Requirements for Old Age Security in Canada in 2026

Old Age Security (OAS) is a monthly pension paid by the federal government to most Canadians aged 65 and older. Unlike the Canada Pension Plan (CPP), OAS is not based on your employment history or contributions — it is funded through general tax revenues and tied mainly to how long you have lived in Canada.

Applying for OAS is straightforward for most people, but gathering the right documents and understanding the eligibility rules ahead of time will help you avoid delays. The program is administered by Service Canada, and in many cases you will be automatically enrolled. If you are not enrolled automatically, you will need to submit a formal application.

What this procedure is and what it’s for

Old Age Security (OAS) is a federal pension program that provides a monthly taxable benefit to eligible Canadians and permanent residents who are 65 years of age or older. It is one of the main pillars of Canada’s retirement income system, alongside the Canada Pension Plan (CPP) and personal savings.

OAS applies to you if:

• You are 65 years of age or older.
• You are a Canadian citizen or a legal resident of Canada at the time your application is approved.
• You have lived in Canada for at least 10 years after the age of 18 (if you currently live in Canada).
• You have lived in Canada for at least 20 years after the age of 18 (if you currently live outside Canada).

The amount you receive depends on how long you have lived in Canada after age 18. A full OAS pension requires 40 years of Canadian residence after age 18. Partial pensions are available if you have lived in Canada for at least 10 years.

You may also be eligible for the Guaranteed Income Supplement (GIS), a non-taxable monthly benefit for low-income OAS recipients who live in Canada. GIS is applied for at the same time as OAS.

The official body responsible for OAS is Service Canada, which operates on behalf of Employment and Social Development Canada (ESDC). Applications can be submitted online, by mail, or in person at a Service Canada Centre.

Documents required

The documents you need depend on your situation. Below is a complete list. Always bring originals when submitting in person; keep photocopies for your records.

For all applicants

• Proof of age: birth certificate, Canadian passport, or other government-issued document showing your date of birth.

• Proof of Canadian citizenship or legal status: Canadian citizenship certificate, Canadian passport, or Permanent Resident card.

• Social Insurance Number (SIN): your SIN card or a document showing your SIN (e.g., a tax notice of assessment from the Canada Revenue Agency).

• Proof of residence history in Canada: if your residency history is not fully on record with Service Canada, you may need documents such as school records, employment records, tax returns, or immigration documents showing dates of entry and exit.

If you lived outside Canada

• Proof of legal status in the country where you resided: immigration documents, foreign residence permits, or equivalent.

• Proof of periods of residence or contributions in a country that has a social security agreement with Canada: foreign pension statements or official letters from the foreign social security authority. Documents in a language other than English or French must be accompanied by a certified translation into English or French.

If you are applying for the Guaranteed Income Supplement (GIS)

• Proof of income: your most recent Notice of Assessment from the Canada Revenue Agency (CRA), or details of all income sources if you did not file a tax return.
• If your income has decreased since the previous tax year, you may need proof of the change (e.g., a letter confirming retirement, a Record of Employment, or a statement showing reduced pension income).

If you are applying on behalf of someone else

• Legal authority to act: power of attorney, a court order, or other legal document confirming your authority to act on the applicant’s behalf.
• Your own government-issued photo ID.

Note: Service Canada may request additional documents depending on your individual circumstances. Originals are preferred; certified copies are accepted where originals cannot be provided.

Steps to complete the procedure

1. Check whether you have been automatically enrolled. Service Canada automatically enrolls some eligible Canadians and sends a notification letter at age 64. Check your My Service Canada Account (MSCA) or wait for a letter. If you receive a letter confirming automatic enrolment, no further action is needed unless you want to defer your pension.

2. Determine your preferred application method. You can apply:

   • Online through your My Service Canada Account (MSCA) at canada.ca/my-service-canada-account.
   • By completing the paper form ISP-3000 (Application for the Old Age Security Pension), available at any Service Canada Centre or downloadable from the Service Canada website.
   • In person at a Service Canada Centre. No appointment is required for most visits, but booking one online or by phone (1-800-277-9914) can reduce wait times.

3. Gather all required documents as listed in the section above before starting your application.

4. Complete the application form. If applying online, log in to MSCA and follow the guided steps. If using the paper form, fill it out carefully in block letters and sign it.

5. Submit your application.

   • Online: submit directly through MSCA.
   • By mail: send the completed form and supporting documents to the Service Canada office listed on the form for your province or territory.
   • In person: bring your completed form and original documents to a Service Canada Centre.

