The renewal clause is sold to the tenant as a benefit: an option to extend the lease at the end of the initial term, keeping the space and the customer base the business has built. The standard form delivers the option in name. It often does not deliver it in practice.

Most standard-form renewal clauses give the tenant a right to renew on the same terms as the initial lease, except for rent. Rent for the renewal term is “to be agreed between the parties” or “at the then-prevailing market rent as determined by the Landlord.” Either phrase puts the rent number in the landlord's hands. The tenant has an option to renew at a rent the landlord chooses, one of the three negotiable terms broken down in the renewal clause checklist.

The exercise mechanics matter equally. The standard clause requires written notice, in a specific form, delivered to a specific address, within a specific window, and treats any defect as a waiver of the renewal right. A notice sent two weeks late, or sent to the property manager instead of the address listed in the clause, terminates the option.

Where the standard form quietly favours the landlord.

Three positions inside the standard renewal clause carry most of the operating risk for the tenant.

The rent reset.

“Then-prevailing market rent as determined by the Landlord” is not a fair-market reset. It is the landlord's number. The tenant has no defined challenge mechanism, no third-party determination, no anchor to comparable transactions. The renewal works only at the rent the landlord names.

The exercise mechanics.

Strict form requirements, written notice, a specific address, a narrow window, turn the renewal into a trap. An owner running the business does not always track the lease end date 12 months out. A missed notice converts the renewal option into a forced relocation.

The landlord's outs.

Many standard clauses condition the renewal on the tenant being in good standing, on the premises being in good condition, on the corporate tenant remaining unchanged. Each condition gives the landlord grounds to refuse the renewal on technical or selective interpretation.

Three structural moves that restore tenant control.

1. Fixed or capped renewal rent.

The strongest version: renewal rent is set in the lease at a defined dollar amount, typically expressed as a percentage uplift on the initial-term rent (for example, initial rent plus 12 percent for the five-year renewal). The tenant knows the renewal cost going in and can plan around it. The softer version: a cap on the rent increase, so renewal rent cannot exceed the initial-term rent by more than a stated percentage. Both work better than “to be agreed.”

2. A defined fair-market reset mechanism.

If a fixed or capped rent is not negotiable, define how “market rent” is determined: a list of independent appraisers, comparable transactions within a defined geographic radius, or a baseball-arbitration process where each party submits a number and the appraiser picks one. The tenant has a procedure to push back on, not just the landlord's number.

3. Forgiving exercise mechanics.

A renewal that survives small notice defects is a renewal the tenant can actually exercise. The negotiated version adds a cure period for technical defects in the notice, alternative addresses for delivery, or an evergreen provision that automatically renews unless the tenant gives notice not to renew. At minimum, extend the notice window to give the tenant more time to track and exercise.

What to ask before signing.

An Ontario business owner reviewing a renewal clause should be able to answer four questions.

  • How is the renewal rent determined? Fixed dollar amount, capped percentage uplift, or fair-market reset by a defined procedure. Not “to be agreed.”
  • When do I have to exercise? Confirm the notice window opens early enough to allow planning (12 months out is standard) and the window is at least 60 days wide.
  • What can the landlord use to refuse? Confirm the renewal conditions are objective and curable. “Tenant in good standing” needs a definition; “good condition” needs a standard.
  • What is the diary entry today? Set a calendar reminder for the renewal notice date the moment the lease is signed. The clause is only as useful as the date the owner remembers it.

DRG Law reviews commercial lease renewal clauses for Ontario business owners before signing, and helps owners exercise renewal options when the date comes.
