Residential and commercial real estate law in Ontario protect very different things. Residential law is built to shield homebuyers and tenants, while commercial law assumes you are a business making your own decisions, so it gives you far fewer automatic protections and expects you to investigate before you sign.
That single difference drives almost everything else, from which statute governs your lease, to whether you pay HST on the purchase price, to who hears a dispute and how quickly. This guide walks through the practical differences that matter when you buy, sell, lease, or invest in Ontario property, with the rules current as of June 2026.
What is the difference between commercial and residential real estate law in Ontario?
Residential real estate covers property meant for living. That includes detached and semi detached houses, condominiums, and rental apartment units. The law in this area governs purchase agreements, mortgages, closings, and the relationship between residential landlords and tenants.
Commercial real estate covers property used to run a business or earn income. That includes offices, retail units, restaurants, warehouses, industrial space, and multi unit investment buildings. The law here governs the purchase and sale of those assets, leasing between businesses, development, financing, and tax.
The dividing line is use, not size. A small storefront is commercial. A large house you live in is residential. Buildings that mix the two, such as a shop with apartments above it, get split between the two sets of rules, which we explain below.
Here is how the two compare on the points that usually decide a deal.
| Feature | Residential | Commercial |
|---|---|---|
| Governing lease law | Residential Tenancies Act, 2006 | Commercial Tenancies Act |
| Buyer and tenant protection | Strong, set by statute | Limited, you negotiate your own |
| Purchase contract | Standard OREA form, many terms fixed by law | Custom agreement, heavily negotiated |
| HST on the purchase price | Resale homes generally exempt | Generally taxable at 13% |
| First time buyer land transfer tax rebate | Available if you qualify | Not available |
| Typical down payment | As low as 5% on insured purchases | Often 25% or more |
| Rent control | Yes for most units occupied before Nov 15, 2018 | None |
| Dispute forum | Landlord and Tenant Board | Small Claims Court or Superior Court of Justice |
| Due diligence expected | Limited, seller discloses known defects | Extensive, buyer must investigate |
Which side gets legal protection, and which is left on its own?
Residential law leans toward the person with less bargaining power, the buyer or the tenant. The Residential Tenancies Act, 2006 sets the rules for rent increases, notice, and ending a tenancy, and a public tribunal called the Landlord and Tenant Board hears most disputes. Sellers of homes also have to disclose certain hidden defects they know about.
Commercial law assumes two businesses dealing at arm’s length. There is very little statutory protection. The principle is closer to buyer beware. If you do not investigate the zoning, the environmental history, the existing leases, or the condition of the building, that risk is usually yours to carry. This is why commercial buyers run a due diligence period before the deal becomes firm.
On the residential side, the law fills gaps in your favour. On the commercial side, your contract is the protection, so what you negotiate is what you get.
How the purchase agreements differ
Residential deals usually run on the standard Ontario Real Estate Association agreement of purchase and sale, the same form most buyers and sellers see. Many terms are familiar and several protections are built in by law.
Commercial deals use a custom agreement drafted for the specific property. It deals with things a home purchase rarely touches, such as the assignment of existing tenant leases, environmental representations, deposits held from tenants, the permitted use of the space, and exactly how HST will be handled. The conditional period is longer and broader. It often covers financing, a building inspection, an environmental review, and a careful read of every lease and service contract attached to the property.
In a home purchase you are mostly working through a known form. In a commercial purchase you are negotiating the document itself, and the wording decides your risk.
HST, the cost most people miss on commercial deals
This is the difference that catches buyers off guard. The sale of a resale home in Ontario is generally exempt from HST. The sale of commercial property is generally taxable at 13%. On a one million dollar commercial purchase, that is 130,000 dollars you have to plan for.
Commercial rent is taxable too. A commercial landlord charges HST on the rent, including the operating cost and property tax portions that the tenant pays. Residential rent is not taxed.
New homes bought from a builder are also taxed, unlike resale homes, although a new housing rebate may reduce the cost. We cover that in our guide to buying a condo.
Because the result turns on the specific facts, ask early whether HST applies and make sure the agreement states clearly whether the price includes it or not. Confirm the current treatment with your lawyer and your accountant before you sign. The answer depends on the facts of your deal, and getting it wrong is expensive.
Land transfer tax and the cash you need to close
Every buyer in Ontario pays provincial land transfer tax when the property changes hands. If the property sits inside the City of Toronto, you pay a second municipal land transfer tax on top of it. Toronto is the only municipality in Ontario that charges its own.
First time home buyers can claim a rebate of up to 4,000 dollars on the provincial tax and, in Toronto, up to 4,475 dollars on the municipal tax, for as much as 8,475 dollars combined. These rebates apply to a home you will live in. They do not apply to commercial or investment property.
Two things have changed and are worth flagging. As of April 1, 2026, Toronto applies higher graduated municipal rates to high value residential properties, so confirm the current rate before you close. And the federal First Time Home Buyer Incentive, the shared equity program run through the Canada Mortgage and Housing Corporation, was discontinued in 2024 and no longer accepts applications. If an older article points you to it, ignore that.
Commercial buyers pay land transfer tax as well, with no first time rebate, on top of the HST described above and larger legal and due diligence costs.
These figures are current as of June 2026. Confirm them against the Ontario Ministry of Finance and the City of Toronto before you rely on them, since rates and rebates move. The practical step is to budget land transfer tax separately from your down payment, because it is due on closing day and you cannot fold it into the mortgage.
