Do I need a permit to prune a tree?

Routine pruning is often treated differently from tree removal, but rules vary by municipality, location, and the extent of the work. Check with your municipality.

Why should I avoid topping a tree?

Severe cuts can create large wounds and encourage weaker regrowth. An arborist can recommend pruning suited to the tree.

When should a mature tree be inspected?

Ask for an assessment after a storm, when a major branch breaks, or if you notice a crack, cavity, or decline.

Can I prune a tree near power lines?

Stay away from the lines. Have the network identified and contact Hydro-Québec or the wire owner for instructions.

Service guide

Responsible tree pruning in Mirabel and the Laurentians

Pruning can improve safety around a tree and preserve its natural form. The work depends on the species, branch condition, and goal.

Plan my project Check my municipality

Understanding the work

Responsible pruning selectively removes dead, diseased, or interfering branches while respecting the tree’s structure. Topping and severe cuts can weaken a tree and encourage weak regrowth.

When should I request an assessment?

Dead or damaged branches above a walkway or other frequently used area.
Branches rubbing against a roof or exterior wall.
Low branches obstructing a path or sightline.
A structural assessment after freezing rain or strong winds.

Methods and equipment

Safety pruning and sanitary removal of deadwood.

Targeted clearance around a building or walkway.

Structural pruning suited to the tree’s species and age.

When should the work be scheduled?

The suitable time varies by species and pruning objective. Local restrictions may also apply to ash trees; check municipal guidance before scheduling work.

What affects the cost

An estimate depends on the actual job. Here are details to provide:

The number and height of trees, and site access.
The volume of branches to remove and the difficulty of the cuts.
Ground-level obstacles and proximity to buildings.
Chipping and removal of debris.

Before work near power lines

Safety first: are branches near electrical lines?

Never touch the tree or wires. Choose the type of line to see what to do. If you cannot identify it with confidence, keep your distance and contact Hydro-Québec.

If a wire is down, sparks are visible, or there is immediate danger, move at least 10 metres away and call 911.
