CPP at 60 Beats CPP at 70 When Your Health Makes 85 Unlikely
A 62-year-old with stage 3 kidney disease faces a pension arithmetic most actuarial tables don't address. The standard break-even model, delay CPP until 70, collect 42% more per month, recover the foregone early payments somewhere past age 82, assumes you will be around to collect. When your nephrologist is tracking glomerular filtration rates and talking about dialysis timelines, that assumption stops holding.
The math everyone quotes is correct for the population average. Taking CPP at age 60 instead of 65 cuts your monthly payment by 36%. Waiting until 70 increases it by 42% over the age 65 amount. For a typical retiree who makes it into their mid-80s, deferral wins. But chronic illness changes the question from "what maximizes lifetime value" to "what maximizes value during the years I'm most likely to have."
The real break-even isn't a date
The published break-even age for CPP deferral is usually quoted as 80 to 82, depending on the starting scenario. That's the point where someone who delayed starts receiving more cumulative dollars than someone who took it early. But the calculation treats every dollar as equal, which a retiree in declining health knows is false.
A dollar at 62 buys accessibility modifications to your home. It funds private physiotherapy before your mobility deteriorates further. It pays for the higher-quality hearing aids your provincial plan doesn't cover. A dollar at 83, if you're still around to spend it, buys less because your functional capacity to use it has narrowed. Your ability to travel, to eat at restaurants, to live independently all narrow. The standard models don't price that difference.
Add tax treatment and the picture shifts again. CPP is taxable income, but chronic illness often comes with significant medical expense tax credits. If you're claiming $18,000 annually in eligible medical costs, your effective tax rate on CPP income in your early 60s can be close to zero. That same pension income at 72, when your expenses have normalized and your RRIF withdrawals have started, gets taxed at your full marginal rate.
When longevity insurance doesn't insure you
Pension deferral is often described as longevity insurance, protection against outliving your savings. That framing is useful for healthy retirees. For someone with a chronic progressive illness, you are voluntarily under-insuring a risk (living past 85) that your specific medical profile suggests is low, in order to over-insure a risk (running out of money in your 60s and 70s) that is immediate.
A counterargument: medical advances happen. Type 2 diabetes that would have led to serious complications in the 1990s is now manageable with GLP-1 drugs. Someone diagnosed with congestive heart failure at 60 in 2026 may live well into their 80s. Taking CPP early because of a diagnosis locks you into a permanently reduced payment if you beat the odds.
Fair point. But the reverse risk is bigger. If you defer CPP to 70 based on optimistic longevity assumptions and die at 76, you collected higher payments for six years instead of lower payments for sixteen. The cumulative shortfall is real, and it hit during the years when you needed liquidity most.
OAS is a separate calculation
Old Age Security cannot start before 65, so there is no "early" option. The only question is whether to defer it past 65 for a 0.6% monthly increase, which compounds to 36% by age 70. For someone with health concerns, there is rarely a reason to delay. OAS has no survivor benefit, unlike CPP, and the deferral premium is smaller.
The decision compounds with spousal planning. A lower-earning spouse might be better served by the higher-earning partner taking CPP early, preserving RRSP and TFSA capital that can transfer tax-efficiently on death. OAS dies with you. Registered accounts don't.
Pension timing is usually treated as a problem of compound growth and rates of return. For most Canadians, that frame works. But it assumes you have the time to let compound growth work. Chronic illness is the condition where you don't.
