The Most Important Commercial Lease Terms for Business Owners
Signing a commercial lease is one of the biggest financial commitments a founder will ever make. Whether you are opening your first studio, expanding an office, or setting up a clinic, it is essential to understand one fundamental reality: commercial leases in Canada are governed by contract law, not residential tenant protections.
There are no standard rent-increase caps or automatic tenant rights provided for commercial tenants. What is written in your commercial lease agreement is generally what holds up in court.
As a business owner (and commercial tenant) the terms you agree to upfront will set the tone for your tenancy over multiple years or even decades, that’s why it’s important to take the time to understand what youre agreeing to and negotiate lease terms that will enable your business to grow and thrive. Channel your inner CEO, this is not the time to be polite and quiet.
Negotiating favourable lease terms can protect your cash flow, your operating rights, and set your business up for success. Below I’ve compiled for you a list of the most important commercial lease terms business owners should be aware of. Depending on your business and goals, some may be more important for you than others.
1. Financial Terms: Base Rent vs. Additional Rent
If you’ve been closely eyeing commercial real estate listings, you may have realized that the advertised price is almost never your total monthly cost. Translation: prepare your bank account for a surprise plot twist.
Base Rent (Basic Rent): This is the fixed cost paid to occupy the space, usually calculated on a per-square-foot annual basis.
Additional Rent (Triple Net / NNN): This is your (the tenant’s) proportionate share of the building’s operating expenses. This includes real estate taxes, building insurance, and Common Area Maintenance (CAM) like heating shared spaces, snow removal, and security.
Pro Tip for Founders: Additional Rent can easily add 30% to 50% on top of your Base Rent. Make sure to budget accordingly.
2. Operational Terms: Permitted Use & Exclusivity
Property owners usually curate the mix of tenants in commercial properties to protect building value. That’s why you may see some commercial spaces that cater primarily to franchises while others cater to professional services.
Permitted Use: This dictates exactly what business activities, products, or services you can operate on-site. If your clause specifies "accounting office," you cannot legally pivot to running public events or selling retail goods without written permission.
Exclusivity Clause: This refers to a tenant-friendly term where the landlord agrees not to lease any other unit in the building to your direct competitor.
Pro Tip for Founders: Negotiate keeping your Permitted Use clause as broad as possible to give your business room to pivot or expand product lines over time.
3. Timeline Terms: Initial Term & Options to Renew
Balancing stability with flexibility is key when committing to a commercial footprint. Many founders think that getting into a shorter lease is better, especially if their business is new, but that means you may have to later renegotiate to stay in the space (often with less leverage than you had at the beginning).
Initial Term: The fixed duration of your lease (typically 3, 5, or 10 years).
Option to Renew: A contractual right that gives you the right to extend your lease for an additional period before the initial term ends.
Pro Tip for Founders: Options to renew are not automatic. They require strict written notice delivered within a specific window, usually 6 to 9 months before expiry.
4. Maintenance & Repairs: Demised Premises vs. HVAC
Pay close attention to where your maintenance obligations begin and end, as the tenant. This surprises many new founders, but commercial leases often have costly maintenance obligations for tenants (yes, that means more costs $$$).
Demised Premises: The specific interior space leased exclusively to your business.
Utility Systems (HVAC): Standard landlord drafts often make tenants responsible for the ongoing maintenance, repair, and sometimes full replacement of utility systems (like heating and cooling units) serving their space.
Pro Tip for Founders: Always review these lease clauses carefully, and wherever possible negotiate a cap on your maintenance exposure.
5. Exit & Risk Clauses: Demolition & Relocation
Sometimes, lease agreements include some high-risk clauses can interrupt your business even if you pay rent on time. As a lawyer, some of the first terms I search for when reviewing my client’s commercial leases are “demolition” and “relocation.” Consider this your official permission to be high-maintenance about the fine print.
Demolition / Redevelopment Clause: This clause allows the landlord to terminate your lease early if they decide to demolish or redevelop the building.
Relocation Clause: This gives the landlord the right to move your business to another unit within the property at their discretion.
This list of important lease terms to know is not exhaustive, there are many more terms to know and look out for in a lease. However, these terms are what I consider to be the most consequential for most of my clients. Once I get to know my client, their business and goals, I can recommend which lease terms are the best to negotiate. Negotiating lease agreement is a highly strategic exercise and one that I’m happy to support clients in for a variety of businesses including: counsellling practices, fitness studios, med spas, beauty salons, and more.
Signing and negotiating a commercial lease is a big step and doing it with guidance from a legal professional can make a tremendous difference. If you’re looking for support with your commercial lease in Canada, book your call with me to discuss your lease.
