Canada’s Property Flipping Rule and the 365-Day Cliff
Canada’s residential property flipping rule does not ask what you intended when you bought. It deems. Sell a Canadian housing unit you have owned for 364 consecutive days and the profit is business income: no capital gain treatment, no principal residence exemption, taxed in full. Sell on day 365 and the ordinary analysis resumes. On a $150,000 profit for an Ontario resident with $90,000 of other taxable income, that single day is worth $66,028, on our arithmetic at 2026 rates.
Below is where that date falls, what crossing it costs, the nine life events that take a sale out of the rule, and why a pre-construction buyer and a British Columbia seller are each counting a different clock.
One day of ownership is worth $66,028 on a $150,000 profit. Combined federal and Ontario income tax by days of ownership, for a 2026 Ontario resident with $90,000 of other taxable income. Sources: Income Tax Act s.12(12) to 12(14), CRA Residential Property Flipping Rule, and CRA T4032ON January 2026 for the rates. Our arithmetic.
The rule deems, so there is nothing left to argue
The operative provision is subsection 12(12) of the Income Tax Act, section 12:
For the purposes of this Act, if, absent this subsection and paragraph 40(2)(b), a taxpayer would have had a gain from the disposition of a flipped property, then throughout the period that the taxpayer owned the flipped property (a) the taxpayer is deemed to carry on a business that is an adventure or concern in the nature of trade with respect to the flipped property; (b) the flipped property is deemed to be inventory of the taxpayer’s business; and (c) the flipped property is deemed not to be capital property of the taxpayer.
The opening clause is doing specific work. Paragraph 40(2)(b) is the principal residence exemption, and the rule names it in order to switch it off, which makes the size of what is being switched off the first thing worth knowing. Our explainer on capital gains when you sell your home covers the exemption itself and the years it has to cover.
The Canada Revenue Agency puts the consequence plainly on its Residential Property Flipping Rule page: “Where the new deeming rule applies, profits on the sale cannot be treated as a capital gain (50-per-cent income inclusion) and the Principal Residence Exemption is not available.” The rule applies “in respect of transactions occurring on or after January 1, 2023”.
Here is what those two sentences cost. Same taxpayer, same $150,000 profit, 2026 Ontario rates, federal and Ontario tax with the surtax and health premium, basic personal amount as the only credit.
| How the profit is taxed | Taxable income | Tax on the profit | Share of the profit |
|---|---|---|---|
| Held 364 days: flipped property, business income, 100% included | $240,000 | $66,027.54 | 44.02% |
| Held 365+ days, a capital gain on a property that was never a residence, 50% included | $165,000 | $29,908.83 | 19.94% |
| Held 365+ days, principal residence for every year owned | $90,000 | $0.00 | 0.00% |
Two gaps there deserve separate names. The $66,027.54 is the gap at its widest, the cost of selling one day early on a home that would otherwise have been exempt for every year owned, and it assumes the day-365 sale really is a capital gain. The $36,118.71 between the first two rows is what the deeming rule costs over and above losing the exemption, because it also takes away the 50% inclusion rate. That rate is the hinge the table turns on, and how capital gains are taxed in Canada sets out where it applies.
Every row runs off the same profit, and the profit is proceeds minus cost. For anyone who bought a place, worked on it and sold it, which spending is added to the cost of the property rather than written off decides how large that number gets, and capital improvements versus repairs draws the line.
Three pieces of the definition settle most cases
Subsection 12(13) defines flipped property as a property, other than one that would already be inventory, that is “(a) prior to its disposition by the taxpayer, either (i) a housing unit located in Canada, or (ii) a right to acquire a housing unit located in Canada; and (b) owned or, in the case of a right to acquire, held, by the taxpayer for less than 365 consecutive days prior to its disposition”, subject to the nine events below. Note the second limb of (a). A right to acquire is flipped property in its own right, so an assignment of a presale contract inside the window is caught without the condo ever being built.
