To value a small business before buying, buyers typically use an earnings-multiple method, either SDE (Seller's Discretionary Earnings) or EBITDA, adjusted for add-backs and normalised for owner-specific costs. Asset-based valuation sets a floor, and a discounted cash flow analysis provides a growth-oriented check. In Canada, multiples for small businesses generally range from roughly 1.5x to 6x earnings, depending on industry and risk.
That short answer hides a lot of nuance. Learning how to value a small business is the single most important piece of preparation a buyer can do before signing anything, because the number you arrive at protects you from overpaying and gives you a defensible position at the negotiating table. The sections below walk through each valuation approach, how to test the seller's earnings figures, and how the valuation feeds directly into the legal side of the deal in Ontario.
Why Valuation Is the Buyer's Starting Point, Not the Seller's Asking Price
The first thing to understand is that an asking price is not a valuation. It is a starting point for negotiation. Sellers list at the number they want, often anchored to what they need for retirement or what a broker told them the business might fetch. A buyer, by contrast, should pay what the business is actually worth based on its earnings, assets, and risk profile. These two numbers are rarely the same.
A business is ultimately worth what a willing buyer and a willing seller agree it is worth. But you cannot negotiate toward "fair" if you do not know what fair looks like. Doing your own valuation before you ever discuss price gives you an independent benchmark, so the seller's asking price becomes one data point rather than the gravitational centre of the whole negotiation.
This matters in Ontario M&A because the Letter of Intent is typically the first document where a price gets committed to in writing, even loosely. By the time you reach that stage, your valuation work should already be done. Most buyers anchor on one of three approaches: earnings-based multiples, asset-based valuation, and discounted cash flow. None of this assumes bad faith on the seller's part. Sellers generally act honestly, but they have every incentive to present the business in its best possible light, and the buyer's job is to test that picture.
How to Value a Small Business Using Earnings Multiples: SDE vs. EBITDA
Most small business acquisitions in Canada are priced on a multiple of earnings. The two metrics you will encounter are SDE and EBITDA, and choosing the right one depends largely on the size of the business and how dependent it is on its current owner. Getting this small business valuation Canada framework right is the foundation of the whole exercise.
Seller's Discretionary Earnings (SDE) for Owner-Operated Businesses
Seller's Discretionary Earnings is the metric used for smaller, owner-operated businesses, generally those with revenue under roughly $2 million to $5 million where one owner is actively running things day to day. SDE starts with net income and adds back the owner's salary and compensation, interest, taxes, depreciation, amortization, and personal expenses run through the business. The logic is that a single full-time owner draws a salary and runs some personal costs through the company, and SDE strips those out so buyers can compare businesses on a like-for-like basis.
Typical SDE multiples for Canadian small businesses fall in an illustrative range of roughly 1.5x to 3x SDE, though the actual figure depends heavily on the risk factors discussed later. Here is a simple example in Canadian dollars. Suppose a business earns $150,000 in net profit, the owner pays themselves a $100,000 salary, and a personal vehicle worth $10,000 a year runs through the company. SDE would be $260,000. At a 2.5x multiple, that points to an indicated value of $650,000.
EBITDA Multiple for Larger, Manager-Run Businesses
EBITDA stands for earnings before interest, taxes, depreciation, and amortization. The key difference from SDE is that EBITDA does not add back full owner compensation. Instead it assumes a market-rate manager would be hired to replace the owner, so a normal salary for that role stays as an expense. EBITDA is the right metric when the business has a genuine management layer and does not depend on the founder being in the building every day.
For the Canadian lower middle market, where enterprise values run from roughly $3 million to $50 million, EBITDA multiples typically sit in an illustrative band of about 4x to 8x. For small to medium-sized businesses, the Business Development Bank of Canada (BDC) describes a common range of roughly 3x to 6x EBITDA, depending on market conditions. For micro-businesses earning under $1 million in EBITDA, the range often compresses further. Treat all of these as starting reference points, not guarantees. A business carrying several of the discount factors covered below may trade beneath the floor of these ranges, while a business with premium characteristics can exceed the ceiling.
Asset-Based Valuation: When Earnings Aren't the Story
The asset approach values a business by its balance sheet rather than its profits. You take the fair market value of all tangible assets, equipment, inventory, vehicles, and real estate, then subtract liabilities to arrive at net asset value. Importantly, this uses fair market value, not the book value sitting on the financial statements, which is why it is sometimes called the adjusted net asset method.
Buyers lean on this approach in a few situations. It is useful for asset-heavy businesses such as manufacturing, construction, or a restaurant with significant owned equipment. It is also the right lens when a business has weak or no profitability and is really being acquired for what it owns. Finally, it works as a floor check. If the asset value comes out higher than the value implied by the earnings multiple, that is a signal worth investigating, because it may mean the business is not earning a reasonable return on the capital tied up in it.
