Intro
Buying an existing business is the path most Canadian entrepreneurs never consider—and it’s usually a mistake. You already know what you want to do, but starting from scratch means fighting uphill for years. Buying a business in Ontario skips the startup grind. You get an established customer base, proven revenue, existing systems, and staff who already know how to run operations.
The catch? Buying a business is more complex than starting one. You need to understand valuation, negotiate the deal, dig into the financials, and navigate legal structures that Ontario businesses use. This guide walks you through every step of buying a business in Ontario—from finding the right opportunity to closing the deal and taking over operations.
Buy business Ontario involves finding a suitable seller, conducting due diligence to verify financials and operations, getting financing (usually through a combination of personal savings and bank loans), negotiating the purchase price, and closing the deal with a lawyer. Most buyers spend 3 to 6 months on the full process. Costs include a lawyer ($2,500–$5,000+), accountant ($1,500–$3,000), and often a business appraiser. The purchase price itself depends entirely on the business’s revenue, profit, and market position.

Where to Find Ontario Businesses for Sale
Most Ontario businesses for sale never hit public listing sites. They’re sold through word-of-mouth, business brokers, and relationships.
Business brokers. These professionals specialize in matching buyers with sellers. They vet both sides, manage confidentiality (critical when a business owner doesn’t want employees or competitors to know they’re selling), and negotiate terms. Expect to pay the broker a commission—usually 8% to 10% of the purchase price—but only after the deal closes. A good broker saves you months of searching and filters out deals that won’t work for you. In Ontario, they’re often members of the Canadian Association of Business Brokers.
Online marketplaces. Websites like BizBuySell.ca and Flippa (for online businesses) list thousands of businesses. You’ll see detailed information on revenue, profit margins, and asking price. The downside is you’ll see dozens of mediocre deals alongside legitimate ones. Treat these as starting points, not the final word on what’s available.
Your network. The best deals often come through accountants, lawyers, bankers, and peers in your industry. People you know have access to owners who want to sell confidentially. If you’re considering buying, start telling your professional network now.
Business auctions. Courts, banks, and insolvency firms sell businesses that have failed or foreclosed. These are often priced lower but come with more risk—you’re buying a distressed operation. Due diligence is even more critical here.
What Financial Numbers Actually Matter
When someone shows you a business they want to sell, they’ll lead with revenue. That’s the wrong number to focus on.
Revenue is vanity, profit is sanity. A $500,000 annual revenue sounds impressive until you realize the profit is $10,000. You’re buying the profit, not the sales. A smaller business with a 30% profit margin is worth far more than a larger one operating at 5% margin.
Look at the three most recent years of financials. You want to see a trend. Growing profit is good. Declining profit is a red flag. Flat profit might mean the business is stable or stuck. Ask for actual financial statements—not summaries from the seller. These should include the income statement (revenue minus all costs), balance sheet (assets, liabilities, equity), and cash flow. If the seller claims profit but can’t show you these documents, walk away.
Understand what profit you’re actually getting. A seller might show “net income” of $100,000, but that number includes their salary. If the owner takes $80,000 as salary, you’re really buying $20,000 in annual profit. Some sellers also claim personal expenses (car, meals, travel) as business expenses to reduce taxable income. These are real deductions for tax purposes, but they’re not costs you’ll necessarily repeat. Your accountant can normalize the financial statements to show you the true operating profit available to a new owner.
Don’t ignore cash flow. A business can be profitable on paper but cash-poor in practice. If customers take 90 days to pay but suppliers demand payment in 30 days, you’ll run out of cash even though the business is “profitable.” Ask about payment terms, inventory turnover, and accounts receivable aging.
How to Value a Business You Want to Buy
Valuation is part art, part science. Most small Ontario businesses sell for 3 to 5 times their annual profit (also called EBITDA—earnings before interest, taxes, depreciation, and amortization). Some premium businesses (strong brand, recurring revenue, long-standing customers) sell for 6 to 8 times profit. Struggling businesses might sell for 2 times profit or less.
The multiple rule. If a business generates $50,000 in annual profit, a 4x multiple means you’d pay $200,000. That multiple depends on how risky the business is, how dependent it is on the owner, and how much growth potential you see.
To determine the right multiple, ask yourself: How likely am I to keep the customers? How much do I need to change to make this business better? How much capital will I need to invest after I buy it? Businesses with loyal customers, strong systems, and low owner dependency are worth more.
| Valuation Factor | Lower Multiple (2–3x) | Higher Multiple (5–8x) |
|---|---|---|
| Customer concentration | One customer is 50%+ of revenue | Revenue spread across 20+ customers |
| Owner dependency | Owner does all the work | Systems and staff run the business |
| Growth trend | Declining or flat profit | Growing 10%+ annually |
| Customer loyalty | Monthly churn is high | Long-term contracts or recurring customers |
| Market position | Small player in crowded field | Clear niche or strong reputation |
Don’t pay for growth that hasn’t happened yet. You might see a business and think, “I can easily grow this by 30%.” That’s a great observation, but don’t pay for it upfront. Negotiate a lower price for the current performance, then prove you can grow it. Some sellers accept an earn-out—you pay a base price now and additional payments if the business hits certain targets within the next 12 to 24 months.
