Ontario is proposing changes to the Greater Golden Horseshoe's growth plan that the government says would make it easier and faster to build housing.
The government says the changes would come while maintaining protections for the Greenbelt, an area designated to keep environmentally sensitive land from urban development.
Critics have suggested the Progressive Conservative government wants to open the door to Greenbelt development, but it has denied that charge.
The proposed changes to the growth plan include some eased density targets.
The previous targets, introduced by the former Liberal government as anti-sprawl measures, had been blamed by some critics for a housing supply shortage in the Toronto area.
The government says the current vacancy rate in Toronto is close to one per cent, and two to three per cent is generally considered to represent a balanced rental market.