The limitation is that asset value ignores goodwill, customer relationships, brand, and operating systems, so it often understates a healthy going concern. Deal structure also affects how this plays out. In a share purchase of an OBCA or CBCA corporation, the buyer acquires the company's assets indirectly along with its liabilities, including liabilities that may be contingent or undisclosed. In an asset purchase, the buyer can generally choose which assets to acquire and, subject to the purchase agreement, leave unwanted liabilities behind. That distinction changes both the risk profile and the price, and it is worth understanding the trade-offs in share purchase versus asset purchase before you settle on a structure.
Discounted Cash Flow (DCF): Valuing Future Potential
A discounted cash flow business valuation looks forward rather than backward. You project the company's free cash flows, usually over three to five years, then discount those future flows back to today's dollars using a discount rate that reflects how risky the business is. A higher-risk business gets a higher discount rate, which lowers the present value, because future money from a shaky business is worth less today than future money from a stable one.
DCF earns its keep when a business has a strong growth trajectory, proprietary products, or long-term contracts that make future revenue genuinely predictable. The catch for small businesses is that the projections are speculative, and a seller will naturally present optimistic forecasts. A buyer has to stress-test every assumption behind those numbers.
In practice, most buyers of small Ontario businesses anchor on an SDE or EBITDA multiple and use DCF only as a cross-check. If the DCF value comes out far below the multiple-based number, that gap is a red flag worth probing before you commit to a price.
Normalising Earnings: What Add-Backs Are (and Which to Scrutinise)
This is where buyer due diligence meets valuation head-on. Normalising earnings means adjusting reported profit to reflect what the business would really earn for a new owner. The adjustments are called add-backs, and sellers love them because each one increases adjusted SDE or EBITDA and therefore the price. Some add-backs are perfectly legitimate. Others do not survive scrutiny.
Legitimate add-backs that buyers should generally accept include the portion of an owner's salary that exceeds the market rate for a replacement manager, genuinely one-time and non-recurring expenses such as legal fees from a single dispute or costs from a flood, true personal expenses run through the business like a personal vehicle or club memberships, and non-cash charges such as depreciation and amortization.
The add-backs that deserve hard questions are different in character:
- An owner-salary adjustment that assumes the owner can simply be replaced, when in fact the owner personally holds every key customer relationship and most of the operating knowledge.
- One-time revenue items dressed up as if they were recurring.
- Expenses labelled "non-recurring" that somehow appear in two or three consecutive years.
- Related-party transactions priced at non-arm's-length rates, such as below-market rent paid to a relative who owns the building.
There is also a tax dimension. The Canada Revenue Agency reviews business equity valuations and the reasonableness of normalisation adjustments through its valuation function, and CRA Information Circular IC89-3, Policy Statement on Business Equity Valuations, sets out the agency's policy on valuing the equity of closely-held corporations for income tax purposes. Unreasonable add-backs can create exposure on the tax side after closing, which is one more reason to keep your adjustments defensible.
Consider a concrete example. A seller claims an adjusted SDE of $400,000 after add-backs. Reviewing three years of T2 corporate tax returns and financial statements, the buyer's lawyer and accountant find three things. First, a "one-time" legal expense actually appeared in two consecutive years, making about $30,000 of add-backs questionable. Second, the owner's son sits on payroll at $60,000 but will not stay after the sale, which is a legitimate add-back once confirmed. Third, a single customer responsible for $80,000 of revenue, around 20 percent of the total, has not renewed and that risk is nowhere reflected in the SDE. After this analysis, a more honest adjusted SDE lands near $370,000. At 2.5x, that is $925,000 against the seller's implied $1,000,000, a meaningful gap created entirely by testing the numbers.
What Drives the Multiple: The Qualitative Factors
Two businesses with identical EBITDA can command very different multiples, because the multiple is really a measure of risk and durability. Understanding what moves it lets a buyer justify paying less, or recognise when a premium is genuinely earned.
Factors that tend to lift the multiple include:
- Recurring revenue. Businesses built on subscriptions, service contracts, or maintenance agreements are more predictable than transactional ones, and a strong recurring-revenue base can support a meaningful premium over a comparable transactional model. The size of that premium varies widely by industry and deal, so treat any single multiplier you see quoted as illustrative rather than a fixed Canadian benchmark.
- Customer diversification, with no single customer dominating revenue.
- Low owner dependence, where a management team can run the business after closing.
- A consistent growth trend in revenue and profit over three or more years.
- Proprietary systems, brand, or intellectual property that create a defensible position.
- Clean, well-documented books, which lower due diligence risk.
