Direct Answer (TL;DR for Ontario Small Business Tenants)
In Ontario, commercial tenants do NOT have the consumer protections of the Residential Tenancies Act. Commercial leases are governed by the Ontario Commercial Tenancies Act and the strict wording of the contract you sign. Even more importantly, an "Offer to Lease" (or Agreement to Lease) is a legally binding contract—and most landlord Offers to Lease contain a clause requiring you to sign the landlord's standard-form lease "substantially as presented" unless your lawyer adds specific protective conditions and rider clauses before you sign the Offer to Lease.
Astor Nobel Law provides a Fixed-Fee Commercial Lease or Offer to Lease Review ($1,250 flat + HST) with a 48-to-72 business hour turnaround, reviewed personally by Toronto business and litigation lawyer David Rose, Barrister & Solicitor (over 25 years of experience). You receive:
- A complete review of your Offer to Lease or Commercial Lease (up to 45 pages);
- A Plain-English Tenant Risk Memo identifying hidden financial exposures, operating traps, and default risks;
- Ready-to-Insert Schedule / Rider Clauses & Redlines (limiting personal obligations, capping controllable operating expenses, protecting renewal options, and adding notice/cure periods); and
- A 20-minute review call with David Rose to plan your negotiation with the landlord or commercial broker.
Summary Table: The 10 High-Risk Clauses in an Ontario Commercial Lease
| # | Clause / Trap | Typical Landlord Template Wording | What a Lawyer Negotiates for the Tenant |

| 2 | Personal Indemnity / Guarantee | Unlimited joint & several personal liability for the entire 5–10 year term + renewals | Rolling dollar cap (e.g., 12 months' rent) or sunset/burn-off after Year 2 or Year 3 of on-time payments |

Deep Dive: 10 Clauses Every Ontario Small Business Tenant Should Check Before Signing
1. Why Waiting Until After You Sign the "Offer to Lease" Is a Costly Mistake
Commercial brokers and landlords frequently present a 4-to-8 page Offer to Lease and tell the tenant: "This just locks in the base rent and possession date—your lawyer can review the formal lease later."
In Ontario law, a signed Offer to Lease is a binding contract. Almost every standard Offer to Lease states that the tenant agrees to sign the landlord's standard-form lease within 10 or 15 days, with no changes except those expressly written into the Offer to Lease. If you have already signed an unconditional Offer to Lease and handed over a deposit cheque for first and last months' gross rent, you have lost 90% of your leverage to negotiate personal liability limits, HVAC caps, demolition clauses, or restoration waivers in the formal lease.
- Practical Rule: Always have your lawyer review the Offer to Lease before you sign it—or insert a clear condition making the Offer conditional upon review and approval of both the Offer and the formal Lease by the Tenant's solicitor within 5 business days.
2. Unlimited Personal Indemnities (Even When You Incorporated Your Business)
Founders incorporate an Ontario company specifically to protect their home and personal savings from business debts. Landlords know a newly formed corporation has limited assets, so they almost always insert a Personal Guarantee or Indemnity Agreement (typically signed by the founder personally as "Indemnifier").
Notice that landlords prefer an Indemnity over a traditional Guarantee because an Indemnifier creates a primary obligation that survives even if the lease is modified, assigned, or disclaimed in insolvency. On a 5-year Toronto retail or office lease at $5,000/month gross rent, an unlimited personal indemnity is a $300,000 personal liability.
- How to Protect Yourself: If the landlord will not waive the personal indemnity in exchange for a slightly larger security deposit, negotiate:
- A burn-off / sunset date (for example, the personal indemnity automatically expires at the end of Year 2 or Year 3 provided the tenant has not been in monetary default); or
- A maximum dollar cap (for example, capped at the equivalent of 6 or 12 months of Minimum Rent) rather than the entire remaining 5- or 10-year term.
3. TMI / Additional Rent, Capital Repairs, and Management Fee Markups
In a "Net" or "Triple Net" commercial lease, your monthly Minimum (Base) Rent is only part of your occupancy cost. You also pay Additional Rent (often called TMI — Taxes, Maintenance, and Insurance, or CAM — Common Area Maintenance).
Landlord leases frequently define Operating Costs so broadly that the landlord can bill tenants for:
- Structural repairs to the roof deck, foundation, or load-bearing walls;
- Replacing the entire parking lot or boiler in a single year;
- Environmental remediation of pre-existing contamination; and
- A 15% administration/management fee charged not only on maintenance, but also on property taxes, insurance premiums, and utility bills.
