This is three decisions stacked on top of each other
The question "should my corporation buy the building" bundles three separate decisions, and they have to be made in order. First: should your business own its premises at all, or keep renting. Second: if you buy, which entity should take title, the operating company, a holding company, or you personally. Third: how should the purchase be financed, because the lender's requirements will constrain the first two answers. Owners get into trouble when they collapse these into one, usually by falling for a building first and reverse-engineering the justification afterward.
The order matters because each decision sets the terms for the next. If the business cannot afford to own, the structure question never arises. If the right structure is a holding company landlord, the financing conversation changes, because the lender is now underwriting a rent-collecting entity backed by your operating company's lease and your guarantee. We walk through all three below, and where a question deserves its own page, we point to it rather than compress it.
It is also worth naming what the question is really about, because for most owners it is not premises at all. It is where the retained earnings should go. A business that has been profitable for years accumulates cash inside the corporate group, and the building question is one of three or four competing uses for it, alongside expansion, acquisitions and an investment portfolio. Framed that way, the building has to win on its merits against the alternatives, not just against the rent cheque.
Decision one: own or keep renting
Owning wins when the business is stable, the location genuinely matters for the long term, and the total cost of ownership is close to the rent you would otherwise pay, because then every mortgage payment builds equity in an asset you control instead of your landlord's. Renting wins when the business is still moving, growing fast, likely to relocate, or able to earn more by putting its capital into inventory, people or equipment than into real estate. A building is a second business bolted onto your first one, with its own financing, maintenance, insurance and eventually its own sale, and it deserves to be evaluated as one.
Make the comparison honest on both sides. The ownership column should carry a realistic maintenance reserve, property management time that currently belongs to your landlord, and the roof and HVAC that will eventually be yours to replace; the renting column should carry the escalations your next renewal will actually bring, the leasehold improvements you keep paying for in space you do not own, and the risk that the landlord's plans, not yours, decide when you move. Owners tend to flatter whichever column they have already decided on, which is exactly why the numbers should be built by someone without a favourite.
| What you are weighing | Keep renting | Corporation buys the building |
|---|---|---|
| Cash needed up front | Deposit and leaseholds only | Down payment, land transfer tax, legal, appraisal and inspection costs |
| Monthly cost behaviour | Rises at each renewal, at the landlord's option | Largely fixed for each mortgage term, then rate-dependent at renewal |
| Where the capital works | Free to fund inventory, people, equipment, acquisitions | Locked into the property until you refinance or sell |
| Flexibility to move or grow | High; walk at lease end | Low; you move when the building sells or re-leases |
| Long-run outcome | Rent is gone; no asset | Equity builds; the building can outlast and outgrow the business |
The affordability test underneath this is the one the bank will run: does the cash flow the business reliably produces cover the mortgage payments, property tax, insurance, maintenance and utilities, with a cushion, after you have paid yourself. Run it on your real numbers, not the listing agent's, and stress it for a slow year and a higher renewal rate. If ownership only works in the best year you have ever had, it does not work.
There is a longer-horizon argument for owning that deserves honest weight rather than dismissal: for many owner-managers the building becomes the retirement asset. Businesses are hard to sell and their value is tied to you; a decent commercial property is easier to value, easier to borrow against, and keeps paying rent after the business is sold or wound down. Plenty of owners have watched the building end up worth more than the company that occupied it. That outcome is real, but it is a reason to buy a good property with sustainable financing, not a reason to overpay for the one your business happens to sit in.
Decision two: which company signs the deed
Buying corporately beats buying personally for most owner-managers because of where the money comes from. A corporation earning active business income in Ontario pays combined tax of 12.2% on its first 500,000 dollars of profit, so a dollar of profit leaves roughly 88 cents available for a down payment. Pull that same dollar out as salary or dividends first and personal tax takes a far bigger bite before you ever reach the lawyer's office. When the building will be used by your own business, letting the corporate group buy it keeps the purchase in lightly taxed dollars, which is usually the single largest financial advantage in the whole decision.
Buying personally still makes sense in specific situations: when you want the building as a personal investment fully separated from the business, when you plan to hold it long after the business is sold, or when personal mortgage financing is materially easier for you to obtain. But personal ownership means funding with after-tax dollars, reporting the rent on your personal return, and running a formal landlord relationship with your own company, with a written lease, a defensible market rent, and HST charged and recovered on every cheque. Whichever entity ends up on title, if it is not the operating company itself, that landlord-and-tenant machinery comes with it, and it has to be run properly from the first month.
The route the money takes matters as much as the destination. Profits earned in the operating company can generally move to a holding company as intercompany dividends without personal tax along the way, which is how a down payment saved inside the opco ends up funding a purchase made by the holdco. That plumbing has technical conditions and it needs to be run before closing, on advice, but it is the reason the corporate group can bring far more purchasing power to the table than the same owner buying personally: the money arrives at the lawyer's trust account having paid only the low corporate rate, not the full personal rate.
