Understanding how the Canada Revenue Agency (CRA) treats currency fluctuations is critical for any investor moving significant capital between CAD and USD. Ignorance of the $200 exemption rule or capital gains treatment can lead to unexpected liabilities during tax season.
Back in 2018, I worked with a client named Robert who had recently sold a property in Florida. He brought back about $300,000 USD and decided to sit on it in a high-interest savings account while waiting for the Canadian dollar to weaken. He eventually converted it when the loonie dipped, netting himself an extra $12,000 CAD purely from the exchange rate movement. Robert thought he was just being a savvy investor, but when April rolled around, his accountant dropped a bombshell.
«— Robert, you realize this $12,000 isn't just "found money," right? The CRA views this as a taxable capital gain,» his accountant told him. Robert was stunned because he hadn't actually "invested" in a business or a stock; he had just held cash. But in the eyes of the Canadian tax man, foreign currency is treated as a commodity, much like a piece of gold or a share in a company.
He ended up owing a significant portion of that gain back in taxes because he hadn't tracked his Adjusted Cost Base (ACB) from the moment the USD entered his possession. This story is common among Canadians who move between currencies without realizing that every conversion—and even just holding the currency—can trigger a "disposition" for tax purposes. If you are using methods like the Norbert Gambit, these calculations become even more vital to your bottom line.
The CRA provides a small relief for individuals. The first $200 of net realized foreign exchange gains or losses per year is exempt from taxation. This is designed to prevent every tourist from having to report the few dollars they made on leftover vacation cash.
Compare Bank RatesFor most investors, currency gains are treated as Capital Gains (only 50% is taxable). However, if you trade frequently or "flip" currencies as a primary source of income, the CRA may classify your profits as 100% taxable Business Income.
Trading Platform GuideIf you hold "Specified Foreign Property" (including cash in a US bank account) with a total cost exceeding $100,000 CAD at any point in the year, you must file form T1135. Failure to do so carries a penalty of $25 per day.
Reporting Forms«The biggest mistake I see isn't the tax itself, but the lack of records. By the time the CRA asks for the exchange rate on a Tuesday three years ago, most people have long forgotten where they even did the trade.»

To report correctly, you must convert all foreign currency transactions into Canadian dollars using the exchange rate in effect on the day of the transaction. The CRA generally accepts rates from the Bank of Canada. If you have multiple transactions, you can sometimes use the average annual exchange rate, but only if the transactions occurred evenly throughout the year.
Identify the date of acquisition and the date of disposition (conversion or spending).
Determine the CAD value at both points using Bank of Canada daily noon rates.
Subtract the $200 exemption from your total annual net gain.
Technically, yes. If you bought USD at 1.25 and spent it when the rate was 1.35, you realized a gain. However, the $200 annual exemption usually covers most personal travel expenses. It only becomes a major issue for high-value purchases like cars or international property.
Foreign exchange losses are treated as capital losses. They can be used to offset other capital gains, but they cannot be used to offset regular employment income. Just like gains, the first $200 of loss is ignored by the CRA.
Yes, foreign exchange gains within registered accounts like RRSPs, TFSAs, and FHSAs are generally not taxable. This makes them excellent vehicles for holding USD-denominated assets. For more details, see our guide on Holding USD Assets in RRSP and TFSA.
