The Myth: Spouses Inherit Tax-Free in Canada
Walk into any dinner party in Mississauga, Toronto, or Brampton and mention estate taxes. Someone will say: "Canada doesn't have an inheritance tax." They are technically correct — Canada does not levy a tax on the recipient of an inheritance. But that statement hides a mechanism that catches most families off guard: the deemed disposition at death.
When someone dies in Canada, the Income Tax Act treats them as having sold every capital asset — stocks, rental properties, investment accounts — at fair market value immediately before death. The capital gains generated on that "sale" are taxed on the deceased's final T1 return. This is not an inheritance tax in name, but the economic effect is similar: the estate pays tax on accumulated gains before the heirs receive anything. For a detailed walkthrough of how the deemed disposition works on a $500,000 RRSP with no surviving spouse, see our RRSP deemed disposition guide.
When assets pass to a surviving spouse or common-law partner, there is an exception — the spousal rollover under ITA s.70(6). But it does not eliminate the tax. It postpones it. And understanding that distinction is worth tens of thousands of dollars to your family.
How the Spousal Rollover Under ITA s.70(6) Actually Works
The spousal rollover is automatic. When capital property passes to a surviving spouse or common-law partner (either through a will or by operation of law), the assets transfer at the deceased's adjusted cost base (ACB) rather than at fair market value. No deemed disposition occurs. No capital gains are triggered on the deceased's final return for those specific assets.
Here is what that looks like on a $500,000 portfolio:
| Detail | Amount |
|---|---|
| Original purchase cost (ACB) | $200,000 |
| Fair market value at death | $500,000 |
| Unrealized capital gain | $300,000 |
| Tax triggered at death (with spousal rollover) | $0 |
| Cost base inherited by surviving spouse | $200,000 |
| Deferred capital gain carried by surviving spouse | $300,000 |
The surviving spouse receives a $500,000 portfolio — but with a $200,000 cost base attached to it. The $300,000 gain has not been taxed. It has not been forgiven. It has been deferred to the surviving spouse, who will owe capital gains tax when they sell the assets or when they die (whichever comes first). For a broader look at how capital gains work on inherited property, see our capital gains tax on inherited property guide.
Key distinction: The surviving spouse inherits the cost basis, not the value. This is the opposite of the U.S. "stepped-up basis" rule, where heirs receive assets at fair market value and prior gains are permanently eliminated. In Canada, no gain is ever eliminated through inheritance — it is only deferred until the next taxable event.
What Happens When the Surviving Spouse Sells: The Deferred Tax Calculation
Suppose the surviving spouse holds the inherited portfolio for five years, during which it grows from $500,000 to $600,000. They then sell the entire portfolio. Here is the capital gains calculation:
| Component | Amount |
|---|---|
| Sale proceeds | $600,000 |
| Inherited adjusted cost base | $200,000 |
| Total capital gain | $400,000 |
| First $250,000 at 50% inclusion | $125,000 taxable |
| Remaining $150,000 at 66.67% inclusion | $100,005 taxable |
| Total taxable capital gain | $225,005 |
At a combined federal-provincial marginal rate of approximately 48% to 53% (Ontario, income above $220,000), the tax bill on $225,005 of taxable income is roughly $108,000 to $119,000. That tax was deferred from the first spouse's death — not avoided. The surviving spouse is paying tax on gains that accumulated over the entire holding period, including the years before they inherited the assets.
When to Opt Out of the Spousal Rollover: ITA s.70(6.2)
The spousal rollover is automatic, but the executor can elect to opt out on a property-by-property basis under ITA s.70(6.2). This triggers the deemed disposition on the deceased's final return — generating capital gains tax — but also steps up the cost base for the surviving spouse.
Opting out makes financial sense in specific situations:
- The deceased has unused capital losses — carried-forward net capital losses can offset gains triggered by the deemed disposition. If the deceased has $80,000 in loss carryforwards, the executor can trigger up to $160,000 in capital gains (at 50% inclusion) with zero net tax, while stepping up the spouse's cost base by $160,000.
