Public Safety Quebec 3 Minutes Read · published May 24, 2026 Flag of Quebec · By Daniel Roy

In Longueuil, Quebec you can begin a complaint about police conduct by contacting the local police service and, for certain incidents, the provincial oversight body. Complaints may concern behaviour, use of force, discrimination or procedural errors. Start by documenting date, time, location, officer identification and any evidence such as photos or witness names. For incidents causing serious injury or death, a provincial investigative body may have jurisdiction [1]. This guide explains who enforces complaints, typical outcomes, how to file online, and what to expect in review and appeal.

Keep a clear, dated written record of events and evidence before filing.

Penalties & Enforcement

Police conduct complaints are addressed through administrative discipline, internal investigations, and—when applicable—criminal prosecution. Specific monetary fines for police misconduct are generally not the typical sanction; instead, outcomes focus on disciplinary measures and possible criminal charges. Where exact penalties or fines would apply under municipal bylaws or provincial law, those amounts are not specified on the cited page.

  • Enforcer: Service de police de l'agglomération de Longueuil (internal professional conduct unit) or the provincial investigative office for serious incidents.
  • Sanctions: suspension, reprimand, dismissal, referral for criminal charges—specifics not specified on the cited page.
  • Inspection and review: internal review and disciplinary hearings; provincial review for designated incidents.
  • Monetary penalties: not typically used for officer discipline; details not specified on the cited page.
Administrative discipline can include suspension with or without pay depending on the investigation.

To file a complaint you usually complete a written complaint form with the police service or submit an online complaint where offered. The official complaint form name or number is not specified on the cited page; contact the service for the current form and submission method.
