How to Avoid Capital Gains Tax on Property in Canada?

You can legally avoid capital gains tax on property in Canada by claiming the principal residence exemption on the home you live in. For a rental, cottage, or investment property, you can shrink the tax by raising your adjusted cost base, using capital losses, spreading the gain with a five year reserve, and moving property to a spouse at cost. Only 50 percent of a capital gain is taxable in Canada. A few rules can wipe out these savings, like the 365 day flipping rule and the deemed sale at death.

This guide explains how to avoid capital gains tax on property in Canada with the forms, rates, and deadlines CRA actually uses.

What Is Capital Gains Tax on Property in Canada?

Capital gains tax applies when you sell property for more than you paid for it. CRA calls the difference a capital gain, and 50 percent of that gain gets added to your income for the year. The federal government planned to raise this to two thirds, but it cancelled the change in March 2025, so the 50 percent inclusion rate still applies in 2026.

Here is how the math works. You buy a rental condo for $400,000 and sell it for $600,000. The gain is $200,000. Half of it, $100,000, goes on your T1 return as a taxable capital gain. At a 43 percent marginal rate, you owe about $43,000.

Your province changes the final number. Our guides on capital gains tax on real estate in Ontario and capital gains tax on real estate in Alberta show how provincial brackets affect the bill. For the wider picture, see our overview of real estate tax in Canada.

How to Avoid Capital Gains Tax on Property in Canada Legally?

Each method below follows the Income Tax Act and uses rules CRA publishes itself.

1. Claim the Principal Residence Exemption

The principal residence exemption is the only way to pay zero capital gains tax on property. It covers a house, condo, cottage, or mobile home that you or your family ordinarily lived in during the year.

Each family unit, meaning you, your spouse, and your children under 18, can designate only one principal residence per year. When you sell, you report the sale on Schedule 3 and file Form T2091(IND). CRA uses the “plus one” formula: years designated plus one, divided by years owned, times the gain. If you owned a cottage for 10 years and designate it for 6, then 7 out of 10, or 70 percent, of the gain is tax free.

2. Use the Change in Use Election

When you move out and rent your home, CRA treats it as sold at fair market value. A subsection 45(2) election stops that deemed sale. You attach a signed letter to your return for the year of the move, and the home keeps its principal residence status for up to four more years while it earns rent.

The trade off is that you cannot claim capital cost allowance on the building during those years. The rent stays taxable, but you can still deduct mortgage interest, property tax, and repairs, as our guide on how to claim rental property tax deductions explains.

3. Raise Your Adjusted Cost Base

Your gain is the sale price minus your adjusted cost base (ACB) and your selling costs. A higher ACB means a smaller gain. Many sellers overpay because they only count the purchase price. Add these costs:

• Land transfer tax and legal fees paid when you bought the property
• Capital improvements such as an addition, a finished basement, or a full kitchen renovation
• Real estate commission and legal fees paid when you sell

Regular repairs and maintenance do not count. Keep every receipt, since CRA asks for them during a review.

4. Offset the Gain with Capital Losses

Capital losses cancel capital gains dollar for dollar. If you sold stocks or crypto at a loss, that loss reduces your property gain. Unused net capital losses carry back three years using Form T1A, or forward with no time limit.

A common year end move is to sell a losing investment before December 31 in the same year you sell property. Do not buy the same investment back within 30 days, or the superficial loss rule cancels the loss. Our guide on how to reduce your year end tax bill in Canada covers more of these moves.

5. Spread the Gain with a Capital Gains Reserve

When you sell with a vendor take back mortgage, the buyer pays you over several years. That lets you claim a capital gains reserve under section 40(1)(a)(iii).

You report the gain as the money arrives, with at least 20 percent included each year, so the full gain lands within five years. A $200,000 gain spread over five years keeps each year in a lower bracket.

6. Time the Sale and Use Your RRSP Room

A sale in a year when your income drops, like the year after you retire, puts the taxable half in a lower bracket. An RRSP contribution works the same way.

