Montreal Agglomeration Non-Market Housing Inventory

Government and Municipalities of Québec maintains an inventory of off-market housing projects in the Montreal agglomeration. The dataset categorizes projects by six specific types, including HLM, OMHM, and NPO housing, and has been updated annually since the early 2000s.

Use Cases

• Analyze the distribution and count of housing units across the six project types (HLM, OMHM, SHDM, NPO, Coop, Anjou80) to assess supply.
• Map the geographic locations of non-profit (NPO) and cooperative (Coop) housing projects using the provided spatial files (SHP, GEOJSON).
• Track annual changes in the inventory of public housing (HLM) and affordable housing (OMHM) managed by the Office municipal d'habitation de Montréal.

Strengths

• Inventory is maintained on an annual basis, providing time-series data since the early 2000s.
• Data is categorized by six distinct, well-defined project types for clear analysis.
• Available in multiple formats including CSV for tabular analysis and SHP/GEOJSON for spatial mapping.

Limitations

• Row count and specific column structure are unknown, limiting precise assessment of dataset scale.
• Data is built from sources of varying quality, which may introduce inconsistencies.
• Scope is limited to the Montreal agglomeration, not the broader province or country.
