When you compare commercial vs residential property in Ontario, the dividing line is statutory protection versus freedom of contract. Residential property sits inside a protective regime: the Residential Tenancies Act caps rent increases, consumer mortgage rules govern financing, and resale homes are exempt from HST. Commercial property runs on freedom of contract under the Commercial Tenancies Act, with no rent control, taxable HST, far larger down payments, and a landlord's self-help remedy that no longer exists on the residential side. Same words, different law.
If you have only ever dealt with residential property, the instinct is to assume commercial works the same way with bigger numbers. It does not. The legal frameworks were built on opposite assumptions. Residential law assumes an individual occupant who needs protection from a more powerful landlord or lender. Commercial law assumes two businesses negotiating at arm's length, each capable of looking out for itself. That single difference in starting point ripples through leasing, zoning, financing, tax, and remedies.
This is the most important thing to understand before you cross from residential into commercial as an owner or a tenant: the protections you took for granted were never something you negotiated. They were handed to you by statute. On the commercial side, most of them simply are not there, and the few that remain have to be written into your contract. Below are the five areas where the difference actually changes outcomes, and what each one means for you.
Leasing: Commercial vs Residential Lease Rules in Ontario
The clearest divide is in leasing, because two different statutes govern the two different worlds.
Residential leases fall under the Residential Tenancies Act, 2006 (the RTA). The RTA is deliberately protective. It limits how much a landlord can raise the rent each year through the annual rent increase guideline, it requires most landlords to use the province's standard lease form, it gives tenants security of tenure so they cannot be evicted without cause and a formal process, and it sends almost every dispute to the Landlord and Tenant Board rather than to court. A residential tenant who does nothing still benefits from all of this automatically.
Commercial leases fall under the Commercial Tenancies Act (the CTA), and the philosophy is the reverse. There is no rent control. There is no standardized lease. There is no automatic right to renew when the term ends. A commercial landlord can let the lease lapse and require the tenant to leave or negotiate a fresh deal at whatever rent the market will bear. Your rights as a commercial tenant come almost entirely from the words of the lease you signed, not from the statute. The CTA supplies a handful of baseline rules and remedies, but it does not act as a safety net the way the RTA does.
That shifts the burden of protection onto the negotiation. A renewal right, a cap on operating-cost pass-throughs, a relocation clause, an exclusivity covenant, an assignment right: if you want these in a commercial lease, you negotiate for them and put them in writing. Nothing is implied in your favour. Disputes also go somewhere different. Commercial landlord and tenant disputes are resolved in the courts, the Small Claims Court for money or property claims up to its monetary limit and the Superior Court of Justice for larger matters, rather than at the tenant-friendly Landlord and Tenant Board.
For a small business owner moving out of a home office into leased commercial space, this is the first and largest surprise. The lease is the law of the relationship, and it is usually drafted by the landlord's lawyer to favour the landlord.
Zoning and Permitted Use
The second difference is what you are allowed to do with the property in the first place.
In Ontario, what a property can be used for is controlled by municipal zoning by-laws made under the Planning Act. Residential use is comparatively standardized: a house in a residential zone is zoned to be lived in, and most buyers never think about it. Commercial property zoning in Ontario is parcel-specific and far less forgiving. A property zoned for retail may not permit a restaurant with a commercial kitchen. A unit zoned for office use may not allow light manufacturing or a medical clinic. The zoning attaches to the land, not to your business plan.
This matters enormously when you buy or lease commercial space, because buying or leasing a property that does not permit your intended use can stop you cold. It can prevent you from obtaining a business licence, and it can affect your ability to finance the purchase, because a lender will not want security over a property the borrower cannot legally operate. Before you commit, you confirm that the zoning by-law actually permits what you intend to do there.
If it does not, your options become legal and procedural rather than commercial: applying for a minor variance, seeking a zoning by-law amendment, or relying on legal non-conforming use rights if the use predates the current by-law. Site plan control and other municipal approvals may also apply. None of these are quick, and none are guaranteed. On the residential side, this layer of risk barely registers. On the commercial side, zoning due diligence is one of the first things a buyer's lawyer checks.
Financing and Due Diligence When Buying Commercial Property in Ontario
The third difference is how the deal gets financed and how much investigation you are expected to do yourself.
Residential financing is standardized and consumer-protected. A buyer can often purchase a home with a down payment in the range of 5 to 20 percent, mortgage disclosure rules protect borrowers, and the transaction is wrapped in consumer-protection law built around the assumption that the buyer is an individual, not a business.
Commercial financing assumes the opposite. When you are buying commercial property in Ontario, down payments are typically much higher, commonly in the range of 30 to 35 percent, and lenders scrutinize the income the property produces, the strength of the tenants, and the borrower's business rather than just personal credit. Specialized structures such as bridge loans and mezzanine financing appear on the commercial side that have no residential equivalent. There is no cooling-off period.
The due diligence burden also shifts. Residential buyers benefit from consumer-protection rules and relatively standardized disclosure. Commercial buyers operate closer to caveat emptor, buyer beware, and are expected to investigate the property thoroughly before closing. That diligence routinely includes an environmental site assessment (a Phase I, and a Phase II if the first raises concerns), a title search, a review of every existing lease and estoppel certificates from tenants, a survey, and confirmation of zoning and compliance. The seller is not obligated to volunteer most of this. If you do not look, you own the problem after closing.
For an owner moving from residential into commercial, this is where unexpected costs appear. The legal and consultant work that a commercial purchase requires is real, and it is the price of the protection you no longer get automatically.
HST on Commercial Property in Ontario
The fourth difference is tax, and it catches people off guard at closing.
