CPP vs OAS: What's the Difference?

Most Canadians approaching retirement know they'll receive "government pension money" — but CPP and OAS are two very different programs, funded differently, earned differently, and subject to different rules. Confusing them can lead to real planning mistakes.

Here's the clearest breakdown you'll find.

The one-sentence version of each

CPP (Canada Pension Plan) is a pension you earned by working and contributing. The more you contributed over your career, the more you receive. Think of it as a forced savings plan that pays you back in retirement.

OAS (Old Age Security) is a universal benefit funded by general tax revenue. It has nothing to do with whether you worked. It's paid to Canadians who meet the age and residency requirements — full stop.

How CPP works

CPP is funded by mandatory contributions from workers and their employers. Every time you received a paycheque, a percentage went to CPP. Self-employed Canadians pay both the employee and employer share.

Your CPP retirement benefit is calculated based on how much you contributed and for how long — specifically, your average earnings over your contributory years, adjusted for periods of low income, child-rearing, and disability.

The standard age to begin CPP is 65. You can start as early as 60 (with a permanent reduction) or as late as 70 (with a permanent increase). The decision of when to take CPP is one of the most significant retirement income choices a Canadian makes — there's a separate guide on this site dedicated entirely to it.

Government benefit figures on this page reflect 2026 amounts and are updated annually. Verify current amounts at Canada.ca or Service Canada before making any decisions.

Maximum CPP retirement benefit at age 65 (2026): approximately $1,364/month for someone who contributed the maximum for 39+ years. Most Canadians receive significantly less — the average payment in 2025 was closer to $815/month.

To qualify for CPP, you must have made at least one valid contribution during your working life. There is no minimum residency requirement.

How OAS works

OAS is not connected to your employment record at all. It's funded by general tax revenue and paid to eligible Canadians based on age and years of residency in Canada after age 18.

To receive the full OAS pension, you need 40 years of Canadian residency after age 18. If you have between 10 and 39 years, you receive a partial pension (1/40th of the full amount for each year of residency). If you have fewer than 10 years of Canadian residency, you don't qualify — though international social security agreements can sometimes help.

OAS begins at age 65 by default. Like CPP, you can defer it up to age 70 in exchange for a permanently higher monthly amount — a 0.6% increase for each month you delay past 65, up to 36% more at age 70.

Maximum OAS pension at age 65 (2026): approximately $727/month for Canadians with 40+ years of residency. Those 75 and older receive an automatic 10% increase.

Unlike CPP, OAS is income-tested at the high end: if your net income exceeds a threshold (approximately $90,997 in 2026), you must repay part of your OAS through what's commonly called the "OAS clawback" (formally the OAS Recovery Tax). The full OAS is clawed back at incomes above approximately $148,000.

Side-by-side comparison

Can you collect both CPP and OAS?

Yes — and most Canadian retirees do. They're entirely separate programs and there's no reduction to one because of the other. If you qualify for both, you receive both.

The combined maximum for someone receiving full CPP and full OAS at age 65 in 2026 is approximately $2,091/month — before tax. That figure drops significantly for most Canadians, since average CPP payments are well below the maximum.

What if you never worked in Canada?

If you never contributed to CPP — because you didn't work, or worked entirely outside Canada — you won't receive a CPP retirement benefit. However, you may still qualify for OAS if you've lived in Canada long enough. Long-time residents who qualify for OAS but have low income may also qualify for the Guaranteed Income Supplement (GIS), a separate benefit for lower-income OAS recipients.

What if you worked in another country?

Canada has social security agreements with dozens of countries that allow contribution periods in another country to count toward eligibility in Canada. This applies to both CPP and OAS in different ways. If you've worked internationally, it's worth contacting Service Canada to understand how your foreign contribution history interacts with Canadian benefits.
