Best Cards for US Purchases in Canada: Beating the 2.5% FX Fee
Most Canadian cards quietly add 2.5% to every US dollar you spend. Here's what actually avoids it — no-FX credit cards, USD cards, and multi-currency accounts like Wise.

The fee nobody quotes you
When you buy something in US dollars — a flight, a software subscription, a hotel in Buffalo — your Canadian card does two things:
- Converts USD to CAD at the network rate (Visa or Mastercard's wholesale rate, which is genuinely competitive).
- Adds a foreign transaction fee, almost always 2.5%, on top.
That 2.5% is the issuer's, not the network's. It applies to any transaction processed in a foreign currency — including US-based websites that bill in USD even though you never left the couch.
The math is blunt: on $5,000 USD/year of spending, the FX fee alone costs you roughly $170 CAD. That is more than most annual fees.
Watch for dynamic currency conversion
At a US checkout or ATM you'll sometimes be asked "would you like to pay in CAD?" Always say no. That is dynamic currency conversion — the merchant's processor picks the exchange rate, typically well off the network rate, and your card's FX fee may still apply on top. Choosing USD hands the conversion back to Visa or Mastercard.
Option 1: A no-FX-fee Canadian credit card
The cleanest fix. A handful of Canadian cards waive the 2.5% entirely, so you pay the network rate and nothing else.
| Card | Annual fee | FX fee | Notes |
|---|---|---|---|
| Scotiabank Gold American Express | $120 | 0% | Elevated earn on groceries, dining and entertainment. Amex acceptance is the catch. |
| Scotiabank Passport Visa Infinite | $150 | 0% | Visa acceptance, lounge passes, Scene+ points. |
| Home Trust Preferred Visa | $0 | 0% | No fee, no frills, 1% cash back. The default pick for occasional US spend. |
| Brim Financial cards | $0 and up | 0% | No-FX across the lineup. |
| Rogers Red World Elite | $0 | charged, then largely rebated | Effectively close to neutral, but you float the fee first. |
Most of the rest of the Canadian market — Amex Cobalt, TD Aeroplan, CIBC Dividend, BMO CashBack, Tangerine — charges the full 2.5%.
The break-even
A no-FX card with an annual fee only makes sense if the FX you save exceeds the fee you pay. At 2.5%, a $120 annual fee needs roughly $4,800/year of foreign spend to break even on FX alone — before counting any rewards.
Under that? Home Trust Preferred at $0 is the honest answer.
Option 2: A USD credit card
Canadian banks issue US-dollar credit cards. They bill in USD and charge no conversion — but you have to pay them in USD, which means you still need to buy US dollars somewhere.
These make sense if you:
- Earn USD income, or
- Cross-border shop constantly and already hold a USD chequing account.
They make little sense for a once-a-year Florida trip. You've just moved the conversion problem one step upstream.
Option 3: Wise and multi-currency accounts
Wise (formerly TransferWise) is where this conversation has moved. It's a multi-currency account with a debit card, not a credit card, and that distinction matters more than the fee difference.
How it works: you hold balances in CAD, USD and dozens of other currencies. You convert CAD to USD inside the app at the mid-market rate — the rate you see on Google — plus a transparent conversion fee that is a fraction of a percent rather than 2.5%. Spending from a funded USD balance then costs nothing extra.
Where Wise wins
- Conversion is far cheaper than 2.5%, and you see the fee before you convert.
- You can convert when the rate looks good and hold the USD.
- Local account details in USD and other currencies — useful for freelancers invoicing US clients.
- No annual fee.
Where Wise loses
- It's a debit card. No purchase protection, no extended warranty, no rental-car collision damage waiver, no travel medical insurance. For a car rental or a large purchase, that's a real gap.
- Weaker recourse. A debit dispute takes the money out of your account first and gives it back later. A credit dispute doesn't.
- No rewards. No points, no cash back.
- Hotel and rental holds freeze your actual cash, not a credit line.
- It doesn't build Canadian credit history.
Comparable options: Wealthsimple Cash, EQ Bank's card and Revolut all offer some version of cheap or rebated conversion in Canada. All are debit or prepaid, and all share the same insurance gap.
What we'd actually carry
Assume $5,000 USD of annual US spending:
| Approach | Approx. FX cost | Insurance | Rewards |
|---|---|---|---|
| Regular Canadian card at 2.5% | ~$170 CAD | Yes | Yes |
| Home Trust Preferred ($0 fee, 0% FX) | $0 | Minimal | 1% |
| Scotiabank Passport ($150 fee, 0% FX) | $150 fee vs ~$170 saved | Strong | Yes |
| Wise (sub-1% conversion) | ~$25–$50 CAD | No | No |
- Occasional US spend, want it simple: Home Trust Preferred Visa. Zero fee, zero FX, done.
- Frequent traveller who wants insurance and points: Scotiabank Passport Visa Infinite or Scotiabank Gold Amex. The fee roughly pays for itself around $5–6k of foreign spend and you keep the coverage.
- Freelancer paid in USD, or converting large amounts: Wise for the conversion — but pair it with a credit card for anything that needs purchase protection or a rental car.
- Never travel with only a debit card. Use Wise for the conversion and the credit card for the risk.
The one thing to fix today
If you buy from US sites regularly and you're still on a 2.5% card, the highest-return move in this article is applying for a no-fee, no-FX card and using it only for USD transactions. It costs nothing to hold and saves 2.5% forever.
