The Communauté Saint-Urbain (CSU) project is one of the most significant citizen and community mobilization efforts in Montreal.

 Below are the in-depth details of this social and institutional mix model for the Hôtel-Dieu site.

 Reconversion and Usage (2026 Focus)

• Social and Affordable Housing: The goal is to integrate hundreds of units (targeting 20% non-market housing) within existing pavilions or through new construction on current parking lots.

• Health and Innovation Hub: Recent proposals (2024-2025) include the creation of an ambulatory surgery center and research spaces, maintaining a health-related vocation.

• Emergency Shelter: The Le Royer pavilion continues to play a crucial role in supporting people experiencing homelessness (partnerships with the Mission Old Brewery).

• Heritage and Culture: The Musée des Hospitalières (201 des Pins Ave. W.) has seen its lease renewed until 2027, confirming the institution's permanence at the heart of the site.

 The New Avenue des Pins

The sector has been radically transformed by the des Pins Avenue redevelopment project, completed between Saint-Laurent Boulevard and du Parc Avenue.

• Sustainable Mobility: Implementation of protected and elevated one-way bike lanes.

• Greening: Planting of over 150 new trees to counter urban heat islands.

• Social Amenities: Creation of a public square at Jeanne-Mance Street and a distinctive parvis in front of the Hôtel-Dieu chapel, improving access to Jeanne-Mance Park and Mount Royal.

"Why" Analysis: Value Factors and Impacts

 Who are the Organizations?

The Communauté Saint-Urbain is a coalition born in 2013 from a consultation between three pillars of the Plateau-Mont-Royal:

• CDC Action Solidarité Grand Plateau (administrative lead).

• Milton-Parc Community Coalition for Access to Housing and Health (CCMP).

• Comité Logement du Plateau Mont-Royal.

The group now includes nearly 60 member organizations, including:

• Social/Health Sector: Mission Old Brewery, Sun Youth, Montreal Women's Centre.

• Heritage and Environment: Héritage Montréal, Les Amis de la Montagne.

• Technical Support: Atelier Habitation Montréal (GRT) and the architectural firm Rayside Labossière.

 Specific Projects and Programming

The vision is based on transforming the site into a complete living environment:

• Social Housing: Creation of approximately 300 to 310 units.

This includes the repurposing of three historic pavilions (Le Royer, Jeanne-Mance, and Masson) for ~150 units, and the construction of two new buildings on former parking lots for ~160 units.

• Target Clientele: Families, seniors, students, and people at risk of homelessness or with atypical life paths.

• Services and Community: Spaces for community groups, daycare (CPE), artist studios, community gardens, and the maintenance of a healthcare vocation.

 Timeline and Status

• 2013-2022: Mobilization phase, feasibility studies (supported by RISQ), and public consultations (OCPM).

• 2022-2026: Transitional occupation phase. The site served as a COVID-19 testing clinic and continues to house an emergency shelter managed by the Mission Old Brewery (Le Royer Pavilion).

• 2026+ Horizon: The City of Montreal has integrated the revaluation of institutional sites into its 2026 budgetary priorities.

Permanent implementation depends on the finalization of funding agreements with government levels expected in 2026.

 Budgets and Financial Aspects

• Study Funding: The Montreal Investment Fund (RISQ) financed the initial feasibility studies.

• Production Costs: As an indication, the rehabilitation of such heritage buildings requires massive investment.

  The City has already allocated funds for acquisition and transition (e.g., $5.2M for the inclusion of immigrants 2024-2026 at the municipal level).

• Economic Model: The project relies on removing the site from the speculative market to keep it in the public domain.

Social and Financial Impacts

• Social: Fighting gentrification in the Plateau, reducing homelessness through supportive housing, and preserving public access to a historic site.

• Financial: Transforming a costly "surplus asset" for the State into a hub generating social economy and local services.

• Environmental: Reduction of embodied energy through building reuse and the creation of a major urban cool island by greening former asphalt parking lots.

This sector serves as a barometer of Montreal's ability to transform large institutional holdings into complete living environments without yielding to the traditional private market.
