Residential developers whose projects are subject to the By-law for a Diverse Metropolis must reach an agreement with the city. Thanks to these agreements, residents have access to a greater supply of social, affordable and family housing. The most recent results are as follows.

This page presents the main impacts of the by-law as of June 30, 2025. This information is updated every four months.

Agreements with developers

Since the by-law came into force on April 1, 2021, the city has signed 249 agreements calling for a total of $59 013 224 in financial contributions. The by-law also led to commitments equivalent to the construction of about 1072 social housing units,159 affordable housing units and 1299 family housing units.

Every agreement must include a social housing commitment. Depending on the area and the scope of the project, some agreements also include affordable and family housing commitments.

The commitments take a variety of forms: building housing units, transferring land or a building, or providing a financial contribution. 

Financial contributions are issued to the city progressively according to the project’s advancement. It may take several years before the collected sums are fully reinvested in social and affordable housing projects.

Creation of affordable housing zones

The By-law for a Diverse Metropolis is closely connected with the evolution of the Master Plan. When the Master Plan is amended to increase residential density or to allow residential land uses in a given area, the by-law is amended to create one or several affordable housing zones. Two types of zones are possible (type 1 and type 2 zones), depending on the scale of the change to the Master Plan. Projects located in a type 1 zone must include affordable housing for the equivalent of 10% of the private residential floor area, while this requirement is 20% in a type 2 zone.

Total land area designated as affordable housing zones:

  • Type 1 zones: 117,26 ha
  • Type 2 zones: 373,87 ha

Overview of the first two years of implementation 

On November 10, 2023, the results of the last two years of the By-law’s implementation were presented at a public meeting before the Commission sur le développement économique et urbain et l’habitation. The consultation documents (in French) and video recording of the meeting can be viewed on this page.   

Open data 

The city’s open data platform provides access to two sets of data regarding the by-law for a mixed metropolis. You may look up and download files pertaining to the maps used for the enforcement of the by-law, as well as to the highlights of the agreements made in accordance with the by-law.

In line with the inclusion strategy 

The By-law for a Diverse Metropolis is a continuation of the strategy for the inclusion of affordable housing in new residential projects, which it replaces. It allows to correct its limitations, particularly with regard to the projects subject to it and its incentive nature. For an overview of the benefits of the strategy, in force from 2005 to 2021, see the final report.
