Commercial Lease Renewals in Ontario: What Business Owners Need to Know

- 4 min read
For many businesses, the commercial lease becomes one of the most valuable assets supporting operations. Customers know the location, employees are familiar with the space, and significant investments may have been made in improvements, signage, equipment, and branding.

As the lease term approaches expiration, many business owners assume renewal will be straightforward. However, commercial lease renewals often create some of the most important legal and financial decisions a tenant will face.
Understanding renewal rights, notice requirements, rent calculations, and negotiation opportunities can help protect your business and avoid costly surprises.
Do Commercial Tenants Have an Automatic Right to Renew?
One of the most common misconceptions is that commercial tenants automatically have the right to renew their lease.
In most cases, they do not.
Commercial lease renewal rights are typically governed by the lease agreement itself.
If the lease contains a renewal option, the tenant may have the ability to extend the term by following the requirements set out in the lease.
If no renewal provision exists, the landlord is generally not obligated to offer a new lease.
This makes the renewal language one of the most important provisions to review before signing the original lease.
Understanding Renewal Options
A renewal option gives the tenant the right to extend the lease for an additional period, subject to the conditions outlined in the agreement.
Renewal clauses commonly address:
• Length of the renewal term
• Number of available renewals
• Notice deadlines
• Rent calculation methods
• Conditions that must be satisfied before renewal can occur
Even where a renewal option exists, tenants must carefully follow the lease requirements to preserve their rights.
Missing a Renewal Deadline Can Be Costly
Many commercial leases require tenants to provide written notice of renewal several months before the lease expires.
If the notice period is missed, the renewal right may be lost.
This can create significant problems for businesses that:
• Depend on a specific location
• Have invested heavily in leasehold improvements
• Serve an established customer base
• Face relocation costs
Tracking critical lease deadlines is essential.
How Is Rent Determined During Renewal?
One of the most important aspects of a lease renewal is the new rent amount.
Commercial leases commonly use one of the following approaches:
Fixed Rent Increases
The lease specifies the rent that will apply during the renewal period or establishes predetermined increases.
This approach provides certainty and predictability.
Market Rent
Many renewal clauses require the parties to negotiate market rent at the time of renewal.
While common, market rent provisions can create uncertainty and disputes if the lease does not clearly define how market rent will be determined.
Appraisal Processes
Some leases provide a mechanism for independent appraisers to determine market rent if the parties cannot agree.
Understanding these provisions before renewal discussions begin is critical.
Renewal Is Often an Opportunity to Renegotiate
Business owners sometimes assume that only rent can change during a renewal.
In reality, lease renewals often create an opportunity to discuss:
• Rent structure
• Additional rent provisions
• Maintenance obligations
• Renewal rights
• Assignment and subleasing rights
• Personal guarantees
Depending on the circumstances, tenants may be able to negotiate more favorable terms than those contained in the original lease.
What If the Lease Does Not Contain a Renewal Option?
If a lease does not provide a renewal right, the tenant may still be able to negotiate a new lease with the landlord.
However, the landlord is generally under no obligation to offer the same terms.
This may result in:
• Higher rent
• Different lease conditions
• Shorter terms
• Additional security requirements
• Personal guarantees
The tenant's leverage often depends on market conditions and the desirability of the premises.
Why Business Owners Should Start Early
One of the most common mistakes tenants make is waiting until the lease is about to expire before reviewing their options.
Beginning the process early provides time to:
• Review the lease
• Assess business needs
• Negotiate terms
• Explore alternative locations if necessary
• Preserve renewal rights
Early planning often leads to stronger negotiating positions and better outcomes.
Common Renewal Mistakes
Business owners frequently encounter problems when they:
• Miss renewal deadlines
• Assume renewal is automatic
• Fail to review rent adjustment provisions
• Ignore personal guarantee requirements
• Overlook changes in operating costs
• Delay negotiations until the last minute
Avoiding these mistakes can significantly reduce risk and uncertainty.
Why Legal Review Matters
Commercial lease renewals can affect a business for years.
A lease review can help identify:
• Renewal deadlines
• Rent escalation risks
• Problematic clauses
• Negotiation opportunities
• Potential liabilities
Understanding these issues before exercising a renewal option can help protect both the business and its long-term financial stability.
Book a Consultation
If your commercial lease is approaching renewal, you are considering exercising a renewal option, or you want to understand your rights before negotiating with your landlord, you can Book a Consultation to review the lease and discuss your options.
