Your obligations

The 4 pillars of compliance Law 27

The prevention approach must be documented and adapted to the risks present in each establishment.

1. Identify and analyze

Identify health and safety risks, including work-related psychosocial risk factors, then set your priorities.

2. Plan and prevent

Develop the required action plan or prevention program, with measures, priorities and timelines adapted to your context.

3. Involve

Involve workers and the mechanism applicable to your establishment: liaison officer, health and safety committee or health and safety representative.

4. Track and document

Implement the measures, monitor their progress and keep the elements that demonstrate your approach.

Depending on the size of the establishment

The required prevention mechanism

19 workers or less

Action plan

The employer must develop, apply and update an action plan annually. A health and safety liaison officer must also be designated.

20 or more workers

Prevention program

The employer must develop, apply and update annually a prevention program, set up a health and safety committee and designate a health and safety representative.

Exceptions may apply, in particular when an establishment brings together 20 or more workers for less than 21 days, uses a multi-establishment approach or is part of a prevention mutual. Check your situation with the CNESST or a competent advisor.

Targeted FAQ

Your questions about Law 27

What do we mean by “psychosocial risks” (RPS)?

These are factors linked to the organization or working conditions that can affect physical or psychological health. Workload, support, recognition, harassment or violence may be part of the analysis depending on the context.

What is the role of the manager vs. HR?

The employer remains responsible for the process. HR and managers can help identify risks, apply measures and follow up. Workers and the applicable participation mechanism must also be involved in the process.

What happens in the event of non-compliance?

The CNESST can intervene according to its powers. Above all, a documented approach helps the organization demonstrate the risks identified, the measures chosen and their monitoring. For an interpretation specific to your situation, consult the CNESST or a competent advisor.
