Retirement concepts
CPP and OAS timing concepts
CPP and OAS timing in Canada is a trade-off between starting income earlier and potentially receiving a larger monthly payment later. The right analysis depends on eligibility, health, work plans, spouse or partner income, taxes, Guaranteed Income Supplement interactions, other savings, and how much flexibility a household has.
Key takeaways
- CPP can start before or after age 65, with payment adjustments for timing.
- OAS generally starts at age 65 and can be deferred to age 70, subject to eligibility and official rules.
- Timing is not just a break-even calculation; taxes, cash flow, benefits, health, and longevity assumptions matter.
Official sources to check

What makes timing hard
Starting early can improve near-term cash flow. Starting later can increase monthly payments, but the value depends on how long someone lives, what other income they have, how taxes interact, and whether lower income affects benefits. Couples may also need to think about survivor income, pensions, and which household expenses are fixed.
