Employer Did Not Report Injury to WSIB: What to Do

An unreported workplace injury can delay the WSIB benefits you need. Your employer's silence does not end your claim, but you must act quickly to protect your rights and preserve key evidence.

Request help from a verified WSIB lawyer or paralegal through Claimit.

If your employer did not report injury to WSIB, contact WSIB yourself promptly. Describe the workplace event, injury, care, and time lost, then ask how to submit your worker report. Preserve medical notes, messages, schedules, photos, witness details, and proof that you notified your employer.

You may be unsure whether to call your employer again, contact WSIB first, or gather proof before doing either. The next section, Employer did not report injury to WSIB: immediate actions, puts those choices in a practical, clear order today. Here's how.

Employer did not report injury to WSIB: immediate actions

If your employer did not report an injury to WSIB, act now. You do not need to wait for your employer before seeking care or contacting WSIB.

Focus first on your health, then create a clear record of what happened. The steps below can help protect your claim and reduce gaps in the evidence.

Your immediate action checklist

Get medical care. Tell the health care provider that the injury happened at work. Explain when it happened, how it happened, and which tasks caused or worsened your symptoms.
Notify your employer in writing. Send an email or letter to a manager, supervisor, or human resources contact. State the injury date, location, symptoms, witnesses, and the work you were doing.
Document the event. Write a detailed timeline while the facts are fresh. Save photos, witness names, shift records, texts, emails, and any incident report you completed.
Contact WSIB directly. Use the WSIB's injury reporting information to learn how to report the injury yourself. Tell WSIB that your employer has not filed its report.
Preserve every record. Keep copies of medical notes, prescriptions, forms, pay stubs, work schedules, and messages. Store them outside your work email or workplace device.

Ontario worker following the steps to file a WSIB claim — Organizing each reporting step helps protect a WSIB claim when an employer has not filed.

For more detail on starting the process, follow this step-by-step guide to filing a WSIB claim in Ontario.

What to include in your written notice

Your written notice should be brief and factual. Include the date and time, the worksite, the task involved, your symptoms, and the names of witnesses.

Ask your employer to confirm receipt and explain whether it will report the injury. Ontario's workplace injury reporting guidance explains the employer's reporting role and what workers can do.

Do not argue about fault in the notice. A clear timeline and specific details are more useful than guesses about why the injury happened.

When the employer disputes the injury

An employer may say the injury was not work related or did not require reporting. Keep documenting your symptoms and care, and give WSIB your account directly.

Record each contact with your employer and WSIB. Note the date, the person's name, what you shared, and any next step they gave you.

If you need help with a denied or disputed claim, you can review WSIB lawyers and paralegals who handle workplace injury matters. Bring your timeline and saved records when asking for help.

When must an Ontario employer report an injury?

An Ontario employer generally must report when a workplace injury causes health care beyond first aid, lost time, reduced pay, or certain modified duties. Once the employer learns of a reportable accident, it generally has three days to notify WSIB. A missing report does not prevent the worker from reporting.

Ontario employers generally must report a work injury when it creates a possible WSIB benefit entitlement. The duty comes from Ontario's Workplace Safety and Insurance Act, not from an employer's view of who caused the incident.

Under the Act, an employer must notify the WSIB within three days after learning of an accident that triggers reporting. This timing can matter when an employer did not report injury to WSIB and the worker is trying to protect a claim.

Main reporting triggers

An injury is usually reportable once the worker needs health care beyond first aid, even if the worker misses no time. The WSIB's reporting guidance also identifies lost time, lower wages, and certain modified work arrangements as reporting triggers.

First aid alone does not usually create a reporting duty. Yet an employer must report if the injury later needs professional care or starts affecting the worker's duties, hours, or pay.

Common WSIB employer reporting triggers
Workplace injury situation	General reporting result	Reason
First aid only	Usually no report	No health care beyond first aid
Health care beyond first aid	Report	Medical care is a reporting trigger
Missed regular work	Report	The injury caused lost time
Regular work at reduced wages	Report	The worker earns less after the injury
Modified work at reduced wages	Report	The change affects both duties and pay
Modified work at regular pay	Report after more than seven calendar days	A short, fully paid change is treated differently

Modified work and reduced wages

Modified work can trigger a report right away when the worker earns less than regular pay. If regular pay continues, reporting is generally required once the modified work lasts more than seven calendar days.

