When Should You Take CPP? The Ontario Math Explained

The CPP Timing Decision That Could Be Worth Over $100,000

The decision of when to start your Canada Pension Plan benefits is one of the most debated topics in Canadian retirement planning. You can start as early as age 60 or as late as age 70, and the difference in monthly payments is dramatic. But the raw payment amounts only tell part of the story. For Ontario residents, the real answer depends on tax brackets, OAS interactions, other income sources, health, and your overall retirement planning strategy.

I work with families across London and Southwestern Ontario who wrestle with this question every year. This guide breaks down the actual math so you can make an informed decision rather than relying on rules of thumb.

The Basics: CPP at 60, 65, and 70

The standard age to begin CPP retirement benefits is 65. You can start as early as 60 or delay until 70, but your monthly payment is permanently adjusted based on when you begin.

Starting before 65: Your benefit is reduced by 0.6 percent for each month before age 65. That works out to 7.2 percent per year. If you start at age 60, which is 60 months early, your benefit is reduced by 36 percent.

Starting after 65: Your benefit is increased by 0.7 percent for each month after age 65. That works out to 8.4 percent per year. If you delay until age 70, which is 60 months late, your benefit is increased by 42 percent.

These adjustments are permanent. Once you start receiving CPP, your base payment amount is locked in. It still adjusts annually for inflation, but the early or late adjustment factor does not change.

2026 CPP Maximum Amounts

For 2026, the maximum CPP retirement pension at age 65 is approximately $1,364 per month, or $16,375 per year. Most Canadians do not receive the maximum. The average CPP payment at age 65 is closer to $830 per month.

Using the maximum as our baseline:

| Start Age | Adjustment | Annual Amount | |-----------|-----------|---------------| | 60 | -36% | $10,480 | | 65 | 0% | $16,375 | | 70 | +42% | $23,252 |

The difference between starting at 60 and waiting until 70 is striking: $873 per month versus $1,937 per month. That is more than double.

The Break-Even Analysis

The break-even question is straightforward: at what age does the person who delayed come out ahead in total cumulative payments versus the person who started early?

Age 60 vs. Age 65

Starting at 60, you receive $10,480 per year for five extra years before the age-65 starter begins. That is a $52,400 head start. But starting at 65, you receive $16,375 per year compared to $10,480, which means you gain $5,895 per year on the early starter.

Dividing the $52,400 head start by the $5,895 annual catch-up gives a break-even of approximately 8.9 years after age 65. That puts the break-even at roughly age 74.

If you live past 74, you would have been better off waiting until 65. If you do not reach 74, taking CPP at 60 was the right financial call.

Age 65 vs. Age 70

Starting at 65, you receive $16,375 per year for five years before the age-70 starter begins. That is an $81,875 head start. Starting at 70, you receive $23,252 per year compared to $16,375, gaining $6,877 per year.

Dividing $81,875 by $6,877 gives a break-even of approximately 11.9 years after age 65, or roughly 6.9 years after age 70. The break-even is approximately age 77.

If you live past 77, delaying to 70 was the right call. If you do not, starting at 65 was better.

The Real-World Adjustment

The simple break-even analysis above ignores two critical factors: the time value of money and taxes. If you take CPP early and invest the payments, the break-even age shifts later. If you delay CPP and draw down other savings to bridge the gap, the break-even analysis changes based on the return those savings would have earned. And taxes can shift the math significantly depending on what other income you have.

Ontario Tax Brackets and Your CPP Decision

CPP payments are taxable income. For London, Ontario residents, the tax paid on CPP depends on total income from all sources. This is where tax planning directly intersects with your CPP decision.

A lower-income retiree with only CPP and OAS (roughly $30,000 to $35,000 combined) pays a marginal rate of 20.05 percent. The tax impact of early versus late CPP is modest.

A higher-income retiree with a $50,000 pension plus $30,000 in RRIF withdrawals plus CPP is pushing $100,000. At this level, the marginal rate on CPP income is 31 to 34 percent. Taking CPP early at a lower amount might keep more of each dollar in the lower bracket.

The jump from 20.05 percent to 29.65 percent happens between roughly $52,000 and $90,000 of taxable income. If adding CPP pushes you across a bracket threshold, you need to account for the higher rate.

Impact on OAS and GIS

This is where CPP timing gets even more nuanced for Ontario retirees.

OAS Clawback

Old Age Security is clawed back when your net income exceeds approximately $90,997. For every dollar of net income above this threshold, you lose 15 cents of OAS. The full OAS payment is approximately $8,560 per year, and it is completely eliminated at a net income of roughly $148,065.

If delaying CPP to age 70 gives you an extra $6,877 per year in CPP income, and that extra income pushes you above the OAS clawback threshold, you are effectively losing 15 percent of that increase to OAS recovery tax on top of your marginal income tax rate. For a London, Ontario retiree in the 37.91 percent marginal bracket who also faces the OAS clawback, the combined marginal rate on that extra CPP income approaches 53 percent. At that rate, the advantage of a larger CPP payment shrinks considerably.

