Last updated: March 2026

An incident report is a formal written document that records the details of any workplace event that causes or could cause injury, illness, or property damage. Properly documenting incidents helps identify dangers in the work environment and avoid situations that could potentially endanger people.

Here is the reality most contractors learn the hard way: a 15-person framing crew in Calgary has a worker fall from scaffolding. No broken bones, but the worker hits his head and goes to the emergency room. The foreman thinks, "He's fine, walked it off." Three weeks later, Alberta OHS shows up asking for the incident report. There isn't one. Now the company is facing an investigation, potential fines, and a reputation hit with their GC. All because nobody documented what happened within the first 24 hours.

Most importantly, a well-written incident report can help ensure that your company is compliant with Canadian workplace safety regulations. Every company has unique guidelines when filing incident reports, but the structure and the essential elements are the same. Below, you will learn how to write an incident report that is thorough, accurate, and compliant, with a free template you can download and use right away.

⚡ Quick Answer: How to Write an Incident Report
  • What: A formal document recording who, what, when, where, and why for any workplace incident
  • When: Within 24 hours of the incident, while details are fresh
  • Key elements: Basic info (names, date, location), accuracy, objectivity, legal considerations, cause analysis, supervisor sign-off, and confidentiality
  • Reporting deadlines: Vary by province: immediate for fatalities/critical injuries in all jurisdictions; 72 hours (BC), 3 business days (Ontario), or ASAP (Alberta) for standard injury claims
  • Free template: Download our Incident Report & Investigation Kit to get started

What Types of Incidents Require a Report?

Eight types of workplace incidents that require a formal report: medical treatment injuries, fatalities, near misses, property damage, occupational illnesses, hazardous substance releases, structural failures, and fires and explosions

Not every scraped knee needs a formal report, but the threshold is lower than most people think. As a general rule, if something happened and anyone could have been hurt, document it. If you are unsure whether your current process covers the right incidents, book a free safety assessment and we will review your reporting procedures in 30 minutes. Canadian workplace safety regulations require reporting for:

  • Injuries requiring medical treatment beyond basic first aid
  • Fatalities and critical injuries (immediate reporting to your provincial regulator)
  • Near misses where no one was hurt but easily could have been (a dropped load, a tripped breaker, an unsecured ladder that shifted)
  • Property damage to equipment, vehicles, or structures
  • Occupational illnesses such as hearing loss, respiratory conditions, or repetitive strain injuries connected to the work
  • Hazardous substance releases including chemical spills, gas leaks, or uncontrolled dust exposure
  • Structural failures such as scaffold collapses, crane upsets, or excavation cave-ins
  • Fires and explosions whether or not anyone was injured

The distinction between an "incident" and an "accident" matters here. An incident is any unplanned event that disrupts normal work, while an accident specifically results in injury or damage. Smart safety programs report both. For a deeper look at this distinction and why it matters for your safety program, read our guide on incidents vs. accidents and why you should investigate both.

Near misses deserve special attention. They are free warnings. A near miss today is often the rehearsal for a serious injury tomorrow. If your crew reports near misses consistently, you can fix hazards before they hurt someone. We cover this in detail in our guide to near-miss incident reporting.

📹 Watch: How to Write an Incident Report — 7 Essential Elements

1. Basic Incident Information

7 essential elements of an incident report diagram: basic information, accuracy, objectivity, legal considerations, cause analysis, supervisor signature, and confidentiality

The incident report must be factual and complete. It should include:

  • The names and positions of the people involved
  • The names of any witnesses
  • The exact location and/or address of the incident
  • The exact time and date of the occurrence
  • A detailed and clear description of what exactly happened
  • A description of any injuries sustained
  • Any first aid or medical treatment provided at the scene
  • The environmental conditions at the time (weather, lighting, noise level)

No information can be left out. Start writing the report as soon as possible. The longer you wait, the more difficult it becomes to accurately document the details. It is best to complete the write-up when everyone's memory of the incident is still fresh, ideally within the same shift.

For a detailed, step-by-step walkthrough of exactly how to fill out each section of a report, see our step-by-step guide to writing an incident report.

With Safety Evolution's Incident Reporting & Investigation System, workers are guided through interview-style questions as they complete their event report. As they toggle on answers to questions such as "Were there any witnesses?", more in-depth questions are asked to ensure a full report. Incident reporters can capture date, time, location, witness statements, property damage, environmental damage, weather factors, work permits, scene changes, and more. They can link injuries to specific body parts and upload relevant photos and documents.

