Checklist

Deal red flags checklist

A deal red flags checklist for a Canadian business purchase lists specific findings serious enough, on their own or together, to make a buyer stop and reconsider a deal already in motion — reconstructed financials, cash sales that do not trace to deposits, a landlord who will not commit, a licence that cannot transfer, and revenue sitting in one account.

Reviewed

This checklist covers specific, documented findings serious enough to make a buyer pause a Canadian business deal that is already underway, rather than a general list of early warning signs or a framework for how to think about risk in the abstract. Each item here is something to actually verify against documents and third parties, not something to take on the seller’s account alone, and finding one does not automatically end a deal — it changes what has to happen before the deal can proceed.

Financial findings that go beyond messy paperwork

Check whether the seller’s financial statements were assembled specifically for this sale, rather than kept up all alongFinancials reconstructed shortly before a sale process began need far more independent verification against source records than a business’s actual, ongoing books do.
Trace reported cash sales into the actual bank deposit records, not just the seller’s summaryCash revenue that shows up in a summary but never lands in the bank account is either unreported income you should not rely on, or income that was never real, and neither is good news for a buyer.
Confirm payroll source deductions and HST remittances are actually current, not just described as currentAn unresolved CRA remittance problem can attach to the corporation, and in a share purchase, it becomes the buyer’s liability along with everything else in the company.

Relationships the deal depends on but cannot control

Calculate what share of revenue sits in a single customer account with no long-term contract behind itA business this concentrated is really a bet on one relationship continuing under new ownership, and that relationship does not always survive a change of hands.
Ask directly whether the business could keep running for a month without the owner personally involvedA business this dependent on one person can lose real value the moment that person stops being the one answering the phone and making the decisions.
Ask, late in negotiations, whether staff still have no idea a sale is even being discussedA seller who has kept a deal this quiet this close to closing may be more worried about how staff will react than they have let on, and that reaction becomes the buyer’s problem right after closing.

Approvals and property issues that can stall or sink a deal

Ask the landlord directly for a clear yes or no on consenting to assignment, not a vague responseA landlord who stays deliberately vague instead of committing either way is not neutral — it usually means they are weighing what they can extract from the situation, or quietly leaning toward refusal.
Confirm a licence the business depends on actually transfers with a change of ownership, and check whether reapplication has startedDiscovering late that a licence needs a fresh application rather than a simple transfer can turn a manageable timeline into a genuine threat to the closing date.
Check whether equipment described as owned is actually under an active lease or finance agreementEquipment presented as an asset that turns out to be a liability changes both the real value of the deal and what the buyer is actually walking into on day one.

What a search turns up that the seller never mentioned

Run a corporate and litigation search and compare what it turns up against what the seller has actually disclosedWhether a claim turns out to be minor or serious, one the seller never mentioned raises a bigger question about what else has not been disclosed.
