An $850,000 Capital Gain on a Family Home — and Zero Tax Owed (If You Do It Right)
A Toronto couple bought their home in 2001 for $350,000. By 2026, it is worth $1.2 million. When the homeowner dies, CRA triggers a deemed disposition at fair market value — the same treatment as if the home were sold the moment before death. The capital gain: $850,000.
Under the 2026 capital gains inclusion rate, the first $250,000 of capital gains is included at 50%, and gains above $250,000 are included at 66.7%. On an $850,000 gain, that produces roughly $525,000 of taxable income added to the deceased's final return. At Ontario's top marginal rate of 53.53%, the tax bill would exceed $280,000.
The principal residence exemption exists precisely to prevent this. When the home qualifies as the deceased's principal residence for every year of ownership, the PRE eliminates the entire gain — $0 in capital gains tax. But three common scenarios cause partial or total loss of the exemption, and a single missed form can make the full gain taxable. For a broader overview of how deemed dispositions work on death, see our complete guide to deemed dispositions at death in Canada.
How the Principal Residence Exemption Works on Death
When a Canadian dies, all capital property is deemed disposed of at fair market value immediately before death. For the family home, this creates a capital gain equal to the difference between FMV at death and the original adjusted cost base (purchase price plus eligible improvements).
The principal residence exemption shelters this gain using CRA's formula:
PRE Formula
Exempt portion = (1 + number of years designated as principal residence) ÷ (number of years owned) × capital gain
The "+1" in the numerator is a bonus year that covers a change-of-residence year — it means you get one free year of coverage even when transitioning between properties.
If the deceased owned the home for 25 years (2001–2026) and it was their principal residence for all 25 years, the formula produces: (1 + 25) / 25 = 26/25 = 1.04 — capped at 1.0, meaning 100% of the gain is exempt. The entire $850,000 gain disappears from the final return.
But this only works if two conditions are met: the home genuinely qualifies as a principal residence for every designated year, and the executor files Form T1255 with the final tax return.
Scenario 1: Multi-Property Families — The Cottage Problem
The most common reason Ontario families lose part of the principal residence exemption is owning a second property. Only one property per year can be designated as a principal residence per family unit. If the deceased owned both a Toronto home and a Muskoka cottage, the executor must decide which property gets the designation for each year of ownership.
The optimal strategy is to designate the property with the larger per-year gain for each year. Consider this example:
| Property | Purchase Price | FMV at Death | Capital Gain | Years Owned | Gain per Year |
|---|---|---|---|---|---|
| Toronto home | $350,000 | $1,200,000 | $850,000 | 25 | $34,000 |
| Muskoka cottage | $200,000 | $650,000 | $450,000 | 20 | $22,500 |
The Toronto home has a higher per-year gain ($34,000 vs. $22,500), so the executor should designate it as the principal residence for all 25 years. The cottage's $450,000 gain is then fully taxable. Under the 2026 inclusion rates, the taxable income on the cottage gain alone could produce a tax bill of approximately $120,000–$130,000.
The alternative — designating the cottage for some years and the home for others — requires careful year-by-year allocation. Getting this wrong can mean paying tax on both properties when one could have been fully sheltered. For families with inherited cottages, this intersects directly with the issues covered in our guide to capital gains tax on inherited property.
Scenario 2: Years the Home Was Rented Out
If the deceased rented out the family home for a period — whether because they moved in with a partner, took a work assignment in another city, or simply wanted rental income — those years may not qualify for the principal residence designation. A home must be "ordinarily inhabited" by the owner, their spouse, or their child to qualify as a principal residence for a given year.
Consider a homeowner who purchased in 2001 for $350,000, rented the home from 2010 to 2014 while living elsewhere, then moved back in until death in 2026. They owned the home for 25 years but can only designate 20 years (plus the +1 bonus year) as principal residence years.
PRE calculation with rental years: Exempt portion = (1 + 20) / 25 = 21/25 = 84%. On an $850,000 capital gain, 84% is exempt ($714,000) and 16% is taxable ($136,000). With the 2026 capital gains inclusion rates, the taxable portion produces roughly $90,000 of taxable income — and a tax bill of approximately $40,000–$48,000 depending on other income in the year of death.
