The Urban Tree Canopy

The Benefits of Trees

Trees are some of the most important assets in any neighbourhood, delivering a broad range of environmental, social, and economic benefits that improve everyday life for residents. As vital green infrastructure, they help address climate change, enhance air quality, and support local biodiversity. Trees also add beauty and comfort to public spaces, providing shade and inviting areas for recreation and community connection.

Mature trees help lower energy use by shading building sin summer and reducing wind exposure in winter. This can decrease the need for air conditioning and heating, saving money and reducing overall energy demand. 

Trees improve air quality by filtering pollutants such as dust, smoke, and exhaust particles from the air. They also absorb gases like nitrogen dioxide and ozone, helping create healthier neighbourhoods. 

Tree-lined streets and green space encourage walking, cycling, and outdoor recreation. Access to shaded, attractive areas also supports active transportation and can reduce heat-related health risks. 

Urban fruit and nut trees can provide locally grown food for residents and wildlife by providing shelter, nesting areas, and food. Native tree species are especially important for supporting local ecosystems.

A mature canopy creates habitat for birds, pollinators, and other wildlife by providing shelter, nesting areas, and food. Native tree species are especially important for supporting local ecosystems. 

Trees add character, colour, and seasonal interest to streets and parks. A healthy canopy contributes to vibrant neighborhoods and creates welcoming public spaces. 

Large trees provide natural shade that cools sidewalks, parks, and homes. This reduces the urban heat island effect and helps make outdoor spaces more comfortable during the warmer months. 

Access to trees and green spaces can reduce stress and support overall wellbeing. Natural environments are linked to improved mood, better focus, and a stronger sense of community connection. 


Homes and neighbourhoods with established trees are often more desirable and can have higher property values. A mature canopy can also enhance curb appeal and neighbourhood pride. 

Trees help manage rainfall by intercepting water in their leaves and branches and absorbing it through their roots. This reduces runoff lowers the risk of flooding, and supports healthier waterways. 

Tree roots help stabilize soil and reduce erosion, while canopy cover can protect pavement from extreme heat and weathering. Strategic tree planting can also help shield buildings and public spaces from wind and sun exposure. 


Trees absorb carbon dioxide as they grow and store it in their trunks, branches, and roots. Maintaining and expanding the urban tree canopy helps reduce greenhouse gas levels and supports climate action goals. 

The Role of Community in Urban Forestry

Supporting our urban tree canopy is a shared effort—and residents play a vital role, especially in communities where planting space is limited by impervious surfaces, underground utilities, and a lack of available public land. While the Town continues to plant and care for trees where possible, many of the best opportunities to grow the canopy are on private property.

Residents can make a meaningful impact by planting a tree in their yard and helping it thrive over time. A single well-placed tree can provide shade, reduce cooling costs, improve air quality, support wildlife, and make neighbourhoods more comfortable and beautiful.

Just as important is protecting the trees we already have. Mature trees provide the greatest benefits, and preserving them through proper care, maintenance, and thoughtful decisions during landscaping or construction helps ensure the canopy remains healthy for future generations.

Together, small actions on individual properties add up—strengthening our community forest and helping our neighbourhoods stay greener, cooler, and more resilient as the climate changes.