6. Apply for the Guaranteed Income Supplement (GIS) at the same time if your income is low. GIS is included in the OAS application package.

7. Track your application. Once submitted, you can check the status of your application through your MSCA account or by calling Service Canada.

You can apply up to 11 months before you want your pension to start. Service Canada recommends applying at least 6 months before your 65th birthday if you are not automatically enrolled.

You may also choose to defer your OAS pension by up to 5 years (until age 70) to receive a higher monthly amount — 0.6% more for each month of deferral, up to a maximum increase of 36%.

Fees and timelines

• Application fee: there is no fee to apply for OAS. The program is entirely government-funded.

• Processing time: Service Canada aims to process complete applications within 7 to 12 weeks. Processing may take longer if documents are missing or if your residency history needs to be verified.

• First payment: if approved, your first payment is typically issued the month after your application is processed and your eligibility date is confirmed.

• Validity: OAS is an ongoing monthly benefit. There is no expiry date, but you must continue to meet residency and legal status requirements. GIS must be renewed annually (this is done automatically if you file your income tax return each year with the CRA).

• Payment amounts (2026): OAS payment amounts are adjusted quarterly based on the Consumer Price Index. As of early 2026, the maximum monthly OAS pension for recipients aged 65–74 is approximately $727.67, and for those aged 75 and over approximately $800.44. Verify current rates at canada.ca/en/services/benefits/publicpensions/cpp/old-age-security/payments.html.

• OAS Recovery Tax (clawback): if your net annual income exceeds the threshold set by the CRA (approximately $90,997 for the 2025 income year, applied in 2026), part or all of your OAS may be recovered through a repayment tax. Check the current threshold with the CRA each year.

Common mistakes and how to avoid them

• Applying too late and losing retroactive payments. OAS can be paid retroactively for a maximum of 11 months before the date Service Canada receives your application. If you delay applying, you may lose months of payments you were entitled to. Apply as soon as you are eligible or up to 11 months in advance.

• Not documenting periods spent outside Canada. If you have lived or worked abroad, you must account for those years. Failing to provide proof of your Canadian residence history — or proof of residence in a country with a social security agreement — can result in a reduced pension or a rejected application. Gather immigration records, tax returns and employment documents well in advance.

• Forgetting to apply for the Guaranteed Income Supplement (GIS). GIS is not automatic. If you have a low income, you must request it as part of your OAS application. Many eligible seniors miss out on GIS simply because they did not know to ask for it.

• Not filing an annual income tax return with the CRA. GIS eligibility is reassessed each year based on your income tax return. If you do not file a return by the deadline (generally 30 April of each year), your GIS payments may be interrupted. Even if you have little or no income, filing a return is essential to maintain GIS.

Frequently asked questions

Do I need to have worked in Canada to receive OAS? No. OAS is not based on employment history or contributions. Eligibility depends on your age and how long you have lived in Canada after age 18, not on whether you worked or paid into any pension plan.

Can I receive OAS if I live outside Canada? Yes, if you lived in Canada for at least 20 years after age 18 and you are a Canadian citizen or legal resident at the time you left Canada. Canada also has social security agreements with many countries that may help you qualify if you do not meet the 20-year rule on your own.

What happens if I defer my OAS past age 65? You can delay receiving OAS by up to 60 months (until age 70). For each month you defer, your monthly pension increases by 0.6%, for a maximum increase of 36% at age 70. Deferring can be beneficial if you are still working and have a higher income. You cannot defer OAS past age 70.

Will my OAS be reduced if I have other income? OAS itself is not reduced based on income, but if your net annual income exceeds the OAS Recovery Tax threshold (approximately $90,997 for the 2025 income year), you must repay part or all of your OAS through your income tax return. This is sometimes called the OAS clawback.

How do I update my banking information for OAS payments? You can update your direct deposit information through your My Service Canada Account (MSCA) online, by calling Service Canada at 1-800-277-9914, or in person at a Service Canada Centre.

What to do next

The most important step is to confirm whether Service Canada has already enrolled you automatically by checking your My Service Canada Account (MSCA) or waiting for a letter around your 64th birthday. If you are not automatically enrolled, gather your proof of age, proof of citizenship or legal status, and Social Insurance Number — these are the three documents almost every applicant needs — and submit your application at least 6 months before you turn 65.

If your income is low, remember to apply for the Guaranteed Income Supplement (GIS) at the same time.

Requirements, payment amounts and income thresholds can change. Always verify the most current information directly with Service Canada at canada.ca/en/services/benefits/publicpensions/cpp/old-age-security.html or by calling 1-800-277-9914 before submitting your application.