There is a partial relief provision. Under subsection 45(2) of the Income Tax Act, a taxpayer who begins renting out their home can elect to continue treating it as their principal residence for up to four additional years, provided they do not claim capital cost allowance (CCA) on the property and they file the election in the year the change of use occurs. But this election must have been made while the owner was alive — the executor cannot make it retroactively after death.
If the deceased claimed CCA on the rental property at any point, the 45(2) election is unavailable for those years and the rental period fully reduces the PRE.
Scenario 3: Bare Land and Properties That Don't Qualify
The principal residence exemption requires a "housing unit" — a house, apartment, condo, cottage, mobile home, or trailer. Bare land does not qualify unless it is the land on which a housing unit sits (up to half a hectare, or more if the excess is necessary for the use and enjoyment of the home). Vacant lots held for future development, farmland without a residence, or properties where the house was demolished before death do not qualify for the PRE.
In the GTA, this most commonly arises when a homeowner's property is rezoned for development. If the house was demolished and the land was being held as a development asset, the PRE is lost — and the full capital gain on a valuable Toronto lot can be substantial.
The T1255 Filing: The Form That Protects a Six-Figure Exemption
Form T1255 — Designation of a Property as a Principal Residence by the Legal Representative of a Deceased Individual — is the mechanism by which the executor claims the PRE on the final tax return. Without it, CRA does not apply the exemption.
The T1255 must be filed with the deceased's terminal T1 return (due by April 30 of the year following death, or six months after the date of death — whichever is later). The form requires:
- Description of the property and its address
- Date of acquisition and proceeds of disposition (FMV at death)
- The years for which the property is being designated as the principal residence
- Whether the deceased owned any other property that could qualify as a principal residence
The cost of missing the T1255: If the executor files the terminal return without the T1255, CRA assesses the full capital gain as taxable. On an $850,000 gain, this can mean a tax bill of $150,000–$280,000 depending on inclusion rate thresholds and other income. CRA may accept a late-filed T1255, but at a penalty of $100 per month late (to a maximum of $8,000) and only at CRA's discretion. There is no guaranteed right to late-file. The T1255 should be the first form the estate's accountant prepares.
Ontario Probate Fees: A Separate Bill on the Same Home
Even when the PRE eliminates all capital gains tax, the family home is still subject to Ontario's Estate Administration Tax (probate fees) if it passes through the estate. Ontario charges:
- $5 per $1,000 on the first $50,000 of estate value
- $15 per $1,000 on estate value above $50,000
For a $1.2 million home (assuming it is the only estate asset for simplicity):
| Calculation | Amount |
|---|---|
| First $50,000 × $5/1,000 | $250 |
| Remaining $1,150,000 × $15/1,000 | $17,250 |
| Total Ontario probate fees on the home | $17,500 |
Probate fees are calculated on the fair market value of the property, not the capital gain — so the PRE does nothing to reduce this cost. Some families use joint tenancy with right of survivorship to pass the home outside the estate and avoid probate fees entirely. However, adding a child as joint tenant creates its own tax risks (deemed disposition of a partial interest, loss of full PRE coverage, and potential creditor exposure). For a deeper look at probate avoidance strategies, see our guide to avoiding probate in Ontario.
Passing the Home to Children vs. a Surviving Spouse: The $150,000 Difference
The tax treatment of the family home on death depends entirely on who inherits it.
Scenario A: Home Passes to Adult Children (No Surviving Spouse)
| Item | Without PRE | With PRE (T1255 filed) |
|---|---|---|
| Capital gain on $1.2M home | $850,000 | $850,000 |
| PRE exemption | $0 | $850,000 |
| Taxable capital gain | ~$525,000 | $0 |
| Estimated federal + Ontario tax | ~$280,000 | $0 |
| Ontario probate fees | $17,500 | $17,500 |
| Total estate cost | ~$297,500 | $17,500 |
The difference between filing and not filing the T1255: $280,000. This is the single most valuable form in Canadian estate administration for homeowners. For a complete walkthrough of what adult children face when inheriting a large estate, see our guide to inheriting a $1M Ontario estate.