Factors that compress the multiple include customer concentration, owner dependence, declining revenue, exposure to a cyclical or heavily regulated industry, and informal or undocumented business practices. On concentration specifically, industry commentary suggests that a single customer above roughly 25 to 30 percent of revenue often triggers a valuation discount, and heavy concentration among the top few customers can push the discount higher still. The size of the discount depends heavily on contract terms, with locked-in multi-year contracts cushioning the hit and month-to-month arrangements widening it. Treat these thresholds as directional guidance rather than precise rules, because the right adjustment always depends on the specific business.
Where Legal Due Diligence and the LOI Fit In
This is where the numbers meet the legal process, and where a buyer's risk is either contained or quietly absorbed.
The Letter of Intent is usually the first document where buyer and seller commit, even loosely, to a price and a deal structure. While most of an LOI is generally intended to be non-binding, certain provisions, typically confidentiality and exclusivity, are usually drafted to bind the parties, and Ontario courts have held that an LOI can become binding overall where its language and the parties' conduct show an intention to be bound. Everything covered above is what should inform the price range a buyer puts into that LOI. Several LOI terms interact directly with valuation: whether the price is fixed or subject to a working capital adjustment, holdback, or earn-out; whether the deal is structured as an asset or share purchase, which changes what the buyer actually acquires and therefore what it is worth; and the length of the exclusivity or no-shop period, which protects the buyer from the seller shopping the deal elsewhere while due diligence runs. Our guide to the Letter of Intent process for buying a business goes deeper on how those terms are negotiated.
After the LOI is signed, legal due diligence either validates the valuation or challenges it. The review covers corporate records such as the minute book and share register under the OBCA or CBCA, material contracts and whether key customer agreements are assignable, employment arrangements and termination obligations under Ontario's Employment Standards Act, 2000, real property leases, litigation history, regulatory compliance, and intellectual property ownership. Findings here routinely lead to price renegotiation, and that is a normal part of the process. Suppose due diligence reveals that a key supplier contract contains a change-of-control clause letting the supplier walk away on a sale. That single finding can materially change what the business is worth. The buyer's lawyers are not just checking boxes; they are surfacing facts that affect price.
For transactions of meaningful size, buyers and sellers often engage a Chartered Business Valuator (CBV), the Canadian professional designation governed by CBV Institute, formerly the Canadian Institute of Chartered Business Valuators. For smaller deals, a CPA experienced in valuation may be enough. In either case the buyer's lawyer works alongside the valuator and accountant so that the legal, financial, and valuation perspectives triangulate toward a price that will hold up. If you want experienced counsel coordinating that process, our Toronto mergers and acquisitions lawyers do exactly this work.
A Practical Buyer's Checklist: What to Request Before Making an Offer
Before you put a number in front of a seller, you need the raw material to value the business properly rather than accepting the asking price on faith. Request the following:
- Three years of T2 corporate tax returns, or T1 business income filings if the business is unincorporated.
- Three years of financial statements: income statement, balance sheet, and cash flow statement.
- A list of the top 10 customers by revenue, with the status of each contract.
- Key supplier agreements, with attention to any change-of-control provisions.
- A current employee list with compensation and any written employment agreements.
- Aged accounts receivable and accounts payable schedules.
- A schedule of assets, including an equipment list with age and condition and a current inventory count.
- Any pending or threatened litigation or regulatory proceedings.
- Corporate records, including the minute book, certificate of incorporation under the CBCA or OBCA, and share register.
- Lease agreements, along with landlord consent to assignment where it applies.
Reviewing these documents before due diligence is part of what a thorough buyer and seller both prepare for, and our legal due diligence checklist for preparing a business for sale shows the same exercise from the other side of the table.
Frequently Asked Questions About How to Value a Small Business
How do you value a small business before buying it?
Most buyers value a small business on a multiple of earnings, using SDE for owner-run companies or EBITDA for manager-run ones. You normalise the earnings for add-backs, apply an industry multiple, then cross-check the result against asset value and a discounted cash flow analysis before settling on a price.
What is a typical valuation multiple for a small business in Canada?
Canadian small business multiples generally run from about 1.5x to 6x earnings. Owner-operated firms valued on SDE often sit near 1.5x to 3x, while the Business Development Bank of Canada describes a common range of roughly 3x to 6x EBITDA for small to medium-sized businesses. The exact figure depends on industry, growth, customer concentration, and owner dependence.
What are add-backs and why do they matter when buying a business?
Add-backs are adjustments that restate reported profit to reflect what a new owner would actually earn. They include excess owner salary, one-time costs, and personal expenses. They matter because each add-back raises the earnings figure and the price, so a buyer must test every one before accepting the seller's number.
Do I need a professional valuator to value a small business?
For larger deals, buyers often engage a Chartered Business Valuator (CBV), the Canadian designation governed by CBV Institute. For smaller transactions, a CPA experienced in valuation may be enough. Either way, a buyer's lawyer should coordinate the valuation, financial, and legal review so the agreed price holds up.
