Local tree-rule guide
Brossard tree rules
Authorization certificate required for a tree ≥10 cm diameter measured at 1.3 m; ash-tree rules are also separately regulated.
The local rule
Brossard requires an authorization certificate before felling a covered private-property tree and defines the tree category in its municipal guidance.
The City identifies accepted reasons such as a dead, incurably diseased, dangerous or project-conflicting tree and can require professional documentation for some cases.
Application details
Brossard requires a certificate before most regulated tree removals
- Brossard’s current page sets a clear trigger: a certificate is required to fell a tree with a trunk diameter of 10 cm or more measured 1.30 m above ground.
- The same page also explains which reasons qualify, what evidence is needed and how replacement works.
A certificate is required for removal of a tree 10 cm or more in diameter at 1.30 m. The City also separately regulates the felling or pruning of ash trees.
The City lists dead trees, incurable disease, unavoidable conflict with authorized work, danger where removal is the only corrective measure, qualifying nuisance and prohibited species. Leaves, flowers, fruit, insects/animals, blocked light/view, sap and pollen are expressly not treated as qualifying nuisance reasons.
For a diseased or dangerous tree, the required report must be signed by a forestry engineer, an arborist certified by a recognized organization such as ISA, or a horticulturist.
All applications need tree photos. Depending on the property/case, Brossard can also require a professional report, condominium-syndicate letter, clearing plan for protected woodland/forest corridor, or replacement-tree planting plan.
A replacement tree must be planted within 12 months after the removal certificate is issued, subject to the City’s planting requirements.
After an emergency such as storm-related tree failure, removal can occur before the certificate, but the application must be submitted within seven days.
Brossard currently warns that felling without the required certificate can lead to a minimum $1,000 fine. Check the current fee portal separately for application charges rather than relying on older tariff schedules.
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.
