Key takeaways
  • Parties to a business agreement may vary or exclude limitation periods, so the agreement itself can set how long the seller stays exposed on its representations.
  • If you are paid over time, registering your security under the Personal Property Security Act matters if the buyer becomes insolvent.
  • Most closing conditions turn on approvals, tax elections and employee matters that depend on your deal structure.

When a buyer sends you a draft purchase agreement, it is usually written to protect the buyer. As the seller, you have room to negotiate, but only if you know which clauses carry the real risk.

This article explains the main parts of a business sale agreement in Ontario and where sellers commonly focus. It is general information, and a lawyer should review your actual draft before you sign.

Start with the structure: shares or assets

A share purchase agreement transfers your shares in the corporation. An asset purchase agreement transfers the business assets, contracts and sometimes employees. The structure changes almost every other clause, including tax, approvals and what liabilities stay with you.

The agreement is usually a business agreement, one where no party is a consumer under the Consumer Protection Act, 2002. That allows the parties to vary or exclude limitation periods, which is why the agreement can set its own survival period for representations and warranties.

Price, adjustments and payment terms

Look closely at how the price is calculated and paid. Sellers commonly review working capital or inventory adjustments, holdbacks, earn-outs and any portion paid after closing. Ask how each adjustment is measured and who decides disputes.

If part of the price is paid after closing, tax and security both matter. A reasonable capital gains reserve may be available where part of the price is not payable until after the end of the tax year, with at least one-fifth of the gain included each year. If you sell qualifying shares to your child who was resident in Canada, the spread can be up to 10 years.

For security, a seller who takes back a loan can register a financing statement in the PPSA registry over the business assets. An unperfected security interest is not effective against a trustee in bankruptcy, so an unregistered seller may rank as unsecured. A registration is effective only for its registration period, so you must renew it before it expires if the loan is still outstanding. If the buyer defaults, a secured party intending to dispose of collateral must generally give at least fifteen days' written notice, and the debtor may redeem before disposition by fulfilling the secured obligations and paying reasonable enforcement expenses.

Representations, warranties and indemnities

Representations are your statements of fact about the business: its finances, contracts, employees, taxes and compliance. An indemnity is your promise to compensate the buyer if those statements turn out to be wrong. This is where sellers often carry the most risk after closing.

Without a contract term, claims are generally subject to the Limitations Act, 2002. A proceeding cannot be started after the second anniversary of the day the claim was discovered, unless the Act provides otherwise. No proceeding can be started after the 15th anniversary of the act or omission, regardless of discovery. Because the parties can vary these periods in a business agreement, the survival clause deserves careful attention.

Closing conditions and tax clauses

Closing conditions list what must happen before either side has to complete. For many sales they include:

Some regulatory notices depend on who the buyer is and how large the deal is. A non-Canadian making an investment that is subject to notification under the Investment Canada Act must notify the Director at any time before the investment is implemented or within thirty days afterward. For very large deals, the Competition Bureau must generally receive advance notice where the target's Canadian assets or sales exceed the transaction-size threshold, which remains at $93 million in 2026, and the parties and their affiliates have combined Canadian assets or revenues exceeding $400 million. Whether either applies to your sale depends on the facts, so it is worth confirming with a lawyer.

Frequently asked questions

How long can a buyer make a claim after closing?

It depends on the agreement. Parties to a business agreement may vary or exclude limitation periods. Without that, the general rule is two years from discovery of the claim, with a 15-year outer limit.

Should I register security if the buyer owes me money after closing?

Generally that is worth discussing with a lawyer. Registering a financing statement perfects a security interest, and an unperfected interest is not effective against a trustee in bankruptcy. You also need to renew before the registration expires.

Do employees stay with the business after a sale?

Those the buyer hires keep their length of service for entitlements such as vacation and notice of termination. That does not carry over if the buyer hires them more than 13 weeks after the earlier of their last day or the sale. What you owe employees the buyer does not hire depends on the facts.

Can I avoid GST/HST on an asset sale?

Sometimes. A joint election on Form GST44 can mean no GST/HST is payable where the buyer acquires all or substantially all of the property needed to run the business. Even with an election, tax still applies to a taxable service the seller will render, a taxable lease or licence of property, and, where the buyer is not a registrant, a taxable sale of real property. The election is also not available where the seller is a registrant and the buyer is not.
