Deemed Disposition in Canada: When You Are Taxed Without Selling
Most capital gains tax bills start with a sale. Some do not. Canadian tax law contains a set of rules that treat you as having sold something at its market value when you never received a cent — when you leave the country, when you turn your home into a rental, when you gift an asset. These are deemed dispositions, and the tax is just as real as if you had cashed out.
A deemed disposition is when the Canada Revenue Agency treats you as having sold a property at its fair market value and immediately reacquired it at that same value, without an actual sale. It triggers a capital gain or loss you must report. The common triggers are emigrating from Canada (departure tax), changing a property’s use between personal and rental or business, gifting capital property, selling to someone you are not at arm’s length with below market value, and death.
| Trigger | What happens | Key form or relief |
|---|---|---|
| You emigrate from Canada | Deemed sale at FMV of most property (departure tax) | Form T1243; T1161 if property over $25,000; tax may be deferred by election |
| Home becomes a rental (or vice versa) | Deemed sale at FMV on the date the use changes | Elections under ITA 45(2) or 45(3) may defer it |
| You gift capital property | Deemed sale at FMV at the time of the gift | Report the gain on Schedule 3 |
| Sale below FMV to a non-arm’s-length person | Proceeds deemed to be FMV anyway | None — pricing it low does not help |
| Death | Deemed sale at FMV immediately before death | Spousal rollover may defer it |
| Registered accounts (RRSP, TFSA, RRIF) | Generally NOT deemed disposed on emigration | Excluded rights or interests |

What a deemed disposition actually means
The mechanic is always the same in Canada, whatever the trigger. You are treated as having sold the property at its fair market value on a particular date, and as having immediately bought it back for that same amount. Two consequences follow, and the second is the one people forget.
- You report a gain or loss now. The difference between that deemed value and your adjusted cost base is a capital gain or loss in the year of the event, with the usual 50% inclusion rate.
- Your cost base resets upward. Because you are deemed to have reacquired at that same value, the gain you just paid tax on is never taxed again. Only growth after that date is taxable when you eventually sell for real.
That reset is why a deemed disposition is a timing event rather than a permanent penalty. The problem is cash: the tax is due on your return for that year, but no money changed hands to pay it with.
Departure tax: leaving Canada
When you cease to be a resident of Canada, the CRA deems you to have disposed of most of your property at fair market value on your departure date and to have immediately reacquired it at that value. This is commonly called departure tax, and it applies to shares, jewellery, paintings, collections, and most other capital property.
Several categories are excluded from the deemed disposition. The main ones are:
- Canadian real or immovable property, Canadian resource property, and timber resource property
- Canadian business property, including inventory, if the business is carried on through a permanent establishment in Canada
- Registered plans — RRSPs, RRIFs, TFSAs, RESPs, RDSPs, PRPPs, pensions, annuities, DPSPs and other “excluded rights or interests”
- Property you owned when you last became a Canadian resident, or inherited afterward, if you were resident for 60 months or less in the 10 years before emigrating
Two filing points matter more than most people realize. You report the deemed disposition on Form T1243 and carry the result to Schedule 3. Separately, if the total fair market value of the property you owned when you left exceeded $25,000, you must file Form T1161 listing your properties inside and outside Canada. The penalty for filing T1161 late is $25 per day, with a minimum of $100 and a maximum of $2,500, and the CRA requires it even if you would otherwise not need to file a return at all.
Canada lets you elect to defer paying the tax on a departure-tax gain, regardless of the amount, and pay it later without interest when you actually dispose of the property. This is the relief valve for the cash-flow problem — being deemed to have sold a large portfolio does not have to mean liquidating part of it to pay the CRA. Security may be required for larger amounts, so this is a conversation to have with a cross-border tax adviser before you leave, not after.
Change of use: your home becomes a rental
The CRA is explicit: every time you change the use of a property in Canada, you are considered to have sold it at fair market value and to have immediately reacquired it for the same amount. The two everyday versions are turning all or part of a principal residence into a rental or business property, and turning a rental or business property into a principal residence.
This surprises people who move out and rent their old home rather than selling it. Nothing was sold, no money arrived, but a capital gain can be triggered on the date the tenants move in.
The relief is that the principal residence exemption still shelters the years the place actually was your principal residence. Only the years it was not designated are taxable, which our guide to capital gains tax on selling property in Canada works through in detail.
There are also elections under subsections 45(2) and 45(3) of the Income Tax Act that let you treat the change of use as not having happened, deferring the gain. They come with conditions — a 45(2) election is generally rescinded if you claim capital cost allowance on the property, for instance — so this is a case where the election is worth making correctly with professional help rather than approximately on your own.
Gifts and sales to family below market value
Giving away capital property in Canada is a disposition. If you gift an asset, you are considered to have sold it at its fair market value at the time of the gift, and you report any resulting capital gain or loss — the person receiving it pays nothing, but you may owe tax on a sale you did not make.
Selling cheaply to a relative does not avoid this either, and can make it worse. When you sell to someone you do not deal with at arm’s length for less than fair market value, your proceeds are deemed to be the fair market value anyway. The buyer’s cost base, meanwhile, is the price they actually paid. The result is double taxation on the same increase in value: you are taxed on a gain you did not receive, and they will later be taxed again on it.
The mirror rule applies on the way in: if you buy from a non-arm’s-length person for more than fair market value, your cost is deemed to be the fair market value.

