Short answer: Norbert's Gambit is a way to convert CAD to USD (or back) at close to the real mid-market exchange rate, by buying a TSX-listed ETF in one currency and selling the same ETF's interlisted units in the other — instead of taking your bank's marked-up "no-fee" conversion rate. On a $50,000 conversion, the difference between a typical bank spread and the Gambit is commonly $500-$1,000.

The problem it solves

When your bank converts CAD to USD "for free," it isn't actually free — it just charges you through the exchange rate instead of a line-item fee. Big 5 Canadian banks typically mark the rate up 2-3% against you, so a "free" $50,000 conversion can quietly cost $1,000-$1,500 versus the real mid-market rate you'd see on Google or XE.com. Wire services and drafts usually aren't much better. Norbert's Gambit exists because there's a cheaper path if you're willing to do a bit of your own trading.

How it actually works

The mechanism relies on a small number of Canadian ETFs that are interlisted — the same underlying position trades under two ticker symbols, one priced in CAD and one in USD. The one almost everyone uses is Global X's US Dollar Currency ETF (ticker DLR in CAD, DLR.U in USD — the fund was previously branded under Horizons ETFs before Global X's 2024 rebrand, so older articles and broker help pages may still say "Horizons DLR"). Both tickers represent the same USD cash position; the only difference is which currency you're trading it in.

Converting CAD → USD: Buy DLR on the TSX with your CAD.
Move it to the USD listing: Either sell DLR and buy DLR.U as a second trade, or — if your broker supports it — request a "journal" (sometimes called a "swap" or "exchange"), which moves the same underlying shares onto the DLR.U symbol without a second market trade.
Sell DLR.U for USD, or simply hold/withdraw it as USD if your account supports holding US-dollar positions.

Going the other direction (USD → CAD) is the same process in reverse: buy DLR.U with USD, journal or sell into DLR, then sell DLR for CAD.

What you're actually paying

Instead of your bank's 2-3% markup, you're paying two much smaller things: the ETF's own bid-ask spread (DLR/DLR.U's is typically small — commonly cited around 0.15-0.17% all-in for a same-day round trip) and your brokerage's trade commission(s). At many self-directed Canadian brokerages, ETF trades are free or a few dollars each; at others they run $5-$10 per trade. Either way, the total is usually a small fraction of what a bank spread costs on any meaningful amount.

Worked example

Converting CA$50,000 to USD, bank vs. Norbert's Gambit, at a 1 CAD = 0.72 USD mid-market rate.

Your bank, 2.5% spread: $50,000 × 0.72 = $36,000 mid-market value. After a 2.5% spread, you receive roughly $35,100 USD.

Norbert's Gambit, ~0.15% ETF spread + two $5 trade commissions: You receive roughly $35,936 USD — about $836 more than the bank, for the cost of two brokerage trades and a bit of your own time.

Doing it in a registered account

Norbert's Gambit works inside RRSPs, TFSAs, and other registered accounts too, provided your brokerage supports holding US-dollar-denominated ETFs there — and it comes with a real advantage in that setting: there's no capital-gains tracking to worry about inside a registered account, since nothing inside one is taxable on disposition. Outside a registered account, the tax picture is a bit more involved — see below.

Common mistakes

⚠️Holding DLR/DLR.U overnight "to wait for a better rate"

The Gambit is a conversion technique, not a trade you hold for a view on currency movement. Holding overnight exposes you to the ETF's own price movement on top of the FX rate you were trying to lock in, and it accrues the fund's own management fee pro-rated for however long you hold it — small on a one- or two-day round trip, but pointless to pay if you don't have to. Execute it same-day, in one sitting, whenever you can.

ℹ️Assuming it's tax-free because "it's just a currency conversion"

Outside a registered account, selling DLR or DLR.U shares is technically a disposition for capital-gains purposes, even when the sale is just one leg of a same-day conversion — you're expected to track adjusted cost base like any other security. In practice, a same-day round trip usually produces a negligible gain or loss (the price barely moves), but "negligible" isn't the same as "not reportable." Keep your trade confirmations.

📋Assuming journaling is free at your broker

Journaling used to be free or close to it at most self-directed brokers — that's no longer universal. Questrade, for one, introduced a journal fee (around $10) in April 2025. Check your own broker's current fee schedule before assuming a "1 trade" journal beats a plain buy-then-sell — at some brokers now, it doesn't.

ℹ️Doing it for small amounts

The Gambit's costs are mostly fixed (trade commissions) while a bank's cost scales with the amount. Below a few hundred dollars, the fixed commissions can outweigh what you'd save on the spread — for a small transfer, a percentage-fee service like Wise is often simpler and just as cheap.

When something else beats it

If you already hold an account with a brokerage that offers its own low-cost currency conversion desk — Interactive Brokers is the commonly cited example, with a published 0.002% commission (a small flat minimum) and no added spread on a client-initiated conversion — that can undercut a commission-bearing Norbert's Gambit outright, especially on smaller amounts. The Gambit's real audience is people who don't already have (or want) that kind of account: it turns any ordinary Canadian self-directed brokerage into a low-spread currency exchange, without opening anything new.
