Mr. Speaker. The policy within the Housing Corporation is that we have a limit on housing, so, when houses get too close to 50 years old, then we try not to do too much renovation. We do an assessment to see if it would be cheaper for us actually to build a new unit. When they get to the homes in the '70s, after I did the math on my fingers, actually will be hitting that time zone so that we look at: is it more cost effective to actually renovate, or is it more cost effective to actually demolish them and put up new units?
