Local tree-rule guide
Quebec City tree rules
Local tree/bylaw source reviewed; confirm ownership, size and property area.
The local rule
Québec City regulates tree felling and generally requires municipal authorization before a tree is cut under the circumstances described in its rules.
The City uses a project-specific permit assistant because accepted reasons and requirements can vary with the tree, property and proposed work.
Local exceptions and conditions
Scope and protected trees
- Québec City's official tree page says a certificate of authorization is generally needed to fell a tree on private land.
- Its urban-planning harmonization regulation defines 'abattage' broadly: taking at least half the crown or roots, or causing the tree's death, can be treated as felling.
- A contractor cannot necessarily avoid the certificate by leaving a bare trunk standing.
- The City's plain-language page does not give one universal diameter threshold applicable to every property or district; use its permit assistant and the applicable arrondissement rules.
- This corrects the narrower public-tree impression in the earlier guide.
Applications and timing
- Allowed reasons listed by the City include a dead, dangerous or declining tree, disease or insect transmission, a tree obstructing authorized construction, one interfering with another tree's growth, and ash.
- The City still instructs owners to wait for the certificate even when one of those reasons applies.
- Identify the proposed tree with ribbon or another visible marker so the urban forestry team can assess it during a courtesy visit.
- A garage or extension may also need its building approval.
- The City gives no fixed all-case turnaround on this page; inspection and missing documents can affect timing.
Enforcement and exceptions
- The public instructions warn that removing 50 per cent of a tree's crown can be an unlawful felling, so severe topping is a realistic enforcement scenario even without a stump.
- The exact monetary sanction depends on the applicable bylaw and property, rather than a citywide figure published on the permit summary.
- A landmark specimen or tree in a protected natural or heritage setting can require an additional site check; the linked page does not state a separate 'heritage tree' diameter.
- Cross-check the official regulation and parcel constraints before concluding that a particular species or size is exempt.
Accepted grounds for removal
- The City's accepted grounds for a felling certificate are narrower than a homeowner's preference for an open view.
- A dead, declining or dangerous tree, pest or disease transmission, a permitted building obstruction, interference with another tree's growth, and an ash are listed reasons.
- The page expressly says a qualifying reason is not permission to cut before the certificate arrives.
- If a garage addition is the reason, the building authorization and tree certificate need to describe the same footprint.
- Tagging the tree in the yard helps the urban forestry team's courtesy visit distinguish it from a neighbour's tree or another specimen on the lot.
Pruning and injury
- Pruning is a separate practical risk in Québec City.
- Its public instructions require directional cuts that preserve a suitable live branch, and warn that removing half the crown can count as felling.
- A contractor who leaves a topped trunk has not necessarily avoided the certificate.
- For a tree near an older wall or a root-damaged drain, record condition and obtain the City's property-specific answer through the permit assistant or 311 instead of inventing a universal centimetre cutoff.
- An elm or ash with disease may also have a City support or disposal route, while a tree on a public strip calls for municipal management.
- The cited service does not promise a uniform processing period; an inspection or additional building document can change the schedule.
Before work starts
- Ownership: check the property line. Public and boundary trees may follow a different process.
- Site context: review any development approval, covenant or protected-area conditions.
- Work requirements: confirm any permit, exemption or protection requirements that apply to the planned work.
