There’s no 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. Whether you held the shares for nine days or nine years, the gain is worked out the same way.
Only a part of the gain is normally taxable. The CRA’s page on capital losses and deductions states that the inclusion rate for 2025 is 50%. We couldn’t find a separate 2026 rate written on a CRA page, so we’re assuming 50% again, which fits the government’s announcement 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, enough to hurt.
It’s a ballpark. The estimate uses basic personal amounts only, and it includes Ontario’s surtax and health premium the way the engine models them, so expect your own return to land 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, as the $1,482 and $2,965 above show.
One last practical point for tax time: if you made several quick trades in the same stock, don’t net them in your head. List each sale separately, add them up, and let the form do the netting.
What records should you keep for each trade?
For every sale, note what you paid, what you sold for, the date of each, and any commission or fee. Those numbers decide your gain, and a day trader’s year can mean hundreds of lines. Most brokers give you a statement at year end, but check it against your own notes, especially after a transfer between brokers when the original cost can get lost.
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. A net capital loss can go back three years or forward with no end date, but only against taxable capital gains, never against your salary. Buying the same shares back within 30 days of selling can get the loss denied, so a quick in-and-out trade is the wrong place to hunt for a tax break. Do you really want to trade just to save a few bucks?
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 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. No level of government runs or endorses this site.
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.
