Transitioning Payroll and Employee Records in an Ontario Business Sale

Somewhere between signing the purchase agreement and the first payday under new ownership, someone has to make sure paycheques actually go out correctly, on time, with the right deductions and the right history behind them. Payroll and employee records are an operational headache if handled poorly — and, in an asset purchase especially, they intersect with real legal obligations under the Employment Standards Act, 2000.

What Usually Needs to Move

Share Purchase vs. Asset Purchase: Different Mechanics

In a share purchase, the employer is the same corporation before and after closing, so payroll and employee records generally continue without a legal break — though the buyer still needs practical access to the systems and files to keep running payroll smoothly.

In an asset purchase, the buyer is a new legal employer. Where the purchaser hires the seller's employees as part of acquiring the business as a going concern, the Employment Standards Act, 2000 generally deems the employment not to have been terminated, carrying prior service over for statutory entitlement purposes — but this continuity depends on the purchaser hiring within a limited window after the sale, and it does not eliminate the practical need to set up new payroll accounts, new tax withholding records, and new personnel files under the buyer's own systems.

Is There a Legal Deadline for the Transition?

There is no single statutory deadline that governs the whole payroll and records transition as a package — the overall timing is a closing-mechanics question the buyer and seller work out between themselves, often tied to the closing date itself so there is no gap in pay. That said, certain related obligations do carry their own separate statutory timelines — source deduction remittances, year-end reporting, and Record of Employment issuance among them — and those should be confirmed directly with your accountant or payroll provider rather than assumed, since getting them wrong carries its own compliance consequences distinct from anything in this article.

A Practical Transition Checklist

• [ ] Confirm which employees are being retained, and from what effective date, in writing
• [ ] Obtain complete personnel files and payroll history for retained employees from the seller as part of closing deliverables
• [ ] Set up (or confirm continuity of) payroll accounts, including source deduction remittance accounts, ahead of the first post-closing pay run
• [ ] Collect current TD1 and any other required tax forms from retained employees if setting up as a new employer
• [ ] Reconcile vacation and leave balances so entitlements are not lost or double-counted in the transition
• [ ] Confirm what happens to group benefits — continuing the seller's plan, enrolling in a new one, or a gap that needs to be bridged
• [ ] Clarify Record of Employment responsibilities with your payroll provider or accountant where employment with the seller is ending as a matter of form
• [ ] Confirm WSIB account status and reporting obligations transfer or are newly established correctly
• [ ] Document any outstanding accommodation, leave, or workplace investigation matters so nothing falls through the cracks

Where This Overlaps With the Purchase Agreement

Purchase agreements for a business sale often specify, as part of the closing deliverables, that the seller provide current employee lists, payroll records, and benefits information to the buyer. If your agreement is silent on this, it is worth raising before closing — chasing down payroll history after the fact, once the seller has moved on, is far harder than building it into the closing checklist.
