Service Canada periodically sends proof-of-life and income attestation forms to OAS and GIS recipients. In 2026, the volume of these requests has increased, and the response window has tightened.
Choose what to update first
A late response, a missed form, or an outdated address can pause your payment for weeks while reinstatement is processed.
This guide explains what these proof requests mean, how to respond, and what to do if you have already missed one. There is no app and no cost.
The information is drawn from Service Canada procedures and is verified quarterly; confirm current forms, addresses and response windows on the official site before acting.
Keep a personal record of every form received, the date you responded, and the confirmation number, so you have proof if Service Canada later disputes receipt.
What proof updates are and why they matter
Proof updates are how Service Canada confirms that an OAS or GIS recipient is still alive, still resident in Canada, and still meets the income test for GIS. There are three types:
- Proof of life — for seniors over 75 or those living abroad
- Income attestation — for GIS recipients
- Residency confirmation — for those outside Canada for more than six months
These requests are sent by mail to the address on your Service Canada record and are not optional.
If you do not respond by the deadline stated on the form, your payment is suspended. Reinstatement requires a new application, additional documentation, and a 4 to 8 week waiting period.
Service Canada does not send reminders. If the form is lost in the mail, or arrives at an outdated address, the payment is suspended on the deadline with no grace period.
| Form type | Who receives it | Response method |
|---|---|---|
| Proof of life | OAS recipients 75+ | Mail or online signature |
| Income attestation | GIS recipients | Tax return or signed form |
| Foreign residency | Recipients abroad 6+ months | Mail with witness signature |
How to respond and what happens if you miss the deadline
When a proof request is not returned by the deadline, your payment is suspended on the next scheduled date. You are not notified by email, text, or phone.
The only way to find out is to check your bank statement for a missing deposit, or to log into My Service Canada Account and see a suspended status.
Reinstatement takes 4 to 8 weeks; the form must be re-submitted with a written explanation, and Service Canada may request additional documentation. The payment gap is not back-paid automatically.
You have three options to return the form:
- Mail — the slowest, with the highest risk of loss.
- Online signature (My Service Canada Account) — fastest and creates a digital record.
- In-person at a Service Canada Centre — takes a few minutes but requires travel.
Online is the recommended method: log in, open the message that references the proof request, complete the form fields, sign electronically, and submit. You will receive a confirmation email within minutes.
Common mistakes to avoid
- Ignoring the form — assuming it is junk mail. Proof requests come in plain envelopes from Service Canada. Open everything from them.
- Signing in the wrong place — the signature line is on the second page, not the first. Read the whole form before signing.
- Missing the deadline by days — the deadline is a hard cutoff. Plan to respond at least 7 days before.
- Not confirming submission — if you mail the form, retain the tracking number. If you submit online, save the confirmation email. Without proof of submission, Service Canada will treat the form as not received.
