In Ontario, you generally have exactly two years to file a wrongful dismissal lawsuit. Under the “discoverability rule,” this 2-year limitation clock typically starts ticking on the exact date you are formally notified of your termination, not necessarily your last day of work or when your salary continuance ends.
Losing your job is a traumatic experience, and many residents in Ontario take weeks or even months to recover before considering their legal options. While it is normal to need a break, waiting too long to ask a law firm for help can completely destroy your right to collect severance pay.
Ontario law enforces strict deadlines for taking civil action against a former employer. This deadline is known as the “statute of limitations.” If you miss this window by even one day, the court will permanently block your claim, no matter how badly the company treated you or how much money you are owed.
A common mistake employees make in Toronto, Mississauga, and Ottawa is misunderstanding when this clock actually starts. Below, we break down the “discoverability rule” and how you can protect your right to common law severance pay before time runs out. 📅
Step-by-Step Process for Understanding Limitation Periods in Ontario
The Ontario Limitations Act, 2002 sets a standard 2-year deadline for most civil lawsuits, including wrongful dismissal. However, deciding the exact “start date” can be tricky. Here is how you should evaluate your timeline.
Step 1: Identify the Date of “Clear and Unequivocal” Notice
The core principle of the discoverability rule is that the clock starts when you first “discover” you have suffered a loss. In employment law, this usually means the exact day your manager hands you a termination letter or tells you clearly that your job is ending.
For example, if on January 1, your employer tells you that you will be let go on March 1, the 2-year clock likely starts on January 1. You knew on that day that the company was ending your contract without offering a proper common law severance package.
Step 2: Do Not Wait for Salary Continuance to End
Many companies pay severance in the form of “salary continuance,” meaning they keep you on the payroll for a few months instead of giving you a lump sum. A massive legal trap is waiting until these payments stop before contacting a lawyer.
The limitation period does not pause just because you are still receiving a bi-weekly cheque. Your 2-year deadline is still ticking from the original date you were notified of the termination. Always have a lawyer review the severance offer immediately.
Step 3: Recognize Constructive Dismissal Deadlines
If you were not formally fired, but your employer drastically cut your pay, demoted you, or created a toxic workplace, you might be facing a “constructive dismissal.” 🚨
In these cases, the discoverability date is usually the day the massive change took effect (e.g., the day your salary was actually reduced). Because constructive dismissal timelines can be highly debated, contacting a local law firm is critical to lock in your correct filing date.
Step 4: Tolling Agreements or Filing a Statement of Claim
If your 2-year deadline is approaching rapidly, your lawyer must take immediate action. To protect your rights, they will file a formal “Statement of Claim” at the Superior Court of Justice.
Alternatively, your lawyer and the company’s legal team can sign a “Tolling Agreement.” This is a legally binding contract that temporarily pauses the limitation clock, giving both sides more time to negotiate a severance package without forcing an immediate lawsuit.
Crucial Dates That Trigger the 2-Year Clock
| Termination Scenario | When Does the 2-Year Clock Generally Start? |
|---|---|
| Immediate Firing (No Notice) | The exact day you are told you are fired and asked to leave the building. |
| Working Notice | The day you are given the written notice that your job will end in the future. |
| Constructive Dismissal (Pay Cut) | The day the employer officially enforces the pay reduction or demotion. |
How Much Does it Cost to Sue in Ontario?
Filing a claim before your limitation period expires involves some standard costs. As of May 2026, here is what to expect:
- Initial Consultation: Reviewing your timeline and severance offer generally costs between $300 and $500 CAD.
- Court Filing Fee: Issuing a Statement of Claim at the Superior Court of Justice costs roughly $242 CAD, locking in your lawsuit before the 2-year deadline.
- Contingency Fees: Most Ontario employment lawyers will represent you for a percentage of the final settlement, typically around 30%.
How Long Does the Process Take?
Missing your deadline means zero compensation. If you file on time, here are the typical timelines:
- Filing the Lawsuit: A law firm can draft and file a Statement of Claim in a matter of 1 to 2 weeks if your deadline is an emergency.
- Negotiation Phase: Once the lawsuit is filed, most companies settle within 4 to 8 months through mediation.
- Full Trial: If the employer fights the claim, it can take 1.5 to 2 years to get a final judge’s ruling at the Superior Court.
Frequently Asked Questions (FAQ)
Can the 2-year limitation period ever be extended?
In extremely rare cases, such as severe physical or mental incapacity where you were medically unable to understand your rights, a court might extend the deadline. However, you should never rely on this exception.
What happens if I miss the 2-year deadline by one week?
Under the Ontario Limitations Act, your claim is generally “statute-barred.” This means the court will throw out your lawsuit, and the employer legally owes you nothing, regardless of how unfair the termination was.
Does filing for Employment Insurance (EI) stop the clock?
No. Applying for EI with Service Canada has absolutely no impact on the provincial 2-year limitation period. The clock continues to run while you collect your unemployment benefits.
What if I complain to the Ministry of Labour instead?
Filing an Employment Standards Act (ESA) complaint with the Ministry of Labour limits your compensation to statutory minimums. More importantly, it can legally block you from suing for the much larger common law severance in civil court.
