Admissibility of a claim

In the event of a work accident or occupational disease, workers must fill out the Worker's claim form to receive benefits or claim certain expenses. After a claim is filed, the CNESST examines its admissibility.

In the case of a claim for an occupational disease, workers must also fill out the appendix to the Worker’s claim form corresponding to their medical situation.

Eligibility criteria

Fill out the Worker's claim form

This form contains specific questions relevant to the examination of the claim. It must be filled out and accompanied by the corresponding appendix in the case of a claim for an occupational disease. Therefore, it is very important that the worker provide the CNESST with information that is complete, accurate and relevant to the examination of their claim. For example, they may enclose a medical certificate, receipts or prescriptions.

File the claim within the required time period

The worker has 6 months to send us their Worker's claim form when they have a work accident or believe they are suffering from an occupational disease. Therefore, it is important to file the claim as soon as possible.

For a work accident, this period begins when the employment injury occurs.

In the case of an occupational disease, this period begins when one of the following situations occurs:

  • the worker's healthcare professional diagnoses the disease
  • the worker becomes aware of the probable relationship between their disease and their work

Undergo medical examinations

The worker is obliged to report for medical examinations and to comply with all treatments prescribed by the treating healthcare professional.

The employer and the CNESST may request an independent medical assessment. The employer and the CNESST may request an assessment by a healthcare professional other than the one the worker initially consulted.

Claim eligibility analysis

For the claim to be admissible, it must be established that the worker has an employment injury. The injury must be related to their work.

Whether the claim is accepted or rejected, when the CNESST renders its decision, it informs the worker and the employer in writing. If the claim is admissible, the worker will be able to receive benefits and claim certain expenses.

If the worker disagrees with the decision rendered by the CNESST, they may contest the decision.
