Severance Pay in Ontario: What a Calculator Can and Can't Tell You
Ontario severance calculators add up two ESA payments and stop there. How termination pay and severance pay work, the $2.5M test, and what decides the rest.
If you've just been let go in Ontario, there's a good chance the first thing you did was type your salary and years of service into a severance calculator. That's a sensible start, and the number is real, but it's the legal minimum under the Employment Standards Act, 2000 (ESA), not a forecast of what you're owed. Here's what those calculators add up, the test for ESA severance pay, and what no calculator can see, which is usually where the bigger money is.
What does an Ontario severance calculator actually add up?
It's adding up two separate ESA payments, and a lot of people don't realize there are two. The first is termination pay, which every employee with at least three months of continuous service is generally owed when they're let go without cause, unless the employer gave enough working notice instead. The second is severance pay, which only some employees qualify for, and Ontario's ESA guide calls the two "entirely separate" entitlements.
Termination pay scales with how long you've worked there, and it tops out at eight weeks:
- Under 1 year: 1 week
- 1 year but under 3 years: 2 weeks
- 3 years but under 8 years: 1 week for each completed year (so 3 weeks at 3 years, 7 weeks at 7 years)
- 8 years or more: 8 weeks
On top of the weekly pay, you earn vacation pay on your termination pay, and your employer can't stop your benefits during the notice period.
Do you qualify for ESA severance pay?
ESA severance pay is the part with a test, and it's a two-part one. You need five or more years with the employer, and the employer has to either have a global payroll of at least $2.5 million or have severed 50 or more employees within six months because all or part of the business permanently closed. If both parts are met, you're owed one week of regular pay for each year of employment, plus a prorated share for any partial year, up to a cap of 26 weeks.
Severance also counts all your time with that employer, "whether continuous or not and whether active or not," so an earlier stint or time on leave can add to the total. Termination pay doesn't work that way: if two stints are more than 13 weeks apart, only the most recent one counts.
Here's how the two compare:
| Termination pay | Severance pay | |
|---|---|---|
| Who gets it | Most employees with 3+ months of service | 5+ years, at an employer meeting the payroll or closure test |
| How much | 1 to 8 weeks, by length of service | 1 week per year, plus partial years |
| Maximum | 8 weeks | 26 weeks |
To see how they stack, take the government's own severance example: someone earning $1,000 a week with seven years and nine months of service, at an employer that meets the test. Severance pay works out to $7,750 (7.75 weeks), and termination pay for that length of service is seven weeks, or $7,000. Together that's $14,750, plus vacation pay on the termination portion and seven weeks of benefits, and that's the kind of figure a calculator shows you.
Why does the calculator stop at the ESA?
Because the ESA is the only part of the answer that's pure arithmetic. Ontario's own guide says its termination and severance rules "are minimum requirements," and some employees "may have rights under the common law that are greater," which they can pursue by suing for wrongful dismissal.
That common-law amount is called reasonable notice, and it's decided case by case. Steps to Justice, the public legal information site run by Community Legal Education Ontario, notes that most people who are fired or laid off have the right to more than the ESA minimum, especially if they worked there a long time, their job was very specialized, they're older, or a similar job will be hard to find. None of that fits in a calculator's input fields, and a calculator also can't tell you whether you were constructively dismissed, which happens when an employer makes a significant change to a fundamental term, like a big pay cut or a demotion, and you resign over it within a reasonable time.
And if you work for a bank, an airline, a telecom company, or another federally regulated employer, the Ontario ESA doesn't apply to you at all. You're under the Canada Labour Code, so an Ontario calculator is the wrong tool from the start.
Can your contract limit you to the ESA minimum?
It can, if it has a termination clause that holds up, and that's the biggest question a calculator skips. A well-drafted clause can limit you to the ESA minimum, but one that fails gets thrown out, and then you're back to common-law reasonable notice.
