OAS Facts You Need to Know before Retirement

Old Age Security (OAS) is a key retirement income program in Canada, but it’s often misunderstood. Many seniors end up losing money, facing clawbacks, or missing out on benefits simply because the details were never clearly explained. Here are some important OAS facts to know before you retire.

If you are a Canadian who is retiring or about to retire then be sure to read the information below. It could save you thousands of dollars over the years. There are many things the government does not tell you and these are facts that you should know.

OAS Is Based on Residency — Not Work History

Unlike CPP, OAS does not depend on your employment record. You earn OAS by living in Canada as an adult.

Why this matters:

• New immigrants may still qualify
• Stay‑at‑home parents qualify
• People with limited work history qualify

You Can Qualify With as Little as 10 Years in Canada

If you’ve lived in Canada for 10 years after age 18, you may receive a partial OAS pension.

OAS Amount Based on Years of Residency

Years in Canada	OAS Amount
10 years	25% of full OAS
20 years	50% of full OAS
30 years	75% of full OAS
40 years	100% of full OAS

🇨🇦 3. You Need 40 Years of Residency for the Full OAS

To receive the maximum monthly payment, you must have lived in Canada for 40 years between ages 18 and 65.

If you have fewer years, your OAS is prorated.

Time Spent in Certain Countries Can Count Toward OAS

Canada has social security agreements with many countries. If you lived or worked in one of them, those years may help you:

• Qualify for OAS
• Increase your partial pension
• Receive benefits even if you don’t meet the 10‑year rule

Examples of agreement countries: United States, United Kingdom, Italy, Germany, Australia, and many more.

You Can Delay OAS to Age 70 for a 36% Increase

Deferring OAS increases your payment by 0.6% per month, up to 36% at age 70.

OAS Payment Increase by Deferral Age

Start Age	Increase	Monthly OAS (example)
65	0%	$713
67	+14.4%	$816
70	+36%	$970

Deferring makes sense if:

• You’re still working
• You have high income at 65
• You want to avoid clawback
• You expect a long lifespan

OAS Is Taxable — and High Income Can Trigger the Clawback

The OAS Recovery Tax (clawback) applies when your net income exceeds the annual threshold.

Example Clawback Calculation

If the threshold is $90,000 and your income is $95,000:

$$(95,000-90,000)\times 0.15=750$$

You would repay $750 of your OAS.

The Claw back Is Based on Net Income, Not Taxable Income

This is one of the biggest surprises for seniors.

The following can push you into clawback territory:

• RRSP withdrawals
• Capital gains
• Dividends
• RRIF income
• Some benefits

Example: A $20,000 RRSP withdrawal could trigger clawback even if your taxable income is low.

OAS Is the Key to Unlocking GIS

Even a partial OAS can qualify you for the Guaranteed Income Supplement (GIS) — the most valuable benefit for low‑income seniors.

A senior with:

• Partial OAS
• Low income
• No RRSP withdrawals

…could receive $1,000+ per month in GIS.

You Can Receive OAS While Living Outside Canada

If you’ve lived in Canada for 20 years after age 18, you can collect OAS anywhere in the world.

Example: A senior who lived in Canada from age 25 to 55 (30 years) can retire in Mexico and still receive OAS.

Your Home Equity Does Not Affect OAS

OAS is not means‑tested based on assets.

You can own:

• A million‑dollar home
• A cottage
• A rental property

…and still receive full OAS.

OAS Facts That Will Revolutionize Your Retirement Income Strategy

OAS Increases Four Times a Year

OAS is indexed quarterly to inflation.

This makes it one of the most stable income sources for seniors.

Not Everyone Is Automatically Enrolled

If Service Canada doesn’t have enough information, you must apply manually.

Common reasons for missing auto‑enrollment:

• Name changes
• Missing tax returns
• Incomplete residency history
• Immigration records not linked

CPP Disability or Survivor Benefits Do Not Reduce OAS

These programs are separate. Receiving CPP‑D or CPP survivor benefits does not reduce your OAS.

OAS Facts Working After 65 Doesn’t Reduce OAS — Unless Your Income Is High

Employment itself doesn’t affect OAS. But higher income can trigger the clawback.

Example: A senior earning $45,000 pays no clawback. A senior earning $95,000 pays clawback.

OAS Facts You Can Ask Service Canada to Withhold Tax From Your OAS

If you expect to owe taxes or face clawback, you can request voluntary withholding.

Why this helps:

• Avoids surprise tax bills
• Helps manage clawback
• Keeps your cash flow predictable

Frequently Asked Questions

Is OAS guaranteed for life?

Yes — once approved, OAS continues for life and adjusts with inflation.

OAS Facts Can OAS be taken away?

Only if you fail to meet residency rules or your income is extremely high (clawback).

Should I defer OAS?

It depends on your income, health, and retirement plan. Deferring increases your payment by up to 36%.

Does OAS affect GIS?

Yes — GIS is based on your income after OAS is added.
