OAS Canada: Your Comprehensive Guide to Old Age Security

In Canada, OAS Canada refers to the Old Age Security program, a fundamental component of the country's retirement income system. It provides a monthly pension benefit primarily aimed at seniors aged 65 and older who satisfy specific Canadian residency requirements. Understanding this program is crucial for retirement planning in Canada.

What is Old Age Security (OAS) in Canada?

The Old Age Security (OAS) pension is a monthly payment available to individuals aged 65 and over. It stands out as a universal program; eligibility isn't tied to your employment history. Whether you worked or not, you might qualify based on your time living in Canada after turning 18.

Importantly, the OAS Canada program is funded through the general revenues of the Government of Canada, meaning recipients are not required to make direct contributions to the program, unlike the Canada Pension Plan (CPP).

Who Qualifies for OAS Canada?

Eligibility for the OAS Canada pension hinges on specific criteria related to age and residency.

Age and Residency Requirements

To qualify for the Old Age Security pension, you must meet two primary conditions. Firstly, you must be 65 years of age or older. Secondly, you must have lived in Canada for a minimum of 10 years after turning 18. Your duration of residency in Canada directly impacts the potential benefit amount.

OAS Canada Benefits and Payments

The financial support provided through OAS Canada extends beyond the basic pension, incorporating additional supplements for those with lower incomes.

How Much Could You Receive?

The OAS pension is distributed as a monthly payment. The exact amount an individual receives is not fixed; it depends significantly on the number of years they have resided in Canada after the age of 18 and their annual income. Longer residency generally translates to a higher basic OAS pension, up to the maximum limit.

Additional Support: GIS and Allowances

Recognizing that the basic OAS pension may not be sufficient for everyone, the government offers supplementary benefits. If you are an OAS pensioner with a low income, you might also qualify for the Guaranteed Income Supplement (GIS). The GIS is a non-taxable monthly benefit added to your OAS payment. Furthermore, provisions exist for low-income individuals aged 60 to 64.

The Allowance may be available if you are the spouse or common-law partner of a GIS recipient. Similarly, the Allowance for the Survivor is available for individuals in this age group who are widowed or divorced and have low income.

Applying for OAS Canada

Accessing your OAS Canada benefits involves an application process, though in many cases, it may be initiated automatically by the government.

Automatic Enrolment

In many situations, Service Canada can automatically enroll individuals for the OAS pension. If sufficient information is available on file (often through the Canada Revenue Agency and other government sources), you may receive a letter informing you of your automatic enrolment the month after you turn 64. This simplifies the process considerably.

When to Apply Manually

However, automatic enrolment isn't guaranteed for everyone. If you do not receive a letter from Service Canada regarding the OAS pension by the month following your 64th birthday, it's likely you will need to submit an application. You should consult the detailed information on how to apply provided by Service Canada.

Managing Your OAS Benefits

Once you start receiving OAS Canada payments, you have several ways to manage your benefits and keep your information up-to-date, primarily through digital tools and direct contact with Service Canada.

Using My Service Canada Account (MSCA)

My Service Canada Account (MSCA) is a secure online portal offering extensive capabilities for managing your OAS and other government benefits. Through MSCA, you can view your application status, check payment details, print tax slips (T4A(OAS)/NR4-OAS), and update personal information such as banking details (direct deposit), address, phone number, and email.

You can also apply for related benefits like the GIS and Allowances, report income changes, manage voluntary tax deductions, delay your OAS pension start date, or even request to withdraw an application. Additionally, MSCA allows you to submit supporting documents electronically, request a reconsideration of a decision, or initiate an appeal to the Social Security Tribunal.

Contacting Service Canada

If you need assistance or prefer not to use online services, you can contact Service Canada regarding your OAS Canada pension through various channels.

These include online request forms (eServiceCanada for a callback), telephone (toll-free numbers with automated services available 24/7 and agent access during business hours), mail (for applications, updates, and document submission), and in-person visits to a Service Canada Centre (where ID verification is required for file access).

Service Canada provides average wait times for telephone inquiries on their website, which can help you plan your call.

OAS Canada and Your Taxes

Understanding the tax implications of your OAS Canada benefits is important for financial planning.

Understanding Your Tax Slips (T4A/NR4-OAS)

The OAS pension is considered taxable income. Each year, Service Canada issues tax slips detailing the amount of OAS benefits received. These are the T4A(OAS) slip for residents and the NR4-OAS slip for non-residents.

You can conveniently view, save, and print official copies of your tax slips for the current year and the past six years directly from your My Service Canada Account (MSCA).

You can also choose your preferred delivery method – either online access through MSCA or traditional paper copies sent by mail. Note that certain situations, like amended slips or specific payment conditions, might result in slips being mailed regardless of your preference.


In summary, OAS Canada represents a vital source of retirement income for eligible seniors. Key takeaways include its universal nature based on residency rather than work history, the eligibility threshold of age 65 with at least 10 years of Canadian residency after 18, and the availability of supplementary benefits like the GIS and Allowances for low-income individuals. While automatic enrolment simplifies the process for many, knowing how to apply manually and manage your benefits through My Service Canada Account or other contact methods is essential. Understanding the Old Age Security program allows Canadians to better prepare for their financial future in retirement.
