Mississauga Industrial Lease Structures in 2026: Understanding Net Rent, TMI, and CAM in the GTA's Largest Market

Why Lease Structure Matters as Much as the Rent Number

In Mississauga's industrial market, the headline net rent figure is almost never the whole story. A tenant signing at $14.00 per square foot net might be paying $20.00 or more per square foot in total occupancy costs once TMI, CAM, utilities, and other pass-throughs are factored in. For investors underwriting an acquisition, misreading these components can materially distort your NOI projection and, by extension, your valuation.

Mississauga is the GTA's largest and most liquid industrial submarket — roughly 170 million square feet of inventory spread across corridors like Airport Road, Dixie/Matheson, Hurontario, and the 401/410 interchange zone. With that scale comes significant variation in how leases are structured, what landlords are pushing for in 2026, and what tenants can realistically negotiate. This article breaks down the mechanics.

The Net Lease Framework: What You're Actually Signing

Virtually all industrial leases in Mississauga are structured as triple-net (NNN) or net-net-net leases. The tenant pays a base (net) rent to the landlord, and separately reimburses the landlord for operating expenses. This is the standard in Ontario industrial real estate, and deviating from it is rare outside of smaller legacy buildings or owner-user arrangements.

The three core components of a Mississauga industrial lease:

1. Net Rent (Base Rent)

This is the landlord's return — the amount that flows to the ownership entity before expenses. In 2026, Mississauga net rents by corridor look roughly like this:

• Airport Road / Airport Corporate Centre: $16.00–$20.00 PSF (Class A, high-image)
• Dixie Road / Matheson Blvd: $14.50–$17.50 PSF (mid-bay, logistics-oriented)
• Hurontario / Derry Road: $13.50–$16.50 PSF (mixed vintage)
• Highway 401 / 410 Interchange: $14.00–$17.00 PSF (distribution-focused)
• Older Lakeshore / Lakeview corridors: $11.00–$14.00 PSF (legacy stock, lower clear heights)

These ranges reflect stabilized, arm's-length transactions. Off-market deals, lease renewals, and distressed situations can fall outside these bands in either direction.

2. TMI — Taxes, Maintenance, and Insurance

TMI is the landlord's pass-through of three specific cost categories:

• Property taxes: Assessed and billed by the City of Mississauga / Region of Peel. Industrial properties in Mississauga carry a tax rate that, depending on assessed value and property class, typically translates to $2.50–$4.50 PSF annually.
• Building insurance: Usually $0.15–$0.35 PSF. Tenants with high-value inventory or specialized operations may be required to carry additional coverage.
• Common area maintenance: Landscaping, parking lot upkeep, exterior lighting, snow removal, and shared building systems. This is where costs can creep — especially in multi-tenant buildings with aging infrastructure.

In aggregate, TMI in Mississauga runs $4.50–$7.00 PSF in 2026. Newer Class A product at the higher end; older 1980s–1990s stock can sometimes be lower on a tax basis but higher on maintenance due to deferred capital.

Investor note: When underwriting an acquisition, always request the last 3 years of actual TMI reconciliations, not just the landlord's estimate. Budget variances — particularly on property tax reassessments and snow removal — can significantly impact NOI.

3. CAM — Common Area Maintenance (Standalone)

In some leases, CAM is broken out separately from the broader TMI figure. This matters because CAM charges on controllable expenses (janitorial, landscaping, property management fees) are negotiable in ways that taxes and insurance are not.

For single-tenant buildings — which represent a significant share of Mississauga's larger-bay industrial stock — CAM is often minimal or embedded in a flat NNN structure where the tenant assumes full responsibility for the building. For multi-tenant industrial parks, CAM is allocated on a pro-rata basis by square footage and can range from $0.75 to $2.50 PSF depending on property complexity.

Escalation Clauses: The Long-Term Cost You Can't Ignore

Fixed annual rent bumps are now standard in Mississauga industrial leases. In 2026, the most common structures are:

• Fixed percentage increases: 3%–4% annually, compounding. On a 10-year lease starting at $15.00 PSF, a 3.5% annual bump brings the Year 10 net rent to approximately $21.20 PSF.
• CPI-linked increases: Less common but present in some institutional leases. Usually capped at 3%–5% to protect both parties.
• Step rent schedules: Fixed bumps at defined intervals (e.g., every 2 years). More common in older leases or deals with significant tenant improvement allowances.

For tenants, the practical advice is simple: model the full lease term, not just the current year's rent. A deal that looks competitive at $14.50 PSF in Year 1 with 4% annual bumps costs $20.90 PSF in Year 10. That's a material difference for occupancy cost planning.

For investors, escalating rents are a positive — they support NOI growth and protect against inflation. But only if the tenant can actually sustain those costs. Underwrite the tenant's business, not just the lease.

Tenant Improvement Allowances and Free Rent: What's Market in 2026

Mississauga landlords are more selective with concessions than they were during the frothy 2021–2022 period, but TI allowances and free rent remain part of deal-making — particularly for longer lease terms.

Current market ranges:

• Tenant Improvement (TI) Allowances: $15–$40 PSF for new leases on 5–10 year terms, depending on building vintage and landlord motivation. Existing vanilla warehouse space with minimal fit-out needs typically sees the lower end; office-heavy or cold storage conversions can push higher.
• Free Rent: 2–4 months on a 5-year deal; 4–8 months on a 10-year deal. Landlords are more willing to offer free rent than reduce face rent, as it preserves the comparable for future leasing.

For investors acquiring a building with a new lease in place, always calculate effective rent (net of free rent and amortized TI) rather than face rent. The difference matters for first-year NOI and DSCR calculations.

Structural Lease Terms That Affect Asset Value

Beyond rent and TMI, several lease provisions directly affect how an investor should value a Mississauga industrial asset:

• Renewal options: Standard 2–3 renewal periods of 5 years each, typically at market rent or with a defined floor. Renewal options reduce rollover risk but can cap upside if market rents rise sharply.
• Assignment and subletting: Most institutional leases restrict assignment without landlord consent. For investors, this matters if a tenant wants to sublease surplus space — a growing dynamic post-pandemic.
• Demolition and redevelopment clauses: Rare but present in older Mississauga properties near intensification zones. A landlord demolition clause can significantly reduce asset value from a tenant's perspective.
• ROFO/ROFR provisions: Right of first offer or refusal to purchase the building. Common in sale-leaseback structures and owner-user conversions. These provisions can complicate a future sale process.

Putting It Together: Total Occupancy Cost as the Real Benchmark

The most useful number for both tenants and investors is total occupancy cost per square foot — the all-in annual cost of being in the space. For a typical Mississauga mid-bay industrial deal in 2026:

That $22–$23 PSF figure is what a tenant's finance team should be stress-testing against their revenue per square foot and margin structure. It's also what an investor should be benchmarking against comparable deals when assessing whether a lease is above, at, or below market.

Final Thoughts

Mississauga's industrial lease market in 2026 rewards those who read the full document — not just the rent line. TMI variability, escalation compounding, CAM audit rights, and structural lease provisions all have real economic consequences. Whether you're a tenant negotiating your next deal or an investor underwriting an acquisition, the discipline of modeling total occupancy cost and stress-testing every assumption is what separates a good deal from an expensive mistake.
