For most Canadians, the Canada Pension Plan (CPP) and Old Age Security (OAS) are the two cornerstones of government-supported retirement income. Yet according to a 2023 survey by the Canadian Institute of Actuaries, fewer than half of Canadians feel confident they understand how these programs work – or when it makes sense to start collecting them.

This guide breaks down exactly what CPP and OAS are, how they’re calculated, when you can access them, and how they might fit within a broader retirement income picture. No jargon. No guesswork. Just clear, factual information.

TL;DR – Key Takeaways

• CPP is based on your lifetime contributions; OAS is based primarily on age and residency.
• You can start CPP as early as age 60 or delay until age 70 – timing significantly affects your monthly amount.
• OAS begins at age 65 (or 70 if deferred), and high earners may face an OAS Recovery Tax (clawback).
• CPP and OAS alone are unlikely to fully replace your pre-retirement income – most Canadians rely on additional savings vehicles.
• Tools like the RRSP and TFSA are commonly used alongside government benefits to help build retirement income.

What Is the Canada Pension Plan (CPP)?

The Canada Pension Plan (CPP) is a mandatory, contributory public pension program administered by the federal government. Nearly every employed Canadian outside of Quebec (which has its own QPP) contributes to CPP through payroll deductions throughout their working life.

The amount you eventually receive depends on:

• How long you contributed
• How much you earned (and contributed) each year
• The age at which you begin collecting

As of 2024, the maximum monthly CPP retirement pension for someone starting at age 65 was $1,364.60, according to Employment and Social Development Canada. However, the average monthly payment was considerably lower – approximately $831.92 – because most Canadians don’t contribute at the maximum level throughout their full careers.

Note: CPP benefits are taxable income. You will receive a T4A(P) slip each year showing the amount you received.

What Is Old Age Security (OAS)?

Old Age Security (OAS) is a monthly federal payment available to Canadians aged 65 and older. Unlike CPP, it is not based on your work history or contributions. Eligibility is primarily tied to:

• Being 65 years of age or older
• Being a Canadian citizen or legal resident
• Having lived in Canada for at least 10 years after turning 18 (for those living in Canada)
• Or having lived in Canada for at least 20 years after turning 18 (for those living outside Canada)

As of Q1 2025, the maximum monthly OAS payment for Canadians aged 65–74 was $727.67, and for those aged 75 and over, it was $800.44, reflecting the 10% increase introduced in 2022 for seniors 75+.

What Is the Guaranteed Income Supplement (GIS)?

The Guaranteed Income Supplement (GIS) is an additional, non-taxable monthly benefit for OAS recipients with low income. For 2025, eligibility begins for single seniors with an annual income below approximately $21,624 (excluding OAS). The maximum monthly GIS for a single person was approximately $1,086.88.

The GIS is automatically assessed when you apply for OAS – no separate application is required.

CPP vs. OAS: Key Differences at a Glance

When Should You Start Collecting CPP?

This is one of the most common retirement questions Canadians ask – and the answer depends on individual circumstances.

Here is how the timing affects your CPP payment:

• Before age 65: Your payment is reduced by 0.6% for each month you collect early. Starting at 60 means a 36% permanent reduction.
• At age 65: You receive your standard calculated benefit.
• After age 65: Your payment increases by 0.7% for each month you delay. Waiting until 70 results in a 42% permanent increase.

Illustrative Example (For Educational Purposes Only)

Suppose a hypothetical Canadian retiree’s calculated CPP benefit at age 65 is $900/month:

These figures are illustrative only. Actual CPP amounts vary based on individual contribution history.

Generally speaking, delaying CPP may benefit those who:

• Have other sources of income in their early retirement years
• Are in good health and expect to live longer
• Want to maximize their lifetime income

Starting early may be more appropriate for those who:

• Need income immediately upon stopping work
• Have health concerns that may affect longevity
• Have minimal other savings or income sources

Consulting a qualified financial professional is always worthwhile before making this decision.

The OAS Clawback: What High-Income Retirees Should Understand

The OAS Recovery Tax (commonly called the clawback) is an important concept for higher-income retirees.

If your net world income for 2025 exceeds $90,997, you must repay a portion of your OAS at a rate of $0.15 for every dollar above that threshold. This repayment is spread across the following year’s monthly OAS payments.

