Norbert's Gambit Explained: The Cheapest Way to Convert CAD to USD

Canadian brokers charge 1.5% to 2.5% to convert your dollars. On a $100,000 conversion, that's $1,500 to $2,500 you'll never see again. Norbert's Gambit cuts that to about $20 in trading commissions.

It's the single best workaround Canadian investors have for avoiding the FX markup your broker quietly pockets every time you convert currency. It's not complicated. It just takes a little planning, a broker that supports it, and the patience to not panic when your shares say "pending" for 3 days.

Where the name comes from

Norbert Schlenker is a Certified Financial Planner from Salt Spring Island, British Columbia. In December 2001, he posted a detailed explanation of a currency conversion workaround on "The Wealthy Boomer," a Canadian investing forum started by Financial Post columnist Jonathan Chevreau. He'd been using the method himself for years before that.

The forum community started calling it "Norbert's Gambit," and the name stuck. The Wealthy Boomer eventually became the Financial Wisdom Forum, which still hosts some of the original discussions. It's one of those rare cases where a genuinely useful retail investing strategy got named after the person who shared it first, not the institution that figured out how to charge for it.

(Wealthsimple actually brought Schlenker out on stage at a product event in 2025. Twenty-four years later, the strategy he posted on a forum is still the best answer Canadians have for cheap currency conversion. That tells you something about how little has changed in Canadian FX pricing.)

How it actually works

The concept is almost embarrassingly simple. Some securities trade on Canadian exchanges in CAD and on US exchanges (or in USD) simultaneously. You buy the security in one currency and sell it in the other. No bank FX desk involved. No 1.5% markup quietly baked into your exchange rate.

The standard vehicle today is DLR.TO (listed in CAD) and DLR.U (listed in USD). They're the same ETF, the Global X US Dollar Currency ETF, just priced in different currencies. DLR holds US dollar cash equivalents, so its value tracks the USD/CAD exchange rate directly. That's important: unlike a stock, DLR won't swing 3% on an earnings report while you're waiting for your trade to settle.

Here's the process:

1. Buy DLR.TO in the CAD side of your brokerage account, using Canadian dollars
2. Contact your broker (or submit an online request) to "journal" your DLR.TO shares to DLR.U on the USD side of your account. This step varies by broker and potentially isn't required at all.
3. Wait for the journal to complete (1 to 5 business days, depending on your broker)
4. Sell DLR.U from the USD side of your account and receive US dollars

That's it. Four steps, maybe 10 minutes of actual work, and a few days of waiting. You've converted CAD to USD at the market exchange rate, minus a small trading commission and the bid-ask spread on DLR (typically about $0.01 per share). Your bank would've charged you hundreds or thousands for the same thing.

Before DLR existed (it launched in 2011), people used interlisted bank stocks like Royal Bank (RY on the TSX, RY on the NYSE) or TD (TD.TO and TD on the NYSE). Some still do for very large conversions where the higher share price means a tighter percentage spread. But DLR is simpler for most people because it removes stock price risk from the equation. You're not betting on RY's next earnings call while you wait for your shares to journal.

The math on what you save

On a $100,000 CAD to USD conversion through RBC Direct Investing, Norbert's Gambit costs $19.90 in trading commissions ($9.95 to buy DLR.TO, $9.95 to sell DLR.U). RBC's standard FX markup is about 2%. On $100,000, that would've been roughly $2,000.

I saved about $1,980 on a single conversion. That's not a typo.

Here's what the savings look like at different amounts, assuming a typical 1.5% broker FX markup. Norbert's Gambit costs roughly $10 to $20 per conversion (commissions plus the bid-ask spread on DLR, plus a journaling fee at some brokers).

$10,000 conversion: $150 in FX fees vs. ~$10-20 for Norbert's Gambit. You save ~$130.

$25,000 conversion: $375 in FX fees vs. ~$10-20. You save ~$355.

$50,000 conversion: $750 in FX fees vs. ~$10-20. You save ~$730.

$100,000 conversion: $1,500 in FX fees vs. ~$20. You save ~$1,480.

