Labor and Employment Quebec 3 Minutes Read · published May 24, 2026 Flag of Quebec

In Longueuil, Quebec, workers and the public who observe unsafe conditions at a workplace can pursue remedies through provincial and municipal channels. Start by documenting the hazard and notifying your employer or site supervisor; if the risk is imminent or the employer does not act, contact the provincial workplace safety authority for inspection and enforcement.[1] This guide explains who enforces workplace safety, how to file a complaint, typical outcomes, and what to expect from inspections in Longueuil.

Who is responsible

The principal authority for occupational health and safety in Quebec is the Commission des normes, de lE9quitE9, de la santE9 et de la sE9curitE9 du travail (CNESST). The City of Longueuil enforces municipal bylaws that may affect public works, municipal building sites, and local permits.

When to file

  • If there is an imminent danger to life or health, do not delay: evacuate and call emergency services.
  • When an employer fails to address a known hazardous condition after being notified.
  • When unsafe practices persist despite workplace controls or refused corrective orders.
Document hazards with photos, dates and witness names before filing.

How to file a complaint

  • Notify your employer or the immediate supervisor in writing and keep a copy.
  • Collect evidence: photos, logs, incident reports, and contact information for witnesses.
  • Contact the CNESST to request an inspection or to obtain guidance on rights and remedies.[1]
  • If the concern involves municipal property, contact Longueuil By-law Enforcement via the CityE280 9s service request channels (see Help and Support / Resources).

Penalties & Enforcement

Enforcement and penalties depend on the governing instrument: provincial occupational health and safety legislation is enforced by CNESST; municipal bylaws are enforced by City of Longueuil officials for matters on municipal property or related to permits.

  • Monetary fines: not specified on the cited page for CNESST enforcement; municipal bylaw fines vary by regulation and are not specified on the cited municipal pages.
  • Non-monetary orders: CNESST may issue orders to stop work, corrective orders, or directives to remediate hazards; municipal officers may issue orders under local bylaws.
  • Escalation: first, corrective orders; repeat or continuing non-compliance may lead to administrative penalties or referral to courts — specific ranges and escalation steps are not specified on the cited page.
  • Seizure or stoppage: in imminent-danger situations, inspectors can require immediate stoppage of work.
  • Appeals and review: decisions and orders by CNESST inspectors are subject to review or appeal as provided by CNESST processes; time limits for appeals are not specified on the cited page.
