Canada funds retirement through three overlapping pillars. Almost every retirement plan is some blend of them, and the art of planning is deciding how much weight each one carries and when to turn each one on.

Pillar 1 — Government benefits. Old Age Security (OAS) and the Guaranteed Income Supplement (GIS) are paid from general tax revenue. You do not contribute to them directly through payroll; eligibility is based on age and years of residency in Canada, and GIS is income-tested.

Pillar 2 — CPP or QPP. The Canada Pension Plan (or the Quebec Pension Plan for those who work in Quebec) is a contributory, earnings-based public pension. What you receive is tied to how much and how long you contributed during your working years.

Pillar 3 — Private savings. Workplace pensions (defined benefit or defined contribution), group RRSPs, and your own registered and non-registered accounts — RRSP/RRIF, TFSA, FHSA, and taxable investments. This is the pillar you control most directly, and for most Canadians it is what closes the gap between government benefits and the lifestyle they want.

A useful rule of thumb: base CPP is designed to replace about a quarter of your eligible earnings (rising toward roughly a third under the enhancement), and OAS adds a flat residency-based amount on top. Together they commonly replace only 30–40% of a middle earner's income — so Pillar 3 usually does the heavy lifting.

Old Age Security (OAS) is a monthly benefit available from age 65 based on how long you have lived in Canada after age 18. A full pension requires 40 years of residency; with at least 10 years you receive a prorated amount (years ÷ 40). For the July–September 2026 quarter, the maximum OAS is about $751.97/month for ages 65–74 and about $827.17/month for ages 75 and over (OAS is 10% higher at 75+). These amounts are reviewed every quarter and rise with the Consumer Price Index.

You can defer OAS past 65 by up to five years. Each month of deferral adds 0.6% (7.2% per year), for a maximum increase of 36% at age 70. Deferral makes most sense if you are still working, expect a long life, or want to reduce clawback exposure in your late 60s.

OAS recovery tax (the clawback) reduces OAS when your net income is high. For the 2026 tax year, OAS is reduced by 15 cents for every dollar of net income above roughly $95,323, until it is fully eliminated. Most retirees never hit this threshold, but it is a real planning constraint for those with large RRIF withdrawals, pensions, or capital gains. See the dedicated OAS clawback guide.

Guaranteed Income Supplement (GIS) tops up OAS for lower-income seniors. It is non-taxable and strictly income-tested: the maximum for a single senior is about $1,123/month for the current quarter, reduced as other income rises and eliminated once income exceeds roughly $22,800. Because registered withdrawals count as income but TFSA withdrawals do not, withdrawal order matters enormously for anyone near GIS eligibility.

The Canada Pension Plan is an earnings-based pension you can start any month between ages 60 and 70. Your amount depends on your contributions and earnings over your career, with low-earning periods partially dropped out of the calculation.

Timing. The standard age is 65. Starting early reduces your pension by 0.6% per month (up to −36% at 60); delaying increases it by 0.7% per month (up to +42% at 70). For 2026 the maximum at 65 is $1,507.65/month, though the average new pension is far lower (roughly $800–$900) because few people contribute at the maximum for a full career. Always use your My Service Canada Account estimate, not the maximum, as your starting figure. The when-to-take-CPP guide covers the timing decision in depth.

The CPP enhancement. Since 2019 CPP has been growing. On top of the first earnings ceiling (the YMPE, $74,600 in 2026) there is now a second ceiling (the YAMPE, $85,000 in 2026) with an extra contribution rate. Over a full career under the enhanced rules, CPP is designed to replace about 33% of eligible earnings rather than 25%. Today's retirees see little of this; younger workers will see materially larger pensions.

Related CPP benefits. CPP also provides a disability pension, a survivor's pension, a children's benefit, a post-retirement benefit (if you keep working while collecting), and a one-time death benefit of $2,500. QPP mirrors CPP with its own administration and factor tables — confirm Quebec figures with Retraite Québec.

