Environmental Protection Quebec 3 Minutes Read · published February 11, 2026 Flag of Quebec

Owners in Montréal, Quebec who want to remove invasive plants or vegetation from private property must follow municipal rules and any provincial guidance that apply. This article explains when a municipal permit is needed, who enforces the rules, how to apply, and what to expect for inspections, fines and appeals. It summarizes official City of Montréal and Quebec government steps so owners can act quickly, safely and legally when addressing species like invasive shrubs, vines or reedbeds on their lots.

When a permit is required

Removal of invasive plants may still require municipal authorization if the work affects trees, protected vegetation, public boulevard areas, or soil and watercourses. Check the City of Montréal permit pages for rules on trees and vegetation before starting work.[1]

Always verify whether a tree permit or boulevard authorization is required before removing large plants.

Penalties & Enforcement

The City of Montréal enforces bylaws on vegetation and site disturbance through its by-law enforcement teams. Specific monetary fines and escalation steps depend on the controlling bylaw and the facts of the case; if a precise fine is not published on the cited page, the amount is not specified on the cited page.[2]

  • Fine amounts: not specified on the cited page; consult the controlling bylaw or enforcement notice for exact penalties.
  • Escalation: first and repeat offences and continuing offences are addressed per the bylaw; ranges are not specified on the cited page.
  • Non-monetary sanctions: orders to stop work, remediation orders, seizure of materials, and court proceedings may be used.
  • Enforcer and complaint pathway: contact Montréal by-law enforcement or report issues via official City channels for inspection and complaint intake.[2]
  • Appeals: appeal routes or judicial review follow municipal procedure; specific time limits are not specified on the cited page and should be confirmed with the enforcement office.
Failing to obtain required permits can lead to orders to restore the site and enforcement actions.

Applications & Forms

  • Permits for work affecting trees or municipal boulevards: see the City of Montréal permit pages for application forms and instructions.[1]
  • Deadlines: submission timelines and processing times are set by the City; specific deadlines and fees are listed on the applicable permit page or form.
  • Submission method: most municipal permit requests are made online or at the borough office as indicated on the official permit page.

If the invasive removal may affect waterways, wetlands, or species protected under provincial rules, consult Quebec government guidance before proceeding.[3]

How to plan the removal

  • Identify species and extent of infestation and whether trees or boulevard plants are involved.
  • Check municipal permit requirements and submit any required applications.
  • Hire licensed contractors for significant removals to ensure safe disposal and erosion prevention.
  • Keep records and photos of the site and any permits received.
Proper disposal and remediation reduce the chance of re-infestation and enforcement action.
