Toronto Green Roof Bylaw

The Toronto Green Roof Bylaw requires new buildings in the city to include green roofs—vegetated roof surfaces that help improve air quality, reduce heat, and manage stormwater. Typically, buildings over a certain size must dedicate a portion of their roof space to greenery, which can include plants, gardens, or other natural features. This regulation encourages sustainability, energy efficiency, and environmental benefits, while also enhancing urban aesthetics. Compliance helps Toronto meet its climate goals and creates healthier, more resilient urban spaces.
