Same contributions, three accounts, three very different outcomes.
Put an RRSP, a TFSA, and a non-registered account under the exact same conditions — the same yearly contribution, earning the same return — and watch where each new dollar ends up. The finish lines are nowhere near each other, and the difference is entirely tax. Below you can see where it goes, including the make-or-break choice every RRSP holder faces: reinvest your refund, or spend it.
The scenario
After-tax value at retirement
The RRSP’s growing tax bill
How each account is taxed
TFSA
After-tax money in, nothing but tax-free growth after that.
RRSP
Pre-tax money in (you get a refund), but the CRA taxes every dollar coming out.
Non-registered
After-tax money in, and the growth is taxed along the way and on sale.
The RRSP refund: reinvest it or spend it?
An RRSP contribution is made with pre-tax dollars, so it triggers a refund — roughly your contribution times your working tax rate. A $7,000 contribution at a 28% bracket sends about $1,960 back to you. What you do with that refund decides whether the RRSP is brilliant or mediocre:
Reinvest it — put the refund to work (here, in a TFSA) and your true out-of-pocket cost matches the TFSA contributor’s. This is the RRSP working as intended, and it’s how the RRSP can match or beat a TFSA when your retirement tax rate is lower than your working rate.
Spend it — treat the refund as a windfall and the math collapses. You’ve effectively paid full freight for an account that still gets fully taxed on the way out. It’s the most common RRSP mistake, and the bars above show exactly how much it costs.
Every account here starts from zero, so this is a clean, apples-to-apples look at where your next dollar works hardest — no head start for anyone. The shaded area in the chart is the RRSP’s deferred tax, growing right alongside your savings.

Assumptions & sources. The non-registered figure assumes buy-and-hold growth taxed as a capital gain on sale (50% inclusion) at your retirement rate — its best case; dividend- or interest-heavy holdings would be taxed harder each year. RRSP withdrawals are taxed at the retirement bracket you select; the reinvested refund is assumed to grow tax-free in a TFSA. Tax rates are 2026 combined BC + federal marginal rates (TaxTips.ca); the default retirement income reflects the average total income of Canadians 65+ (Statistics Canada, Canadian Income Survey 2023). A simplified model that ignores OAS clawback, RRIF minimums, CPP, and contribution-room limits.
No single account wins for everyone
The bars above crown one winner, but in practice the smart move is usually a mix. The reason is simple: the TFSA is capped at a flat annual limit ($7,000 for 2026), so once you’ve filled it, every extra dollar has to live somewhere else. That’s where the RRSP and a non-registered account earn their place — the RRSP for the years your income (and tax rate) is high, and a taxable account for whatever spills past both registered limits.
A sensible default for many people: fill the TFSA first (tax-free is hard to beat and the room comes back when you withdraw), lean on the RRSP to knock down tax in your peak-earning years — reinvesting every refund — and let a non-registered account catch the overflow. The right blend hinges on your income today versus in retirement, which is exactly the conversation worth having before you commit.
Married or common-law? You have two sets of room. Filling only one partner’s TFSA and RRSP leaves half the household’s tax-sheltered space on the table. Coordinating both — and using tools like a spousal RRSP to even out your retirement incomes — can meaningfully cut the family’s lifetime tax bill. Plan the accounts together, as one household, rather than as two solo plans.
Watch the OAS clawback in retirement
Money held in an RRSP or a non-registered account produces taxable income in retirement — RRSP/RRIF withdrawals, plus interest, dividends and realized capital gains. That income feeds the OAS recovery tax (the “clawback”), which takes back 15¢ of your Old Age Security for every dollar of net income above an annual threshold (about $93k for 2025). A TFSA produces none of this — its withdrawals don’t count as income — which is part of why TFSA room is so valuable for managing income in retirement.
An RRSP can boost the Canada Child Benefit
If you have kids, an RRSP contribution can do double duty. The deduction lowers your family adjusted net income (AFNI), and the Canada Child Benefit is calculated on AFNI — so trimming it can increase your CCB, effectively a second refund stacked on top of the tax savings. A TFSA contribution, with no deduction, doesn’t change AFNI.
Which account is right for your dollars?
The right mix depends on your income now versus later, your room in each account, and what the money is for. That sequencing — RRSP vs TFSA vs taxable, and in what order — is exactly the kind of question we help business owners and professionals work through.
