Fired With Cause vs. Without Cause: Why the Difference Matters
Employers say cause far more often than the law allows. The distinction decides whether you get severance at all, so it is worth understanding exactly where the line sits.
Key takeaways
- Without cause: your employer can end your job for almost any reason, but must give you notice or pay in lieu (severance).
- With cause: the employer alleges serious misconduct and offers nothing. It is the harshest outcome in employment law and very hard to prove.
- Employers allege cause far more often than the law allows. If the claim fails, you are owed your full severance.
- There are actually two standards: common law just cause, and the even higher ESA "wilful misconduct" bar you must cross to lose your statutory minimums.
- Never accept a "for cause" termination at face value. Have it reviewed before you walk away with nothing.

Whether you were fired "with cause" or "without cause" decides whether you walk away with a severance package or with nothing. That is why it matters so much, and why employers reach for "cause" more often than they are entitled to. The good news for employees is that true just cause is one of the hardest things for an employer to actually prove.
✅Quick answer. A without cause dismissal means your employer ended your job for an ordinary reason (restructuring, fit, performance) and must pay you notice or severance. A with cause dismissal means the employer alleges misconduct so serious it justifies firing you with nothing. Just cause is a very high bar, often called the "capital punishment" of employment law, and employers frequently allege it without the evidence to back it up. If the cause claim does not hold up, you are owed full severance.
What is the difference between with cause and without cause?
| Without cause | With cause | |
|---|---|---|
| What the employer is saying | We are ending your job (ordinary reason) | You committed serious misconduct |
| Do you get severance? | Yes, notice or pay in lieu | The employer says no |
| How hard is it to justify? | No justification needed | Very hard to prove |
| How often is it valid? | Almost always | Often overstated or wrong |
What actually counts as just cause?
Just cause requires serious misconduct that strikes at the heart of the employment relationship. Courts do not treat it as a checklist; they look at the full context. Conduct that can rise to just cause includes:
- Theft, fraud, or serious dishonesty.
- Violence, threats, or serious harassment.
- Serious and repeated insubordination after clear warnings.
- A serious conflict of interest or competing against your employer.
- Gross or repeated incompetence after the employer has warned you and given a real chance to improve.
Even then, context controls. In McKinley v. BC Tel (2001), the Supreme Court held that dishonesty justifies dismissal only when it is serious enough to be incompatible with continued employment. A proportionality analysis applies: the punishment of dismissal-for-nothing has to fit the misconduct.
Why just cause is so hard for an employer to prove
Because the consequence is so severe (no notice, no severance), courts set the bar high and put the burden on the employer. A single mistake, poor performance without warnings, or a personality conflict almost never qualifies. "Near cause" is not a thing in Ontario: an employer cannot reduce your severance just because your conduct was less than perfect. It is all or nothing, and the employer has to clear a high evidentiary bar to get the "nothing" outcome.
How high the bar sits shows up in the results. Even serious-sounding allegations regularly fail:
- Walter v. Birks Group Inc. (2024 ONSC 3626): the employer alleged theft of five watch straps worth about 2,500 dollars and pointed to a prior discipline record. The court found no just cause and no wilful misconduct, and awarded the long-service employee 24 months of pay.
- Ratz-Cheung v. BMO Nesbitt Burns Inc. (2024 ONSC 2499): the bank alleged a breach of its code of conduct; the cause claim failed and the employee was awarded 24 months.
- Williamson v. Brandt Tractor Inc. (2025 ONSC 2571): a cumulative record of sales-conduct complaints did not add up to just cause, and the employee recovered 17 months of notice.
If cause fails, what are you owed?
A failed cause allegation turns your dismissal into a without-cause one, with full notice owed. Estimate that range with our free, case-law-calibrated calculator.
Cause does succeed when the misconduct is deliberate and strikes at trust. In Abbasbayli v. Fiera Foods Company (2025 ONSC 3240), an employee who swiped a co-worker's timecard to fake his hours and then lied in the investigation met both the common law and the higher ESA standard. In Park v. Costco Wholesale Canada Ltd. (2023 ONSC 1013), an employee who deliberately deleted a company website twice and made misleading statements about it also lost on both tests. The pattern is clear: dishonesty and deliberate acts that break trust can be cause; ordinary mistakes and thin allegations are not.
The two standards: just cause vs. ESA wilful misconduct
This is the nuance most people miss. There are two different tests, and an employer has to meet an even higher one to take away your statutory minimums:
- Common law just cause lets the employer avoid paying common law reasonable notice.
- ESA "wilful misconduct" (Regulation 288/01) is a higher bar that the employer must meet to deny you even the ESA minimum termination and severance pay. It requires conduct that is deliberate and "not trivial," essentially being bad on purpose, not just careless or mistaken.
The practical result: an employer can sometimes establish common law just cause and still owe you your ESA minimums, because wilful misconduct is harder to prove. Many "for cause" terminations fail one or both tests.
⚠️Employers over-allege cause. A "for cause" letter is a legal position, not a proven fact. Do not treat it as the final word, and do not sign anything admitting misconduct. If the cause does not hold up, your full severance is back on the table.
What should you do if your employer alleges cause?
- 1.Do not sign anything that admits wrongdoing or accepts the characterization of events.
- 2.Ask for the allegation in writing, including the specific facts the employer is relying on.
- 3.Keep your own records: emails, reviews, warnings (or the absence of them), and your version of events.
- 4.Do not resign, which can undercut your position. Let the dismissal stand as the employer's decision.
- 5.Get it reviewed quickly. The review is free, and a weak cause claim often converts into full severance.
If the cause claim fails, your entitlement is the same as any without-cause dismissal. See how that number is built in our guide to severance pay in Ontario and what a wrongful dismissal claim looks like, or get a free review of your situation.
Frequently asked questions
Can my employer fire me for cause for poor performance?
Rarely. Ordinary poor performance is not just cause, especially without clear warnings and a real chance to improve. Just cause for incompetence requires serious or repeated failure after the employer has put you on notice. Most performance-based firings are without cause, which means you are owed severance.
What is the difference between with cause and without cause?
Without cause means you were let go for an ordinary reason and are owed notice or severance. With cause means the employer alleges serious misconduct and offers nothing. With cause is very hard to prove and is often overstated.
Do I get any severance if I am fired for cause?
If genuine just cause is proven, you may get nothing. But the bar is high, and to deny your ESA minimums the employer must prove the even higher standard of wilful misconduct. Many cause claims fail one or both tests, which brings your severance back.
Should I sign a termination letter that says I was fired for cause?
Do not sign anything admitting misconduct or accepting the employer's version of events. A for-cause letter is a position, not a proven fact. Get it reviewed before responding.
What is wilful misconduct under the ESA?
It is a higher standard than common law just cause, requiring deliberate, non-trivial misconduct (being bad on purpose, not just careless). An employer must meet it to deny you even the statutory minimum termination and severance pay.
