Old Age Security (OAS) & GIS: Everything You Need to Know

Did you know that over 6 million Canadians currently receive Old Age Security (OAS) payments? OAS is a vital source of income for seniors in Canada, ensuring a more stable retirement. In addition, the Guaranteed Income Supplement (GIS) provides extra financial support for those with lower incomes, helping to reduce financial stress in later years.

Understanding how these programs work is essential for your financial well-being. In this article, we’ll walk you through what OAS and GIS are, who qualifies, how to apply, and how much you could receive. If you’re approaching retirement or know someone who is, keep reading — this information is key to planning your financial future.

What is Old Age Security (OAS)?

Old Age Security (OAS) is a monthly payment from the Government of Canada for most people aged 65 and older. Unlike the Canada Pension Plan (CPP), you don’t need to have worked or contributed to receive OAS. If you’ve lived in Canada for at least 10 years after turning 18, you may be eligible.

OAS is adjusted quarterly based on the Consumer Price Index, so payments keep up with the cost of living. As of 2025, the maximum monthly payment for seniors aged 65 to 74 is about $615. For those 75 and older, the payment is slightly higher to help cover increasing expenses.

One thing to remember is that OAS payments count as taxable income. If your annual income is above a certain threshold (around $79,845 in 2025), your payments may be reduced through what’s called the “clawback” or OAS recovery tax.

Here’s a quick look at how OAS differs from other retirement benefits in Canada:

In the next section, we’ll cover exactly who is eligible for Old Age Security and what steps you need to take to ensure you receive your payments.

Eligibility for Old Age Security (OAS)

Understanding your eligibility for Old Age Security (OAS) is key to planning for your retirement income. Unlike other programs, OAS does not require you to have worked or contributed to the system, making it more accessible for many Canadians.

Here’s what you need to know:

• Age requirement: You must be at least 65 years old to qualify for OAS payments.
• Residency requirement: To be eligible, you must have lived in Canada for at least 10 years after turning 18.
• For newcomers or those who lived abroad: If you lived outside Canada, you may still qualify under certain agreements or if you’ve lived in Canada for a long enough period in total.

It’s important to note that if you have lived and worked in another country that has a social security agreement with Canada (like the U.S. or certain EU countries), those years abroad may count toward your residency requirement. This is helpful for many immigrants and Canadians who spent part of their career overseas.

Here’s a quick checklist to see if you meet the basic criteria for OAS:

If you’re unsure about your eligibility or have a unique situation (like working abroad or gaps in residency), it’s a good idea to speak with a financial advisor or call Service Canada directly. These experts can guide you through the process and help you avoid mistakes that might delay your payments.

In the next section, we’ll explain how to apply for OAS, including tips for a smooth application and what documents you’ll need to get started.

How to Apply for Old Age Security (OAS)

Applying for Old Age Security (OAS) might seem like a big step, but with the right information, it’s a smooth process. Here’s what you need to know to make sure your application goes through without any hiccups.

First things first: many Canadians are automatically enrolled in OAS when they turn 65. If you receive a letter from Service Canada confirming your automatic enrollment, there’s nothing more you need to do! But if you don’t get this letter or if there’s any uncertainty, you’ll need to apply yourself.

To start, you can apply online using your My Service Canada Account. This secure platform makes it easy to fill out your application and track the progress. If you prefer, you can also apply by mail using the paper application form available from Service Canada offices or their website.

Here’s a quick list of what you’ll typically need to include with your application:

• Proof of your date of birth (like a birth certificate or passport).
• Details about your residency in Canada since age 18.
• Information about your current and past addresses, especially if you’ve lived abroad.

It’s important to be honest and thorough when you fill out the forms. Missing information or errors can cause delays in getting your payments started. If you’re unsure about any part of the application, don’t hesitate to ask for help from Service Canada — they’re there to help you through the process.

Once your application is submitted, Service Canada will review it and let you know if you’re approved. This can take a few weeks, so be patient. While you wait, you can always log into your My Service Canada Account to check the status.

One last tip: even if you’re still working past 65, you can still receive OAS. It’s a great way to boost your income as you transition to retirement. If you’re thinking about delaying your application to get a larger payment (known as “deferring your OAS pension”), be sure to understand how that decision could affect your future payments.

In the next section, we’ll look at how much you could receive through OAS, including how payments are calculated and adjusted over time.

How Much You Could Receive

Knowing how much you could receive from Old Age Security (OAS) can help you plan your retirement more confidently. OAS payments are adjusted every three months to keep up with the cost of living, so you can count on some protection against inflation.

