When to Start CPP: 60, 65, or 70?

When to start the Canada Pension Plan is one of the most consequential and most reversible-seeming decisions in retirement, except that it is not reversible. Once you choose a start date, the adjustment to your monthly amount is permanent. Because CPP is a lifetime, inflation-indexed benefit, getting the timing right can be worth a great deal over a long retirement.

This article is for pre-retirees and retirees in Ottawa and across Ontario trying to decide between starting at 60, 65, or somewhere up to 70. The honest answer is that the best age is personal, but the factors that should drive it are clear and worth working through deliberately.

How the timing changes your payment

CPP has a standard start age of 65, with adjustments on either side.

• Start before 65, as early as 60, and the amount falls by about 0.6% for each month early, roughly 36% less if you start the day you turn 60.
• Start after 65, up to 70, and the amount rises by about 0.7% for each month you wait, roughly 42% more if you start at 70.

Start age	Approximate effect vs age 65
60	About 36% lower, permanently
65	Standard amount
70	About 42% higher, permanently

These adjustments are permanent and apply to an inflation-indexed benefit paid for life. For a fuller picture of how much you might receive in the first place, see how much CPP will I get, and for how CPP sits alongside OAS, see CPP vs OAS explained.

The case for waiting

Deferring CPP is, in effect, buying more guaranteed, inflation-protected lifetime income. Few other financial products offer that so cleanly. The enhancement from waiting is substantial, and because it is indexed and lasts for life, it directly protects against the risk of outliving your savings.

Waiting tends to make sense when you are in good health, expect typical or above-average longevity, have other income or savings to live on in the meantime, and value certainty in later life. For a retiree drawing down an RRSP in their early 60s, deferring CPP while spending registered savings can also serve a tax purpose, shrinking future RRIF minimums and reducing later clawback exposure. That interaction is explored in retirement withdrawal order in Canada.

The case for starting earlier

Starting CPP at or near 60 is not a mistake; it is a different set of trade-offs. It makes sense when you need the income to live on, when your health or family history suggests a shorter horizon, or when starting early lets you preserve investments or avoid drawing down savings too fast.

There is also a behavioural reality: some people simply prefer to receive what they have paid into for decades, and value income in their active early retirement years more than a larger amount at 80. That preference is legitimate. The key is to make it a considered choice rather than a default.

The break-even age, and its limits

A common way to frame the decision is the break-even age: the point at which the larger deferred payments catch up to the total you would have received by starting earlier. Depending on assumptions, this often lands somewhere in the late 70s to early 80s. Live past it, and deferring wins on total dollars; die before it, and starting early wins.

The break-even calculation is useful context, but it is an incomplete guide for three reasons. It treats the decision as a bet on your lifespan, when in fact the larger deferred benefit is best understood as insurance against living a long time and running short. It often ignores the tax differences between the two paths. And it leaves out peace of mind, which has genuine value. A retiree does not need to “win” the break-even bet for deferral to be the right call, because the real risk being managed is longevity, not mortality.

Put another way, insurance is not something you expect to profit from; it is protection against a costly outcome. A larger CPP cheque starting at 70 protects against the specific risk of living well into your 90s with savings running thin. Framed as insurance rather than as a wager on your lifespan, the deferral decision often looks more attractive than a simple break-even chart suggests, particularly for those in good health with other assets to draw on in the meantime.

Health, longevity, and your spouse

Your own health and family longevity are central. Someone with a serious health condition may reasonably start earlier, while someone with longevity in the family and good health may lean toward waiting.

For couples, the decision is a joint one. CPP timing interacts with survivor benefits and with the household’s overall income plan, so it is worth deciding together rather than in isolation. Balancing two sets of benefits and two tax returns is part of our retirement planning work, and coordinating income across a couple is discussed in financial planning for couples.

Taxes and the bigger picture

CPP is taxable income, so the start date also affects your tax situation. Starting it early while you still have employment or other income stacks taxable income and can raise your marginal rate or push you toward the OAS clawback threshold, covered in OAS clawback explained. Deferring CPP while drawing from registered accounts in lower-income years can smooth your lifetime tax bill.

A practical way to approach the decision:

• Confirm your estimated CPP at 60, 65, and 70 from your Service Canada statement.
• Subtract CPP from the income your portfolio and pension must otherwise provide.
• Consider your health, family longevity, and need for income now.
• Factor in the tax effect of adding CPP to your other income.
• For couples, decide in the context of both benefits and both tax returns.

CPP sharing and survivor benefits

For couples, CPP offers features beyond the simple timing choice. Spouses who are both at least 60 can apply to share their CPP retirement pensions, which can shift income from the higher earner to the lower earner and reduce the household’s overall tax. The benefit is modest and depends on your respective contribution histories, but it is a legitimate planning tool worth reviewing.

The survivor benefit is a more significant consideration. When one spouse dies, the survivor may receive a portion of the deceased’s CPP, subject to rules and an overall maximum that can limit how much a survivor already receiving their own CPP can collect. Because deferring CPP raises the base amount, the timing decision can also influence what a survivor eventually receives. These interactions reinforce that CPP timing is rarely a solo decision for a couple.

A decision worth revisiting

You do not have to settle the CPP question years in advance. Because you can start any time between 60 and 70, the decision can be reviewed as your circumstances evolve. A change in health, a shift in your other income, or an updated view of your longevity can all reasonably move the answer. What matters is that when you do decide, it reflects your current situation and your longer plan rather than a default or a rule of thumb picked up second-hand. Weighing it alongside your full income picture, as part of retirement planning, is how the decision earns its keep.

Next step

The question of when to start CPP rewards a deliberate answer. The adjustments are permanent, the benefit is a rare source of guaranteed inflation-protected income, and the right age depends on your health, your other income, and how much you value certainty later in life.
