Selling a business in Ontario comes down to five things:
- Get your financial, corporate, and business records in order, early.
- Choose between a share sale and an asset sale, with tax advice.
- Expect the buyer to dig deep into your business (due diligence) and prepare for it.
- Negotiate the price, the promises you make, and how you'll get paid.
- Line up every approval you need, and plan the closing and what happens after.
Buyers pay less, or walk away, when they find surprises. Sellers who start early, get good tax and legal advice, and treat the sale like a real project, not a last-minute scramble, tend to do best.
- Start organizing your financial, corporate, and business records well before you plan to sell.
- An asset sale and a share sale work very differently. Compare them based on old debts, required approvals, and what you want out of the deal.
- Get tax advice before you sign a letter of intent, the first written outline of a deal. It keeps your options open.
- Expect buyers to dig deep into your business. Fix major problems before you go to market.
- Find out early which contracts, leases, licences, or lenders need to approve the sale.
- Negotiate carefully the promises you make (representations), your protections against claims (indemnities), and how long those protections last.
- Decide how you'll get paid: cash now, a deposit, an earnout tied to future results, or seller financing.
- Match any promise not to compete or poach staff to what the deal actually needs, no more.
- Plan the closing day and what comes after it: paperwork, money, filings, and follow-up duties.
Getting Your Business Ready to Sell
Buyers pay more for a business that's organized and easy to hand over. That means clear financial statements, contracts that are written down and up to date, business and personal money kept separate, tidy corporate records, and a business that can run without you standing over it. Before you put your business on the market, look for anything a buyer might find and question: loans to or from the owner, unpaid taxes, lawsuits, privacy issues, or missing licences. If only you know how the business really works, a buyer may offer less, ask for a longer handover, or walk away.
A manufacturing client came to us about a year before they planned to sell. In that time, we worked with their accountant to separate personal spending from the company's books, put every major supplier and customer relationship into a signed contract, and helped the owner write down how the business actually ran day to day, so it didn't depend only on them. When the business went to market, buyers moved through their review quickly, didn't cut the price for key-person risk, and the deal closed on the original schedule for more than the owner first expected.
Asset Sale or Share Sale?
In a share sale, you sell the shares of your company. The company keeps its assets, its employees, and its debts; only the owner changes. In an asset sale, the company sells specific things it owns, and the buyer picks what to take on.
| Question | Asset Sale | Share Sale |
|---|---|---|
| What gets sold | The corporation transfers chosen assets, and sometimes specific debts it agrees to hand off. | The seller transfers shares of the corporation. The corporation keeps everything it already owns. |
| Who keeps old debts | The seller's corporation usually keeps debts it didn't specifically hand off, subject to the deal terms and the law. | Debts generally stay inside the corporation, which now belongs to the buyer. |
| Taxes | The corporation may owe tax on selling its assets, and there may be more tax when money is paid out to the seller. | The seller usually reports a capital gain, and may qualify for the lifetime capital gains exemption if the rules are met. |
| Approvals needed | Assets, contracts, permits, employees, and leases may each need their own transfer, assignment, or consent. | Fewer individual transfers are usually needed, but change-of-ownership and regulatory approvals can still apply. |
| Risk after closing | Risk usually comes from debts you kept, broken promises, and duties during the handover. | Risk usually comes from broken promises, tax issues, and problems found in the company after closing. |
Sellers often prefer share sales. A share sale can mean your profit counts as a capital gain, and in some cases you may qualify for the lifetime capital gains exemption, a tax break that can shelter part of your profit from tax. But a buyer taking over shares also takes on the company's full history, including old debts, unless the deal says otherwise.
An asset sale lets you and the buyer pick which assets and debts move over, though some laws and the deal documents can still pass along risk you didn't expect. Selling assets can trigger tax at the company level, and then again when the money is paid out to you personally. Sales tax (GST/HST) may not apply if you and the buyer qualify for, and properly claim, an election available for selling a business. Buyers sometimes prefer buying assets because it can give them a fresh tax value in what they buy, but licences, contracts, and leases may not automatically come along with the assets.
The lifetime capital gains exemption isn't automatic. Rules about how long you owned your shares and how your company used its assets can put the exemption at risk, so model the numbers before you sign anything.
Among other requirements, your shares must count as “qualified small business corporation shares” when you sell, which brings in rules about your ownership period and how the company's assets were used. Too much idle cash, or investments not used in the business, can jeopardize your claim. Because of details like these, get a tax advisor to model your structure, asset allocation, and elections before you sign a letter of intent.
What Happens During Due Diligence
Once you sign a letter of intent, the buyer's team will dig through your financial statements, tax filings, corporate records, contracts, leases, employee and contractor details, intellectual property, privacy practices, regulatory compliance, environmental matters, and any disputes. If you keep this material organized in one place, answer honestly, and update your answers as facts change, the process moves faster and you're less likely to face a surprise price cut near the end.
