If you're approaching 65 — or already there — the Old Age Security pension is likely one of the first government payments you'll receive in retirement. Unlike the Canada Pension Plan (CPP), which is based on your work history and contributions, the OAS is based on how long you've lived in Canada. You don't need to have worked a single day to qualify. Understanding your OAS eligibility in Canada in 2026 matters because the rules around residency, automatic enrolment, clawback thresholds, and deferral options affect how much you actually receive. This guide covers everything you need to know.

Many Canadians are automatically enrolled for OAS. Service Canada uses your tax filing and other government records to determine eligibility. If you're automatically enrolled, you'll receive a letter around your 64th birthday informing you that your OAS pension will begin the month after you turn 65.

You're likely to be auto-enrolled if:

To qualify for full OAS while living in Canada, you must:

If you've lived in Canada for at least 10 years after age 18, you qualify for a partial OAS (calculated as 1/40th of the full amount per year of Canadian residency). If you've lived in Canada for 40 years or more after age 18, you receive the full OAS.

If you plan to retire abroad, you can still receive OAS if:

If you lived in Canada for 10–19 years, you'll receive OAS only while living in Canada. If you leave, payments stop (with some exceptions during temporary absences).

What If I Don't Qualify Automatically?

You need to apply manually if:

OAS amounts are indexed quarterly. For Q1 2026 (January–March):

Seniors 75+ receive a 10% increase above the standard OAS amount, effective since July 2022.

If you lived in Canada for fewer than 40 years after age 18, you receive a proportional amount:

OAS is adjusted every three months (January, April, July, October) based on the Consumer Price Index. The amount can go up but never goes down — the OAS includes a guaranteed floor (if CPI drops, your payment stays the same).

The OAS Clawback (Recovery Tax)

What Is the Clawback?

If your individual net income exceeds a certain threshold, you must repay part or all of your OAS through the OAS recovery tax (commonly called the "clawback"). This is calculated on your tax return and deducted from your OAS payments the following year.

For the 2025 income year (affecting your 2026 OAS payments):

For every dollar of net income above ~$90,997, you repay 15 cents in OAS.

Income splitting with your spouse (pension income splitting, spousal RRSP) TFSA withdrawals — TFSA income doesn't count toward the clawback Timing RRSP conversions to minimise annual income spikes Deferring OAS to age 70 if you're still working and earning above the threshold

You can delay your OAS start by up to 5 years (from age 65 to age 70). For each month you defer, your OAS increases by 0.6% — or 7.2% per year.

If you defer the full 5 years:

You have other income sources (CPP, employer pension, savings)

You're in good health and expect a long retirement

When it doesn't make sense:

OAS unlocks access to several additional benefits for low-income seniors:

Guaranteed Income Supplement (GIS) eligibility

Margaret is 66 and has lived in Canada her entire life (48 years after turning 18). She receives the full OAS of $727.67/month. Her only income is CPP ($850/month) and a small RRSP withdrawal ($400/month). Her total annual net income is about $23,700 — well below the clawback threshold of ~$90,997. She also qualifies for the GIS because her income (excluding OAS) is below the GIS threshold. Between OAS, GIS, CPP, and the GST/HST credit, Margaret receives about $24,000/year. GIS eligibility

Chen arrived in Canada as a permanent resident at age 45. He's now 67 and has lived in Canada for 22 years after turning 18. His OAS is calculated as: 22/40 × $727.67 = ~$400/month (partial OAS). Chen also has a small CPP pension from his 22 years of working in Canada ($550/month) and no other retirement savings. With his low income, he qualifies for GIS to supplement his partial OAS. His combined government income (partial OAS + GIS + CPP + GST/HST credit) totals about $19,000/year. Chen could have had a higher OAS if Canada had a social security agreement with his country of origin that allowed him to count residency years abroad — worth investigating for anyone in a similar situation.

Is OAS the same as CPP?

No. CPP (Canada Pension Plan) is based on your employment contributions during your working years. OAS is based on years of residency in Canada and doesn't require any work history. Most retirees receive both, but they're separate programs.

Do I have to apply for OAS?

Many people are automatically enrolled and receive a letter around age 64. If you don't receive one, you need to apply manually through My Service Canada Account or by mail. If you want to defer your start date, you also need to inform Service Canada.

Is OAS taxable?

Yes. Unlike some benefits (CCB, GST/HST credit), OAS is taxable income. It's included in your net income and can affect your eligibility for income-tested benefits like GIS.

Can I receive OAS while still working?

Yes. There's no requirement to stop working to receive OAS. However, if your employment income pushes your total net income above ~$90,997, the clawback applies and you'll repay part of your OAS.

I was outside Canada for a few years. Does that affect my OAS?

It depends on how long. If you still have at least 10 years of residency after age 18, you qualify for partial OAS. Each year of residency = 1/40th of the full amount. Extended absences reduce your residency years and therefore your OAS.

Check whether you've been auto-enrolled. If you're 63–64, look for a letter from Service Canada. If you haven't received one by age 64, apply manually. Decide whether to defer. If you're still working or have other income, deferring to 67–70 could increase your lifetime OAS. Use Benefit Check to model scenarios. File your tax return every year. OAS is income-tested for the clawback, and GIS eligibility requires annual filing. File your 2025 taxes by April 30, 2026 to keep benefits Check if you qualify for GIS. If your income is low, GIS can add hundreds per month on top of OAS. Guaranteed Income Supplement eligibility
