Penalties for Employers Who Fail to Report a Workplace Injury in Ontario

14 Jun 2026 6 min read No comments WSIB Claims & Workplace Injuries Ontario

Under the Workplace Safety and Insurance Act (WSIA), Ontario employers must report a workplace injury requiring healthcare or resulting in lost time within exactly 3 days. Failing to report, filing late, or engaging in claim suppression can result in corporate fines of up to $500,000 CAD and potential jail time for company directors.

Maintaining a safe workplace is the highest priority for businesses operating in Ontario, but accidents inevitably happen. When a worker is injured on the job in Toronto, Mississauga, Sudbury, or any other municipality, employers have immediate and incredibly strict legal obligations to report the incident to the Workplace Safety and Insurance Board (WSIB). Unfortunately, some employers make the grave mistake of delaying their report or actively trying to hide the injury to protect their premium rates.

Failing to report a workplace injury-or worse, engaging in active claim suppression-is considered a severe legal offence in Canada. 👮 The WSIB and the Ontario Ministry of Labour aggressively investigate and fiercely prosecute these violations. This guide outlines the proper reporting procedures, details the severe financial and legal penalties for non-compliance, and explains why retaining a law firm is critical if you are facing a WSIB prosecution or an Ontario Court of Justice summons.

Understanding What Constitutes Claim Suppression

Claim suppression occurs when an employer uses coercion, threats, or illegal financial incentives to prevent an injured worker from filing a WSIB claim. This illegal practice undermines the entire workers’ compensation system in Ontario. Examples of claim suppression include offering to pay the worker’s wages out-of-pocket if they stay home, threatening to terminate their employment if they report the injury, or forcefully driving the worker to a clinic and demanding they lie to the doctor about where the injury occurred.

The WSIB utilizes advanced data analytics, anonymous whistleblower tip lines, and routine audits to actively hunt for signs of claim suppression. 🔍 If your business is caught engaging in these practices, you will face not only standard administrative penalties but likely full criminal-style prosecution under the Provincial Offences Act.

Step-by-Step Process for Properly Reporting an Injury in Ontario

To completely avoid devastating fines and legal liabilities, Ontario employers must follow a rigid reporting procedure the moment a workplace accident occurs. Implementing these exact steps within your corporate HR policy is highly recommended.

Step 1: Provide Immediate First Aid and Transportation

Your first legal duty is to the physical health of the worker. 🏥 You must immediately provide appropriate first aid on-site. If the injury requires professional medical attention, the employer must arrange and completely pay for transportation to the nearest hospital or medical clinic. You cannot force the injured worker to drive themselves or pay for their own taxi.

Step 2: Investigate and Secure the Scene

If the injury is critical (e.g., amputation, severe bleeding, or a fatality), you must immediately secure the accident scene and notify the Ministry of Labour. 🚨 Do not disturb the machinery or equipment involved. Conduct a prompt internal investigation, take comprehensive photographs, and gather detailed written statements from any employees who witnessed the event.

Step 3: Determine if the Incident is Reportable to WSIB

Not every minor papercut needs to be reported. You must report the incident to the WSIB if the worker requires medical treatment beyond simple on-site first aid, loses time from work past the day of the accident, or requires modified duties at less than regular pay for more than seven calendar days. If in doubt, it is generally safer to report it.

Step 4: Complete and Submit WSIB Form 7

The core of your reporting obligation relies entirely on the WSIB Form 7 (Employer’s Report of Injury/Disease). 📤 You must accurately and truthfully complete this extensive form and ensure the WSIB formally receives it within exactly three (3) calendar days of you learning about the reportable incident. Provide a copy of the completed Form 7 directly to the injured worker as well.

Step 5: Cooperate Fully with WSIB Investigations

Once the claim is filed, you must cooperate continuously with the WSIB. If a WSIB investigator or an adjudicator requests payroll records, safety logs, or additional context regarding the mechanism of injury, provide the exact information promptly. Obstructing a WSIB investigation is a separate offence that carries its own heavy penalties.

How Much Are the Fines for Failing to Report?

The financial penalties for non-compliance are structured to be aggressively punitive to completely deter bad employer behaviour. Penalties are split between automatic administrative fines and massive legal prosecution fines handed down by a judge.

  • Initial Late Reporting Fine: Simply submitting Form 7 late triggers an automatic administrative penalty of $250 CAD.
  • Subsequent Late Reporting: Repeated late reporting offenses can result in fines up to $1,000 CAD per individual incident.
  • Conviction for Individuals/Directors: If an individual manager or company director is prosecuted and convicted of an offence under the WSIA (like claim suppression), they face fines up to $25,000 CAD and up to six (6) months in provincial jail.
  • Conviction for Corporations: A corporate entity successfully convicted of a WSIA offence faces catastrophic fines of up to $500,000 CAD per charge.

How Long Do You Have to Report?

The reporting timeline is incredibly strict. ⏱ In Ontario, an employer has exactly 3 calendar days (which includes weekends and statutory holidays) from the moment they learn that an injury requires health care or involves lost time to submit the completed Form 7 to the WSIB. Furthermore, if a worker faces a critical injury or fatality, the Ministry of Labour must be notified immediately by telephone.

Frequently Asked Questions (FAQ)

What if the worker explicitly asks me not to report the injury to WSIB?

You must report it anyway. Under Ontario law, an employer cannot contract out of the WSIA. Even if the worker begs you not to file Form 7 or promises not to sue, you have a non-negotiable legal obligation to report any qualifying injury immediately.

Do I have to report an injury if there is no lost time from work?

Yes, if the worker required professional healthcare treatment (like getting stitches at a clinic or visiting a chiropractor). Even if they return to their regular shift the very next day, the need for professional medical care automatically triggers the reporting requirement.

What should I do if I suspect the worker is faking the workplace injury?

You must still strictly submit Form 7 within the 3-day window. However, you should include a detailed letter outlining your operational doubts, attach any contradicting witness statements, and formally request that the WSIB investigate the validity of the claim.

Can I be sent to jail for not reporting a WSIB claim?

Yes, it is possible. While jail time is generally reserved for the most egregious, intentional cases of fraud or severe claim suppression, individual directors and officers can be sentenced to up to 6 months in jail under the WSIA.

Should I hire a lawyer if a WSIB investigator contacts my business?

Absolutely. If the WSIB Regulatory Services branch contacts you regarding potential offences or claim suppression, you are under formal investigation. Retaining an Ontario law firm immediately is critical to ensure you do not self-incriminate your business.
