When a business closes a location, restructures a division, or shuts down entirely, it often needs to terminate many employees at the same time. Ontario employment law treats this differently from a single, one-off dismissal — additional notice obligations and a formal government notification apply on top of the usual rules for individual employees.
If you were part of a larger layoff, understanding how the group rules work — and how they interact with your individual entitlements — helps you know whether you actually received everything you were owed.
What Counts as a Mass or Group Termination
Ontario's employment standards framework has a specific category for terminations that affect a significant number of employees at one establishment within a short window of time. The exact numeric thresholds that trigger this category are set out in the legislation and are worth confirming directly, since figures like this are set by regulation and can move — but the underlying idea is straightforward: when an employer terminates a meaningfully large group at once, the law treats that differently from letting one person go.
If your employer told you that "everyone at this location" or "this whole department" was being let go around the same time, it is worth asking whether the group termination rules applied to your situation.
How Group Termination Notice Differs From Individual Notice
For an individual, no-cause dismissal, Ontario's statutory minimum notice is based on length of service, following a graduated schedule. Group terminations layer additional requirements on top of that individual entitlement — generally, the larger the group being let go at once, the more advance notice the law requires before the terminations can take effect.
This is a separate calculation from an individual employee's own length-of-service notice entitlement — it does not replace it. An employee affected by a group termination is still entitled to at least their own individual statutory notice (or pay in lieu), and potentially more under common law, on top of whatever the group-level rules require.
The Extra Step: Notifying the Government
A distinguishing feature of a group termination is that the employer generally must notify the Ontario government before the terminations take effect, providing information about the affected employees and the circumstances of the termination. This notification requirement does not exist for an individual, one-off dismissal.
If your employer skipped this step in a situation that should have qualified as a group termination, that is worth flagging to an employment lawyer — a failure to follow the correct process can affect what the employer owes.
How This Interacts With Severance Pay
Severance pay in Ontario is a separate, additional entitlement from termination notice, and it does not apply to every dismissed employee. One route to qualifying is having five or more years of service with an employer of a large enough size — but there is also an alternate route specific to mass layoffs: an employee can qualify even where the employer's overall size is smaller, if the employer has severed the employment of 50 or more employees within a six-month period because of a permanent discontinuance of all or part of the business (a figure current as of mid-2026 — verify it before relying on it).
This means a mass layoff connected to a business closing down can trigger severance eligibility for long-service employees who might not otherwise qualify under the general size test alone — worth checking carefully rather than assuming you don't qualify.
Comparing Individual and Group Terminations
| Individual termination | Group/mass termination | |
|---|---|---|
| Notice basis | Employee's own length of service | Additional notice tied to the size of the group being let go, on top of individual notice |
| Government involvement | None required | Employer generally must notify the province in advance |
| Severance pay | Based on the employee's own service and the employer's size | May also be triggered by the size of the layoff itself, even for a smaller employer |
| Employee's own entitlement | Individual statutory notice, possibly more at common law | Still applies, in addition to the group-level rules |
What to Do When a Mass Layoff Is Announced
- [ ] Confirm in writing how many employees were let go, and roughly when, at your location or division
- [ ] Keep your termination letter and any severance package offered
- [ ] Ask whether the employer notified the government of a mass or group termination, if that seems relevant to your situation
- [ ] Do not assume a "standard" severance package template reflects everything you are legally owed
- [ ] Compare notes carefully with coworkers, but remember every employee's entitlement depends on their own length of service and role
- [ ] Get an employment lawyer to review your specific numbers before signing anything
Frequently asked questions
Does a mass termination mean everyone gets the same notice period?
No. The group-level rules add requirements on top of individual entitlements, but each employee's own notice — and any severance — is still calculated based on their individual length of service and circumstances, not one number applied to everyone.
What if my employer says budget doesn't allow for proper notice?
An employer's financial difficulty does not eliminate its legal obligation to provide notice, pay in lieu, or severance where owed. If a business cannot pay everything at once, that is a separate issue from whether the amount is actually owed.
I was part of a layoff of dozens of people — should I still talk to a lawyer even if everyone got the "same" package?
Yes. A standard package offered to a group is often designed to be acceptable on average, not tailored to your individual entitlement, which depends on your years of service, age, position, and other factors. It is common for a review to reveal you are owed more than the general offer.
Does this apply if a business is closing down entirely, not just doing a partial layoff?
The same general framework can apply, and a full closure connected to a large layoff is one of the situations where the alternate severance eligibility test based on the size of the layoff itself becomes especially relevant.
