When a Quebec employee files a psychological injury claim with the CNESST, the outcome often comes down to one question: what can the employer actually show?
Not what managers remember. Not what HR believes happened. What’s on file, dated, and consistent.
Since Loi 42 came into force, that question has become more urgent. New legal presumptions now shift the burden of proof onto employers in certain cases, claim deadlines have been extended, and a new regulation on sexual violence prevention is on the way. For Quebec employers, CNESST psychological injury claim documentation is no longer an administrative afterthought. It’s the core of your position.
This guide explains the two main CNESST tracks, what changed, and exactly what you should have on file.
This article is general information, not legal advice. Consult Quebec employment counsel about specific files.
Two Different Tracks at the CNESST
Quebec employers often blur two separate processes, and it helps to keep them distinct.
The labour standards track. Under the Act respecting labour standards (LNT), every employee has the right to a workplace free from psychological harassment, and every employer must prevent it and stop it when they become aware of it (the CNESST’s harassment page summarizes these duties). An employee can file a psychological harassment complaint with the CNESST, generally within two years of the last incident. These files can end up before the Tribunal administratif du travail (TAT).
The workers’ compensation track. Under the Act respecting industrial accidents and occupational diseases (LATMP), an employee can claim that a psychological condition, such as an adjustment disorder, depression, or PTSD, is an employment injury (lésion professionnelle). If accepted, the employee receives income replacement and benefits, and the costs may be charged to the employer’s file, affecting premiums.
The same situation can trigger both tracks at once, plus a civil claim, a grievance, or a wrongful dismissal action. The documentation you keep has to hold up across all of them.
What Loi 42 Changed
On March 27, 2024, Quebec sanctioned Bill 42, An Act to prevent and fight psychological harassment and sexual violence in the workplace. Several of its changes directly affect how psychological injury claims play out.
New presumptions that favour the worker. An injury or illness is now presumed to be work-related when it results from sexual violence committed by the employer, one of its officers, or any worker whose services the employer uses. A second presumption treats an illness appearing within three months of workplace sexual violence as an employment injury. These amendments took effect in September 2024 and put the onus on employers to rebut the presumptions.
In practical terms, if you contest one of these claims, you’re no longer simply responding. You need evidence.
Longer deadlines. For an employment injury resulting from sexual violence, the time limit to file a CNESST claim went from six months to two years. That means an incident from well over a year ago can become a claim today, and your records need to still exist and still be retrievable.
Broader prevention duties. Employers’ obligations now expressly cover psychological harassment from “any person,” including clients, suppliers, and other third parties. Your documentation should capture third-party incidents, not just employee-on-employee conduct.
Harassment policy folded into prevention. The psychological harassment policy now forms an integral part of the prevention program under occupational health and safety law, a requirement that took effect on October 1, 2025.
Stricter limits on medical records. The law now states expressly that employers have no right of access to the worker’s medical file held for the claim, and employers who try to obtain it by any means face fines of up to $10,000. Instead, an employer may designate a health professional, who can provide a summary of the record and an opinion. This makes your own factual workplace records even more important, because you can’t lean on the medical file.
The New Sexual Violence Regulation
The next wave is already published. On May 27, 2026, the Regulation respecting the measures to prevent or put a stop to sexual violence was published in the Gazette officielle du Québec. Most provisions come into force on May 27, 2027, with training obligations following on May 27, 2028.
The regulation sets out new employer obligations covering prevention, training, and the handling of complaints and reports, and it extends beyond the workplace to situations such as work-related social events and incidents involving technology. It also introduces a formal obligation to inform employees in writing about sexual violence risks, prevention measures, and complaint procedures, and requires employers to designate a qualified person to manage complaints and reports.
If your reporting and documentation processes are informal today, the next twelve months are the time to fix them.
Why Documentation Decides These Files
A psychological harassment claim defence in Canada, and particularly in Quebec, rarely turns on a single dramatic piece of evidence. It turns on the pattern the record shows.
Adjudicators ask questions like: Did the employer have a policy, and did employees know about it? When a concern was raised, how fast did someone respond? Were interim measures taken to protect the person? Was the investigation impartial? Were conclusions communicated? Did the conduct stop?
