Start at the finish: on sale day, a building inside the opco becomes everyone's problem
The clearest way to test the structure is to imagine selling the business, because that is when the building's address stops being an accounting detail. Most buyers of an owner-managed business want the operations: the customers, the team, the equipment, the contracts. Very few want to finance a commercial property on top of the purchase price, so a building inside the operating company either shrinks your buyer pool or forces a carve-out on the eve of the deal, a transfer of the property out at fair market value, with tax on the accrued gain and Ontario land transfer tax, negotiated under deadline pressure at the worst possible moment.
The exemption tests add a quieter cost. Selling shares tax-free under the lifetime capital gains exemption, up to 1.25 million dollars of gain per shareholder, requires the company's assets to be substantially devoted to active business use at the time of sale, and to have stayed mostly so throughout the two years before. A building the business fully occupies counts as an active asset and does not offend the tests by itself. But businesses shrink, move and sublet, and the day part of the building is rented to strangers, that portion drifts toward passive status, eroding both the tests and the small business deduction. A building outside the opco simply never enters this arithmetic.
Separation also buys negotiating room the opco owner never has. With the building outside, you can sell the shares of the business and keep the property as a long-term income asset, lease it to the buyer at market rent, sell the two to different purchasers on different timelines, or hold the building for the family after the operating story ends. With the building inside, every one of those paths first requires prying the property out, on a deadline, at whatever tax cost the years have accrued. Buyers pay for clean lines, and lenders finance them more readily.
And exit aside, there is the ordinary risk case: everything the operating company owns stands behind everything the operating company does. A serious claim, a failed contract, an uninsured loss, and the premises are on the table with the rest. Held outside, the building survives an opco failure, and its owner is free to lease the space to whoever runs a business there next, including a reorganized successor.
"Outside the opco" means one of two addresses, and both work
Outside the operating company, the building normally lives in one of two places, and the choice is about fit rather than correctness. The first is the holding company that already sits above the opco, or is being created anyway; it owns the title and leases the premises down. The second is a sister realty company, a corporation beside the opco rather than above it, owned by you or by the holdco, whose only job is holding the property. Sister structures are common where different family members should own the building than the business, where lenders want the real estate ring-fenced from the group, or where the holdco is being kept clean for other reasons.
Either way, the arrangement runs on a real lease at a defensible market rent, actually invoiced and actually paid. The tax system cooperates with this: rent received from an associated corporation that uses the property in its active business is generally treated as active business income to the recipient rather than passive investment income, so the structure does not manufacture the passive income problem it might appear to. The opco deducts the rent it always effectively bore; the growth in the property accrues to its owner, outside the risk zone.
Running the two-company version is mostly routine once it is set up. Commercial rent carries HST, so the property company registers, charges the tax on each invoice, and the operating company recovers it as an input tax credit, which nets to nothing across the group while both sides stay registered and current. The property company claims capital cost allowance against its rent, files its own return and carries the mortgage, and the lease terms give the lender the covenant story it needs. None of this is exotic, but all of it must actually happen, because a lease that exists only in theory is the first thing a reviewer or opposing counsel will notice.
The choice between these addresses, and how the wider corporate structure should be arranged around them, is part of the larger holdco design question covered in holding companies for Canadian business owners and, at the decision level, in do I need a holding company for my operating business.
If the building is already inside, moving it out is a designed transaction
Here is where this decision differs sharply from most restructuring questions: shares reorganize cheaply, land does not. Adding a holding company above an operating company is a share exchange that section 85 keeps tax-deferred, but taking a building out of the opco means the title itself moves, and four separate frictions attach to that.
| Friction | Why it exists | What manages it |
|---|---|---|
| Income tax on the accrued gain | Moving the property to a related company is a disposition at fair market value | A section 85 tax-deferred rollover, electing at cost, with share consideration and a T2057 filed on time |
| Ontario land transfer tax | The tax follows registered transfers of land, related companies or not | Relief between closely related corporations exists but is narrow and conditional; often the tax is simply a real cost of the move |
| HST | A commercial property transfer is a taxable supply | With both companies registered before closing and the right elections in place, the tax is typically managed to a wash rather than a cash cost |
| The mortgage | Lenders must consent to their security changing hands | Consent, refinancing or assumption negotiated before anything is signed, not after |
The section 85 piece carries its own discipline. The elected amount is anchored to the property's tax cost, the shares taken back have their adjusted cost base and paid-up capital set by the rollover mechanics, and those ACB and PUC numbers are ground down deliberately by the rules so the transfer cannot manufacture tax-free withdrawal room. A defensible valuation of the property sits underneath all of it, because every number in the election is measured against fair market value.
One more number belongs in the long view: the building's own eventual sale. When the property company sells years later, half the capital gain is taxable at corporate investment rates and the other half is credited to the capital dividend account, from which it can be paid to shareholders tax-free; recapture of the depreciation claimed along the way arrives as taxable income beside it. That treatment is the same whichever company owns the title, but the proceeds land very differently: in a property company they arrive beside the rest of your planning, in the operating company they arrive inside the entity you may be trying to keep clean, right when cleanliness matters most.
Then comes legal implementation: the deed, the lease back to the opco, the corporate resolutions on both sides, HST registrations and elections, and the land transfer tax filings, executed in an order that matches the tax design. It is entirely doable, we run these as defined-scope projects, but nobody should pretend it is free. Which is the real argument of this page: the structure costs little to get right at purchase and real money to correct later, so the decision deserves an hour of analysis before the next closing, not after it.
When keeping the building inside the operating company is defensible
Honesty requires the other side of the ledger, because opco ownership is not a mistake in every file. It is defensible when most of the following are true: the business occupies essentially the whole building and will keep doing so, no sale of the company is realistic within a decade, the operating company's risk profile is genuinely modest, and the financing was materially better with one strong borrower carrying both the business and the real estate. A second corporation is a permanent annual cost in filings, fees and attention, and for a small, stable, low-risk business that owns its premises and plans to keep both forever, that cost can outweigh benefits it may never use.
What we push back on is opco ownership by default, the building bought in the operating company because that is where the bank account was the week the offer was accepted. The defensible version of this choice is made looking at the exit, the risk and the tax tests, and concluding they do not bite. The indefensible version is not a choice at all, and it is the one that produces the expensive eve-of-sale carve-outs described above.
If the property decision is being made as part of building the wider structure, the mechanics of stacking a holdco above the business, and what it costs to run one, are set out in how do you add a holding company above an operating company.
The facts that change the answer
Six facts decide where the building should sit, and most owners can answer them from memory:
- Your exit horizon. Any realistic sale of the business inside ten years argues strongly for the building living outside it, and the two-year look-back in the exemption tests rewards deciding early.
- Occupancy, now and later. Full occupancy by the business is clean anywhere; expected third-party tenants push the building out of the opco, where their rent would be passive income feeding the small business deduction grind.
- The risk profile of operations. The more plausibly the business could face a claim beyond its insurance, the more the premises need distance from it.
- Whether the building is already inside. An existing accrued gain, land transfer tax and the mortgage all raise the cost of moving, and sometimes the honest advice is to leave a long-held building where it is and fix the structure for the next purchase.
- The lender's terms. Financing offers can differ between a one-borrower and a two-company structure; the term sheet belongs in the analysis before title is decided.
- Family and estate intentions. If the building is meant to become the family's long-term asset while the business is eventually sold, separate ownership is nearly mandatory, and it opens the door to succession planning the opco could never host.
