Tree removal rules in Blainville, QC
A plain-English guide to what Blainville 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 Blainville actually regulates
Blainville’s published tree and bylaw rules, in plain English:
Blainville requires an authorization certificate to fell a tree that meets the City’s protected diameter definition.
The City’s current material uses a 10 cm diameter measured at 1.4 m for the authorization rule and also treats severe crown or root removal as tree felling in specified circumstances.
Regional context
Blainville uses a municipal certificate/permit framework that can differ from neighbouring Quebec municipalities. See the Quebec tree-rule overview and rely on the Blainville source for local thresholds and accepted reasons.

LOCAL DECISION PATH
The local checks that change the answer in Blainville
Blainville’s published material needs to be read by tree ownership, location and project context rather than through one Canada-wide rule.
2. Check whether the property has special controls
In Blainville, development applications, environmental areas, riparian/ravine lands, covenanted trees or planning approvals can create tree-protection rules even when an ordinary private-yard tree is not covered by a blanket bylaw.
3. Use the published measurement only where it applies
The local material includes 10 cm. Make sure that number applies to this ownership/location category before using it.
4. Keep public-tree work with the municipality
If the tree is on a Blainville road allowance, boulevard, park or other municipal land, use the municipal process before pruning, root disturbance or removal.

When construction can change the tree-rule answer in Blainville
Blainville’s local material identifies development, construction or tree-protection-zone issues. Before excavation, grading, a driveway, utility trench, retaining wall, pool or building work near a tree, check whether the municipal rule treats root/soil disturbance as regulated injury.

Check ownership rules ↗Boundary tree
Ownership mattersIf the trunk sits on or very near a property line in Blainville, confirm ownership before work. Municipal tree rules do not replace private-law rights involving a co-owned or neighbouring tree.