An employer with a clear, timestamped record answering each of those questions is in a fundamentally different position from one piecing together memories and forwarded emails months later. With the burden now on employers in sexual violence cases, actively documenting each file and gathering the facts early is what gives a contestation a real chance of success.
What Quebec Employers Need on File
Here is a practical inventory. Think of it as the file you’d want to hand your lawyer the day a claim arrives.
1. Your policy and proof it was communicated
Keep the current version of your psychological harassment and sexual violence policy, in French, along with previous versions and the dates they changed. Just as important: evidence that employees received it, such as acknowledgement records, onboarding checklists, or posting records. A policy nobody saw offers limited protection.
2. Proof of an accessible reporting channel
You should be able to show that employees had a real, easy way to raise concerns, including anonymously and outside their chain of command. Record where reporting information was posted and when. If an employee later says “there was no way to report,” this is your answer.
3. A timestamped record of every report
For each concern: when it arrived, what it said, how it was categorized, and who received it. The time between a report and your first response is one of the first things an adjudicator looks at.
4. Triage and interim measures
Document what you did immediately: schedule changes, separating the parties, leave, supervision adjustments, referrals to the employee assistance program. Record the reasoning, especially if you decided a measure wasn’t needed.
5. The investigation file
Keep the mandate, who investigated and why they were impartial, interview notes, evidence collected, and the final report. Distinguish clearly between allegations and findings.
6. Outcome and follow-up
Record what was decided, what corrective or disciplinary measures were taken, how the outcome was communicated to the parties, and whether you checked afterward that the behaviour stopped. Follow-up is where many files fall apart.
7. Prevention program records
Because the harassment policy is now part of your prevention program, keep your psychosocial risk identification, action plans, and training records. These show you were preventing, not just reacting. Timing matters here: the grace period for integrating psychosocial risks into prevention programs expires on October 6, 2026.
8. Claim-handling records, without medical files
When a CNESST claim is filed, keep your employer’s notice, correspondence with the CNESST, your designated health professional’s summary, and your contestation steps. Do not keep, request, or circulate the worker’s medical file.
Harassment Documentation and Wrongful Dismissal Risk
Harassment files often end in termination, either of the person found responsible or, in contested situations, of the complainant for unrelated reasons. Either way, wrongful dismissal harassment documentation becomes critical.
If you dismiss someone for harassment, your record must show the investigation was fair and the conclusion was supported. If you dismiss or discipline someone who previously reported harassment, expect a reprisal argument. Under the LNT, an employee with two or more years of continuous service can also contest a dismissal made without good and sufficient cause. In both scenarios, a clean, contemporaneous audit trail showing the timeline of reports, actions, and decisions is your strongest protection.
Privacy: What You Should Not Keep
Documentation doesn’t mean collecting everything. Quebec’s private-sector privacy law, as amended by Law 25, requires you to protect personal information, limit access, and apply retention rules. Harassment files are highly sensitive. Store them securely, restrict them to people who need them, keep them in Quebec or Canada where possible, and never mix medical information obtained outside the proper channels into HR files.

Common Documentation Gaps We See
The same problems come up repeatedly: complaints raised verbally and never written down; reports buried in personal inboxes of managers who have since left; no record of when the employer first became aware; investigations with no written mandate; outcomes never communicated; policies available only in English; and records that were edited after the fact with no way to prove what changed.
Every one of these gaps weakens your position, and every one is preventable.
How SignalitUP Supports CNESST-Ready Documentation
SignalitUP is a CNESST harassment reporting tool built for Quebec employers. Employees scan a QR code with their own phone, with no app and no account, and submit a report in French or English, anonymously if they choose. Our French content is written by Quebec writers, not machine-translated.
Every signal and every follow-up is logged in a timestamped, tamper-evident audit trail. Two-way anonymous chat lets investigators ask questions without exposing the reporter. Data is hosted in Canada. As HR audit trail software for workplace claims, it gives you the record you’ll need when a complaint becomes a CNESST file, a TAT hearing, or a lawsuit.
