What Is the WSIB Functional Abilities Form (FAF)?

The WSIB Functional Abilities Form (FAF) is an official Ontario document that helps injured workers return to work safely. Officially known as form 2647A, it is completed by a treating health professional. It outlines physical abilities and limitations to help employers and workers find suitable job duties during recovery.

A key tool for return-to-work plans

The Workplace Safety and Insurance Board designed the WSIB FAF to help start return-to-work discussions. This official document is known as form 2647A. It serves as a communication tool to show what an injured worker can physically do.

The form gives employers and injured workers a common frame of reference to find suitable jobs. It does not share a private medical diagnosis, but focuses purely on functional abilities. This ensures your medical privacy remains protected while you recover.

The focus on functional abilities is what makes this form so useful. Instead of sharing a private medical diagnosis, the document lists what you are physically able to do. This includes how much you can lift, push, pull, or carry. It also lists details on how long you can sit, stand, or walk during a shift.

Who can ask for a WSIB FAF

The claims process can feel stressful, but getting this form completed is a routine step. Either the injured worker or the employer can request a WSIB FAF. Usually, an employer asks for the form to find out what duties are safe for you. This ensures the business is ready to make the right changes as you recover.

Who completes the official form

A licensed health professional who is treating you must complete the form. This can be a family doctor, a specialist, or a treating physiotherapist. They outline your physical limits, such as how much weight you can lift or how long you can stand. You can read more about how this step fits into filing a WSIB claim in Ontario.

Your doctor or physiotherapist completes the FAF at your request or at the request of your employer. This is different from the Form 8, which is filled out during your first medical visit. Under Ontario law, both workers and employers must work together to ensure an early and safe return to work. The FAF is updated as you heal to track your progress and change your duties.

Who Completes the FAF and How Does It Protect Your Privacy?

Your treating healthcare professional completes the WSIB FAF at your or your employer's request. To protect your privacy, the form focuses solely on your physical abilities and limits for work. It does not share your private medical diagnosis or private health history with your employer.

Healthcare professionals who fill out the form

Three parties are part of this return-to-work process. These are you (the injured worker), your employer, and your treating health professional. Either you or your employer can ask to have this form filled out. But only your treating health professional has the right to fill it out.

Under WSIB rules, this includes your doctor, your physiotherapist, or another licensed healthcare provider who is caring for you. Your provider will assess what you can do safely and write down these details. This is a key step after filing a WSIB claim in Ontario so that you can return to work without getting hurt again.

Required worker consent for the FAF

You must give your consent before any of your functional details are shared. You must agree to release these details to both the WSIB and your employer. This consent is key to keep your claim moving forward. If you refuse to share these details, it can cause delays or issues if your WSIB claim is denied. According to the Office of the Worker Adviser, giving consent allows your workplace parties to plan a safe return.

Functional limitations versus medical diagnosis

It is key to know that functional abilities refer to what you are physically able to do, not your medical diagnosis. According to the Office of the Worker Adviser, this rule keeps your medical details private. The form shows if you can lift weights, stand for long hours, or bend down. Your medical condition, such as a specific illness name, remains private. Your employer does not need to know your diagnosis to help you return to work.

Some employers might use their own custom forms instead of the standard WSIB FAF. Under WSIB rules, employers must pay your health professional directly to complete these custom forms. More than that, these forms must follow strict privacy rules. They must not ask for your diagnosis or private medical details of any kind. They must only ask about your physical abilities, just like the official WSIB Functional Abilities Form. If an employer's form asks for private health details, your doctor should only give functional details.

Unsure whether your privacy is being protected? You can find a WSIB lawyer or paralegal who will review your forms and protect your rights through every step of the process.

How the WSIB FAF Supports Your Return to Work in Ontario

The WSIB FAF supports your return to work in Ontario by outlining what physical tasks you can safely do. Under Ontario law, you and your employer must cooperate to find suitable, productive duties. This form ensures you only resume work when you are functionally able, helping protect your health and restore your earnings.