2. Accuracy

The document must be accurate and free of grammatical or spelling errors. Ideally, there should not be any corrections, especially if it is handwritten. If any corrections must be made, every deleted or added word may need to be initialed by the witnesses. The last thing you want is for the report to be open to interpretation. Read the report multiple times and look for any gaps that need to be filled in. Is there a missing part of the story? Could any piece of the story be further clarified? Remember to include not only the actual incident but the events that took place before and after as well.

One common mistake: writing "the worker was careless" instead of "the worker's foot slipped on a wet surface while carrying a 50 lb pipe section." The first is a judgment. The second is a fact that points to a fixable hazard (wet surface, load handling procedure). Accuracy means describing what happened in enough detail that someone who was not there can picture the sequence of events.

3. Objectivity

Avoid using emotional words and statements that describe feelings. The report must be factual and free of sarcasm, condescending statements, and judgmental remarks. The person in charge of the written reporting is expected to rely purely on facts, detecting and avoiding personal biases and opinions. To achieve this, the writer must not allow earlier or external information to influence the report.

Write what you observed, not what you assumed. Instead of "the worker was not paying attention," write "the worker was facing away from the approaching forklift at the time of contact." Let the facts speak. The investigation will determine root cause; the report's job is to capture what happened.

4. Incident Legal Considerations

Remember that incident reports are legal documents that may be utilized by investigators, regulators, and courts. The report should clearly state if the incident involves any of the following:

  • Physical injury
  • Assault
  • Property destruction
  • Work-related accidents
  • Theft or robbery
  • Aggressive behavior
  • Serious illness
  • Imminent death
  • Illegal and criminal acts
  • Disruptive situations

If you are not sure whether a report is necessary, consider the wisdom of "better safe than sorry." If the incident is extreme, it may be appropriate to immediately contact emergency services. Always check with your provincial workplace safety regulator (such as WorkSafeBC, Alberta OHS, or the Ontario Ministry of Labour) to ensure your company is fully compliant with reporting timelines and requirements.

For a complete breakdown of legal obligations around incident reports in Canada, including confidentiality rules, retention periods, and when reports can be used in court, see our legal guide to incident report confidentiality and retention.

5. Cause of Incident

If the exact cause of the incident remains undetermined after the initial investigation, it is acceptable to share hypotheses as long as they are clearly identified as such in the report. Include statements from witnesses, sketches, and photos whenever possible. If available, security footage should be referenced as well. For a deeper look at how to investigate causes effectively, see our guide on capturing the scene and finding root cause.

Most contractors think the cause analysis section is optional, something the safety department handles later. They are wrong. Even a preliminary cause note in the initial report ("worker slipped on ice that had formed overnight on an uncovered walkway") helps investigators and regulators understand the sequence of events. Root cause analysis may come later, but the first report should at least document the observable conditions that contributed to the incident.

6. Supervisor Signature

The completed report must be signed by the supervisor or manager in charge at the time of the incident. As the authorized signatory, they must read the report and ensure that it is clear, legible, and accurate, and that the company guidelines for incident reporting have been strictly followed.

The supervisor's signature is not just a formality. It confirms that the report was reviewed by someone with authority and that the documented facts were verified. In the event of a regulatory investigation or legal proceeding, a missing supervisor signature can raise questions about whether the report was properly reviewed. If the supervisor was not on site at the time of the incident, the next person in the chain of command should sign and note the reason for the substitution.

7. Confidentiality

Because reports almost always include sensitive and confidential information, such as an employee's health concerns, incident reporting must be done with the involved parties' privacy in mind. Only authorized personnel should be able to review the report details. Proper storage (whether physical or digital) is essential to maintaining confidentiality.

In Canada, personal health information in incident reports is protected under provincial privacy legislation (such as Alberta's Health Information Act and Ontario's Personal Health Information Protection Act). Sharing report details with unauthorized people, even within your own company, can create legal liability. Limit access to the supervisor, safety officer, HR, and any regulatory inspectors who request it. Digital incident reporting systems can enforce access controls automatically, which is one of their key advantages over paper-based processes.

For the full picture on how long you must keep incident reports, who can access them, and when they can be used as evidence, read our incident report confidentiality and retention guide for Canada.

