For most Canadian retirees, income in retirement comes from three main government sources — CPP, OAS, and potentially GIS — plus whatever personal savings and workplace pensions you have built up. Understanding how these three pieces fit together is the single most useful thing you can do before you retire. Here is what a retiree actually gets.
The Three Pillars
| Benefit | What it is | 2026 maximum |
|---|---|---|
| CPP | Canada Pension Plan — based on your career contributions | Varies by contribution history |
| OAS | Old Age Security — near-universal, based on years of Canadian residency | $742.31/month (age 65-74) |
| GIS | Guaranteed Income Supplement — for low-income seniors, on top of OAS | $1,066.75/month (single) |
CPP: What You Actually Get Depends on You
Unlike OAS, CPP is not a flat rate — it is based on how much and how long you contributed during your working life. Contributions are calculated on earnings up to the Year's Maximum Pensionable Earnings, which is $74,600 for 2026, plus an additional tier (CPP2) on earnings up to $85,000. The more consistently you earned at or above these thresholds across your career, the higher your eventual CPP retirement pension. Use our salary calculator to see your current CPP contributions and get a sense of how your working years are building towards your eventual pension.
OAS: Residency-Based, Not Contribution-Based
OAS works completely differently from CPP. It is based on how many years you lived in Canada after age 18, not on your employment or contribution history. You need at least 10 years of Canadian residency after 18 to receive a partial OAS pension, and 40 years for the full pension. For 2026, the maximum monthly OAS at age 65 to 74 is $742.31, rising to $816.54 once you turn 75.
Remember that OAS is subject to the recovery tax (clawback) if your net income exceeds $92,817 in 2026 — so higher-income retirees may receive a reduced OAS, or none at all.
GIS: The Safety Net for Low-Income Seniors
GIS tops up OAS for seniors with little other income. For 2026, the maximum GIS for a single senior is $1,066.75 a month, phasing out entirely once your annual income (excluding OAS) reaches roughly $22,203. If you retire with a modest CPP pension and little in personal savings, GIS can make up a substantial part of your total monthly income.
What a Real Retiree Might Receive
Consider a single retiree with an average CPP pension, full OAS, and no other significant income. Their monthly income might look like:
- CPP: a mid-range monthly amount based on their contribution history
- OAS: up to $742.31 (age 65-74)
- GIS: a partial amount, since their CPP income reduces GIS on a sliding scale
By contrast, a retiree with a strong CPP pension and substantial RRSP or investment income might receive full CPP and OAS but no GIS at all, and could even face the OAS clawback if their total income is high enough. The combinations vary enormously, which is exactly why running your own numbers matters more than looking at generic averages.
Timing Matters
Both CPP and OAS can be taken earlier (from age 60 for CPP) or delayed (up to age 70 for both), with your monthly payment permanently reduced for early uptake or increased for delaying. This is one of the most consequential retirement decisions most Canadians make, and it interacts directly with GIS eligibility and the OAS clawback threshold, so it is worth planning carefully rather than defaulting to the earliest possible start date.
The Bottom Line
CPP, OAS, and GIS are designed to work together, but exactly how they combine depends entirely on your individual contribution history, residency, and other income. There is no single "average" retiree income that applies to everyone. Use our GIS calculator and salary calculator to build a clearer picture of where you are likely to land — ideally well before you actually retire, so you still have time to adjust your plan.