Scenario B: Home Passes to a Surviving Spouse
When the home passes to a surviving spouse (married or common-law), the spousal rollover under subsection 70(6) applies automatically. There is no deemed disposition at fair market value — the property transfers to the surviving spouse at the deceased's adjusted cost base. No capital gain is triggered, no PRE is needed, and no T1255 is required.
| Item | Spousal Rollover |
|---|---|
| Deemed disposition at FMV | No — rolls at ACB |
| Capital gains tax on first death | $0 |
| Ontario probate fees (if through estate) | $17,500 |
| Probate fees (if joint tenancy) | $0 |
| Total tax cost on first death | $0–$17,500 |
The deferred tax trap: The spousal rollover does not eliminate the gain — it defers it. When the surviving spouse eventually dies (or sells the home), the full accumulated gain from the original purchase price is triggered. If the home has appreciated further, the gain on the surviving spouse's final return could be even larger. The PRE must then be claimed on the surviving spouse's terminal return — meaning the T1255 requirement simply shifts to the second death. For the full mechanics of spousal rollovers, see our guide to spousal rollovers in Canada.
The Properly Structured Will: What It Must Include for the PRE
A will that simply says "I leave my home to my children" does not address the PRE filing. The executor may not know about the T1255, may not know how to allocate designation years in a multi-property situation, or may not realize the stakes of getting it wrong.
A properly drafted will for a homeowner should include:
Estate Planning Checklist for Principal Residence Protection
- Explicit executor instructions to file Form T1255 — do not assume the estate accountant will know to do this. Specify which property should be designated and for which years.
- Multi-property allocation analysis — if you own more than one property that could qualify, have an accountant prepare a year-by-year gain allocation before death so the executor has a clear roadmap.
- Documentation of rental history — if the home was ever rented out, record the dates, whether CCA was claimed, and whether a 45(2) election was filed. This information may not be easily recoverable after death.
- Spousal rollover vs. PRE decision — if there is a surviving spouse, decide whether the home should pass via spousal rollover (deferring the gain) or directly to children (using the PRE now). This depends on the surviving spouse's age, health, and whether they plan to sell the home.
- Joint tenancy review — determine whether joint tenancy with right of survivorship (for probate avoidance) is appropriate or whether the home should pass through the estate for better tax planning control.
What Most Executors Get Wrong
Estate lawyers and accountants who handle estates regularly know about the T1255. But in many Ontario families, the executor is an adult child or sibling with no estate administration experience. The three most common PRE-related mistakes:
- Not filing the T1255 at all — the executor assumes the PRE is automatic, or does not know the form exists. CRA assesses the full capital gain, and the estate receives a tax bill that could have been $0.
- Wrong year allocation in multi-property situations — the executor designates the wrong property for too many years, leaving the higher-gain property partially exposed. This often happens when the executor does not have access to historical cost base records.
- Not knowing about rental periods or CCA claims — the executor files the T1255 claiming the home as principal residence for years it was rented out. CRA can reassess the return, deny the exemption for those years, and add interest and penalties to the resulting tax bill.
All three mistakes are preventable with proper documentation during the homeowner's lifetime.
The Bottom Line: A $1.2M Toronto Home and the PRE
For a single-property Ontario homeowner who lived in their Toronto home continuously from purchase to death, the principal residence exemption eliminates the entire capital gain. The T1255 is a straightforward filing, and the tax saving is enormous — potentially $280,000 on an $850,000 gain.
The complexity — and the risk — arises in three situations: multiple properties that compete for designation years, rental periods that reduce the available years, and executor error in filing the T1255. Each of these can turn a tax-free transfer into a six-figure tax bill.
Ontario probate fees add approximately $17,500 on a $1.2M home regardless of the PRE — a separate cost that requires its own planning strategy (joint tenancy, spousal transfer, or trust structures). For the complete picture of Ontario probate planning, see our Ontario probate fee calculator.

