OAS at Death — What Happens to Old Age Security in Canada

A 79-year-old widow in Halifax dies on the 4th of the month. Her son, named as executor, spends the next six weeks dealing with the funeral and the will and does not get around to calling Service Canada until early in the second month after the death. By then, two OAS payments and two GIS payments have landed in his mother's chequing account — close to $2,200 in total — and Service Canada politely asks for the second month's amount back. The first month is hers; the second month is not.

This is the most common surprise around Old Age Security at death. OAS is not a household pension and there is no widow's or widower's continuation. The payment for the month of death belongs to the deceased's estate; everything after it has to be returned. The executor's job is largely the administrative one of notifying Service Canada and handling the partial-month accounting.

This guide walks the end-of-life OAS rules, the related Guaranteed Income Supplement (GIS) treatment, the Allowance for the Survivor that some widowed Canadians qualify for, and the CPP-side rules that often get blurred together with OAS.

OAS is individual, not household #

The Old Age Security Act, RSC 1985, c O-9, structures OAS as a personal pension paid based on age, residence in Canada, and (for higher-income recipients) net income — not on household status.^[1] When the recipient dies, the pension ends with them.

There is no OAS payable to a surviving spouse based on the deceased's entitlement. The Allowance for the Survivor (covered below) is a separate, income-tested benefit with its own age window and its own rules. It is not "the OAS survivor pension" — it is a different program that happens to be in the same family of Service Canada benefits.

If you are checking the basics for an executor checklist, see our piece on what an executor does in Canada for the broader context.

The month-of-death rule #

OAS is generally payable for the full month in which the recipient dies. The Service Canada working rule is that the payment for the month of death is retained by the estate; the payment for the month after the death is not payable and must be returned if deposited.^[4]

Two practical points:

• Because OAS deposits land near the end of each month, the month-of-death payment is often already in the account by the time the death occurs. The executor does not need to return it.
• If the deposit for the following month has already landed before the executor notifies Service Canada, the agency will request the funds back. The executor should keep the amount segregated and not distribute it as part of the estate.

The same end-of-month rule applies to the Guaranteed Income Supplement and to the Allowance and Allowance for the Survivor where the deceased was receiving any of these.^[5]

What an executor needs to do #

The notification sequence most executors follow:

1. Obtain the death certificate (or interim funeral-director's statement, where the certificate has not yet been issued). Service Canada will accept either.
2. Notify Service Canada within the first month after death by phone at 1-800-277-9914, in person at a Service Canada centre, or by mail.^[4]
3. Many funeral homes offer to handle the federal benefit notification as part of the standard service. If they do, confirm in writing which benefits they are notifying (CPP, OAS, GIS) — some only handle CPP.
4. Identify any overpayments. Pull two months of bank statements after the date of death and compare deposits against entitled amounts.
5. Return overpayments to Service Canada with the deceased's SIN and the date of death.

The notification automatically stops future OAS, GIS, and Allowance payments. If the deceased also received the CPP retirement pension, the same notification generally cuts off CPP — though the CPP survivor's pension is a separate application by the surviving spouse, not an automatic continuation.^[6]

The Allowance for the Survivor — a different program #

The Allowance for the Survivor is paid to low-income Canadians aged 60 to 64 who have been widowed and have not remarried or entered a new common-law relationship. It is income-tested, paid monthly, and intended as a bridge to OAS eligibility at 65.^[3]

Key features:

• Age range: strictly 60 to 64. The Allowance ends at 65 and the recipient transitions to their own OAS (and GIS, if income-qualified).
• Income test: annual income (excluding OAS itself) must be below the Service Canada threshold, which is reviewed quarterly. The threshold is generally in the low to mid five-figure range and varies by quarter.
• Residency: the surviving spouse must be a Canadian resident and have lived in Canada for at least 10 years after age 18.
• Relationship status: the recipient must remain widowed — remarriage or a new common-law relationship of more than 12 months ends the benefit.

The Allowance for the Survivor is separate from the CPP Survivor's Pension. A widowed Canadian aged 60 to 64 with limited income can potentially receive both at the same time, applying separately for each. The CPP Survivor's Pension is not income-tested and is based on the deceased contributor's CPP contributions.^[6]

GIS at death — the same month-of-death rule #

The Guaranteed Income Supplement is a top-up paid to OAS recipients with low income.^[5] At the recipient's death:

• GIS ends at the end of the month of death, the same rule as OAS.
• The executor reports the GIS-received income on the deceased's final tax return, alongside the OAS payments received in the year.
• A surviving spouse who was also receiving GIS may see their own GIS recalculated, because GIS is jointly assessed against household income for couples. Service Canada handles the recalculation automatically once the death is reported.

If the surviving spouse's GIS payment changes (typically increases, because the deceased's income no longer counts in the joint calculation), the change generally takes effect for the month after the death.

The OAS clawback and the final tax return #

OAS is subject to a federal income-based recovery tax — commonly called the OAS clawback — for higher-income recipients. The clawback threshold is reset annually by the CRA. For the deceased's final tax return, the OAS payments received from January 1 of the year of death through the month of death are reported as income, and the clawback (if any) is calculated on the deceased's net income.

If the deceased's income in the year of death was elevated by a deemed disposition (capital gains on appreciated property, the full RRSP/RRIF balance, etc.), the OAS payments received that year may be entirely or substantially clawed back. The executor should expect this when preparing the final return and budget for it from the estate, not from the survivor's funds.

A clean executor checklist #

A practical short list for an executor handling OAS at death:

1. Notify Service Canada within the first month (1-800-277-9914 or via the funeral home).
2. Confirm the notification has stopped OAS, GIS, and Allowance payments.
3. Return any payments deposited for months after the month of death.
4. Record OAS and GIS amounts received in the year of death for the final T1 return.
5. If a surviving spouse aged 60 to 64 is now widowed, point them at the Allowance for the Survivor application.
6. If a surviving spouse will apply for the CPP Survivor's Pension, that is a separate application; the OAS notification does not trigger it.

What we focus on at It's Simple Will #

It's Simple Will captures the executor-facing information that makes the OAS notification fast — the deceased's SIN, the bank account OAS lands in, and the contact details for any spousal benefits. The Life Discovery Kit is the place to record these so the executor is not searching through old mail for an SIN at the worst possible moment. The Will Creator handles the legal side of the will itself.

OAS at death is not complicated, but it is time-sensitive. The single most useful action for a Canadian household with OAS recipients is to write down where OAS lands and who to call if something happens, and to attach those details to the will or to the executor-facing Life Discovery Kit. The notification call is short. The clean-up if the call is delayed is not.
