1. What Wrongful Dismissal Actually Means in Ontario

Many people assume “wrongful dismissal” means they were fired unfairly, without reason, or unjustly. That is a common misconception. In Ontario law, wrongful dismissal has a specific technical meaning:

Wrongful dismissal = being fired without receiving proper notice or pay in lieu of notice. It does not mean the firing was morally wrong or that you did nothing to deserve it. An employer can fire you for any reason (or no reason at all) without causing a wrongful dismissal, as long as they give you proper notice or pay you out. The “wrong” in wrongful dismissal is about inadequate notice, not unfair treatment.

Ontario is an “employment at will” jurisdiction in a limited sense: employers can terminate without cause. What they cannot do is terminate without providing proper compensation for that termination. The amount of compensation you are owed is determined by two separate legal frameworks, and the difference between them is often very significant.

2. ESA Minimums vs. Common Law Notice, The Critical Difference

This is the most important concept in Ontario wrongful dismissal law. Your termination entitlements come from two different sources:

Employment Standards Act (ESA)

  • Statutory minimums set by the Ontario government
  • 1 week of notice per year of service (up to 8 weeks)
  • Severance pay if service ≥5 years AND employer payroll ≥$2.5M: 1 week per year, up to 26 weeks
  • These are the absolute floor. The least an employer can legally give you
  • Most severance offers are based on ESA minimums

Common Law Notice

  • Determined by courts, not by statute
  • Typically 1 month per year of service for many employees
  • Maximum of approximately 24 months for most employees
  • Factors: age, length of service, position, availability of comparable work
  • Almost always higher, often significantly higher, than ESA minimums
The gap between ESA and common law can be enormous. An employee earning $80,000/year with 10 years of service may be entitled to only 8 weeks under the ESA, but up to 18–20 months under common law. That is a difference of approximately $110,000. Most employers offer ESA minimums. Most employees accept without knowing they are owed far more.

3. How Notice Periods Are Calculated in Ontario

Common law notice is not a formula. It is determined by judges based on the specific facts of each case, using what is known as the Bardal factors (from the 1960 Ontario case Bardal v Globe and Mail):

FactorHow It Affects Notice
Length of serviceThe most important factor. Longer service = longer notice. Courts often use roughly 1 month per year as a starting point, though this varies widely.
AgeOlder employees get more notice, because it is harder for them to find comparable work. An employee in their 50s or 60s with long service may receive close to the 24-month maximum.
Position and character of employmentSenior, specialized, or managerial employees typically receive longer notice than entry-level employees with comparable service.
Availability of similar employmentIf comparable jobs in your field are scarce, notice increases. If the market is active and you have transferable skills, notice may be shorter.
Economic conditionsCourts may consider whether a recession or labour market contraction makes reemployment harder.
Special inducementIf you left secure employment to take this job, courts may award additional notice.

4. Just Cause Dismissal, What It Means and How Rare It Is

“Just cause” dismissal, also called termination for cause, means the employer fires you for serious misconduct, and gives you no notice and no severance whatsoever. Just cause is the “capital punishment” of employment law: it is reserved for the most serious misconduct.

What Can Constitute Just Cause

Just cause typically requires serious misconduct, theft, fraud, serious insubordination, harassment, or a fundamental breach of trust. Minor performance issues, personality conflicts, and single instances of poor judgment generally do not constitute just cause. Courts apply a contextual and proportionality test: did the conduct, in all the circumstances, constitute a fundamental breach of the employment relationship?

Employers frequently allege just cause without having it. Many employers use just cause allegations to pressure employees into accepting inadequate settlements, knowing that defending a just cause allegation is expensive and stressful. If your employer claims just cause, speak with an employment lawyer immediately. The bar is much higher than most employers represent.

Progressive Discipline

Ontario courts generally expect employers to have used progressive discipline before dismissing for cause, warnings, performance improvement plans, escalating consequences. An employer who fires an employee “for cause” without having warned them, documented the issues, or given them a chance to improve is unlikely to successfully defend a just cause claim.

5. Constructive Dismissal, When Changes Force You Out

Constructive dismissal occurs when your employer makes a significant unilateral change to a fundamental term of your employment, without your consent, that effectively forces you to resign. The law treats this as if you were fired, entitling you to the same wrongful dismissal notice.

Examples of Constructive Dismissal

ChangeWhy It May Be Constructive Dismissal
Significant salary reduction (10%+)Compensation is a fundamental term. A material reduction without consent is often constructive dismissal.
Demotion or change in title/responsibilitiesA fundamental change to role, reporting structure, or responsibilities can constitute constructive dismissal.
Forced relocation to a different cityRequiring you to work in a different city without contractual right to do so may be constructive dismissal.
Toxic or harassing work environmentIf the employer fails to address serious harassment or poisoned workplace, continued employment may be untenable.
Removal of key responsibilities or authorityGutting your role while keeping you nominally employed is a recognized form of constructive dismissal.
Timing matters critically in constructive dismissal. You cannot work for months under the changed conditions and then claim constructive dismissal, courts may find you accepted the change. If you believe you have been constructively dismissed, you must act promptly. Speak with an employment lawyer before resigning.

