Multi-Year Canopy Explorer
How to use this tool
Select multiple years from 2012 to 2023 to compare canopy coverage evolution across Montreal boroughs. The multi-year view shows long-term trends: which areas are gaining tree cover through planting programs and which are losing canopy to development, storms, or disease. Use the timeline slider to animate changes over the decade.
Why it matters
Long-term canopy tracking reveals the real impact of municipal greening policies, development pressures, and natural events like ice storms on Montreal's urban forest. Some boroughs have made significant gains through aggressive planting programs, while others have lost canopy to construction and emerald ash borer infestations. This decade-long perspective helps residents evaluate whether their neighbourhood is trending greener or losing ground.
