Best Broker for a TFSA in Canada 2026: Wealthsimple vs Questrade vs Qtrade vs Interactive Brokers
Most "best TFSA broker" articles compare commissions. That comparison stopped being useful the moment Wealthsimple, Questrade, Qtrade and National Bank Direct Brokerage all landed at $0 on stocks and ETFs.
The costs that still differ inside a TFSA specifically are these three, and none of them appear in a commission table:
- What you pay to convert CAD to USD, since most Canadians hold at least some US exposure.
- Whether the broker lets you hold US dollars inside a TFSA at all — some auto-convert every USD balance back to CAD, which means you pay the FX spread on every dividend.
- Whether you can buy fractional shares, which matters enormously when your annual room is $7,000 and you're contributing $200 at a time.
Here's how the main options actually compare on those.
The short answer
| If you… | Choose |
|---|---|
| Are starting out, contributing small amounts monthly | Wealthsimple |
| Hold meaningful US-listed positions and want USD inside the TFSA | Questrade or Interactive Brokers |
| Want strong research and service without a bank platform | Qtrade |
| Want the lowest FX cost, period, and can handle complexity | Interactive Brokers |
| Want everything in one place with your existing bank | Check your bank's platform, then check what you're paying |
Wealthsimple — best for beginners and small contributions
Strengths: $0 commissions on stocks and ETFs, $0 on options, no account minimum, genuinely the best mobile experience in Canada, and fractional share support that makes a $200 monthly contribution work properly.
The catch is FX. Wealthsimple's core plan charges a 1.5% currency conversion fee on US trades. On a TFSA that holds US-listed ETFs and receives US dividends, that fee applies repeatedly rather than once.
Wealthsimple's higher-tier plans reduce or waive the FX fee, and it now offers a built-in Norbert's Gambit feature — in beta, web only — that journals DLR for a flat $9.95 plus tax, which beats the 1.5% fee above roughly $800 converted.
Best for: someone contributing $100–$500 a month, mostly into Canadian-listed ETFs, who values simplicity over control.
Questrade — best all-round self-directed TFSA
Strengths: $0 commissions on stocks and ETFs as of 2026, the widest range of account types in Canada, proper USD account support inside registered accounts, fractional shares, and a platform with real depth.
The FX consideration: Questrade's conversion fee is lower than the banks' but still meaningful, which is why Questrade users are the heaviest practitioners of Norbert's Gambit. Being able to run the gambit inside a registered account is the actual reason to choose Questrade over Wealthsimple for a US-heavy TFSA.
Best for: an investor whose TFSA holds US-listed positions, or who wants room to grow into options and more complex account structures without switching platforms later.
We compare these two head-to-head in Questrade vs Wealthsimple Trade 2026.
Qtrade Direct Investing — best research and service
Qtrade consistently rates near the top of Canadian broker rankings for research tools, customer service, and platform quality, and offers $0 commissions on stocks and ETFs.
It has also run some of the most aggressive transfer-in promotions in the market — including a 1% match on net new transfers between $25,000 and $2 million, to a maximum of $20,000, paid in equal monthly instalments over 24 months, with clawback if you withdraw beyond a set threshold during the hold period.
Best for: an investor with an existing balance to move who wants a serious platform and values research over app polish.
Interactive Brokers — lowest FX cost, highest complexity
IBKR offers by far the cheapest currency conversion available to Canadian retail investors, and the lowest margin rates, with access to global markets well beyond North America.
The cost is usability. The platform is built for professionals. Account setup is more involved, the interface is dense, and the learning curve is genuinely steep for a first-time investor.
Best for: someone whose TFSA is large, US-heavy or globally diversified, and who is comfortable with a professional-grade platform.
The bank platforms
TD Direct Investing, RBC Direct Investing, BMO InvestorLine, CIBC Investor's Edge and Scotia iTRADE all offer TFSAs, and they all have the same structural problem: they were built for a world where $9.95 per trade was normal.
Several have introduced commission-free tiers or reduced pricing. Verify what your account actually pays before assuming you're fine — many long-standing customers are still on legacy pricing they've never checked.
The real argument for a bank platform is consolidation: seeing your chequing, savings and TFSA in one login, and the ability to walk into a branch. That is a genuine benefit for some people. It is worth roughly what you're paying for it, which is the calculation nobody makes.
The two things that actually decide it
Do you hold US-listed securities in your TFSA?
If no — you're in VFV, XEQT, ZSP or similar Canadian-listed funds — FX barely matters and Wealthsimple is probably the best answer for most people.
If yes, FX becomes your largest recurring cost and you want a broker that supports USD inside registered accounts. That points to Questrade or IBKR.
Also worth knowing before you load a TFSA with US-listed holdings: US dividends paid into a TFSA are subject to a 15% withholding tax you cannot recover, which doesn't apply in an RRSP. That's covered in the 15% tax that quietly eats your US dividends and it may change which account you use rather than which broker.
How much are you contributing at a time?
The 2026 TFSA limit is $7,000, with cumulative room up to $109,000 for someone eligible since 2009 — see TFSA contribution limit 2026. If you're contributing a few hundred dollars monthly, fractional share support is the difference between being fully invested and leaving $180 in cash because a share costs $380.
Switching is easier than you think
If you're already at a broker that doesn't fit, moving a TFSA does not cost you contribution room and does not require selling anything. Your old broker charges a transfer-out fee, typically $135–$150, and most receiving brokers reimburse it. Full walkthrough: how to transfer a TFSA or RRSP to another broker.
Frequently asked questions
What is the best broker for a TFSA in Canada?
For most beginners, Wealthsimple — $0 commissions, fractional shares, and the simplest experience. For investors holding US-listed securities, Questrade or Interactive Brokers, because both support holding US dollars inside a registered account and reduce the recurring FX cost.
Can I hold US dollars in a TFSA?
Yes, if your broker supports it. Questrade and Interactive Brokers do. Some platforms automatically convert USD balances back to Canadian dollars, which means you pay a currency spread on every US dividend you receive.
Do I pay tax on US dividends in a TFSA?
Yes. US-listed holdings in a TFSA are subject to a 15% US withholding tax on dividends that cannot be recovered or credited. The Canada-US tax treaty exempts RRSPs from this, but not TFSAs.
Is Wealthsimple or Questrade better for a TFSA?
Wealthsimple is better if you contribute small amounts regularly and hold mostly Canadian-listed ETFs. Questrade is better if you hold US-listed securities, want USD support inside the TFSA, or expect to use more advanced account features later.
Does it cost anything to move my TFSA to a different broker?
Your current broker typically charges $135–$150 to transfer out, but most receiving brokers reimburse that fee, often up to $150–$200 per account. The transfer itself does not affect your contribution room.
What is the TFSA contribution limit for 2026?
$7,000 for 2026, with cumulative room of up to $109,000 for someone who has been eligible since the TFSA launched in 2009 and has never contributed.
