Illicit Discharge Bylaw in Québec - How to File a Complaint

Utilities and Infrastructure Quebec 3 Minutes Read · published February 12, 2026 Flag of Quebec

In Québec, Quebec, municipal rules govern illicit discharges to storm sewers, rivers and public drainage. This guide explains how the city addresses unauthorized releases, who enforces the rules, and the practical steps to file a complaint or report a spill. Use the official municipal contact and provincial reporting resources to submit evidence, photos and location details so inspectors can act quickly. If a specific bylaw section or monetary penalty is needed for court or prosecution, request the enforcing department’s citation when you file your complaint.

Penalties & Enforcement

The City of Québec enforces prohibitions on illicit discharges through its bylaw framework and inspection teams; municipal staff may issue orders, require remediation, and refer matters to courts. Specific fine amounts and graduated penalties are not specified on the cited municipal pages; request the exact bylaw citation from the enforcing office when you report an incident[1]. The provincial government also maintains spill-reporting and pollution rules that may apply in parallel to municipal action[2].

For incidents that trigger provincial jurisdiction, use the provincial reporting forms or hotline listed by the government[2].

  • Record the complaint and assign an inspection priority based on risk to public health and waterways.
  • Conduct on-site inspection and collect evidence (samples, photos, witness statements).
  • Issue orders or notices to stop the discharge and require cleanup when needed.
Keep copies of all communications and photos for enforcement and appeals.
