When you're deciding how to report workplace harassment in Ontario, the choice isn't just "who do I tell" — it's which process actually fits your situation. An internal complaint, a Ministry of Labour complaint, and a Human Rights Tribunal of Ontario application are all real options, and each does a different job.

Some employees raise the issue internally first and escalate only if that fails. Others go straight to an external option because they've lost confidence in their employer's process, or because the person responsible is the one who would normally handle the complaint. Neither approach is automatically wrong.

This article compares the internal and external routes so you can make an informed choice about where to start.

Telling Your Employer First

Most Ontario workplaces are required to have a harassment policy and a defined complaint process under the Occupational Health and Safety Act. Raising it internally typically means:

This route can be fast and can preserve the working relationship, but it depends heavily on your employer actually running a fair, competent process.

Going to the Ministry of Labour

The Ministry of Labour oversees whether employers are meeting their occupational health and safety obligations, including their duty to have a harassment program and to investigate complaints. A complaint here generally leads to scrutiny of the employer's compliance and process — it isn't designed to award you personal compensation for what happened.

Applying to the Human Rights Tribunal of Ontario

If the harassment is connected to a protected ground under the Human Rights Code — such as sex, race, disability, or age — a Human Rights Tribunal of Ontario application can seek a personal remedy for the harm you experienced, separate from any internal process.

Choosing Where to Start

  1. Ask whether you trust your employer's internal process to be fair and confidential.
  2. Consider whether the person responsible holds a role that would normally receive or handle your complaint.
  3. Decide whether you want the conduct addressed, personal compensation, or both.
  4. Check whether any relevant deadlines are already running before you decide to wait.
  5. Talk to a lawyer if you're unsure — the routes can sometimes be combined, but not always without limits.

What to Put in Your Report, However You Send It

Whichever route you choose, a clear, factual written account tends to carry more weight than a verbal complaint alone. A useful report generally includes:

A vague complaint — "things have been uncomfortable lately" — is much harder for anyone, internal or external, to act on than a specific, dated account.

Frequently asked questions

Do I have to tell my employer before going to the Ministry of Labour or the Tribunal?

Generally no, though some employers' policies encourage internal reporting first. You are not required to exhaust an internal process before using an external one, particularly if you have good reason not to trust it.

What if I already raised it internally and nothing happened?

A failed or mishandled internal complaint doesn't close off external options. In fact, it can support your case by showing the employer was on notice and didn't act.

Can I stay anonymous?

Some internal policies allow anonymous reporting for awareness purposes, but a meaningful investigation, and any external complaint or application, generally requires you to be identified to at least some degree.

Is there a deadline?

Yes, and it varies by route — some deadlines are considerably shorter than people expect. Don't wait to find out which one applies to you.

What if I'm not sure the conduct is serious enough to report?

If it made you uncomfortable and it's connected to your work, it's generally worth documenting even if you're unsure whether to formally report it yet. A pattern that seems minor incident-by-incident can look very different once it's written down and considered as a whole.
