Common Mistakes First-Time Business Buyers Make in Ontario

The same handful of mistakes show up again and again in first-time business purchases, usually because they don't feel like mistakes at the time. A buyer skips a step to keep momentum, trusts a number they should have verified, or assumes something works the way it does in a house sale. Each is avoidable once you know to watch for it.

Mistake 1: Treating due diligence as a formality

Buyers who are excited about a deal sometimes move through due diligence quickly, focused on confirming what they already believe rather than genuinely testing it. Thorough diligence means actually reviewing corporate records, financial statements, contracts, leases, employee records, licences, litigation history, and tax compliance — not skimming a summary the seller's broker prepared.

The cost of rushing this step usually doesn't show up until after closing, when an undisclosed liability, an unassignable contract, or an inaccurate financial picture becomes your problem instead of a negotiating point.

Mistake 2: Underestimating the cash needed beyond the purchase price

The purchase price is rarely the full cash requirement. Buyers also need to account for a deposit, closing costs, and the working capital required to actually operate the business from day one — payroll, inventory, and accounts payable don't pause for a transition. Buyers who plan financing around the headline price alone often find themselves undercapitalized in the first few months of ownership.

Mistake 3: Not bringing in a lawyer until the purchase agreement stage

Many first-time buyers assume legal advice only matters once there's a purchase agreement to review. In reality, the letter of intent stage is where important terms get set — and where clauses like confidentiality and exclusivity can bind you even though price typically doesn't. Waiting until the agreement stage means you've already negotiated (and sometimes signed) key terms without legal input.

Mistake 4: Assuming a "clean slate" on employees in an asset deal

It's a common misconception that buying assets rather than shares automatically frees a buyer from any obligations to the seller's employees. Under Ontario's Employment Standards Act, 2000, where a business (or part of one) is sold as a going concern and the buyer hires the seller's employees, that employee's prior service can be deemed to carry over for statutory-minimum purposes — vacation, leaves, notice, and severance entitlements. This is separate from whether the buyer wants to keep those employees at all; it's about what counts toward their entitlements if they're hired.

Mistake 5: Not confirming the lease can actually be assigned

If the business operates out of a leased location, buyers sometimes treat the lease as a minor detail rather than a closing condition. Assigning a commercial lease generally requires landlord consent, and while Ontario's Commercial Tenancies Act means that consent generally can't be unreasonably withheld where the lease restricts assignment, the lease's own terms still control first — and obtaining that consent takes real time and can carry its own conditions.

Mistake 6: Assuming a "standard" non-compete protects you

Buyers sometimes assume they can simply have the departing owner, or any key employee, sign a non-compete as part of the deal. Since October 25, 2021, general employee non-compete agreements have generally been prohibited under the Employment Standards Act. The main exception that lets a purchaser lock in a departing owner's non-compete is where that seller becomes an employee of the purchaser as part of the sale — plus a narrow exception for defined executive roles. A manager who isn't becoming an employee, or a minority shareholder who isn't either, may not fall within either exception.

Mistake 7: Believing there's a "bulk sales" safety net

Some buyers (and sellers) still assume Ontario has a bulk-sales notice regime protecting trade creditors on an asset sale. It doesn't — the Bulk Sales Act was repealed in 2017. Protection against undisclosed seller liabilities today comes entirely from due diligence, representations and warranties, indemnities, and holdbacks built into the purchase agreement — not from a statutory notice process.

Mistake 8: Skipping a lien search on equipment and inventory

Assets can have existing security interests registered against them under the Personal Property Security Act (PPSA) even if the seller doesn't mention it. A PPSA search before closing lets you confirm what you're actually buying is unencumbered, or lets your lawyer build the necessary discharges into the closing mechanics.

Mistake 9: Not getting the deal structure (asset vs. share) right for the actual goal

Some buyers let the seller's preferred structure dictate the deal without understanding what they're giving up. An asset purchase and a share purchase carry materially different consequences for liability, tax, and how contracts transfer — the structure isn't a formality to accept from whichever side proposes it first.

Mistake 10: Not planning for the transition period

Buyers focused on getting to closing sometimes give little thought to what happens the week after. Without a plan for the seller's ongoing involvement (formal or informal), operational knowledge that lived only in the seller's head can walk out the door with them.
