Once you've filed a complaint, a workplace harassment investigation can feel like it's happening to you rather than for you. Ontario law gives employees specific rights during that process, even though the investigation itself is usually run by the employer, not a court or tribunal.

Employers covered by the Occupational Health and Safety Act are generally required to investigate harassment complaints, and to do so in a way that is appropriate in the circumstances. What "appropriate" means depends on the situation, but some baseline protections apply across the board.

This article sets out what you can generally expect, and what to do if the process doesn't measure up.

What You're Generally Entitled To

The Investigation Process — What Usually Happens

  1. Intake. You report the harassment, generally in writing, describing what happened.
  2. Assignment. The employer designates someone to investigate, ideally someone not implicated in the complaint.
  3. Interviews. The investigator speaks with you, the person you complained about, and relevant witnesses.
  4. Findings. The investigator reaches conclusions about what happened, based on the evidence gathered.
  5. Outcome. The employer takes corrective action if warranted, and communicates the general outcome to you.

The exact steps, and how long each takes, vary by workplace and complexity, and the law does not set a fixed timeline for every stage. A fair process matters more than a fast one, but an investigation that drags on indefinitely, or never seems to move, can itself be a problem worth raising.

What Can Go Wrong — and What to Do

ProblemWhat it might meanWhat you can do
The investigator is close to the person you complained aboutThe process may not be neutralAsk for a different investigator; document the concern
You're never interviewedThe investigation may be inadequateRaise it in writing; keep a copy
You face changed treatment after complainingPossible reprisalThis is itself unlawful — document it and get advice
No outcome is ever communicatedThe process may have stalled or been abandonedFollow up in writing; consider external options

When to Look Beyond the Internal Process

If the internal investigation is compromised, unreasonably delayed, or simply never happens, you are not required to wait indefinitely. A complaint to the Ministry of Labour about the employer's compliance, or a Human Rights Tribunal of Ontario application if the harassment is tied to a protected ground, remain available regardless of how the internal process unfolds.

Preparing for Your Interview

Being organized doesn't make your account less genuine — it makes it easier for an investigator to act on what you've reported.

Frequently asked questions

Can I bring a support person to my interview?

Many employers allow this, and it's reasonable to ask, though it isn't automatically guaranteed by law in every workplace. If it's refused, note that and continue to participate as best you can.

What if the person I complained about is still my manager during the investigation?

Ask whether temporary reporting changes can be made while the investigation proceeds. If the employer refuses and you experience ongoing harm, that itself may be worth raising as a separate concern.

Do I get to see the full investigation report?

Not necessarily in full. Employers commonly share the outcome and general findings rather than the entire report, particularly where it touches on another employee's personal information.

What if I disagree with the investigation's conclusion?

You can raise your disagreement with the employer, but if you believe the process or outcome was inadequate, external routes like a Ministry of Labour complaint or a Human Rights Tribunal application remain available.

Can I be disciplined for how I acted during the situation being investigated?

Possibly, if your own conduct is also at issue — an investigation can sometimes surface concerns about more than one person involved. That's different from being disciplined simply for having made the complaint, which is unlawful reprisal.
