Heat Islands: Montreal Surface Temperature Differences for Climate Planning

Montreal's heat island polygons represent temperature differences on the ground surface, which can exceed 12°C. The data was produced for monitoring the City of Montreal's Climate Plan 2020-2030, aiming to improve urban planning and regulatory tools. It is published by the Government and Municipalities of Québec and last updated in July 2026.

Use Cases

• Analyze urban vulnerability to climate change based on heat island area mentioned as a monitoring indicator.
• Improve urban planning and regulatory tools based on temperature differences explained by land use and vegetation.
• Support annual accountability reporting for the Climate Plan based on the progress of its 46 actions.
• Visualize spatial patterns of surface temperature differences using the interactive heat island map.

Strengths

• Temperature differences can exceed 12°C, providing a clear metric for environmental impact.
• Data is tied to a specific policy framework, the City of Montreal's Climate Plan 2020-2030.
• Available in multiple geospatial formats (GEOJSON, GEOTIF, SHP) for different analysis tools.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to open_canada, focusing solely on Montreal.
