It will take an investment of $7.5 billion over the next 30 years to bring Toronto Community Housing properties up to a proper state of repair, according to a report from The Canadian Centre for Economic Analysis.

Mayor John Tory wants to ask senior governments to help cover the cost but Coun. Gord Perks said Wednesday in an interview on CBC Radio's Metro Morning show that it's not realistic to expect senior governments to pick up the costs.

"It's been very clear for about 15 years that the federal and provincial governments have no interest in paying for the long-term maintenance and repair of Toronto Community Housing properties," he told host Matt Galloway.

Perks is suggesting a tax increase to cover the repair bills.

"Each time we fail to keep one of these big buildings in shape, people lose their homes."
