Question 1

When is the best age to claim CPP?

Accepted Answer

There is no universal best age. The math favors delaying past 65 if you live past roughly age 74; the math favors claiming at 60 if you expect a shorter life or need the income now. Other factors matter more than the actuarial breakeven: do you have other sources of income, are you still working (and at what marginal tax rate), is your spouse still working, do you need CPP to bridge to OAS at 65 or 70, and what is your family longevity? A retirement-income plan should look at all of these together. The breakeven calculator here gives you the actuarial-only answer.

Question 2

What is the CPP actuarial adjustment?

Accepted Answer

CPP applies a permanent monthly adjustment based on when you start collecting relative to age 65. Each month before 65 reduces your benefit by 0.6% (7.2% per year, max -36% at age 60). Each month after 65 increases your benefit by 0.7% (8.4% per year, max +42% at age 70). For a $1,200 base monthly benefit at 65: $768/month at 60, $1,200/month at 65, $1,704/month at 70. Once you start, the adjustment is locked in for life. CPP also indexes annually to CPI, which applies on top of the actuarial factor.

Question 3

Does CPP keep growing if I delay past 65?

Accepted Answer

Yes, in two ways. First, the actuarial factor adds 0.7% per month for every month you delay (up to age 70). Second, the benefit is still indexed to CPI each January even if you have not started. There is no benefit to delaying past age 70: the actuarial increase stops, so claiming at 70 versus 71 means you simply receive 12 fewer monthly payments at the same maximum rate. Most retirees who plan to delay should target a start date in the month after their 70th birthday to maximize lifetime value.

Question 4

Can I work and collect CPP at the same time?

Accepted Answer

Yes. There is no restriction on continuing to work while receiving CPP. If you are under 70 and still working, you (and your employer) keep contributing to CPP, which funds the Post-Retirement Benefit (PRB). The PRB is a small additional monthly amount that is added to your CPP each January and continues for life. At age 65 you can choose to opt out of CPP contributions while working by filing form CPT30. At age 70 contributions stop automatically.

Question 5

What is the child-rearing dropout provision?

Accepted Answer

The Child-Rearing Provision drops out months from your CPP calculation when you had low or zero earnings because you were the primary caregiver for a child under age 7. CPP calculates your retirement benefit using your earnings history, but it allows you to exclude periods of low earnings before kids; the drop-out raises your average pensionable earnings and therefore your benefit. The provision is automatic if you applied for Canada Child Benefit (or the previous Family Allowance) for the child. Same-sex parents are equally eligible.

Question 6

What is the difference between CPP and QPP?

Accepted Answer

CPP is administered by Service Canada for residents of all provinces except Quebec; QPP is administered by Retraite Quebec for Quebec residents. The contribution rates differ slightly (CPP is 5.95%, QPP is 6.3% in 2026), but the benefit math is identical: same actuarial adjustments, same lifetime maximums, same indexation. The two programs are fully reciprocal: if you contributed to both during your career, your years combine and you receive a single benefit from the program of the province where you reside when you apply.

Question 7

Will CPP survive my retirement?

Accepted Answer

Yes. The Office of the Chief Actuary publishes a CPP sustainability report every three years and consistently finds the program funded at least 75 years into the future at current contribution rates. The CPP Investment Board manages over $700 billion in assets that earn long-term real returns above what is needed to pay benefits. Unlike many foreign social-security programs, CPP is not a pure pay-as-you-go scheme; it is partially pre-funded, and contribution rates and benefits are set by federal-provincial agreement that requires a high threshold of consent to change.
