain a little bit in detail? Thanks!
mortgage interest only claimable when you do business in your property or using your property as part of your office. Fill the mortgage interest in business income section of the T1 return