- The deceased has very low income in their final year — if the deceased died early in the year with minimal income, the basic personal amount ($16,129 in 2026) and graduated tax rates mean the first $55,000 to $60,000 of taxable income (including capital gains) is taxed at relatively low federal rates (15% to 20.5%).
- The portfolio has a mix of high-gain and low-gain assets — the executor can selectively opt out on low-gain assets (small tax cost, meaningful cost base step-up) while rolling over high-gain assets.
Planning opportunity: A well-advised executor reviews the deceased's loss carryforwards, final-year income, and the cost base of each asset before deciding whether to accept the automatic rollover or opt out selectively. This analysis can save the surviving spouse $20,000 to $50,000 in future capital gains tax — but it must be done before filing the final T1 return. Most families miss this because the automatic rollover feels like the "right" choice.
RRSP and RRIF Assets: A Different Kind of Rollover
Registered accounts follow their own rollover rules. When the deceased names their spouse as the beneficiary (or successor annuitant) of an RRSP or RRIF, the full account value transfers to the surviving spouse's own RRSP or RRIF without triggering income inclusion on the deceased's final return.
Without a surviving spouse beneficiary, the entire RRSP or RRIF balance is included as income on the deceased's final return — potentially pushing the final return into the highest tax bracket. On a $500,000 RRSP, this could generate $200,000 or more in combined federal-provincial tax. The spousal rollover for registered accounts is therefore even more valuable than for non-registered capital property. For the full tax impact when there is no surviving spouse, see our detailed RRSP deemed disposition walkthrough.
Quebec Civil Law vs. Common-Law Provinces: Community of Property Differences
The spousal rollover under the federal Income Tax Act applies across all provinces. But the underlying property ownership rules differ significantly between Quebec and the rest of Canada, which affects what actually qualifies for the rollover.
Common-Law Provinces (Ontario, BC, Alberta, etc.)
In common-law provinces, each spouse owns their property individually during the marriage. At death, the deceased's assets pass through their estate (governed by the will or intestacy rules). The spousal rollover applies straightforwardly: assets owned by the deceased transfer to the surviving spouse at the original cost base.
Quebec: Family Patrimony and Partnership of Acquests
Quebec operates under civil law with two layers of property sharing:
- Family patrimony (patrimoine familial) — the family residence, household furnishings, registered retirement savings (RRSPs, RRIFs), and motor vehicles are automatically shared equally between married spouses, regardless of title. At death, the surviving spouse is entitled to half the net value of the family patrimony before the estate is settled.
- Partnership of acquests (société d'acquêts) — the default matrimonial regime in Quebec. Assets acquired during the marriage (other than gifts and inheritances) are shared equally at dissolution. This is a separate calculation from the family patrimony.
The practical effect is that in Quebec, the surviving spouse may already own half of certain assets as a matter of matrimonial law — not inheritance. The spousal rollover under the ITA still applies to the portion that transfers through the estate, but the patrimony division happens first. This can create complex interactions between Quebec civil law and federal tax law that require specialized planning. For more on Quebec-specific inheritance rules, see our Quebec common-law spouse estate guide.
Quebec common-law partners: De facto spouses (conjoints de fait) in Quebec have no automatic inheritance rights under Quebec succession law, and the family patrimony rules do not apply to them. A common-law partner in Quebec must be specifically named in the will to inherit — and even then, the spousal rollover under the federal ITA applies only if they meet the CRA definition of common-law partner (living together in a conjugal relationship for at least 12 continuous months).