Canadian Provincial Reporting Requirements

Canadian provincial incident reporting deadline comparison: British Columbia (WorkSafeBC, Form 7 within 72 hours), Alberta (OHS ASAP, WCB 72 hours), and Ontario (Ministry of Labour immediate, written report 48 hours, WSIB 3 business days)

Incident reporting deadlines and procedures vary by province. Getting this wrong can result in fines, penalties, and complications with your workers' compensation claims. Here is what you need to know for the three provinces where most of our clients operate:

British Columbia (WorkSafeBC)

  • Immediate notification to WorkSafeBC's Prevention Information Line for: worker fatalities, serious injuries (life-threatening or potentially causing permanent impairment), major structural failures or collapses, hazardous substance releases, and dangerous fires or explosions
  • Employer's Report of Injury (Form 7) must be submitted within 72 hours of becoming aware of a workplace injury or illness
  • Do not disturb the scene until a WorkSafeBC officer gives permission (with exceptions for attending to injured workers, preventing further harm, or protecting property)
  • Employer investigation required for all incidents that required immediate notification

For a complete walkthrough of BC's reporting requirements, forms, and timelines, see our WorkSafeBC incident report guide.

Alberta (Alberta OHS)

  • Call the OHS Contact Centre (1-866-415-8690) as soon as possible for: worker fatalities, hospital admissions (not including ER visits), uncontrolled explosions/fires/floods with potential for serious injury, crane/derrick/hoist collapses, and building or structural failures
  • Do not disturb the scene of any fatality, hospital admission, or serious incident until an OHS officer or police officer gives permission
  • Prime contractor reports (or employer if no prime contractor). The investigation must produce a written report covering the circumstances and preventive measures
  • WCB Alberta claim reporting: employers must report injuries requiring medical aid to WCB within 72 hours

Alberta updated its scene disturbance rules in 2025, tightening the requirements around what employers can and cannot do at an incident scene before an OHS officer arrives. For full details on Alberta's current requirements and templates, see our Alberta incident report template and guide.

Ontario (Ministry of Labour / WSIB)

  • Immediate notification to the Ministry of Labour, Immigration, Training and Skills Development (1-877-202-0008, 24/7) for all fatalities and critical injuries. A critical injury includes: fractures of a leg or arm, amputations, loss of consciousness, substantial blood loss, burns to a major portion of the body, or loss of sight in an eye
  • Written report within 48 hours to the Ministry of Labour, the joint health and safety committee, health and safety representative, and trade union
  • WSIB Form 7 must be submitted within 3 business days of learning about the injury if the worker requires health care, is absent from work, earns less than regular pay, or requires modified work
  • Do not disturb the scene until a Ministry inspector directs otherwise

For Ontario-specific forms, examples, and a walkthrough of both Ministry and WSIB reporting, see our Ontario workplace incident report guide.

If you operate in multiple provinces, the reporting requirements for each province apply to the work sites in that jurisdiction. A company headquartered in Alberta with a crew working in BC must follow WorkSafeBC rules for the BC site. When in doubt, talk to a safety consultant who understands multi-province operations.

How Long Should You Keep Incident Reports?

Incident report retention periods by Canadian jurisdiction: British Columbia 3 years, Ontario 3 years, Alberta 3 years (30-40 years for hazardous substances), Federal 10 years, with a best practice recommendation of 5 years minimum

Retention requirements vary by jurisdiction, but the short answer is: longer than you think.

  • British Columbia: Employers must keep incident investigation reports for a minimum of 3 years from the date of the incident (per the OHS Regulation)
  • Ontario: Accident, injury, illness, and death reports must be retained for at least 3 years
  • Alberta: Employers must keep copies of incident investigation reports and provide them to an OHS officer on request. Best practice is a minimum of 3 years, though records related to hazardous substance exposure should be kept for much longer (up to 30-40 years)
  • Federally regulated workplaces: Hazardous occurrence reports must be kept for 10 years

Best practice: keep all incident reports for a minimum of 5 years, and indefinitely for any incident involving a fatality, serious injury, or hazardous substance exposure. Digital storage makes this easy and costs almost nothing. For the complete breakdown of retention rules by province, including what happens when records are requested for legal proceedings, see our guide to incident report retention and confidentiality in Canada.

Best Practices for Filling Out Incident Report Forms

Every company must have a protocol for incident reporting. Only people of authority should be given access to this document. They can use it for documentation of events, management of risks, and creation of safety measures as mandated by law. The following best practices should be observed when filling out the form:

  1. Practice a sense of urgency. Fill out the report form and file it within 24 hours.
  2. Include small details and all pertinent data.
  3. The supervisor should verify the information in the report.
  4. Only the person that is directly involved in the incident should fill out the form.
  5. Be thorough and avoid making corrections after the fact.
  6. Proofread carefully.
  7. Do not assume the reader will understand general statements.
  8. Keep it confidential and do not let unauthorized individuals read the information.
  9. Sign the document when done.
  10. Inform the police or healthcare professionals when necessary.