Ontario's Court of Appeal has been strict here. In Waksdale v. Swegon North America Inc., 2020 ONCA 391, it held that termination provisions are read as a whole, so if the "for cause" part breaches the ESA, they're all unenforceable, even if the "without cause" part is fine on its own and even if the employer never relied on the bad part. The court applied that rule again in Dufault v. Ignace (Township), 2024 ONCA 915, where it agreed the for-cause clause fell short of the ESA's minimum standards, so the without-cause clause fell with it. The Supreme Court of Canada refused the township leave to appeal on June 5, 2025. And no contract can lawfully give you less than the ESA minimum.
So if you signed an offer letter or contract when you started, dig it out. Whether its termination wording survives this case law isn't something a formula can answer. It's a question for an employment lawyer, and the answer can be worth more than anything a calculator shows.
What changed in late 2025?
Two changes took effect on November 27, 2025, and neither one changes the math above. First, a temporary layoff can now run longer, up to just under 52 weeks in a 78-week window, but only if you agree in writing, you're told the latest recall date, and the Director of Employment Standards approves it. A layoff that runs past what's allowed is treated as a termination, which generally means termination pay. The other change is new job seeking leave: if you get notice of a mass termination, you can take up to three unpaid, job-protected days during the notice period to look for work.
Ministry claim or lawsuit? You have to pick one
Ontario won't let you take both roads for the same termination. You can file an ESA claim with the province's labour ministry, mostly online, generally within two years of the violation. Or you can sue for wrongful dismissal, the only way to recover common-law reasonable notice. The ministry's guide says you "must choose one or the other," and if you file a claim and then decide to go to court, you have to withdraw it within two weeks of filing.
If you sue in Toronto, the size of the claim decides where it's heard. Claims up to $50,000 go to Toronto Small Claims Court at 47 Sheppard Avenue East, and since that limit rose from $35,000 on October 1, 2025, more wrongful-dismissal claims now fit in the simpler court. Larger claims go to the Superior Court of Justice at 330 University Avenue, where cases of $200,000 or less use the streamlined Simplified Procedure. Toronto is also one of three Ontario cities with mandatory mediation for most civil actions, usually within 180 days after the first defence is filed, so a suit here reaches a mediator early. The general limitation period for a lawsuit is two years, and our guide to litigation and dispute resolution in Toronto explains how a case moves through these courts.
If the firing was tied to a protected ground under Ontario's Human Rights Code, such as a disability or your age, there's a separate track at the Human Rights Tribunal of Ontario, with a one-year deadline from the discrimination.
Where to get help in Toronto
Some of that help is free. The province's Employment Standards Information Centre (1-800-531-5551) answers questions about ESA entitlements, and the Workers' Action Centre in Toronto offers free, confidential help at (416) 531-0778 or 1-855-531-0778. For your contract, common-law notice, or a release you've been asked to sign, talk to an employment lawyer before you accept anything, because signing a release usually means giving up the larger claim.
There are 344 employment and labour law firms listed in our Toronto directory as of October 2026, and it's worth shortlisting a few and asking each how they'd read your contract.

Frequently asked questions
Is severance pay the same as termination pay in Ontario?
No, they're two separate payments. Termination pay is owed to most employees with three months of service and runs up to eight weeks, while severance pay is extra and only applies after five years at an employer that meets the $2.5 million payroll test or the closure test.
How much severance do I get after 10 years in Ontario?
Under the ESA alone, 10 years gets you eight weeks of termination pay, plus 10 weeks of severance pay if your employer meets the $2.5 million payroll test or the closure test. That's the statutory minimum. Common-law reasonable notice can be higher, unless an enforceable termination clause in your contract limits you to the ESA minimum.
Are online severance calculators accurate?
They can get the ESA minimum right, because that part's a formula, but they can't estimate common-law reasonable notice or tell you whether your contract's termination clause is enforceable. Treat the result as your starting point, not the answer.