In this situation, taking CPP earlier at a smaller amount may actually result in more total after-tax income because you preserve more of your OAS.

GIS Considerations

The Guaranteed Income Supplement is available to low-income OAS recipients. GIS is clawed back at 50 percent (or 75 percent for certain income types) for every dollar of income above a low threshold. If you are eligible for or near GIS eligibility, CPP income directly reduces your GIS. Taking CPP early means lower CPP payments, which means higher GIS payments. In some cases, the GIS increase more than offsets the reduced CPP.

This is a particularly important consideration for single retirees in London, Ontario with limited savings. The interaction between CPP, OAS, and GIS can make early CPP the clearly better financial choice, even though the CPP payment itself is smaller.

Health and Longevity Considerations

The break-even analysis assumes you will live to a certain age. But nobody knows how long they will live, and personal health is the single most important factor in this decision.

If you are in poor health or have a family history of shorter lifespans, taking CPP at 60 is often the right call. The break-even age of 74 (versus starting at 65) means you need to live well into your mid-70s for delaying to pay off.

If you are in excellent health with a family history of longevity, delaying is powerful. Living to 85 or 90 means 10 to 15 extra years of the higher payment, often exceeding $100,000 in total additional benefits.

If you are uncertain, consider the insurance value of delaying. A larger CPP payment is an inflation-indexed annuity you cannot outlive.

Coordination with Other Income Sources

The CPP timing decision cannot be made in isolation. It interacts with every other piece of your retirement income picture.

CPP Sharing for Couples

For married or common-law couples in London, Ontario, CPP pension sharing is an often-overlooked strategy. If both spouses are age 60 or older and both receive CPP, they can allocate a portion of their CPP payments to each other. The amount you can share is based on the period of time you lived together during your contributory years.

The purpose of sharing is to equalize CPP income between spouses to reduce the overall household tax bill. If one spouse has a much larger CPP payment and is in a higher tax bracket, shifting some of that income to the lower-income spouse can save thousands of dollars per year in combined taxes.

CPP sharing should be coordinated with other income-splitting strategies, including pension income splitting and spousal RRSP planning, as part of a comprehensive retirement planning approach.

Bridge Strategies: Using Savings to Delay CPP

One of the most effective strategies for London, Ontario residents with adequate savings is to use RRSP or TFSA withdrawals to bridge the gap between retirement and age 70, allowing CPP to be delayed for the maximum increase.

A couple in London, Ontario who retires at 62 can draw from their RRSP to cover living expenses until 70. This allows CPP to grow by 8.4 percent per year, a guaranteed, inflation-indexed return that is almost impossible to replicate with any investment. Drawing down the RRSP before CPP and OAS begin also means withdrawals at lower marginal tax rates.

TFSA withdrawals are ideal for bridging because they are completely tax-free and do not affect government benefit calculations. A solid investment management strategy in the years leading up to retirement can ensure your bridge funds are properly positioned.

A Practical Example: A Couple in London, Ontario

Consider a couple in London, Ontario, both age 60. One spouse has a full CPP entitlement and a $400,000 RRSP. The other has a partial CPP ($9,800 per year at 65) and a $150,000 TFSA.

If both take CPP at 60, their combined CPP is $16,752 per year. If both delay to 70, combined CPP jumps to $37,168 per year. From 60 to 70, they bridge the gap using RRSP withdrawals (taxed at lower rates with no other income) and tax-free TFSA withdrawals.

By age 85, the delay strategy is ahead by more than $100,000 in cumulative after-tax income. The RRSP meltdown also reduced future RRIF minimums, keeping income lower and preserving more OAS.

When to Take CPP Early

Starting CPP at 60 makes sense when: you need the income to cover expenses, your health is poor, you are eligible for GIS (where the CPP-GIS interaction favours a smaller CPP), or you want to reduce reliance on your investment portfolio in early retirement.

When to Delay CPP

Delay to 70 when: you are in good health with a long life expectancy, you have other income sources to bridge the gap, you want to protect your spouse through a larger survivor benefit (an important component of estate planning for Ontario couples), or you want to maximize guaranteed, inflation-indexed income for life.

Getting Your CPP Decision Right

The CPP timing decision interacts with every other part of your retirement plan: your RRSP and TFSA strategy, your OAS, your tax bracket management, your life insurance needs, and your estate plan. Optimizing any one piece in isolation can make other pieces worse. The goal is to optimize the whole system.

For most London, Ontario residents, the right answer is not obvious without running the numbers specific to your situation. Factors like your exact CPP entitlement, your spouse's situation, your savings, your health, and your desired lifestyle all feed into the analysis.

If you are approaching 60 and have not yet modelled your CPP timing as part of a comprehensive retirement income plan, now is the time. The decisions you make in the years around retirement are often irreversible and have consequences that compound for decades.
