Closing Mechanics in Ontario Business Sales: How They Work and What Can Go Wrong

By: Wes Forgione · Forgione Deal and Corporate Counsel

Current to July 17, 2026

Quick Answer

Closing an Ontario business acquisition means confirming or waiving every closing condition, delivering signed documents and required approvals, and completing funds flow before the deal is truly done.

Parties confirm or validly waive every closing condition and required approval.
Signed documents are released and funds move under an agreed protocol.
Purchase-price adjustments are calculated and any true-up is scheduled.
Transfers and security interests are registered, and liens are discharged or held back.
Post-closing filings, true-ups, holdbacks, and transition obligations get finished afterward.

Key Takeaways

Confirm every closing condition is satisfied or validly waived.
Obtain required corporate, shareholder, lender, landlord and regulatory approvals.
Maintain a current closing checklist assigning each document, signature and filing.
Approve a detailed funds-flow memorandum before money is released.
Calculate purchase-price adjustments consistently with the agreement and plan any true-up.
Use a clear electronic escrow and document-release protocol.
Coordinate PPSA registrations, lien discharges and payoff evidence.
Document escrow, holdback and post-closing obligations, deadlines and responsibility.

By the time a deal reaches closing, the negotiating is done. What is left is execution, and it is more involved than most first-time buyers and sellers expect.

Closing is not a single signature, it is a coordinated sequence laid out in the purchase agreement. Ontario transactions typically close electronically through counsel, often under an agreed escrow or document-release protocol rather than at a physical meeting.

The difference between a smooth closing and a panic is proper drafting and planning by skilled counsel who have handled these types of deals before.

Satisfying Closing Conditions

In the purchase agreement, each party will have a set of conditions that must be met before they are obligated to close the deal. When each party is satisfied that their conditions are met, they may waive those conditions to move toward closing.

A condition generally should be waived only by the party entitled to its benefit, in the form and by the deadline required by the agreement. Any waiver should be express and documented, with care not to waive an unrelated right or a later damages claim.

Most purchase agreements make closing conditional on specified events, such as:

Financing being finalized.
Representations remaining accurate.
Covenants being performed.
Third-party consents being obtained.
Key licences being confirmed.
Landlord consent to an assignment of the lease.

The parties should track who benefits from each condition, and the deadline and evidence required to satisfy it. If a condition fails, the agreement should be clear as to whether closing is delayed, terminated, or completed and under what conditions.

The Consent That Arrived the Morning Of

On one acquisition, a required landlord consent to assign the target's main location lease wasn't finalized until the morning the deal was scheduled to close, after weeks of the landlord's counsel being slow to respond. The closing did ultimately happen that day, but only because we'd built enough buffer into the timeline and had been following up on the consent independently. On the next deal for the same buyer, we began tracking every third-party consent as a standing agenda item from the letter of intent stage onward.

The Closing Checklist

Lawyers on both sides typically work from a closing checklist, or closing agenda, listing every document, signature, filing, and release condition: the closing statement and funds-flow memorandum, corporate resolutions, the bill of sale or share-transfer documents, officer certificates, resignations, releases, and ancillary agreements such as a restrictive covenant, escrow agreement, or transition services agreement.

Depending on the deal, sometimes individuals are signing, and sometimes directors are signing on behalf of a corporation. Corporate approvals are deal-specific, and knowing who needs to sign off is critical. Directors ordinarily authorize the corporation's participation in the transaction and confirm signing authority.

Shareholders may also need to approve the deal. For example, in an asset sale, an Ontario corporation's sale, lease, or exchange of all or substantially all of its property outside the ordinary course engages the shareholder-approval procedure in the Business Corporations Act (Ontario). To ensure proper resolutions are prepared and signed, it is prudent for counsel to review the minute books, constating documents, shareholder agreements, and any lender restrictions that could affect who must approve the transaction.

Signatures, Counterparts, and Escrow Release

Electronic signatures and contracts are typically valid under Ontario's Electronic Commerce Act, 2000, provided the statutory and contractual requirements are met. Accordingly, most deals are signed and closed electronically.

Certain documents and contexts are excluded from the Act or governed by additional formalities, so e-signing should be confirmed document by document.

