- Every question about employees in a business sale traces back to one thing: is the legal employer changing?
- Because the employing corporation does not change in a share sale, employees generally notice nothing different about their legal employment status on closing day.
- The buyer acquires specific assets — equipment, contracts, goodwill, sometimes real property — not the seller's corporate existence.
If you are buying or selling a business in Ontario, one of the first questions employees ask — and one of the first things a lawyer flags — is what happens to their jobs. The answer depends almost entirely on whether the deal is structured as an asset sale or a share sale, because the two structures treat the employment relationship in fundamentally different ways.
In one structure, nothing about the legal employment relationship changes at all. In the other, the buyer starts from a blank page and decides, employee by employee, who it wants to keep. Getting this distinction backwards is one of the more common — and more expensive — mistakes in a business sale.
This article walks through what actually happens to a workforce under each structure, and where the Employment Standards Act, 2000 fits in.
The Core Question: Does the Employer Actually Change?
Every question about employees in a business sale traces back to one thing: is the legal employer changing?
- In a share sale, no. The corporation that employs the staff is the same corporation before and after closing — only its shareholders change.
- In an asset sale, yes. The buyer is a different legal entity from the seller, and employment with the seller does not automatically become employment with the buyer.
Share Sales: Employment Continues Without a Ripple
Because the employing corporation does not change in a share sale, employees generally notice nothing different about their legal employment status on closing day. Their existing employment contracts, accrued service, and entitlements simply continue with the same employer — there is no "transfer" to think about, because nothing about the employer has moved.
This is also why the Employment Standards Act, 2000's continuity-of-employment rules are not really engaged in a pure share sale — those rules exist to bridge a change in employer, and a share sale does not involve one.
Asset Sales: The Buyer Chooses Who to Hire
An asset sale is different. The buyer acquires specific assets — equipment, contracts, goodwill, sometimes real property — not the seller's corporate existence. That means:
- The buyer has no automatic obligation to hire any of the seller's employees.
- Employees whose jobs the buyer wants to continue are typically offered new employment by the buyer, effective on or after closing.
- Employees the buyer does not retain remain employees of the seller, whose employment ends with the seller — raising its own termination and severance questions.
Where the ESA Steps In: Continuity of Employment
Section 9 of the Employment Standards Act, 2000 softens the "blank page" effect of an asset sale in an important way. Where a business (or part of one) is sold as a going concern and the purchaser hires the seller's employees to keep it running, the ESA generally deems those employees' employment not to have been terminated — meaning their prior service with the seller counts toward statutory entitlements, such as vacation and notice, as though they had always worked for the buyer.
That continuity has a limit. It generally does not apply if the purchaser hires the employee more than 13 weeks after the earlier of the employee's last day with the seller or the date of the sale. Miss that window, and the statutory bridge is not available.
It is also worth being clear about what this rule does not do. It is a statutory-minimum concept — it does not mean the buyer automatically inherits the seller's exposure to a common-law reasonable-notice claim, which is a separate and often larger risk assessed on its own facts.
Comparing the Two Structures
| Question | Share sale | Asset sale |
|---|---|---|
| Does the employer change? | No | Yes |
| Is the buyer obligated to hire anyone? | N/A — employment is unaffected | No, hiring is discretionary |
| Does prior service automatically count? | Yes, automatically | Only if ESA continuity applies |
| Do employment contracts carry over? | Yes, unchanged | Not automatically — buyer usually issues new terms |
| Common-law notice risk for the buyer | Inherited with the corporation | A separate, fact-specific question |
Frequently asked questions
If I'm selling my business as an asset deal, am I responsible for employees the buyer doesn't hire?
Generally, yes — if the buyer does not offer employment to an employee, that person's employment with you, the seller, is the one that is ending, which can trigger termination-related obligations on your side. This is a significant planning issue for sellers and worth reviewing well before closing.
Can the buyer just keep the old employment contracts in place?
It can choose to, but it is not required to, and it is more common for a buyer in an asset deal to issue fresh employment agreements rather than adopt the seller's old paperwork. What terms those new agreements contain, and how they treat prior service, is a separate negotiation.
Does it matter if employees don't realize whether it's a share sale or an asset sale?
Legally, yes, even though a share sale can feel invisible to employees day-to-day. The structure determines their legal rights, so both buyer and seller should be precise about it in any communication to staff.
What about unionized employees?
A unionized workforce raises additional, separate legal questions about whether a collective agreement and union certification follow the business — questions that do not track the asset-versus-share line the same way ESA continuity does. That is a distinct area requiring its own review.
