WealthBroker FX Fees in Canada: The Hidden CAD↔USD Conversion Cost
Quick FX cost calculator — what would your conversion cost?
Estimate based on a ~1.5% one-way spread (≈3% round trip) vs Norbert's Gambit at a fixed ~$10. Brokers' published rates vary — verify before converting.
1. What a currency conversion fee actually is
When you convert Canadian dollars into US dollars (or back), your broker doesn't give you the "mid-market" rate you see on Google or on the Bank of Canada's website. It applies its own rate, which includes a markup — usually called the FX spread or currency conversion fee.
Three things worth understanding:
- It's baked into the rate, not billed separately. Your confirmation shows "rate applied: 1.3703" instead of 1.3500 — and that's it. There is no "conversion fee" line anywhere.
- It's documented. The percentage is printed in each broker's published fee schedule, usually under "currency conversion" or "foreign exchange". Nothing secret about it — just easy to miss.
- It applies in both directions. CAD→USD when you buy, USD→CAD when you sell. A full round trip doubles the cost.
| Broker | Published conversion fee | USD account available |
|---|---|---|
| Wealthsimple | 1.5% | With a paid plan ($10/month) |
| Questrade | Up to ~2% (unless USD account) | Native USD accounts included |
| Disnat (Desjardins) | 1.75% | Yes |
| Bank-owned online brokers | Typically 1.5% to 2% | Varies by institution |
| Interactive Brokers | A small fraction of 1% (modest per-conversion minimum) | N/A — institutional-grade FX |
Figures are drawn from each broker's published fee schedule at time of writing (June 2026) and can change at any time.
2. What the published fee schedules say
Here are the CAD↔USD conversion fees at the major Canadian online brokers, according to their published fee schedules at the time of writing (June 2026):
| Broker | Published conversion fee | USD accounts |
|---|---|---|
| Wealthsimple | 1.5% | Available with a paid plan ($10/month per published pricing) |
| Questrade | Up to ~2% (unless you use a USD account) | Native USD accounts included |
| Disnat (Desjardins) | 1.75% | USD accounts available |
| Bank-owned online brokers | Typically 1.5% to 2% | Varies by institution |
These figures come from the brokers' published fee schedules and can change at any time. Always check the current schedule on the broker's official website before opening an account.
Two more worth knowing if you trade US securities: Qtrade applies a currency conversion fee in the same general range as the others per its published schedule, while Interactive Brokers stands out for institutional-grade FX at a small fraction of 1% (with a modest per-conversion minimum) — typically the cheapest of the bunch for frequent US trading, at the cost of a steeper learning curve. As always, confirm the current rate on each broker's own fee page before you rely on it.

3. The math on a US$10,000 purchase
Let's run a concrete example with a mid-market rate of US$1 = C$1.3500:
- With no markup: US$10,000 should cost C$13,500.
- With a 1.5% markup: the applied rate climbs to ~1.3703. You pay ~C$13,703.
- The gap: about C$203 (≈ US$150) — on a single purchase, with no "fee" appearing anywhere.
And that's only one way. The day you sell the position and bring the money back into Canadian dollars, the same mechanics apply in reverse. A full round trip costs roughly 3% of the amount — about $300 on a $10,000 position.
For perspective: the classic $9.95 trading commission that zero-commission platforms famously eliminated is roughly fifteen times smaller than the conversion cost on a $10,000 purchase.
| Amount converted | One way (~1.5%) | Round trip (~3%) |
|---|---|---|
| $1,000 | ~$15 | ~$30 |
| $5,000 | ~$75 | ~$150 |
| $10,000 | ~$150 | ~$300 |
| $25,000 | ~$375 | ~$750 |
| $50,000 | ~$750 | ~$1,500 |
| $100,000 | ~$1,500 | ~$3,000 |
4. The cost by amount converted
| Amount converted | One way (~1.5%) | Round trip (~3%) |
|---|---|---|
| $1,000 | ~$15 | ~$30 |
| $5,000 | ~$75 | ~$150 |
| $10,000 | ~$150 | ~$300 |
| $25,000 | ~$375 | ~$750 |
| $50,000 | ~$750 | ~$1,500 |
| $100,000 | ~$1,500 | ~$3,000 |
The cost is proportional, but it compounds quickly with frequency:
- Recurring purchases: $500/month into a US-listed ETF means 12 conversions a year — about $90/year in FX costs, every single year.
- US dividends: paid into a CAD account, every quarterly payment goes back through the conversion. A US$1,000 annual dividend stream quietly costs an extra ~$15/year.
