The WSIB Form 6, or Worker’s Report of Injury/Disease, helps workers in Ontario report an injury, illness, or exposure incident in the workplace. It generally covers what happened, when symptoms started, whether the employer was notified, any witnesses, and the care or treatment received.
With Heidi, you can easily:
The WSIB Form 6, officially titled the Worker’s Report of Injury/Disease, is the document an injured worker in Ontario submits to the Workplace Safety and Insurance Board to formally initiate a claim. Filing this report allows the worker to recount the injury narrative and establish the mechanism of the incident. It also authorizes you to share necessary functional information with the board.
Your team supports the worker’s compensation claim by diagnosing and documenting the injury, submitting the Form 8 report, and setting the patient’s functional
limitations. The worker provides consent to share this medical information by
signing the Form 6.
Complete, clinically grounded documentation lets the WSIB reach an initial eligibility decision without delay; a straightforward claim can be allowed and paid quickly. Vague or inconsistent documentation across the Functional Abilities Form, Form 6, and Form 8 often results in benefit delays. Deadlines sit around the claim itself: a worker has six months to file, and an employer has three business days to report.
WSIB Form 6 is the worker's report: the account an injured worker files to open the claim and consent to the release of their medical information. For the treating clinician it's the trigger instead of a form you complete. Once the worker files it, the claim exists, and your Form 8 and Functional Abilities Form have something to attach to.
Timing matters from there. Shorter delays between injury, reporting and treatment are linked to shorter overall work disability, so fast, accurate documentation is central to recovery.
For the clinician, WSIB Form 6 does three things:
Form 6 captures the worker's primary narrative of the incident, serving as the foundation WSIB uses to evaluate the claim alongside your Form 8 and the employer's Form 7. Discrepancies between this account and your clinical findings lead to claim delays. Aligning your documentation with the worker's report reduces the risk of delays and keeps the focus on treatment.
An injured worker files Form 6 to apply for benefits. A claim also opens when the employer submits Form 7 or the clinician submits Form 8, and treatment for most workplace injuries begins before the WSIB reaches a formal decision. Early, pre-approved care under a program of care supports the worker’s recovery.
Once the claim is accepted, the WSIB pays for approved treatment tied to it, such as physiotherapy and a program of care. Accurate documentation shortens the gap between assessment and treatment access. It also keeps return-to-work planning moving.
The WSIB opens a claim file and issues a claim number when any of the three reports reaches it: the worker's Form 6, the employer's Form 7 or your Form 8. In practice the employer's Form 7 often registers the claim first, and the WSIB then asks the worker to file Form 6. That claim number is what you need to bill for workplace injury care.
Once issued, the claim number ties every treatment and billing detail to one injury file, so your team spends less time chasing missing information and more time on the recovery of the worker.
his number keeps the injury, treatment, and billing details tied to a single file, so your team spends less time chasing missing information and more time on assessment, recovery, and return-to-work planning.
A worker claims WSIB benefits by signing Form 6, and it is one of three reports (Form 6, Form 7 or Form 8) that can open a claim file. Without a signed Form 6, the WSIB generally pays no more than two weeks of benefits.
Clinicians and WSIB reviewers read Form 6 against later medical evidence to check whether the injury account matches the clinical findings, which feeds the decision on the worker's entitlement to benefits.
The injured or ill worker completes WSIB Form 6, not the employer. If the worker is under 16, a parent or guardian must authorize the release of functional abilities information, but the worker still fills out the injury report.
You do not complete any part of Form 6: it is the worker's own report. The employer files the separate Employer's Report (Form 7), and your reporting is the Health Professional's Report (Form 8) and, where relevant, the Functional Abilities Form (FAF). If a patient asks you to fill in parts of their Form 6, point them to the WSIB portal to complete it themselves.
WSIB Form 6 records how a work-related injury or illness happened and when, along with the resulting symptoms and any limits on the worker’s duties.
Its other purposes are:
While the worker completes Form 6 to give what the injury entails, the employer completes Form 7 to report the incident and add the worker’s job details and the employer’s view of what happened. Read together, they give clinicians a clearer picture for assessing work-relatedness, documenting functional limitations, and planning safe return-to-work recommendations.
Completing this form can feel overwhelming when clinical details and documentation requirements compete for your attention. When it comes to documentation, the same exhaustion is experienced by Four Wings Psychology. Dr. Bellefontaine, Psychologist and Clinic Director, experienced cognitive overload from tracking clinical details and other documentation-related challenges.
Upon adopting Heidi, the practice reduced mental fatigue and cut the time spent on administrative work. Routine tasks like data entry or form-filling becomes something you can reliably designate to Heidi. That’s why automatically filling out the WSIB Form 6 makes the process clearer; the right details are logged accurately from the start.
Clear documentation prevents rework on WSIB claims. Document the worker's injury story, clinical context and its impact on work.
The best practices for ensuring clear documentation include these steps:
The WSIB's guide for Form 6 walks the worker through each section in order. Completing it in order builds a clear, chronological narrative that prevents inconsistencies and aligns the worker’s account with the clinical reasoning used to assess causation and treatment appropriateness.
Identify the source of injury for the employee and what task it affects. Express the result as a measurable restriction or accommodation need. This scope includes weight limit, duration limit, frequency limit, posture limit, or environmental limit.
For example, a patient with distal finger pain might find typing difficult. Frame the functional limitation clearly: typing is limited to 20% of the workday; avoid fine object manipulation.
Documenting occupational causation links the worker’s clinical presentation to a workplace exposure or incident. Do this using a clear exposure history, timing, and a plausible mechanistic or dose-response relationship.
Note timing and alternative explanations, as WSIB decision-making depends on evidence that the worker's condition is caused or significantly contributed to by work, not merely associated with it.
Once the worker is ready to begin return-to-work planning, you complete the Functional Abilities Form (FAF). The task limitations on Form 8 set the clinical baseline the FAF builds from. Both documents should be internally consistent.
Only share what is strictly necessary. Diagnosis, treatment, medication, medical history, and patient visits should not appear in employer-facing documents.
For example:
The worker is restricted from lifting above 5 kg, cannot climb ladders, and requires a gradual return to full duties over four weeks.
This is a clinical diagnosis that cannot be shared:The worker has a lumbar disc herniation at L4-L5 with right-sided radiculopathy secondary to accelerated degenerative disc disease.
When the worker signs Section G of Form 6, they consent to the clinician sharing functional abilities information via the FAF with the employer. Without a signed Form 6, the clinician cannot share FAF information directly with the employer.
Form 8 is a separate pathway submitted to WSIB under Section 37 of the WSIA without requiring worker consent. Both forms are independent.
Bill the professional assessment to the Ontario Health Insurance Plan (OHIP) with WSIB as the insurer. On the question of “How do I submit WSIB Form 6?”, submit all forms to the WSIB portal within six months of the service date to avoid fee reductions.
Billing rules are strict and not appealable once late penalties are applied.
