Employment liability does not stay with the seller by default. In most of Canada, an employee who keeps working for the buyer brings their whole service history with them — and that changes what the buyer actually owes if things go wrong.
Key takeaways
STEP 01 OF 10
Most private Canadian businesses fall under provincial employment standards, but a federally regulated business — banking, telecommunications, interprovincial transportation — falls under the Canada Labour Code instead, with its own continuity rule. Confirm this before running the rest of the checklist, since the rules genuinely differ rather than converging on one national standard.
STEP 02 OF 10
Ontario’s continuity provisions apply where the business “is sold or transferred in any other way to a new owner” and the employee “continues to work in the business for the new owner” — the effect, per the regulator’s own guide, is that the seller’s length of employment “is attributed, or ‘flows through’ to the purchaser… they do not start as a ‘new employee’ but instead get ‘credit’ for their past employment,” illustrated with an employee with 10 years at the seller, terminated one year after the transfer, entitled to eight weeks' notice rather than just one.
The statutory notice ladder that follows from this runs 1 week under one year of service, up to 8 weeks at 8 years or more, with special mass-termination rules where 50 or more employees are terminated at one establishment within a four-week period.
STEP 03 OF 10
Ontario severance pay is a distinct, additional obligation on top of notice, and it has its own two-part eligibility test: the employee needs five or more years of service, and either a global payroll of at least $2.5 million or the severance of 50 or more employees within a six-month period tied to a business closure. The maximum severance payable under the ESA is 26 weeks. The trap for a diligence team: “global payroll” means global — a target that looks sub-scale on its own can trip this threshold once its parent’s worldwide payroll is counted.
STEP 04 OF 10
Ontario has banned employee non-competes since October 25, 2021, with narrow exceptions. The sale-of-business exception applies only where there is a sale or lease of a business or part of a business operated as a sole proprietorship or a partnership, the seller becomes an employee of the purchaser immediately following the sale, and the purchaser and seller enter into the non-compete as part of the sale — as written, this names a sole proprietorship or partnership, not a corporation, so it does not obviously reach the ordinary Ontario deal shape of a share sale of a corporation where the vendor stays on. A separate executive-only exception exists for named C-suite roles. Do not assume a non-compete is enforceable on a typical share sale merely because the seller stays on as an employee — confirm with counsel which exception, if any, actually applies.
STEP 05 OF 10
BC’s Employment Standards Act is broader on this point than Ontario’s. Section 97 states that “if all or part of a business is disposed of, or the business continues to operate under a receiver or receiver-manager, the employment of an employee of the business is deemed… to be continuous and uninterrupted by the disposition or receivership”. Note what this adds beyond Ontario: continuity survives a receivership, which matters directly for the distressed-acquisition scenario where a buyer might otherwise assume employment obligations reset entirely on insolvency.
STEP 06 OF 10
Canada Labour Code s. 189 deems employment continuous “despite the lease or transfer… from one employer to another employer by sale, merger or otherwise,” and extends to a retendered contract under s. 189(1.1) — but s. 189(1.2) cuts this off if the employee’s first day with the new employer is more than 13 weeks after the earlier of their last day with the first employer and the transfer date. A gap in employment longer than that window breaks continuity, which a buyer negotiating a delayed start date for retained staff should factor into the timeline.
STEP 07 OF 10
Pull length of service, current compensation and benefits, and existing written employment agreements for every employee who is expected to continue — this is the raw data every later step in this guide depends on. See building and controlling a data room for how this folder should be organized and cross-referenced against the rest of the disclosure.
STEP 08 OF 10
Once the census is built, run the Ontario ladder (or the applicable provincial equivalent) across every continuing employee to estimate the buyer's aggregate exposure if the workforce were terminated the day after closing. This is a diligence exercise, not a plan to terminate anyone — but a buyer who has not run this number has not actually priced the employment risk they are assuming.
STEP 09 OF 10
An asset purchase can, in principle, let a buyer choose which employees to hire fresh rather than inheriting continuity — but doing so deliberately to avoid the continuity rules is exactly the fact pattern these provisions are written to catch, and provincial regulators read the substance of what happened, not the label the parties gave it. A share purchase gives the buyer no such choice at all: the corporation and its full employment history transfer intact, which is one more reason a co-owner buyout (always a share purchase) carries the full inherited employment history by default.
STEP 10 OF 10
Treadstonelaw’s split of legal versus financial diligence puts employee records and employment agreements squarely on the legal side, reviewed by the lawyer rather than the accountant — and its separate note on inherited liabilities in a share purchase names unpaid wages, vacation pay, exposure tied to how past terminations were handled, and the corporation's workplace-safety claims history as categories a buyer inherits regardless of disclosure. Confirm the folder actually answers each of these, not just the census.
Take a concrete case: an employee with 6 years and 4 months of service at the seller, who continues working for the buyer and is then terminated 8 months after closing — 7 years and 0 months of total combined service. Under the Ontario ladder, 7 years falls in the “7” band, entitling the employee to 7 weeks’ notice, computed on the buyer’s payroll even though most of that tenure was served under the seller.
If the same corporation's global payroll (parent included) exceeds $2.5 million and this employee has crossed 5 years, the severance-pay test in Step 3 is also satisfied — severance = weekly wage × (completed years + completed months ÷ 12) = weekly wage × (7 + 0÷12) = weekly wage × 7, on top of the notice already owed. Both obligations are real and separate; a diligence team that computes only one has understated the exposure.
Both provinces attribute service history to the buyer, but they differ on what triggers it and how automatically it applies. Ontario's continuity provision requires the employee to actually continue working for the new owner — it is conditional on that continued employment happening. BC's s. 97 is broader in scope: it applies to a disposition “or the business continues to operate under a receiver or receiver-manager,” explicitly reaching a receivership scenario without requiring the same active continuation language.
A buyer assuming the two provinces work identically risks under-pricing employment exposure in a BC distressed acquisition specifically, where continuity may apply even through an insolvency process that an Ontario-trained diligence team might assume resets employment obligations.
No — continuity governs what happens to length-of-service credit if an employee continues working for the buyer; it does not compel the buyer to retain anyone. What it changes is the notice and severance calculation if a continuing employee is later terminated.
Generally no, as between the employer and the employee — employment standards legislation sets minimum entitlements that cannot be contracted below. The purchase agreement can allocate financial responsibility for pre-closing liabilities between buyer and seller as between themselves, which is a separate question from what the employee is owed.
The employment continuity mechanics are the same regardless of who the buyer is — see buying out a partner in an existing company for how that transaction interacts with these same rules.
This guide does not state a Quebec-specific rule — Quebec's civil-law employment regime differs from the common-law provinces covered here, and no primary source for it was available to verify. Confirm Quebec continuity rules separately before relying on any analogy to Ontario or BC.
Many agreements do exactly that through an indemnity, but the indemnity is a promise between buyer and seller — it does not change what the employee is legally owed by whichever entity employs them after closing. Treat the indemnity as recourse against the seller, not as a substitute for pricing the exposure correctly at diligence.
