London Park Bylaw: Invasive Species Permit Rules

Environmental Protection Ontario 3 Minutes Read · published February 12, 2026 Flag of Ontario

In London, Ontario, removing invasive plants or animals from city parks usually requires approval to protect public safety, habitat and municipal assets. This guide explains when a permit is needed, who enforces park and bylaw rules, what penalties may apply, and step-by-step actions to request permission or report unauthorized removal in London parks.

When a permit is required

Work that alters vegetation, disturbs soil, or uses mechanical or chemical control in a City-owned park commonly falls under the park permit or work-in-park rules. Routine private removal on the park edge that does not damage trees or infrastructure may be allowed, but removal of larger stands, cutting of trees, or use of herbicides generally needs written approval.

Apply for a park permit or an approved maintenance plan via the City of London park permits page Park permit information[1].

Penalties & Enforcement

Enforcement is typically by the City of London By-law Enforcement and Parks Operations. Specific monetary fines, escalation schedules, and continuing offence amounts are not clearly specified on the cited bylaw summary page and must be confirmed with the City of London by-law office or the consolidated bylaw text.[2]

Unauthorized removal in a park can lead to orders to restore vegetation and possible fines.
  • Fines: not specified on the cited page; check the City of London consolidated bylaw or contact By-law Enforcement.[2]
  • Escalation: first, repeat and continuing offence ranges are not specified on the cited page; enforcement may include daily continuing fines or separate charges.
  • Non-monetary sanctions: restoration orders, stop-work orders, seizure of equipment, and court prosecution are enforcement options under municipal bylaws.
  • Enforcer and inspections: By-law Enforcement, Parks Operations and municipal inspectors carry out inspections and issue orders; complaints route through official City complaint pages.
  • Appeals and review: appeal routes depend on the issuing order or ticket; time limits for appeals are not specified on the cited summary and should be confirmed with the issuing office.
  • Defences: authorized permits, reasonable excuse, or contractor authorizations may be valid defences if documented.

Common violations and typical outcomes

  • Cutting or removing trees without approval — may trigger restoration orders and fines.
  • Using herbicides in a park without an approved plan — may be prohibited and lead to stop-work orders.
  • Unauthorized mechanical removal of wetland vegetation — could result in prosecution and remediation requirements.

Applications & Forms

The City publishes park permit guidance and application steps on its park permits page; specific permit names, form numbers, fees and submission methods are available there. If a dedicated invasive-species removal form is not listed, applicants should use the general park permit application and attach a management plan or contractor details.[1]

If a permit is required, submit a clear work plan and maps to speed review.

How-To

  1. Identify the species and map the area to be treated; document size, location and proximity to trees or water.
  2. Contact the City of London parks permits office to confirm whether a permit or an approved maintenance plan is required.
  3. Prepare and submit a park permit application with a treatment plan, contractor credentials, proposed methods, and any herbicide labels if chemicals are planned.
  4. Await written approval and follow any conditions; schedule inspections if required and retain records of disposal and treatment.
  5. If you observe unauthorized removal, report to By-law Enforcement and provide photos, location and time to support enforcement.
Keep records of permits, maps and contractor authorizations for at least one year after work completion.
