Norbert's Gambit

The problem it solves: conversion fees you never see

When you convert CAD to USD at a bank or brokerage, there is rarely a line item called "fee". The cost hides in the exchange rate itself: most brokerages mark up the rate by roughly 1.5% to 2% each way (as of July 2026). Convert $50,000 and you quietly pay several hundred dollars; convert it back later and you pay again.

Norbert's Gambit sidesteps the markup by never asking the broker to convert your cash at all. Instead, you move value across the border inside a security that trades in both currencies, and the exchange happens at close to the wholesale rate built into the security's prices.

The mechanics, step by step

The technique relies on securities that are interlisted: the exact same security trades on a Canadian exchange in Canadian dollars and on a US exchange (or a US-dollar line of the same exchange) in US dollars. Because both listings represent the same asset, the two prices embed the current exchange rate. The steps:

• Buy the security in the currency you have. To go from CAD to USD, buy the Canadian-dollar listing.
• Ask your broker to journal the shares to the other listing. This is a bookkeeping transfer, not a trade: the same shares simply move to the other currency side of your account. Some brokers do this automatically; others need a phone call or message.
• Sell the shares on the other listing, receiving the proceeds in the other currency.
• The cash that lands in your account has been converted at roughly the rate embedded in the two market prices, which is close to the institutional spread.

The classic vehicle: a currency ETF built for the job

You can run the gambit with any interlisted security, but the commonly used vehicle is an interlisted currency ETF that simply holds US cash. The best-known example trades on the TSX under two tickers: DLR in Canadian dollars and DLR.U in US dollars. Because the fund holds US dollars, its value barely moves, which strips most market risk out of the manoeuvre: you buy DLR with CAD, journal to DLR.U, and sell for USD.

For large conversions, some investors use an interlisted stock instead, such as a big Canadian company listed on both the TSX and the NYSE, because heavily traded stocks have very tight bid-ask spreads. The trade-off is that a stock's price can move meaningfully while you hold it.

Costs and risks

The gambit is cheap, not free. You pay two commissions, one to buy and one to sell, plus the bid-ask spread on each side. On a currency ETF the spread is small but real, typically a cent or two per unit.

The bigger variable is settlement timing. Some brokers let you journal and sell the same day, so your exposure lasts minutes. Others require the purchase to settle before the shares can be journaled and sold, which leaves you holding the security for a day or two. With a currency ETF that mostly means exchange-rate drift; with an interlisted stock it means genuine price risk. Check how your broker handles the journaling step before you start.

Where it works

The gambit works in taxable accounts at essentially any brokerage that supports journaling. It can also work inside many RRSP and TFSA accounts, provided the broker offers a US-dollar side for the account and will journal between listings. Policies differ meaningfully from broker to broker, so confirm the details, including whether a phone request is needed, with yours before committing a large amount.

Tax: small numbers, but keep records

In a non-registered account, each round of the gambit is a purchase and a sale, so it has tax consequences even when the goal is just currency conversion. With the currency ETF version, the gain or loss is usually tiny because the fund's value barely moves, but you must still track your adjusted cost base and report the disposition.

With an interlisted stock, price movement between purchase and sale can create a real capital gain or loss. And if the sale produces a loss, the superficial loss rule can deny it when you or an affiliated person rebuys the same security within 30 days. Inside an RRSP or TFSA, none of this applies, since gains and losses there are not taxable events.

When it is not worth the trouble

For small conversions, skip it. If your broker charges $10 per trade, the gambit's floor cost is about $20 plus spread, and the multi-step process takes attention. Converting a few hundred or even a couple of thousand dollars, the simple conversion fee often costs about the same or less than two commissions and the hassle. The gambit earns its keep on four-figure conversions and becomes compelling on five-figure ones.
