You’ve built your business from the ground up in this location. The foot traffic is perfect, your customers know where to find you, and moving would be a nightmare. Then you open your commercial lease and realize – your renewal clause is buried in fine print, full of phrases like ‘market rent to be mutually agreed upon’ and ‘subject to landlord’s approval.’ What does any of that actually mean for you?
The renewal clause in an Ontario commercial lease is one of the most consequential provisions a tenant will ever negotiate – yet it is also one of the most misunderstood. Unlike residential tenants, commercial tenants in Ontario enjoy very few automatic legal protections. If your lease does not contain a clear, properly worded renewal option, you could find yourself scrambling to relocate when your current term ends.
This guide walks you through everything you need to know about commercial lease renewal in Ontario – in plain English, with real-world examples and legal references – so you can walk into your next negotiation confident and prepared.

What Is a Renewal Clause in an Ontario Commercial Lease?
A renewal clause (also called a renewal option or option to renew) is a contractual right that gives the tenant the ability to extend the lease beyond its original term, typically on pre-agreed or formula-determined conditions. Think of it as a promise from your landlord that says: ‘If you follow the rules we set out here, we will give you another term.’
Renewal clauses are not automatic. They must be negotiated, drafted into the lease, and properly exercised by the tenant within the deadlines set out in the agreement. Without a renewal clause, your landlord has no legal obligation to let you stay once your lease term ends.
Renewal clauses typically specify:
- The number of renewal options available (e.g., one option to renew for five years)
- The deadline by which the tenant must exercise the option (commonly 6 to 12 months before the current term ends)
- How the rent for the renewal term will be determined (e.g., current market rent, or a fixed increase)
- What other terms will carry forward (usually ‘same terms and conditions’ as the original lease, except rent)
- Any conditions that could invalidate the option (e.g., being in default at the time of exercise)
Are Commercial Tenants Entitled to Lease Renewal in Ontario?
The short answer is no- not automatically. This often surprises business owners who are used to hearing about tenant protections in a residential context. Ontario’s Residential Tenancies Act, 2006 provides extensive rights for apartment renters. But commercial tenants are governed primarily by their contract (the lease itself) and the Commercial Tenancies Act, R.S.O. 1990, c. L.7, which is largely silent on renewal rights.
The Commercial Tenancies Act does not grant any automatic right of renewal to a commercial tenant. If your lease expires and does not contain a renewal clause, your landlord is legally entitled to ask you to vacate or to offer you a new lease on completely different terms.
That said, courts in Ontario have recognized and enforced properly worded renewal options consistently. The key is that the option must be exercised exactly as specified in the lease and it must be sufficiently certain in its terms to be enforceable.
In 1473587 Ontario Inc. v. Jackson, the Ontario Superior Court of Justice affirmed that a renewal option is a unilateral contract right- once the tenant properly exercises it, the landlord is legally bound. However, precision in drafting matters enormously. An option that simply says ‘the parties may negotiate renewal terms’ has been held to be an agreement to agree, which is generally unenforceable under Canadian contract law.
The Most Important Terms to Negotiate in a Renewal Clause
Not all renewal clauses are created equal. Here are the provisions that can make the difference between a clause that protects your business and one that leaves you exposed.
1. Number and Length of Renewal Periods
Negotiate for as many renewal periods as your business plan requires. A single five-year term may seem like enough, but what if your business is still thriving in year four? Try to secure two or three successive renewal options. Each option is a separate right- you are not obligated to exercise any of them, but having them gives you flexibility and negotiating leverage.
2. The Notice Period and Mechanism
Be very careful about when and how your notice should be given. There are strict requirements in each clause regarding the need to give your notice in writing a certain number of months prior to the expiration of your current lease, usually six months if it is a long lease.
Your method of delivering notice will vary, depending on what is specified in your lease. Be sure you use exactly the method that is described in the lease.
3. Rent Determination Method
This is the single most contentious issue in commercial lease renewals. There are three common approaches:
- Fixed increase: Rent increases by a specified percentage or fixed dollar amount. This is the most tenant-friendly option- it provides certainty.
