Greening Priority Zones
How to use this tool
View the priority scoring map to identify where new tree planting and greening efforts would have the most impact on reducing heat wave risks in Montreal. Higher scores indicate areas with less canopy, more impervious surface, higher population density, and greater vulnerability to extreme heat. Use the borough filter to zoom into your area.
Why it matters
Not all planting locations deliver equal cooling benefits. Greening priority zones combine multiple vulnerability factors including canopy deficit, surface temperature, population density, and access to cooling centres. Targeting these zones for landscaping projects maximizes the return on every tree planted and every square metre of impervious surface converted to green space. For residents and community groups, this data guides where volunteer planting efforts and municipal investment should focus.
