Service quality complaints

We are committed to providing you with quality services and meeting your needs. If, despite our efforts, you are not satisfied with the services offered or provided by the CNESST, you may file a complaint.

Our commitment

The quality of our services is our top priority. Our Statement of Services sets out the values underlying our actions: respect, fairness and professionalism. We take various measures to ensure you are satisfied with our services. 

To ensure your satisfaction, we have developed a policy based on best practices for managing service quality complaints. 

Complaints are examined rigorously and impartially in accordance with our Statement of Services. When we receive your complaint, we will:  

  • call you back within 2 working days 
  • respond to your complaint within 10 working days 
  • take the necessary corrective measures, if possible 

How to file a service quality complaint

Your complaint must be filed, verbally or in writing, with the Quality Complaints Service. This service is separate from the CNESST’s other administrative units.  

Your complaint must include: 

  • your first name and surname 
  • your telephone number because this is how we will contact you 
  • additional information about the reasons for your complaint
