Does a collective agreement automatically transfer when I buy a unionized business in Ontario?

Hiring nobody defeats ESA continuity, not this test

ESA s.9(1) continuity requires “the purchaser employs an employee of the seller”; a buyer that hires nobody is correct that it has no exposure under that section. Section 69 asks a different question — whether a business, defined broadly to include “a part or parts thereof,” was sold, leased, transferred, or otherwise disposed of — and it is answered by looking at continuity of operations: customer accounts, routes, schedules and equipment, not at who was put on payroll. Section 69(13) then puts an affirmative duty on the buyer and seller to “adduce at the hearing all facts within their knowledge that are material” to the allegation, which means the integration memos and pricing models a buyer wrote for its own purposes become the evidence against it.

Merging workforces after closing can trigger the same power from the buyer’s own decision

Section 69(6) engages where a buyer “intermingles the employees” of the acquired business with its own, unrelated, existing workforce. Intermingling does not by itself end the inherited agreement — it opens a Board application that can run either way: releasing the buyer from the agreement, or declaring one union across the newly merged unit, reaching employees who were never previously organised at all. A narrower, time-limited exception exists under s.69(5), but only on an application within 60 days and only where the purchaser’s business has “changed its character so that it is substantially different from” the seller’s — a comparison against the seller’s business, not the buyer’s merged operation.

Where this played out — Case Files

The hiring-nobody distinction decided the routes were bought but none of the drivers. The intermingling power is the subject of intermingled crews and a bargaining unit redrawn. The narrow, time-limited exception decided sixty days to say the business had changed character.
