Capital gains on rental property is one of the most significant tax events an Ontario landlord will ever face, and it catches more people off guard than it should. If you bought a property in Belleville, Cobourg, or Oshawa ten or fifteen years ago, you may be sitting on a gain of several hundred thousand dollars without fully appreciating what that means for your tax bill the year you decide to sell. The profit you earn when you sell a rental property is not treated the same as employment income, but it is still taxable, and the rules changed meaningfully in 2024.
This guide walks through how capital gains tax on rental property works in Ontario, what your adjusted cost base is and why it matters, how the 2024 federal inclusion rate changes affect landlords holding significant equity, and what legal steps you can take now to reduce your eventual exposure. At Blue Anchor, we manage long-term residential rentals across Central Ontario, and while we are not accountants or tax lawyers, we work alongside landlords every day who are making decisions about their portfolios with one eye on the eventual exit. We have seen firsthand how much money gets left on the table by landlords who did not plan ahead. Please treat this guide as a starting point, not a substitute for advice from a qualified tax professional.
How Capital Gains on Rental Property Work in Canada
When you sell a rental property for more than you paid for it, the difference between your sale price and your adjusted cost base is your capital gain. Canada does not tax the full gain as income. Instead, only a portion of the gain, called the inclusion rate, is added to your taxable income for the year and taxed at your marginal rate.
For decades, the inclusion rate sat at 50 percent. That meant if you sold a rental property and realized a $300,000 gain, only $150,000 would be added to your income. At a combined federal and Ontario marginal rate of roughly 46 percent for higher earners, that translated to a tax bill of approximately $69,000. Significant, but manageable with planning.
The 2024 federal budget proposed increasing the inclusion rate to two-thirds (approximately 66.67 percent) for capital gains above $250,000 realized by individuals in a single calendar year, and for all capital gains realized inside corporations and trusts regardless of amount. Using the same $300,000 gain example, the first $250,000 would still be included at 50 percent, but the remaining $50,000 would be included at two-thirds, resulting in a higher overall tax bill. For landlords holding properties inside a corporation, the change is even more impactful because the two-thirds rate applies to every dollar of gain, not just the portion above $250,000.
The legislation has faced political uncertainty, and the status of the proposed changes should be confirmed with your accountant as of the date you are reading this. What is not uncertain is that the direction of travel is toward higher inclusion rates, and landlords with significant unrealized gains need to be thinking about this now rather than the week before they list.
Understanding Your Adjusted Cost Base
Your adjusted cost base, or ACB, is the foundation of every capital gains calculation. It is not simply what you paid for the property. It includes your original purchase price plus a range of costs that many landlords forget to track.
Costs that increase your ACB typically include legal fees paid on purchase, land transfer tax, real estate commissions paid when you bought the property, and the cost of capital improvements made over your ownership period. That last category is where Ontario landlords most commonly leave money on the table. A new roof, a furnace replacement, a kitchen renovation, an addition, a new deck, upgraded electrical panel work, or a finished basement all qualify as capital improvements that increase your ACB and reduce your eventual capital gain. Routine repairs and maintenance, by contrast, are deductible as current expenses against your rental income but do not increase your ACB.
The Canada Revenue Agency draws a clear line between a capital improvement, which adds value or extends the useful life of the property, and a repair, which simply restores something to its original condition. Replacing a broken window is a repair. Replacing all the windows in the building with new energy-efficient units is likely a capital improvement. Patching a section of roof is a repair. Replacing the entire roof is a capital improvement. The distinction matters enormously over a long holding period.
At Blue Anchor, we strongly encourage the landlords we work with to keep a dedicated folder, whether physical or digital, for every invoice, permit, and receipt related to capital work done on their properties. When you sell a property you have owned for twenty years, reconstructing that paper trail from memory is nearly impossible. Our property management records can help document the timeline of major work, but the invoices themselves need to come from you.
Capital Gains on the Sale of Rental Property: The CCA Recapture Problem
There is a second tax issue that often surprises landlords when they sell, and it is separate from capital gains entirely. If you have claimed Capital Cost Allowance, or CCA, on your rental property over the years, you may face recapture of that CCA when you sell.
CCA is the depreciation deduction available to rental property owners under the Income Tax Act. Many landlords claim it to reduce their taxable rental income each year. The problem is that when you sell the property, the CRA compares the proceeds of disposition to the undepreciated capital cost of the property. If the sale price exceeds the undepreciated capital cost, the difference up to the original cost of the depreciable property is recaptured and included in your income in the year of sale, taxed at your full marginal rate, not at the capital gains inclusion rate. This can create a very large and unexpected tax bill in the year of sale.
Whether or not to claim CCA is a strategic decision that should be made with your accountant each year, not just at tax time. For some landlords, the annual tax savings from CCA are worth the recapture risk. For others, particularly those planning to sell within a few years, it may make more sense to leave CCA unclaimed.
Legal Strategies to Reduce Capital Gains Tax on Rental Property in Canada
The question we hear most often from landlords thinking about selling is how to avoid capital gains tax on rental property in Canada. The honest answer is that you cannot avoid it entirely if you have a genuine gain, but there are several legal strategies that can reduce your exposure or defer the tax.
The most straightforward strategy is maximizing your ACB through diligent record-keeping, as described above. Every dollar you can add to your cost base is a dollar that does not get taxed as a capital gain. Over a long ownership period, this can amount to tens of thousands of dollars in legitimate tax savings.