Two details in that wording are easy to read past. It says less than 365 consecutive days, so exactly 365 days is outside the rule and the edge is a specific date rather than a rough twelve months. And it says due to, or in anticipation of one of the listed events, so the event need not have happened yet when you sell.
Outside the rule is not the same as safe. Where the deeming rule does not apply, CRA says, whether because of a life event or because the property was owned for at least 365 consecutive days, “it would remain a question of fact whether profits from the disposition are taxed as business income or a capital gain”. Below 365 days nobody asks what you intended when you bought. From day 365 that question is back.
The Department of Finance explanatory notes from August 2022 mark the outer edges: “Since the rule effectively recharacterizes capital gains as fully taxable ordinary income, it does not apply to dispositions that would otherwise result in ordinary income. The rule will also not apply to dispositions that would result in a loss.” A builder or renovator already reporting business income was never the target. The rule is aimed at the person who would otherwise have had a capital gain.
Nine life events take a sale out of the rule
CRA’s plain-language version, on its Principal residence and other real estate page, carries the tests the statute leaves to definitions elsewhere. It is the version to check a real sale against.
| The event | The test CRA states |
|---|---|
| Death | of the taxpayer or a related person |
| A household changes | a related person joining the taxpayer’s household or the taxpayer joining a related person’s household. CRA’s examples: moving in with a spouse or common-law partner, the birth of a child, adoption, care of an elderly parent |
| Relationship breakdown | living separate and apart from the spouse or common-law partner for at least 90 days before the disposition |
| A threat to personal safety | of the taxpayer or a related person. CRA’s example: domestic violence |
| Serious illness or disability | of the taxpayer or a related person |
| An eligible relocation | of the taxpayer or their spouse or common-law partner, where the new home is at least 40 kilometres closer to the new work location or school |
| Involuntary termination of employment | of the taxpayer or their spouse or common-law partner |
| Insolvency | of the taxpayer |
| Destruction or expropriation | CRA’s example: destroyed in a natural or man-made disaster |
One refinement sits in the statute rather than the summary. For the relocation test, subparagraph 12(13)(b)(vi) reads the “eligible relocation” definition without its requirement that the new work location and the new residence be in Canada. A move abroad for work can still qualify.
A pre-construction clock starts again on closing
This catches people who have done nothing wrong and waited a long time. CRA: “In the case of a taxpayer who owns a right to acquire a housing unit located in Canada, the 12-month holding period resets once the taxpayer who entered into a purchase and sale agreement secures ownership of the property.”
That follows from 12(13) treating the right and the unit as two different properties, each with its own 365-day clock. A buyer who signed a presale contract four years ago and closed last month has owned the housing unit for one month. The four years spent waiting for the building to go up earn no credit against the federal test.
British Columbia runs a second tax on a clock pointing the other way
The BC home flipping tax is imposed under the Residential Property (Short-Term Holding) Profit Tax Act and took effect January 1, 2025. The province is blunt that this is not a version of the federal rule: it “is separate and distinct from the federal property flipping rules and is not harmonized or administered with the federal or B.C. income tax”. It is charged on top of income tax, on its own return, due within 90 days of the sale, and the seller “may be a B.C. resident or a resident anywhere else in the world”.
The mechanics are in the Act itself. Section 8 charges the tax on a disposition less than 730 days after acquisition. Section 9(1)(a) sets 20% of net taxable income where the property was held for less than 366 days, and 9(1)(b) with 9(2) taper it past that at 20% x [1 - (days held - 365) / 365], rounded to the nearest one-thousandth, reaching nil past 729 days. Section 12(1) allows the primary residence deduction of up to $20,000, but only to a taxpayer who held the property for a minimum of 365 consecutive days and had a housing unit on it as their primary residence, so it is never available on a presale assignment.