Performing Due Diligence: What You Need to Know
Due diligence is your chance to verify that everything the seller told you is true. This is where most buyers find deal-breakers.
Review three years of tax returns. The T1 Generals (personal tax returns for sole proprietors), T2s (corporate tax returns), and GST/HST returns tell you what the CRA has on file. If the financial statements you saw don’t match the tax returns, ask why. Sometimes there are timing differences; sometimes the seller was doing cash deals they didn’t report (a risk you’ll now inherit).
Check the customer list. Ask for a list of the top 20 customers and their annual spending. If your top customer is leaving, the valuation drops dramatically. Call a few customers to verify they’re real and their relationship is solid.
Verify the lease and location. If the business operates from rented space, you need to know: How much longer is the lease? Can it be assigned to you (transferred to you as the new owner)? Does the landlord approve the sale? What’s the rent, and does it increase? A fantastic business becomes worthless if the landlord won’t renew your lease.
Inspect the inventory and equipment. Walk the location. Check what equipment is included in the sale. Look at inventory—is it dated, slow-moving, or obsolete? Visit during different times to see if the business is actually busy during the hours claimed.
Understand the liabilities you’re inheriting. Are there unpaid taxes, outstanding loans, pending lawsuits, or warranty obligations? If you buy the assets only (not the company shares), you’re not legally responsible for old liabilities. If you buy the shares, you own the entire company, including its debts. More on this below.
Check for regulatory compliance. If the business requires licenses (food service, health and safety, professional certifications), verify they’re current and transferable to you. Some licenses can’t be transferred and require you to reapply. In Ontario, check ServiceOntario or the relevant ministry’s website to confirm.
Financing Your Business Purchase
Most buyers don’t pay cash. You’ll likely use a combination of personal savings, a bank loan, and possibly a seller note (the seller finances part of the purchase).
Bank loans for business acquisition. Canadian banks and the Business Development Bank of Canada (BDC) offer acquisition financing. Banks typically lend 50% to 70% of the purchase price, depending on how strong the business is. You’ll need to put down 30% to 50% from your own funds.
The bank will want to see:
- Personal credit score of 650+
- Three years of financial statements from the target business
- Your personal financial statement
- A detailed business plan for how you’ll run it
- In some cases, a personal guarantee (you’re personally liable if the business defaults)
Seller financing. Some sellers accept a promissory note—they lend you part of the purchase price and you pay them back over 3 to 5 years. This can be a win for both sides. The seller gets a higher effective price (they earn interest), and you get more favorable terms than a bank would offer. Make sure the note is documented by a lawyer so there’s no confusion later.
Timelines and approval. Bank acquisition financing typically takes 4 to 8 weeks once you’ve submitted a full application. BDC can be faster. Have your team (accountant, lawyer, broker) lined up early so you can move quickly when you find the right deal.
Structuring the Deal: Asset vs. Share Sale
Here’s where structure matters for taxes and liability.
Asset sale. You buy the specific assets: customer list, inventory, equipment, goodwill. You don’t buy the company itself. You take none of its old debts or liabilities. This is safer because the seller’s past problems don’t become yours. The downside: you can’t use the seller’s GST/HST registration number or existing business licenses that don’t transfer. Also, asset sales sometimes trigger higher tax bills for the seller (and they’ll negotiate that into the price).
Share sale. You buy the company’s shares, meaning you own the whole business including all its assets and liabilities. If the business has unpaid payroll taxes or an old lawsuit, you own it now. But share sales are simpler operationally—the company’s licenses, GST/HST registration, and customer contracts stay in place without interruption. Most Ontario businesses operate this way, so the seller and their lawyer typically prefer it.
What you choose depends on the business and your risk tolerance. A business with a clean history and transferable assets is a good candidate for an asset sale. A well-established business with tight integration into contracts and licenses is better as a share purchase. Your lawyer will advise you.
Legal and Tax Considerations When Buying a Business
You need a lawyer. Period. Hiring one now costs $2,500–$5,000 and saves you tens of thousands in problems later.
Adjustments at closing. On the day you close, the business stops “performing” for the seller and starts for you. So they’ll receive their share of the revenue earned up to that date, and you’ll get the revenue going forward. This usually includes a working capital adjustment—if there are outstanding customer payments or inventory, you’ll settle the amount at closing rather than waiting. Your lawyer manages these calculations.
