Commercial leases are fundamentally different from residential leases — they are not governed by the Residential Tenancies Act, are far more negotiable, and can be significantly longer in duration. For Ontario property owners leasing commercial space, getting the terms right protects your investment for five, ten, or fifteen years. Here is what experienced commercial landlords focus on during negotiations.

Understand the Different Commercial Lease Structures

Before negotiating terms, understand what type of lease you are negotiating. The structure determines who pays what operating costs:

• Gross Lease: The tenant pays a fixed rent and the landlord covers all operating costs (taxes, insurance, maintenance). Simple for tenants, risk-bearing for landlords if costs rise.
• Net Lease (Single, Double, or Triple Net): The tenant pays base rent plus some or all operating costs. A Triple Net (NNN) lease passes property taxes, insurance, and maintenance to the tenant — the preferred structure for long-term commercial landlords.
• Modified Gross Lease: A hybrid — tenant pays base rent plus specific agreed-upon expenses. Common in multi-tenant office buildings.
• Percentage Lease: Base rent plus a percentage of tenant revenue. Common in retail, particularly for anchor tenants in plazas.

Most sophisticated commercial landlords in Ontario prefer net lease structures because they protect against operating cost inflation while still attracting quality tenants with competitive base rents.

Key Clauses to Negotiate in Your Favour

Commercial leases are highly negotiable — unlike residential leases with prescribed forms. Focus attention on these critical provisions:

• Rent escalation: Build in annual rent increases tied to CPI or a fixed percentage (2–3% per year). Avoid flat rent for multi-year terms.
• Permitted use clause: Define what the tenant can use the space for specifically. A broad permitted use clause reduces your control and can complicate future leasing if use conflicts arise.
• Assignment and subletting: Require landlord consent for assignments and sublets. This prevents tenants from placing unqualified occupants in your space.
• Renewal options: Be cautious about granting renewal options at below-market rates. Include provisions to set renewal rent at market or use an agreed formula.
• Personal guarantee: For smaller businesses or new tenancies, require a personal guarantee from the principal of the tenant company. This prevents tenants from walking away by dissolving the operating corporation.
• Demolition and redevelopment clause: If long-term redevelopment is a possibility, include a demolition clause permitting termination with appropriate notice.

Tenant Improvement Allowances (TI)

In competitive commercial markets, landlords often provide a tenant improvement (TI) allowance — a contribution toward the cost of fitting out the space for the tenant's use. TI allowances are a key negotiating lever: tenants want them as large as possible; landlords want to minimize upfront cash outlay while still attracting quality tenants.

Structure TI allowances carefully. Tie disbursement to lease execution and completion of improvements, require receipts and contractor documentation, and ensure improvements remain with the building (tenant cannot remove them). The allowance effectively becomes embedded in the economics of the long-term lease — factor it into your overall return calculation.

Due Diligence on Prospective Commercial Tenants

Commercial tenant screening is different from residential screening. Evaluate the business — not just the individual. Review financial statements, corporate credit checks, business history, industry outlook, and the quality of their management. A 10-year lease with a company that is financially precarious is worse than a 3-year lease with a financially stable tenant.

Request two to three years of financial statements or tax returns. Evaluate revenue trends, debt load, and profitability. If the business is new, the financial strength of the personal guarantor becomes paramount.

Frequently Asked Questions

How long are commercial leases typically in Ontario?

Commercial leases in Ontario commonly range from 3 to 10 years for smaller tenants, and 10–25 years for large anchor tenants. Longer leases provide rent certainty but reduce flexibility for both parties.

Is there a standard commercial lease form in Ontario?

No. Unlike residential tenancies, commercial leases have no mandated form. Each lease is individually negotiated, which is why having experienced legal counsel review commercial lease terms is important for both parties.

Can I evict a commercial tenant for non-payment?

Commercial landlords have the right to distrain (seize goods on the premises) and terminate the lease for non-payment, but the process differs from residential evictions. Commercial lease enforcement is governed by contract law and the Commercial Tenancies Act. Legal counsel is strongly recommended.
