What's the difference between CPP and OAS?

CPP (Canada Pension Plan) is contribution-based — you need at least one valid contribution, and your amount depends on how much and how long you contributed. OAS (Old Age Security) is residency-based, funded from general tax revenue — you need at least 10 years of Canadian residency after age 18, with 40 years for the full amount.

Can I take CPP before age 65?

Yes, as early as 60, but your payment is permanently reduced by 0.6% for every month before 65 (up to 36% less at 60). Waiting past 65 increases it by 0.7% per month, up to 42% more at 70.

CPP Is Contribution-Based, OAS Is Residency-Based

CPP eligibility and amount depend on your contribution history — the average payment at 65 is around $925/month, though the maximum is much higher for people who contributed the maximum for many years. OAS depends only on how long you've lived in Canada after 18, capped at $752/month (2026) for 40+ years of residency.
