Licences, WSIB and transfers in a trades sale

Trade licences are generally held by individuals, not the company, so a trades sale must confirm who will hold them after closing, obtain a current WSIB clearance certificate, and transfer vehicle registration and any liens before the deal closes.

Reviewed

A trades business sale in Canada does not simply hand its licences, WSIB standing and vehicle registrations to the buyer along with the keys. Trade certifications are generally held by individuals, not the company, workers' compensation clearance has to be re-confirmed close to closing, and vehicles and equipment often need their registration and any liens dealt with directly. Sorting out what actually transfers, what has to be reapplied for, and who needs to hold what, belongs early in a deal, not the week before closing.

Trade certifications belong to a person, not the company

Trade certifications, such as a licensed electrician’s, plumber’s or gas technician’s qualification, are issued to a person who has completed the required training, examinations and, in many trades, a period of supervised experience. A corporation cannot itself hold that certification; it needs a certified individual working within it who is legally allowed to do or supervise the regulated work. That means a sale has to answer a specific question early: is the buyer personally certified in the trade, and if not, is there an employee staying on who is, or does the buyer have a credible plan to bring in someone qualified before closing. A deal that assumes this will simply sort itself out after closing is taking on real regulatory risk.

Business-level registrations, on top of personal certification

Depending on the trade and the province, there may also be a separate registration or licence tied to the business itself, on top of the individual’s certification — for instance a contractor licence issued by a municipality, or a specialty registration for gas or refrigeration work. These obligations sit alongside, not instead of, the personal trade certification, and both generally need to be confirmed as part of a sale rather than assumed to carry over automatically with the change in ownership.

WSIB clearance in a trades sale

A WSIB clearance certificate is a standard piece of an Ontario trades sale. It confirms the business is registered with the Workplace Safety and Insurance Board and current on its premiums, and it protects the party who relies on it — generally both the buyer and the general contractors the business works for — from being held liable for unpaid amounts tied to the seller's history. Because clearance is tied to a point in time, both sides typically want a fresh certificate close to closing rather than relying on one pulled weeks earlier. Outside Ontario, the same underlying idea applies through each province's own workers' compensation board, though the certificate's name, process and requirements differ, so a buyer operating across provincial lines needs to check the specific board's process rather than assume Ontario's rules apply everywhere.

Transferring vehicle and equipment registration

Vehicles and equipment carry their own transfer mechanics. Commercial vehicles need their ownership and registration updated with the relevant provincial authority, and any liens registered against a vehicle or piece of equipment need to be paid out or otherwise addressed before the asset can transfer free and clear. Buyers financing the fleet as collateral for their own loan should expect their lender to run its own lien search rather than take the seller’s word that equipment is unencumbered.

Employment continuity and deal structure

Employment continuity is the other piece that gets tangled up with licensing in a trades sale, because crew retention often depends on how the transaction is structured. In an asset sale, employment technically ends with the seller and begins fresh with the buyer, which raises questions under provincial employment standards about recognizing prior service, and in a share sale, employment generally continues without interruption because the employer — the corporation — has not changed. Which structure applies, and what it means for vacation entitlement, notice periods and benefits continuity, is a real question for a lawyer to work through on both sides, not something to leave to assumption.

Apprentices and unionized crews

Apprentices working toward their own certification add another layer worth checking. An apprentice is typically registered against a specific sponsoring employer and journeyperson, and a change in ownership can affect that registration depending on how the deal is structured and whether the sponsoring journeyperson stays with the business. A buyer inheriting apprentices partway through their training should confirm what needs to be updated with the relevant training authority so those employees are not left in limbo. Where a crew is unionized, which is more common on the commercial and industrial side of trades than on residential-focused shops, a collective agreement can also affect whether it survives a change of ownership at all, and that question turns heavily on deal structure and needs its own legal review rather than a general answer.

A licensing and transfer checklist

A trades sale with licensing and transfer items handled well generally has, in place well before closing:

  • Confirmation of who will personally hold each required trade certification after closing
  • A plan for any separate municipal, contractor or specialty registrations the business needs
  • A current WSIB clearance certificate dated close to the closing date
  • Vehicle and equipment title, registration and lien searches completed
  • Clarity, with legal advice, on how the deal structure affects employee continuity