- How to Protect Yourself: Require an itemized exclusion of structural repairs and pre-existing environmental issues, require capital replacements to be amortized over their useful life under GAAP, exclude property taxes and utilities from the 15% administration fee base, and negotiate an annual percentage cap (e.g., 5% per year) on controllable operating cost increases.
4. The Aging HVAC Unit Trap
One of the most common $15,000–$30,000 shocks for Ontario retail, restaurant, medical, and industrial tenants is the HVAC clause. Standard landlord leases make the tenant 100% responsible for maintaining, repairing, and replacing the heating, ventilation, and air conditioning units serving the premises—even if the unit on the roof is already 18 years old on the day you move in and fails six months into a 5-year lease.
- How to Protect Yourself: Require a landlord representation and warranty that all base-building mechanical, electrical, plumbing, and HVAC systems are in good working order on possession, make the landlord responsible for major capital replacement during the term (or cap your annual HVAC repair/replacement exposure), or amortize any capital HVAC replacement over a 12-to-15-year useful life so you only pay your remaining term's fraction.
5. Demolition and Redevelopment Clauses
Across Toronto and the GTA, many plaza and street-front commercial buildings are potential condo or mixed-use redevelopment sites. A standard Demolition Clause allows the landlord to terminate your lease early on 6 months' notice if the landlord decides to demolish, renovate, or redevelop the property—leaving you with zero compensation after you just spent $80,000 to $250,000 on your interior build-out, signage, and local customer goodwill.
- How to Protect Yourself: Confirm upfront whether a redevelopment application has been filed. If a demolition clause cannot be deleted, negotiate a no-demolition lock-out period (e.g., cannot take effect during the initial 5-year term), at least 12 months' prior written notice, rent-free occupancy during the final notice months to fund your move, and landlord reimbursement of your unamortized leasehold improvement costs.
6. Relocation Clauses inside Plazas and Office Buildings
A Relocation Clause allows the landlord to force your business to move from your sunny corner unit near the main entrance to a back-corridor unit whenever a larger tenant wants your space.
- How to Protect Yourself: Strike the relocation clause for street-front or destination retail/clinic spaces. If the landlord insists on keeping it in an office or shopping centre lease, require that any substitute space be at least equal in size, frontage, visibility, and foot traffic, with the landlord paying 100% of your build-out, signage, cabling, moving, and re-printing costs upfront.
7. Permitted Use and Competitor Exclusivity
If your Permitted Use clause is drafted too narrowly (for example, "for the retail sale of specialty espresso beverages and for no other purpose"), the landlord can block you from adding baked goods, sandwiches, branded merchandise, or subleasing the space later. Conversely, without an Exclusivity Clause, the landlord can rent the unit right next door to a competing coffee shop six months after you open.
8. Selling Your Business Later: Assignment, Subletting & Landlord "Recapture" Rights
If you build a successful retail store, clinic, restaurant, or service business and want to sell it in four years, the buyer will need to take over your lease (either by Assignment of Lease or by buying the shares of your corporation, which triggers the lease's Change of Control clause).
Many landlord leases contain a "Right of Recapture"—meaning that when you ask for the landlord's consent to assign the lease to a buyer of your business, the landlord can instead cancel your lease and take back the premises for themselves!
- How to Protect Yourself: Ensure that the landlord's recapture right does not apply to a bona fide sale of your operating business, and that landlord consent to an assignment or change of control cannot be unreasonably withheld or delayed.
9. Default, Written Notice & Cure Periods, and Landlord Distress Under the Ontario Commercial Tenancies Act
In Ontario, under the Commercial Tenancies Act, if rent is in arrears, a landlord has broad common-law and statutory remedies: they can either distrein (keep the lease alive and seize your inventory/equipment inside the unit to sell for unpaid rent) or forfeit/re-enter (change the locks and terminate the lease—though a landlord cannot legally do both at the same time).
- How to Protect Yourself: Never accept an instant-default clause where a banking glitch or a 3-day delay allows immediate lockout. Negotiate a mandatory written notice and cure period (at least 5 to 10 business days after written notice for monetary defaults, and 20 to 30 days after written notice for non-monetary defaults).
10. End-of-Lease Restoration ("Make Good" Obligations) and Holdover Rent
Many commercial leases contain a hidden clause near the back requiring the tenant, at the end of the lease, to remove all leasehold improvements, partition walls, flooring, and plumbing and restore the unit to a bare concrete base-building shell—even for improvements the landlord approved at the start of the lease! That demolition bill alone can cost $20,000 to $60,000 when you move out.
- How to Protect Yourself: Add a clear clause stating that the tenant is not required to remove initial Landlord-approved leasehold improvements at the end of the term, and may leave the premises in broom-swept condition, reasonable wear and tear excepted.
