Is Norbert's Gambit legal and safe?

Yes — it's a normal, widely-used technique that simply involves buying and selling an ordinary ETF. The main risks are small price movements while the trade settles, and getting a step wrong, so go slowly your first time.

Which broker is best for it?

Most Canadian discount brokerages allow it, but the ease varies — some journal the shares automatically, others need a phone call, and a few charge a small fee. Check your broker's process before you start.

Norbert's Gambit: How to Convert CAD to USD Cheaply

Updated June 2, 2026

If you’ve ever moved money between Canadian and US dollars in an investment account, you may have paid a hefty hidden fee — often around 1.5% — buried in the exchange rate. On $20,000, that’s about $300. Norbert’s Gambit is a do-it-yourself trick to convert currency at close to the real rate for just the cost of a couple of trades.

The idea in one sentence

You buy an ETF that trades in both Canadian and US dollars, then sell the other side — effectively swapping currencies at the market rate, skipping your broker’s markup.

The usual tool is DLR (trades in CAD) and DLR.U (the exact same fund, trades in USD).

When it’s worth it

Because you pay two fixed trade commissions, the gambit only beats the broker’s percentage fee above a break-even amount. Here’s roughly what you’d save versus a 1.5% broker fee, assuming ~$10 commissions and a small spread:

Amount converted	Broker’s FX fee	Gambit cost	You save
$2,000	$30	~$22	~$8
$5,000	$75	~$25	~$50
$10,000	$150	~$30	~$120
$25,000	$375	~$45	~$330
$50,000	$750	~$70	~$680

For a few hundred dollars it’s not worth the hassle; for several thousand, it adds up fast. The Norbert’s Gambit calculator shows your exact savings and break-even point.

Step by step (CAD → USD)

Buy DLR (the Canadian-dollar version) with your Canadian cash.
Wait for it to settle — typically a couple of business days. (Selling before settlement is what causes problems.)
“Journal” the shares to DLR.U — this tells your broker the same shares should now show as the US-dollar version. Some brokers do this automatically; others need a quick phone call or online request.
Sell DLR.U to receive US dollars.

To go the other way (USD → CAD), you do the same thing in reverse: buy DLR.U with US dollars, journal to DLR, and sell DLR for Canadian dollars.

The risks (and how to manage them)

Settlement delay: the price of DLR can drift while you wait the day or two to journal and sell. Since DLR tracks the US dollar, the risk is small, but it’s not zero. Don’t do it with money you need locked to the penny.
Doing a step wrong: the most common mistake is selling before settlement, or selling the wrong side. Go slowly the first time, and consider calling your broker to walk through it.
Broker quirks: a few brokers charge a journalling fee or have an awkward process. Check first.

Is it worth your time?

For a one-off small conversion, probably not — just pay the fee and move on. But for larger sums (moving money into US-listed investments, funding a US-dollar account, or converting investment proceeds), the savings can easily be hundreds of dollars for ten minutes of work.