Death, briefly
Death is the deemed disposition most Canadians have heard of: a person is treated as having disposed of their capital property at fair market value immediately before death, and the resulting gain is reported on their final return. A transfer to a surviving spouse or common-law partner can roll the property over at cost instead, deferring the tax. Because the estate and inheritance side of this has its own rules, we cover it separately in our guide to capital gains tax on inherited property in Canada.
One further trigger worth naming, though it is beyond most personal situations: property held in a family trust faces a deemed disposition every 21 years, which is why trust planning tends to involve advisers well before that date arrives.
What to do when a deemed disposition is coming
Unlike a real sale, a deemed disposition in Canada is usually foreseeable — you know you are emigrating, renting out the house, or transferring an asset. Three things are worth doing before the date rather than after:
- Establish the fair market value with evidence. An appraisal for real estate, or documented closing prices for securities, on the exact date. The valuation is the whole tax calculation, and reconstructing it later invites dispute.
- Know your adjusted cost base first. The gain is only as accurate as your cost base, and averaging rules for identical shares trip up more filings than the deemed-disposition rules themselves.
- Consider whether a loss elsewhere can absorb it. A deemed gain is still a capital gain, so unused net capital losses apply against it — see capital loss carryforward for how the three-year carryback and indefinite carryforward work.

Frequently asked questions
A deemed disposition is when the CRA treats you as having sold a property at its fair market value, and immediately reacquired it at that value, without an actual sale taking place. You report the resulting capital gain or loss for that year, and your cost base resets to the deemed value.
When you cease to be a Canadian resident, you are deemed to have disposed of most of your property at fair market value on your departure date, and the resulting capital gain is taxable. It is reported on Form T1243. Canadian real property and registered plans such as RRSPs and TFSAs are among the exceptions.
Potentially. Changing the use of a property is a deemed disposition at fair market value on the date of the change, so a capital gain can arise even though nothing was sold. The years the property genuinely was your principal residence remain sheltered, and elections under subsections 45(2) and 45(3) may defer the gain.
For the giver, generally yes. You are considered to have sold the property at fair market value at the time of the gift and must report any capital gain. The person receiving the gift does not pay tax on receiving it, and their cost base is that same fair market value.
No. In a non-arm’s-length sale below fair market value, your proceeds are deemed to be fair market value, so you are taxed as if you sold at full price. Your child’s cost base is only the amount actually paid, so the same gain gets taxed a second time when they sell.
Not necessarily. You can elect to defer payment of the tax on a departure-tax gain, regardless of the amount, and pay it without interest when you actually dispose of the property. Security may be required for larger amounts.

This article is general information, not tax advice. Deemed disposition rules interact with residency status, treaties, elections, and property type in ways that depend on your circumstances. Emigration, change-of-use elections, and non-arm’s-length transfers in particular should be planned with a qualified tax professional before the event, not after. Confirm current rules with the Canada Revenue Agency.
