What Is the CNESST?
The CNESST, or Commission des normes, de l’équité, de la santé et de la sécurité du travail, is the public body responsible for administering several workplace laws in Québec.
Since 2016, it has brought together three essential areas of responsibility that were previously managed by separate organizations:
- Labour standards, formerly administered by the Commission des normes du travail
- Pay equity, formerly administered by the Commission de l’équité salariale
- Occupational health and safety, formerly administered by the CSST
The CNESST therefore serves as a central point of contact for employers and workers, covering working conditions, pay equity, and the prevention of workplace accidents and occupational diseases.
The CNESST’s Main Areas of Responsibility
1. Labour standards
The CNESST administers Québec’s Act respecting labour standards. It helps ensure that employers comply with minimum employment conditions related to wages, vacation, hours of work, leaves and termination of employment.
It also receives complaints from employees when applicable labour standards are not respected.
2. Pay equity
The CNESST also administers the Pay Equity Act, which is intended to address compensation differences associated with predominantly female and predominantly male job classes performing work of equivalent value.
It supports organizations in meeting their compliance obligations and may require corrective measures when applicable requirements are not respected.
3. Occupational health and safety
The CNESST oversees the application of the Act respecting occupational health and safety and the Act respecting industrial accidents and occupational diseases.
Its responsibilities include:
- Preventing workplace accidents and occupational diseases
- Managing employer financing and contributions
- Providing compensation and rehabilitation support to workers affected by employment-related injuries or illnesses
For Workers
The CNESST provides an important avenue of recourse for workers.
An employee who believes that their labour standards rights have not been respected—for example, regarding wages, leaves, psychological harassment, termination of employment or collective layoffs—may be able to file a complaint with the organization.
In the event of a workplace accident or occupational disease, the CNESST may provide income-replacement benefits, cover certain treatment-related costs and support the worker’s rehabilitation and return to work.
For Employers
For employers, the CNESST acts as both a resource and a regulatory body.
It:
- Provides information about legal obligations related to employment, occupational health and safety, and pay equity
- Offers tools and training to support workplace management and prevention
- May conduct investigations and impose corrective measures or penalties when applicable laws are not respected
Québec’s occupational health and safety system is financed through employer contributions, which are determined according to factors such as industry risk and claims experience.
A Prevention and Collaboration Mandate
Beyond enforcing legislation, the CNESST plays an important role in prevention.
It supports workplaces in developing prevention programs, training initiatives and practices that promote safe, healthy and equitable working environments.
It also contributes to collaboration among government, unions and employer associations in response to changing workplace realities.
In Summary
The CNESST is a central institution in Québec’s labour environment.
It:
- Protects workers’ rights
- Defines and oversees employer obligations
- Supports prevention, compensation and rehabilitation in occupational health and safety
- Administers Québec’s pay equity framework
It is a key pillar of workplace regulation in Québec, combining worker protection with organizational responsibility.