Financing, and why commercial deals need more cash
Residential mortgages are standardized and sit inside a system built around individual homeowners. An insured purchase can go ahead with as little as 5% down, and some insured mortgages now allow amortizations of up to 30 years.
Commercial lending is its own world. Lenders look at the income the property produces, not just your salary. They usually want a larger down payment, often 25% or more, a shorter amortization, and they may use tools such as bridge financing to cover the gap between deals. Approval takes longer and the paperwork is heavier.
These figures reflect common market practice rather than a fixed legal rule, and lenders vary. Line up commercial financing early and build the larger cash requirement into your plan from the start.
Leases, two completely different rulebooks
Residential and commercial leases are governed by different statutes, and tenants get hurt by assuming the protections are the same. They are not.
Residential tenancies fall under the Residential Tenancies Act, 2006. It caps the annual rent increase for most units first occupied on or before November 15, 2018, and the provincial guideline for 2026 is 2.1%. A residential landlord has to use the standard lease, give 90 days notice on the prescribed form before raising the rent, and go through the Landlord and Tenant Board to evict. You can read the current guideline on the Ontario government rent increase page.
Commercial tenancies fall under the Commercial Tenancies Act. There is no rent control, no mandatory standard lease, and no Landlord and Tenant Board. If a commercial landlord and tenant end up in a dispute, a claim up to 50,000 dollars goes to Small Claims Court and anything larger goes to the Superior Court of Justice. The province explains this on its renting commercial property page.
The remedies are tougher as well. If a commercial tenant falls behind on rent, the landlord can use a self help remedy called distress, seizing and selling the tenant’s goods on the premises without a court order, within limits. Or the landlord can change the locks and end the tenancy as early as the sixteenth day after the rent was due. The landlord has to choose one path or the other for the same default, not both.
A business owner who signs a store lease expecting the kind of protection a home tenant gets is in for a shock, because none of it applies. Your lease is your protection. Have it reviewed before you commit, since the term can lock you in for years. Our commercial lease lawyers can do that, and our commercial lease guide for Ontario walks through the clauses that matter most.
Zoning, land use, and construction rules
Residential zoning focuses on safe, livable neighbourhoods. If you renovate a home or add to it, you follow the municipal zoning bylaw and the building code and you pull permits, but the path is usually straightforward.
Commercial zoning is stricter and more layered. It controls what business can operate where, along with parking, signage, and environmental impact. Before you commit to a commercial property, confirm the zoning allows your intended use. You may need a rezoning or a minor variance, and that takes time. Our explainer on Toronto zoning bylaws goes deeper on this.
Construction rules are heavier on the commercial side too, with more rigorous code requirements for larger and public buildings and more demanding permit and approval processes. We cover the detail in our piece on commercial building codes in Ontario. The practical rule is simple. Never assume a property can be used the way you plan. Check the zoning before the deal goes firm, not after.
Property taxes
Both residential and commercial properties are taxed on their assessed value through the Municipal Property Assessment Corporation. The difference is the rate. Municipalities tax commercial property in a separate class at a higher rate than residential, so two buildings worth the same amount can carry very different annual tax bills.
For a business, property tax is an operating cost you plan for every year. For a homeowner it is a household cost. Either way, get the actual annual property tax figure and any local business charges in writing during due diligence, not after you own the place.
Frequently asked questions
Is a duplex or triplex residential or commercial?
It depends on how it is used and financed. A small owner occupied building with a couple of rental units is usually treated as residential for the tenancy rules, so the Residential Tenancies Act applies to those tenants. Once a building is larger or held purely as an investment, financing, tax, and the lease rules can shift toward the commercial side. This is one of those areas where the honest answer is that it turns on the specifics, so it is worth a quick check before you buy.
Do I pay HST when I buy a commercial property in Ontario?
Generally yes, at 13% of the price. If you are registered for HST you can often report it directly to the Canada Revenue Agency rather than paying the seller on closing, and you may be able to recover it through an input tax credit if you use the property in a business. The treatment depends on the facts, so confirm it with your lawyer and accountant and make sure the agreement says whether HST is included or in addition to the price.
Does the Residential Tenancies Act protect my business lease?
No. A commercial lease is governed by the Commercial Tenancies Act, which gives far fewer protections. There is no rent control, no mandatory standard lease, and no Landlord and Tenant Board. The terms you negotiate into the lease are what protect you, which is why a review before signing matters so much.
Can a commercial landlord lock me out for missing rent?
Yes. Under the Commercial Tenancies Act a landlord can change the locks and end the tenancy as early as the sixteenth day after the rent was due, or instead seize and sell your goods on the premises, but not both for the same default. If you are locked out you may be able to apply to the Superior Court for relief from forfeiture, usually by paying the arrears and costs, so act quickly and get advice.
Do the first time buyer rebates apply to investment property?
No. The provincial and Toronto land transfer tax rebates apply only to a home you will live in as your principal residence. They are not available for commercial property or for a property you buy purely as an investment.
How much more does a commercial deal cost than a residential one?
More, on several fronts. Expect HST on the purchase, a larger down payment, and higher legal and due diligence costs because there is more to review. The exact difference depends on the property and the deal. Our fee section above sets out what we charge once you confirm the figures with us.
