Two years after Valérie Plante's administration said a new housing bylaw would lead to the construction of 600 new social housing units per year, the city hasn't seen a single one.

The Bylaw for a Diverse Metropolis forces developers to include social, family and, in some places, affordable housing units to any new projects larger than 4,843 square feet.

If they don't, they must pay a fine or hand over land, buildings or individual units for the city to turn into affordable or social housing.
