The Canada Pension Plan (CPP) gives you a 10-year window to claim your retirement benefit — from age 60 to age 70. Every month you shift that window in either direction changes your payment for life. Done well, smart timing adds 5-figure lifetime value. Done badly, it locks in a benefit that's 30%+ below what you could have had.
The mechanics
CPP has a "standard" claim age of 65, at which you receive your calculated benefit in full.
- Claim before 65: your benefit is reduced by 0.6% per month (7.2% per year) early. Claiming at 60 means a permanent 36% reduction.
- Claim after 65: your benefit increases by 0.7% per month (8.4% per year) delayed. Claiming at 70 means a permanent 42% increase.
The difference between claim-at-60 and claim-at-70 on the same person's work record is roughly $1,100/month versus $2,450/month — $16,000/year for life. Same contribution history. Different claim decision.
The break-even math
The naive question is: will I live long enough for the delay to pay off? Rough crossover points, ignoring investment returns:
- Claim-at-60 vs. claim-at-65: break-even around age 74.
- Claim-at-65 vs. claim-at-70: break-even around age 82.
- Claim-at-60 vs. claim-at-70: break-even around age 79.
The average 65-year-old Canadian today is expected to live into their mid-80s. Which means for people in average health, delaying past 65 generally wins on the math. Enhanced CPP (for people who contributed after 2019) makes delay slightly more valuable still.
When claiming at 60 is right
- Poor health or family history of early mortality.If you're unlikely to reach 75-80, the break-even never arrives. Claim the reduced benefit.
- You've stopped working and need the income. Between 60 and 65, drawing CPP is usually preferable to depleting RRSPs at market lows — especially if your retirement portfolio is in drawdown mode.
- You're no longer contributing.Once you stop working, your Additional Contribution Period ends. The incremental benefit of waiting shrinks (though it's not zero — the age-based adjustment still applies).
- Large RRSP/RRIF about to trigger OAS clawback. Drawing CPP earlier can let you drawdown RRSPs slower and avoid the OAS recovery tax on later income. Counterintuitive but real.
When delaying to 70 is right
- You're healthy and come from a long-lived family. Expected lifespan past 85 makes the 0.7%/month credit compound very favourably.
- You're still working at 65+ with good income. Delaying CPP lets your employment income fund those years while the CPP benefit grows. You also avoid stacking CPP on top of employment income for tax purposes.
- You have RRSP/other assets to bridge. If you can cover 65-70 from other sources, delaying CPP to 70 is roughly equivalent to buying an inflation-indexed, government-backed annuity at an excellent rate.
- You want to maximise survivor income. CPP survivor benefits are complex (see below) but larger CPP = larger survivor protection for your spouse.
Post-retirement benefit — the hidden CPP increase
Here's a wrinkle most people don't know: if you claim CPP between 60 and 65 and keep working, you're required to contribute (if under 65). Those contributions build a Post-Retirement Benefit (PRB) that adds a small amount to your monthly payment each year you contribute.
After 65 it becomes elective — you can choose to keep contributing or opt out. If you're still earning significantly, continuing to contribute for one or two more years can add meaningful long-term benefit.
The spouse angle
CPP survivor benefits are significantly less generous than Social Security's. In most cases the surviving spouse doesn't simply inherit the deceased's full benefit — there's a cap that accounts for the survivor's own CPP plus an age factor.
The practical effect for couples: the "delay for survivor" logic that's decisive in US Social Security is weaker in CPP. Delay decisions in Canada lean harder on personal longevity than on survivor-benefit preservation. This is an underappreciated cross-border difference.
OAS — the other clock
Old Age Security has a separate clock. Standard age is 65, you can delay to 70 for a 36% increase at 0.6%/month. Unlike CPP, OAS is residency-based, not contribution-based — so the claim age decision is cleaner. The same health + income logic applies.
The OAS clawback (Recovery Tax) kicks in at taxable income around $90,000 (2024 threshold; indexed yearly). If you're near or above that, delayed OAS might shift you into clawback territory once you claim. A coordinated claiming strategy matters.
The honest summary
For a healthy individual with other income sources: delay CPP to at least 65, and consider 70. The guaranteed 8.4%/year delayed credit beats most risk-adjusted alternatives.
For someone with health concerns, no bridge income, or a desire to reduce later-life RRSP/RRIF pressure: claiming earlier is defensible — especially if paired with a thoughtful OAS and RRSP drawdown sequence.
This is one of the highest-leverage decisions an advisor can help with. The fee for one consultation on CPP + OAS + RRSP drawdown sequencing often pays itself back several times over across a 20-30 year retirement.
