Old Age Security (OAS) Eligibility Guide
Old Age Security (OAS) is one of Canada’s most important retirement benefit programs. Unlike the Canada Pension Plan (CPP), eligibility for OAS is generally based on your age and how long you have lived in Canada rather than your employment history or pension contributions.
Every year, millions of Canadians receive Old Age Security payments to help support their retirement income. Understanding the eligibility rules can help you determine whether you qualify, when you can begin receiving payments and how much residency may affect your benefit.
What Is Old Age Security (OAS)?
Old Age Security is a monthly pension paid by the Government of Canada to eligible seniors. Unlike CPP, OAS is not based on employment earnings or payroll contributions. Instead, it is funded through general government revenues.
The program provides a basic source of retirement income for eligible Canadians and may be combined with other retirement benefits such as the Canada Pension Plan, workplace pensions and personal retirement savings.
Some OAS recipients with low income may also qualify for additional benefits such as the Guaranteed Income Supplement (GIS).
Who Can Qualify for OAS?
Eligibility for Old Age Security depends primarily on your age, your legal status in Canada and the amount of time you have lived in Canada after turning 18 years old.
Meeting the age requirement alone does not automatically guarantee eligibility. Service Canada reviews each application based on the residency rules established under the Old Age Security Act.
| Requirement | Description |
|---|---|
| Age | Generally 65 years or older. |
| Legal Status | Canadian citizen or legal resident when your application is approved, where applicable. |
| Canadian Residence | Must satisfy the required residency rules. |
| Application | Some individuals must apply, while others may be automatically enrolled. |
How Many Years Must You Live in Canada?
For individuals living in Canada, at least 10 years of residence in Canada after turning 18 is generally required to qualify for a partial Old Age Security pension.
To receive the full OAS pension while living in Canada, most people need 40 years of Canadian residence after age 18. If you have fewer years of residence, you may still qualify for a partial pension based on your residency history.
| Years of Canadian Residence After Age 18 | Possible Outcome |
|---|---|
| Less than 10 years | Generally not eligible while living in Canada. |
| 10 to 39 years | May qualify for a partial OAS pension. |
| 40 years or more | May qualify for the full OAS pension. |
Can You Receive OAS If You Live Outside Canada?
Yes, in certain circumstances. Canadians living outside Canada may still qualify for Old Age Security if they meet specific residency requirements or are covered by an international social security agreement between Canada and another country.
The eligibility rules for individuals living abroad differ from those for residents of Canada, and Service Canada reviews each situation individually.
Do You Need to Apply for OAS?
Some Canadians are automatically enrolled in Old Age Security and receive a notification from Service Canada before their 65th birthday. Others must submit an application to begin receiving benefits.
If you are unsure whether you have been automatically enrolled, you should contact Service Canada or check your My Service Canada Account before reaching age 65.
Full OAS Pension vs. Partial OAS Pension
The amount of Old Age Security you receive depends largely on how many years you have lived in Canada after turning 18. Canadians who meet the full residency requirement may qualify for the maximum monthly OAS pension, while those with fewer qualifying years may receive a partial pension.
Service Canada calculates partial pensions according to the number of eligible years of Canadian residence, subject to the rules established under the Old Age Security Act.
| Years of Residence After Age 18 | Possible OAS Benefit |
|---|---|
| 10–39 years | May qualify for a partial OAS pension. |
| 40 years or more | May qualify for the full monthly OAS pension. |
Automatic Enrolment for Old Age Security
Many Canadians no longer need to submit a separate application for Old Age Security. Service Canada automatically enrolls many eligible individuals and sends a notification letter before they reach age 65.
However, not everyone is enrolled automatically. If you do not receive a notification, you may need to apply for OAS yourself to avoid delays in receiving your pension.
| Situation | Action Required |
|---|---|
| Automatically enrolled | No application is usually required. |
| Not automatically enrolled | Submit an OAS application through Service Canada. |
| Unsure of your status | Check My Service Canada Account or contact Service Canada. |
Can You Delay Your OAS Pension?
