Key takeaways
  • Since October 25, 2021, Ontario's Employment Standards Act prohibits employers from entering non-compete agreements with employees, with exceptions for the sale of a business run as a sole proprietorship or partnership and for executives.
  • The sale-of-business exception covers a sole proprietorship or partnership where the seller becomes the buyer's employee, and the Ministry reads it as not covering the sale of a corporation.
  • Non-competes with executives are not prohibited, and non-solicit and non-disclosure agreements fall outside the ban.

If you are buying a business, you probably want to stop the seller, and sometimes the staff you take on, from setting up nearby and taking customers with them. A non-compete seems like the obvious tool. In Ontario, though, it is not always available.

The Employment Standards Act (ESA) restricts non-competes with employees, but it has exceptions that matter in a business sale. Which one applies depends on who is signing, what kind of business is being sold, and the role the person will have afterward.

Ontario's general ban on employee non-competes

Since October 25, 2021, the ESA prohibits employers from entering non-compete agreements with employees. The ban covers agreements made before, during or after employment.

Agreements made before that date are not prohibited by the ESA. Whether an older agreement can actually be enforced is a separate question that a lawyer can help you assess.

For a buyer, this means you generally cannot ask the seller's staff to sign a new non-compete as a condition of coming across to your business, unless one of the exceptions fits.

The sale-of-business exception

The ESA ban does not apply where a business, or part of one, run as a sole proprietorship or partnership is sold or leased, the seller becomes the buyer's employee immediately after, and the parties sign a non-compete as part of the sale.

All of those pieces matter. Think of it as a checklist:

The Ministry's manual reads this exception as working only where the seller is an individual or individuals, so it does not cover the sale of a corporation.

When the seller is a corporation

Many businesses are owned through a corporation. In that case, a non-compete between the corporate seller and the buyer is treated as a commercial covenant rather than an employment non-compete.

That is different from non-competes with the seller's employees. Those remain barred unless an exception applies.

Whether a commercial covenant is reasonable and enforceable in a given deal is a question of contract and court law, not of the ESA. A lawyer can review the wording, the length of the restriction and the area it covers before you rely on it.

Executives and other tools that stay available

Non-competes with an executive are not prohibited. For this purpose, an executive is someone who holds the office of:

The ban also does not reach non-solicit and non-disclosure agreements. If your real concern is customer lists, confidential information or staff being poached, these may fit better than a non-compete for ordinary employees.

An employee who signed a prohibited non-compete, or who faced reprisal for refusing one, can file an ESA claim with the Ministry of Labour. Disputes about enforceability can still go to court.

What to do next

Before you sign a purchase agreement, work out who is actually giving the restriction and in what capacity. The answer decides whether the ESA ban is even in play.

Frequently asked questions

Can I make every employee sign a non-compete when I buy a business?

Generally no. Since October 25, 2021, the ESA prohibits employers from entering non-compete agreements with employees, unless an exception applies. Non-solicit and non-disclosure agreements fall outside the ban.

Does the sale-of-business exception work if the seller owns a corporation?

The Ministry's manual reads the exception as working only where the seller is an individual or individuals, so it does not cover the sale of a corporation. A corporate seller's non-compete with the buyer is treated as a commercial covenant.

Can an executive be asked to sign a non-compete?

Yes. Non-competes with an executive are not prohibited. The ESA lists the offices that count, including CEO, president and CFO, plus any other chief executive position.

What can an employee do if they were made to sign a prohibited non-compete?

They can file an ESA claim with the Ministry of Labour. This also applies if they faced reprisal for refusing to sign. Disputes about enforceability can still go to court.
