The ordered path from "I might sell" to a signed deal and a clean handover.
Who this is for: Ontario business owners thinking about selling — whether to a competitor, an employee, a family member, or an outside buyer. What you'll get: the sale process broken into ordered phases, a timeline table, and a printable checklist so you know what comes next and what to prepare.

How to read this roadmap
Selling a business is a sequence, not a single event. Each phase below builds on the last. The biggest mistake owners make is starting too late — the preparation you do months ahead is what gets you a clean sale at a fair price. Work the phases in order, and use the "you're done when…" line to know it's time to move on.
Timeline at a glance
Timing varies a lot with the size and complexity of the business. Treat these as rough orders of magnitude, not promises.
| Phase | What happens | Typical timing* |
|---|---|---|
| 1. Prepare | Clean up records, get a valuation, assemble advisors | Months ahead |
| 2. Confidentiality | Sign NDAs before sharing anything sensitive | Before any disclosure |
| 3. Letter of Intent | Agree the framework: price, structure, exclusivity | A few weeks |
| 4. Due diligence | Buyer reviews your documents | Several weeks to months |
| 5. Purchase agreement | Negotiate and sign the binding deal | A few weeks |
| 6. Tax planning | Structure the sale for the best tax result | Runs alongside 3–5 |
| 7. Employees | Plan communications and transitions | Before/at closing |
| 8. Closing & transition | Money changes hands; you hand over | Closing day + a transition period |
*Confirm timing with your own advisors — every deal is different.
Phase 1 — Prepare (start here, ideally well before you list)
What happens: You get the business ready to be sold and to withstand scrutiny.
Who does it: You, with your accountant and lawyer.
What you need to do:
- Clean up the minute book. Make sure your corporate records — resolutions, share register, by-laws — are complete and up to date. A messy minute book scares buyers and delays closings.
- Clean up the financials. Get statements and tax filings current and consistent. Remove personal expenses that are run through the business so the real earnings are visible.
- Get a valuation. An accountant or business valuator gives you a defensible asking price, instead of a number you hope for.
- Assemble your advisors. A lawyer, an accountant, and possibly a business broker. Bring them in early — pre-sale advice shapes the whole deal.
- Fix obvious problems. Resolve outstanding disputes, sort out who owns the IP, and tidy up customer and supplier contracts.
💡 Why preparation pays: Buyers pay more for a business that's organized, transparent, and low-risk. Every hour spent cleaning up now reduces the price chipped away during due diligence later.
✅ You're done with this phase when: your records and financials are clean, you have a credible valuation, and your advisory team is in place.
Phase 2 — Confidentiality (protect yourself before you share)
What happens: Before you hand a prospective buyer any sensitive information, they sign a non-disclosure agreement (NDA) — a contract promising to keep what they learn confidential and not to use it against you.
Who does it: Your lawyer drafts or reviews the NDA; you and the buyer sign.
What you need: an NDA tailored to a business sale, ideally with a non-solicitation clause so a "buyer" can't quietly poach your staff or customers.
⚠️ Watch out: Competitors sometimes pose as buyers to learn your numbers, your customers, and your margins. Never share financials, customer lists, or trade secrets until an NDA is signed — and even then, release information in stages.
✅ You're done with this phase when: every serious prospect has signed an NDA before receiving anything sensitive.
Phase 3 — The Letter of Intent (set the framework)
What happens: Once a buyer is serious, you sign a Letter of Intent (LOI) — a short document outlining the proposed price, deal structure (asset or share), and key terms. Most of it is non-binding, but the confidentiality and exclusivity clauses usually are.
Who does it: Negotiated between you and the buyer; your lawyer reviews before you sign.
What you need: clarity on price, structure, what's included, exclusivity period, and the conditions to closing.
💡 Why it matters: The LOI sets the tone and the anchors for everything that follows. Exclusivity means you agree not to shop the business to others for a set period — fair, but don't grant a long one without a committed buyer.
✅ You're done with this phase when: both sides sign an LOI you understand and your lawyer has reviewed.
Phase 4 — Due diligence (the buyer does their homework)
What happens: The buyer requests and reviews your documents — corporate records, financials, contracts, employees, IP, litigation, permits, and assets — to confirm the business is what you've described.
Who does it: You and your team assemble and disclose; the buyer and their advisors review.
What you need: an organized data room (a shared, secure folder of documents) and prompt, honest answers.