- Tied to Consumer Price Index (CPI): Rent adjusts based on Statistics Canada’s CPI data. This is reasonably predictable but can rise unexpectedly during inflationary periods.
- Fair Market Rent (FMR): Rent is reset to whatever the prevailing market rate is at the time of renewal. This is the most common and most dangerous option for tenants, as we discuss below.
4. Carry-Forward Terms
Many renewal provisions will state something like this: “renewal on same terms and conditions as original lease except rent.” It is important to know exactly what that provision encompasses. Is your existing tenant improvement allowance still applicable? Your exclusivity provision? Your parking provision or signage rights? These provisions must be spelled out in your renewal clause.
5. Conditions on the Right to Renew
Many renewal clauses are conditional the tenant must not be in default of the lease at the time the option is exercised. This is generally reasonable, but watch for overly broad default clauses that could be triggered by technical or minor breaches. Negotiate for a cure period before the right is lost.

Common Problems Hidden in Commercial Lease Renewal Clauses
Even experienced business owners are often caught off guard by clauses that appear straightforward but contain hidden traps. Here are the most common pitfalls our clients encounter.
‘Agreement to Agree’ Language
Terms such as “the rent shall be mutually agreed” or “the parties will negotiate in good faith” seem to make sense, but they actually pose problems in law. The Canadian courts have always been consistent in ruling that an agreement to agree upon a material term (such as rental costs) cannot be considered a binding contract.
Empress Towers Ltd. v. Bank of Nova Scotia, [1991] 1 SCR 659, is a Supreme Court of Canada decision dealing with a provision for renewal that hinges on negotiations in the future, highlighting the need for certainty in the clause. Although this was related to a bank’s lease, Ontario commercial courts often rely on the same logic.
Personal Guarantee of Renewal
Some landlords try to require the renewal to be personally guaranteed even when the original lease was signed by a corporation. This significantly increases the personal liability of the tenant’s principals. Push back on this or at minimum cap the personal guarantee to a defined period.
Demolition or Renovation Carve-Outs
Watch for clauses that allow the landlord to terminate the lease or refuse renewal if the building is to be ‘substantially renovated or demolished.’ These provisions can nullify your renewal option entirely, particularly in older buildings or rapidly developing urban areas.
Assignment Restrictions on Renewal
If you plan to sell your business, be aware that some leases provide that the renewal option is personal to the named tenant and cannot be assigned or transferred to a purchaser. This can dramatically reduce the value of your business to a prospective buyer.

How Renewal Rent Is Determined in Ontario Commercial Leases
For many Ontario commercial tenants, the rent payable during the renewal term is the biggest financial unknown. When a lease specifies ‘fair market rent’ or ‘current market rate,’ this can lead to significant uncertainty – and in hot commercial real estate markets, a shocking rent increase.
What Is Fair Market Rent?
Fair market rent (FMR) is generally defined as the rent that a willing landlord and a willing tenant, both knowledgeable and acting without compulsion, would agree upon for the space in the open market at the time of renewal.
In practice, determining FMR involves comparing the space to similar commercial units in the same area – taking into account location, size, condition, permitted use, and other relevant factors. The problem is that this is inherently subjective, and landlords and tenants often disagree dramatically on what the market is saying.
Real-World Example
The owner of a café in Toronto signs a five-year lease in 2018 for $45 per square foot. However, she has a rental adjustment clause stating that her rent will be adjusted to ‘current market rent’ when the time comes to renew. Unfortunately, the rents in her neighbourhood increase to $75 per square foot by 2023 – a 67 percent increase.
Dispute Resolution Mechanisms
Well-drafted renewal clauses include a mechanism for resolving rent disputes. The most common approaches are:
- Binding Arbitration: Parties agree to submit to a neutral arbitrator who determines FMR. This is fast and confidential.
- Appraisal: Each party retains a qualified commercial appraiser; if they cannot agree, the two appraisers appoint a third whose determination is binding.
- Baseball Arbitration: Each side submits a number; the arbitrator must choose one or the other (no splitting the difference). This encourages both parties to be reasonable.
Without a dispute resolution mechanism, the parties are left to litigate in court – a slow, expensive process that benefits no one.
