Reporting USD trades on your Canadian return

Every US-dollar buy, sell, and outlay must be converted to CAD at its applicable transaction time. Here is how to build and retain that evidence.

Key takeaways
  • Convert proceeds when sold, ACB when acquired, and outlays when incurred, using a documented and verifiable rate source.
  • You report in CAD even if you never converted the US dollars back.
  • Currency movement between buy and sell is part of your capital gain or loss.

The rule: convert each amount when it arises

The CRA requires amounts on your return to be reported in Canadian dollars. Its capital-gains guidance says to convert proceeds at the exchange rate in effect when you sold, adjusted cost base when you acquired, and outlays and expenses when incurred.

Use a consistent, verifiable source and retain the exact rate, source, and applicable date. The Bank of Canada is generally accepted; another source may also be accepted if it is widely available, verifiable, published by an independent provider, and used consistently.

Sched3's securities ledger uses the recorded trade date for acquisitions and dispositions and preserves settlement date separately as broker evidence.

Where to find the rate

The Bank of Canada publishes daily exchange rates at bankofcanada.ca/rates/exchange/daily-exchange-rates/. The specific series is FXUSDCAD — the number of Canadian dollars per one US dollar.

Look up the observation required by your documented transaction-date methodology. If no observation exists for that date, document the consistent fallback used.

Sched3 stores the recorded rate, applicable date, and source. It blocks filing readiness when that provenance is missing.

Buying in USD: your ACB in CAD

When you buy a US stock, your adjusted cost base is recorded in Canadian dollars:

ACB (CAD) = (USD purchase price x units + USD commission) x BoC rate on applicable transaction date

This CAD figure is what gets pooled with your other holdings of the same security and becomes the cost base you subtract from proceeds when you eventually sell.

Example. Buy 100 shares of AAPL at US$180, commission US$5. Settlement date BoC rate: 1.3550.
ACB = (180 x 100 + 5) x 1.3550 = $24,396.78 CAD

Selling in USD: your proceeds in CAD

When you sell, your proceeds of disposition are also converted to CAD at the BoC rate on the sell applicable transaction date:

Proceeds (CAD) = (USD sale price x units - USD commission) x BoC rate on sell applicable transaction date

Your capital gain or loss is then: Proceeds (CAD) - ACB (CAD) - outlays

Note that even if the stock price in USD didn't move, you can still have a capital gain or loss in CAD due to exchange rate movement between the buy date and sell date.

FX gain/loss on the currency itself

If you hold US dollars in your brokerage account (for example, after selling a US stock and before buying another), the USD itself is considered property. Converting it back to CAD at a different rate than you acquired it creates a capital gain or loss on the currency.

In practice, the CRA provides a $200 annual exemption on FX gains from personal transactions. Most investors with small USD balances won't exceed this, but active traders or those holding large USD cash positions should be aware.

When the FX gain/loss is embedded in a stock transaction (you buy and sell a US stock), it is already captured in the CAD proceeds-minus-ACB calculation — no separate reporting needed.

Dividends in USD

US-dollar dividends also need to be converted to CAD. However, your broker's T5 or T3 slip usually reports the Canadian-dollar equivalent already (they convert at their own rate, which the CRA accepts if it's a Canadian financial institution).

If you receive a foreign income slip or your broker doesn't convert, use the BoC rate on the dividend payment date.

US withholding tax (typically 15% on dividends in a non-registered or TFSA account) is also reported in CAD on your return, and claimed as a foreign tax credit on form T2209.

Common mistakes

  • Applying one annual average indiscriminately — Acquisitions, dispositions, and outlays arise at different times and need their applicable conversions.
  • Leaving the date methodology implicit — Record the exact date the ledger uses and keep settlement date separately as source evidence.
  • Using an undocumented broker rate — A broker rate may be usable, but retain evidence that makes the source and methodology verifiable.
  • Forgetting the FX component of the gain — If USD strengthened between your buy and sell, part of your gain in CAD is currency appreciation, not stock appreciation. Both are taxable.
  • Double-converting — If your broker slip already shows CAD amounts, converting again would be incorrect. Check the currency on your T5008.

Frequently asked

Can I use an annual average exchange rate for my US stock trades?

Do not apply one average indiscriminately to separate acquisitions, dispositions, and outlays. Convert each amount when it arises and document the consistent source and methodology used.

What exchange rate does the CRA accept?

The Bank of Canada is generally accepted. CRA may also accept another widely available, verifiable, independently published source used consistently. Retain the exact rate, applicable date, and source.

Do I report the gain in CAD even if I never converted the USD back?

Yes. All amounts on your Canadian tax return are in CAD. The conversion for reporting purposes is notional — you convert each transaction to CAD for the calculation, regardless of whether you actually exchanged currency.

My broker T5008 already shows CAD amounts — do I need to reconvert?

If your Canadian broker's T5008 shows amounts in CAD, they've already converted for you. Verify the amounts look reasonable, but don't convert again. If the slip shows USD (some IBKR slips do), you need to convert to CAD yourself.
