AI is genuinely good at the part of an incident report that gets skipped — turning a rushed verbal account and a folder of photos into a complete, structured document. It is the wrong tool for the part that matters most, which is deciding what caused the incident.
Key takeaways
A site supervisor at 4:40 on a Friday has a worker at a clinic, a crew to send home, and a report to write. The report is the thing that slips. AI closes that gap: four minutes of dictation and a dozen photographs become a structured first draft before he leaves the trailer. What it does not do is decide why the incident happened, and treating a model's guess as a finding is how a report becomes a liability rather than a record.
In Ontario, the notice obligations sit in Part VII of the Occupational Health and Safety Act. Per the ministry's guide to the Act, if a person is critically injured or killed at the workplace, the employer and the constructor must immediately notify, by telephone or other direct means, an inspector of the Ministry of Labour, Immigration, Training and Skills Development, the joint health and safety committee or health and safety representative, and the trade union if there is one — and within 48 hours send a written report to a Director of the Ministry setting out the circumstances.
The same guide sets out the quieter deadlines that catch small contractors. Where an accident, explosion, fire or incident of workplace violence leaves someone needing medical attention or unable to do their usual work, but nobody is killed or critically injured, written notice goes to the committee and the union within four days. An occupational illness, or a claim for one filed with the WSIB, is also four days. And on a construction project, specified events — a premature or unexpected explosion, fire, flood, inrush of water, failure of equipment, a cave-in or subsidence — require written notice within two days even where nobody was hurt.
Compensation reporting is a separate obligation with its own clock. The WSIB requires an employer to report within three business days of learning of an injury or illness where the worker needs treatment from a health professional, is absent from work, earns less than regular pay, or needs modified work at regular pay for more than seven calendar days. You must give the worker a copy and pay a full day's wages for the day of the incident; if first aid was the only treatment and no time or pay was lost, no report is needed. The WSIB also states plainly that it is against the law to discourage reporting, and that penalties apply for not reporting, reporting late, or giving false or inaccurate details.
In British Columbia the equivalent is 72 hours: WorkSafeBC requires employers to report a worker's injury or illness within 72 hours of becoming aware of it, and to report serious incidents and fatalities immediately by calling the Prevention Information Line. Software does not move any of these dates. It only decides whether the document that has to exist by then is a coherent record or three lines typed at midnight.
Four jobs, all clerical: it transcribes the dictated account, maps it onto the fields your form requires so nothing is left blank, drafts the sequence of events in order, and produces a plain-language or translated version for the worker's copy. The Canadian Centre for Occupational Health and Safety lists exactly this among AI's plausible safety uses — assisting in writing safety documents and translating complex requirements into accessible language — while warning in the same fact sheet that AI outputs can be inaccurate, outdated or out of context, that models hallucinate, and that qualified professionals should review AI-generated content before it is used to make decisions.
A language model completes patterns. Given a fall from a ladder and nothing else, it will supply a plausible-sounding cause, because plausible-sounding text is what it produces — which is precisely what an investigation is supposed to resist. CCOHS's guidance on incident investigation makes the point that even in seemingly straightforward incidents there is seldom a single cause, that direct causes (unsafe conditions or acts) must be separated from indirect ones (training, supervision, workplace design, management programs), and that the purpose is to find facts leading to corrective action rather than to find fault.
It rules out two other tempting uses. Witnesses should be interviewed separately and the interviewer should not prompt or ask leading questions — so having a model tidy a witness account into fluent prose substitutes the model's words for that person's, which is the opposite of what the file needs. And CCOHS is explicit that recommendations should never concern disciplining anyone at fault; that belongs in normal personnel procedures.
Draft vs decide
The model may draft: the chronology, the description of the location and conditions, the completeness check against your form, the list of what is still unknown, the corrective-action table, the plain-language copy for the worker.
Only a person writes: the finding of cause, the classification of severity, the witness's account, anything characterizing a worker's conduct, and the signature.
First aid and the statutory phone calls come first. Then, per CCOHS, preserve the evidence while it still exists: photographs of the general area and of specific items before anything is moved, the positions of the people and equipment involved, weather, lighting, time of day, and any video footage before it is overwritten.
Then dictate, and keep the recording — four minutes into a phone within the hour beats twenty minutes of typing on Monday. The model produces the structured draft, working the sequence backwards from the moment of the incident, which is the drafting method CCOHS recommends since that draft becomes part of the final report anyway. Finally a named person edits. CCOHS asks that each conclusion be checked against whether it rests on physical evidence, an eyewitness account or an assumption, and that the report say so where doubt exists. Marking those three categories is also the fastest way to catch anything the model invented, because invented statements have no category.
An eleven-unit stacked townhouse site in Ontario. A framer steps into an unguarded floor opening, twists an ankle, is driven to a clinic and is off two days. Not a critical injury, so the immediate-notice and 48-hour rules do not apply — but written notice to the joint health and safety committee and the union is due within four days, and the WSIB report within three business days.
The superintendent photographs the opening, the surrounding guard rail and the removed section of plywood, then dictates four minutes covering who, where, when, what he saw, who was on the crew, and what the morning inspection had recorded. The model returns a filled form, a chronological narrative, a short list headed "not established" — who removed the plywood and when — and a corrective-action table.
He then makes three edits: adding that the morning inspection record shows the opening covered and marked at 07:15; deleting a sentence in which the model attributed the incident to fatigue, because nobody mentioned fatigue; and replacing "the worker failed to notice" with a description of what was and was not visible from the approach. Fifteen minutes, and the record is defensible. Cause is left to the investigation, which is where it belongs.
Incident files fill with images of workers, and increasingly with camera and wearable data. That is a privacy question before it is a technology question — our sister firm sets out the ground rules in this note on workplace video surveillance and privacy law in Ontario. CCOHS adds the AI-specific caution: do not enter personal or sensitive information into an AI system unless its privacy and security measures are understood and verified and your policy allows it.
No. The report is filed through the WSIB's online services or on the employer's report of injury (Form 7), by your business, and you must give the worker a copy. AI prepares the content that goes into it.
The Act cares whether notice was given on time and whether the content is accurate and complete. Who typed the first draft is not the test. What would damage you is an inaccurate statement of fact, or an invented cause that somebody signed without checking.
That is the strongest case for it. CCOHS treats an incident as including events that could have caused injury or damage but did not, and near misses are exactly what goes unrecorded when a report costs half an hour to write. At four minutes of dictation, you get the data set that lets you fix things before the injury.
A 30-minute call is enough to tell you whether AI pays for itself here.