Ontario courts have addressed FMR disputes in cases like Peel (Regional Municipality) v. Great Atlantic & Pacific Co. of Canada Ltd. (1990), 74 OR (2d) 164 (CA), which affirmed that courts may look to comparable lease transactions, expert evidence, and the specific characteristics of the premises when determining fair market rent in the absence of agreement.
Negotiating a Rent Cap
One of the most powerful tools that a tenant can use is to negotiate for a rental increase cap when renewing the lease. For instance, it can say that the rent upon renewal should be the lower of (i) market rate rent, or (ii) the base rent for the last year of the previous term plus 10%.

What Happens If a Tenant Misses the Renewal Deadline?
Missing the renewal deadline is one of the most devastating – and preventable – mistakes a commercial tenant can make. In most cases, a missed deadline means the renewal option is permanently lost, regardless of the reason.
That being said, there are rare occasions where the courts can act:
- Waiver: Where actions by the landlord show that the deadline has been accepted (such as acceptance of rental payment beyond the deadline date), then the landlord is considered to have waived their rights.
- Estoppel: Where representations have been made by the landlord that have resulted in the tenant believing that enforcement will not occur, an argument based on estoppel may be successful.
- Equitable Remedy: On rare occasions, a court might grant a remedy against forfeiture of the lease through the Commercial Tenancies Act.
Practical Steps to Protect Yourself
- Put the renewal deadline in your calendar the day you sign the lease – with multiple advance reminders.
- Appoint a specific person in your organization (or your lawyer) to be responsible for monitoring the renewal deadline.
- Send renewal notice by a method that creates a paper trail – registered mail, courier, or signed acknowledgment.
- Review your lease annually to ensure no changes to the required notice method have occurred.

Negotiation Strategies for Ontario Commercial Tenants
Many tenants assume the lease presented by the landlord is non-negotiable. This is almost never true – especially in a tenant’s market or for longer lease terms. Here are strategies that actually work.
Start Early – Before You Need to Renew
The best time to negotiate your renewal terms is before you sign the original lease. A renewal clause negotiated at the outset, when the landlord is motivated to fill the space, is almost always more favourable than one negotiated close to the renewal date, when the landlord knows you are invested in staying.
Know the Market
Before entering into negotiations, make sure that you know what kinds of leases similar to yours look like. This information is obtainable from commercial real estate agents, who have access to commercial listings provided by most local authorities.
Tie Rent to an Objective Formula
Push for a rent determination formula that is as objective as possible – a fixed percentage increase, a CPI index, or a formula with a defined cap. The more objective the formula, the less room for dispute.
Negotiate Multiple Options
Every additional renewal option you secure is future leverage. Even if you are not sure you will want a third five-year term, having the option costs you little and gives you negotiating currency – particularly if you are later selling the business.
Get Professional Help
A commercial real estate broker and a commercial lease lawyer are not luxuries – they are investments. Brokers negotiate commercial leases daily and know what landlords will and will not accept. Lawyers ensure the clause is legally sound and that the rights you negotiated are actually enforceable as written.

Landlord Perspective: Why Renewal Clauses Matter to Property Owners
Understanding what matters to your landlord can make you a better negotiator. Landlords are not simply adversaries – they have legitimate business interests that, when understood, can inform creative compromise.
Predictability of Income
Landlords typically have a preference for tenants who stay longer compared to leaving the space empty. Tenants who are already in a landlord’s possession and who have been there before are far much safer than the expenses involved in securing new tenants. Thus, most landlords would accept reasonable terms of renewal if directly asked.
Property Valuation
Commercial property values are calculated through rental income. Property with long-standing tenants is more valuable than those with many turnovers. Reasonable renewal terms can be offered by landlords because having good tenants contributes positively towards the value of their investment.
Redevelopment Plans
On the other hand, landlords who are planning to sell, refinance, or redevelop the property may be resistant to long renewal terms that tie up the property. In these situations, a tenant’s renewal option can be a complicating factor in the landlord’s plans – which is exactly why having it in writing is so valuable.
