Old Age Security

Program overview and legal framework

The Old Age Security program is a central part of Canada's public pension system, designed to provide a modest, reliable income to seniors in their retirement years. Its constitutional authority is derived from section 94A of the Constitution Act, 1867, with the specific rules and regulations detailed in the Old Age Security Act. The Minister of Employment and Social Development holds responsibility for the program, while its day-to-day administration is carried out by Service Canada through a network of offices across the country. Funding for OAS comes from the federal government's general tax revenues, meaning beneficiaries do not make direct contributions during their working lives as they do with the Canada Pension Plan. This structure ensures the pension is available to a broad range of seniors, including those with limited or no formal work history. The program operates alongside complementary benefits like the GIS and various allowances to form a safety net for older Canadians. The act defines eligibility criteria, benefit amounts, payment schedules, and the rules for the pension recovery tax. The act also authorizes the establishment of international social security agreements, which Canada has with numerous countries to coordinate pension benefits for people who have lived or worked abroad. The program's administration is a major function of Employment and Social Development Canada, with Service Canada acting as the primary delivery agent that interacts directly with millions of seniors each year.

Eligibility and enrolment

Eligibility for the Old Age Security pension is primarily based on age and residency history within Canada. To qualify, an individual must be 65 years of age or older and be a Canadian citizen or legal resident at the time their application is approved. The core requirement is a minimum of 10 years of residence in Canada after turning 18. For those who have lived in Canada for 40 years or more after age 18, the full OAS pension is payable. Partial pensions are prorated for those with between 10 and 40 years of residency, calculated by dividing the number of years of residence by 40. Since 2013, the enrolment process has become increasingly automatic, with Service Canada using data from income tax files to identify and enrol eligible seniors without requiring an application. For individuals not enrolled automatically, such as those with complex residency histories or who choose to defer, a manual application process remains available through Service Canada. Canada also has social security agreements with many other countries, which can allow periods of residence or contributions in those nations to be counted toward Canadian OAS eligibility or help qualify individuals for pensions from both countries. These agreements are particularly important for immigrants and Canadians who have worked abroad. For example, a person who worked outside the country for a Canadian employer may have that time abroad counted as Canadian residence if they return to Canada within six months of the employment ending. The specific rules under each international agreement vary, and seniors with such histories often need to apply manually rather than through automatic enrolment.

• Must be 65 years of age or older.
• Must be a Canadian citizen or legal resident.
• Requires a minimum of 10 years of residence in Canada after age 18.
• A full pension requires 40 years of residence in Canada after age 18.
• Partial pensions are prorated based on years of residence (e.g., 34 years yields 85% of full pension).
• Automatic enrolment since 2013 using tax data.
• Manual applications are available if not enrolled automatically.
• International social security agreements may affect eligibility.

Payment amounts and quarterly adjustments

The amount of Old Age Security pension a senior receives depends on their age, how long they have lived in Canada, and their income level. Payment amounts are reviewed and adjusted quarterly in January, April, July, and October to reflect changes in the cost of living as measured by the Consumer Price Index. For the October to December 2026 quarter, the maximum monthly OAS payment increased by 1.4 percent. This resulted in a new maximum of $762.50 per month for beneficiaries aged 65 to 74, and $838.75 per month for those aged 75 and over. The higher base amount for seniors 75 and older reflects a permanent 10 percent boost introduced in July 2022, upon which all subsequent CPI adjustments are applied. Seniors with residency periods of less than 40 years receive a prorated portion of these maximum amounts. The quarterly adjustment process is designed to protect the purchasing power of seniors' benefits against inflation. The increase is calculated by comparing the average CPI for the three-month period ending in the previous quarter to the average from a year earlier. The GIS and the Allowance benefits also receive the same CPI adjustment, applied to their respective maximum payment amounts each quarter.

