Downtown Toronto will turn into a child-free zone if apartment and condominium builders don’t start including family-friendly units in their developments, says a downtown councillor.

But developers turned up at City Hall yesterday to attack a proposal that would require 10 per cent of all units in large developments to have three or more bedrooms.

Councillor Adam Vaughan (Ward 20, Trinity-Spadina) led the charge for more family housing, saying that downtown schools are emptying out as a wave of new development suited only to singles and couples is built.

Vaughan said it’s healthy to have more children downtown, to make use of the schools, community centres and libraries that have already been built.
