Capital Gains Tax in Ontario

Ontario is Canada’s most populous province and home to the Toronto Stock Exchange, making capital gains tax a key concern for the province’s large investor base. When you sell an asset — such as stocks, ETFs, mutual funds, or investment real estate — for more than you paid, the profit is a capital gain. In Canada, only 50% of your capital gain (the inclusion rate) is added to your taxable income. That taxable portion is then taxed at your combined federal and Ontario marginal tax rate.

Because Ontario’s top provincial rate reaches 13.16% — and the Ontario surtax pushes the effective top rate even higher — the province has one of the highest combined marginal tax rates in the country at 53.53%. This means the maximum effective capital gains tax rate for Ontario residents is 26.77%.

Tax Bracket Rate
First $52,886 5.05%
$52,886 – $105,775 9.15%

$150,000 – $220,000 12.16%
Over $220,000 13.16%

Ontario also applies a surtax on provincial tax exceeding certain thresholds: 20% of basic provincial tax over $5,315 and 36% of basic provincial tax over $6,802. This surtax effectively increases the marginal rate for higher-income taxpayers.

How Ontario Compares

Ontario’s top capital gains rate of 26.77% — inflated by the provincial surtax — places it among the highest in Canada. Here’s how Ontario stacks up against key comparison provinces:

Province Top Combined Rate Top CG Rate
Ontario 53.53% 26.77%
Quebec 58.75% 29.38%
Alberta 48.00% 24.00%
British Columbia 53.50% 26.75%

Capital Gains Tax Rates in Ontario

Because only 50% of a capital gain is taxable, the effective capital gains tax rate is half the combined marginal rate. Here are the effective capital gains tax rates at various income levels for Ontario residents:

Taxable Income Range Combined Marginal Rate Effective Capital Gains Rate
Up to $52,886 20.05% 10.03%
$52,886 – $57,375 24.15% 12.08%
$57,375 – $105,775 29.65% 14.83%
$105,775 – $114,750 31.48% 15.74%
$114,750 – $150,000 33.89% 16.95%
$150,000 – $220,000 37.91% 18.96%
Over $220,000 (top bracket) 53.53% 26.77%

The jump to the top bracket is significant due to the Ontario surtax. Taxpayers approaching this threshold should consider strategies to manage the timing of capital gains.

Worked Example: Capital Gains Tax in Ontario

Scenario: You are a Toronto tech worker earning $150,000 in employment income. You sell a rental condo for a $120,000 capital gain.

Step 1: Calculate the taxable capital gain

Amount
Total capital gain $120,000
Inclusion rate 50%
Taxable capital gain $60,000

Step 2: Determine which brackets the gain falls into

Your employment income of $150,000 already fills the lower brackets. The $60,000 taxable gain pushes your total taxable income from $150,000 to $210,000 — staying within Ontario’s fourth bracket (12.16%) but crossing a federal bracket boundary.

Income Range Amount Federal Rate Ontario Rate
$150,000 – $177,882 $27,882 26.00% 12.16%
$177,882 – $210,000 $32,118 29.00% 12.16%

Step 3: Calculate the tax

Component Calculation Tax
Federal tax $27,882 × 26% + $32,118 × 29% $16,564
Ontario base tax $60,000 × 12.16% $7,296
Ontario surtax (incremental) 20% over $5,315 + 36% over $6,802 on added base tax $4,086
Total tax on gain $27,946
Effective rate on $120,000 gain 23.29%

At this income level, the Ontario surtax adds meaningfully to the provincial tax. The same gain realized in Alberta would produce roughly $14,575 in tax — about $13,000 less — illustrating how Ontario’s surtax compounds the cost of large gains.

How to Reduce Capital Gains Tax in Ontario

Avoid the Surtax With RRSP Contributions

Ontario’s surtax dramatically increases the effective tax rate on capital gains for higher earners. A well-timed RRSP contribution in the same year you realize a large gain can pull your taxable income back below surtax thresholds. Because the deduction value is amplified at Ontario’s higher rates, each dollar contributed saves more here than in most other provinces.

Split Gains Across Calendar Years

The Ontario surtax creates a steep jump in effective rates once your provincial tax exceeds $5,315 and again at $6,802. If you control the timing of a sale — such as investment real estate or a stock portfolio — selling a portion before December 31 and the rest after January 1 can keep each year’s income below surtax territory, potentially saving thousands.

Claim the Principal Residence Exemption on Toronto Real Estate

Toronto-area property values have created enormous embedded gains for long-time homeowners. The principal residence exemption shelters the entire profit from tax when you sell the home you ordinarily inhabit. If you own both a city home and an Ontario cottage, only one can be designated per year — plan your designations carefully over your ownership period and file Form T2091 on sale.

Donating publicly traded stocks or ETFs directly to a registered charity eliminates the capital gains inclusion entirely. You also receive charitable donation credits at both the federal level and the Ontario level, and Ontario’s higher marginal rates make the provincial credit particularly generous for top-bracket taxpayers.

Ontario-Specific Tax Considerations

The Ontario Surtax

Ontario is one of the few provinces that levies a surtax on top of the basic provincial income tax. The surtax is calculated as 20% of basic provincial tax in excess of $5,315 plus 36% of basic provincial tax in excess of $6,802. This additional layer of tax is what pushes Ontario’s top combined marginal rate to 53.53% — one of the highest in Canada. For capital gains, this means Ontario’s top effective rate of 26.77% is notably higher than provinces like Alberta (24.00%) or Saskatchewan (23.75%).

Ontario Health Premium

The Ontario Health Premium is an additional levy based on taxable income, ranging from $0 (for income under $20,000) to $900 (for income over $200,000). While not technically a tax bracket, it adds to the overall tax burden for Ontario residents.

Real Estate Capital Gains in Ontario

Ontario’s real estate market, particularly in Toronto, has produced significant capital gains for property investors. Non-principal-residence properties such as rental units, cottages, and vacant land are subject to capital gains tax on sale. The province also levies a land transfer tax, and the City of Toronto adds a second municipal land transfer tax on purchases within city limits.

Ontario Trillium Benefit

Lower-income Ontario residents may qualify for the Ontario Trillium Benefit, which combines the Ontario Sales Tax Credit, Ontario Energy and Property Tax Credit, and Northern Ontario Energy Credit. A large capital gain in a single year could affect eligibility for these income-tested benefits.
