CPP Timing: Canada's Biggest Retirement Decision
No single financial decision has a more permanent, irreversible impact on Canadian retirement income than when you start CPP. Once elected, the monthly amount is locked for life. The difference between taking CPP at 60 versus 70 can exceed $1,000 per month — and over a 20-year retirement, that compounds to over $240,000 in lifetime income.
How the reduction and enhancement work
CPP adjustments are calculated to the exact month. Every month before 65 you take CPP, the amount is reduced by 0.6% — 36% total at age 60. Every month past 65 you defer, the amount increases by 0.7% — 42% total at age 70. These adjustments are permanent and applied to your base CPP entitlement.
The breakeven analysis explained
The breakeven age is the point where cumulative payments from the higher-amount option overtake cumulative payments from the lower. Deferring from 60 to 65 breaks even around age 74. Deferring from 65 to 70 breaks even around age 82. Statistics Canada's 2025 life tables show the average 65-year-old Canadian will live to 86 (women) or 83 (men) — making deferral mathematically advantageous for most people.
| Start Age | 2025 Max Monthly | Annual Income | Wins if you live past |
|---|---|---|---|
| Age 60 | ~$875/mo | ~$10,500/yr | Best only if life expectancy <74 |
| Age 65 | $1,365/mo | $16,380/yr | Best if life expectancy 74–82 |
| Age 70 | ~$1,938/mo | ~$23,256/yr | Best if life expectancy 82+ |
When taking CPP early makes sense
The math favours deferral for most — but not all. If you have a serious health condition that limits life expectancy, taking CPP early captures more total income. If you have no other income source and must cover expenses in your early 60s, starting CPP avoids drawing down investments at a worse time. And if you would invest the CPP payments at returns exceeding 5–6%, the opportunity cost of deferral narrows.
Coordinating with OAS and RRSP/RRIF
CPP doesn't exist in isolation. Taking CPP at 65 alongside OAS ($713/mo), RRIF withdrawals, and other income can push taxable income above $93,454 — the 2025 OAS clawback threshold. For high-income retirees, the TFSA becomes critical: TFSA withdrawals are not counted as income and don't trigger clawback.
