An AI tool that helps a supervisor produce a faster, more complete incident report doesn't change what that report is for in law. If it exists because a regulator required it, it isn't a litigation document — whatever software drafted it.
Key takeaways
Two different questions get run together on a job site after an incident, and an AI drafting tool makes it easier to blur them further because it produces a document fast: what does the law require you to file, and what is legally privileged. The first question has real, sourced deadlines. The second is a genuinely harder legal question that this article deliberately doesn't try to answer for you — it explains why, and what to check instead.
In Ontario, the reporting obligations sit in Part VII of the Occupational Health and Safety Act, under O. Reg. 420/21. Where a person is killed or critically injured, the employer and constructor must “immediately” notify the Ministry's Health and Safety Contact Centre, the joint health and safety committee or representative, and the union, by telephone or other direct means and “within 48 hours” send a written report to a Director of the Ministry setting out the circumstances Lesser injuries — an accident, explosion, fire or incident of workplace violence that leaves someone needing medical attention but not critically injured — generally require written notice to the joint health and safety committee and the union within four days.
British Columbia's clock runs differently and is set out directly by the regulator: “Employers must complete a preliminary investigation and accompanying report within 48 hours of an incident.” and “A full investigation and report must be completed within 30 days of the incident.” Section 69 of the Workers Compensation Act sets out what incidents an employer must investigate, and reports must meet the content requirements in WorkSafeBC Prevention Policy Items P2-71-1 and P2-72-1 to comply with sections 71(2)(a) and 72(2)(a) of the Act.
WSIB's own operational policy on employer reporting, published 2023-09-29 and applying to accidents on or after that date, sets the Ontario trigger: an employer must report if a worker requires health care and is absent from regular work, earns less than regular pay, or requires modified work at regular pay for more than seven calendar days following the accident Once that trigger is met, “Your employer must report your injury or illness to us within three business days and give you a copy of their report.”
None of these clocks are optional, and none of them start because litigation looks likely. They start because the statute or the Board's policy says a report is due — which is exactly why a document created to meet one of them sits on the compliance side of the line, not the litigation-preparation side.
Litigation privilege, under Canadian common law, protects communications and documents created for the dominant purpose of existing or reasonably anticipated litigation. A document created because a statute or a regulator's policy required it — the OHSA notice, the WorkSafeBC preliminary and full investigation reports, the WSIB Form — exists for a regulatory purpose. That is generally a strong indicator against privilege attaching to that specific document, because the document would have been created regardless of any litigation risk.
Whether a separate memo, an email to counsel, or a document your lawyer specifically directed be prepared in anticipation of a claim is privileged is a different and genuinely fact-specific question — one that turns on why that particular document was created, who asked for it, and what else exists that served the same regulatory purpose. This is not a question this article, or any general guidance, can answer for a specific file. If litigation is genuinely anticipated alongside a reportable incident, route that separate work through counsel from the outset and keep it clearly apart from the statutory compliance file, and get your own lawyer's view on the specific document rather than assuming either way.
Using a tool to transcribe a dictated account, structure a chronology, or complete the fields a WorkSafeBC or WSIB form requires doesn't change what the resulting document is for. It's still the report the statute or policy required, produced faster. The Canadian Centre for Occupational Health and Safety's guidance on generative AI is a useful general caution to carry into this specific use: outputs “can be incorrect”, “might not take certain factors into account”, and “can be biased” and the Cyber Centre flags “privacy of data” as a named risk — “users may unknowingly provide sensitive corporate data or personally identifiable information (PII) in their AI queries and prompts”
The practical version: a model can draft the compliance report faster, and a named person still has to verify every fact in it before it's filed, exactly as it would if a junior staffer had typed the first draft. The tool's speed doesn't change the review obligation, and it doesn't change which side of the privilege line the resulting document sits on.
Draft vs decide
A tool may: transcribe a dictated account, structure the chronology against the form's required fields, and flag what's still missing before the deadline.
Only a person decides: the finding of cause, whether a separate document is being created for litigation rather than compliance, and what — if anything — should be routed through counsel instead of the standard reporting workflow.
A framer falls from height on a mid-rise residential site in British Columbia and is taken to hospital with a fractured wrist — not a critical injury under Ontario's test (this is a BC site, so BC's own thresholds apply), but a reportable incident under WorkSafeBC's rules. The superintendent uses a dictation-to-report tool to produce the 48-hour preliminary investigation report the same afternoon: photographs of the opening, a description of the guardrail that was removed, and a chronology built from his dictated account.
Two days later, the site's insurer asks whether the fall exposes the general contractor to a claim from the framer's own employer, a subcontractor. The site's lawyer is brought in at that point and asks for a separate memo assessing exposure. That memo — created specifically at counsel's request, after litigation became a live possibility, and serving no regulatory filing purpose of its own — sits in a meaningfully different position from the WorkSafeBC preliminary and full investigation reports, which existed because the Workers Compensation Act required them regardless of whether a claim ever materialized. Whether the memo is actually privileged still depends on facts a lawyer needs to assess directly; the point worth taking from the example is that the two documents were created for different reasons, and treating them the same because a similar tool drafted both would be the mistake.
The full-investigation report is still due at day 30 either way — how camera footage from the site fits into the same file and how long the underlying records have to be kept cover the two records questions that tend to surface once that file starts circulating.
The tool itself isn't the risk. The risk is treating a document that exists to satisfy a statutory reporting obligation as if it were privileged when it isn't, because privilege was never available for that document in the first place — whether or not AI helped write it. Confirm with counsel before withholding a regulator-required report on privilege grounds.
The reports created to meet OHSA, WorkSafeBC or WSIB reporting obligations exist specifically to be filed with or available to the regulator — they're not documents an employer can generally withhold from the body that required them in the first place.
Not necessarily — the tool can still draft the statutory report. The change to make is procedural: keep any litigation-focused analysis in a clearly separate document, created at counsel's direction, rather than folding it into the same file as the regulatory report.
A 30-minute call is enough to tell you whether AI pays for itself here.