Non-compete agreements. Most sales include a clause that says the seller won’t start a competing business for 1 to 5 years within a certain radius (usually 5 to 50 km, depending on the business). This protects your purchase—the seller can’t immediately launch a rival business across the street. Make sure the radius and time period make sense for your market.
Warranties and indemnification. The seller warrants (promises) that certain things are true—no hidden liabilities, all financial statements are accurate, key customers have agreed to continue working with you, etc. If something turns out to be false, you need the right to be indemnified (the seller compensates you). Your lawyer structures this protection.
CRA considerations. If you’re buying shares and the seller has unpaid taxes, you could inherit that liability. The CRA can pursue you if the company owes money. One way to protect yourself is to apply for a clearance certificate from the CRA before closing. This confirms the company has no outstanding tax debt.
Salary and payroll. When you take over, make sure all past payroll, EI, and CPP contributions are paid. If they’re not, you become liable. Again, your lawyer and accountant verify this pre-closing.
Common Mistakes Ontario Business Buyers Make
Falling in love with the business. You find a great business and emotionally commit to buying it. Then you stop asking tough questions. Due diligence gets rushed. You pay more than it’s worth because you’re excited. Take a step back. Good deals exist everywhere. Don’t overpay for this one.
Ignoring the owner’s role. Some businesses are built entirely around the owner. They have deep relationships, handle all major decisions, manage the key client accounts. When the owner leaves, those customers often leave too. Before you buy, assess how much of the business’s success depends on the current owner. If it’s 80%, the business is riskier and worth less.
Underestimating integration costs. You’re bringing your own accounting system, maybe a new website, new suppliers. These changes cost time and money. A buyer often budgets for the purchase price but forgets about the transition budget. Factor in 5% to 10% of the purchase price for integration costs and cash reserves for the first 3 to 6 months.
Not getting a written offer. Handshake deals lead to disputes. Get everything in writing: purchase price, what’s included, what closes when, earnout terms, non-compete details. Your lawyer drafts the purchase agreement.
Skipping the accountant. You hire a lawyer but skip the accountant. Then you discover the finances are a mess, the seller was inflating profit, or there are hidden liabilities. Your accountant costs $1,500–$3,000 and catches these before you commit. That’s the best money you’ll spend.
Frequently Asked Questions
How long does it take to buy a business in Ontario?
From finding a candidate to closing, expect 3 to 6 months. Finding the right business takes 1 to 2 months. Due diligence takes 4 to 8 weeks. Financing approval takes another 4 to 8 weeks. Closing takes 2 to 4 weeks. If you have financing pre-approved and move fast, you can compress this to 2 to 3 months.
Can I buy a business with no money down?
Not typically. Banks and the BDC require 20% to 50% down from your own funds. Some sellers might accept a lower down payment if you offer a higher purchase price, but you’ll still need significant personal capital. Save aggressively or find a co-buyer who can contribute equity.
What happens to the business’s employees when I buy it?
If you’re buying the shares, the employment agreements stay the same. Employees’ contracts don’t change. You inherit their vacation pay liability and any pension obligations. If you’re buying assets only, employment contracts don’t transfer automatically—you’d need to rehire staff and offer new contracts. Transitioning smoothly usually means retaining key employees, at least initially. Consult with an employment lawyer before the sale.
What’s the difference between a broker and a business appraiser?
A broker helps you find and negotiate. An appraiser values the business. You might use both. The broker shows you listings and handles the sale. The appraiser gives you an independent opinion on what the business is worth (often $1,500–$3,000 for a small business). This appraisal helps you negotiate with confidence and satisfies lenders.
Can I negotiate after signing a letter of intent?
Yes, but with limits. A letter of intent (LOI) is non-binding unless stated otherwise. It expresses mutual interest. After the LOI, you enter due diligence and can negotiate based on what you discover. If the financials aren’t what the seller claimed, you can renegotiate the price. But if nothing changes, reopening major terms looks bad and can kill the deal.
Do I need insurance after buying the business?
Yes. You’ll need general liability, property insurance, and probably workers’ compensation if you have employees. Some industries require specific coverage (food service needs health permits, trades need liability insurance). Your insurance broker and the previous owner can advise on what you need. Factor this into your operating budget.
Conclusion
Buying a business in Ontario is a faster path to business ownership than starting from scratch, but it requires discipline. Focus on businesses where profit is strong and stable, where the owner isn’t the whole show, and where you can see a clear role for yourself. Use a lawyer and accountant—don’t skip these to save money. Negotiate hard on price, get everything in writing, and take due diligence seriously.
The biggest mistake is moving too fast or ignoring red flags because you’re excited. Good businesses are listed regularly. You’ll find the right one if you stay patient and methodical. Your first step this week: identify 5 to 10 businesses in your target market and reach out to a business broker. That conversation costs nothing and shows you what’s actually available.
