How to report workplace harassment in Ontario is a question that matters from both sides of the employment relationship. Employees need to know their options and protections. Employers need reporting systems that comply with OHSA, surface complaints early, and produce defensible records.
For the employer perspective on investigations, see our Complete Guide to Workplace Investigations in Ontario. This guide addresses both perspectives — because effective reporting serves everyone. Complaints that are reported early, documented properly, and handled promptly produce better outcomes for complainants, respondents, and the organization.
The Employee Perspective: How to Report
If you are experiencing workplace harassment in Ontario, you have multiple reporting options. Knowing them — and understanding what happens after you report — reduces the uncertainty that keeps many workers silent.
Internal reporting channels. Your employer is required under OHSA to have a harassment policy that includes a complaint procedure. This typically provides several options: your direct manager or supervisor, your HR department or designated HR contact, a senior leader outside your reporting chain, and in some organizations, an anonymous hotline or third-party intake service.
Start with whichever channel feels most accessible and safe. If your manager is the person harassing you, go directly to HR or the next channel in the policy. If you do not trust any internal channel, you have external options.
External reporting options. You can report workplace harassment to external bodies without exhausting internal options first.
The Ministry of Labour Health and Safety Contact Centre (1-877-202-0008) handles complaints about employer non-compliance with OHSA, including failure to have a harassment policy, failure to investigate, and inadequate investigation. An inspector can be assigned to investigate the employer's compliance.
The Human Rights Tribunal of Ontario handles complaints where harassment is linked to a protected ground (race, sex, disability, age, etc.). Applications must generally be filed within one year of the last incident of harassment. The HRTO can award damages, reinstatement, and systemic remedies.
What to document. Whether you report internally or externally, documentation strengthens your position. Keep a contemporaneous record of each incident — date, time, location, what was said or done, who was present. Save emails, text messages, and any other communications related to the harassment. Note any witnesses to each incident. Document the impact on your work and wellbeing.
Protection against reprisal. OHSA s.50 makes it illegal for your employer to penalize you for reporting harassment. Reprisal includes termination or constructive dismissal, demotion or reassignment to less desirable work, reduction in hours or pay, exclusion from meetings, projects, or opportunities, negative performance reviews that appear connected to your complaint, and any other adverse change to your working conditions.
If you experience reprisal, document it and report it separately. Reprisal complaints can be filed with the Ontario Labour Relations Board and carry significant penalties for employers.

The Employer Perspective: Building Effective Reporting Systems
For employers, the reporting system is where prevention meets response. A system that employees trust and use is your best tool for early intervention — and your strongest defence against claims that you failed to act.
Multiple channels are non-negotiable. OHSA requires a complaint mechanism, and practical defensibility requires multiple channels. At minimum, provide direct manager, HR contact, senior executive, and an external option for situations where all internal channels are compromised.
Each channel must be staffed by someone who knows what to do when a complaint arrives. A reporting channel that leads to a manager who has never been trained on complaint intake is a liability, not a system.
Lower the barriers. Every barrier you place between the worker and the report reduces the likelihood that complaints surface early — when they are easiest to address and least likely to escalate to litigation.
Do not require written complaints as a precondition for action. Accept verbal reports and document them yourself. Do not require the complainant to confront the respondent before reporting. Do not require the complainant to "try to work it out" first. Do not require a specific form or format.
The goal is to learn about potential harassment as early as possible. Make reporting easy, not onerous.
Train managers as the front line. Most initial harassment reports go to the complainant's direct manager. Managers need practical training on how to receive a complaint without minimizing, dismissing, or investigating on their own. They should know how to listen without promising outcomes, document the substance of the report, not promise confidentiality they cannot deliver, escalate to HR or the designated investigation lead immediately, and not take any action toward the respondent without consulting HR.
Managers who say "I'll handle it" and attempt informal resolution of harassment complaints create enormous risk. The complaint is not documented, the investigation obligation is not triggered, and the employer loses the ability to demonstrate a defensible response.
Anonymous reporting. Consider implementing an anonymous reporting mechanism — a hotline, web form, or third-party intake service. Anonymous reports can be more difficult to investigate (you may not be able to interview the complainant), but they surface issues that workers are otherwise reluctant to report. Treat anonymous reports seriously: investigate to the extent possible with available information.
What Happens After a Report
Understanding the post-report process reduces anxiety for complainants and ensures employers follow through on their obligations.
Acknowledgment. The complaint should be acknowledged promptly — within 24-48 hours. Inform the complainant that their report has been received, explain the next steps, provide an expected timeline, identify who will be in contact with them going forward, and reiterate the prohibition against reprisal.
Assessment. The employer assesses whether the complaint triggers the investigation obligation (it almost always does under OHSA), what interim measures are needed, whether an internal or external investigator is appropriate, and the scope and timeline for the investigation.
Investigation. The investigation proceeds through the standard process: interviews with the complainant, respondent, and witnesses; evidence collection and analysis; credibility assessment where accounts conflict; and findings on each allegation.
Outcome communication. Both the complainant and respondent are informed of the results and any corrective action, as required by OHSA s.32.0.7(1)(b).
Follow-up. The employer monitors the workplace post-investigation, checks in with the complainant periodically, and watches for reprisal.
Common Reporting Failures and How to Fix Them
Failure: complaints go into a black hole. Workers report, hear nothing for weeks, and conclude the process is performative. Fix: establish and communicate specific timelines for acknowledgment (24-48 hours), investigation initiation (within one week), and completion (2-4 weeks for straightforward cases).
Failure: managers investigate on their own. A manager receives a complaint and decides to "look into it" by talking to the respondent informally. This is not an investigation — it is a conversation that may contaminate evidence and alert the respondent. Fix: train managers to document and escalate, not investigate.
Failure: retaliation after reporting. The complainant reports, and their next performance review is suddenly negative, their project assignments change, or they are excluded from meetings. Fix: flag all performance actions involving active complainants for HR review before implementation.
Failure: no follow-up after resolution. The investigation concludes, corrective action is taken, and the employer moves on. The complainant is left wondering whether the workplace is actually safe. Fix: structured check-ins at 30, 60, and 90 days with documentation.
Making Reporting Work for Your Organization
Effective reporting is not a compliance checkbox — it is an operational advantage. Organizations where workers report early resolve issues before they escalate to litigation, demonstrate a defensible response to regulators and tribunals, retain employees who might otherwise leave (or sue), and build a culture where harassment is actually addressed rather than tolerated.