The employer reports on the eighth calendar day when that threshold is crossed. The key issue is the real change in the worker's tasks, hours, or earnings, not the label placed on the arrangement.

When the employer does not report

A late or missing employer report does not, by itself, erase the worker's ability to make a claim. The worker can contact the WSIB and explain the injury, care received, missed time, modified duties, and wage changes.

Keep copies of medical notes, schedules, pay records, and messages sent to a supervisor. Workers who want help reviewing a missing report can find a WSIB lawyer or find a WSIB paralegal through Claimit.

How can you report the workplace injury yourself?

You can report the workplace injury directly to WSIB online, by phone, or through the Worker's Report of Injury/Disease, known as Form 6. Give a factual timeline, identify affected body areas, explain medical care and work impacts, request a claim number, and keep copies of every submission.

If your employer did not report the injury to WSIB, you can start the claim yourself. Do not wait for your employer to act. Reporting early helps WSIB gather facts while records and details are easier to find.

Ways to report your injury

Workers can report an injury or illness to WSIB online, by phone, or with Form 6. This form is called the Worker's Report of Injury/Disease. It asks what happened, when it happened, where you received care, and how the injury affects your work.

Ontario rules require employers to report certain work-related injuries and illnesses. The Ontario government's workplace injury reporting guide explains when an employer must notify WSIB. Your right to report does not depend on whether your employer agrees with your account.

Steps for making your own report

Use these steps if your employer did not report the injury to WSIB. They also apply if you are unsure whether a report was filed.

Tell your employer about the injury in writing. State the date, time, place, task, symptoms, and names of any witnesses.
Get medical care when needed. Tell the health care provider that the injury happened at work. Describe your duties and symptoms clearly.
Gather key records before you report. Keep photos, witness details, work schedules, medical notes, employer messages, and lost-time records.
Report the injury directly to WSIB. Use the online worker reporting route, call WSIB, or complete Form 6 as instructed.
Ask WSIB for your claim number. Save it with copies of every form, letter, and document you submit.
Check the details in your claim file. Contact WSIB if the injury date, job duties, symptoms, or time away are wrong.

You do not need polished legal terms to explain what happened. A simple, detailed timeline can make your report easier to follow. Separate what you saw or felt from what another person told you.

What to include in your report

Give a clear account in the order events occurred. Explain the work task, the injury or exposure, and when symptoms began. State when you told your employer. Include all affected body areas, even if one area seems less painful at first.

Stick to facts and avoid guessing. If you do not know an exact time or detail, say so. Keep a dated note of each call and submission. Record the name of each person you spoke with.

A worker report starts the claim review, but WSIB may still seek information from your employer and care providers. You may also be asked for more records or a clearer account. Respond by the stated deadline, and keep a copy of what you send.

If you need help preparing your account, use the Claimit intake form to connect with a WSIB lawyer or paralegal who can review your situation.

What evidence should you preserve?

Preserve records that show the event, notice to your employer, medical care, and impact on your work. Save messages, incident forms, photos, witness details, medical notes, schedules, pay records, and modified-duty information outside employer-controlled systems. Build a dated timeline and keep original files whenever possible.

If your employer did not report injury to WSIB, preserve records before details are lost or access changes. Evidence should show what happened, when it happened, who knew, and how the injury affected your work.

Notice and incident records

Keep a copy of every written notice you gave your employer. Save emails, texts, chat messages, incident forms, and any reply from a supervisor. If you reported the injury by phone or in person, write a dated note describing the talk.

Record the incident details while your memory is fresh. Note the date, time, location, task, equipment, and events that led to the injury. List each witness and their contact details, but do not pressure anyone to provide a statement.

Save photos of the location, equipment, visible injury, and any safety issue.
Keep copies outside your work email or employer-owned device.
Preserve original files when possible, including full message threads and photo details.

Medical and work records

Keep medical notes, visit summaries, test results, prescriptions, referrals, and treatment plans related to the injury. Tell each care provider that the injury happened at work. Their records can help connect your symptoms, treatment, and limits to the incident.

Save work schedules, time sheets, pay stubs, and records of missed shifts or changed duties. These documents can show your normal hours and what changed after the injury.

Ontario's guidance on reporting workplace incidents and illnesses explains key reporting duties. Keep records of any steps you take after reading official guidance.

