The Old Age Security (OAS) program is a cornerstone for retirement planning in Canada's public retirement income system for a modest base of retirement income.
Old Age Security (OAS): Retirement Planning Explained

Retirement Income Safety Net
The Old Age Security (OAS) program is a cornerstone of Canada's public retirement income system. This program provides a modest base upon which individuals can build their retirement income. The OAS program is funded out of the general tax revenues of the Government of Canada, which means that you do not pay into it directly.
The OAS pension is a monthly payment available to seniors aged 65 and older who meet the Canadian legal status and residence requirements. The amount of your OAS pension will be determined by how long you have lived in Canada after the age of 18. It is considered taxable income and is subject to a recovery tax if your individual net annual income is higher than the net world income threshold set for the year.
Eligibility for OAS
To be eligible for the OAS pension, you must be 65 years old or older, you must be a Canadian citizen or a legal resident at the time we approve your OAS pension application, and you must have resided in Canada for at least 10 years since the age of 18. You must also be residing in Canada and have resided in Canada for at least 20 years since the age of 18 to receive the OAS pension while outside Canada.
Even if you are not living in Canada, you may still qualify for the OAS pension. However, the 20-year residency rule applies. If you do not meet these requirements, you may still qualify for a pension if you lived or worked in a country that has a social security agreement with Canada.
Application Process
The application process for the OAS pension involves several steps. You should start the process six months before you turn 65. To apply, you will need to provide your Social Insurance Number (SIN), your birth certificate, and other documentation to prove your legal status and residence in Canada. If you have lived or worked in a country with a social insurance agreement with Canada, you may need to provide additional documentation.
Once you have gathered all the necessary documents, you can apply online or by mail. The application form will ask you for information about your work history, your income, and your marital status. It is important to answer all questions honestly and accurately, as providing false information could result in penalties.
Payment Amounts
The amount of OAS pension you receive each month depends on how long you have lived in Canada after the age of 18. The maximum monthly payment amount is determined by the Government of Canada and can change quarterly. If you have lived in Canada for less than 40 years after turning 18, you will receive a partial pension.
If your annual income is above a certain amount, you may need to pay some of your OAS pension back through the OAS recovery tax. The amount of recovery tax you have to pay depends on your annual income and marital status. If your income is below the threshold, you will not have to pay any recovery tax.
OAS Benefits
The OAS program provides several benefits to seniors in addition to the basic pension. These benefits include the Guaranteed Income Supplement (GIS), the Allowance, and the Allowance for the Survivor. These benefits are income-tested, which means that your income, and in some cases your spouse's or common-law partner's income, will determine whether you are eligible for these benefits and how much you will receive.
The GIS is a monthly non-taxable benefit that is paid to OAS pension recipients who have a low income and are living in Canada. The Allowance is a benefit available to the spouses or common-law partners of GIS recipients. The Allowance for the Survivor is a benefit available to people aged 60 to 64 who are widowed and whose income is below a certain amount.
Guaranteed Income Supplement (GIS)
The GIS is a monthly benefit paid to eligible OAS recipients who have a low income. The amount of GIS you can receive depends on your marital status and your income. If you are married or in a common-law relationship, your combined income will be considered. The GIS is non-taxable, which means you do not have to pay tax on this income.
To be eligible for the GIS, you must be receiving the OAS pension and living in Canada. You must also have an income below a certain amount, which is determined by the Government of Canada. If you are eligible, you must apply for the GIS. Once you are receiving the GIS, you will need to renew it each year by filing an income tax return.
Allowance and Allowance for the Survivor
The Allowance is a benefit available to the spouses or common-law partners of GIS recipients. To be eligible for the Allowance, you must be aged 60 to 64, your spouse or common-law partner must be receiving the GIS, and your combined income must be below a certain amount. The Allowance is also non-taxable.
The Allowance for the Survivor is a benefit available to people aged 60 to 64 who are widowed and whose income is below a certain amount. To be eligible for this benefit, you must not be remarried or in a common-law relationship. The Allowance for the Survivor is also non-taxable.
Impact on Other Benefits
The OAS pension and other OAS benefits can have an impact on other benefits you may be receiving. For example, if you are receiving the GIS and you start receiving other income, such as a private pension, your GIS amount may be reduced. Similarly, if you are receiving the Allowance and your spouse or common-law partner starts receiving other income, your Allowance amount may be reduced.
It is important to understand how the OAS program interacts with other parts of Canada's retirement income system, such as the Canada Pension Plan (CPP) and private pensions. The CPP is a contributory, earnings-related social insurance program that provides a basic level of income protection to eligible Canadians in the event of retirement. The CPP operates throughout Canada, except in Quebec, where the Quebec Pension Plan (QPP) provides similar benefits.
Interaction with Canada Pension Plan (CPP)
The OAS pension and the CPP retirement pension are two separate programs. The OAS pension is funded out of the general tax revenues of the Government of Canada, while the CPP is funded by contributions from workers and employers. You can receive both the OAS pension and the CPP retirement pension at the same time, but the amount you receive from each program is calculated separately.
The CPP retirement pension is based on how much you have contributed and how long you have been making contributions when you reach the age of 65. If you have contributed to the CPP, you will receive a monthly payment that is separate from your OAS pension. The CPP retirement pension is also taxable, unlike the OAS pension and other OAS benefits.
Interaction with Private Pensions
Private pensions, such as employer-sponsored pension plans and Registered Retirement Savings Plans (RRSPs), can also affect your OAS benefits. If you start receiving income from a private pension, your GIS amount may be reduced. However, income from a private pension does not affect your basic OAS pension amount.
It is important to consider how your private pension income will affect your OAS benefits when planning for retirement. You may want to consult with a financial advisor or use online tools and calculators to estimate your future income and benefits.
Planning for Retirement
Planning for retirement involves considering all sources of income, including the OAS pension and other OAS benefits, the CPP retirement pension, and private pensions. It also involves considering your expected living expenses in retirement, such as housing, food, healthcare, and leisure activities.
When planning for retirement, it is important to understand how the different parts of Canada's retirement income system work together. The OAS program, the CPP, and private pensions each provide a piece of the retirement income puzzle. By understanding how these pieces fit together, you can plan for a secure and comfortable retirement.
Estimating Your Retirement Income
One of the first steps in planning for retirement is to estimate your future income. This includes estimating your OAS pension and other OAS benefits, your CPP retirement pension, and your income from private pensions and savings. The Government of Canada provides online tools and calculators that can help you estimate your future benefits.
When estimating your retirement income, it is important to consider inflation and the cost of living. The cost of living tends to increase over time, which means that the purchasing power of your retirement income may decrease. To account for this, you may want to plan for a retirement income that is higher than your current income.
Planning for Living Expenses
Another important part of planning for retirement is to estimate your future living expenses. This includes housing costs, food costs, healthcare costs, and costs for leisure activities. You should also plan for unexpected expenses, such as home repairs or medical emergencies.
When planning for living expenses, it is important to consider your lifestyle and your goals for retirement. For example, if you plan to travel extensively in retirement, you will need to budget for travel expenses. If you plan to live in a retirement community, you will need to budget for the cost of that community.
Old Age Security (OAS) for Retirement Planning: Conclusion
The Old Age Security program is a key part of Canada's retirement income system. It provides a basic level of income in retirement and offers additional benefits to low-income seniors. Understanding the OAS program and how it interacts with other parts of the retirement income system can help you plan for a secure and comfortable retirement.
Planning for retirement involves considering all sources of income and all expected expenses. By taking the time to understand the OAS program and to estimate your future income and expenses, you can take control of your financial future and plan for the retirement you want.
