Large-scale layoffs have been back in the headlines: tech, retail, media, and finance have all seen significant workforce reductions. If you’ve been let go as part of a bigger round of cuts, Ontario’s “mass termination” rules may entitle you to more notice than a standard individual dismissal.

What counts as a mass termination

Under the Employment Standards Act, 2000 (the “ESA”) a mass termination happens when an employer terminates the employment of 50 or more employees at a single establishment within a four-week period. When that threshold is met, the ordinary individual-notice rules are replaced by enhanced group-notice requirements.

The enhanced notice periods

Instead of the usual sliding scale tied to your length of service, mass termination triggers a minimum notice period based on how many people are let go:

  • 50 to 199 employees: at least 8 weeks’ notice or pay in lieu
  • 200 to 499 employees: at least 12 weeks
  • 500 or more employees: at least 16 weeks

These are minimums under the ESA. Your common law entitlement, based on your age, role, and length of service, can be considerably higher, unless a valid contract limits you.

The paperwork requirement

In a mass termination, the employer also has to file a notice with Ontario’s Director of Employment Standards, and the notice period doesn’t formally begin until that filing is complete. Employers don’t always get this right, and a misstep can affect when your entitlements start to run.

Common law still applies on top

It’s a common misconception that the ESA mass-termination figure is the full picture. It isn’t. Those weeks are a floor, not a ceiling. If you don’t have an enforceable termination clause capping you at the minimums, you may be entitled to common law reasonable notice, which for longer-tenured or senior employees is often measured in many months.

What to do if you were part of a group layoff

Group terminations are frequently handled with standardized severance packages offered to everyone at once. That’s efficient for the employer, but a one-size-fits-all package rarely reflects any single individual’s actual entitlement, especially yours if you’re older, senior, or long-serving.

Before you sign a package handed out to a whole department, it’s worth having your specific situation reviewed. Get in touch for a consultation and we’ll help you understand what you’re really owed.
