What is the main difference between CPP and OAS?

CPP (Canada Pension Plan) is a contributory pension based on your employment history and payroll contributions — the more you earned and contributed, the higher your CPP. OAS (Old Age Security) is a universal benefit based on how long you have lived in Canada, funded by general tax revenue. You do not need to have worked or contributed to receive OAS.

Can I receive both CPP and OAS at the same time?

Yes. Most Canadian retirees receive both CPP and OAS. They are paid on the same monthly schedule (the third-to-last business day of each month) and are often deposited together as a single direct deposit. The two programs are completely separate and do not affect each other's amounts.

At what age do CPP and OAS start?

You can start CPP as early as age 60 (with a permanent reduction) or as late as age 70 (with a permanent increase of up to 42%). OAS can only start at age 65 at the earliest, and can be deferred to age 70 for a maximum 36% increase. Both programs have no upper age limit once started.

Is CPP or OAS taxable income?

Both CPP and OAS are fully taxable as income in the year received. OAS is also subject to a recovery tax (clawback) if your net income exceeds $90,997 in 2026 — you repay 15 cents for every dollar over the threshold. CPP has no separate recovery tax but is included in your taxable income like any other pension.

CPP vs OAS 2026: Understanding the Difference Between the Two Pensions

CPP and OAS are both monthly government pensions paid to Canadian retirees, but they work very differently. CPP is earned through work contributions; OAS is earned through residency. Most Canadians receive both, but the eligibility rules, amounts, and timing decisions are separate for each.

What Is CPP?

The Canada Pension Plan is a mandatory public insurance program funded by payroll contributions from employees, employers, and the self-employed. Throughout your working life, a percentage of your earnings (up to the Year’s Maximum Pensionable Earnings, or YMPE) is contributed to the CPP fund. In 2026, the employee contribution rate is 5.95% of earnings between $3,500 and $71,300 — up to $4,034.10/year. Employers match this amount. Self-employed Canadians pay both shares (11.9%).

The pension you receive is calculated based on:

How much you contributed (your earnings relative to the YMPE ceiling)
How long you contributed (typically ages 18–65)
When you start receiving CPP (earlier = reduced; later = increased)

CPP has nothing to do with where you lived — it is purely about what you contributed through work.

What Is OAS?

Old Age Security is a monthly pension paid to Canadians aged 65 and over, funded from general government revenue (not a separate fund). You do not need to have worked or contributed to receive OAS. Instead, eligibility is based on:

Legal residency: You must be a Canadian citizen or legal resident (or have been one when you left Canada)
Years of residence: 10 years in Canada after age 18 for the minimum benefit; 40 years for the full OAS pension

If you lived in Canada for at least 10 but fewer than 40 years after age 18, you receive a partial OAS pension equal to 1/40 of the full pension for each complete year of residency.

Example: A 65-year-old who lived in Canada for 30 years after age 18 would receive 30/40 = 75% of the full OAS pension, or approximately $545.75/month in 2026.

CPP and OAS: Deferral Comparison

Both programs allow you to delay your start date past 65 in exchange for higher monthly payments. The rules differ slightly:

	CPP	OAS
Earliest start	Age 60	Age 65
Standard start	Age 65	Age 65
Latest start	Age 70	Age 70
Reduction for early start	0.6%/month (max 36% at age 60)	Not available
Increase for late start	0.7%/month (max 42% at age 70)	0.6%/month (max 36% at age 70)

CPP early start example: Taking CPP at age 60 instead of 65 results in a permanent 36% reduction. On a $1,433 maximum, that is $917/month instead of $1,433 — a difference of $516/month for life.

OAS deferral example: Delaying OAS from 65 to 70 increases $727.67/month to approximately $989.23/month (a 36% boost). This may be worthwhile if you are still working at 65 and do not need the income yet.

Which One Is Reduced If You Earn Too Much?

OAS only is subject to the recovery tax (commonly called the “clawback”). If your net income exceeds $90,997 in 2026, you must repay 15 cents for every dollar above this threshold. OAS is completely eliminated at approximately $148,451 of net income for those 65–74.

CPP has no clawback. No matter how much other income you have, your CPP is never reduced by Service Canada for being too wealthy. It is simply added to your taxable income.

Do CPP and OAS Affect Each Other?

No. CPP and OAS are entirely independent programs:

Receiving CPP does not reduce your OAS, and vice versa
Deferring one does not require deferring the other
You can start CPP at 60 and still receive full OAS at 65 (if eligible)
Your CPP amount has no effect on GIS calculations, but your combined income (including CPP and OAS) does affect GIS eligibility

Can Non-Residents Receive CPP and OAS?

CPP: Yes. If you contributed to CPP while working in Canada, you can receive CPP payments anywhere in the world. The payments may be subject to a withholding tax, reduced by a tax treaty if one exists between Canada and your country of residence.

OAS: Yes, if you meet the residency requirement (40 years for the full pension, with reduced pensions for 10–39 years). Canada has social security agreements with many countries that may allow years of foreign residency to count toward OAS eligibility. Non-resident OAS recipients are subject to a 25% withholding tax, reduced to 15% in treaty countries (including the US and UK).

CPP and OAS in Your Overall Retirement Income

For most Canadians, CPP and OAS together replace only a portion of pre-retirement income. A retiree at 65 receiving average CPP ($808/month) plus full OAS ($727.67/month) would have $1,535.67/month — about $18,428/year in government pension income. That is well below the $27,000–$40,000 many financial planners suggest for a modest retirement.

Additional income sources to consider:

RRSP/RRIF withdrawals — your private retirement savings
TFSA withdrawals — tax-free and do not affect OAS clawback
Workplace pension (Defined Benefit or Defined Contribution)
Investment income (dividends, capital gains, rental income)
