№ 01.2The Deal, End to End

Six steps, from offer to ownership

The same sequence underlies almost every owner-run London & Southwestern Ontario deal — what changes from deal to deal is how long each step takes.

Reaching an agreement

01

Offer or letter of intent

Buyer and seller agree on price and key terms, usually informally, before lawyers draft anything binding. We review before you sign — even a "non-binding" LOI can lock in terms you didn't mean to fix.

usually 1–2 weeks
02

Agreement of purchase & sale

The APS sets out price, structure (asset or share), conditions, and closing date. We draft or review it and negotiate the protections — reps, warranties, holdbacks — that actually matter for your deal.

1–3 weeks to negotiate
03

Due diligence & searches

Corporate, PPSA lien, litigation, and licence searches confirm what you're actually buying. We chase the seller's lawyer, the registries, and any regulator whose sign-off your deal needs.

2–4 weeks, in parallel

Getting to closing

04

Financing & third-party consents

Landlord, franchisor, lender, and licensing-body sign-offs are chased in parallel with the paperwork. In this region it's often a college's Certificate of Authorization or an OEM supply-contract consent that sets the pace, more than the landlord.

often the critical path
05

Closing day

Funds, keys, and signed documents change hands. We coordinate directly with both sides' lawyers and the lender so nothing is left to a last-minute phone call.

1 day, once conditions are met
06

After closing

Registrations, licence transfers still in progress, and any post-closing deliverables — like a holdback release — get tracked to completion, not left for you to chase.

1–2 week tail
Most owner-run London & Southwestern Ontario deals close in 30–60 daysLarger or fleet/franchise deals typically run longer.
№ 01.3Deal Structure

Asset purchase or share purchase?

This is the first real decision in almost every deal — and it changes what you're buying, what you're taking on, and how it's taxed.

QuestionAsset purchaseShare purchase
What you buyThe business's assets — equipment, inventory, lease, goodwill, name.The shares of the company itself — everything it owns, and everything it owes.
Seller's liabilitiesGenerally stay behind with the seller's corporation.Generally come with the company, known and unknown.

Tax angle — buyerA stepped-up cost base on assets bought; an HST s.167 election may apply.Cost base carries over from the seller — a different position for the buyer.
Licences & contractsMust generally be re-issued or assigned into the buyer's name.Usually stay in place, since the corporation itself doesn't change.

№ 01.4Due Diligence, Both Sides

What gets checked before closing

Different lists depending on which side of the deal you're on — both matter for how smoothly closing goes.

If you're buying

  • Financial statements & normalized earnings
  • PPSA / lien searches
  • Litigation & execution searches
  • CRA / HST account status
  • WSIB clearance certificate
  • Licence & permit standing
  • The lease, assignment terms & landlord consent
  • Key contracts & change-of-control clauses
  • Employees & ESA obligations
  • College Certificate of Authorization & associate agreements, for dental and medical practice purchases
  • Phase I environmental screening, for manufacturing purchases on older industrial sites
What we do: run the searches, chase the certificates, and flag anything that changes your price or your conditions.

If you're selling

  • Clean books & tax filings current
  • Contract assignability audit
  • Licence standing confirmations
  • Equipment lien payouts
  • Staff plan for closing day
  • Lease estoppel / landlord early contact
  • Patient-record transfer plan (PHIPA), for practice sales
  • Associate non-solicitation terms reviewed before you list
What we do: tell you what a buyer's lawyer will ask for — before they ask for it.

№ 01.8Before You Ask

London & Southwestern Ontario closing questions

I'm a dentist buying a London practice from a retiring dentist — why is this almost always a share sale?

Ontario's dental college generally requires voting shares of a professional corporation to be held by licensed dentists, and it doesn't permit holding-company ownership of a dental PC — which pushes most practice sales toward a share structure rather than an asset sale. A new or updated Certificate of Authorization from the college is a standard closing condition. We coordinate the college approval alongside the purchase agreement so neither holds up the other.

Does Sarnia's petrochemical-corridor location add extra diligence to a manufacturing purchase?

It can — a manufacturing site with a long industrial history in that corridor sometimes warrants a Phase I environmental site assessment before you commit, particularly if real property is included in the deal. Not every manufacturing purchase needs this, but it's worth checking early rather than discovering it during financing. We flag when a Phase I makes sense for your specific site.

What happens to my restaurant's AGCO licence when I buy it in London?

A liquor licence generally needs to be transferred or newly applied for through AGCO when a restaurant changes hands — it doesn't move automatically with the sale. The health unit typically also wants to inspect before you reopen under new ownership. We track both processes so your opening date isn't held hostage to paperwork.

How long does a dental or medical practice sale usually take to close?

Practice sales usually run longer than a typical restaurant or retail deal — often several months rather than a few weeks — mainly because of the college approval and Certificate of Authorization timeline. Associate agreements and patient-record transfer terms also take time to negotiate properly. We build your closing date around the college's realistic timeline, not an optimistic one.

I'm selling my retail store in Woodstock — what will a buyer's lawyer ask for first?

Expect early requests for your lease and any assignment terms, a clean set of financial statements, and confirmation that your key supplier accounts and any licences are in good standing. Buyers' lawyers also typically want to see how inventory will be counted and valued at closing. We tell you what to have ready before the request even comes in.
