Before a single offer arrives, most Ontario business sales are quietly decided by how tidy the seller’s legal house already is. Buyers and their lawyers spend the early weeks of due diligence hunting for gaps — a missing minute book resolution, a contract nobody can locate, employee files that don’t match payroll records. Doing legal housekeeping before selling a business gives you time to close these gaps on your own schedule, instead of explaining them under pressure once a buyer has already found them.

None of this work is exotic. It’s mostly organizing what should already exist, updating what has lapsed, and being honest about what’s missing. The earlier you start, the more options you have to quietly fix a gap rather than disclose it as a live problem during negotiations.

This article walks through the main categories a seller should work through, roughly in the order a buyer’s lawyer will ask about them.

Where Buyers Look First: A Category Overview

CategoryWhat a buyer’s lawyer checksWhy it matters
Corporate recordsMinute book, share register, resolutionsConfirms who actually owns the company and that it has been governed properly
Contracts and leasesAssignability, consent requirements, expiry datesDetermines what transfers automatically and what needs third-party sign-off
Employee mattersEmployment agreements, ESA compliance, non-competesAffects liability exposure and what the buyer inherits
Tax and licensingCRA standing, business name registration, permitsConfirms the business can legally keep operating post-sale
Intellectual propertyTrademarks, domains, licencesConfirms the buyer is actually getting what they think they are buying

Each of these categories deserves its own pass before you go to market.

Start With Your Corporate Minute Book

Your minute book is usually the first thing a buyer’s lawyer asks for, and it is often the most neglected document in a small business. At a minimum, it should show a complete share register that matches who actually owns the company today, director and officer resolutions for major decisions (share issuances, dividends, banking changes), and any amendments to your articles of incorporation.

If your corporation is Ontario-incorporated under the Business Corporations Act, obtaining a current corporate profile report or certificate of status from the Ontario Business Registry is a low-cost, useful early step — it confirms your corporation is in good standing before a buyer’s lawyer asks. If it is incorporated federally under the Canada Business Corporations Act, the equivalent good-standing document is a certificate of compliance from Corporations Canada rather than the Ontario Business Registry. Fees for these reports are modest and set by the applicable registry; verify the current amount before relying on it, as figures like this can change.

Contracts, Leases, and Third-Party Consents

Pull together every contract of real significance — leases, supplier agreements, customer contracts, financing agreements, and any franchise or licensing arrangements — and read each one for two things: whether it can be assigned to a buyer, and whether it contains a change-of-control clause that could be triggered by a share sale. Commercial leases deserve particular attention, since assigning a lease generally requires landlord consent. For housekeeping purposes, your job right now is simply to locate everything, confirm it is signed and current, and flag anything that needs a closer legal look before you go to market.

Employee Records and Statutory Compliance

Buyers scrutinize employee files closely because employment obligations can follow a sale in ways owners don’t expect. Make sure every employee has a signed, current employment agreement on file, and that your records match what you actually pay and how you actually classify each role. If any employee — particularly you, as the departing owner — has a non-compete agreement, have it reviewed now. Since October 25, 2021, general employee non-compete agreements have been prohibited under Ontario’s Employment Standards Act, 2000, subject to narrow exceptions for a seller who becomes an employee of the purchaser and for defined executive roles; an outdated non-compete drafted before that change may not be enforceable as written.

Tax Filings, Business Names, and Licences

Confirm your corporation is current on its tax filings and remittances with the Canada Revenue Agency — outstanding arrears are one of the fastest ways to stall a closing. If you operate under a name other than your corporation’s full legal name, check that the name is properly registered under Ontario’s Business Names Act; a buyer who intends to keep trading under your existing name will want this confirmed. Review any operating licences, permits, or industry-specific approvals for current validity and transferability.

Intellectual Property and Insurance

Confirm you actually own — not just use — your trademarks, domain names, and any proprietary processes or software, and that registrations are current. Pull together your insurance policies and confirm coverage matches what you tell buyers about the business; gaps here are an easy, avoidable red flag.

A Pre-Sale Legal Checklist

Frequently asked questions

How far ahead of listing should I start this housekeeping?

There’s no fixed rule, but starting well before you engage with buyers gives you room to fix problems quietly rather than disclose them mid-negotiation. Corporate and contract cleanup can often be done in the background while you’re still deciding whether and when to sell.

My minute book is incomplete or was never properly kept. Is that a deal-breaker?

Not usually. A corporate lawyer can reconstruct a minute book from underlying records — tax filings, bank resolutions, share certificates — and bring it up to date. It’s a common project, not a red flag on its own, as long as it gets fixed before due diligence.

Will a buyer walk away over a small compliance gap?

Rarely on its own. Buyers expect some imperfections in a small business and usually address them through purchase-price adjustments, holdbacks, or specific indemnities rather than walking away. A pattern of gaps, or a gap you tried to hide, is a different story.

Do I need to volunteer problems I find and fix on my own?

Once you’re in a purchase agreement, your representations and warranties need to be accurate — talk to your lawyer about what to disclose and when. Fixing something quietly before it’s ever asked about is usually far better than explaining it after a buyer finds it.