6. What to Do Immediately After Being Fired

1

Do not sign anything on the spot

You are almost never required to sign a severance agreement immediately. Take the documents home. You typically have reasonable time, often several weeks, to consider the offer. Ask for the offer in writing if it is not already.

2

Document everything

Note the date and circumstances of your termination. Save all relevant emails, performance reviews, employment contracts, and communications about the termination. This is your evidence base.

3

Speak with an employment lawyer

Before signing anything, have an employment lawyer review your severance offer and your employment contract. Most employment lawyers offer a free initial consultation. The cost of reviewing the offer is almost always less than the additional amount you may be entitled to.

4

Review your employment contract

Your contract may contain a termination clause that limits your entitlements to ESA minimums, or it may not. Many termination clauses are legally unenforceable because they do not comply strictly with the ESA. A lawyer can assess whether yours is valid.

5

Mitigate, start looking for new work

Ontario law requires terminated employees to take reasonable steps to find comparable employment (“mitigation”). Failing to mitigate can reduce your damages. Start looking, document your job search, and keep records of applications and responses.

6

Apply for Employment Insurance (EI)

You are generally entitled to EI benefits after a without-cause termination, regardless of whether you accept a severance package. Apply immediately, there are waiting periods, and delays cost you weeks of benefits.

7. Understanding Your Severance Offer

Severance offers almost always start from the employer’s position, which is usually the ESA minimum. Here is what to look for when reviewing a severance package:

ComponentWhat to Check
Notice/pay in lieu of noticeIs it based on ESA minimums only, or does it reflect common law? Most offers are ESA only.
Benefits continuationDoes the offer continue your health, dental, and life insurance through the notice period? Many do not.
Bonus and commissionsAre you owed any unpaid bonus or commission? These are often omitted from severance offers.
Stock options and equityIf you had unvested options, what happens to them? This can be worth significant amounts.
The release languageWhat rights are you releasing when you sign? Most releases are broad. You give up all claims, including any claim for additional notice.
Confidentiality and non-disparagementAre there clauses restricting what you can say after departure? Non-solicitation clauses restricting clients or employees?
Reference letterHas a positive reference letter been offered? This has real economic value and can be negotiated.
Most severance offers are negotiable. The initial offer is typically a floor, not a ceiling. Employers expect negotiation. Having a lawyer send a demand letter or negotiate directly on your behalf typically results in a higher settlement, often substantially higher than the original offer, while preserving a professional relationship where possible.

8. Frequently Asked Questions

What is wrongful dismissal in Ontario?

Wrongful dismissal in Ontario occurs when an employer terminates an employee without providing proper notice or pay in lieu of notice. It is not about whether the firing was fair. It is about whether the employer gave you enough compensation for the termination. Most employees are entitled to significantly more than ESA minimums under common law.

How much notice am I entitled to in Ontario?

Your entitlement has two levels. The ESA sets out minimums of 1 week per year of service up to a maximum of 8 weeks. Common law notice, set by courts, is typically much higher, often around 1 month per year of service, with a maximum of approximately 24 months for most employees. Age, position, and the availability of comparable work are key variables.

Can I be fired without cause in Ontario?

Yes. Ontario employers can terminate without cause by providing proper notice or pay in lieu. Being fired without cause is not wrongful dismissal. It only becomes wrongful if the employer fails to provide the required compensation. Just cause dismissal (no notice) requires serious misconduct and is hard to establish.

Should I sign my severance agreement right away?

No. Never sign immediately after being fired. Take the offer to an employment lawyer. Most severance offers significantly understate your legal entitlement. Signing releases your right to sue, often for amounts far higher than what was offered. Review first, sign later (or not at all).

What is constructive dismissal?

Constructive dismissal occurs when an employer makes a unilateral and significant change to a fundamental term of your employment, a major pay cut, demotion, relocation, or toxic work environment, without your consent. The law treats this as if you were fired, and you are entitled to the same wrongful dismissal notice. Act promptly. You cannot work under changed conditions indefinitely and then claim constructive dismissal.

Do I need an employment lawyer?

For most terminations, consulting an employment lawyer is one of the highest-ROI decisions you can make. Initial consultations are free at Lexaltico. The additional severance that good legal advice secures typically far exceeds the legal fees involved. You are not obligated to litigate, often a single lawyer’s letter is enough to significantly improve a severance offer.