The savings scale linearly. The more you convert, the more you keep. And at a 2% to 2.5% FX markup (common at TD and BMO), the numbers get ugly fast. On $50,000 at TD's 2.5% rate, you'd lose $1,250 to the conversion alone. That's real money that could be sitting in your portfolio compounding.

Which brokers support it

Not every Canadian broker handles Norbert's Gambit the same way. Some make it easy. Some make you call and sit on hold while soft jazz plays. And one makes it basically unnecessary. It's one of the things we looked at when we compared Questrade to Wealthsimple.

Interactive Brokers (IBKR)

Commission: ~$1 USD min · FX markup: 0.002-0.03% · NG needed: No

IBKR is the outlier. They charge 0.002% to convert currency with no markup on the exchange rate (minimum $2 USD). On a $10,000 conversion, that's about $2 to $3. Norbert's Gambit on IBKR would actually cost you more in commissions than just converting directly. If you're on IBKR, skip the gambit and use their native currency conversion. It's one of the best things about the platform.

RBC Direct Investing

Commission: $9.95 · FX markup: ~2% · Journaling: Automatic · Timeline: 1-2 business days

RBC is the easiest broker for Norbert's Gambit. You buy DLR.TO in your CAD account and sell DLR.U in your USD account. RBC automatically journals the shares at settlement. No phone call, no online request, no extra fee. You do pay the $9.95 commission on each side. I've used this for a large conversion and honestly, it felt too easy for the amount of money it saved me.

Questrade

Commission: $0 · FX markup: 1.5% · Journaling: Self-serve online · Fee: $9.95 + tax · Timeline: 3-5 business days

Questrade charges no commissions on stock and ETF trades, so your only cost is the $9.95 + tax journaling fee. They added self-serve online journaling in early 2025, which means no more sitting on hold with customer support. For most passive investors doing a few conversions a year, Questrade is hard to beat on total cost.

Wealthsimple

Commission: $0 · FX markup: 1.5% · Journaling: Not currently supported

Wealthsimple is where I've moved most of my accounts. I like the platform. But until they support Norbert's Gambit, you're paying their 1.5% FX markup on every USD conversion. On a $25,000 conversion, that's $375 you don't need to spend.

Update (March 2026): Wealthsimple has started rolling out Norbert's Gambit support in beta for some users, with a $9.95 + tax journaling fee. It's not available to everyone yet. I'll update this section as the feature expands.

TD Direct Investing

Commission: $9.99 · FX markup: 2.5-3.3% · Journaling: Online (Securities Transfers) · Timeline: 2-4 business days

TD has the highest FX markup of the group, which means the savings from Norbert's Gambit are also the largest. They've added an online journaling tool under Securities Transfers, so you don't need to call anymore. If you're at TD and converting anything over $5,000, there's really no excuse not to use Norbert's Gambit.

BMO InvestorLine

Commission: $9.95 · FX markup: ~1.6% · Journaling: Phone call required · Timeline: 2-3 business days

BMO is the most manual. You may still need to phone in to request the journal. There's also a known quirk where BMO cleans up the positive/negative position one business day late, which can generate a small interest charge. It's minor, but it's the kind of thing that makes you question your life choices mid-process.

Which account type to use it in

Short answer: all of them. Norbert's Gambit works in every account type that lets you hold both CAD and USD: TFSA, RRSP, LIRA, FHSA, and non-registered (cash) accounts. The process is the same regardless of the account.

The important difference is tax treatment.

In registered accounts (RRSP, TFSA, FHSA, LIRA), there are no capital gains implications. You buy DLR, journal it, sell DLR.U, and the CRA doesn't care about the tiny gain or loss on the transaction. This is the simplest case.

In a non-registered account, the buy and sell of DLR is technically a disposition. Your broker will report it on a T5008 slip at tax time. Don't panic when you see it. I say this because you will absolutely see it and briefly wonder if you've done something wrong. You haven't. The gain or loss is usually pennies, and you'll need to track the adjusted cost base, but the math is trivial.

