Combining payroll, bookkeeping and administration across several newly acquired sites is one of the first moves a roll-up sponsor makes, and it is usually pitched purely as cost saved. Some of what looks like a saving is really a liability that used to be invisible because it sat inside a business too small to trigger it — and consolidation is exactly what makes it visible.
Key takeaways
Combining payroll, bookkeeping and administration across several newly acquired sites is usually one of the first moves a roll-up sponsor makes, and it is almost always pitched purely as cost taken out of the combined administration. Some of what looks like a saving is really a liability that used to be invisible, because it sat inside a business too small on its own to trigger it — and consolidation is exactly the step that makes that liability visible for the first time.
Ontario's continuity-of-employment rule attributes an employee's length of service with the seller onto the purchaser wherever the employee continues working in the business after a sale. The guide's own worked example is direct: an employee with ten years at the seller, terminated one year after the transfer, “will be entitled to eight weeks’ notice rather than just one week”. A back-office consolidation that eliminates a redundant role at an acquired site is pricing that termination on the employee's full combined tenure, not on however many months have passed since closing — and notice runs on a scale from one week under a year of service up to eight weeks at eight years or more, with special mass-termination rules where 50 or more employees at one establishment lose their jobs within a four-week period. British Columbia's version is automatic rather than conditional on the employee being kept on, and expressly survives a disposition of all or part of a business or a receivership — a meaningfully wider rule than Ontario's.
Ontario severance pay, on top of statutory notice, applies where an employee has five or more years of service and the employer either has a global payroll of at least $2.5 million, or severed 50 or more employees within six months because all or part of the business permanently closed. “Global payroll” means global — an acquired site whose own standalone payroll never approached $2.5 million can find itself covered the moment its payroll is measured together with the rest of the platform, which is precisely the measurement a back-office consolidation creates by definition. The maximum severance payable under the ESA is 26 weeks, calculated as regular weekly wages multiplied by completed years plus completed months divided by 12.
The Competition Act's criminal wage-fixing and no-poach offence applies to an agreement between an employer and “another employer who is not affiliated” with that person, to fix, maintain, decrease or control salaries, wages or terms and conditions of employment, or to not solicit or hire each other’s employees — punishable, on indictment, by up to 14 years' imprisonment or a fine in the court's discretion. The offence is built specifically around non-affiliated employers, which is why coordinating pay bands and hiring across a group's own, commonly owned sites is a different question in principle from an arrangement with an outside competitor. But affiliation under the Act is a defined, control-based test, not a label a sponsor gets to assume — and where the group also coordinates with a still-separate business, such as during a transition period before an add-on formally closes, confirming affiliation before assuming the internal exemption applies is worth a competition lawyer's time, not an assumption made in the back office.
Books and records of account, together with the vouchers needed to verify them, have to be retained until six years from the end of the last taxation year to which they relate, in an electronically readable format if kept electronically — a federal obligation that does not disappear when three sites' bookkeeping moves onto one shared platform. Consolidating the systems changes who is responsible for meeting that retention obligation going forward; it does not shorten or reset the six-year clock already running on records from before the acquisition.
A sponsor consolidates bookkeeping and payroll across three acquired trades businesses into one shared-services entity one year after the last of the three closed. One site's original bookkeeper, whose role is now redundant, is let go as part of the consolidation. That bookkeeper had six years of service with the original owner before the sale and one year since, for seven years of combined service — entitled under Ontario's continuity rule to seven weeks' statutory notice, not the roughly one week a business would owe a true one-year hire. Separately, none of the three sites individually had a payroll near $2.5 million, but the combined shared-services entity's payroll now does — so a different employee elsewhere in the group, with seven years of service, now also qualifies for ESA severance pay on top of notice, an obligation that did not exist for that employee's role before the three payrolls were combined.
No. Ontario's continuity-of-employment rule attributes the employee's length of service with the seller onto the purchaser, so notice and severance entitlements are calculated on the full combined tenure, not the time since the acquisition closed. British Columbia's equivalent is automatic and applies even through a receivership.
Yes. Ontario's severance-pay test is triggered at a $2.5 million global payroll — a threshold measured across the whole employer, not per site. Sites that never approached that figure individually can cross it the moment their payrolls are combined.
The criminal wage-fixing and no-poach offence applies specifically to agreements with another employer that is not affiliated with the accused. Whether commonly owned sites count as affiliated is a defined, control-based test under the Act — worth confirming rather than assuming, particularly where coordination extends to a still-separate, unacquired business.