The duty to work together

When you suffer an injury at work, you must take active steps to heal and return. Under the Workplace Safety and Insurance Act, both you and your employer must work together. This legal process is known as early and safe return to work. You must stay in touch with your employer to find tasks that fit your health limits.

This shared effort starts early in your claim process. If you need help with filing a WSIB claim in Ontario, knowing your rights is key. You and your employer must talk often to plan your path. Together, you will look for ways to adjust your daily tasks so you can work safely.

1. Your doctor fills out the WSIB FAF to list your safe physical tasks.
2. You share the form with your employer when you are ready for some work.
3. Your employer uses your limits to find suitable duties for you.
4. You agree on assignments that are safe, available, and productive.

Finding suitable and productive duties

Your employer must try to give you suitable work as you heal. Suitable work means duties that are safe, available, and productive. The job must fit your physical limits and match what you can do. It should also help you do useful tasks that support the business.

The main goal is to restore your pre-injury earnings when possible. If you cannot do your old job, your employer may change your tasks or hours. This helps you earn a paycheck while you recover. It also ensures the business continues to run smoothly with your help.

The right timing for the form

Timing is critical when you use the WSIB FAF. Your doctor should only fill out the FAF when you are functionally able to return to some work. The form is not meant for the days right after a major injury when you cannot do any tasks. It is designed for when your healing has progressed enough to let you do light duties.

This approach prevents you from returning to work too soon. It gives your body the time it needs to heal from a work injury. At the same time, it keeps you connected to your job. When the time is right, the form serves as a clear guide to help you resume your work safely.

Common Mistakes Workers Make With the WSIB FAF

Your recovery can be hard, and making errors on your WSIB FAF can delay your benefits and return to work. Common mistakes include refusing consent, confusing this form with other board documents, and letting employers ask for private details. Avoid these missteps to keep your claim on track.

Should you refuse to sign the consent box?

You might worry about your privacy and ask: Should I refuse to share this form? While privacy is key, you must consent to the release of your functional details to both the WSIB and your employer. Withholding this consent can stall your return to work. It slows down the process of finding safe duties while you heal.

Another risk is not showing your limits clearly to your healthcare provider. You should ask yourself: Did I tell my doctor about all my pain and physical limits? If your health provider does not know what you can and cannot do, they cannot write an accurate form. This makes it hard for your employer to give you suitable tasks that will not hurt you more.

How does the FAF differ from the Form 8?

Workers often mix up these two forms and ask: Is this the same form my doctor filled out on my first visit? The answer is no. Your doctor or chiropractor uses the Form 8 to report the injury when you first get hurt. In contrast, you use the document to update the board, which has strict WSIB FAF requirements for your return-to-work plan.

Form 8.	WSIB FAF.
Reports your new workplace injury to the board.	Updates your physical abilities during recovery.
Completed by your doctor near your first visit.	Completed later, when you can return to some work.
Gives the initial details of the injury.	Focuses only on your functional limits.
Does not plan your return to work.	Helps find suitable duties for safe return.

You do not need to fill out a Form 8 again after your first doctor visit. Instead, you or your employer can request a WSIB FAF at any time during your recovery. This form gives the board and your employer fresh information so they can adjust your duties. Knowing the importance of the Functional Abilities Form is vital if your employer doubts your physical limits.

Can your employer make you sign their own forms?

You might get a custom form from your employer. You should ask: Do I have to use this instead of the official WSIB FAF? Under board rules, employers can use their own forms if they are tailored to their workplace. But the employer must pay your health professional directly to complete it. You should not have to pay for their custom paperwork.

Most of all, these custom forms must protect your privacy. You should ask your doctor: Does this custom form ask for my medical diagnosis? Employers' forms should not ask for diagnostic or private health details. They must only ask for your functional abilities. This means what you are able to do at work. If a custom form asks for private medical details, your doctor should only write about your limits.
