According to Statistics Canada, 522 140 units were rented in the agglomeration of Montreal in 2016. In the same year, 4% of units were unoccupied. According to the Union des Banques Suisses, the average rent price for a 3 1/2 in Montreal in 2015 was CAD 879. We will assume that between 2015 and 2016, this price increases by 2%, therefore increases to approximately CAD 900.

To facilitate access to housing, Ms. Gagnon, economist for services of the City of Montreal, proposed to cap the price of rents at CAD 850 (ceiling price) as of January 1, 2017.
