If you've run some numbers through the calculator and started thinking about actually doing this, the next question is usually "okay, but where does the money actually go?" For most Canadians just getting started, the answer is a TFSA — and it's worth understanding why, not just taking it on faith.
This trips a lot of beginners up. A TFSA (Tax-Free Savings Account) isn't a thing you buy, the way a stock or an ETF is. It's an account type — a wrapper you hold your investments inside. You open a TFSA, then you buy things inside it (an ETF like XEQT, for instance), and it's that wrapper that determines how the growth gets taxed. You can hold cash in a TFSA too, but using it purely as a high-interest savings account is leaving most of its value on the table.
Outside a registered account, every dividend or distribution you receive gets taxed the year you receive it, and so does any capital gain when you eventually sell. Inside a TFSA, none of that applies — the growth, the distributions, the eventual withdrawal, all of it is untouched by tax.
This matters more than it might sound like at first, especially for a DRIP-style strategy. Every distribution that gets reinvested compounds on its full value inside a TFSA, instead of losing a chunk to tax first. Over a long enough horizon, that difference compounds right along with the money — it's not a one-time saving, it's a saving that repeats every single distribution, for as long as the money stays invested.
A TFSA doesn't lock your money away until retirement. You can withdraw whenever you want, for any reason, with no penalty and no tax owed on the way out. If you pull money out, that contribution room comes back — just not until January 1 of the following year, so it's not instant, but it's not lost either.
That flexibility is a big part of why a TFSA makes sense as a starting point rather than, say, an RRSP. An RRSP is built specifically for retirement, and withdrawing from it early gets taxed as income — which makes it a worse fit for someone who's still building the habit of investing and might reasonably want access to some of that money before age 65.
The annual TFSA contribution limit for 2026 is $7,000, unchanged from the two years before it. Contribution room adds up automatically every year you're 18 or older and a Canadian resident — you don't need to have opened an account for the room to exist, and it carries forward indefinitely if you don't use it.
If you were 18 or older back in 2009, when the TFSA was introduced, and have never contributed a dollar, your cumulative room by 2026 is $109,000. That number has grown every year since 2009, with the annual limit ranging between $5,000 and $10,000 depending on the year (2015 had a one-year jump to $10,000 that was reversed the following year).
Anyone can check their own exact number for free, directly through the CRA — it's worth doing before your first contribution, since carrying it in your head is easy to get wrong. Here's how:
Worth being upfront: a TFSA isn't objectively "better" than an RRSP in every situation — it depends mostly on income. An RRSP contribution gets you a tax deduction today, which is worth more the higher your tax bracket is. For that reason, higher earners often come out ahead prioritizing RRSP contributions. But for most people early in their investing journey — lower income, earlier career, still building the habit — the practical order is TFSA first, RRSP once income climbs. And it's not really an either/or decision long-term: most Canadians end up using both.
Over-contributing is the big one — the CRA charges 1% per month on any amount over your available room, and it's tracked automatically, so it's not something that goes unnoticed. Withdrawing and recontributing in the same calendar year is the other common trip-up: the room doesn't come back until January 1 of the next year, so pulling money out and putting it back in a few months later can push you over your limit without you realizing it. And while it's rare, the CRA has gone after a small number of TFSA holders for very aggressive, frequent trading inside the account, on the grounds that it looked more like running a business than investing — a reason to keep the TFSA doing what it's good at (long-term, buy-and-hold investing) rather than active trading.
Open a TFSA, hold your investments inside it, and let compounding do the rest without tax taking a bite out of it along the way. That's the account this whole calculator assumes you're using — if you haven't opened one yet, that's the natural next step before picking your first investment.
