Understanding how severance pay works in Ontario matters most at the worst possible moment — the day you lose your job, often with a package in front of you and a deadline to sign it. The single most valuable thing to know is that “severance” is not one number but a stack of separate entitlements, and the amount an employer offers first is frequently the statutory floor, not what you may actually be owed.

This guide untangles the whole picture: the two payments the Employment Standards Act guarantees, the much larger common-law entitlement that sits alongside them, what triggers each, and the decisions — especially around signing — that determine how much you walk away with.

The two ESA payments

The Employment Standards Act sets a legal minimum made of two distinct parts. Termination pay compensates you for notice your employer should have given: one week per year of service, capped at 8 weeks, owed to almost anyone employed three months or more. Your employer can deliver it as working notice, as a lump sum in lieu, or a combination. Severance pay is a separate entitlement — one week per year up to 26 weeks — but it only applies if you have five or more years of service and your employer has a payroll of $2.5 million or severed 50+ employees in six months.

The distinction is not academic. A worker with three years at a small firm gets termination pay only. A worker with fifteen years at a large corporation gets both, stacked — up to 8 weeks of termination pay plus 15 weeks of severance, all calculated on their regular weekly wage. Our severance pay calculator works out the combined total, and the notice periods table shows the weeks for every length of service.

Common law: the bigger, hidden entitlement

Here is what employers rarely volunteer: for most non-unionized employees, the ESA minimum is not the limit of what they can claim. Ontario common law entitles a dismissed employee to reasonable notice, and courts routinely set this far above the statutory floor. Where the ESA caps termination at 8 weeks, common-law reasonable notice can run to many months — occasionally beyond a year and a half for a long-service senior employee.

Courts decide reasonable notice case by case, weighing four main factors, known informally as the Bardal factors: your age, your length of service, the character of your employment (senior and specialized roles attract more), and the availability of similar work. An older employee in a senior role who will struggle to find a comparable job can be awarded notice measured in many months, dwarfing the ESA number. The catch: common-law notice is not paid automatically and cannot be claimed through the free government process. It requires a civil claim, and in practice an employment lawyer.

Which route: the free claim or a lawyer

This is the fork that decides how much you receive. The free Ministry of Labour claim recovers the ESA minimum — no cost, no lawyer, an officer does the work, and you must file within two years. It is the right tool when the amount owed is the statutory minimum and your employer simply hasn’t paid it.

A lawyer and a civil claim are the route to common-law notice, and they make sense whenever your likely reasonable-notice entitlement is materially larger than the ESA figure — which is common for long-service, senior or older workers. You generally cannot pursue both for the same dismissal, so the choice matters. Most employment lawyers offer a free initial consultation, and many work on contingency, so establishing whether your case is worth more than the statutory minimum usually costs nothing. The practical rule: if your ESA number feels small next to a long career or a senior role, get a legal opinion before you accept anything.

Constructive dismissal and other traps

You do not have to be formally fired to be entitled to severance. Under the ESA and at common law, a constructive dismissal — where an employer makes a fundamental unilateral change to your job, such as a significant pay cut, demotion, or forced relocation — can count as a termination if you resign in response within a reasonable time. So can a temporary layoff that runs longer than the ESA permits. If your employer has changed the deal substantially, you may have been dismissed in law even though nobody used the word.

Two groups get nothing: employees dismissed for wilful misconduct that is serious and not condoned, and those employed less than three months. And one clause can cap your entitlement in advance: a valid termination clause in your employment contract can limit you to the ESA minimum and remove the common-law upside — but such clauses are frequently drafted incorrectly and struck down by courts, which is another reason a legal review before signing anything is worthwhile.

Before you sign anything

Severance packages usually come with a release — a document that, once signed, waives your right to claim anything further. Employers often present it with a deadline to create urgency. You are entitled to take reasonable time to review an offer, and signing is close to irreversible, so the review is where money is won or lost. A lawyer can tell you in one consultation whether the offer reflects your common-law entitlement or just the ESA floor.

Finally, run your EI claim in parallel. Apply within four weeks of your last day regardless of any severance negotiation — a severance payment may delay when EI starts, because Service Canada can allocate it across the following weeks, but it does not reduce your total EI, and waiting to apply can cost you benefits outright.
