CPP and OAS Timing: How to Decide When to Start Your Canadian Government Benefits

By Karen Fenske, Fenske Financial Coaching & Planning

Few retirement decisions have a bigger long-term impact than when you choose to start your Canada Pension Plan (CPP) and Old Age Security (OAS) benefits. These are not just monthly cheques — they are lifetime income streams that will keep paying for the rest of your life, and the amount you receive depends heavily on when you choose to begin. The default age is 65, but you have flexibility on either side. CPP can begin as early as 60 or be delayed as late as 70. OAS can begin at 65 or be deferred up to age 70. The right choice for you depends on your health, your other income sources, your tax situation, and your goals.

In this guide, you will learn how CPP and OAS work, what changes when you take them early or delay them, the financial trade-offs involved, and how to evaluate the best timing for your own circumstances. The goal is not to find a single right answer, but to give you the clarity you need to make a confident choice.

How Does CPP Work and What Determines Your Payment?

The Canada Pension Plan is a contributory program — you and your employers (or you alone, if self-employed) have been paying into it throughout your working life. The amount you receive in retirement depends primarily on how much and for how long you contributed, and on the age at which you choose to start collecting. The standard age to begin CPP is 65, and Service Canada calculates your benefit based on your 40 highest-earning years, with provisions that allow you to drop out periods of low or no earnings such as time spent raising young children.

If you start CPP before age 65, your payment is reduced by 0.6 percent for each month you take it early — that adds up to a 36 percent reduction if you start at age 60. If you delay CPP past age 65, your payment increases by 0.7 percent for each month you wait, which is a 42 percent increase if you delay all the way to age 70. These adjustments are permanent and apply for the rest of your life.

How Does OAS Work and How Is It Different from CPP?

Old Age Security is a different kind of benefit. Unlike CPP, OAS is not based on contributions you have made — it is a residency-based pension funded out of general tax revenues. To qualify for full OAS at age 65, you generally need to have lived in Canada for at least 40 years as an adult. Partial OAS is available with at least 10 years of Canadian residency after age 18.

OAS can be deferred for up to 60 months past age 65, with payments increasing by 0.6 percent for each month of deferral. That means delaying OAS all the way to age 70 results in a 36 percent permanent increase. Unlike CPP, you cannot start OAS before age 65. OAS is also subject to a clawback, formally called the OAS Recovery Tax, which begins reducing your benefit once your net income passes a threshold — a key consideration for higher-income retirees.

What Are the Arguments for Taking CPP Early?

Despite the permanent reduction in monthly payment, taking CPP early can make sense in a number of situations. The decision is rarely just about math — it often involves health, lifestyle, and the rest of your financial picture.

Health considerations: If you have a shorter life expectancy due to health conditions, taking CPP earlier means you collect more benefits during the years you will actually use them.

Income needs in early retirement: If you retire before age 65 and need income to bridge the gap, starting CPP at 60 can reduce the pressure on your other savings.

Loss of contribution years: If you stop working before 65, the dropout provisions can only do so much. Sometimes starting earlier minimizes the impact of low-earning years on your benefit calculation.

Personal philosophy: Some retirees simply prefer guaranteed money in hand now over a larger payment in the future they may not live to enjoy.

What Are the Arguments for Delaying CPP and OAS?

Delaying CPP and OAS is increasingly recognized as one of the most powerful retirement planning tools available to Canadians. The increases for delaying are generous — a 42 percent permanent boost to CPP and 36 percent to OAS — and these are some of the only inflation-indexed, guaranteed-for-life income streams available.

Longevity protection: If you live well into your 80s or 90s, the delayed benefits dramatically increase your total lifetime income and reduce the risk of outliving your savings.

Higher lifetime income: Although you collect for fewer years, the larger payment can result in more total dollars received if you live past the breakeven age, typically in your mid-70s to early 80s.

Tax efficiency in early retirement: Delaying CPP and OAS means you can withdraw more from RRSPs in your 60s while in a lower tax bracket, before mandatory RRIF minimums begin at age 72.

Inflation protection: Both CPP and OAS are indexed to inflation, so the increase from delaying compounds over time as the cost of living rises.

Reduced reliance on investments: Higher guaranteed income from CPP and OAS means less dependence on market performance for your essential expenses.

Households underutilize the option to delay public pension benefits, despite evidence that delaying often results in higher expected lifetime income and improved longevity insurance. (Get the Most from the Canada and Quebec Pension Plans by Delaying Benefits, B Milligan, 2020)

How Does the OAS Clawback Affect Timing Decisions?

The OAS clawback, officially the OAS Recovery Tax, reduces or eliminates your OAS payments once your net income exceeds an annual threshold that changes yearly. For Canadians whose retirement income pushes them into the clawback zone, careful planning around the timing of RRSP and RRIF withdrawals, dividend income, and capital gains becomes essential. If you expect to be subject to the clawback, delaying OAS may actually allow you to draw down your RRSP first in your 60s — when your income is lower — and then collect a higher OAS payment later once your registered withdrawals are reduced.

This kind of coordinated planning is one of the most valuable aspects of working with a financial coach or planner. The interaction between OAS, CPP, RRSP withdrawals, pension splitting, and capital gains can be complex, but well-designed strategies can reduce or eliminate the clawback altogether and dramatically increase your after-tax retirement income.

How Should You Decide When to Start Your Benefits?

There is no single formula that works for everyone. The right timing depends on factors that are specific to your situation. The key is to consider all of them honestly rather than defaulting to age 65 because it is the standard.

Health and family longevity: Be realistic about your health and your family history. If most of your relatives have lived into their late 80s or 90s, delaying may be especially valuable.

Other income sources: If you have a generous workplace pension or substantial RRSP balances, you may not need CPP and OAS in your early 60s.

Spouse or partner planning: Couples can coordinate their start dates to balance income, optimize tax brackets, and provide longevity insurance for the surviving partner.

Cash flow needs: If delaying benefits would mean drawing down savings to a level that makes you uncomfortable, it may not be the right choice for you even if the math favours it.

Tax situation: Your marginal tax rate now versus later can make a significant difference in the net benefit of each timing option.

Why Personalized Coaching Matters for These Decisions

CPP and OAS timing is one of those decisions where a generic recommendation simply does not work. Two people of the same age with the same CPP entitlement can face very different optimal strategies depending on their health, their savings, their tax brackets, their spouse's situation, and their personal goals. Personalized financial coaching helps you walk through these variables honestly and arrive at a decision that fits your life rather than someone else's.

Because CPP and OAS timing decisions are essentially permanent — you cannot retroactively change them once you have started — getting this right matters enormously. Independent, unbiased guidance, with no products being sold to you, ensures the recommendation truly fits your circumstances rather than someone else's interests.