Payment schedule and administration

Old Age Security pensions are paid monthly, on the third business day from the end of the current month. In December, the payment is made about one week earlier than other months. The government strongly encourages and prefers the use of direct deposit, which ensures funds are available in the recipient's bank account on the scheduled payment date. For those who receive payments by paper cheque, the arrival date depends on postal delivery times. The payment date for December is typically advanced to earlier in the month, such as December 22 in 2026, to account for the holiday season. Seniors can view their specific payment information and manage their banking details for direct deposit through their My Service Canada Account. Operational details ensure all Canadians receive their payments at approximately the same time. Direct deposits are processed to be available shortly after midnight Pacific time on the payment date, regardless of the recipient's time zone. This unpublished detail guarantees uniformity across the country. Service Canada added the ability for OAS recipients to set up or change their direct deposit information online through My Service Canada Account in September 2026, a move aimed at increasing convenience and reducing administrative delays. For issues with payments or changes to Canada Pension Plan banking information, seniors must still contact Service Canada by phone or visit an office.

Supplementary benefits: GIS and allowances

The Old Age Security program is augmented by several income-tested benefits designed to provide additional support to seniors with little to no other income. The Guaranteed Income Supplement is a monthly non-taxable benefit added to the OAS pension for low-income seniors. Eligibility for GIS is determined annually based on the recipient's income from the previous year, and the amount is adjusted each July. For single seniors in the October to December 2026 quarter, the maximum monthly GIS increased by 1.4 percent to about $1,138.89. The program also includes the Allowance, which provides support to the low-income spouse or common-law partner of an OAS pensioner, and the Allowance for the Survivor, for low-income widows and widowers aged 60 to 64. These allowances are also non-taxable and saw their maximums rise to about $1,448.05 and $1,726.17 per month, respectively, for the same quarter. Unlike the OAS pension, these supplementary benefits are not subject to the pension recovery tax, meaning low-income seniors keep the full amount of any increase. The GIS amount for a single senior is larger than the OAS pension increase, and because it is not taxed, the net benefit is greater for those with the lowest incomes. Eligibility for the GIS and allowances is reassessed every July based on the prior year's net income reported to the Canada Revenue Agency. Some seniors are automatically enrolled for GIS when they are enrolled for OAS, while others must apply separately.

Taxation and the pension recovery tax

The basic Old Age Security pension is considered taxable income and must be reported on a recipient's annual income tax return. However, a significant feature of the program is the pension recovery tax, commonly known as the clawback. This provision reduces the OAS pension for seniors whose net world income exceeds a set threshold. For the period from July 2026 to June 2027, the threshold is $93,454, based on 2025 income. The OAS pension is reduced by 15 cents for every dollar of income above this threshold. If a senior's income is high enough, the entire OAS pension can be clawed back. This recovery tax is applied at source, meaning the net amount deposited into a senior's account is already reduced. The clawback threshold is fixed for a twelve-month period from July to June, regardless of quarterly CPI increases to the OAS payment amount. This means a senior whose income places them in partial clawback territory will have 15 percent of any new OAS increase withheld before it reaches their bank account, on top of the regular income tax owed on the remainder. the GIS, Allowance, and Allowance for the Survivor are not subject to income tax or the clawback. The interaction of taxation and the clawback means that the net benefit of a quarterly CPI increase can vary significantly among seniors.

Deferral and special circumstances

Seniors have the option to defer receiving their Old Age Security pension for up to five years after becoming eligible at age 65, with payments starting automatically at age 70 if not begun earlier. For each month of deferral, the monthly pension amount increases by 0.6 percent, which translates to an annual increase of 7.2 percent. The maximum increase for deferring until age 70 is 36 percent. This can be a valuable strategy for seniors who continue to work or have other sources of income. Deferral can be requested through a My Service Canada Account or by returning the automatic enrolment letter. Special circumstances also affect OAS eligibility and amounts, such as living or working outside Canada. Canada's international social security agreements can help individuals qualify for benefits by allowing them to combine periods of residency or contribution from another country with their Canadian record. Survivors of OAS recipients may be eligible for the Allowance for the Survivor, and low-income spouses aged 60 to 64 may qualify for the Allowance, both of which provide support until the recipient becomes eligible for their own OAS pension at 65. The rules for spousal and survivor benefits are complex and depend heavily on individual income and marital status.