In an Ontario asset sale, the buyer may offer jobs to some or all of your employees. But simply calling it an “asset sale” doesn't wipe the slate clean on their employment history. Under section 9 of Ontario's Employment Standards Act, 2000, when certain conditions are met, an employee's job is treated as continuing rather than ending just because the business changed hands, and their time worked for you counts toward their time with the buyer. This deemed continuous employment carries real weight: any severance obligation that built up while the employee worked for you carries over and becomes the buyer's obligation, not something you can leave behind by structuring the deal as an asset sale. That's different from most other Canadian provinces, where an asset sale can genuinely end the employment relationship, letting the seller and buyer treat the workforce as a clean slate if they choose to. In Ontario, there generally isn't a clean slate. Other rules, like reasonable notice under common law, union contracts, benefit plans, and money already owed to employees, need their own review. Your purchase agreement can spell out who's responsible for what, but that allocation doesn't erase an employee's own legal rights.
Contracts don't all transfer the same way. Handing over a contract's benefits isn't the same as handing over its duties, and it may not release you from the contract. Sometimes you need a new agreement (an assumption agreement) or a formal swap of parties (a novation). Check your contracts, leases, loan documents, and licences for clauses that restrict handing them over, or that get triggered by a change of ownership. Then build any needed approvals, sign-offs, or replacement permits into your closing conditions. Even a share sale, which usually avoids a technical assignment, can still trigger a change-of-control consent requirement.
Negotiating Promises and Protections
The purchase agreement will include promises, called representations and warranties, about you, your business, its assets, and its debts. These promises spread the risk of what's unknown and support the buyer's review, but they don't replace telling the buyer everything upfront. As the seller, you'll want to soften some promises with words like “material,” “to my knowledge,” or a cutoff date, and list any exceptions clearly, while keeping your disclosures accurate right up to closing.
Indemnities set out what happens if a promise turns out to be false, or if a specific liability shows up later. Common protections include: a time limit on how long a claim can be made, a minimum loss before a claim counts, a per-claim minimum, a total cap on what you might owe, rules for giving notice and handling a claim, and rules that stop the buyer from being paid twice for the same loss. Tax matters, fraud, and excluded liabilities often get different, and usually higher, limits. Insurance built for this kind of deal, called representation and warranty insurance, can shift some of this risk off you, but it comes with its own exclusions and requirements, so it doesn't replace careful drafting.
We were brought in after closing to help a seller who, on an earlier deal, had agreed to an unlimited promise covering every statement in the contract, just to beat a competing buyer's deadline. About a year later, a promise about employee matters turned out to be inaccurate. The seller ended up paying far more than the money already held back, straight out of personal funds. A cap tied to part of the purchase price, which is standard and something most buyers will accept, would have prevented the loss entirely.
Getting Paid: Cash, Earnouts, and Vendor Financing
Not every deal is paid in full, in cash, on closing day. An earnout ties part of the price to how well the business performs after you leave. Earnouts can turn into disputes if the target isn't crystal clear, if the accounting rules aren't spelled out, if day-to-day control of the business isn't defined, or if you can't check the numbers yourself. Write the formula down with examples, decide how one-time or unusual items are treated, and set clear dates for when amounts are calculated and paid.
With vendor financing, you become the lender. The buyer owes you money, and you take on their risk of not being able to pay. The IOU, called a promissory note, should ideally come with guarantees and a security agreement that clearly describes what backs it up. Under Ontario's Personal Property Security Act, having a security interest (called attachment) isn't the same as protecting your place in line if the buyer owes other people too (called perfection). Search for existing claims against the buyer, register your interest promptly under the right name and in the right place, address what happens to money the buyer collects using your collateral, and negotiate priority with any bank the buyer already owes. Security lowers your risk. It doesn't guarantee you'll get paid, and bankruptcy law can pause or change your ability to collect.
Closing and What Comes After
Closing isn't just signing one piece of paper. Your lawyer will typically coordinate the flow of funds, pay off existing debts, arrange releases of old claims, apply price adjustments, complete tax elections, gather required approvals, handle resignations of old officers, and update corporate and government records. If money or documents sit in escrow until a condition is met, agree on how and when they'll be released well before closing day. After closing, you may still owe things like final adjustments, help during the transition, records the buyer needs, tax cooperation, and handling any claims that come up.
To protect what they paid for, a buyer will often ask you to promise not to compete with the business, or poach its staff or customers, for a set period of time. Ontario courts look closely at these promises, but they judge one made as part of selling a business more generously than one in an employment contract. Even so, the promise needs limits: it should cover no more than it truly needs to, in what it restricts, where it applies, and how long it lasts, or it risks being struck down as unenforceable. Make sure it lines up with any employment or consulting agreement you sign as part of the deal, and get advice on the exact wording for your situation, since competition law can also come into play and a generic clause rarely fits well.
Five Common Mistakes
- “Waiting too long to start preparing limits your options.”
- “Picking a deal structure before getting tax advice can cost you real money.”
- “Going into due diligence unprepared shakes buyer confidence.”
- “Missing a required approval can delay, or derail, your closing.”
- “Leaving payment, protection, or after-closing terms vague invites disputes.”
Ontario FAQs
It depends on your taxes, your liabilities, what approvals you need, and what you want out of the deal. Get tax and legal advice before you sign a letter of intent.
Start early enough to organize your records, deal with any risks, and complete tax or corporate planning that takes time to set up properly.
Not automatically, but Ontario's employment standards rules can preserve their length of service and require you to carefully divide up responsibilities with the buyer.
Check your leases, contracts, loan documents, permits, and licences for clauses about transfers or changes in ownership.
Use clear, well-defined price adjustment and earnout terms, and if you're offering seller financing, back it with guarantees, security, and a clear priority arrangement.