When to Hire a Commercial Lease Lawyer in Ontario
Many tenants try to handle commercial lease negotiations on their own or rely on a real estate agent to review the legal provisions. While agents are invaluable for market knowledge, they are not lawyers and cannot provide legal advice on the enforceability or interpretation of lease clauses.
You should consult a commercial lease lawyer in Ontario when:
- You are signing any new commercial lease, regardless of length
- You are approaching a renewal date and are unclear about your rights or obligations
- Your landlord is proposing material changes to the lease on renewal
- A dispute has arisen over the amount of renewal rent
- You missed a renewal deadline and want to understand your options
- You are selling your business and need to confirm that your renewal rights are assignable
- Your lease contains an arbitration or appraisal clause and you need representation in that process
Ontario commercial lease lawyers can help you understand your existing rights, draft or review renewal clauses, negotiate directly with landlords or their counsel, represent you in arbitration or mediation proceedings, and advise on remedies if a landlord breaches a renewal agreement.
Frequently Asked Questions
1. What is a renewal option in a commercial lease?
A lease extension is an option that is embedded into the lease contract allowing the tenant to extend the lease period under certain terms. It is important to note that the lease extension option does not automatically come into force; the tenant must act by notifying the landlord about their decision before a deadline indicated in the contract expires. In this way, the landlord will have no legal grounds to refuse a new lease.
2. Can a commercial landlord increase rent during renewal?
Yes – in most cases, commercial landlords can increase rent at renewal. The amount of the increase, and whether it is permitted, depends entirely on what your renewal clause says. If the clause specifies a fixed increase or a formula, both parties are bound by it. If the clause calls for ‘fair market rent,’ the rent can increase significantly. A well-negotiated clause will include a cap on increases or an objective formula that limits the landlord’s ability to impose a dramatic hike.
3. How much notice is required to renew a commercial lease in Ontario?
There is no standard legal requirement – the required notice period is set out in your individual lease. Most commercial leases require notice between 3 and 12 months before the end of the current term, with 6 months being the most common. Some longer leases (10+ years) may require up to 12 months’ notice. Read your lease carefully, diarize the deadline, and always give notice in writing by the method specified in the agreement.
4. What happens if renewal rent cannot be agreed upon?
If your lease contains a dispute resolution mechanism (such as arbitration or appraisal), that process will be used to determine rent. If there is no mechanism, the parties must either negotiate a resolution or litigate the matter in court. This is precisely why including an objective rent formula or a clear dispute resolution process in the original lease is so important. Without it, a disagreement over renewal rent can become very expensive for both sides.
5. Can a landlord terminate after a renewal option is exercised?
No, not usually. Once a tenant exercises his/her renewal option properly and the landlord accepts it, then that creates an enforceable agreement. The landlord can’t just change his mind about this. But if the landlord does have a termination right within the lease, for example a demolition or redevelopment clause, then there are some situations where this will override the renewal option. Have a lawyer check out any conflicting clauses in your lease.
6. Is market rent determined by appraisal?
This will depend on your lease. In case your renewal provision includes an appraisal method, then yes, each side can appoint a certified commercial appraiser, and if there is disagreement between the two, they can bring in another third-party appraiser. However, if the lease provides a market rent and nothing else, then the matter will have to be settled by agreement or determined by a court/arbiter using similar comparable market information. In an Ontario court, appraisal evidence would be the key to determining fair market rent.
7. Can tenants negotiate renewal rights after signing the lease?
Yes, but it is more difficult. If you did not include a renewal clause when you first signed, you can still negotiate one through a lease amendment. Your ability to do so depends on your landlord’s willingness and your leverage as a tenant (how desirable you are, how long you have been there, how difficult you would be to replace). It is always best to negotiate renewal rights before signing, but it is not impossible to add them later – especially if you have a strong track record and the landlord values your tenancy.
8. What is the difference between a renewal and an extension?
The two terms are often used synonymously, but there is an actual legal difference between them. In most cases, a renewal refers to the creation of a new lease according to particular terms that take effect after the expiration of the old terms. Extension implies that the old lease extends further past its initial term end, usually under the same conditions. This distinction has a legal implication in that some time limits will be extended if it is a renewal, but may not be in case of an extension.
