RRSP vs TFSA for Newcomers to Canada: Which Should You Open First?

If you arrived in Canada in the last few years, someone has probably already told you to "open an RRSP for the tax refund" — usually in February, usually in a hurry. But for many newcomer families in Ontario, the RRSP is not the right first account. The two accounts work in opposite ways, and the order you fund them in can change how much tax you pay for years. Here is how they actually work, in plain language, and a simple way to decide which one deserves your first dollar.

1. The core difference: when you pay the tax

An RRSP gives you a tax deduction now — contribute $5,000 and your taxable income drops by $5,000 — but every dollar you withdraw in retirement is taxed as income. A TFSA is the reverse: no deduction when you contribute, but all growth and withdrawals are completely tax-free. The general principle: an RRSP works best when you contribute in high-income years and withdraw in low-income years. A TFSA works well at any income, because you never pay tax on it again.

2. How newcomers earn contribution room — this trips everyone up

TFSA room only starts accumulating from the year you become a Canadian tax resident and are 18 or older. If you landed in 2024, you have room for 2024, 2025, and 2026 — not the full amount a lifelong Canadian has. A friend who was born here may have over $100,000 of room; you do not. Contributing based on someone else's room is how newcomers end up paying the CRA's 1% monthly over-contribution tax. RRSP room works differently: it is earned at 18% of your previous year's Canadian earned income, which means in your first year here you usually have zero RRSP room.

3. Why your first Canadian years often favour the TFSA

Many newcomers spend their first years in Canada earning less than they eventually will — recredentialing, restarting careers, or working survival jobs while a spouse studies. An RRSP deduction is worth less when your income (and tax bracket) is lower. Contributing to a TFSA now keeps your money growing tax-free while preserving your RRSP room for the higher-earning years ahead, when each deduction saves more tax.

4. When the RRSP becomes powerful

Once your household income rises — typically when your credentials land or you move into your field — the RRSP deduction starts working hard. Contributions made in a higher tax bracket generate larger refunds, which many families redirect toward debt or their children's RESP. RRSPs also unlock the Home Buyers' Plan, which lets eligible first-time buyers borrow from their own RRSP toward a down payment. If buying a first home is the goal, it is also worth asking about the FHSA, which combines an RRSP-style deduction with TFSA-style tax-free withdrawal for a first home.

5. It is rarely either/or forever

Most established families in Ontario eventually use both accounts — and often an FHSA or RESP as well. The real question is sequencing: which account gets funded first this year, given your income, your goals, and your debt. That answer changes as your situation changes, which is why a written plan beats a rule of thumb.
