Do Ontario Employers Have to Report ‘Near Miss’ Accidents to WSIB?

1 Jul 2026 5 min read No comments Workers’ Compensation (WSIB) Ontario
⚠️

In Ontario, employers do not have to report a “near miss” to the Workplace Safety and Insurance Board (WSIB) if no one was physically hurt and no medical care was required. However, under the Occupational Health and Safety Act, certain severe near misses (like scaffolding collapses or explosions) must be reported to the Ministry of Labour, and all near misses should be documented internally to prevent future tragedies.

Every day in busy Ontario workplaces, from construction sites in Toronto to massive distribution warehouses in Mississauga, workers experience terrifying “close calls.” A heavy pallet drops just inches from a forklift driver, or a worker slips on a wet floor but manages to catch their balance before tumbling down the stairs. These incidents are commonly known as “near misses.” Because the situation looked incredibly dangerous, employers often panic, wondering if they are legally obligated to contact the government to report the event.

The confusion usually stems from mixing up the rules of two different provincial bodies: the WSIB and the Ministry of Labour, Immigration, Training and Skills Development (MOL). 🔍 The WSIB is primarily an insurance board that compensates injured workers, whereas the MOL enforces safety laws to prevent accidents. Understanding exactly who to call, and when, is critical for business owners. Failing to report an actual injury can result in massive fines, while over-reporting harmless near misses simply creates unnecessary administrative chaos. Many employers choose to consult an Ontario employment lawyer or health and safety professional to build proper reporting protocols.

Step-by-Step Process for Handling a Near Miss in Ontario

When an incident occurs that could have resulted in a serious injury but did not, the employer must carefully evaluate the situation. Here is the step-by-step process to ensure full compliance with Ontario law.

Step 1: Check for Any Physical Injuries or First Aid

Your absolute first step is to confirm that the worker is completely unharmed. Sometimes a worker claims they are “fine” after a near miss, but later that evening, they go to the emergency room for back pain caused by twisting away from a falling object. If the worker requires any medical care from a health professional (like a doctor or chiropractor), or if they require time off work, it is no longer a near miss. It is now a workplace injury, and you must file a WSIB Form 7.

Step 2: Determine if Only Minor First Aid was Needed

If the worker simply needed a bandage from the site’s first aid kit and immediately returned to their regular duties, WSIB reporting is generally not required. 💙 The WSIB does not need to know about minor scratches or bruises that do not result in lost time or professional healthcare costs. However, you must legally record this first aid treatment in your company’s internal First Aid Log.

Step 3: Assess Ministry of Labour (MOL) Reporting Requirements

Even if no one was hurt, certain catastrophic near misses must be reported to the Ministry of Labour. Under the Occupational Health and Safety Act (OHSA), if your workplace experiences a structural failure (like a roof collapse), an explosion, or a major chemical spill, you generally must notify the MOL and your Joint Health and Safety Committee (JHSC) immediately. This allows inspectors to ensure the building is safe before work resumes.

Step 4: Conduct an Internal Incident Investigation

Just because you do not have to call the WSIB does not mean you should ignore the near miss. 📋 A near miss is a massive warning sign. Management and the JHSC should investigate exactly why the heavy pallet fell or why the floor was left wet. Document the findings in an internal incident report and implement corrective actions, such as buying better safety harnesses or training staff on proper load securing.

Step 5: Train Staff on Reporting Distinctions

Finally, ensure your supervisors understand the difference between WSIB and MOL reporting. When an actual injury occurs, they must act fast, as the WSIB mandates that the Form 7 must be received by the Board within three business days of the employer learning of the injury. Delaying an actual injury report because management thought it was just a “near miss” can lead to strict late-filing penalties.

How Much Does it Cost in Ontario?

  • WSIB Form 7 Filing Fee: $0 CAD. There is no charge to report an actual injury.
  • WSIB Late Reporting Fine: If you mistake an injury for a near miss and fail to report it within the required three-business-day window, the WSIB levies a $250 CAD late penalty, which automatically increases to $1,000 CAD if the report is delayed by more than 30 calendar days from the date the reporting obligation arose, regardless of prior history.
  • Ministry of Labour Fines: Failing to report a structural collapse or explosion to the MOL can result in corporate fines reaching up to $2,000,000 CAD under the OHSA.
  • Health and Safety Audits: Hiring an external consultant to review your near-miss logs typically costs between $1,500 and $5,000 CAD.
Internal First Aid Log Entry$0 CAD (Administrative duty)
WSIB Late Reporting Penalty$250 CAD ($1,000 CAD if delayed over 30 days)
OHSA Corporate Fines (Max)Up to $2,000,000 CAD

How Long Does the Process Take?

Proper incident management relies on immediate action. ⏱️ If an event qualifies as a reportable incident to the Ministry of Labour (like a major scaffold collapse), you must notify them immediately by telephone. If an injury actually occurs and triggers WSIB involvement, you have exactly three business days after learning of the injury to ensure the Form 7 is received by WSIB. For internal near-miss investigations, health and safety best practices suggest completing the review and corrective actions within 7 to 14 days.

Frequently Asked Questions (FAQ)

What if the worker goes to the doctor for a near miss just to be safe?

If the worker seeks assessment from a doctor or hospital, even as a precaution after a near miss, this generally triggers WSIB reporting. The doctor will likely submit a Form 8, meaning the employer must submit a Form 7 to avoid a mismatch in the WSIB system.

Do I need a lawyer if the Ministry of Labour investigates a near miss?

Yes, it is highly recommended. If the MOL arrives to investigate an explosion or equipment failure where no one was hurt, they can still issue stop-work orders or lay OHSA charges against the company for unsafe conditions. Having a local Ontario law firm on your side is critical.

Does psychological shock from a near miss count as an injury?

It can. If a worker is nearly crushed and suffers a severe, diagnosed psychological injury (such as PTSD) that requires medical treatment or time off work, it is no longer just a near miss. It is a reportable workplace mental stress injury under WSIB rules.

Should we keep near miss records forever?

While the law varies on retention, best practices in Ontario suggest keeping internal health and safety logs, including near misses, for at least three to five years to demonstrate a strong culture of safety to any visiting MOL inspectors.
