Commonly used forms - Form 8, Form CMS8 and FAF

In your work with the WSIB, you will frequently come across the Health Professional’s Report (Form 8), Health Professional’s Report for Occupational Mental Stress (Form CMS8) and the Functional Abilities Form (FAF).

Health Professional’s Report (Form 8)

When your patient suffers a work-related physical injury or illness and comes to see you, you must complete a 
, even if that patient first visited an emergency department. When your completed form arrives at the WSIB, we will scan it into the appropriate claim record and then send it for payment processing.


Use this form whether your patient states that a physical injury or illness is related to his or her work or whether you simply believe it is. Section 37 of the Workplace Safety and Insurance Act provides the legal authority for health care practitioners, hospitals and health facilities to submit, without consent, information relating to someone claiming benefits to the WSIB.

Your promptness in completing the form is critical to our ability to process and adjudicate your patient’s claim. Your patient, the employer and the WSIB depend on you.

Functional Abilities Form (FAF)

Functional Abilities Form (FAF) for Early and Safe Return to Work (PDF) provides information about your patient’s abilities. Your patient and their employer will use this information as a tool for planning a return to suitable work. A request for the form should only be initiated by the employer or your patient and, ideally, should only be completed when your patient is functionally able to return to work.

Only regulated health care practitioners can complete the Functional Abilities Form. You are required under the Workplace Safety and Insurance Act to provide us with any information we need about your patient’s health care.

We pay a set fee for completion of the WSIB Functional Abilities Form. For billing purposes, please fax or mail pages 2 and 3 to the WSIB. Read the Notice to Health care practitioners (PDF) for more information. (Note: Employers may request functional abilities information on a form of their own design. In this case, the employer must pay you directly for the completion of the form).

The WSIB encourages communication of functional abilities information between the workplace parties and the health care practitioner, because the Functional Abilities Form can help achieve a positive return to work outcome. The form allows your patient to consent to the release of functional information.
When you have completed the Functional Abilities Form, please provide pages 2 and 3 to your patient and/or their employer. This report should not include any diagnostic or confidential information, only functional abilities information. For more on how to complete the Functional Abilities Form, please refer to the Guide to Completing the FAF (PDF).