Interaction with other retirement income

The Old Age Security pension is one part of a multi-layered retirement income system in Canada. It is distinct from the Canada Pension Plan, which is an earnings-based contributory program. Many seniors receive both OAS and CPP benefits, and the payments are typically deposited on the same monthly schedule for convenience. When planning retirement income, it is important to understand that the average CPP retirement pension for a new 65-year-old beneficiary was $858.34 per month as of July 2026, which is considerably less than the maximum of $1,507.65. The OAS pension provides a base level of support that is not dependent on an individual's work history or earnings. For low-income seniors, the combination of OAS and GIS is critical. The GIS amount is affected by the recipient's marital status and their spouse's income, if applicable. The entire OAS payment can be eliminated through the recovery tax for individuals with very high incomes. Seniors are encouraged to use tools like the Service Canada Old Age Security Benefits Estimator to calculate their expected payments based on their specific age, residency history, and income. This helps in financial planning and understanding how changes in income, such as from part-time work or investment returns, might affect their net benefits from the program.

Questions about Old Age Security

How much is the Old Age Security pension per month in 2026?

For the October to December 2026 quarter, the maximum monthly OAS payment is $762.50 for seniors aged 65 to 74. For those aged 75 and over, the maximum monthly payment is higher at $838.75. These amounts are adjusted quarterly based on the Consumer Price Index. Most seniors receive a prorated amount if they have not lived in Canada for 40 years after age 18, and high-income seniors may have part or all of their pension clawed back.

How do I apply for Old Age Security?

Many Canadians are enrolled automatically for Old Age Security when they turn 65, as Service Canada uses income tax data to identify eligible individuals. If you are automatically enrolled, you will receive a letter from Service Canada the month after you turn 64. If you do not receive a letter or need to apply manually due to a complex residency history or a decision to defer, you can apply online through your My Service Canada Account. You can also submit a paper application by mail to Service Canada.

What is the difference between OAS and the Guaranteed Income Supplement (GIS)?

Old Age Security is a basic pension available to most seniors aged 65 and older based on age and residency. The Guaranteed Income Supplement is an additional, non-taxable benefit paid on top of OAS to seniors with very low income. Eligibility for GIS is determined annually based on the previous year's income, and it is designed to provide extra support to those who need it most. Unlike OAS, GIS payments are not subject to income tax or the pension recovery tax.

Can my OAS pension be taken away if my income is too high?

Yes, through a mechanism called the pension recovery tax or clawback. If your net world income exceeds a set threshold ($93,454 for the period July 2026 to June 2027), your OAS pension is reduced by 15 cents for every dollar of income above that threshold. If your income is sufficiently high, your entire OAS pension can be clawed back. This reduction is applied before the payment is deposited into your account. The GIS and related allowances are not subject to this clawback.

When are OAS payments deposited each month?

OAS payments are deposited on the third business day from the end of the current month. In December, the payment is made about one week earlier. In 2026, payments are made on 12 specific dates, synchronized with Canada Pension Plan and Guaranteed Income Supplement payments, including October 28, November 26, and December 22. The government recommends direct deposit to ensure timely receipt.

Is it possible to delay receiving OAS to get a larger payment later?

Yes, you can defer your Old Age Security pension for up to five years after you become eligible at age 65, with payments starting automatically at age 70 if not begun earlier. For each month you defer, your monthly pension increases by 0.6 percent, which adds up to a 7.2 percent increase per year. If you defer until age 70, you can receive a maximum increase of 36 percent. You can request deferral through your My Service Canada Account or by returning your automatic enrolment letter.