5. Why you never see it
Unlike a commission, the conversion fee never generates a line on your statement: it is folded into the exchange rate you receive. That's what makes it so discreet — and so easy to underestimate.
You can measure it yourself in three steps:
- Note the rate applied to your trade (on the execution confirmation or your statement).
- Find the mid-market rate at the same time — the Bank of Canada's published daily rate is a solid reference.
- Compute the gap:
(applied rate − mid-market rate) ÷ mid-market rate. Example: (1.3703 − 1.3500) ÷ 1.3500 ≈ 1.5%.
6. The documented alternatives
Norbert's Gambit: ~$10, whatever the amount
The best-known way around the conversion fee: buy a security listed in both CAD and USD (typically DLR.TO / DLR.U.TO), ask your broker to journal it to the USD version, then sell. Total cost: two commissions and one journal entry — about $10, whether you convert $5,000 or $100,000. On $50,000, that's roughly $740 in savings compared with a standard 1.5% conversion.
We have a step-by-step guide: Norbert's Gambit — convert CAD↔USD for almost nothing.
Native USD accounts: convert once, not twenty times
A US-dollar account keeps your USD in USD: sale proceeds stay in USD, US dividends land in USD, and you only convert once — or never. Per the published fee schedules: Questrade includes native USD accounts, Wealthsimple offers them with a paid plan ($10/month, or $120/year), and Disnat offers USD-denominated accounts. The break-even math is simple: at 1.5%, a $120/year plan pays for itself once you avoid about $8,000 in conversions per year.
Canadian-listed US-equity ETFs: zero conversion
A third option that often gets overlooked: get your US exposure through an ETF listed in Toronto in Canadian dollars (VFV instead of VOO, for example). You buy and sell in CAD with no conversion out of your own pocket — the currency exchange is handled inside the fund at institutional cost. Our comparison XEQT vs VEQT vs VFV covers these options in detail.
Lean Norbert's Gambit
- Occasional conversions of $5,000 or more
- One-off or infrequent US purchases
- You're comfortable with a 1-3 business day round trip and two commissions
- Fixed cost of about $10, regardless of the amount
Lean native USD account
- Frequent US trades or large US exposure (tipping point around $25,000 of US exposure)
- Regular US dividends landing in a CAD account
- You want to convert once — or never — instead of on every trade
- Willing to pay a plan fee (e.g. $10/month) in exchange for no per-trade conversion
7. When it's worth the effort (and when it isn't)
- Occasional conversions under ~$5,000: often not worth the hassle. Norbert's Gambit takes 1 to 3 business days and two commissions; on $1,000, the standard fee is only ~$15.
- Conversions of $5,000 and up: Norbert's Gambit eliminates nearly all of the 1.5% for a fixed cost of about $10.
- Frequent US trades or large US exposure: a native USD account changes the economics of the whole portfolio — our detailed comparison puts the tipping point around $25,000 of US exposure.
- Regular US dividends: a USD account avoids a conversion on every single payment.
- A portfolio built entirely of Canadian-listed ETFs: this barely affects you — the currency exchange happens inside the funds.
Either way, the fee applies in registered accounts too: TFSA, RRSP or non-registered, the conversion is priced at the same rate per the broker's schedule.
Frequently Asked Questions
Why doesn’t the conversion fee show up on my statement?
Because it is built into the exchange rate you receive rather than billed as a separate line item. To estimate it, compare the rate applied to your trade with the mid-market rate at the same time — the Bank of Canada’s published daily rate is a good reference.
Is it a hidden or prohibited fee?
No. The conversion fee appears in each broker’s published fee schedule — it is a common pricing model, especially among commission-free brokers. It is simply easy to miss because it never shows up as a separate charge.
Does the fee apply inside a TFSA or RRSP?
Yes. CAD↔USD conversion applies regardless of account type, registered or not. Some brokers do offer registered accounts denominated in USD per their published pricing, which avoids converting on every trade.
Are US-dollar dividends converted too?
Yes. If your US stocks pay dividends into a Canadian-dollar account, every payment goes through the conversion (~1.5% per the broker’s schedule). A USD account keeps those dividends in USD, with no conversion.
What’s the best-known way to reduce this cost?
Norbert’s Gambit: a round trip through a security listed in both CAD and USD (such as DLR.TO/DLR.U.TO), which brings the total cost to about $10 regardless of the amount. It generally becomes worthwhile above roughly $5,000 per conversion.