One minor tax note: if you use interlisted bank stocks like RY or TD for your conversion instead of DLR, and you hold those stocks elsewhere, the superficial loss rule could apply. Stick with DLR and it's a non-issue.

The bigger question isn't can you do Norbert's Gambit in your account. It's why you're converting currency in the first place. If you're holding US dividend stocks, which account those sit in matters a lot more than the conversion method. (The W-8BEN form with IRS is important to note.) The RRSP gets a 0% withholding rate on US dividends under the Canada-US tax treaty. The TFSA doesn't. That 15% difference compounds. I've written about this in more detail in RRSP vs TFSA for US investing.

When Norbert's Gambit isn't worth it

It's not always the right move. Here's when I'd skip it:

• If you're converting under $1,000, the fixed costs eat into your savings. On a $500 conversion at 1.5% FX markup, you'd pay $7.50 in fees. Norbert's Gambit with a $9.95 journaling fee already costs more than that. Even at $1,000, you're saving maybe $5. Below that threshold, just pay the FX markup and move on.
• If you're already on IBKR, you don't need this. I covered it above, but it's worth repeating. IBKR's native currency conversion is so cheap that Norbert's Gambit is a net negative on that platform. Don't overthink it. Convert directly.
• And if you're converting currency once to fund a long-term portfolio and you're on a platform with reasonable FX rates, the $50 to $100 you save might not justify learning the process. That said, if you're converting $25,000 or more, it's almost always worth the 15 minutes of effort.

The timing trade-off

Here's the thing most guides don't mention: Norbert's Gambit takes time. Depending on your broker, you're looking at 2 to 5 business days from the moment you buy DLR.TO to the moment you have spendable USD.

If a stock you've been watching drops 8% on a Monday morning and you need USD to buy it, Norbert's Gambit isn't going to help. You'll pay the FX markup because you need the money now. That's fine. The FX conversion is instant, and sometimes the cost of waiting is higher than the cost of converting.

Norbert's Gambit rewards planning. If you know you're going to need USD in your account next month, convert now. If you're building a long-term US portfolio, batch your conversions. Don't do $5,000 every month when you could do $30,000 twice a year and save meaningfully each time.

And once you have USD? Keep it in USD. I don't convert back. The whole point of going through this process is to invest in US markets, and converting back to CAD just means you'll pay conversion costs again when you inevitably want to buy something on US exchanges. I'd rather have that money in the market than have it sitting in CAD waiting for my next conversion.

Common mistakes that cost you money

• After the journal completes, make sure you're selling DLR.U from the USD side of your account. I may know someone who, in the excitement of getting the journal confirmation, sold from the CAD side and defeated the entire purpose of the exercise. When things are moving fast, take the extra second to confirm which account you're in. It's a dumb mistake, and it's easy to make.
• Along the same lines: don't sell DLR.TO before the journal finishes. If you do, you've just done a round-trip trade in Canadian dollars. You haven't converted anything. You've paid commissions for nothing. Wait for the confirmation.
• Use limit orders. DLR's bid-ask spread is tight (usually $0.01), but a market order on a less liquid day could cost you more. Set a limit at the ask price when buying and the bid price when selling. It takes 5 extra seconds.
• If you're using interlisted bank stocks instead of DLR (for larger conversions), don't pick one you already hold. RY in your non-registered account plus RY in your TFSA within 30 days could trigger the superficial loss rule. DLR avoids this entirely because you almost certainly don't own it in any other context.
• You'll also notice DLR has a 0.73% MER, which looks expensive on paper. You're holding it for 3 to 5 days. The MER on a 5-day hold costs you practically nothing.

The bottom line

Norbert's Gambit is the cheapest way for Canadians to convert currency for investing. Nobody's going to be impressed at a dinner party when you explain how you journaled ETF shares between currency listings. But the savings are real and the math still works at $10,000 or more. The process is the same in a TFSA, RRSP, LIRA, or non-registered account.

Buy DLR.TO, journal to DLR.U, sell, invest. That's the whole playbook.