Used residential real property is generally exempt from GST/HST. When an ordinary homeowner sells their house, no HST applies to the sale price. That exemption, found in the residential provisions of the Excise Tax Act, is one reason residential closings feel simple. (New construction and builder sales are a separate story with their own rules, which is why tax advice matters whenever a property is newly built or substantially renovated.)
The sale of commercial real property is generally taxable. In Ontario that means 13 percent HST on commercial property in most transactions, a significant number on a commercial purchase. The mechanics, however, are usually manageable. Where the purchaser is registered for GST/HST, the purchaser, not the vendor, accounts for the tax by self-assessing and reporting it to the Canada Revenue Agency, and in most cases claims an offsetting input tax credit so the net cash cost is neutralized. The Canada Revenue Agency's guidance on real property and the GST/HST sets out how this works.
The practical takeaways are two. First, HST is a live issue on every commercial purchase and must be addressed in the agreement of purchase and sale, including a representation about the purchaser's registration status. Second, getting the registration and self-assessment mechanics right is what keeps that 13 percent from becoming a real out-of-pocket cost. A buyer who assumes commercial works like residential, where HST simply does not arise, can be unpleasantly surprised.
Distraint and Landlord Remedies
The fifth difference is what a landlord can do when rent goes unpaid, and here the gap is dramatic.
In the residential world, the old common-law remedy of distress, seizing a tenant's goods to satisfy rent arrears, has been abolished. Under the Residential Tenancies Act, no landlord may seize a tenant's property for unpaid rent without legal process, so distress is simply not available. A residential landlord's path runs through the Landlord and Tenant Board.
In the commercial world, distress (also called distraint) is alive and powerful. Under the Commercial Tenancies Act, a commercial landlord facing a tenant's monetary default can exercise a self-help remedy: seize and, if the default is not cured, sell the tenant's goods on the premises, including chattels, equipment, and inventory, to satisfy the rent arrears, without first going to court. For a tenant, few things concentrate the mind like the prospect of a landlord lawfully padlocking the premises and seizing the business's inventory.
The remedy is not unlimited. A landlord can generally only distrain for a capped amount of arrears, typically the previous three months of rent, and can only seize property that is actually on the leased premises at the time. Certain goods are exempt. Importantly, distress and termination are treated as inconsistent remedies: a landlord who distrains for rent is generally affirming the lease continues and cannot at the same time terminate it for the same default, so the landlord must choose. The technical rules are exactly the kind of thing a tenant wants understood before signing and a landlord wants advice on before acting.
The lesson for someone crossing over is simple. The remedy that residential law deliberately stripped away from landlords is one of the strongest tools a commercial landlord holds. If you are the commercial tenant, you need to know it exists. If you are the commercial landlord, you need to exercise it correctly or you risk losing the remedy and facing a claim.
What Changes When You Cross From Residential Into Commercial Property
Step back and the pattern is consistent. Every protection that residential law hands you automatically, you either negotiate for on the commercial side or you live without it.
Rent stability becomes whatever your lease says. Security of tenure becomes your renewal clause or nothing. Permitted use becomes a zoning question you have to verify yourself. Simple financing becomes a larger down payment and a longer diligence list. A tax-free closing becomes a 13 percent HST line that has to be handled correctly. A landlord with limited remedies becomes a landlord who can seize your goods. None of this makes commercial property worse. It makes it different, and it shifts responsibility onto you and your advisors.
A short practical checklist for the crossover:
- Read the entire lease or agreement of purchase and sale. On the commercial side, the document is the deal.
- Verify zoning and permitted use against the actual municipal by-law before you commit.
- Budget for HST and confirm the registration and self-assessment mechanics in the agreement.
- Plan and pay for real due diligence: environmental, title, survey, existing leases, compliance.
- Understand the remedies on both sides, including distress, before a dispute arises.

Frequently Asked Questions
Is a commercial lease covered by the Residential Tenancies Act?
No. The Residential Tenancies Act applies only to residential tenancies. Commercial leases are governed by the Commercial Tenancies Act and, far more importantly, by the terms of the lease itself. The protective rules of the RTA, including rent control and Landlord and Tenant Board access, do not apply to commercial space in Ontario.
Do commercial tenants in Ontario have any protection?
Some, but most of it comes from the lease rather than from statute. The Commercial Tenancies Act provides baseline rules and a limited right to seek relief from forfeiture, but there is no rent control, no standard lease, and no automatic renewal. A commercial tenant's real protection is whatever was negotiated into the written lease before signing.
Is HST charged on the sale of commercial property in Ontario?
Generally yes. Most sales of commercial real property in Ontario are taxable at 13 percent HST, while used residential property is generally exempt. Where the buyer is registered for GST/HST, the buyer self-assesses and reports the tax to the Canada Revenue Agency and usually claims an offsetting input tax credit, which neutralizes the cash cost.
Can a commercial landlord seize a tenant's property for unpaid rent?
Yes. Under the Commercial Tenancies Act, a commercial landlord can exercise the remedy of distress and seize, and ultimately sell, a tenant's goods on the premises to cover rent arrears without a court order, subject to caps and exemptions. This remedy has been abolished for residential landlords under the Residential Tenancies Act.
How much down payment do you need for commercial property in Ontario?
There is no fixed legal minimum, but commercial lenders commonly require a down payment in the range of 30 to 35 percent, considerably more than a residential purchase, which can be financed with as little as 5 to 20 percent down. Commercial lenders also weigh the property's income and tenants, not just the borrower's personal credit.

If you are an owner or tenant moving from residential into commercial property in Ontario, the safest assumption is that none of your residential instincts carry over. The lease is the law of the relationship, zoning controls what you can do, HST is live on the purchase, and the landlord's remedies are far stronger. Getting advice before you sign a commercial lease, or before you close on a commercial purchase, is what keeps a routine-looking deal from turning into an expensive one.