As of 2025, the maximum monthly OAS payment is around $615 for seniors aged 65 to 74. If you’re 75 or older, the amount goes up a bit to help cover higher living costs as you age. Keep in mind, not everyone will get the maximum. Your payment depends on how long you’ve lived in Canada after turning 18. If you’ve lived here for 40 years or more as an adult, you’ll likely get the full amount.

For those who’ve lived in Canada for less than 40 years, your payment will be a portion of the maximum, based on the number of years you’ve spent here. For example, if you’ve lived in Canada for 30 years since turning 18, you’d get 30/40ths of the maximum OAS payment.

Another important point is the “clawback” or recovery tax. If your income is over about $79,845 in 2025, you’ll see a reduction in your OAS payments. This clawback happens automatically at tax time, so it’s good to be aware of if you’re still earning income or receiving other pensions.

Here’s a quick tip: If you think your income will go over that threshold, consider speaking with a financial advisor about ways to reduce your taxable income and keep more of your OAS payments. Small changes in how you draw down savings can make a big difference.

For the latest payment amounts and updates, check the OAS payment rates page on the Government of Canada’s website. It’s always a good idea to stay up to date, especially since rates change every three months.

In the next section, we’ll talk about the Guaranteed Income Supplement (GIS). If your income is low, GIS can boost your monthly payments even further — and it’s not taxable. Let’s dive in!

What is the Guaranteed Income Supplement (GIS)?

The Guaranteed Income Supplement (GIS) is an extra monthly payment for low-income seniors who receive Old Age Security (OAS). If your income is below a certain threshold, GIS can make a big difference in covering your everyday expenses.

One of the best things about GIS is that it’s not considered taxable income. That means you don’t have to worry about paying taxes on this extra support, giving you a bit more peace of mind each month.

GIS was created to help make sure that seniors in Canada can live with dignity, even if their retirement savings or pensions are limited. It’s part of Canada’s commitment to supporting older adults who might be struggling to make ends meet.

To get GIS, you must already be approved for OAS. So, if you haven’t applied for OAS yet, that’s your first step. Once you’re receiving OAS, GIS can be added on top if you meet the income requirements.

Here’s a helpful tip: the amount of GIS you get depends on your income and whether you’re single or married. Every year, the government updates the income limits for GIS, so it’s a good idea to check these regularly. If you’re not sure where to start, the Government of Canada’s GIS page is the best place to find up-to-date numbers and information.

Another important thing to remember is that GIS isn’t permanent. You need to reapply for it each year when you file your taxes. Don’t worry — if you use the same address and your situation hasn’t changed much, the renewal process is usually simple and automatic. But it’s still good to double-check your paperwork so you don’t miss out on money you’re entitled to.

In the next section, we’ll dive deeper into who qualifies for GIS, what the income thresholds look like, and how to make sure you don’t miss out on this valuable benefit.

Eligibility for the Guaranteed Income Supplement (GIS)

Understanding whether you qualify for the Guaranteed Income Supplement (GIS) is crucial for planning your retirement income. GIS provides additional financial support to low-income seniors who are already receiving the Old Age Security (OAS) pension.

To be eligible for GIS, you must meet the following criteria:

• Age: You are 65 years of age or older.
• Residency: You reside in Canada and have lived in the country for at least 10 years since the age of 18.
• OAS Recipient: You are currently receiving the OAS pension.
• Income: Your annual income is below the specified thresholds, which vary depending on your marital status and whether your spouse or common-law partner receives OAS or GIS.

For instance, as of April to June 2025, if you are single, widowed, or divorced, your annual income must be less than $22,056 to qualify for GIS. If you have a spouse or common-law partner who receives the full OAS pension, your combined annual income must be less than $29,136. These thresholds are subject to change, so it’s advisable to consult the official Government of Canada GIS eligibility page for the most current information.

It’s important to note that certain situations may affect your eligibility:

• Sponsored Immigrants: If you are a sponsored immigrant who has lived in Canada for less than 10 years after age 18, you may not be eligible for GIS during the sponsorship period unless specific conditions are met, such as the sponsor’s death or bankruptcy.
• Non-Sponsored Immigrants: If you are a non-sponsored immigrant, you may be eligible for GIS based on the number of years you have resided in Canada after age 18. Additionally, if you have lived or worked in a country that has a social security agreement with Canada, you may be eligible for a partial benefit.

For a comprehensive understanding of your eligibility, including scenarios involving immigration status and residency history, refer to the detailed guidelines provided by the Government of Canada on the GIS eligibility page.
