Updated Checked by the Tax-Services.ca editorial team How we check
We couldn’t find a separate short term gains tax in Canada. The CRA’s capital gains pages send everyone through the same Schedule 3 and line 12700, and the ones we read mention no holding period. On a $10,000 gain, an Ontario earner on $80,000 pays about $1,482 in tax if it’s a capital gain, and about $2,965 if the CRA treats it as business income.
Is there a short term gains tax in Canada?
Searches for this phrase often come from the United States, where holding time changes the rate. Canadian returns work differently, so don’t carry those rules across. Here, a gain from selling property goes on Schedule 3, and the taxable amount lands on line 12700 of your return.
Only a part of the gain is normally taxable. The usual share is one half. We couldn’t find the 2026 inclusion rate written on a CRA page, so treat 50% as our working assumption rather than a confirmed figure. What we can confirm is that the government announced on 21 March 2025 that it was cancelling the proposed rise to two-thirds.
How is a quick sale taxed?
Your taxable gain is added to your other income for the year and taxed at your usual rates. Because it stacks on top, it lands at the highest rate you already pay. The federal rates for 2026 are below.
| Taxable income | Federal rate |
|---|---|
| Up to $58,523 | 14% |
| $58,523 to $117,045 | 20.5% |
| $117,045 to $181,440 | 26% |
| $181,440 to $258,482 | 29% |
| Over $258,482 | 33% |
Your province adds its own tax on top. The capital gains tax calculator does the whole sum, and the marginal tax rate calculator shows the rate on your next dollar.
What does a $10,000 gain cost in Ontario?
Say you earn $80,000 and sell shares for a $10,000 profit, half of it taxable. Your taxable income rises by $5,000 to $85,000. Using the tax engine behind our calculators, federal and Ontario tax together go up by about $1,482. You keep roughly $8,518.
Now count the same $10,000 in full as ordinary income, which is what business income would mean. Tax rises by about $2,965, so you keep about $7,035. That’s a difference of $1,483 on one trade.
Rough, of course.
The estimate uses basic personal amounts only, and it includes Ontario’s surtax and health premium the way the engine models them, which is a fair bit of machinery for one number, so expect your own return to land somewhere near it rather than on it.
When could quick trades be business income?
This is the part that catches people. Selling within days doesn’t make a gain fully taxable. But the CRA can look at how often you trade, how you go about it and what you meant to do, and decide you’re running a business. We couldn’t find a fixed number of trades or days on the CRA pages we read, so there isn’t a safe line to quote.
If you trade a lot, check the CRA’s guidance on business income before you file. If you sell now and then, it’s most likely a capital gain. And if you’re unsure, ask an accountant. It’s one of the few cases where the cost is worth it, because the answer can double the tax.
What if you sold at a loss?
Capital losses can offset capital gains, and the CRA has a page on carrying unused losses to other years. That’s the main reason to keep every trade record, including the ones that lost money. The details of when a loss is denied are outside this page, and we haven’t verified them.
If you’d rather hold shares inside registered accounts, the TFSA calculator and the RRSP calculator show how that money grows. Different rules apply inside them, so check the CRA pages for each account before you trade there.
Where do the numbers come from?
Federal brackets are from the Canada Revenue Agency’s 2026 tax rates page. Schedule 3 and line 12700 are explained on the CRA’s capital gains pages, and the Prime Minister’s news release of 21 March 2025 covers the cancelled rate rise. Our own arithmetic produced the dollar examples, so treat them as estimates. This website has no connection with the CRA or any government.
Frequently asked questions
Does Canada tax short term gains at a higher rate?
We found no separate short term rate on the CRA pages we read. A gain goes on Schedule 3 whatever the holding time, unless the CRA sees your trading as a business.
How much of a capital gain is taxable?
Normally one half, but we couldn't find the 2026 rate printed on a CRA page, so check before you rely on it. The rise to two-thirds was cancelled, announced on 21 March 2025.
Where do I report a gain?
On Schedule 3, with the taxable amount carried to line 12700 of your return.
Can I offset a gain with a loss?
Capital losses can be used against capital gains, and the CRA explains how to carry unused losses to other years.
Can frequent trading count as business income?
It can, depending on the facts. We found no set number of trades or days on the CRA pages we read.
