Commercial Lease Review & Negotiation

A commercial lease is one of the most significant contracts a business will ever enter into. Whether you are a landlord investing in commercial property or a business owner leasing your first commercial space, the terms of the lease will govern your rights and obligations for years — sometimes decades — to come. A poorly drafted or one-sided lease can expose you to significant financial and operational risk. At Goldstone Law Professional Corporation, we provide experienced commercial lease review, drafting, and negotiation services to landlords and tenants throughout Ontario.

Ontario’s Commercial Tenancies Act

Commercial leases in Ontario are governed primarily by the Commercial Tenancies Act and the parties’ own contract. Unlike residential tenancies, commercial tenancies offer far less statutory protection for tenants — the parties are largely free to negotiate their own terms, subject to certain statutory minimums. This makes careful contract review and skilled negotiation all the more important. A commercial tenant who signs a standard form lease without legal review may be agreeing to terms that could significantly limit their operational flexibility, expose them to disproportionate maintenance obligations, or prevent them from subletting or assigning the lease if their business circumstances change.

Types of Commercial Leases

Gross Leases

In a gross lease, the tenant pays a fixed monthly rent, and the landlord covers most operating costs, including property taxes, insurance, and maintenance. Gross leases are simpler for tenants to budget but are less common in the Ontario commercial market.

Net Leases

Net leases require the tenant to pay base rent plus some or all of the operating costs of the property. In a triple net (NNN) lease — common in retail and industrial settings — the tenant pays base rent plus property taxes, building insurance, and maintenance costs. These additional costs (often called additional rent or CAM charges) can represent a substantial financial obligation and require careful review.

Percentage Leases

Percentage leases, common in retail settings such as shopping malls, combine a base rent with a percentage of the tenant’s gross sales. The drafting of the gross sales definition, reporting obligations, and audit rights in a percentage lease requires careful attention.

Key Lease Provisions We Review and Negotiate

• Base rent amount, escalation clauses, and rent review mechanisms
• Additional rent / CAM charges — scope, caps, and audit rights
• Permitted use clause — ensuring sufficient flexibility for your business activities
• Maintenance and repair obligations — division between landlord and tenant
• Leasehold improvement provisions and tenant inducement allowances
• Assignment and subletting rights — critical for business flexibility
• Options to renew — terms, notice requirements, and rent determination
• Early termination rights and conditions
• Insurance requirements and indemnification provisions
• Personal guarantee requirements and personal liability exposure
• Default and remedies — notice periods and cure rights
• Exclusivity clauses for retail tenants

We also advise on the practical commercial implications of lease terms — not just their legal validity. A lease term that is legally enforceable may still be commercially unacceptable. Our goal is to ensure that the final lease accurately reflects the commercial deal you negotiated and provides you with the operational flexibility your business requires.

Lease Renewals and Amendments

Many tenants approach lease renewal as a routine administrative step. In fact, a lease renewal is an opportunity to renegotiate key terms — particularly if market conditions have changed since the original lease was signed. We assist tenants and landlords with lease renewals and amendments, ensuring that the agreed-upon changes are properly documented and legally enforceable.

Frequently Asked Questions — Commercial Lease Review & Negotiation

Should I have a lawyer review my commercial lease before signing?

Absolutely. Commercial leases are lengthy, complex documents that are written to protect the landlord’s interests. Having a lawyer review the lease before you sign can identify provisions that expose you to financial risk, limit your operational flexibility, or contradict what you agreed to verbally with the landlord. The cost of legal review is minimal compared to the financial exposure of a problematic lease.

Can I negotiate the terms of a commercial lease in Ontario?

Yes. Unlike residential leases, commercial leases are fully negotiable between the parties. Landlords often expect tenants to negotiate, and a well-represented tenant can often secure meaningful improvements to the standard form lease, including rent concessions, leasehold improvement allowances, assignment rights, and renewal options.