A second strategy is timing the sale carefully. Because capital gains are reported in the year of sale, selling in a year when your other income is lower, for example after retirement or during a year with significant deductible losses, can reduce the marginal rate applied to the included gain. Spreading a sale across two tax years through a vendor take-back mortgage or installment sale arrangement is another option, though it introduces its own complexity and risk.
A third consideration is the principal residence exemption. If you lived in the property as your principal residence for some of the years you owned it, you may be able to shelter a portion of the gain from tax using the principal residence exemption. The formula is straightforward: the exempt portion of the gain equals the gain multiplied by the number of years the property qualified as your principal residence divided by the total number of years you owned it. Landlords who converted a former home into a rental, or who moved into a rental property before selling, should discuss this with their accountant carefully.
A fourth option for some landlords is a Section 85 rollover into a corporation, which can defer the recognition of the gain. This is a complex transaction with significant legal and accounting costs, and it is not appropriate for everyone. It also does not eliminate the tax, it defers it. For landlords already holding properties inside a corporation, the 2024 inclusion rate changes make the corporate structure less advantageous than it once was for capital gains purposes, which is another reason to get current advice.
Finally, some landlords explore gifting or transferring properties to family members at fair market value, which triggers a deemed disposition and immediate capital gains tax, or through estate planning mechanisms that defer the gain until death. Ontario does not have a provincial estate tax, but the deemed disposition at death under federal rules means the gain will eventually be realized. Proper estate planning, including the use of trusts or joint ownership structures, can manage how and when that happens.
How Rental Income Interacts With Capital Gains
It is worth clarifying a point of confusion that comes up regularly. Capital gains on rental income is not really the right framing. Rental income and capital gains are two separate categories of income under the Income Tax Act. Rental income is the rent you collect each month, minus allowable expenses like mortgage interest, property taxes, insurance, management fees, and repairs. That net rental income is taxed at your full marginal rate each year.
Capital gains on rental property arise only when you sell the property. The two streams of income are calculated and taxed separately. A landlord can have strong rental income and a large capital gain in the same year, and both are reported on the same tax return but through different schedules.
One area where they do interact is through the CCA recapture issue described above. Beyond that, managing your rental income efficiently through good expense tracking is important for its own reasons, quite apart from capital gains planning. Our post on tax deductions for rental property owners in Ontario covers the rental income side of the equation in more detail.
What Ontario Landlords Should Be Doing Right Now
At Blue Anchor, we manage properties across Belleville, Trenton, Quinte West, Cobourg, Oshawa, Port Hope, and Picton, and in our experience, the landlords who are best positioned financially when they sell are the ones who treated their rental as a business from day one. That means keeping organized records, tracking capital improvements, working with an accountant who understands real estate, and revisiting their tax strategy every few years rather than only when a sale is imminent.
If you are holding a rental property in Central Ontario and have not reviewed your ACB or your CCA position recently, now is a good time to do that. The 2024 inclusion rate changes, even if their final form is still being sorted out politically, signal that the federal government is paying closer attention to capital gains from investment properties. Getting ahead of that is far better than reacting to it.
Good property management also plays a role in your long-term financial outcome. A well-managed property attracts better tenants, experiences fewer costly disputes, and maintains its condition, all of which support a stronger sale price when the time comes.

Frequently Asked Questions
Do I pay capital gains tax when I sell a rental property in Ontario?
Yes. When you sell a rental property in Ontario for more than your adjusted cost base, the profit is a capital gain and is partially included in your taxable income for that year. The inclusion rate determines how much of the gain is taxable. As of the time of writing, the inclusion rate is 50 percent for individuals on gains up to $250,000 in a year, with proposed changes that would increase it to two-thirds above that threshold. Confirm the current rules with your accountant before making any decisions.
How is capital gains tax on investment property calculated?
Start with your sale price, subtract your adjusted cost base (purchase price plus buying costs plus capital improvements), and the result is your capital gain. Multiply that by the applicable inclusion rate to get the taxable capital gain, which is then added to your other income for the year and taxed at your marginal rate. Do not forget to account for CCA recapture separately if you have claimed depreciation on the property.
Can I avoid capital gains tax on a rental property in Canada?
You cannot legally avoid capital gains tax if you have a genuine gain on the sale of a rental property, but you can reduce it through strategies like maximizing your ACB with documented capital improvements, using the principal residence exemption for years the property was your home, timing the sale to a lower-income year, or structuring the sale to spread proceeds across tax years. A qualified tax professional can help you identify which strategies apply to your situation.
What is the difference between capital gains and rental income for tax purposes?
Rental income is the money you collect from tenants each month, taxed annually at your full marginal rate after allowable deductions. Capital gains arise only when you sell the property and are taxed at a lower effective rate because only a portion of the gain is included in income. They are reported separately on your tax return and calculated independently, though CCA claimed against rental income can create recapture taxed as ordinary income when you sell.
Does a property management company affect my capital gains when I sell?
Not directly. Property management fees are a deductible expense against your rental income, not a capital cost, so they do not increase your ACB. However, a well-managed property tends to be better maintained, which can support a higher sale price and reduce the cost of pre-sale repairs. Professional management also ensures your records, lease history, and maintenance documentation are organized, which buyers and their lawyers will want to review.
A Final Word
Capital gains tax on the sale of a rental property is not something to figure out the week you accept an offer. The decisions you make throughout your ownership period, from how you track capital improvements to whether you claim CCA to how you structure ownership, all feed into the tax outcome you face at the end. Ontario landlords who treat their rental properties as serious long-term investments, with proper records and regular professional advice, consistently come out ahead.