Workplace pensions come in two main forms. A defined benefit (DB) plan promises a formula- based pension for life (often based on years of service and salary) — the employer carries the investment risk. A defined contribution (DC) plan (or a group RRSP) builds a pot of money from contributions and returns — you carry the investment risk and decide how to draw it down. Knowing which you have, and whether it is indexed to inflation, changes your whole plan.

RRSP → RRIF. Registered Retirement Savings Plan contributions reduce taxable income now; growth is tax-deferred; withdrawals are fully taxable later. By the end of the year you turn 71 an RRSP must convert to a Registered Retirement Income Fund (RRIF) or annuity, after which a minimum percentage must be withdrawn each year and taxed as income.

TFSA. The Tax-Free Savings Account is funded with after-tax dollars; growth and withdrawals are completely tax-free and do not count toward the OAS clawback or GIS income test. Withdrawals restore contribution room the following calendar year.

FHSA. The First Home Savings Account combines an RRSP-style deduction with TFSA-style tax-free withdrawals for a qualifying first home ($8,000/year, $40,000 lifetime). It is not a retirement account per se, but it interacts with RRSP room and the Home Buyers' Plan and belongs in any complete picture of registered accounts.

Non-registered accounts. Ordinary taxable investment accounts have no contribution limits. Only realized capital gains (currently 50% included in income), interest, and dividends are taxed — so the effective tax rate on a non-registered withdrawal is usually far below the rate on an equal RRIF withdrawal. Compare the RRSP vs TFSA guide for where your next dollar should go.

Every pillar is filtered through the tax system, and retirement introduces credits most workers never used. In 2026 the federal basic personal amount (income you can earn before federal tax) is up to $16,452. From age 65 the age amount adds a further credit (up to about $9,208 in 2026, phased out as income rises past roughly $46,432). The pension income amount shelters the first $2,000 of eligible pension income (such as RRIF payments at 65+).

Pension income splitting lets you move up to 50% of eligible pension income to a lower-income spouse (Form T1032), which can cut a couple's combined tax and keep both spouses below the OAS and age-amount phase-out thresholds. Combined with TFSA use and careful withdrawal sequencing, it is one of the most powerful levers available to couples.

Provincial tax stacks on top of federal tax. Our tools model Ontario (including the surtax and Ontario Health Premium), Alberta, and British Columbia in full; Quebec is currently approximated with a clear flag because it uses QPP and the Quebec abatement.

The reason retirement planning is hard is that these pillars are not independent. A single decision ripples across all of them:

• A large RRIF withdrawal raises taxable income, which can trigger OAS clawback and erase the age amount in the same year.
• Delaying CPP and OAS produces larger, partly inflation-protected cheques for life, but means drawing down savings faster in your 60s.
• Drawing from a TFSA instead of a RRIF keeps taxable income (and clawback risk) down, but uses up the most tax-efficient account you own.
• For lower-income seniors, any registered withdrawal can reduce GIS by 50 cents on the dollar — effectively a very high marginal rate.

This is why the order you draw accounts down — your withdrawal sequence — can change lifetime tax and clawback by tens of thousands of dollars, and why a year-by-year cash-flow projection beats any single rule of thumb.

Consider Maya, 64, single, in Ontario, planning to retire at 65 with a $600,000 RRSP, a $120,000 TFSA, an estimated CPP of $1,100/month at 65, and full OAS. She wants about $55,000/year after tax.

• CPP ($13,200) and OAS (about $9,000) give her roughly $22,000 of mostly taxable income before she touches savings.
• She needs to fund the remaining ~$33,000 of spending from her portfolio. Pulling it all from the RRIF adds fully taxable income; blending in some TFSA keeps her well below the ~$95,000 clawback threshold and preserves the age amount.
• Because she is comfortably under the clawback line, her bigger question is longevity: at 65 her portfolio must potentially last 30+ years, so a Monte Carlo stress test matters more than shaving clawback she will not face.

Change one input — say she also has a $40,000/year DB pension — and the answer flips: now clawback is a live risk and TFSA-first or pension-splitting strategies move to the front. There is no universal “best” order; there is only the best order for your numbers.
