Tree removal rules in Laval, QC
A plain-English guide to what Laval publishes about tree removal and protection. The first question is whether the rule covers your private tree at all—not every City tree bylaw is a private-yard permit bylaw.
CITY-SPECIFIC SUMMARY
What Laval actually regulates
Laval’s published tree and bylaw rules, in plain English:
Laval requires an authorization certificate before felling a covered tree on private property, including when removal was recommended by a utility.
The City sets tree-size definitions and accepted reasons for removal and generally requires an authorized tree to be replaced.
Regional context
Laval uses a municipal certificate/permit framework that can differ from neighbouring Quebec municipalities. See the Quebec tree-rule overview and rely on the Laval source for local thresholds and accepted reasons.

Extra requirements namedFor Laval, also confirm ownership/boundary status, development conditions and any protected-area overlay before cutting.
LOCAL DECISION PATH
What to verify before removing a tree in Laval
Laval publishes private-tree controls, so the first job is to identify whether this specific tree is protected before booking removal.
2. Separate private, public and boundary trees
The Laval source identifies private-tree rules; boulevard, City-owned and shared-boundary trees can follow a different process.
3. Apply before removal
If the Laval source requires authorization, wait for the municipal decision and read the permit conditions before cutting.

Construction and tree protection in Laval
The source reviewed for Laval does not justify assuming that ordinary yard construction is always outside tree rules. If work could affect a City tree, boundary tree, protected area or a tree retained through development approval, confirm the municipal requirements before excavation or root disturbance.

Open Laval’s rule ↗City / boulevard tree
Do not self-authorizeIf the trunk is on Laval municipal land, a boulevard or road allowance, do not self-authorize pruning or removal. Confirm ownership and use the municipality’s tree process.
Check ownership rules ↗Boundary tree
Ownership mattersIf the trunk sits on or very near a property line in Laval, confirm ownership before work. Municipal tree rules do not replace private-law rights involving a co-owned or neighbouring tree.
Check local application rules ↗Development site
Often stricterIn Laval, development work such as demolition, additions or subdivision can bring tree-retention, arborist or replacement requirements into the approval path; use the linked development-tree source for the site.
