Capital Gains On Real Estate In Canada (2026): What You’ll Actually Pay

Capital gains on real estate is one of the most-misunderstood corners of Canadian tax. The rules look simple from a distance — “your home is tax-free, your rental isn’t” — but the details are where people get burned. Here’s how it actually works in 2026.

The principal residence exemption (still intact)

If a property was your principal residence for every year you owned it, the gain on sale is fully tax-exempt. No matter how much you bought it for, no matter how much you sold it for, no tax owed. This is the single biggest tax break in Canadian personal finance.

The fine print:

• Only one principal residence per family per calendar year (you, your spouse, and minor children count as one unit)
• It must be ordinarily inhabitedby you or a family member — not just designated on paper
• You must report the sale on Schedule 3 of your tax return, even if no tax is owed. Skip this and CRA can deny the exemption.

The 12-month rule (a 2023 change that bit a lot of flippers)

Since January 1, 2023, if you sell a residential property within 365 days of buying it, the gain is treated as business income— not a capital gain — and the principal residence exemption doesn’t apply, even if you actually lived there.

Business income is fully taxable at your marginal rate (no 50% inclusion rate), so the difference is enormous. On a $100,000 gain in Ontario, you might pay roughly $20K under capital gains rules vs. $40-50K under business income rules.

Limited exceptions exist for “life events” — death, divorce, job relocation 40+ km, serious illness, household additions, threats to personal safety. Outside those, the rule is effectively a flipping deterrent.

How capital gains work on rentals and second properties

On any property that wasn’t your principal residence (rental, cottage, investment), you owe tax on the gain when you sell. The math:

1. Calculate the gain: sale price minus purchase price minus eligible costs (legal fees, real estate commission, capital improvements)
2. Apply the inclusion rate: in 2026, the inclusion rate is 50% on the first $250,000 of net annual capital gains, then 66.67% on amounts above that
3. Add the included portion to your taxable income for the year
4. Pay tax at your marginal rate

Worked example. You bought a rental in 2018 for $500K, sold it in 2026 for $850K. You spent $30K on capital improvements over the years. Eligible commission and legal costs at sale: $40K. Capital gain = $850K − $500K − $30K − $40K = $280K.

• First $250K at 50% inclusion = $125K added to taxable income
• Remaining $30K at 66.67% inclusion = $20K added to taxable income
• Total added to taxable income: $145K
• Approximate tax owed in Ontario at top marginal rate: $77K

The deferred-rate-hike status

In 2024, the federal government proposed raising the inclusion rate for gains over $250,000 to 66.67%. That hike was deferred and ultimately deferred again, and is currently scheduled to take effect in subsequent fiscal years — details continue to evolve. Watch the news for federal budget announcements that could shift this.

The change-of-use rule (a quiet trap for landlords)

If you convert your principal residence into a rental (or vice versa), CRA treats it as a deemed sale at fair market value on the day of the change of use. You may owe capital gains tax even though no money changed hands.

There’s an election under section 45(2) of the Income Tax Act that lets you defer this and continue to designate the property as your principal residence for up to 4 more years — but it has to be filed correctly and on time. Talk to a tax accountant before changing the use of any property.

What about cottage / vacation property?

A cottage canqualify for the principal residence exemption — but only if you designate it as your principal residence for the years you owned it (which means no other property in your family is the principal residence for those same years).

Most families with a primary home and a cottage do the math: typically the principal residence designation is used on whichever property appreciated faster on a per-year basis to minimize total tax. That’s a tax-accountant exercise.

How to plan around capital gains

• Document everything. Keep records of original purchase price, every dollar spent on capital improvements (kitchens, additions), legal fees, and selling costs. The lower your reported gain, the lower your tax.
• Time the sale if you have flexibility. Spreading a large gain across two tax years can keep both portions under the $250K threshold.
• Consider the 12-month rule on every transaction. If your purchase was less than 365 days ago, the math changes dramatically.
• Talk to a tax accountant before any non-principal-residence sale. Real estate gains are big enough that an hour of professional advice usually pays for itself many times over.

Bottom line

I’m a Realtor and a Mortgage Agent — not a tax accountant. For an investment property sale, your tax accountant is the most important person at the table. But knowing the rough shape of the tax before you list helps you negotiate the price, time the closing, and plan for the cash you’ll need to set aside.

Considering selling a rental, second property, or investment property? Send me the details and I’ll help you work backwards from the after-tax outcome you actually want.