A clear timeline

Create one timeline that brings the records together. Start with the incident, then add each report, medical visit, missed shift, work change, and employer response. For every entry, note the date, people involved, and the record that supports it.

Do not edit old messages or fill gaps with guesses. Instead, label uncertain details as estimates and explain why. A clear, honest record is easier for a representative to review than a folder of files without context.

You can use the Claimit intake form to explain what happened and request help from a WSIB representative.

You can also review WSIB lawyers and paralegals who may assess the records and discuss possible next steps.

Which WSIB reporting deadlines matter?

The employer generally has three days after learning of a reportable accident to notify WSIB, while a worker generally has six months from the accident date to claim benefits. These are separate timelines. Report promptly yourself, preserve proof of submission, and confirm the deadline that applies to your circumstances.

Two timelines matter after a workplace injury: the employer's reporting deadline and the worker's claim deadline. They are separate duties. If your employer did not report injury to WSIB, its missed deadline does not mean you should wait to protect your claim.

The employer's three-business-day timeline

An employer must generally report a work-related injury or illness within three business days after learning it must be reported. This timeline applies when the employer learns that the incident caused health care, lost work time, or another reportable result.

The governing rules appear in Ontario's Workplace Safety and Insurance Act, 1997. The Act requires notice within three days after the employer learns of the accident. It also sets out the worker's separate claim timeline.

A late or missing employer report can slow the start of a claim. Keep your own dated notes, medical records, emails, and messages about the injury. These records can help show when the incident happened and when your employer learned about it.

The worker's six-month claim timeline

Workers generally have six months from the accident date to file a WSIB claim. For an occupational disease, the timing can depend on when the worker learned the disease was work-related. Do not assume the employer's report starts or protects your claim.

File promptly, even if details are still being gathered. Waiting can make it harder to collect records, confirm witnesses, and explain gaps in medical care. If the deadline may be close, contact WSIB and ask what must be submitted now.

Steps to take when dates are unclear

Start by making a simple timeline. Include the injury date, when you told your employer, your first medical visit, missed shifts, and each contact with WSIB. Save copies instead of relying on workplace files that you may not control later.

Ask WSIB whether a claim and employer report are already on file.
Confirm the deadline that applies to your facts and note who gave the answer.
Submit your worker report promptly and keep proof of delivery.
Get advice if the six-month period has passed or the injury developed over time.

Deadline rules can turn on the type of injury and the facts of the case. Confirm current requirements directly with WSIB. If WSIB has issued a decision, learn about the WSIB objection form deadline. You can also review WSIB lawyers and paralegals if you need help with a missing report or a late claim.

What happens after you contact WSIB?

After you report, WSIB may gather information from you, your employer, and health care providers before deciding the claim. It may ask about the event, symptoms, treatment, notice, and work changes. Respond by stated deadlines, correct inaccurate facts promptly, and keep your claim number and copies of all communications.

After you contact WSIB, the claim process moves from reporting the injury to gathering and checking information. WSIB may ask you, your employer, and your health care provider for details about the event and your condition. Keep each request, response, and record together so you can track what has been shared.

This review can cover how the injury happened, when symptoms began, and how the injury affects your work. WSIB may also compare accounts or seek missing records before making a decision. A prompt, clear response can help prevent avoidable gaps.

Information WSIB may review

WSIB usually needs enough information to connect the injury or illness with your work. Your account matters, but it is often reviewed with medical records and workplace details. Give clear dates when you can, and explain when you are unsure of an exact date.

How, where, and when the injury happened
When you told your employer or supervisor
Medical visits, treatment, and work limits
Witness names and any written workplace records

Send records that answer the question being asked. Keep copies of anything you provide, including online forms and email messages. If WSIB asks for something you cannot get, explain why and ask what other proof may help.

When the employer did not file a report

Ontario's Workplace Safety and Insurance Act sets out an employer's reporting duty. A missing report does not automatically decide whether your claim is allowed. WSIB can still look at your account, medical notes, witness details, and other available evidence.

The phrase employer did not report injury to WSIB describes a problem, not the final result. Tell WSIB when and how you notified the employer. Share any texts, emails, incident forms, or witness details that support your account.

Pressure, denial, and appeal help

An employer may question your account, discourage reporting, or ask you to use sick time instead. Do not argue about the claim at work. Write down what was said, when it happened, and who was present.

