Key takeaways
  • Your lease wording decides whether and how the landlord must consent, so read it before you promise a buyer the premises.
  • Make the landlord's consent a condition of the sale so you are not bound to close without the location.
  • Even if the lease moves, other parts of the sale, such as employees and GST/HST, follow their own rules.

For many small businesses, the lease is the business. A restaurant, clinic or shop may be worth little to a buyer if it cannot stay at the same address. When the lease says the landlord must approve a new tenant, the sale cannot safely close until that approval is dealt with.

This article explains in plain terms how consent to assign a commercial lease generally works in Ontario, what to look for in your lease and what to do if the landlord says no. The details turn on your lease wording and the facts, so a lawyer should read the document before you commit to a buyer.

What assignment and consent mean

Assigning a lease means transferring your rights and obligations as tenant to the buyer. Whether your lease restricts this, and whether it requires the landlord's written consent, depends on the wording of your lease, so read the clause before you promise the premises to a buyer. A restriction like this usually exists because the landlord chose you as a tenant and wants to be satisfied the replacement can pay the rent and run the business.

Whether you sell the assets of the business or the shares of your company can change what your lease asks of you. How this applies depends on your lease and your deal, so check the wording rather than assuming either way, and confirm with a lawyer.

What to check in the lease first

How a landlord's refusal is treated depends on the lease wording and on the facts, such as the buyer's finances and experience. It is worth confirming with a lawyer before you rely on any assumption about whether a refusal would stand up.

Asking for consent

Approach the landlord early but only once you and the buyer have reached real terms. Landlords commonly ask about the buyer's financial strength, business experience and intended use, and may want a personal guarantee or a deposit. Prepare a short package so the request is easy to approve.

Keep copies of everything you send and the dates, in case a dispute arises later about when the request was made.

If the landlord refuses or delays

A refusal is not always the end. Sometimes the landlord's concern can be met with a guarantee, a larger deposit or a short lease amendment. If the lease limits the landlord's right to refuse, a lawyer can tell you whether the reason given is likely to stand up. If it does not, you may need a different structure, a new lease for the buyer or a decision not to proceed.

This is why the purchase agreement should make landlord consent a condition of closing, with a clear deadline and a right for either side to walk away if consent is not obtained. Without that, you could be bound to a sale that cannot deliver the location.

Other pieces of the sale tied to the lease

Moving the lease does not settle everything. If the buyer keeps your staff, their past service carries over for Employment Standards Act purposes. A GST/HST election, where available, does not remove tax on taxable leases and licences. Your lawyer and accountant should look at those items alongside the lease.

Next steps: find your lease and every amendment, read the assignment clause, tell your lawyer about the buyer before contacting the landlord, and build the consent condition into the offer.

Frequently asked questions

Can a landlord refuse to consent to my sale?

It depends on the lease. Many leases require consent and some limit the landlord's right to refuse, but the exact wording and the facts decide whether a refusal is allowed. Have a lawyer read the clause.

Am I still responsible for the rent after I assign the lease?

It can depend on the lease or a guarantee. Some leases keep the original tenant liable after assignment, so check this before you agree to anything.

Does selling shares avoid the need for landlord consent?

Not always. Some leases treat a change in control of the tenant company like an assignment. Read the wording in your lease.

Do my employees move with the business if the lease is assigned?

If the buyer employs your staff after a sale, their employment is deemed not terminated and their time with you counts toward the buyer for Employment Standards Act purposes. The exception is that prior service does not carry over if the buyer rehires an employee more than 13 weeks after the earlier of the last day with you or the day of the sale. The buyer is not required to hire your employees, and they need not accept. Employees not hired by the buyer within 13 weeks are your responsibility as seller for ESA notice or pay in lieu, and severance pay where applicable.
