Key takeaways
  • Whether you need the landlord's consent, and whether it can be refused, depends first on the wording of your lease and the law that applies, so have a lawyer review both.
  • The s.167 election is not available where the supplier is a registrant and the recipient is not, and even with a valid election, tax is still payable on a taxable lease, licence or similar supply of property.
  • Get the landlord's answer in writing before closing, not after.

For many small businesses, the lease is the most valuable part of the sale. A restaurant or shop without its location may be worth far less to a buyer. That is why assigning the lease, meaning transferring your tenant rights to the buyer, often sits at the centre of the deal.

This article explains the questions to ask about landlord consent, how to think about a lease that is silent or a refusal, and the practical steps to take. The answers turn on your specific lease, so a lawyer should review it.

This article covers the law of Alberta.

What assigning a lease means

An assignment moves the tenant's interest in the lease to a new tenant.

An assignment is different from a sublease, where you stay the tenant and give someone else the right to use the space. Buyers and sellers sometimes mix the two up.

Start with what your lease says

Most commercial leases contain a clause about assigning or subletting. Read it closely before you agree to any sale terms.

Also read amendments, renewals and any earlier correspondence with the landlord. They can change the picture.

When consent may not be refused unreasonably, and when the lease is silent

Some leases say the landlord cannot unreasonably withhold consent. Where that wording is present, the landlord's reasons for refusing usually matter. Whether a particular reason for refusing consent is acceptable depends on the wording of your lease and your situation, so it is worth confirming with a lawyer. How this applies to your lease is a legal question.

If the lease is silent about assignment, do not assume you are free to assign or that the landlord can refuse. The answer depends on the lease as a whole and the law that applies to it, and a lawyer can confirm your position before you commit to a closing date.

If consent is refused or delayed

Making the deal conditional protects both sides. Without that condition, a buyer could be bound to a purchase with no location, or a seller could face a claim.

Related tax and registry points, and next steps

Tax can apply to the lease side of a deal. Even with a valid section 167 election, tax is still payable on a taxable lease, licence or similar supply of property. Ask your accountant how this applies.

Searches can also help. Alberta Corporate Registry searches can show registration date, owners, directors and legal addresses for a corporation, and Personal Property Registry searches can be requested at any registry agent office in Alberta.

Frequently asked questions

Can a landlord refuse to let me assign my commercial lease?

It depends on the lease wording and the law that applies. Many leases require consent, and some say it cannot be unreasonably withheld. A lawyer can tell you where you stand.

What if my lease says nothing about assignment?

Do not assume either way. The result depends on the whole lease and applicable law. Have a lawyer review it before you set a closing date.

Does a share sale avoid the need for consent?

Not always. Some leases treat a change of control as an assignment. Check the lease wording for this before you choose a deal structure.

Does GST apply to a commercial lease in a business sale?

Even with a valid section 167 election, tax is still payable on a taxable lease, licence or similar supply of property. An accountant can confirm how this applies to your deal.