Save texts, emails, schedules, incident reports, and medical notes in a secure place outside your work account. Tell WSIB about any pressure that affects your ability to provide information. Keep your account factual and consistent; avoid guessing when you do not know an answer.

If WSIB denies the claim, read the decision letter closely and note the stated reasons. Review these steps for getting help after a WSIB claim denial. A WSIB lawyer or paralegal can help you understand the denial and your options. Advice may help when accounts conflict, evidence is missing, or the claim involves lasting work limits.

Injured Ontario worker reviewing steps after a denied WSIB claim — A careful review of the decision and supporting records can clarify the next step after a denial.

Appeal deadlines can matter. Request help with a WSIB appeal and share the decision letter so a representative can review which records may address WSIB's reasons.

When should you speak with a WSIB representative?

Speak with a WSIB lawyer or paralegal when the employer disputes the injury, evidence is missing, a deadline is near, or WSIB denies or delays the claim. A representative can review the record, explain available options, and help identify the most important documents or response steps.

It may help to get advice as soon as a claim becomes hard to explain or prove. This is often true when your employer did not report injury to WSIB or disputes that the event happened at work. Early advice can help you see what records are missing and what steps remain open.

Warning signs that advice may help

Consider speaking with a WSIB lawyer or paralegal when your account and your employer's account do not match. Help may also be useful if witnesses are hard to reach, medical notes are missing, or someone pressures you to change your account.

Your employer denies that the injury happened at work.
You received a denial or a decision you do not understand.
A deadline is close, but you are unsure what to file.
Your injury developed over time or has more than one cause.
Your medical limits, return-to-work plan, or benefits are disputed.

Good records give a representative a clearer view of the dispute. Save medical notes, messages, schedules, names of witnesses, and a short timeline of events. Learn more about workplace injury rights under Ontario's WSIA before discussing the record with a representative.

When the claim is denied or delayed

A denial does not always end the matter. A representative can review the decision, explain the stated reasons, and help you assess the next step. This review matters when evidence was overlooked or the claim involves a complex injury.

Do not wait until the last moment if a decision lists a response date. A lawyer or paralegal needs time to read the file and understand your goals. You can compare WSIB lawyers and paralegals with experience in these types of disputes.

What Claimit can and cannot do

Claimit is a marketplace, not a law firm, and it does not give legal advice. It helps injured Ontario workers find WSIB lawyers and paralegals who can review their situation. The representative you choose can explain their services, fees, and possible next steps.

You do not need to know exactly what kind of help you need before you start. Share the key facts, the documents you have, and any deadline shown on a WSIB decision.

Frequently Asked Questions

Can I report a workplace injury myself if my employer refuses?

Yes. An injured Ontario worker can contact WSIB and file a worker's report even when the employer has not reported the injury. Record the incident, seek medical care if needed, and tell the provider it happened at work. Keep copies of forms, messages, schedules, and medical records. Do not wait for the employer before starting the claim process.

What evidence should I keep when my employer did not report my workplace injury?

Keep a dated account of the injury, witness names, photos, work schedules, and any incident reports. Save texts or emails showing when you notified the employer and how they responded. Ask your medical provider to record that the injury happened at work. The evidence should clearly show what happened, when symptoms began, and how the injury affected your work.

Can my employer punish me for reporting a workplace injury to WSIB?

Workers can submit a WSIB claim without their employer's permission. If an employer cuts hours, threatens dismissal, fires a worker, or pressures them not to report, document each event and save related messages. Seek prompt advice from a legal representative, union, or appropriate Ontario workplace body. The available response depends on the facts and the worker's employment situation.

What happens after I report the injury to WSIB myself?

WSIB may contact the worker, employer, and health care providers to gather information about the injury and its effect on work. Respond promptly, keep the claim number, and save every letter or decision. An employer's disagreement does not automatically decide the claim. If WSIB denies benefits or records incorrect facts, review the decision and seek help quickly because time limits may apply.

When should I get legal help for an unreported workplace injury?

Consider getting help when the employer disputes the injury, WSIB denies the claim, symptoms continue, or the case involves missed work. Help may also be useful if an employer pressures a worker not to report or if a deadline is unclear. A WSIB lawyer or paralegal can review the facts, explain available options, and assist with forms or an appeal.