A $30,000 contribution in the year of sale offsets the tax on $60,000 of capital gain, since only half of the gain is taxable.

7. Plan Transfers to Your Spouse and Children

Under subsection 73(1), you can move property to your spouse or common law partner at your ACB with no tax at transfer. Attribution rules send any later gain back to you, so the real benefit shows up at death, when a spousal rollover delays the tax until the survivor sells.

A gift to an adult child works the opposite way. CRA treats it as a sale at fair market value, and you owe tax on the full gain. Families who want these transfers done correctly work with estate planning in Toronto before any deed changes hands.

Rules That Can Cancel Your Tax Savings

Three situations push a property sale outside the normal capital gains rules.

1. The 365 Day Flipping Rule

Since January 1, 2023, profit on a home owned for less than 365 days counts as business income. That means 100 percent of it is taxable, and the principal residence exemption is gone. Exceptions cover death, disability, a new child, separation, job relocation, insolvency, and personal safety.

Our breakdown of the new CRA rules on housing units held for less than 365 days explains each exception, and the same rule applies to an assignment sale in Canada.

2. Selling as a Non-Resident

People who live outside Canada cannot designate a principal residence for years they were non-residents, and the “plus one” year disappears if you were a non-resident in the year you bought the home. Canadian real estate is also left out of departure tax, so the gain gets taxed later when the property sells. Until then, rent faces 25 percent Part XIII withholding on the gross amount, unless you file Form NR6 and make a Section 216 election to pay tax on net rent instead.

When you sell, the buyer holds back 25 percent of the price until you get a certificate of compliance from CRA through Form T2062. That holdback rises to 50 percent on the building portion of a rental. Form T2062 is due within 10 days of closing, and a late filing costs $25 per day, up to $2,500. Our guide for non-residents selling Canadian real estate covers the full timeline.

3. Deemed Disposition at Death

Death is the one sale nobody plans for. CRA treats every capital property you own as sold at fair market value right before death, and the tax goes on your final T1 return. That includes a rental property, a cottage, and a non-registered investment account. On a rental building, the deemed sale also triggers recapture of past capital cost allowance, and that amount is taxed as full income.

The executor can still claim the principal residence exemption on the family home by filing Form T2091(IND) with the final return. The final return is due April 30 of the following year, or six months after death if it happens between November 1 and December 31.

Capital Gains Tax at Death and Estate Planning

A cottage that grew from $250,000 to $850,000 creates a $600,000 gain and $300,000 of taxable income on a single return. Our guide to deemed disposition rules in Canada explains how CRA calculates it. If you leave the property to a spouse or a spousal trust, subsection 70(6) rolls it over at cost, and no tax applies until the survivor sells or dies.

RRSPs follow a similar pattern. If you want to know what happens to your RRSP when you die in Canada, the full balance becomes income on the final return unless it rolls to a spouse or a financially dependent child. An RRSP and a cottage gain on the same return can push an estate into Ontario’s top combined rate of 53.53 percent.

One of the most common estate planning mistakes is adding an adult child to the title to skip probate. If the child receives a real ownership share, CRA treats that share as sold at fair market value, and the home becomes exposed to the child’s creditors and divorce. Probate costs also differ by province. Ontario charges Estate Administration Tax of 1.5 percent on estate value above $50,000, while Alberta caps probate fees at $525. Families using estate planning in Calgary get plans built around those local rules.

Plan Before You Sell or Pass On Property

The principal residence exemption is the strongest tool to avoid capital gains tax on property in Canada, and the other methods shrink or delay whatever gain is left. Most of the savings come from decisions made before the sale: which property to designate, when to sell, and who inherits it. A sale that closes in January instead of December moves the gain into a different tax year. A cottage left to a child instead of a spouse loses the rollover under subsection 70(6).

Start with your purchase documents, receipts for every capital improvement, and a list of the years each property was your home, since those records support every designation CRA asks about.
