Ontario Severance Pay 2026: ESA Minimums, Common Law, and What You're Actually Owed

Ontario's Employment Standards Act, 2000 contains two separate severance provisions, stacked on top of one another, and most Ontario employees who receive a termination package have a reasonable entitlement on top of those as well. The conversation tends to collapse all of this into a single number printed on a PDF. That number is almost never the right one.

What follows is a precise account of how Ontario severance is actually calculated: the statutory floor under ss.57 and 64 of the ESA, the conditions under which those sections apply, the common-law reasonable-notice entitlement that sits above them, and a worked example that puts the whole structure together. If you are an employee trying to assess a package, or an HR lead trying to construct one honestly, the distinction matters significantly.

The Ontario statutory floor: two provisions, not one

Ontario is unusual among Canadian provinces in having a two-part statutory minimum. Most provinces have a single termination-notice or pay-in-lieu obligation. Ontario has that, and a separate severance-pay entitlement that stacks on top when certain thresholds are met. Conflating the two is one of the more common errors in Ontario HR practice.

Section 57: Termination pay. For employees with at least three months of service who are terminated without cause, the employer owes one week of notice (or pay in lieu) per completed year of service, subject to a maximum of eight weeks. An employee with seven completed years is owed seven weeks; an employee with fifteen completed years is still owed eight weeks. This applies to virtually all Ontario employers regardless of size.

Section 64: Severance pay. This is the provision most sources under-explain. It is not a substitute for s.57 — it is an additional entitlement that applies when the employer meets one of two thresholds: (a) the employer's Ontario payroll is $2.5 million or more in the year preceding the termination, or (b) the employer has severed the employment of fifty or more employees within a six-month period (a mass termination). When either threshold is met, the employee is also owed one week of severance pay per completed year of service, capped at twenty-six weeks.

The practical consequence: an employee with twelve completed years of service at a qualifying Ontario employer receives eight weeks under s.57 plus twelve weeks under s.64 — a combined statutory entitlement of twenty weeks. The employer who presents eight weeks as the package is paying less than half of the ESA floor, not the ESA floor.

The $2.5M payroll threshold has been part of the ESA architecture since the original act came into force in 2001, inheriting the logic (though not the precise figure) from the predecessor Employment Standards Act. It is worth noting because it creates a structural asymmetry: a mid-sized Toronto employer qualifies almost automatically, while a 20-person firm in Sudbury with a modest payroll may owe only the s.57 termination pay. Same employee tenure, meaningfully different statutory minimum.

Above the floor: common-law reasonable notice

The ESA provisions are not, and have never been, intended to represent the full measure of what a wrongfully dismissed Ontario employee is owed. They are a compliance floor, enforced by the Ministry of Labour. What sits above them is the common-law doctrine of reasonable notice, anchored in Bardal v. Globe & Mail Ltd., an Ontario High Court decision from 1960 that has been applied in thousands of subsequent cases.

Justice McRuer's formulation in Bardal identified four factors for determining the reasonable notice period: the character of the employment, the length of service, the age of the employee, and the availability of similar employment given the employee's qualifications and experience. Courts since 1960 have refined the weighting without displacing the framework. The practical result is that a senior employee in a specialised role, with a decade or more of service, terminated in a weak labour market, will attract a common-law reasonable notice period that is materially longer than the ESA statutory minimum.

One note on what is sometimes called "Wallace damages" or "aggravated damages" in wrongful dismissal: the 2008 Supreme Court decision in Honda Canada Inc. v. Keays moved away from the earlier Wallace v. United Grain Growers (1997) practice of extending the reasonable notice period for bad-faith conduct in the manner of dismissal. Under the post-Keays framework, damages for bad-faith conduct in the termination process are assessed as compensatory damages rather than as an extension of the notice period. The practical result is roughly similar in egregious cases, but the mechanism is different, and employment lawyers are careful about the distinction.

The role of termination clauses

A common-law reasonable notice entitlement is a default rule. An employment contract can displace it with a clause limiting the employee's entitlement to the ESA minimum — if the clause is validly drafted. Ontario courts have developed an extensive body of case law on when such clauses hold and when they do not.

Clauses that have been struck down include those that failed to explicitly account for both s.57 and s.64, those that could theoretically produce a payment below the ESA floor in some scenario (even one unlikely to arise), and those found to be ambiguous on their face. When a termination clause is invalidated, the employee is treated as though no clause existed and the full common-law entitlement applies. Given how aggressively Ontario courts have policed this area, particularly after Waksdale v. Swegon North America Inc. (2020 ONCA 391), the proportion of employment contracts with enforceable limiting clauses is lower than many HR practitioners assume.

Worked example: twelve years, $80,000, $4M payroll

Consider an employee in Ontario: a project manager, age 47, earning $80,000 annually, with twelve completed years of service, employed by a firm with a $4 million Ontario payroll. The employment contract contains a termination clause. Assume, for now, that the clause is valid.

ESA floor:

• s.57 termination pay: 8 weeks (capped; 12 years would produce 12 weeks but the cap applies)
• s.64 severance pay: 12 weeks (12 completed years at 1 week per year; employer's $4M payroll exceeds the $2.5M threshold)
• Total ESA minimum: 20 weeks, or approximately $30,769 at an $80,000 annual salary

If the termination clause is invalidated:

• Bardal analysis for a 47-year-old project manager with 12 years of service: the role is mid-to-senior, not highly specialised; the labour market for project managers is competitive but not exceptional; age and tenure both pull toward the higher end of the range.
• A reasonable estimate from Ontario employment-law practice: 14 to 18 months of reasonable notice. Call it 16 months as a midpoint.
• At $80,000 annually, 16 months of reasonable notice is approximately $106,667.

The gap between the ESA floor and common-law reasonable notice in this scenario is roughly $75,000. That is the number obscured by a termination package presented as the statutory minimum and a ten-day signature deadline.

What Ontario employees should check before signing

Three items routinely disappear from the termination conversation:

Whether s.64 applies. The employer knows whether its Ontario payroll exceeds $2.5M. The employee may not. If you are unsure, ask, or look at the company's size. A firm with fifty or more Ontario employees almost certainly qualifies.

Whether the termination clause holds. Post-Waksdale, this is not a question with an obvious answer. An employment lawyer can assess the clause in a short consultation. Most offer free or low-cost initial consultations for exactly this reason.

Benefits and bonus continuance. During the statutory notice period, most Ontario employees are entitled to continuation of benefits, not just salary. If the package is structured as a lump sum, it is worth confirming what the employer is treating as included.

The companion post on the Canada-wide picture, Severance Pay in Canada: What You're Actually Owed, covers the Bardal analysis in more depth and provides the statutory comparison across all provinces. The ROE and EI implications of how severance is structured (salary continuance versus lump sum) are addressed in the ROE Canadian SMB Playbook.

For Ontario employers

The ESA floor is not, in most Ontario terminations, the number that survives legal scrutiny. Employers who build termination packages on the assumption that the statutory minimum is adequate for long-service or senior employees are budgeting against a number that a single letter from an employment lawyer will revise upward. The companies that handle terminations well tend to start with a Bardal-range estimate, offer something honest in the first package, and give real time to consider it. That approach costs less than the alternative, most of the time.

The Ontario Severance Pay Calculator on this site computes the ESA floor for any combination of tenure, employer size, and salary in under a minute. It will tell you the s.57 and s.64 figures precisely. What it cannot tell you is whether your contract's termination clause is enforceable, or where a court would land on your Bardal factors. For that, an Ontario employment lawyer is the right tool, and the consultation is almost always worth the hour.
