Trees are a key architectural and aesthetic feature in Saint-Lambert. In our urbanized environment, they make our cities healthy, pleasant, and comfortable places to live by helping to control local temperatures and protect us from wind, improve air quality, and buffer the noise caused by wind and traffic. Trees also lessen our impacts on the environment and various ecosystems, for example, by reducing water runoff.

Tree policy

The Ville de Saint-Lambert recognizes the importance of trees in its urban environment, which is why it adopted a tree policy in September 2012. We all have a shared responsibility to preserve and improve our urban forest to ensure that future generations will be able to enjoy the quality of life to which they are rightfully entitled. The Tree Policy provides us with a management framework for working to conserve and develop this precious resource.

Municipal guide to choosing trees to plant

The municipal guide to choosing trees to plant (in French only), which was developed in keeping with the specific features of our territory, will promote the harmonious development of our urban forest by advising you about all aspects of a tree species. In addition to helping you choose the appropriate species, the guide incudes recommendations about tree planting, maintenance, protection, and cutting.

The guide is a practical tool that you should consult each time you have questions about trees on your property. Print copies are available for on-site consultation or on sale at a cost of $4 at City Hall and at the Urban Planning, Permits and Inspection Department.

Private trees

You do not need a permit to plant or maintain (prune) a tree on your property. However, a permit is required to fell a tree located on your property. To obtain a permit, contact the Urban Planning, Permits and Inspection Department at or 450-466-3277.

For complete details on the by-laws concerning trees on the territory of Saint-Lambert, visit the By-laws on trees page.

Public trees

Did you know that there are 13,600 public trees in Saint-Lambert? These trees can be found growing in rights-of-way, on private property, in parks and green spaces, on medians and islands, etc. These trees belong to the Ville de Saint-Lambert.

It is important to know that it is forbidden to prune or fell a public tree. If you believe that a tree is in need of maintenance, you are invited to contact the Environment Management division at or 450-466-3889, ext. 3316 to request an inspection.

Reporting damage to your property or possessions

Forestry Department

The Forestry Department handles the following:

  • Requests to fell a public tree;
  • Requests to prune a public tree;
  • Requests to inspect a public tree;
  • Requests to brace a public tree;
  • Requests to plant a tree in a public right-of-way.

You can send your requests at or 450-466-3889, ext. 3316. Due to the high volume of requests during the summer period, a certain amount of time may be required to process your request. Upon receipt of a request, an inspection of the tree will be carried out. You will then be notified whether or not the request is accepted.

How can I tell if my tree is private or public?

To find out if a tree on your property is yours (private) or the City’s (public), identify your property line using your certificate of location. If the center of the base of the tree is located within the public right-of-way, the tree belongs to the City.