⚠️ Watch out: Disclose fully. Hiding a problem that surfaces later can collapse the deal — or expose you to a claim for breach of your representations. Surprises kill deals; disclosed issues get negotiated.
✅ You're done with this phase when: the buyer has reviewed your materials and remains committed (or you've renegotiated terms based on what they found).
Phase 5 — Negotiating the purchase agreement (the binding deal)
What happens: Lawyers draft and negotiate the definitive Asset Purchase Agreement or Share Purchase Agreement — the binding contract.
Who does it: Your lawyer drafts/negotiates with the buyer's lawyer; you give instructions on the business terms.
Key terms to negotiate:
| Term | What it means for you |
|---|---|
| Asset vs. share | Drives your tax outcome and which liabilities go with the buyer |
| Purchase price | The headline number — plus how and when it's paid |
| Holdback / earnout | Part of the price held back or tied to future performance; you want the holdback small and short |
| Representations & warranties | Your promises that the facts are true; keep them accurate and reasonably limited |
| Indemnities | Your agreement to cover the buyer for certain problems; negotiate caps and time limits |
| Non-compete | Your promise not to compete; must be reasonable in scope, area, and time to be enforceable |
| Conditions to closing | What must happen before money moves (financing, consents, approvals) |
💡 Why it matters: A seller's biggest exposure usually isn't the price — it's the representations, warranties, and indemnities. They can leave you on the hook after closing. A good lawyer limits them to what's fair and caps your liability.
✅ You're done with this phase when: a signed agreement is in place, with conditions to closing clearly set out.
Phase 6 — Tax planning (do this alongside Phases 3–5, not after)
What happens: You and your accountant structure the sale to keep more of the proceeds.
Who does it: Your accountant leads, with your lawyer on the legal structure.
Why it can't wait: The Lifetime Capital Gains Exemption (LCGE) can shelter a portion of the capital gain on the sale of qualifying small-business corporation shares from tax. But qualifying depends on conditions about the company and your shareholdings — some of which must be met before the sale, and some well in advance. Decisions made early (or missed) can cost or save a great deal.
💡 Don't leave money on the table: The LCGE generally applies to share sales of qualifying corporations, not asset sales — another reason structure and tax planning go hand in hand. The exemption amount and the qualifying rules change; treat any figure you've heard as "as of writing" and confirm the current amount and conditions with the CRA or your accountant. See our tax guides for a fuller walkthrough, and get advice early.
✅ You're done with this phase when: your accountant has confirmed the most tax-efficient structure that's achievable for your situation, and you've structured the deal accordingly.
Phase 7 — Employees (plan the people side)
What happens: You decide what to tell staff, and when, and how their employment carries over.
Who does it: You, with HR and legal input; coordinated with the buyer.
What to plan for:
- In a share sale, employment usually continues unchanged — the employer (the corporation) is the same.
- In an asset sale, employees are technically terminated by you and offered new jobs by the buyer, which can trigger termination/severance obligations under Ontario's Employment Standards Act, 2000 and common law.
- Timing of the announcement matters — too early can cause staff to leave; too late can feel like a betrayal. Coordinate with the buyer.
⚠️ Watch out: Accrued vacation, severance exposure, and key-employee retention are real costs that affect the deal. Address them in the agreement — don't leave them to be sorted out after closing.
✅ You're done with this phase when: the employee plan is agreed with the buyer and any related obligations are reflected in the deal.
Phase 8 — Closing and transition (handing over the keys)
What happens: On closing day, signed documents and the purchase price are exchanged, and ownership transfers. Then you typically help the buyer take over for a transition period.
Who does it: The lawyers manage closing; you support the transition.
What you need: all signed agreements, transfer documents, consents, releases of any liens (PPSA), and the funds flow.
Transition often includes:
- A handover period where you train the buyer and introduce key relationships.
- Honouring the non-compete you agreed to.
- Final adjustments (working capital, inventory counts) settled shortly after closing.
✅ You're done with this phase when: the deal has closed, funds are received, the transition period is complete, and your post-closing obligations are met.

Mini-FAQ
How long does the whole sale take? It varies widely — confirm with your advisors. From serious preparation to closing, many small-business sales run several months to a year or more.
Should I use a broker? Often helpful for finding buyers and marketing the business — but a broker is not a substitute for a lawyer and accountant on structure, tax, and the agreement.
Can I sell to an employee or family member instead? Yes, and many owners do. The same phases apply, though valuation, financing, and tax planning often need extra care.
