Selling a Business in Ontario: What Happens to Employees, Who Owes Notice, and How to Protect Your Rights
When a business is sold in Ontario, employees frequently have urgent questions about whether their jobs are secure, whether their length of service carries over, and what they are owed. The answers depend primarily on the structure of the transaction and what happens to employees at closing. Ontario's Employment Standards Act, 2000 contains specific continuity provisions that protect employees in most asset sale scenarios but the common law picture is more complex, and the risks for both sides are significant without proper legal advice before the transaction closes.
Were you offered new employment terms after a business sale in Ontario that reset your service or limited your notice rights?
A new employment agreement signed at closing can extinguish your continuity rights and your common law entitlement. Get advice before you sign anything especially any document that waives claims arising from the transition.

Share sale employer does not change
In a share sale, the purchaser acquires the shares of the corporation that owns the business. The corporation remains the legal employer. Employees continue working for the same legal entity with no change to their employment status, their length of service, or their entitlements. No termination is triggered and no notice or severance is owed solely because ownership of the shares changed hands.
For employees, share sales are generally straightforward your employment relationship continues unchanged and all accrued entitlements are preserved. The employment contract that existed before the sale remains in place.
Asset sale continuity rules become critical
In an asset sale, the purchaser acquires business assets rather than the corporation itself. The seller and purchaser are different legal employers. Employees of the seller may be terminated at closing and offered new employment by the purchaser. At common law, this can constitute a termination of employment but Ontario's Employment Standards Act, 2000 Section 9 requires the purchaser to recognize prior service for statutory purposes where the employee continues working.
The gap between what the ESA requires and what common law may provide and the risk of an employee signing away rights in a new agreement is where most disputes arise.
Section 9 ESA continuity what it means in Ontario
Section 9 of Ontario's Employment Standards Act, 2000 provides that where a business is sold and an employee of the seller continues working for the purchaser, their employment is deemed continuous for the purposes of the ESA. The purchaser must recognize the employee's prior service with the seller for all length-of-service-based ESA calculations.
| What Section 9 continuity affects | Result for the employee |
|---|---|
| ESA termination notice | Prior service with the seller counts the purchaser cannot treat the employee as a new hire for notice calculations |
| Statutory severance pay | Prior service counts toward the five-year threshold and the severance pay calculation subject to the employer payroll requirement |
| Vacation entitlements | Accrued vacation entitlements carry over and must be recognized by the purchaser |
| Other length-of-service rights | All ESA entitlements based on length of service are calculated using combined service with the seller and purchaser |
ESA notice and statutory severance on a business sale
Under Ontario's Employment Standards Act, 2000, termination notice is based on total length of service one week per year up to a maximum of eight weeks. Where Section 9 continuity applies, prior service with the seller is included. Statutory severance pay up to 26 weeks applies where the employee has at least five years of service and either the employer's Ontario payroll is $2.5 million or more, or the termination is part of a mass termination. Again, where Section 9 applies, prior service counts toward the five-year threshold.
These ESA minimums are the floor, not the ceiling. Where no valid termination clause limits the employee's entitlement, common law reasonable notice applies calculated on age, total length of service, position, compensation, and the availability of comparable work. For senior or long-service employees, common law notice can significantly exceed the ESA maximum.
What employees and employers should do when a business sale is pending
If you are an employee in an Ontario business sale
- Do not sign any new employment agreement offered by the purchaser without legal advice new agreements at closing frequently contain terms that reset your service, cap future notice at ESA minimums, or include releases that waive claims arising from the transition
- Continuing to work for the purchaser without signing a new agreement generally preserves your Section 9 continuity rights and does not extinguish your common law entitlements
- Where you are terminated at closing rather than offered continued employment, ensure the termination pay reflects your full service period including time with the seller under Section 9
- Where material changes to your employment terms are presented as a condition of continuing with the purchaser reduced pay, altered role, changed benefits get advice on whether those changes constitute a constructive dismissal
If you are an employer or purchaser in an Ontario business sale
- Assess termination notice and severance exposure based on employees' combined service with the seller and purchaser Section 9 prevents purchasers from treating continuing employees as new hires for ESA purposes
- Allocate termination liabilities clearly in the purchase agreement determine in advance who bears the liability for any employee terminated at closing or within a defined period after
- Draft new employment offers carefully offers that preserve continuity while containing valid, ESA-compliant termination clauses require precise drafting to be effective
- Be alert to the risk of inadvertent constructive dismissal material changes to employment terms offered to continuing employees may trigger claims even where no formal termination occurred
- Get legal advice before the transaction closes post-closing surprises on severance liability are among the most common and costly employment law issues in Ontario business sales

Are employees automatically terminated when a business is sold in Ontario?
Not automatically. In a share sale, the legal employer does not change and employment continues unaffected. In an asset sale, employees may be technically terminated by the seller at closing and offered new employment by the purchaser. Where they continue working, Section 9 of Ontario's Employment Standards Act, 2000 deems employment to be continuous for ESA purposes the purchaser cannot treat them as new hires. Whether the common law also treats employment as continuous depends on the specific facts of the transaction and the terms of any new agreement.
Does my length of service carry over when a business is sold in Ontario?
For ESA purposes, yes Section 9 of Ontario's Employment Standards Act, 2000 requires the purchaser to recognize prior service with the seller where the employee continues working after the sale. This applies to termination notice, statutory severance, vacation entitlements, and all other length-of-service-based ESA rights. At common law, prior service may also be credited in a reasonable notice calculation where employment was seamless, the role was substantially unchanged, and the new agreement recognized prior service.
Can I be required to sign a new employment agreement when a business is sold in Ontario?
A purchaser can offer a new employment agreement as a condition of continued employment. However, signing without legal advice carries real risk. New agreements presented at closing frequently contain terms that reset service, cap future notice at ESA minimums, or include releases that waive claims arising from the transition. Continuing to work without signing generally preserves your Section 9 continuity rights and does not on its own extinguish your common law entitlements. Get legal advice before signing any document connected to a business sale transition.
Am I entitled to statutory severance pay when a business is sold in Ontario?
Potentially yes, where the eligibility conditions are met. Statutory severance under Ontario's Employment Standards Act, 2000 requires at least five years of service with Section 9 continuity, prior service with the seller counts and either an employer payroll of $2.5 million or more in Ontario, or that the termination is part of a mass termination. Where both conditions are met, severance pay of one week per year of service up to a maximum of 26 weeks applies. This is separate from and in addition to termination notice.
What if I am not offered continued employment when the business is sold in Ontario?
Where you are terminated at closing rather than offered continued employment, you are entitled to ESA termination notice based on total service including any prior service recognized under Section 9 and statutory severance where applicable. Where no valid termination clause limits your entitlement, common law reasonable notice applies and may significantly exceed the ESA maximum. If the compensation offered does not reflect your full entitlement, you may have a wrongful dismissal claim. Get legal advice before accepting any offer or signing a release.
