Canadians who hold US investments pay two costs that never appear on a statement: withholding tax on dividends and the spread on every currency conversion. Both are largely avoidable.
The US withholds 15% of dividends paid to Canadians. It is exempt in an RRSP or RRIF under the Canada–US treaty, recoverable as a foreign tax credit in a taxable account, and permanently lost in a TFSA, FHSA or RESP. Broker currency conversion costs roughly 1.5% each way; Norbert’s Gambit — buying DLR on the TSX and journaling it to DLR.U — reduces that to near zero. Foreign property over $100,000 of cost in taxable accounts triggers annual T1135 reporting.
The United States taxes dividends paid to foreign investors at source. The Canada–US tax treaty reduces the standard 30% rate to 15% for Canadian residents — and exempts certain retirement accounts entirely. Your broker handles the paperwork; the tax is simply deducted before the dividend reaches you.
Where the 15% ends up depends entirely on which account holds the security:
| Account | What happens to the 15% | Net effect |
|---|---|---|
| RRSP / RRIF | Not withheld at all — treaty exemption | No cost |
| Taxable (non-registered) | Withheld, then recovered via the foreign tax credit | No net cost, but the dividend is fully taxable as foreign income |
| TFSA | Withheld, no credit available | Permanently lost |
| FHSA / RESP / RDSP | Withheld, no credit available | Permanently lost |
The reason the TFSA loses out is structural rather than punitive. A foreign tax credit works by reducing Canadian tax owing on that income — and a TFSA generates no Canadian tax to reduce. There is nothing to credit the withholding against, so it is gone.
How much does this cost? On a broad US equity ETF yielding around 1.5%, losing 15% of that is roughly 0.22% a year. That is more than the entire management fee of most index ETFs. It is not catastrophic, and it is not a reason to avoid US equities in a TFSA if that is where your room is — but it should be a deliberate choice rather than an accident.
If you hold both a TFSA and an RRSP and want US exposure, the efficient arrangement is US dividend payers in the RRSP and Canadian or global-growth holdings in the TFSA. If you only have a TFSA, hold the US exposure there anyway — a 0.22% drag inside a permanent tax shelter still beats holding it in a fully taxable account.
This is where it gets genuinely technical, and it is the part almost no Canadian investor knows. When you buy US exposure, there are three different structures, and withholding behaves differently in each.
| Structure | Example type | In an RRSP | In a TFSA |
|---|---|---|---|
| US-listed ETF holding US stocks | Bought on a US exchange in USD | No withholding — treaty applies | One layer withheld |
| Canadian-listed ETF holding US stocks directly | A Canadian fund that owns the shares itself | One layer withheld | One layer withheld |
| Canadian-listed ETF that holds a US-listed ETF | A “wrapper” fund | One layer withheld | Two layers — the worst case |
The treaty exemption only applies when the RRSP itself is the direct holder of the US security. Put a Canadian-listed fund in between and the exemption is broken, because the fund — not your RRSP — is the holder receiving the dividend.
The worst case is a Canadian ETF that wraps a US-listed ETF, held in a TFSA: withholding is applied when the US companies pay the US ETF, and again when the US ETF pays the Canadian fund. Two layers of leakage on the same dividend.
Converting Canadian dollars to US dollars at a mainstream broker costs roughly 1.5% each way, buried in the exchange rate rather than charged as a visible fee. On $50,000 that is about $750 — invisible, and larger than a decade of ETF fees.
Norbert's Gambit — named after the Canadian financial writer Norbert Schlenker — sidesteps this using a security that trades in both currencies. The most common vehicle is the DLR / DLR.U pair on the TSX: the same fund, quoted in Canadian dollars as DLR and in US dollars as DLR.U.
Total cost: two commissions (often $0–$20 combined) plus the bid-ask spread on a highly liquid security, so realistically under $50 — against roughly $300 for a straight conversion at 1.5%.
What can go wrong. Journaling before settlement can cause the trade to fail or leave the account short. A small price move between buying and selling creates a tiny gain or loss — DLR is designed to minimise this but it is not zero. And in a taxable account the gambit creates a reportable disposition, usually trivially small but still requiring reporting. For amounts under a few thousand dollars, the effort generally is not worth it.
For many Canadians the better answer is to avoid the conversion entirely by holding a Canadian-listed ETF that provides US or global exposure. You pay a small amount of withholding leakage instead of a large FX spread, you never touch US dollars, and there is nothing to journal. That is a completely reasonable choice — Norbert's Gambit matters most for large portfolios, for people who genuinely want US-listed securities, and for retirees who will spend in US dollars.
If the total cost of your specified foreign property exceeds $100,000 CAD at any point in the year, you must file form T1135 with your return.
The details that matter:
The practical takeaway: if you hold US-listed securities in a taxable account and are approaching six figures of cost, know that this form exists and tell whoever prepares your return. It is a filing obligation people discover late, and the penalty is entirely avoidable.
Yes, and unlike in an RRSP you cannot recover it. The US withholds 15% of dividends paid to Canadian residents. The Canada–US treaty exempts RRSPs and RRIFs, and in a taxable account you can claim a foreign tax credit — but a TFSA generates no Canadian tax to credit it against, so the 15% is permanently lost. On a US ETF yielding 1.5%, that is roughly 0.22% a year.
It is a way to convert Canadian dollars to US dollars for almost nothing, instead of paying your broker roughly 1.5%. Buy DLR on the TSX in Canadian dollars, wait for settlement, ask your broker to journal the shares to the US-dollar listing DLR.U, then sell DLR.U for US dollars. Total cost is usually under $50 versus about $300 on a $20,000 conversion. Do not journal before the trade settles, and for amounts under a few thousand dollars it is generally not worth the effort.
When the total cost — not market value — of your specified foreign property exceeds $100,000 CAD at any point in the year. US-listed stocks and ETFs in a taxable account count; registered accounts such as RRSPs and TFSAs are entirely exempt, and Canadian-listed ETFs holding foreign stocks generally do not count. It is a disclosure form with no tax attached, but failing to file attracts penalties starting at $25 a day.
Model a sale of a US-listed holding. Because the gain must be computed in Canadian dollars at the exchange rate on each transaction date, currency movement alone can create a taxable gain on a position that went nowhere in US dollars.
