Can exchanging foreign currency create a Canadian capital gain?

Foreign currency itself can produce a gain or loss as exchange rates change. For capital transactions involving currency held personally, CRA applies a $200 annual net-gain-or-loss threshold. Business currency transactions follow a different analysis.

Distinguish currency from foreign investments

CRA says the reportable capital currency amount is the annual net gain or loss exceeding $200. That rule should not be used as a blanket exemption for gains on foreign stocks or property. Those assets require their own Canadian-dollar calculations.

When a foreign investment is sold, its proceeds and cost are converted using the relevant rates for their respective dates. Subtracting the original foreign-currency cost and converting only the difference can produce the wrong Canadian result.

Official guidance: [1], [2].

Keep a transaction history

For example, money held in a foreign-currency account may be converted back to Canadian dollars at a different rate from the acquisition rate. Record the original cost of the currency and the amount realized rather than relying only on the bank's latest exchange rate.

Gather the currency records

• Dates and Canadian-dollar costs of currency acquisitions.
• Conversion, spending, and disposal transactions.
• Fees and the exchange-rate source used.
• Separate records for business funds and investment sales.

Ask your preparer to identify which transactions are on capital account and whether the $200 rule applies. For frequent or complicated activity, establish a consistent recordkeeping method before year-end. A foreign account balance alone cannot reveal the realized gains and losses during the year.
