Your Landlord Is Selling the Building. Is Your Commercial Lease Protected?

You’ve just learned that the building your business occupies is being sold. You have several years remaining on your lease, you’ve invested in your space, and you have no intention of moving. 

Should you be concerned? 

A change in ownership doesn’t automatically mean trouble for commercial tenants. In many cases, business continues as usual. However, a property sale is a good reason to review your lease, particularly the rights you’ve negotiated and whether they’re adequately protected. 

The important question isn’t simply whether your lease will continue. It’s whether all the protections you’re counting on will remain enforceable when the property changes hands. 

What Happens to Your Lease When a Building Is Sold?

Generally, a commercial property can be sold while tenants continue occupying their premises under existing leases. As a general rule, a purchaser who acquires a building subject to an enforceable lease steps into the landlord’s position and becomes bound by the lease obligations that relate to the property.

However, tenants shouldn’t assume every contractual right will automatically be enforceable against a purchaser. Promises that are personal to the original landlord, such as certain side agreements, rent inducements, or unpaid leasehold improvement allowances, may not bind the new owner.

The outcome can depend on provincial legislation, the terms of your lease, whether it has been registered on title, and the priority of other interests affecting the property. 

This is particularly important for businesses that have invested heavily in their premises or depend on a specific location. 

What Could Change Under New Ownership? 

Even when your lease remains in place, a new landlord may introduce changes to property management, maintenance programs, billing procedures, or building operations. 

Some changes may be positive, such as improved facilities or more responsive management. Others may require closer attention, particularly if the new owner has redevelopment plans or different priorities for the property. 

A change in ownership is also an opportunity to confirm that the new landlord has complete copies of your lease, amendments, and other relevant agreements. 

The Lease Rights You Shouldn’t Take for Granted

Commercial leases often contain valuable protections beyond the right to occupy a space. 

These may include: 

• Renewal options: The ability to extend your occupancy, particularly important when relocation would be costly or disruptive. 
• Exclusivity provisions: Restrictions on competing uses within a shopping centre or property. 
• Purchase rights: Rights of first refusal or options to purchase the premises. These rights deserve special attention, because the sale itself may trigger them, often with short response deadlines.
• Expansion rights: Opportunities to secure additional space as your business grows. 

These provisions can have significant commercial value, but they are not equally secure. Their enforceability against a subsequent owner depends on how they’re documented, registered, and prioritized. 

Is Your Commercial Lease Registered?

This is one of the most important questions tenants should ask, ideally when the lease is signed rather than when a sale is announced. Many leases prohibit registration of the full lease but permit registration of a notice of lease, and the landlord’s cooperation may be required, so check your lease for a registration clause.

Commercial lease registration generally involves recording a lease or an appropriate notice of lease in the provincial land registry. 

Registration can help protect a tenant’s interest against subsequent owners and lenders, including certain negotiated rights associated with the property. 

However, registration is not an absolute guarantee. The extent of protection depends on provincial legislation, timing, existing mortgages, and the nature of the rights involved. Some unregistered leases receive statutory protection, but these protections can differ across the Provinces.

Mortgages matter too. A lease that ranks behind an earlier registered mortgage can be at risk if the lender enforces its security. The usual protection is a subordination, non-disturbance and attornment agreement, in which the lender agrees not to disturb the tenant’s occupancy while the lease is in good standing. A purchaser’s new lender will often ask tenants to sign one as part of the sale.

The practical takeaway? Don’t assume that occupying the premises, paying rent, or having a signed lease is sufficient to protect every right you’ve negotiated.

Seven Things to Do If Your Landlord Is Selling

Whether you’ve received formal notice or simply learned that the property is being marketed, consider these steps: 

1. Review your lease. Confirm the remaining term, renewal options, notice deadlines, and any provisions relating to property transfers, demolition, relocation, or redevelopment.

2. Verify registration. Have legal counsel review the property’s title, confirm whether your lease or a notice of lease is registered, and assess whether your lease rights are adequately protected.

3. Organize your documentation. Ensure you have complete copies of your lease, amendments, landlord consents and records of any security deposit or prepaid rent, and confirm these amounts are transferred to the purchaser.

4. Understand the new owner’s plans. Establish communication with the purchaser or new property management team where appropriate. Continue paying rent to your current landlord until you receive written notice of the change in ownership and new payment instructions.

5. Revisit your leasing strategy. If expiry is approaching, assess your renewal rights and market alternatives early to preserve flexibility. 

6. Act quickly on any purchase rights. If your lease includes a right of first refusal or an option to purchase, have counsel review whether the sale has triggered it and what deadlines apply.

7. Review estoppel certificates and SNDAs before signing. Estoppel certificates confirm the status of your lease to the purchaser and/or lender. If a certificate is inaccurate, for example by confirming there are no defaults or omitting rights, you may be prevented from relying on those matters later. Have counsel review these documents before you sign.

Frequently Asked Questions

Can a new landlord terminate my commercial lease after buying the building? 

A property sale alone does not give a new owner the right to terminate an existing enforceable lease. However, many leases contain demolition, redevelopment, or relocation clauses that allow a landlord, including a new owner, to end the lease or move the tenant on notice. Registration, priority, and applicable law also affect the outcome.

Can the new owner increase my rent? 

A change in ownership does not, by itself, create an unrestricted right to increase rent under an enforceable existing lease. Rent adjustments remain subject to the lease and applicable law. 

Does my commercial lease need to be registered? 

Registration is not universally mandatory, but it can provide important protection, particularly for leases longer than three years and in Quebec. Requirements and exceptions vary by province, so obtain legal advice.

Does the sale affect my right of first refusal?

It may trigger it. If your lease gives you a right of first refusal, the landlord may be required to offer you the opportunity to match the purchaser’s offer, usually within a short deadline. Seek advice immediately if you learn of a sale.

Do I have to sign an estoppel certificate?

Many leases require tenants to deliver one on request within a set period. Sign only after confirming it accurately reflects your lease, any amendments, and any defaults or claims, because you may be bound by what it says.

Protect Your Lease Before Ownership Changes 

A building sale can be a routine transaction. For tenants, it can also reveal gaps in lease documentation or protections that have gone unexamined for years. 

You don’t need to wait for a sale announcement to review your position.