Yes. Eligible Canadians may choose to delay the start of their Old Age Security pension beyond age 65. Delaying your pension increases your monthly OAS payment once benefits begin.
Many people consider delaying OAS if they continue working, have other retirement income or expect to benefit from receiving a larger monthly pension later in retirement.
| Starting Age | General Effect |
|---|---|
| Age 65 | Standard OAS pension begins. |
| After age 65 | Monthly OAS payment increases. |
| Up to age 70 | Maximum delayed retirement increase may apply. |
Examples of Common Residency Situations
The following examples show how different residency histories may affect eligibility for Old Age Security.
| Situation | Possible Outcome |
|---|---|
| Lived in Canada for 40 years after age 18 | May qualify for the full OAS pension. |
| Lived in Canada for 25 years after age 18 | May qualify for a partial OAS pension. |
| Recently immigrated to Canada | Eligibility depends on residency history and applicable international agreements. |
| Living outside Canada after retirement | Eligibility depends on residency requirements and international agreements. |
What Is the OAS Recovery Tax (Clawback)?
Some higher-income seniors may be required to repay part or all of their Old Age Security pension through the OAS Recovery Tax, commonly referred to as the OAS clawback.
The recovery tax is based on annual net income. If your income exceeds the government’s yearly threshold, your OAS payments may be reduced. The income threshold is reviewed and updated periodically by the Government of Canada.
| Income Level | Possible Effect |
|---|---|
| Below the recovery threshold | Full eligible OAS pension may be payable. |
| Above the recovery threshold | Some or all OAS benefits may be subject to repayment. |
How to Check Your OAS Eligibility
If you are approaching age 65 or planning your retirement, you can check your Old Age Security eligibility through My Service Canada Account (MSCA). The online portal allows eligible Canadians to review their benefit information, update personal details and determine whether they have been automatically enrolled.
Reviewing your information before reaching retirement age can help you avoid delays and ensure that any required application is submitted on time.
| Service | Available Through MSCA |
|---|---|
| Check OAS enrolment status | Yes |
| View benefit information | Yes |
| Update personal information | Yes |
| Review direct deposit details | Yes |
What If You Are Not Eligible at Age 65?
Not everyone qualifies for Old Age Security immediately upon turning 65. If you do not meet the required residency conditions, you may become eligible later after accumulating additional years of residence in Canada or through an applicable international social security agreement.
If you believe your residency history has not been assessed correctly, you can contact Service Canada to discuss your individual circumstances.
Can Immigrants Qualify for Old Age Security?
Yes. Permanent residents and Canadian citizens who immigrated to Canada may qualify for Old Age Security if they meet the residency requirements established under the Old Age Security Act.
In some cases, Canada’s international social security agreements allow periods of residence or insurance in another country to help satisfy the minimum eligibility requirements.
| Situation | Possible Eligibility |
|---|---|
| Canadian-born resident | Based on Canadian residency after age 18. |
| Permanent resident | May qualify if residency requirements are met. |
| Living outside Canada | May qualify depending on residency history and international agreements. |
| Recent immigrant | Eligibility depends on years of residence and applicable agreements. |
How OAS Fits Into Your Retirement Income
Old Age Security is designed to provide a basic level of retirement income. Many Canadians receive OAS alongside other sources of retirement income, including the Canada Pension Plan (CPP), workplace pensions, Registered Retirement Savings Plans (RRSPs), Registered Retirement Income Funds (RRIFs) and personal investments.
Considering all of your retirement income sources together can help you decide when to begin receiving OAS and whether delaying your pension may be beneficial.
| Retirement Income Source | May Be Combined with OAS? |
|---|---|
| Canada Pension Plan (CPP) | Yes |
| Guaranteed Income Supplement (GIS) | Yes, if eligible. |
| Employer Pension | Yes |
| RRSP / RRIF Income | Yes |
| Personal Investments | Yes |
