Introduction

Old Age Security (OAS) is a non-contributory monthly pension paid by the Government of Canada. It’s based on age and years of residence in Canada, not on work history. Many people mix up OAS with the Canada Pension Plan (CPP) — they’re different. OAS is available from age 65. You can take it then, or delay until 70 for a higher monthly amount. This guide gives a step-by-step approach to the application process in 2026, plus practical tips and common pitfalls to avoid.

Prerequisites — what you need before you start

Before you begin the application you’ll want to gather documents and check eligibility. Here’s the minimum checklist:

  • Proof of identity and age: birth certificate, passport, or other government ID.
  • Social Insurance Number (SIN).
  • Proof of Canadian status: birth certificate if born in Canada; if immigrated, proof of landing (Record of Landing, Confirmation of Permanent Residence, PR card), or citizenship certificate.
  • Proof of residence history if you lived outside Canada for long periods — immigration documents, passports, utility bills, tax records.
  • Banking information for direct deposit (void cheque or banking details).
  • If applicable, documents showing name changes, marital status, or spouse’s death certificate.

Start up to six months before you turn 65 — that gives Service Canada time to ask for missing documents so your payments don't get delayed.

Step-by-step: How to apply for OAS in Canada (2026)

You can apply online through My Service Canada Account (my preferred route), by mail with the paper form, or in person at a Service Canada Centre. Follow these steps.

  1. Check basic eligibility. You must be 65 or older, and have lived in Canada for at least 10 years after turning 18 to receive OAS while living in Canada. If you live outside Canada, you generally need 20 years of residence after age 18 to keep receiving OAS.
  2. Create or sign in to My Service Canada Account (MSCA). Go to https://www.canada.ca/en/employment-social-development/services/my-account.html. MSCA lets you apply online, upload documents, check status, and receive messages from Service Canada. If you don’t have MSCA, register now — allow several days for identity verification.
  3. Gather documents listed above. Scan or take clear photos if applying online. Keep originals handy in case Service Canada asks to see them later.
  4. Start the online application. In MSCA, select “Apply for Old Age Security (OAS) pension” and follow the guided form. If you prefer paper, download and complete the Application for the Old Age Security Pension (ISP‑3250) from the OAS page: https://www.canada.ca/en/services/benefits/publicpensions/cpp/old-age-security.html.
  5. Decide whether to apply for GIS and allowances. The Guaranteed Income Supplement (GIS) is income‑tested and paid to low-income OAS recipients. The online application will offer to include GIS; tick the box and provide your spouse’s income information if applicable. If you apply by mail, include the GIS sections on the ISP‑3250.
  6. Choose direct deposit. Provide banking details so payments go straight to your account. It’s secure and faster than cheques.
  7. Submit and track your application. Keep copies of everything. Expect Service Canada to respond if they need more documents. Processing can take from a few weeks to a few months, so applying six months early helps avoid any gaps in your income.
  8. Respond to follow‑up quickly. If Service Canada requests additional proof, send it promptly. Delays here slow the start of your pension.
  9. If you live outside Canada. Apply by mail if required. Use the international postal address on the official OAS page. Note residency rules for eligibility while abroad (20 years in most cases).
  10. If you want to defer OAS. You can delay receipt up to age 70. To defer, use your MSCA or notify Service Canada. If you delay OAS, your pension rises by 0.6% per month (about 7.2% a year), up to a 36% increase if you wait until age 70.

What it costs

There’s no fee to apply. OAS payments are taxable income. If your net world income is above the OAS recovery threshold, part or all of your OAS may be recovered through the OAS recovery tax (clawback) — the recovery is calculated on your tax return. For details and the current recovery threshold, check the official OAS pages and the latest Canada Revenue Agency guidance when preparing your taxes.

Tips for a smoother application

  • Apply online via MSCA — it’s faster and you get updates in one place.
  • Apply 6 months before turning 65 so your payments start on time.
  • Apply for GIS at the same time if your income is low — you won’t get GIS automatically without applying (even if eligible).
  • Consider deferring OAS only if you expect to live long enough to benefit from the higher monthly amount — do the math. Deferral raises monthly payments by 0.6% per month.
  • Keep a clear record of your residence history — Service Canada often asks for proof when you spent time outside Canada.
  • If married or common-law, report your spouse’s income when applying for GIS — their income affects your GIS eligibility.

Common mistakes to avoid

  • Waiting until after 65 to apply. That leads to delayed payments — apply 6 months ahead.
  • Forgetting to apply for GIS. Many miss out because GIS isn’t automatic.
  • Sending incomplete supporting documents. Service Canada will request missing items and delay processing.
  • Confusing CPP and OAS. They’re separate programs with separate applications and rules.
  • Not updating address or banking info. Payments can be delayed or mailed to the wrong place.
  • Assuming eligibility while living abroad. Different residency rules apply — check before you leave.