Key Takeaways
- 1On death, CRA deems the family home sold at fair market value — a $1.2M Toronto home purchased for $350,000 triggers an $850,000 capital gain unless the principal residence exemption eliminates it
- 2The PRE is not automatic at death: the executor must file Form T1255 with the final tax return, and a missed filing can result in the full gain being taxed at the 2026 capital gains inclusion rate
- 3Multi-property families (home plus cottage) can only designate one property per year — the other property's gain is fully taxable, and the wrong allocation can cost tens of thousands of dollars
- 4Years the home was rented out reduce the PRE proportionally — five years of rental on a 25-year ownership means 20% of the capital gain is taxable even with the exemption
- 5Ontario probate fees apply to the full $1.2M home value regardless of the PRE — approximately $17,500 in Estate Administration Tax that is separate from any capital gains tax
- 6A surviving spouse receives the home via tax-free spousal rollover with no deemed disposition, but when the surviving spouse later dies, the full accumulated gain is taxed on their final return

Frequently Asked Questions
Q:Does the principal residence exemption apply automatically on death in Canada?
A:No. The executor must file Form T1255 (Designation of a Property as a Principal Residence by the Legal Representative of a Deceased Individual) with the deceased's final tax return. If the T1255 is not filed, CRA does not apply the exemption — the full capital gain on the deemed disposition is taxable. CRA may accept a late T1255 filing with a penalty, but there is no guarantee. The executor should treat the T1255 as a mandatory filing for any estate that includes a home the deceased lived in.
Q:How is the principal residence exemption calculated on death?
A:CRA uses the formula: exempt portion = (1 + number of years designated) / (number of years owned) × capital gain. The '+1' in the formula covers one change-of-residence year. If the deceased owned and lived in the home for the entire period of ownership, the exemption covers 100% of the gain and no tax is owed. If the home was not the principal residence for some years (e.g., it was rented out or a second property was designated), the exemption is prorated and only a portion of the gain is sheltered.
Q:What happens to the principal residence exemption if the deceased also owned a cottage?
A:Only one property per year can be designated as a principal residence per family unit. If the deceased owned both a Toronto home and a cottage, the executor must choose which property to designate for each year of ownership. Typically, you designate the property with the larger per-year gain to maximize the exemption. The other property's gain for those years is fully taxable. This is the most common reason families lose part of the PRE on a home — the cottage consumes designation years that cannot also be used for the city home.
Q:Is the family home included in Ontario probate fee calculations?
A:Yes. Ontario's Estate Administration Tax (probate fees) applies to the total fair market value of all assets that pass through the estate, including the family home — regardless of whether the principal residence exemption eliminates the capital gains tax. For a $1.2M home, the probate fee alone is approximately $17,500. Probate fees and capital gains tax are separate obligations: the PRE eliminates the capital gain, but does nothing to reduce probate fees. Joint tenancy with right of survivorship can bypass probate, but has its own risks.
Q:Can the principal residence exemption be claimed if the home was rented out for some years?
A:Yes, but only for the years the property actually qualified as the owner's principal residence. If a Toronto home was rented from 2015 to 2019 and the owner lived elsewhere during those years, those five years cannot be designated as principal residence years. The exemption formula prorates the sheltered gain accordingly. There is a partial relief rule (the '4-year election' under subsection 45(2)) that allows continued designation for up to four years of rental if the owner did not claim CCA and elected in time — but this must have been elected while the owner was alive, not retroactively by the executor.
Q:What happens if the executor misses the T1255 filing deadline?
A:If the executor does not file Form T1255 with the deceased's final return, CRA treats the entire capital gain as taxable. CRA does have discretion to accept late-filed designations, but the executor may face a penalty of $100 per month late (up to $8,000 maximum) under subsection 220(3.2). There is no automatic right to a late filing — the executor must request it and CRA must agree. Given that the tax at stake on a $1.2M home can exceed $150,000, the T1255 should be treated as one of the most important documents in the estate administration process.