Inside the corporate route, the sharper question is opco versus holdco. Title in the operating company is simple, but it parks a valuable asset inside the entity that carries all the business risk, and it can complicate a future sale of the business, including your access to the lifetime capital gains exemption, because a building-heavy balance sheet changes what a buyer is buying. Title in a holding company or a dedicated property company keeps the real estate outside the line of fire and lets the business sell separately from the building. That decision has enough moving parts that we gave it its own page: personally, opco or holdco, who should own the building.
Decision three: the financing, and how the lender narrows your choices
The lender gets a vote on your structure, and it votes early. A commercial mortgage on an owner-occupied building is underwritten twice: on the property itself, and on the covenant of the business that will occupy it. The bank will want your corporate financial statements for the last two or three years, a debt service calculation showing earnings cover the proposed payments with a margin, financial projections if the purchase changes your cost base, and, almost always, your personal guarantee regardless of which company takes title. If the borrowing entity is a holdco with no operations, the lender will lean on the lease from your operating company and on covenants from both entities, and its ongoing lender reporting requirements, annual statements, sometimes covenant certificates, will apply across the group.
Plan the equity side as carefully as the debt side. Commercial lenders finance a percentage of the lesser of price and appraised value, so the down payment on a commercial building is materially larger than on a house, and it has to be genuine equity the lender can trace: retained corporate cash, a documented shareholder loan, or proceeds of another asset, assembled before the financing condition expires. Expect the approval to arrive with conditions attached, a current appraisal, often an environmental assessment, sometimes a building condition report, each with its own cost and lead time, which is why the conditional period in your offer needs to be negotiated with the lender's checklist in mind rather than the vendor's preferences.
Assembling that package is exactly the work of a business financing and projections CPA in Ontario: statements at the assurance level the lender expects, a projection that survives underwriting, and a structure the credit committee can say yes to. It is worth knowing before you offer that the choice of borrowing entity can change the pricing and terms you are offered, and occasionally a lender will push back on the structure you prefer; how to handle that negotiation is the subject of how financing affects commercial property ownership structure. For smaller purchases, government-backed small business loan programs can apply to real property, with their own eligibility limits, and are worth checking before you assume a conventional mortgage is the only route. Our financing support work covers the package end to end.
The tax life of a corporate-owned building, from closing day to sale day
Owning the building corporately changes your tax file in predictable ways, and it helps to see the whole arc before you commit. At purchase, the price is split between land and building; the building portion becomes depreciable property the corporation writes off gradually through capital cost allowance, while land is not depreciable. Ontario land transfer tax applies on closing, and on a commercial purchase the HST does not usually move as cash: an HST-registered corporate purchaser normally self-assesses the tax on its own return and claims the offsetting credit in the same filing, which is one of several reasons the purchasing entity must be registered correctly before closing, not after.
During ownership, the mortgage interest, property tax, insurance, maintenance and CCA are deductible against the income the building supports, but mortgage principal is repaid with corporate after-tax dollars, which is why the low corporate rate matters so much to the math. If the building sits in a holdco or property company, market rent flows from the operating company under the lease, moving profit into the entity that holds the asset and servicing the mortgage there. If the corporation rents part of the building to third parties, that rent is generally passive investment income, taxed at roughly 50% inside the corporation until dividends are paid, and enough passive income across an associated group can begin to grind the small business deduction. A building fully used in your own active business raises none of this; a building bought partly as a rental raises all of it, so the projections should be built on the tenancy mix you will actually have.
At the end, selling a corporate-owned building triggers its own stack: recapture of the CCA claimed, tax on the capital gain, a tax-free capital dividend account credit for the untaxed half of that gain, and HST mechanics on the sale. The exit deserves planning years before it happens, and we cover it fully in what tax issues arise when selling corporate-owned real estate. The point for today's decision is simple: the structure you choose at purchase is the structure you will sell from, and unwinding a wrong choice later is a designed transaction with real cost.
The facts that change the answer
Six facts decide whether your corporation should buy, and which corporation:
- The stability of the business. Ownership suits a business with a proven location and predictable cash flow; a business still finding its footprint should usually keep renting.
- The coverage math. Whether normalized cash flow carries the full cost of ownership with a cushion, in an average year, decides the question before any tax argument does.
- Where the down payment sits. Cash already inside the corporate group argues for a corporate purchase; funding personally means paying personal tax first just to get the money to the table.
- Your exit picture. If a sale of the business is plausible within ten years, keeping the building out of the operating company protects both the sale and the property.
- Who will occupy it. Fully owner-occupied is the clean case; renting space to third parties adds passive income, the small business deduction grind, and a landlord operation you must actually run.
- What the lender will accept. The financing structure, guarantees and reporting requirements can favour one ownership setup over another, so the term sheet belongs in the decision, not after it.
We run this decision as a single piece of work: affordability on your real numbers, the entity choice, the financing package and the closing checklist, either inside an ongoing engagement or as a defined-scope project.