For example (illustrative only):

• Net income of $100,000 → exceeds threshold by ~$9,003 → estimated clawback of ~$1,350/year
• Net income above approximately $148,000 → OAS may be fully clawed back

Strategies some Canadians explore with their advisors to help manage income in retirement include income-splitting with a spouse, using a Tax-Free Savings Account (TFSA) (whose withdrawals do not count as taxable income), and understanding how capital gains tax works in Canada.

These are general educational points only. Tax and income planning should always be discussed with a qualified tax or financial professional.

How Much Retirement Income Can CPP and OAS Provide?

It is important to have realistic expectations about what government benefits alone can provide.

Combining the average CPP (~$831/month) and maximum OAS (~$727/month) gives approximately $1,558/month, or roughly $18,700/year.

According to Statistics Canada, the median after-tax income for Canadian seniors in 2022 was approximately $32,000/year for individuals and $62,000 for couples. This suggests a significant gap between government benefits and the income many Canadians are accustomed to.

This gap is commonly addressed through:

• RRSP / RRIF: A Registered Retirement Savings Plan (RRSP) allows tax-deferred savings growth, which can be converted into a Registered Retirement Income Fund (RRIF) to generate income in retirement.
• TFSA: Withdrawals from a TFSA are tax-free and do not affect OAS or GIS eligibility – making it a potentially useful tool for managing retirement income.
• Non-registered investments: Understanding registered and non-registered accounts can help Canadians make more informed decisions about where their savings are held and how they are taxed.
• Workplace pensions: Defined benefit or defined contribution plans from employers.
• Personal savings and investments

How to Apply for CPP and OAS

Both programs require an application – they do not start automatically.

CPP Application:

• Apply through My Service Canada Account online, by mail, or in person
• Apply at least 6 months before you want payments to begin
• You will need your Social Insurance Number (SIN) and banking information

OAS Application:

• Some Canadians are automatically enrolled and receive a notification letter at age 64
• If not automatically enrolled, apply through My Service Canada Account
• Apply up to 12 months before you want payments to begin

Illustrative Scenario: Planning Retirement Income Around CPP and OAS

The following is a hypothetical, illustrative scenario for educational purposes only. It does not represent real individuals or constitute financial advice.

Meet “Diane” – a hypothetical 58-year-old small business owner in Ontario.

Diane has been self-employed for 20 years and has consistently made CPP contributions (both the employee and employer portions, as required for self-employed Canadians). She estimates her CPP at age 65 to be approximately $980/month based on her Service Canada statement.

She plans to retire at 63 and is wondering whether to start CPP early or wait.

The challenge: Starting CPP at 63 would reduce her payment by roughly 14.4% – bringing it to approximately $839/month. However, she has two years of bridge income to fund (ages 63–65) before OAS begins.

What she explores with a qualified advisor:

• Using TFSA withdrawals (tax-free) to bridge income from 63 to 65 without affecting future OAS
• Delaying CPP to 65 to preserve the full benefit amount
• Converting her RRSP to a RRIF at age 71 as required by CRA rules
• Understanding whether her business sale proceeds could trigger OAS clawback concerns

The educational takeaway: CPP and OAS timing decisions can interact with other income sources in meaningful ways. Understanding each piece – and how they connect – may help Canadians make more informed decisions before they retire.

Common Mistakes Canadians Make With CPP and OAS

Being aware of common misconceptions can help you ask better questions and make more informed choices:

1. Assuming CPP and OAS are enough – For many Canadians, government benefits replace only 30–40% of pre-retirement income. Additional savings are typically needed.
2. Not checking your CPP Statement of Contributions – Your actual benefit depends on your real contribution record. Review it periodically through My Service Canada Account.
3. Forgetting that both benefits are taxable – CPP and OAS are included in your taxable income each year. Tax planning matters in retirement.
4. Not applying on time – Late applications can delay payments. OAS back-payments are limited to a maximum of 11 months.
5. Overlooking the OAS clawback – If your retirement income is expected to be high, this is worth understanding in advance.
6. Ignoring survivor and disability CPP benefits – CPP also offers a survivor’s pension, a children’s benefit, and a disability benefit for those who qualify.

Conclusion

The Canada Pension Plan and Old Age Security are important foundations of retirement income for Canadians – but for most people, they are unlikely to cover all retirement expenses on their own.

Understanding how CPP is calculated, when to start collecting, how the OAS clawback works, and how these benefits interact with your personal savings can help you approach retirement with greater clarity.

Combining government benefits with personal savings tools – such as an RRSP, a Tax-Free Savings Account (TFSA), or other registered and non-registered investment accounts – is a path many Canadians explore as part of their long-term financial planning.