Executor's CRA Filing Timeline: A Worked Example
Understanding the filing deadlines is critical for executors. Missing a deadline can result in penalties, interest, and personal liability. Here is a timeline based on a death occurring on March 15, 2026, with a surviving spouse inheriting a $500,000 portfolio:
| Deadline | Filing Requirement | Notes |
|---|---|---|
| Sept 15, 2026 | Deceased's final T1 return | 6 months after death (later than April 30, 2027 rule since death was in 2026). Spousal rollover election or opt-out decided here. |
| Sept 15, 2026 | Tax balance owing on final return | Same deadline as the return. Interest accrues from this date on any unpaid balance. |
| 90 days after estate year-end | T3 Trust return for the estate | Required if the estate earns income or distributes capital property. Estate can choose a fiscal year-end up to 12 months from date of death. |
| Before distributing assets | Request clearance certificate (TX19) | CRA processing takes 3 to 6 months. Without it, executor is personally liable for unpaid taxes. |
| Within 36 months of death | Graduated rate estate (GRE) designation ends | After 36 months, the estate loses access to graduated personal tax rates and is taxed at the top marginal rate. |
The clearance certificate step is where most executors encounter delays. CRA will not issue the certificate until all returns are filed and assessed, including the T3. Distributing estate assets before receiving the clearance certificate exposes the executor to personal liability if CRA later determines additional tax is owed.

The Real Cost of Deferral: A Complete $500,000 Timeline
To put the entire mechanism in perspective, here is a simplified timeline showing how the spousal rollover plays out over a typical scenario:
- 2010: Couple purchases a diversified portfolio for $200,000 in a non-registered account.
- 2026: First spouse dies. Portfolio is worth $500,000. Spousal rollover applies automatically — no tax at death. Surviving spouse inherits the $200,000 cost base.
- 2031: Surviving spouse needs funds for long-term care. Sells $250,000 of the portfolio. Capital gain: $250,000 minus $100,000 (proportional ACB) = $150,000. Tax at approximately 25% effective rate on the taxable portion: roughly $20,000 to $28,000.
- 2035: Surviving spouse dies. Remaining portfolio worth $350,000 with a $100,000 cost base. Deemed disposition triggers $250,000 capital gain on final return. Tax on surviving spouse's final return: approximately $45,000 to $65,000 depending on other income.
Total tax paid across both events: $65,000 to $93,000. This is the tax that was "deferred" by the spousal rollover — not eliminated. Had the first spouse's estate paid at death in 2026, the tax would have been approximately $50,000 to $60,000 on the $300,000 gain, but the surviving spouse would have inherited a stepped-up $500,000 cost base and owed significantly less on subsequent sales and at their own death.

Key Takeaways
- 1Canada has no inheritance tax, but the deemed disposition at death triggers capital gains tax on the deceased's final return — the spousal rollover under ITA s.70(6) defers this tax, it does not eliminate it
- 2Your surviving spouse inherits the original adjusted cost base, not the fair market value — on a $500,000 portfolio purchased for $200,000, the spouse inherits a $200,000 cost base and a $300,000 deferred capital gain
- 3Executors can opt out of the spousal rollover on specific assets when the deceased has unused capital losses or low final-year income — this can step up the cost base and reduce the surviving spouse's future tax bill
- 4At the 2026 capital gains inclusion rate (two-thirds above $250,000), a $300,000 deferred gain could generate $116,667 to $150,000 in taxable income on the surviving spouse's final return
- 5Quebec civil law adds a layer: the family patrimony rules divide certain assets before inheritance, meaning the spousal rollover interacts differently than in common-law provinces
- 6The executor's final T1 return is due the later of six months after death or April 30 of the following year — request a clearance certificate (TX19) before distributing assets to avoid personal liability

Frequently Asked Questions
Q:Does Canada have an inheritance tax when a spouse inherits assets?
A:Canada does not have a formal inheritance tax or estate tax. However, when someone dies, the Income Tax Act treats them as having sold all their capital property at fair market value immediately before death — this is the deemed disposition rule under ITA s.70(5). The resulting capital gains are taxed on the deceased's final tax return. When assets pass to a surviving spouse or common-law partner, ITA s.70(6) provides an automatic rollover: the assets transfer at their original adjusted cost base instead of fair market value, deferring the capital gains tax until the surviving spouse eventually sells or dies. The tax is not eliminated — it is postponed. The surviving spouse inherits the original cost basis and will owe capital gains tax on the full accumulated gain when the assets are eventually disposed of.
Q:What is the spousal rollover under ITA s.70(6) and how does it work?
