Reasonable notice in asset sales
When a business is sold, employees always ask the same question: “What happens to my notice and severance?” The answer depends on how the deal is structured and who ends the employment. This guide explains what an asset sale means for reasonable notice of termination in Ontario, and how that differs from a share sale.
TL;DR
In a share sale, the legal employer doesn’t change. Employment usually continues uninterrupted and a sale, by itself, doesn’t trigger notice.
In an asset sale, the seller’s employment relationships generally end at closing. If the buyer hires an employee, that’s a new employment relationship.
Under Ontario’s Employment Standards Act (ESA), if the buyer hires the employee within the statutory window, the employee’s service is “deemed continuous” for ESA purposes (notice, severance, vacation, leaves).
At common law, courts do not automatically glue the seller years to the buyer years. Instead, they assess reasonable notice using the usual factors, and may credit the employee’s prior “experience” with the seller when the buyer later dismisses them.
Offers of comparable employment from the buyer are often relevant to the employee’s duty to mitigate and can reduce damages against the seller.
First principles: share sale vs. asset sale
Share sale: The corporation (employer) is the same legal entity before and after closing. Employees usually carry on as normal. If major post-sale changes occur (e.g., drastic demotion), that can raise separate constructive-dismissal issues—but the sale itself doesn’t end the job.
Asset sale: The buyer purchases the business assets, not the employer’s shares. Employment with the seller typically ends at closing. The buyer may offer new employment—often effective the next day—sometimes on modified terms.
ESA continuity vs. common-law notice: two different systems
ESA continuity (minimum standards)
If a buyer hires the employee within the statutory window after an asset sale, the ESA treats the employee’s service as continuous. Practically, that means the buyer must count seller service when calculating ESA entitlements (termination pay, severance pay where applicable, vacation, and most leaves).
There is a time gap rule: a short break between the seller and buyer jobs can still count as continuous under the ESA, but a longer break can break continuity. (The ESA sets specific timing thresholds.)
Common-law reasonable notice (beyond the minimums)
Common-law notice is different. After an asset sale:
The employee’s job with the seller ends. Any common-law claim against the seller is based on seller service only, and is subject to mitigation (see below).
If the buyer later dismisses the employee, courts do not simply add the seller years to buyer years. Instead, they apply the usual Bardal factors (age, position, length of service, and availability of similar employment) and may weigh the employee’s prior “experience” gained with the seller—especially if the buyer hired them to do substantially similar work. In other words: prior service can influence the notice period, but there’s no automatic “continuous service” at common law.
Who owes what and when?
1) Claims against the seller (vendor)
If employment ends at closing and the employee doesn’t move over, the seller typically owes ESA termination (and severance if applicable) and, absent an enforceable termination clause, common-law reasonable notice based on service up to closing.
If the buyer offers comparable employment and the employee refuses, courts often treat the refusal as a failure to mitigate, reducing the seller-side damages.
If the employee accepts the buyer’s offer and continues working without a gap, the seller-side damages may be limited or fully mitigated, depending on the circumstances and any closing payment or release.
2) Claims against the buyer (purchaser)
The buyer is a new employer. If it later terminates without cause, common-law notice is assessed afresh. Prior experience with the seller can increase the notice period, but courts don’t automatically total the years.
If the buyer recognizes prior service “for all purposes” in its offer letter, that can increase exposure on termination (both ESA and potentially common law). If it recognizes service for ESA only, the common-law effect will depend on the wording and overall circumstances.
Releases, “bridging” letters, and closing mechanics
Releases at closing typically protect the seller, not the buyer. An employee who releases the seller can still make a wrongful-dismissal claim against the buyer if the buyer later terminates them. A payment received at closing may still be relevant to the overall notice analysis against the buyer.
Bridging service: Buyers sometimes agree to recognize seller service for ESA only—or “for all purposes.” Be precise. Sloppy language can unexpectedly enlarge common-law exposure.
New contracts: Because the buyer is a new employer, it can offer a fresh agreement with updated terms (subject to ESA compliance and enforceability rules). Clear, lawful termination provisions reduce later disputes.
Mitigation: do employees have to accept the buyer’s offer?
Often, yes—if the offer is reasonably comparable (role, pay, location, seniority, culture). Employees have a duty to mitigate their losses. Refusing a reasonable buyer job can shrink or eliminate damages against the seller. The analysis is fact-specific: short-term “labour only” roles, significant pay cuts, relocations, or toxic settings may change the result.
Practical guidance
For employees
Get the offer in writing and check whether prior service is recognized (ESA only vs. all purposes), whether there’s a probationary period, and what the termination clause says.
Don’t assume your seller years automatically carry over at common law. They may still matter as “experience,” but the math isn’t automatic.
Mitigation matters. If the buyer’s offer is reasonably comparable, refusing it can reduce your claim against the seller.
Keep your documents: closing letters, any release, the buyer’s offer, handbooks, and benefits summaries.
For employers (sellers and buyers)
Plan people early in the deal: who’s moving, who isn’t, and what the letters say.
Use precise bridging language. If you intend ESA-only recognition, say so clearly; if you agree to “all purposes,” price the risk.
Right-size the buyer offer: role, pay, and seniority should be consistent with expectations; consider whether prior service will be recognized and how that will be framed.
Coordinate releases: seller releases should be properly explained and timed; don’t assume a seller release shields the buyer.
Audit termination clauses: post-hire disputes often turn on enforceability. Keep clauses ESA-compliant and current.
FAQs
Does an asset sale automatically end my job?
With the seller, usually yes. If the buyer hires you right away, your ESA service may be deemed continuous; your common-law rights are assessed under the usual factors, not by automatically adding years.
If the buyer fires me later, do I get credit for my seller years?
Not automatically. Courts may give weight to your prior experience with the seller when setting notice, but they don’t simply stitch the two periods together.
What if I refuse the buyer’s offer?
If the job is reasonably comparable, refusal can reduce damages against the seller because of the duty to mitigate.
What changes in a share sale?
Nothing fundamental: the employer is the same corporation, so employment usually continues and no notice is triggered by the sale alone.
Bottom line
In an asset sale, ESA service can be continuous, but common-law notice isn’t a straight line from Day 1 with the seller. Instead, courts weigh the employee’s experience and all the circumstances. Careful closing documents—and clear, lawful buyer offers—make the difference between a smooth transition and a costly dispute.
