Buying a Property for Your Business in Ontario: What You Need to Know

For many Ontario small business owners, buying a property to operate from is a defining milestone — the point at which the business stops paying someone else's mortgage and starts building equity of its own. Whether you run a dental practice, a trades company, a retail shop, or a professional services firm, buying property for your business in Ontario comes with significant upside. It also comes with a set of legal, tax, and financing decisions that are quite different from buying a home or an investment property.

This guide walks through the key decisions: whether to buy or lease, how to hold the property, HST, zoning, commercial financing, and the due diligence steps your lawyer will work through with you. Every situation is different — the goal here is to give you a clear map before you start the process.

Buying vs leasing: the key trade-offs

Leasing is simple. You pay rent, the landlord handles the building, and your capital stays in the business. For early-stage businesses, businesses with uncertain space needs, or owners who want to stay mobile, leasing often makes the most sense.

Buying changes the equation in several important ways. Your monthly mortgage payment builds equity rather than disappearing as rent. You control the space — no risk of a landlord declining to renew, redeveloping the property, or raising rent sharply at renewal. Over time, commercial real estate can appreciate, adding to your net worth. And if your business ever occupies less than the full building, you may be able to lease out unused space to generate income.

The trade-offs are real, though. Commercial mortgages typically require larger down payments than residential ones. The purchase locks up capital that might otherwise fund growth. You take on responsibility for maintenance, property taxes, and capital repairs. And if your business needs to move or scale quickly, owning property can be a constraint rather than an asset.

Buying tends to make more sense when your business has stable space requirements, when you plan to stay in the same location for several years, and when the local real estate market supports the investment thesis. Leasing tends to be smarter when flexibility matters more than stability, or when the capital required for a purchase would be better deployed elsewhere in the business.

Should you buy in your personal name or through a corporation?

This is one of the most consequential decisions you will make, and the right answer depends on your tax situation, your business structure, and your long-term plans. What follows is a general overview — you should work through the specifics with your accountant and a tax lawyer before you proceed.

Personal ownership is simpler to set up. When you eventually sell, you may be able to claim the principal residence exemption if the property partially qualifies, though commercial property rarely meets that test in full. Capital gains on the sale are taxed at your personal marginal rate on fifty percent of the gain (as of writing — verify current inclusion rates).

Corporate ownership keeps the property inside your business structure, which can offer liability protection: if someone is injured on the premises, your personal assets are generally shielded by the corporate veil, provided the corporation is properly maintained. If your operating company owns the property and later faces financial trouble, the property is exposed to creditors. For that reason, many business owners hold commercial real estate in a separate holding corporation rather than the operating company — the operating company pays rent to the holdco, and the holdco owns the bricks and mortar.

When your corporation owns the property and you charge your operating company rent, that rent is generally income in the corporation's hands. Depending on your structure and provincial rules, passive income inside a corporation may be taxed at a higher rate than active business income, and it can reduce the small business deduction available to your operating company. These rules are detailed and change periodically. Speak with an accountant and a tax lawyer about which structure makes sense before you sign an Agreement of Purchase and Sale.

Zoning: can you actually run your business there?

Before you fall in love with a property, confirm that your intended use is permitted under the local zoning by-law. Zoning in Ontario is governed by municipal by-laws under the Planning Act. Each municipality divides its land into zones — commercial, industrial, mixed-use, residential, and various subcategories — and each zone has a list of permitted uses.

A property may look perfect but be zoned for a use that does not include your business type. A retail shop, a medical clinic, a light manufacturing operation, and a professional office may each require a different zoning designation. Your real estate lawyer will search the applicable by-law and can help you identify whether the use is permitted as of right, whether a minor variance or rezoning would be required, or whether the property simply does not work for your purposes.

If you are buying a property that was previously used for a different business type, do not assume your use is grandfathered in. Non-conforming use protections in Ontario are narrow and fact-specific.

Home-based businesses face a separate set of rules. Many Ontario municipalities permit limited home-based businesses under residential zoning, but with significant restrictions — on signage, on the number of employees, on customer visits, and on the proportion of the home used for business. If you plan to buy a residential property and run a business from it, review the municipal by-law carefully before you commit.

HST on owner-occupied commercial purchases

In most cases, the purchase of commercial real estate in Ontario attracts HST. This is a major difference from residential real estate, where HST generally does not apply to resale homes.

If you are an HST registrant — which most businesses with annual revenues above the registration threshold are required to be (as of writing — verify current threshold) — you can generally claim an Input Tax Credit (ITC) to recover the HST you paid on the purchase, provided the property is being used in your commercial activities. The mechanics of how and when the ITC is claimed, and whether the vendor or purchaser is responsible for remitting HST, depend on the structure of the transaction. Your lawyer and accountant will work through this with you before closing.

If you are not an HST registrant, or if part of the property will be used for exempt activities, the HST position is more complex. Do not assume HST is simply included in the price or waived — get advice specific to your transaction.

Financing an owner-occupied commercial property

Commercial mortgages are structured differently from residential ones. Lenders typically require a larger down payment — commonly in the range of twenty-five to thirty-five percent of the purchase price, though this varies by lender, property type, and your business profile (as of writing — verify current lender requirements).

The Canada Mortgage and Housing Corporation (CMHC) offers programs aimed at small business owners acquiring owner-occupied commercial property. Program details, eligibility criteria, and availability change over time — verify current offerings with your lender or broker before you rely on them in your planning.

Lenders assessing an owner-occupied commercial purchase will look at your business financials, not just personal credit. They want to see that the business generates sufficient cash flow to service the debt. If the property has other tenants whose rent will contribute to debt service, lenders will scrutinize the leases carefully. Be prepared to provide two to three years of business financial statements, your personal net worth statement, and details on the property.

Legal due diligence for owner-occupied buyers

Your lawyer's due diligence work on a commercial purchase is more extensive than on a residential transaction. Key items include:

Title search: confirms the vendor has clear title to convey and reveals any encumbrances, liens, easements, or restrictions registered against the property.

Zoning compliance: confirms the current use is legally permitted and flags any outstanding variances or conditions attached to prior approvals.

Survey: a current survey identifies the boundaries, any encroachments, and easements that may affect your use of the property.

Environmental: for commercial and industrial properties, a Phase I Environmental Site Assessment is standard practice and often required by your lender. It reviews historical land use to assess the risk of contamination. If the Phase I raises concerns, a Phase II (physical testing) may follow. Environmental issues can be expensive to remediate and can affect financing, insurance, and future sale.

Existing leases: if the property has tenants, their leases survive the sale. Review all leases carefully — terms, renewal options, exclusivity clauses, and any tenant rights to purchase.

Work orders and compliance: search for outstanding work orders, building permits, and zoning violations. Unresolved compliance issues become your problem after closing.

Closing and taking possession

Commercial closings involve several moving parts beyond the residential norm.

Adjustments at closing typically include property taxes, utilities, prepaid rents from existing tenants, and any other amounts that straddle the closing date. Your lawyer prepares a statement of adjustments so both parties know exactly what is owed on closing day.

HST on closing: as noted above, HST may be payable at closing, and the mechanics of how it is handled — whether the vendor collects it or the purchaser self-assesses and remits directly — should be settled well before the closing date.

Transfer of utilities and insurance: arrange commercial property insurance to take effect at closing, and transfer utility accounts promptly. Your lender will require proof of insurance before releasing funds.

Occupancy: in some transactions, particularly where the vendor is also a tenant winding down their occupancy, there will be a period between the legal closing and the date you can take physical possession. These arrangements should be documented carefully in the Agreement of Purchase and Sale before you sign.