Paper vs. Digital Incident Reporting

Comparison of paper versus digital incident reporting showing advantages of digital systems: mandatory fields, photo uploads, automatic timestamps, access controls, instant notifications, and fast retrieval

Paper forms still work, but they create problems that compound over time. Paper gets lost in the truck, coffee-stained, or filed in a cabinet nobody opens until an auditor asks for it. Digital incident reporting solves the most common failure points:

  • Mandatory fields prevent incomplete reports (no more "forgot to write the date")
  • Photo and document uploads from the field, attached directly to the report
  • Automatic timestamps proving when the report was created and submitted
  • Access controls enforcing who can view, edit, and sign
  • Instant notification to supervisors and safety managers the moment a report is filed
  • Search and retrieval when an auditor or regulator asks for a specific report from 18 months ago

Common Mistakes to Avoid

Five common incident report mistakes to avoid: waiting too long, writing opinions, leaving out context, forgetting near misses, and not involving the joint health and safety committee
  • Waiting too long to document. Memory fades fast. A report written 3 days after the incident will miss critical details.
  • Writing opinions instead of facts. "He should have known better" belongs nowhere in an incident report.
  • Leaving out the "before" and "after." What was happening leading up to the incident? What actions were taken immediately after?
  • Forgetting near misses. If nobody got hurt, many crews skip the report. That is how patterns go undetected until someone does get hurt.
  • Not involving the joint health and safety committee. In most provinces, the JHSC or health and safety representative must be notified and involved in the investigation.

Every employee should undergo safety training that covers how to handle and report incidents at work. This way, they will know how to write an incident report when something happens. Going paperless with a digital incident reporting system can also help you avoid losing crucial documents.

Frequently Asked Questions

What is an incident report?

An incident report is a formal written document that records the facts of any workplace event resulting in injury, illness, property damage, or a near miss. It captures who was involved, what happened, when and where it occurred, and what actions were taken. Incident reports are legal documents used for regulatory compliance, insurance claims, and identifying corrective actions to prevent future occurrences.

How do you write an incident report at work?

To write an incident report at work, document the basic facts immediately: who was involved, what happened, when and where it occurred, and any injuries or damage. Be objective, stick to facts (not opinions), include witness statements, and have a supervisor review and sign it. File the report within 24 hours while details are still fresh. Use a standardized template to ensure nothing is missed.

When should an incident report be completed?

An incident report should be completed as soon as possible after the event, ideally within 24 hours. Most Canadian provincial workplace safety regulations require prompt reporting, with specific incidents (such as fatalities, critical injuries, or certain hazardous occurrences) requiring immediate notification to the regulator. In British Columbia, employers must submit Form 7 within 72 hours. In Ontario, WSIB Form 7 is due within 3 business days, and a written report to the Ministry of Labour is due within 48 hours for critical injuries.

Are incident reports confidential?

Yes, incident reports typically contain confidential information, including personal health details and employee records. Access should be restricted to authorized personnel only, such as supervisors, safety officers, HR, and regulatory inspectors when required. Proper storage (physical or digital) and access controls are essential to protect the privacy of the individuals involved, in compliance with Canadian privacy legislation such as Alberta's Health Information Act and Ontario's Personal Health Information Protection Act.

How long should you keep incident reports in Canada?

Most Canadian provinces require employers to keep incident investigation reports for a minimum of 3 years. Federally regulated workplaces must retain hazardous occurrence reports for 10 years. Best practice is to keep all incident reports for at least 5 years, and indefinitely for incidents involving fatalities, serious injuries, or hazardous substance exposure. Check your specific provincial requirements, as retention periods for certain records (such as those related to toxic substance exposure) can extend to 30 or 40 years.

What is the difference between an incident report and a near-miss report?

An incident report documents an event that resulted in actual injury, illness, or property damage. A near-miss report documents an event where no harm occurred but easily could have, such as a dropped tool from height that missed a worker. Both are critical for workplace safety. Near-miss reporting helps identify hazards before they cause injuries, and many Canadian safety programs (including COR and SECOR) require near-miss documentation as part of their audit criteria.
