Employment obligations when a business changes hands

Employees are rarely the first thing a buyer and seller negotiate in a Canadian business sale, and they are almost always among the most consequential. What a change of ownership actually does to an employment relationship, whether it continues without interruption, gets legally terminated and re-offered, or triggers obligations neither party fully anticipated, depends heavily on how the deal is structured and on which province’s employment standards legislation applies, and the two structures do not treat this the same way at all.

Why the structure of the deal matters here too

In a share sale, the employer, the corporation itself, does not legally change. Employees continue working for the same legal entity under a new set of shareholders, and their employment relationship, service dates, and entitlements generally carry through without a formal break. An asset sale is a different mechanism entirely: the purchasing entity is a different legal person from the one that employed the staff, which means employment with the old employer technically ends and, if the buyer offers continued work, a new employment relationship begins with the new entity. Whether that new relationship recognizes the employee’s prior service, and what obligations attach if it does not, is governed by each province’s own employment standards legislation, not by a single national rule, and provinces differ meaningfully in how they treat continuity of service across a change of employer.

What tends to differ by province

• Whether provincial employment standards legislation deems continuous employment to carry forward on an asset sale, and under what conditions, which affects notice, severance, and length-of-service calculations for staff kept on by a buyer
• What notice or pay obligations arise if a buyer chooses not to offer continued employment to some or all staff, and how those obligations are shared or allocated between outgoing and incoming employer
• Whether a collective agreement, where the workforce is unionized, survives a change of ownership automatically or requires a separate process, which can differ depending on the applicable labour relations legislation
• How each province treats accrued vacation pay, benefits, and other entitlements that were building up under the previous employer at the moment ownership changes

Why this is worth confirming before, not after, an offer is signed

A buyer who assumes employment simply carries over, or a seller who assumes staff are automatically the buyer's problem the moment the deal closes, can both be wrong in ways that only become expensive after the fact. Getting this right generally means confirming, specific to the province the business operates in and the structure the deal is taking, what each side's obligations actually are, ideally with input from employment counsel rather than assuming a pattern from one province or one prior deal applies everywhere. It is also worth checking a business's standing with its provincial workers' compensation regulator before closing, since some provinces attach successor-employer obligations around unpaid premiums to whoever takes over an operation, regardless of how the deal itself is structured.

What both sides can do before closing

A practical step available to both sides is confirming, in writing and specific to the province involved, exactly what continuity of service will mean for staff who move across to a new employer, rather than leaving it as an assumption each side interprets differently. Buyers financing an acquisition also do well to ask their lender directly whether assumed payroll and benefit obligations were factored into how the loan was underwritten, since a mismatch discovered after closing is a considerably worse position than raising it during due diligence. Sellers, for their part, are often better served telling long-serving staff the truth about what a change in structure will mean for their accrued entitlements as early as confidentiality reasonably allows, rather than letting rumour fill the gap, since an anxious workforce is itself a risk a buyer’s advisors are likely to notice on any site visit conducted before closing.

What this means for how staff are told

Because the legal mechanics differ so much by structure and province, how and when employees are told about a pending sale is worth planning deliberately rather than improvising once a deal is close to signing. A seller who has already confirmed what the applicable provincial rules require, and what the buyer intends to offer existing staff, can generally have a more honest and less anxiety-inducing conversation with employees than one who is still working that out after the news has already leaked internally, which it very often does well before either party planned to announce it.
