Around 2 per cent of rentals are slums where if they closed them down people would be homeless. If those rentals were completely renovated in a matter of time they would turned into slums. Had a tenant who wanted a lower rental unit below where did not say no but the rent was $900 dollars Cdn. where he was paying $730 per month. The rental unit he was in was completely trashed out where cut up carpet then threw pieces over balcony as the stench along with extreme dirt. He said I was slum lord where did not want another slum completely trashed out rental unit which devalued to the rental building. Replaced flooring with porcelain tile. renovated bathroom, ripped out wall then insulated and installed new drywall. He moved out to house illegally converted rental units where I doubt he lasted more six months. You need money where on vacant rental units can go to market rent under vacancy decontrol under rent control system in the province of Ontario. Another apartment building went for above guideline increases where one January 5 rental units the moved out where the new tenants never complained about the which was below many rental units in the city. They fought the above guideline increases where they lost as this building was being hollowed where the building was dying.
