Do You Need a Business Valuator Before You Buy in Ontario?

Should you hire an independent business valuator before buying an Ontario business, or trust the broker's or accountant's numbers? Here's how to decide.

Key takeaways
  • An independent business valuator is engaged by you, the buyer, and owes you the analysis rather than the seller.
  • There's no fixed rule for when a valuation "pays for itself" — that depends entirely on the deal, and this article won't invent a threshold that doesn't exist.
  • - The purchase is small enough, relative to your overall resources, that the downside of overpaying moderately is manageable.

Every business for sale comes with a number attached to it, usually produced by the seller's broker or accountant. The question buyers rarely ask early enough: whose interests does that number actually serve? A broker is typically paid on the sale closing, and an accountant working for the seller is working for the seller.

This doesn't mean every asking price is inflated or unreliable — many are reasonable. It does mean the number in front of you wasn't necessarily built for your benefit, and deciding whether to pay for an independent opinion is a real decision, not a formality.

What an independent valuator actually does

An independent business valuator is engaged by you, the buyer, and owes you the analysis rather than the seller. Depending on scope, that can include reviewing the business's financial statements and normalizing earnings (adjusting for one-time expenses, owner's discretionary compensation, and related-party transactions that distort the real picture), assessing the reasonableness of the asking price against comparable considerations, and identifying red flags in the numbers that a quick read wouldn't catch.

This is a different exercise from the accounting due diligence your own accountant may do on the deal generally — a valuator's specific job is opinion on value, though in practice the two often overlap and firms sometimes provide both.

When an independent valuation is worth the cost

There's no fixed rule for when a valuation "pays for itself" — that depends entirely on the deal, and this article won't invent a threshold that doesn't exist. But a few situations tend to make an independent valuation more clearly worthwhile:

When it may be less critical

Valuator, broker, and accountant: who does what

RoleWho typically engages themPrimary loyaltyTypical focus
Business brokerSellerSellerMarketing the business, negotiating a sale price
Seller's accountantSellerSellerFinancial statements, tax filings, sometimes normalized earnings for marketing
Buyer's accountantBuyerBuyerReviewing the target's financials, tax structuring for the buyer
Independent business valuatorWhoever hires them (often the buyer)Whoever hires themAn opinion of value, built on the buyer's or their own analysis

This table doesn't mean brokers or sellers' accountants are unreliable — many produce accurate, defensible numbers. It means their engagement isn't structured to represent your interests, and treating their figure as neutral by default is the mistake to avoid.

Never state a "typical" valuation multiple

You may see rules of thumb online — a number of times revenue, or a multiple of earnings, said to be "standard" for a given industry. Treat these skeptically. Valuation is deal-specific and industry-specific, shaped by growth trends, customer concentration, owner dependency, and dozens of other factors that a generic multiple can't capture. A number that looks reasonable in the abstract can be badly wrong for a particular business, in either direction.

What an independent valuation doesn't replace

A valuation opinion is not the same as legal due diligence. It won't tell you whether the lease is assignable, whether there are undisclosed liabilities, or whether the corporate records are in order. Those questions are answered through the legal and financial due diligence process alongside your purchase agreement — a valuator's opinion on price and a lawyer's review of the deal's legal risks are complementary, not substitutes for each other.

Frequently asked questions

Will a bank or lender require their own valuation anyway?

Often, yes, if you're financing part of the purchase — many lenders require an independent valuation or appraisal as a condition of the loan. If that's your situation, ask early whether getting your own valuation before you negotiate could work in your favour rather than duplicating the lender's process later.

Can I just rely on the seller's financial statements without any independent review?

You can, but doing so means accepting the seller's framing of the numbers without a check. Even a lighter-touch review by your own accountant, short of a full formal valuation, is generally worth doing before you commit to a price.

Does a business valuator replace the need for a lawyer?

No. A valuator addresses price; a lawyer addresses the legal structure of the deal, the purchase agreement, liability allocation, and closing mechanics. Most buyers need both, working alongside each other rather than one substituting for the other.

What happens if the valuation comes back lower than the asking price?

That becomes a negotiating point, not necessarily a deal-breaker. Sellers and buyers routinely negotiate off an independent number, and the outcome depends on how motivated each side is and what else is on the table.
