The old age security program is one of the most important retirement income systems in Canada. It provides monthly financial support to seniors to help them manage living expenses after retirement. Unlike private pensions or employment-based retirement plans, the old age security system is funded by the government and is designed to support older citizens regardless of their work history.
This detailed guide explains everything about old age security, including eligibility rules, payment amounts, application process, income thresholds, benefits, and important updates that retirees should know.
What Is Old Age Security?
The old age security program (OAS) is a monthly pension provided by the Government of Canada to seniors aged 65 and older. It is one of the foundational pillars of Canada’s retirement income system.
Key Features of Old Age Security:
- Monthly pension payments
- Based on age and residency (not employment history)
- Available to most Canadian seniors
- Adjusted quarterly for inflation
- Taxable income
Unlike other retirement programs, you do not need to have worked or contributed directly to receive old age security benefits.
Why Old Age Security Is Important

The old age security program plays a critical role in supporting financial stability for seniors. As people age, their income often decreases while healthcare and living costs increase.
Importance of OAS:
- Helps reduce senior poverty
- Provides stable monthly income
- Supports basic living expenses
- Works alongside other benefits like CPP
- Adjusts with inflation over time
For many retirees, old age security is a key part of their monthly budget.
Old Age Security Eligibility Requirements
To qualify for old age security, applicants must meet certain conditions set by the Canadian government.
Age Requirement
You must be at least 65 years old to receive old age security payments.
Residency Requirement
Eligibility is based on how long you have lived in Canada.
Basic Rule:
- At least 10 years of residency in Canada after age 18 (for partial pension)
For Full Pension:
- 40 years of residency in Canada after age 18
The longer you live in Canada, the higher your old age security benefit may be.
Citizenship or Legal Status
You must be:
- A Canadian citizen OR
- A legal resident at the time your application is approved
How Old Age Security Payments Work

The old age security program provides monthly payments, usually deposited directly into your bank account.
Payment Frequency
- Monthly payments (usually on the last business week of each month)
Payment Method
- Direct deposit (preferred)
- Cheque (less common)
Old Age Security Payment Amount
The amount you receive depends on your age and residency history.
Basic Structure:
- Full pension for long-term residents
- Partial pension for shorter residency periods
Payments are reviewed regularly and adjusted based on inflation.
Old Age Security and Income Thresholds
One important feature of old age security is the income-based clawback system.
What Is the OAS Clawback?
If your income is above a certain limit, you may need to repay part or all of your old age security benefits.
High-Income Threshold
- If income exceeds a set annual limit, OAS is reduced
- Higher income = lower or no OAS payment
This ensures that the program supports seniors who need it most.

Canada Pension Plan (CPP)

- Increased lifetime benefits for longer-living individuals
Maximum Deferral Period
- Up to 60 months (5 years) after age 65
This option is useful for those who do not need immediate income.
Taxation of Old Age Security

What This Means:
- You must report OAS on your tax return

Proper tax planning is important for retirees.
