Mass Layoffs in Ontario: How Much Notice Are You Owed in 2026?
Ontario’s mass-termination rules can require substantially more statutory notice than the ordinary individual notice schedule. The rules generally apply when an employer terminates 50 or more employees at an establishment within the same four-week period.
These are rules for termination of employment, not simply any temporary layoff. Whether a layoff has become a termination is a separate ESA question.
What Counts as an Employer’s “Establishment” in Ontario?
An establishment is generally a location where the employer carries on business. Separate locations are treated as one establishment if they are in the same municipality or if specified contractual seniority or bumping rights connect them.
For mass-termination purposes, the definition was expanded in 2023 to include an employee’s private residence where the employee works from home and does not work at any other location where the employer carries on business. This can cause remote-only employees working from homes in the same municipality as an employer location to be counted with that establishment.
A hybrid employee who also works at an employer location is generally connected to that workplace rather than having the home treated as a separate establishment for this rule.
When Does the 50-Employee Rule Apply in Ontario?
The employer must terminate at least 50 employees at the establishment within the same four-week period. There is a limited 10% exception if the number of terminated employees is not more than 10% of the employees who have been employed at the establishment for at least three months and none of the terminations was caused by the permanent discontinuance of all or part of the business at the establishment. Both conditions must be met.
Employees with less than three months of service can still count when determining how many employees were terminated for purposes of the threshold. However, the ESA’s notice entitlement generally applies only to employees with at least three months of continuous employment.
How Much Notice Is Required in a Mass Termination in Ontario?
Where the mass-termination rules apply, the statutory notice period depends on the number of employees terminated at the establishment, not each employee’s individual years of service:
50 to 199 employees: 8 weeks of notice.
200 to 499 employees: 12 weeks of notice.
500 or more employees: 16 weeks of notice.
An employer may provide working notice, termination pay instead of notice, or a combination permitted by the ESA. During a working-notice period, the employer must continue to comply with the ESA’s wage and benefit requirements.
Form 1 and Other Employer Obligations in Ontario
A mass-termination notice is not effective until the Director of Employment Standards receives the prescribed Form 1. On the first day of the notice period, the employer must also post the Form 1 in the workplace where affected employees will see it and provide a copy to each affected employee.
Since July 1, 2025, an employer initiating a mass termination must also provide affected employees with the Ministry’s Employment Ontario Career Supports information sheet on the first day of the notice period.
Since November 27, 2025, an employee who has received mass-termination notice may also be entitled to up to three unpaid, job-protected days during the notice period for job-search activities such as interviews, training and networking. The ESA contains an exception where the employee receives very little working notice and the balance as termination pay.
Could You Be Owed More Than the Mass-Termination Minimum in Ontario?
Yes. The 8-, 12- and 16-week periods are minimum ESA notice requirements. They do not necessarily determine the full value of a termination package.
Depending on the employment agreement, an employee may be entitled to common-law reasonable notice that materially exceeds the ESA minimum. Benefits, bonuses, commissions and other compensation may also form part of the claim.
Statutory severance pay is separate. It applies only where the employee and employer meet the ESA’s eligibility requirements; participation in a mass termination does not automatically create a severance-pay entitlement.

FAQs: Mass Lay-offs in Ontario
Generally, at least 50 employees must be terminated at an establishment within the same four-week period. The definition of establishment and the limited 10% exception can change the result.
The ESA minimum is 8 weeks for 50 to 199 terminations, 12 weeks for 200 to 499, and 16 weeks for 500 or more. A greater contractual or common-law entitlement may still apply.
They can. For mass-termination purposes, a private residence can count as an establishment where the employee works from home and does not work at another employer location. The municipal-location rules and the employee’s connection to a physical workplace must then be considered.
No. ESA severance pay has separate service and employer-size or permanent-closure requirements. Mass-termination notice and statutory severance pay must be analyzed separately.
Since November 27, 2025, qualifying employees who receive mass-termination notice may take up to three unpaid, job-protected days during the notice period for job-search activities, subject to the ESA’s conditions and exceptions.