A:The spousal rollover under section 70(6) of the Income Tax Act is an automatic provision that applies when capital property passes from a deceased person to their surviving spouse or common-law partner. Instead of triggering a deemed disposition at fair market value (which would generate capital gains tax on the deceased's final return), the assets transfer at their adjusted cost base (ACB). For example, if the deceased purchased shares for $200,000 and they are worth $500,000 at death, the spousal rollover transfers the shares to the surviving spouse at the $200,000 cost base — no capital gains tax is triggered at death. The rollover applies automatically unless the executor elects to opt out on the deceased's final T1 return. It covers all capital property transferring to the spouse, including stocks, real estate (other than the principal residence), and RRSP/RRIF assets.
Q:When should an executor opt out of the spousal rollover in Canada?
A:An executor may elect to opt out of the spousal rollover under ITA s.70(6.2) when the deceased has unused capital losses, low income in their final year, or other deductions that would offset the capital gains triggered by a deemed disposition at fair market value. For example, if the deceased has $80,000 in carried-forward capital losses and a $500,000 portfolio with $300,000 in unrealized gains, the executor could opt out on specific assets to trigger up to $160,000 in capital gains (offset by the $80,000 in losses, resulting in zero net tax) while stepping up the cost base for the surviving spouse. This reduces the deferred tax bill the surviving spouse will eventually face. Opting out is done on a property-by-property basis — the executor does not have to opt out on all assets. The election must be made on the deceased's final T1 return, filed within the normal deadline or the extended six-month period for year-of-death returns.
Q:What happens to deferred capital gains when the surviving spouse dies in Canada?
A:When the surviving spouse dies, the deemed disposition rule under ITA s.70(5) applies in full — there is no second spousal rollover unless the surviving spouse has also remarried or has a new common-law partner to whom assets can roll over. All capital property is deemed sold at fair market value immediately before death. The capital gains are calculated based on the original cost base inherited from the first spouse, not the value at the time of the first spouse's death. In the case of a $500,000 portfolio originally purchased for $200,000, if the portfolio has grown to $600,000 by the time the surviving spouse dies, the taxable capital gain is $400,000 (the full gain from the original $200,000 cost base). At the 2026 capital gains inclusion rate, two-thirds of gains above $250,000 are included in income, resulting in a significant tax bill on the surviving spouse's final return.
Q:How does Quebec civil law affect spousal inheritance differently from common-law provinces?
A:Quebec operates under a civil law system with community of property (patrimoine familial) rules that differ significantly from common-law provinces. In Quebec, married spouses automatically share the family patrimony — which includes the family residence, household furnishings, registered retirement savings, and motor vehicles — regardless of whose name is on the title. At death, the surviving spouse is entitled to half the value of the family patrimony before the estate is settled. This means the spousal rollover interacts differently in Quebec: assets within the family patrimony may already be partially owned by the surviving spouse as a matter of law, not just inheritance. Common-law partners in Quebec (called de facto spouses) have no automatic inheritance rights and are not recognized under Quebec succession law unless named in a will. The spousal rollover under the federal Income Tax Act still applies to Quebec married spouses, but the underlying property division follows Quebec civil law rather than provincial family law statutes in other provinces.
Q:What are the CRA filing deadlines for an executor after a death in Canada?
A:The executor (called a liquidator in Quebec) must file the deceased's final T1 income tax return by the later of: six months after the date of death, or April 30 of the year following the year of death. For example, if the deceased died on March 15, 2026, the final return is due by September 15, 2026. If the deceased died on October 1, 2026, the final return is due by April 1, 2027 (six months after death, which is later than April 30, 2027 — actually in this case April 30 is later, so April 30, 2027 applies). The executor must also file a T3 Trust return for the estate if the estate earns income or distributes capital property — the first T3 is due 90 days after the estate's fiscal year-end. Additionally, a clearance certificate (form TX19) should be requested from CRA before distributing estate assets to confirm all taxes are paid. Without the clearance certificate, the executor is personally liable for any unpaid tax. The clearance certificate request can take 3 to 6 months for CRA to process.
