Quebec CNESST Regulations Resource Hub

Welcome to the Preventis CNESST Resource Hub. In Quebec, occupational health and safety is governed by the Commission des normes, de l'équité, de la santé et de la sécurité du travail (CNESST). Staying compliant with Quebec's specific health and safety laws—especially following the major modernization under Bill 59 (Law 27)—is essential for protecting your workers and avoiding severe financial penalties.
Whether you are an employer, supplier, or worker, this hub provides you with comprehensive, up-to-date information on everything from interpreting safety data sheets to understanding national regulatory updates.

Whether you are navigating the new Prevention Program mandates, setting up a Health and Safety Committee, or ensuring your workforce has the right training, this hub provides you with comprehensive, up-to-date information on managing OHS compliance in Quebec.

Explore Our CNESST Information Center

Navigating Quebec's specific health and safety laws can feel complex. Explore our detailed guides to learn how CNESST regulations are implemented, managed, and enforced across the province.

1. Employer & Worker Responsibilities (LSST)

Occupational health and safety in Quebec is based on the parity principle—a shared responsibility. Learn the distinct legal duties assigned to employers, supervisors, and workers under the Act respecting occupational health and safety (LSST), including the worker's fundamental right to refuse dangerous work.

2. The Prevention Program & Action Plan (Bill 59 Updates)

As of October 2025, the rules have changed. Learn about the mandatory requirement for businesses with 20 or more employees to develop, implement, and annually update a comprehensive Prevention Program. For businesses with fewer than 20 employees, discover how to build your legally required Action Plan.

3. Health and Safety Committees (CSS) & Representatives

Bill 59 expanded the requirement for joint occupational health and safety committees. Explore the rules for establishing a CSS, the legal mandate to appoint trained Health and Safety Representatives (or Liaison Officers for smaller teams), and their critical role in workplace risk assessment.

4. Managing Psychosocial Risks & Workplace Violence

Quebec's modernized OHS regime now explicitly legally requires employers to identify, evaluate, and prevent psychosocial risks (PSRs), including psychological harassment, sexual violence, and domestic violence in the workplace (even for remote workers). Learn how to integrate these elements into your mandatory policies.

5. Mandatory OHS Training in Quebec

Who needs training, and what must be covered? Understand the CNESST's strict requirements for worker onboarding, specific hazard training (such as WHMIS/SIMDUT), and the legally mandated paid theoretical training required for all Health and Safety Committee members and representatives.

6. Workplace Injury & Accident Reporting (LATMP)

Accidents happen. Learn the strict protocols governed by the Act respecting industrial accidents and occupational diseases (LATMP). From providing immediate first aid and transportation, to filling out the Register of Accidents and navigating the CNESST claims and return-to-work process.

Why Complete CNESST Compliance Matters

A proactive approach to health and safety is no longer just a best practice in Quebec—it is the law. An effective CNESST compliance program ensures that:

Workers are Protected

Employees have a legally protected right to work in an environment that safeguards their physical and psychological well-being.

Fines are Avoided

Bill 59 significantly increased the fines for non-compliance, with penalties for repeat offenses reaching up to $12,000.

Premiums are Managed

A strong prevention program reduces workplace incidents, which directly impacts and lowers your annual CNESST insurance premiums.

Ready to Streamline Your Quebec Safety Compliance?

You don't have to navigate the complexities of Bill 59 alone. Preventis offers industry-leading training, consulting, and specialized OHS software designed specifically to help Quebec businesses build compliant Prevention Programs and manage their daily safety operations.