The purchase agreement and closing agenda should state whether signatures may be delivered in counterparts, when PDF or platform signatures become effective, who may release signature pages from escrow, and whether any original, witness, notarization, or registration requirement still applies.

Adjustments on the Closing Statement

The amount that changes hands at closing is rarely the headline purchase price. It may be adjusted for prepaid rent, property taxes, assumed liabilities, estimated working capital, debt, cash, transaction expenses, and any deposit already paid.

The purchase agreement should control how these adjustments are calculated. It should set out the accounting principles, the hierarchy among applicable rules, a sample calculation, and the treatment of unusual or non-recurring items.

Both sides should review the closing statement and funds-flow memorandum carefully, because errors directly affect how much money moves and to whom.

If the calculation cannot be finalized by closing, the parties commonly use an estimated amount followed by a post-closing true-up. That process should include a post-closing statement, a review and objection period, access to supporting records, an expert-determination process, and a payment deadline. The true-up should not become an opportunity to change the agreed valuation methodology.

Registrations and Filings at Closing

Depending on the deal, closing may require registering financing statements under Ontario's Personal Property Security Act, arranging discharges or amendments of existing registrations, updating corporate records, and filing notices with regulators or licensing bodies.

A registration is not the same thing as the underlying security interest. A broad or stale search result is not automatically proof that a creditor has a valid claim to every purchased asset.

The buyer's counsel should review current debtor-name searches, match registrations to payout letters and security documents, and establish a closing sequence for new registrations, repayment, and discharge evidence.

Depending on leverage and timing, funds may be paid directly to a secured creditor or held back pending registrable discharge documentation. The statute also provides a demand process in specified circumstances after obligations have been performed or the registration is no longer justified.

The Lien That Appeared Between Searches and Closing

On one acquisition, our initial PPSA searches against the target came back clean weeks before closing. As a matter of practice, we re-ran the searches the morning of closing, and this time a new financing statement had been registered against all of the target's assets in the interim. Because we caught it before any funds moved, we held back the corresponding amount in escrow until the lender confirmed the discharge was actually registered, rather than releasing the full purchase price on the strength of a payout letter alone. Re-running PPSA searches on closing day, not relying on searches from weeks earlier, is what caught it.

After Closing

Closing is not necessarily the end of the lawyer's involvement. In an asset deal, the parties should address which employees receive offers, how accrued vacation and other liabilities are allocated, and whether service is treated as continuous for statutory purposes. Ontario's Employment Standards Act, 2000 can deem employment not to have been terminated or severed when a purchaser continues the business and employs the employee.

Payroll, benefits, pensions, union obligations, and common-law exposure require separate, fact-specific review.

GST/HST is payable on the sale unless the parties file a valid election to relieve it, so this needs transaction-specific planning rather than an assumption either way. Where a purchaser acquires all or substantially all of the property necessary to carry on a business or part of a business, the parties may be eligible to make the joint election under subsection 167(1) of the federal Excise Tax Act so that GST/HST does not apply to the sale, subject to its conditions and exclusions; where the purchaser is a registrant, the filing rule in subsection 167(1.1) generally applies. Eligibility, registration status, excluded property, filing responsibility, and indemnities should be confirmed before closing rather than assumed.

An escrow or holdback only works if the agreement spells out how it operates. It should identify the stakeholder, permitted investments, release dates, claim-notice requirements, dispute procedure, tax reporting, fees, and what happens to undisputed amounts. It should also distinguish security held for indemnity claims from a reserve held against a purchase-price adjustment, since the two serve different purposes and can release on different timelines.

Purchase-price true-ups need the same discipline. Without a calendar for delivery, objections, expert determination, and payment, a true-up can drag on indefinitely instead of resolving on a fixed schedule.

Because so many obligations survive closing, counsel should keep a single post-closing list to track them through to completion: final tax elections, minute-book updates, licence transfers, discharge evidence, and any transition or restrictive-covenant obligations.

Five Common Mistakes

“Tracking closing conditions too late.”
“Using an outdated closing checklist.”
“Approving funds flow without verifying every amount and recipient.”
“Releasing funds before registrations or discharge arrangements are secure.”
“Forgetting post-closing deadlines once the deal is done.”
