The standard CPP start age is 65, but Canadians can start from age 60 to 70. Starting before 65 permanently reduces the monthly pension; delaying after 65 permanently increases it. The best choice depends on the entire retirement plan, not the CPP amount alone.
How CPP start age changes the pension
The Government of Canada states that CPP can start as early as age 60 or as late as age 70. Starting before age 65 reduces the pension by 0.6% for each month before 65, while delaying after 65 increases it by 0.7% for each month, up to age 70.
| Start age | Age adjustment versus 65 | Planning implication |
|---|---|---|
| 60 | Up to 36% lower | Cash flow begins sooner, but the lifetime monthly amount is permanently lower. |
| 65 | No age adjustment | Useful baseline for comparing alternatives. |
| 70 | Up to 42% higher | Higher indexed lifetime income, but requires funding the delay years from work or other assets. |
What a useful CPP calculator should compare
A retirement decision should compare more than the benefit at one age. A strong analysis also asks:
- How much must be withdrawn from RRSP/RRIF, TFSA or non-registered accounts while CPP is delayed?
- Does delaying CPP create lower-tax withdrawal opportunities before age 70?
- Will a higher CPP payment later increase OAS recovery tax or other income-tested effects?
- How does longevity change the value of receiving a larger indexed pension?
- For couples, how does each spouse’s CPP start age interact with household tax and survivor planning?
How the planner estimates and tests CPP
The planner can accept a CPP amount directly or estimate CPP from annual pensionable earnings history. It then compares CPP timing together with OAS timing and withdrawal strategies. This matters because a CPP decision that looks best in isolation can produce a different result after taxes and portfolio withdrawals are considered.
Compare your CPP start age
Use your own CPP estimate or earnings history, then compare retirement strategies at ages 60, 65 and 70.
Common CPP timing mistakes
- Choosing only by break-even age: break-even math ignores taxes, portfolio risk and the value of larger guaranteed income later.
- Assuming everyone should delay: cash needs, health, employment and other income can make earlier CPP reasonable.
- Ignoring investment withdrawals during the delay: delaying CPP may require more portfolio spending first.
- Using the maximum CPP amount: actual CPP depends on a contributor’s record and may be materially below the maximum.
