What is an option to renew in an industrial lease?
By Michael Law, Industrial Real Estate Broker · Updated June 05, 2026
Quick answer
An option to renew is a contractual right in an industrial lease that gives the tenant the ability to extend their lease for an additional term at the end of the initial period, at a rent determined by the mechanism specified in the option clause — typically fair market value or a fixed escalation. The tenant must exercise the option in writing within a defined notice window (usually 6 to 9 months before lease expiry) or the right is waived.

What is an option to renew in an industrial lease?
An option to renew is a contractual clause in an industrial lease that gives the tenant the right — but not the obligation — to extend the lease for an additional term at the end of the initial lease period. It is one of the most valuable protections a tenant can negotiate, providing business continuity and operational stability without requiring the tenant to commit to the extended term from day one. At the time the lease is signed, the landlord grants the tenant a specified window — typically 6 to 9 months before the lease expiry date — during which the tenant must formally exercise the option by delivering written notice. If the tenant delivers notice within this window, the lease continues for the renewal term under the terms set out in the option clause. If the tenant misses the notice window, the option is typically waived and the tenant must negotiate a new lease or vacate. The option clause specifies several critical parameters: the length of the renewal term (commonly 3 or 5 years in GTA industrial leases), the number of renewal options available (one or two options is standard), the rent-setting mechanism for the renewal term, and the notice deadline. The rent mechanism is the most negotiated element — options are typically structured as either a fixed renewal rent agreed at lease signing, a rent set at fair market value as determined at the time of renewal, or a fixed escalation percentage applied to the final year rent of the initial term. Most institutional landlords in the GTA industrial market will push for a fair market value rent-setting mechanism, meaning the renewal rent is negotiated or arbitrated at the time of renewal rather than locked in advance. This protects the landlord against long-term rent compression but introduces uncertainty for the tenant. In a rising-rent environment like the GTA industrial market has experienced since 2018, fair market value clauses can result in significant rent increases at renewal — tenants who locked in at $10 to $12 per square foot net in 2018–2020 are facing renewal discussions at $17 to $20 per square foot net in 2025–2026. A well-negotiated option clause for a tenant will include a cap on the fair market value determination — for example, the renewal rent shall not exceed 110% of the last year base rent of the initial term. This protects the tenant from extreme market rent increases while preserving the landlord's ability to reset to market within a defined band. Caps are more achievable in multi-tenant buildings and with smaller regional landlords than with institutional REIT owners managing portfolio assets. Options to renew are typically personal to the original named tenant and do not automatically transfer in an assignment or sublease. If a tenant assigns their lease to an incoming occupant, the option may be extinguished or may require the landlord's specific consent to transfer. Tenants considering an assignment or corporate transaction should review their renewal option language carefully before finalizing any transfer. In a supply-constrained market like GTA industrial, the ability to remain in an existing location is operationally and financially significant. Relocation costs for an industrial tenant — including moving expenses, re-racking, IT and infrastructure reconnection, staff disruption, and potentially higher rent in a new lease — can easily exceed $15 to $30 per square foot in one-time costs. A properly structured option to renew gives the tenant leverage in renewal negotiations and a guaranteed right of continued occupancy that no competing tenant can displace.

Other questions about this
What happens if a tenant misses the option to renew deadline?
If the tenant fails to deliver written notice of renewal within the specified window — typically 6 to 9 months before lease expiry — the option is generally considered waived under Ontario commercial lease law. The tenant loses the contractual right to renew and must either negotiate a new lease directly with the landlord (without the leverage of a guaranteed renewal right) or vacate at the end of the initial term. Some leases include a strict time-of-the-essence clause that makes deadline compliance an absolute requirement with no discretion for the landlord to waive a late notice.
Can a landlord refuse to renew even if the tenant has an option?
If the option clause is properly structured and the tenant has exercised it correctly within the notice window, the landlord is contractually bound to renew the lease. A landlord cannot unilaterally refuse a properly exercised option. However, disputes can arise over the fair market value rent determination at renewal — if the parties cannot agree on renewal rent, most option clauses provide for an arbitration or appraisal mechanism to set the rate. The tenant's right to renew the occupancy itself is not contingent on agreement over the renewal rent in most well-drafted options.
How many options to renew should I negotiate in a GTA industrial lease?
Most GTA industrial tenants negotiate one or two options to renew. A single 5-year option on a 5-year initial term gives the tenant a guaranteed 10-year occupancy window. Two 5-year options on a 5-year initial term provides a 15-year occupancy ceiling — useful for tenants making significant capital investments in tenant improvements, specialized racking, or custom infrastructure. Landlords are generally willing to grant two options on longer initial terms (7 to 10 years) but may resist multiple options on shorter initial terms.

What is a sublease in industrial real estate?
A sublease in industrial real estate is an arrangement where the original tenant (the sublandlord) rents all or part of their leased space to a new occupant (the subtenant) for a period within the remaining term of the original lease. The original tenant remains liable to the landlord under the head lease; the subtenant pays rent to the original tenant, not directly to the landlord. Subleases are common in the GTA industrial market when tenants need to downsize, relocate, or shed excess space before their lease expires — and typically offer subtenants a price discount of 10–25% below comparable direct lease rates.
Read →What does triple net (NNN) mean in a commercial lease?
A triple net (NNN) lease means the tenant pays base rent plus three additional cost layers: property taxes, building insurance, and maintenance/operating costs. In GTA industrial real estate, virtually all leases are structured as triple net — the landlord collects a fixed net rent and passes all operating expenses through to the tenant, either as direct charges or as a proportionate share of the building's total operating costs. Understanding what is and is not included in the operating cost pool is one of the most important aspects of industrial lease negotiation.
Read →What is a tenant improvement allowance in an industrial lease?
A tenant improvement allowance (TI) is a cash contribution from the landlord to help the tenant build out or modify a leased space. In GTA industrial leases, TI allowances typically range from $5 to $25 per square foot depending on deal size, term length, and building vintage. The allowance is applied against the cost of approved work — office build-out, dock levellers, electrical upgrades, HVAC modifications — and is usually structured as a landlord reimbursement after construction completion, not a cash advance.
