OAS Eligibility 2026: residence, age and legal status

Eligibility for Old Age Security rests on three conditions: being 65 or older, having resided in Canada for long enough after the age of eighteen, and having legal status. Ten years of residence are enough to start the pension while living in Canada; twenty are needed to receive it abroad or to keep it after leaving. The amount is set by the same count of years, one fortieth of the full pension for each complete year, with the full pension at forty years. Residence is not the same as presence: it means making your home in Canada, and some periods abroad, such as service with the Canadian Forces or work for a Canadian employer, still count. Social security agreements can help reach the minimum without changing how the Canadian pension is calculated. This guide covers each condition, the older rules that still explain some full pensions, sponsorship, and how enrolment works. Read more

The conditions in short

• Age: 65 or older. There is no early OAS pension; at 60 to 64, only the Allowance and the Allowance for the Survivor exist.
• Residence: at least 10 years in Canada after age 18 if you live in Canada when you apply, at least 20 years if you live abroad.
• Status: Canadian citizen or legal resident on the day before approval, or on the day before you left Canada.
• Amount: the full pension with 40 years, one fortieth per complete year below that.

Counting your years of residence

The Old Age Security Act counts the total time you resided in Canada after your 18th birthday and before your application is approved. The periods do not need to be continuous: someone who lived here from 20 to 30 and again from 50 to 65 has 25 years. The total is rounded down to complete years, so 24 years and 11 months gives a pension of 24/40.

Some absences do not interrupt residence. Temporary absences of up to a year, for a holiday, a family matter or medical treatment, generally do not, and the regulations treat certain periods abroad as residence: service with the Canadian Forces, employment abroad with a Canadian employer, or accompanying a spouse in either case, provided you returned to Canada within six months of the end of the posting or turned 65 during it. Service Canada assesses these on the evidence you supply: passports, leases, tax returns, letters from employers.

Each year matters directly. For October to December 2026, 12 years give $228.75 a month at 65, 31 years $590.94. Since the partial pension is fixed when it starts and never increases afterwards for later years of residence, a person short of 40 years who keeps living in Canada can gain by deferring, as the OAS deferral guide explains.

The older full-pension rules

Before July 1977 the full pension required only 10 years of residence. People who were already adults living in Canada then kept a transitional right: someone who was 25 or older on 1 July 1977 and resided in Canada at that date, or had resided here after 18, can receive the full pension with 10 years of residence immediately before approval, or with shorter recent residence offset by earlier years at three times the absence. Anyone turning 65 in 2026 was born in 1961 and was 16 in July 1977, so this route is now closed to new applicants; it still explains why some older relatives receive a full pension with fewer than 40 years.

Living abroad: the 20-year threshold

Where you live when the pension starts, and afterwards, changes the minimum. A person living in Canada can start with 10 years. A person living abroad needs 20 years of residence in Canada after 18 to receive it outside the country. The same threshold governs pensioners who leave: with 20 years or more, the pension follows you anywhere, without time limit; with fewer, it is paid for six months after the month you leave and then suspended until you come back.

Pensioners abroad must also file an Old Age Security Return of Income each year, declaring their world income, so that the recovery tax can be calculated. The Guaranteed Income Supplement and the Allowance, unlike the pension, are never paid to people who live abroad, and stop after six months of absence.

Social security agreements

Canada has agreements with many countries, among them the United States, France, Italy, Portugal, India, the Philippines and most member states of the European Union. Under an agreement, periods of residence or contribution in the other country can be added to Canadian residence to meet the minimum of 10 years (or 20 years abroad). The Canadian pension is still calculated on Canadian years only: someone with 6 years in Canada and 30 in a partner country can qualify, and receives 6/40. Because the rules differ from one agreement to the next, Service Canada assesses each case on application.

Legal status and sponsorship

The pension is reserved for citizens and people legally resident in Canada, assessed on the day before approval or on the day before leaving Canada. Time spent in Canada before obtaining legal status does not count as residence. Sponsored immigrants can receive the OAS pension once they meet the residence conditions, but not the Guaranteed Income Supplement or the Allowance while the sponsorship undertaking is in force, except in the situations listed in the regulations.

Applying

Many people never apply: Service Canada writes, usually the month after the 64th birthday, to say they will be enrolled automatically from the month after they turn 65. Those who do not receive that letter apply online through My Service Canada Account or on paper, up to eleven months before the month they want payments to start. Late applicants can receive up to eleven months of back payments. Anyone who wants to defer simply does not apply, or tells Service Canada the month they wish to start.

Once eligible, your amount is set by the OAS calculator; low incomes add the supplement calculated on the GIS calculator, and the payment calendar is on the OAS payment dates page.
