Mission and areas of activity
The Commission des normes, de l'équité, de la santé et de la sécurité du travail (CNESST) provides a single point of contact for workplace-related services in Quebec.
The CNESST is the body to which the Government of Quebec has entrusted the administration of the Act respecting occupational health and safety (AROH), and whose purpose is to eliminate hazards to worker health and safety at the source.
Furthermore, the Government of Quebec has an agreement with Health Canada to enforce the Hazardous Products Act (HPA) and related regulations. In Quebec, the CNESST oversees the implementation and enforcement of this legislation.
