Selling a rental property in Canada isn't like selling a home you live in — there's no automatic tax exemption waiting for you. When you sell an income property, the profit is generally taxed as a capital gain. Understanding exactly how that works — and the legal strategies to reduce it — can save Ottawa landlords tens of thousands of dollars. Here's your complete 2026 guide.
When you sell a rental property, the profit — the difference between what you paid (your "adjusted cost base") and what you sell it for — is generally taxed as a capital gain, not as regular income. The key advantage: only a portion of that gain is taxable.
Capital Gain = Selling Price − Selling Costs − Adjusted Cost Base (ACB)
Taxable Capital Gain = Capital Gain × Inclusion Rate
Tax Owing = Taxable Capital Gain × Your Marginal Tax Rate
Important: Routine repairs and maintenance (repainting, fixing a leak) are not added to your ACB — but they ARE deductible against rental income in the year you incur them. This distinction matters a lot.
Not all of your capital gain is taxable. The inclusion rate determines what fraction gets added to your income. For 2026, only half (50%) of your capital gain is subject to tax for most individuals.
In this example, $80,000 gets added to your other income for the year and taxed at your marginal rate. For a landlord in a 40% marginal bracket, that's roughly $32,000 in tax — a meaningful number worth planning around.
| Capital gain | Taxable (50%) | Tax at 40% marginal rate |
|---|---|---|
| $100,000 | $50,000 | $20,000 |
| $160,000 | $80,000 | $32,000 |
| $300,000 | $150,000 | $60,000 |
The principal residence exemption (PRE) is the single biggest tax break in Canadian real estate — it lets you sell your primary home completely tax-free. But it does not automatically apply to rental properties, and Ottawa landlords need to understand its boundaries.
If you move out of your home and start renting it, you can file a subsection 45(2) election with the CRA to keep treating it as your principal residence for up to four years while it's rented. This can eliminate the capital gain for that period. There are strict conditions — you can't claim another property as your principal residence during that time — so consult a tax professional before relying on it.
Key warning: You can never claim the principal residence exemption on a property you bought purely as an investment and never lived in. For most Ottawa rental properties, capital gains tax will apply on sale.
None of these are loopholes — they're legitimate, CRA-recognized planning strategies. Always confirm details with a qualified accountant.
Many landlords claim Capital Cost Allowance (CCA) — depreciation on the building — each year to reduce rental income tax. That's fine while you own it, but here's the catch: when you sell, the depreciation you claimed is "recaptured" and taxed as regular income, not as a more favourably-treated capital gain.
Strategic tip: Whether to claim CCA is a genuine strategic decision, not a simple tax break. If you expect significant appreciation, deferring CCA may save money overall. If you plan to hold long-term and want the cash-flow benefit now, CCA can still make sense. This is a classic "ask your accountant" scenario.
