Commercial Lease Renewals and Options to Renew in Ontario

A renewal option is a clause giving a commercial tenant the right, but generally not the obligation, to extend a lease for an additional term once the original term ends. It’s one of the most valuable clauses a tenant can negotiate into a commercial lease, because it provides security against being forced out of a location the business has invested in — building a customer base, a reputation, or specialized fit-out — while still leaving the tenant free to walk away if the space no longer makes sense.

It’s important to understand that a renewal option is not the same as an automatic renewal. Where a lease is genuinely silent on renewal, it simply ends at the end of its term, and the tenant has no special right to stay beyond whatever the landlord is willing to offer at that point. A renewal option changes that by giving the tenant a defined, enforceable right — provided the tenant follows the specific steps the option requires to exercise it.

Renewal options can also be structured as a single additional term or as a series of successive options — for example, two separate five-year renewal rights rather than one ten-year right. A series of shorter options gives the tenant more flexibility to reassess the space at each renewal point, while a single longer option offers more certainty upfront. Which structure makes more sense depends heavily on how confident the business is about its long-term space needs at the time the original lease is signed.

It’s also worth thinking about how a renewal option interacts with financing. Lenders evaluating a business, or a prospective buyer conducting due diligence, will often look closely at how much security of tenure the lease actually provides. A strong, clearly drafted renewal option can materially support a business’s valuation and its ability to secure financing, since it reduces the risk that the business could be displaced from a location its revenue depends on.

Renewal options generally specify how rent for the renewal term will be determined, and the approach varies. Some options set a specific, pre-agreed rent or a defined formula (such as the prior rent plus a fixed percentage increase) for the renewal period, which gives both sides complete certainty from the moment the lease is signed. Others set rent at “fair market rent” as of the renewal date, sometimes with a mechanism for determining that figure if the parties can’t agree — such as an appraisal process or arbitration.

A fair-market-rent renewal option can be far less predictable than it sounds, particularly in a rapidly changing rental market. Tenants who negotiate this kind of option are effectively deferring the real cost of renewal to a future negotiation, informed by market conditions that may look very different years later. Where possible, understanding exactly how “fair market rent” would be determined — and by whom — is worth clarifying at the outset, rather than discovering the mechanism only once a dispute over the number arises.

Some renewal options combine both approaches, setting a floor and ceiling around fair market rent so the renewal rent can’t fall below a certain amount or rise above another, regardless of what the market does at the time. This kind of collar can offer a useful middle ground, giving both landlord and tenant some protection against an extreme market swing in either direction by the time the renewal date actually arrives.

Renewal options almost always require the tenant to give written notice of their intention to renew within a specific window before the current term ends — commonly somewhere between three and twelve months, depending on the lease. This notice generally needs to be unconditional and delivered in the manner the lease specifies, whether that’s by registered mail, courier, or another defined method.

Courts have generally required strict compliance with the mechanics of a renewal option, meaning a notice that’s a few days late, sent to the wrong address, or missing a required element can, in some circumstances, be treated as ineffective — even where the tenant’s intention to renew was clear. Given how consequential this can be, treating the renewal deadline as a hard, non-negotiable date on the calendar — rather than something to handle whenever it becomes convenient — is one of the simplest ways to protect a valuable renewal right.

It’s also worth checking whether the lease requires the tenant to be in good standing — no outstanding defaults, for example — at the time the option is exercised. A tenant with a history of late payments could find an otherwise valid renewal notice challenged on the basis that a good-standing condition wasn’t satisfied, which is one more reason to keep the underlying lease obligations in good order as a renewal date approaches.

If a renewal deadline is missed, the tenant’s options narrow considerably, but they aren’t always gone entirely. Some leases include a grace period, and Ontario courts have sometimes granted relief against forfeiture in narrow, fact-specific circumstances where the tenant’s failure was minor and the landlord suffered no real prejudice — though this is far from guaranteed, and it’s not something to plan around in advance.

The more reliable approach is to open a conversation with the landlord as soon as a missed deadline is discovered. Many landlords, particularly with a tenant in good standing and no urgent plan to re-lease the space, are willing to negotiate a new lease or a short extension even after a formal option has technically lapsed — but this depends entirely on the landlord’s own plans and goodwill, not on any guaranteed legal right.

If the deadline was missed because of a genuine miscommunication or administrative error rather than a change of heart, documenting exactly what happened and raising it with the landlord promptly — rather than waiting and hoping the issue resolves itself — puts the tenant in the best possible position, whether that leads to the landlord honouring the option as a courtesy or to a fresh negotiation on updated terms.

Because so much rides on the wording of a renewal option, it’s worth negotiating this clause carefully at the outset of the original lease, when the tenant typically has the most leverage. Consider negotiating for more than one renewal option where the business model justifies long-term certainty, a clearly defined rent formula rather than an open-ended fair-market mechanism, and a realistic notice window that fits how far in advance the business actually plans.

It’s also worth confirming whether the renewal option survives an assignment of the lease. If the business is ever sold, or the lease transferred to a new operator, a renewal option that doesn’t clearly transfer with the lease can become a significant gap in value for a buyer — and a point worth clarifying well before any sale conversation begins.

Finally, keep a clear paper trail of everything related to the renewal — the original lease with the option clause, any correspondence about exercising it, and confirmation of delivery. Renewal disputes often come down to exactly this kind of documentation, and a tenant who can produce a clean record of having followed every required step is in a far stronger position than one relying on memory of what was sent and when.

Where a lease doesn’t include a renewal option at all, a tenant who wants to stay simply needs to negotiate a new lease or an extension before the current term ends, with no special legal entitlement to specific terms. Starting that conversation early — well before the term ends — gives both sides time to negotiate reasonably, rather than negotiating from a position of urgency in the final weeks of the lease.

Without a formal option, a tenant also loses the leverage that comes from a defined, contractual right — the landlord is free to offer whatever terms the market supports, ask for significant increases, or decline to renew at all in favour of a different tenant. This is often the clearest illustration of why negotiating a renewal option at the outset, when a tenant typically has the most bargaining power, tends to be far more effective than hoping for goodwill once the original term is running out.

If a business anticipates wanting to stay in a location long-term, it’s often worth raising the idea of a renewal option even after the original lease has been signed, particularly if the relationship with the landlord has been positive. A landlord isn’t obligated to agree, but a mid-term amendment adding a renewal right is not unusual where both sides see value in a longer-term relationship.

Whatever the current state of your lease, treating renewal planning as an ongoing part of managing the tenancy, rather than a last-minute task, tends to produce far better outcomes.