BC has its own exemptions, and they do not line up with the federal ones. The federal rule accepts a sale made “due to, or in anticipation of” any of its nine events. BC splits its life circumstance exemptions in two. Death, serious illness or disability, an eligible relocation and a change in household membership can be anticipated. A relationship breakdown, an involuntary termination of employment, a threat to personal safety and insolvency have to have happened by the time you sell, and the termination exemption does not apply to self-employed individuals at all. So a BC seller moving ahead of a layoff they can see coming is in a different position provincially than federally. Separately, there are exemptions for builders and developers, for dispositions between related persons, for foreclosures, for property won in a lottery and for exempt locations including reserve and treaty lands. The province is also explicit that a life circumstance exemption still requires a return: “Even if you are claiming a life circumstance exemption, you must still file a return, otherwise penalties may be incurred.” The province’s exemptions pages set out each one.
British Columbia charges a second tax, on a two-year ramp. BC home flipping tax on the same $150,000 profit, for a home lived in as a primary residence. Source: Residential Property (Short-Term Holding) Profit Tax Act (British Columbia), sections 8, 9 and 12(1), for the 20% rate, the taper, the 730-day end point and the $20,000 deduction. Our arithmetic.
The $150,000 below is the same number used twice, not the same base: BC taxes proceeds less the cost of acquiring and the cost of improving the property (section 13(1)), and the federal computation is its own. On that profit, for a home lived in as a primary residence, BC takes $30,000 at 364 days, $26,000 at 365 days, $23,530 at 400 days, $16,380 at 500 days, $130 at 729 days and nothing at 730.
Set the first two of those against the federal cliff. BC charges the full 20% at exactly 365 days, while the federal rule has already let go at 365. A seller at exactly 365 days escapes the federal deeming, keeps access to the exemption, and still hands BC 20% on $130,000 after the deduction, which is $26,000.
For a presale buyer the two regimes can be close to inverted, because BC deems you to have acquired a presale property on the day you entered the contract. Its own worked example: “You enter into a presale contract on June 1, 2025, for a condo that will complete on March 1, 2027: If you acquire the condo when it is completed on March 1, 2027, you will be deemed to have acquired the property on June 1, 2025”.
Take those dates and sell on June 1, 2027. That is 730 days since signing, so the BC tax has run out. It is also 92 days since closing, well under 365, so the federal deeming rule applies in full: business income, no principal residence exemption. The day the provincial clock clears is a day deep inside the federal one.
What else changes when a gain becomes business income
A loss is deemed nil. Subsection 12(14) deems a taxpayer’s loss from a business in respect of a flipped property to be nil, and CRA says the same: “Any losses resulting from the sale of a flipped property is deemed to be nil.” Nor is there a capital loss to fall back on, for a reason that predates this rule: a home is personal-use property, and CRA’s position on any home is that a loss on the sale cannot be claimed. The rule runs one way.
Capital losses carried forward cannot be pointed at it. Section 111(1.1)(a)(i) caps the prior-year net capital loss deduction at the amount determined under paragraph 3(b), the year’s taxable capital gains net of allowable capital losses, while business income sits in paragraph 3(a). Anyone who has been harvesting losses in December for exactly this kind of moment should know the deduction does not reach here, and tax-loss selling in Canada covers what those losses can be used against.
CRA’s general split is Schedule 3 for a capital gain and Form T2125, Statement of Business or Professional Activities, for business income. A deemed business is a business, so the sale goes on the T2125. The whole profit lands in net income rather than half of it, and net income is the figure income-tested benefits and credits are measured against.
Instalments can follow the next year. CRA requires them where net tax owing is more than $3,000, or $1,800 for Quebec, in the current year and in either of the two preceding years, a threshold one flipped sale clears easily, and CRA tax instalments after a large one-off gain sets out when that obligation starts.
The date to put in the calendar
Count 365 consecutive days of ownership of the housing unit itself. Day 365 is not a safe day. It is the first day the deeming rule stops deciding the answer for you. What the wait is worth on our example is $66,027.54 at its widest, and $36,118.71 of that is what the deeming rule costs over and above losing the exemption. For a presale, count from closing, not from signing. For a property in British Columbia, run a second count from the day you signed, and remember it does not stop until day 730. If one of the nine events is in play, it need not have happened yet, but the sale has to be attributable to it or made in anticipation of it.
