The Option to Renew: Ontario Law Won’t Protect Your Commercial Lease — Only This Clause Will
Residential tenants have legal backstops at expiry. Commercial tenants don’t. Whether the shop you spent six figures fitting out can be renewed, and at what rent, is something Ontario’s Commercial Tenancies Act says nothing about — it all comes down to how the renewal clause was written.
Do commercial tenants have an automatic right to renew at expiry?
No. Under Ontario’s Commercial Tenancies Act, a commercial tenant has no statutory right to renew — once the term expires, your right to occupy is determined entirely by the terms of the lease itself. This is the opposite of residential leasing (where tenants get layers of legal protection). So for a commercial tenant, an option to renew must be negotiated as an explicit clause at signing, or the landlord is free to take the space back or raise the rent at will.

I’m Arthur Zhao. Here’s a costly assumption commercial tenants make: “I’ve been here for years and paid for the buildout myself — surely renewal is a given.” But Ontario commercial leasing is a different world from residential — it gives commercial tenants no automatic renewal backstop at all. The restaurant, clinic, or shop you spent $200-300K fitting out can be refused renewal or hit with any rent increase the landlord wants — and the only thing protecting you is the renewal clause in the lease you signed. How that one clause is written decides whether your business has roots.

Why the option to renew is a tenant’s lifeline
How renewal rent is set — FMR is the most dangerous
Don’t let your own fit-out inflate your renewal rent
⚠️An FMR renewal clause is double-edged: it lets the landlord reset rent to market, and in a hot market you may face renewal costs well above plan. Always pair it with three things: a defined valuation mechanism (e.g. each side appoints an appraiser), an increase cap, and exclusion of tenant-funded improvements. A bare FMR clause hands rent-setting power to the landlord.
The notice period: miss it and it’s void
💡 Remember three things: ① Ontario law gives commercial tenants no automatic renewal right — only the lease clause does; ② how renewal rent is set (FMR vs fixed escalation vs cap) affects your money more than whether you have an option at all; ③ exercising the option has a hard written-notice deadline, void if missed. Get any one wrong and the option is a paper promise.
Can the option travel with the business when you sell?
ℹ️The option, FMR pricing, notice period, and assignability are all negotiable and interrelated clauses. A commercial lease often runs five or ten years and binds hundreds of thousands of your investment — have a lawyer experienced in commercial leasing vet every clause before signing. The legal fee is trivial against the operating base you could lose.
Frequently Asked Questions
I’ve rented for years and paid for the fit-out — surely the landlord has to let me renew?
Not necessarily. Ontario’s Commercial Tenancies Act gives commercial tenants no automatic renewal right; whether and at what rent you can renew depends entirely on whether — and how — a renewal clause was written into your lease. Long tenure and heavy investment create no legal right to renew. The only protection is the clause, which is exactly why you must negotiate it at signing.
Is a fair market rent (FMR) renewal good or bad for me?
Usually unfavourable to tenants and the landlord’s preferred approach. It sets rent at market at renewal, so in a hot market your cost can jump, and “market” itself is often disputed. If you must accept FMR, pair it with a defined valuation method, an increase cap, and a clause excluding your own funded improvements — to contain the uncertainty.
What if I miss the notice period to exercise the option?
It’s generally treated as a waiver of the option, and the landlord can take the space back — the deadline is hard. Too many tenants miss the written-notice date while busy operating and forfeit the option for nothing. There’s little recourse, so put the deadline in your calendar with multiple reminders on signing day and never rely on memory.
If I sell my business later, does the renewal option transfer?
Only if the lease expressly provides for it. A buyer of your business cares most about how long the location can be held, and a non-assignable option that ends at expiry lowers your resale value. Negotiate at the outset for the option to be assignable with the business/lease, or that the landlord will consent to the assignment — it directly determines your exit price.
