Selling Your Business in Ontario: A Step-by-Step Roadmap

The ordered path from 'I might sell' to a signed deal and a clean handover.

Last reviewed 2026-06

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.

⚖️ This is a general guide, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.


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.

PhaseWhat happensTypical timing*

2. ConfidentialitySign NDAs before sharing anything sensitiveBefore any disclosure
3. Letter of IntentAgree the framework: price, structure, exclusivityA few weeks
4. Due diligenceBuyer reviews your documentsSeveral weeks to months
5. Purchase agreementNegotiate and sign the binding dealA few weeks
6. Tax planningStructure the sale for the best tax resultRuns alongside 3–5
7. EmployeesPlan communications and transitionsBefore/at closing
8. Closing & transitionMoney changes hands; you hand overClosing 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:

💡 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:

TermWhat it means for you
Asset vs. shareDrives your tax outcome and which liabilities go with the buyer
Purchase priceThe headline number — plus how and when it's paid
Holdback / earnoutPart of the price held back or tied to future performance; you want the holdback small and short
Representations & warrantiesYour promises that the facts are true; keep them accurate and reasonably limited
IndemnitiesYour agreement to cover the buyer for certain problems; negotiate caps and time limits
Non-competeYour promise not to compete; must be reasonable in scope, area, and time to be enforceable
Conditions to closingWhat 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:

⚠️ 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:

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.
