Toronto’s trees are more than just greenery—they are vital urban infrastructure. They cool our neighbourhoods, clean our air, support biodiversity and make our city more resilient to climate change. Mature trees, in particular, provide irreplaceable ecological benefits that young trees take decades to match.

In 2021, City Council reaffirmed its commitment to achieving 40 per cent tree canopy cover by 2050. While planting new trees is essential, protecting the ones we already have, especially large, healthy, mature trees, is the foundation of a thriving urban forest.
