Commercial property

Selling commercial property in Ottawa — an introduction

What a commercial buyer will scrutinise, and the preparation that decides your price.

Last verified: July 24, 2026

What you are actually selling

The buyer is buying your leases

A house sells on comparison. A commercial building sells on the income it produces and how dependable that income looks to someone who has never met your tenants. The building matters, but it is the leases that set the number.

That has a practical consequence sellers often realise too late: the work that raises your price happens in the year before the sale, not in the month before it. A lease renewed for five years with a solid tenant, an ambiguous clause cleaned up, an operating cost properly recovered — these change the income and therefore the value. Staging does not.

Before you list

Assemble the file a buyer will demand

Commercial due diligence is documentary, and a seller who cannot produce documents looks like a seller with something to hide — even when they are merely disorganised. Expect to provide, and therefore to gather first:

  • Every lease, and every amendment — including the side letters and verbal arrangements someone will eventually remember. Gaps here kill deals late, which is the expensive time for a deal to die.
  • A rent roll and the payment history behind it — who pays what, on what term, and who actually pays on time.
  • Operating statements for several years, with the one-off items identified as one-off rather than buried.
  • Environmental reports if any exist. If the site's history invites the question, a buyer will ask it; knowing the answer first is better than discovering it during their diligence.
  • Building condition, service records and capital history — roof, HVAC, structure, and what has been deferred.
  • Zoning and compliance — permitted use, any legal non-conforming status, outstanding work orders.

Estoppel certificates deserve a specific mention: a buyer will typically require each tenant to confirm in writing the terms of their own lease. If your records and your tenants' understanding differ, you want to find that out while you still have time to reconcile it.

The part that surprises people

Tax is a planning decision, not a closing detail

The principal residence exemption that shelters many home sales has nothing to do with this. A commercial disposition can bring capital gains and — where you have claimed depreciation over the years — recapture, which lands as ordinary income in the year of sale and regularly catches owners who budgeted only for the gain.

How the deal is structured matters too. Selling the property is not the same transaction as selling the company that owns it, and the better answer depends on facts we cannot see. HST treatment on commercial real property is its own subject with its own rules.

None of that is something to resolve after you have signed. Talk to your accountant before you agree a structure — the difference between two defensible approaches can be substantial, and only one of them is still available before the offer is accepted.

Timing and buyers

A smaller pool, and a slower one

Expect a different rhythm from a house sale. The buyer pool is smaller and more analytical, diligence periods are longer, financing conditions are real conditions rather than formalities, and a sale can take months rather than weeks. Pricing is an evidence exercise built from income and comparable transactions, and buyers will build their own model regardless of what your listing says.

Choose representation accordingly: a commercial agent who works your specific submarket will read the building the way its buyers will.
