A plain Ontario checklist for buyers: asset or share purchase, franchise disclosure, employees, the lease, liens and tax steps to confirm before you pay.

Key takeaways
  • How you structure the purchase, assets or shares, decides which liabilities and tax steps come with the business.
  • A franchise buyer must generally receive a disclosure document at least 14 days before the earlier of signing a franchise-related agreement or paying any consideration to the franchisor, subject to the exceptions in the Act and its regulation.
  • Check the lease, liens, WSIB and tax elections before closing, because several have timing rules that are hard to fix afterwards.

You have found a business you like, the numbers look workable, and the seller wants an offer. Before any money changes hands, there are legal items that are much easier to deal with now than after closing.

This checklist walks through what to confirm, negotiate and sign when buying a business in Ontario. It is general information, not advice on your deal, because the right answers depend on how the purchase is structured and what the business actually owns.

Decide whether you are buying assets or shares

In an asset purchase you buy particular things, such as equipment, inventory, the name, customer lists and the lease. In a share purchase you buy the corporation itself. The structure affects nearly every item below.

Ontario's Bulk Sales Act was repealed on March 22, 2017, so buyers of business assets no longer have to follow bulk sales procedures. If a page tells you otherwise, it is out of date. One related rule remains: where the seller holds, or must hold, a retail sales tax vendor permit, the Retail Sales Tax Act still requires the seller to get a certificate from the Minister, and a buyer who does not get the duplicate certificate is responsible for the seller's unpaid taxes, penalties and interest.

If it is a franchise, disclosure comes first

A franchisor must give you a disclosure document at least 14 days before the earlier of signing any agreement relating to the franchise or paying any consideration to the franchisor. It must be delivered as one document at one time, and the franchisor must give you a written statement of any material change before you sign or pay.

The document should cover the franchisor's background, litigation, bankruptcy history and financial statements, plus the costs, proposed agreements, territory, supplier restrictions, termination, renewal and transfer terms, training, advertising funds and a list of current and former franchisees.

There are exceptions. For example, disclosure is not required when an existing franchisee resells for its own account without the franchisor being involved in the grant, and the regulation sets exemptions for total initial investments of no more than $15,000 or more than $3,000,000. Whether one applies to your purchase is worth confirming before you rely on it.

Employees and non-competition promises

Buyers usually want the seller not to compete. Since October 25, 2021, the Act bans non-compete agreements between employers and employees. There are exceptions for a non-compete agreed as part of a sale of a business where the seller immediately becomes the buyer's employee, and for an employee who is an executive, such as a CEO, president or chief financial officer. The ban does not prohibit non-competes entered into before that date. If your seller does not fit these situations, how a non-compete is treated depends on the facts, so it is worth confirming with a lawyer before you rely on it.

Lease, liens and tax steps before closing

The GST44 election cannot be used if the seller is a GST/HST registrant and the buyer is not. If the seller is a non-resident selling taxable Canadian property, special withholding rules can apply to you as buyer.

What to do next

Before you sign an offer or letter of intent, make sure it is conditional on the checks above. Then:

Frequently asked questions

Do I still need to follow bulk sales procedures in Ontario?

No. The Bulk Sales Act was repealed on March 22, 2017, and buyers of business assets no longer have to comply with bulk sales procedures. A retail sales tax rule can still apply if the seller holds, or must hold, a vendor permit.

Is a share purchase safer than an asset purchase?

Not automatically. In a share purchase the corporation keeps its own WSIB account and any amounts owing. That means you inherit its history, so checking it matters even more.

Do I need a WSIB purchase certificate?

In an asset purchase, the WSIB says buyers should get one, requested before the sale date and valid for 30 days. In a share purchase it is not required.

Will the seller's employees keep their service?

Under the Employment Standards Act, 2000, if you employ them, their time with the seller counts for ESA purposes. A gap of more than 13 weeks before you hire them is an exception.
