What is an estoppel certificate in industrial real estate?
By Michael Law, Industrial Real Estate Broker · Updated June 06, 2026
Quick answer
An estoppel certificate is a signed document in which an industrial tenant confirms the current status of their lease — including the lease terms, rent amounts, any defaults, and the existence of any side agreements — to a third party such as a lender or property buyer. Tenants are typically required by their lease to provide estoppel certificates within a specified period when requested by the landlord.

What is an estoppel certificate in industrial real estate?
An estoppel certificate is a formal statement signed by a tenant that certifies certain facts about their lease as of a specific date. The document is most commonly required when a property is being sold or refinanced — the buyer or lender needs confirmation from the tenant that the lease terms are as represented by the landlord and that no undisclosed side agreements, defaults, or disputes exist. A standard industrial estoppel certificate confirms: that the lease is in full force and effect, the lease commencement and expiry dates, the current base rent and operating cost obligations, the amount of any security deposit held by the landlord, whether any free rent or rent abatement periods are outstanding, whether the landlord is in default of any lease obligation, and whether any amendments to the original lease have been made. The tenant also typically confirms that they have no claims, offsets, or defenses against the landlord as of the certificate date. The legal significance of an estoppel certificate is that once signed, the tenant is bound by its contents — they cannot later claim facts that contradict what they certified. If a tenant signs an estoppel confirming the landlord is not in default, they cannot subsequently pursue a claim for that same default against a new owner who purchased the property relying on the certificate. This estoppel effect is the source of the document's name. Most GTA industrial leases include a clause requiring the tenant to provide a completed estoppel certificate within 10 to 20 business days of a landlord's written request. Failure to provide the certificate within the required period is typically treated as a default. Some leases go further and state that if the tenant fails to respond, the landlord's proposed form of estoppel is deemed correct — a deemed estoppel provision that tenants should be aware of and push to remove during lease negotiation. From a tenant's perspective, reviewing an estoppel certificate carefully before signing is essential. The landlord will typically provide a form estoppel that is drafted in the landlord's favour — confirming terms as the landlord understands them. If the tenant disagrees with any representation in the certificate, they should note exceptions before signing. Signing without review and without noting exceptions can inadvertently waive legitimate tenant claims.

Other questions about this
Am I required to sign an estoppel certificate?
If your lease includes an estoppel certificate obligation — which most GTA industrial leases do — yes, you are contractually required to provide a completed certificate within the specified deadline when the landlord requests one. Failure to respond within the deadline is typically a default under the lease. If you have concerns about specific representations in the landlord's form certificate, you should note exceptions rather than refusing to sign.
What should I check before signing an estoppel certificate?
Before signing, verify that the lease dates, rent amounts, and operating cost figures match your records. Confirm whether there are any outstanding landlord obligations (repairs, TI reimbursements, free rent credits) that the certificate could inadvertently waive. Check whether the landlord is in default of any lease provision. If any representation in the certificate is inaccurate or disputed, note the exception in writing before signing — do not sign a certificate containing inaccurate statements.
Can I lose my lease rights by signing an estoppel certificate?
You can lose the ability to assert claims that contradict what you certified. If you sign an estoppel confirming no landlord defaults exist and that all rent is current, you cannot later pursue those same claims against a new owner who relied on your certificate. This is why careful review before signing is critical — the estoppel effect binds you to the facts as certified.

What is a right of first refusal in an industrial lease?
A right of first refusal (ROFR) in an industrial lease gives the tenant the contractual right to match any third-party offer the landlord receives on an adjacent or specified space before the landlord can lease it to someone else. It is a space-control tool that lets an expanding tenant secure future growth space without committing to it upfront.
Read →What is the difference between a base building and turnkey industrial lease?
In a base building industrial lease, the landlord delivers the premises in a shell or base condition and the tenant is responsible for completing improvements to make the space operational — often funded through a tenant improvement (TI) allowance from the landlord. In a turnkey lease, the landlord constructs or fits out the space to the tenant's specifications and delivers it ready to occupy, typically at a higher base rent.
Read →What is CAM (common area maintenance) in industrial real estate?
CAM, or common area maintenance, refers to the costs a tenant pays — on top of base rent — for the upkeep and operation of shared areas in a multi-tenant industrial building. In a typical GTA industrial net lease, CAM is one component of the operating cost recovery alongside property taxes and building insurance, and is charged on a per-square-foot basis proportional to the tenant's share of the building.
