How Long Do I Have to Sue for Wrongful Dismissal in Ontario?

Published on: June 21, 2025

They fired you weeks—or maybe four months—ago. You didn’t sign any documents that the employer gave you on termination. And now, that nagging question won’t go away: “Did I wait too long to do something about it?

The good news? You may still have time to act. However, it’s important to understand that in Ontario, the law does not permit individuals to pursue legal action indefinitely after termination from their job. If you are contemplating taking legal steps following your dismissal, it is crucial to be aware of the specific deadlines that apply to your situation, as well as the reasons why timing is of the essence.

In Ontario, the limitations period for filing a claim related to wrongful dismissal or employment-related disputes is governed by the Limitations Act.
● You generally have two years from the date of your termination to initiate a legal claim.
● If you were let go on a specific date, you must file your claim within two years of that date.
● Failing to file within this time frame could result in your claim being barred.
● If barred, you would lose your right to seek compensation or other remedies.

First, the legal process can be complex and time-consuming.
Gathering evidence, consulting with legal professionals, and preparing your case can take considerable time. Therefore, the sooner you begin this process, the better your chances of meeting the deadline. Additionally, acting promptly can help preserve important evidence and witness testimonies that may be crucial to your case.

Ontario’s Legal Deadline: The 2-Year Limitation Period

Under Ontario’s Limitations Act, you generally have 2 years from the date of your dismissal to file a wrongful dismissal lawsuit. That means you must take formal legal action within that timeframe—or risk losing your right to do so.

This two-year period applies to court claims for damages (like compensation for lost income or benefits) due to wrongful dismissal, not to complaints filed through the Ministry of Labour.

Wrongful dismissal in Ontario, get the severance package you deserve.

When Does the 2-Year Clock Start?

The countdown doesn’t wait for you to feel ready. The 2-year clock usually begins on the date you were let go. That might be:

  1. The day you received your termination letter
  2. The day your employment ended (if you were given working notice)
  3. The day your employer stopped providing work, even without a formal letter

It does not start when your severance runs out, when your job search ends, or when you “make up your mind.” Waiting can cost you.

Are There Exceptions to the Rule?

Sometimes—but don’t count on it. Ontario courts rarely bend the two-year rule unless you can prove a clear legal exception.

Potential exceptions include:

  1. You were medically incapable of pursuing a claim
  2. You didn’t discover the dismissal was wrongful until later (rare and difficult to argue)

Even in those situations, time matters. The longer you wait, the harder your case becomes.

Why Acting Early Helps Your Case

Even if you’re within the 2-year limit, waiting can hurt:

  • Evidence fades: Emails, documents, and messages can get lost.
  • Memories blur: Key details may be forgotten by you or witnesses.
  • Negotiating leverage drops: Employers are less responsive the longer you wait.

Acting early gives your lawyer the time and tools needed to build a strong case.

Acting early helps you case for get the severance pay you deserve.

Real-Life Example: Don’t Assume It’s Too Late

A marketing coordinator came to us 20 months after being fired. She hadn’t signed a release, but she assumed she’d missed the deadline. Turns out, she still had four months to act.

We reviewed her termination, spotted flaws in the severance package, and filed a claim. Within weeks, she walked away with a fair settlement that was 3x her original offer.

What to Do If You’ve Been Terminated

If you’re unsure whether your termination was legal or not, take these steps:

  • Don’t sign anything under pressure
  • Gather key documents: Offer letters, termination letters, emails, contracts
  • Write the timeline: When were you told? When did you stop working?
  • Get legal advice ASAP: Don’t wait to “see what happens”

The sooner you get clarity, the more options you have.

Final Word: Deadlines Matter, But So Does Action

You may have two years to sue, but you don’t want to wait that long to speak to someone.
Legal deadlines can feel confusing—but you don’t have to figure it out alone.
