Main bylaws of the City of Chambly regarding trees

Tree Removal Maintenance Planting

Tree Removal

A certificate of authorization (tree cutting permit) is required to fell any tree with a diameter exceeding 10 cm, measured at 1.2 meters above ground level.

A certificate of authorization (permit) may be issued by the City of Chambly under the following circumstances:

• The tree is dead or diseased;
• The tree is diseased with no possibility of recovery;
• The tree is an ash tree;
• The tree is a nuisance and causes damage to foundations, underground pipes, or poses a risk of falling large branches;
• The tree is located where a new construction or an expansion of an existing structure is planned;
• The tree hinders the growth and development of neighboring trees.

Certain sectors do not require a tree cutting permit if the tree to be cut is located in a side or back yard. We strongly suggest contacting the city to verify if a permit is required in your sector, regardless of the tree's location, to ensure compliance with municipal bylaws.

Maintenance

The natural shape of the tree must be preserved during pruning or trimming work in the City of Chambly.

Topping trees is prohibited within the territory of the City of Chambly.

Partial cutting and clear-cutting are also prohibited.

During pruning, a maximum of 30% of the branches may be removed.

It is prohibited to compromise the integrity of a tree with a diameter greater than 10 cm, measured at 30 cm from the ground, located in the front yard, by altering the roots, bark, trunk, or branches.

Planting

The front yard must have at least one tree. Exceptions apply depending on the sector where the minimum may be higher; we strongly suggest checking with the city. Additionally, one extra tree is required for every 500 square meters of lot area.

Every removed tree must be replaced by another tree, even if the minimum number of trees is met after cutting, unless the lot has no more room for planting or the property already includes at least 2 trees, plus 2 other trees per 500 square meters of lot area.

Any tree cutting must be replaced by planting a tree within one year following the cutting, respecting the following provisions and characteristics:

• The tree must have a minimum trunk diameter of 50 millimeters at 1.2 meters above ground level;
• The replacement tree can be a conifer or a deciduous tree;
• The replacement tree must be located in the front setback, unless the minimum number of trees required by the city in the front setback is met after cutting;
• At maturity, the tree must reach a minimum height of seven (7) meters. Any species below this height is considered a shrub and, in this case, cannot be considered a replacement tree.

The following tree species must be planted more than 15 meters from any street line, public easement for sewer and water mains, and your home:
