How does the USD/CAD exchange rate affect my investment returns?

When you hold USD-denominated assets in a Canadian account, your return in Canadian dollars depends on two separate factors: (1) the return of the underlying investment in USD, and (2) the movement of the USD/CAD exchange rate between when you bought and when you sold. If the USD strengthens against the CAD (USD buys more CAD), your CAD returns are increased by the currency movement. Example: you buy VTI at USD $200 when the exchange rate is 1 USD = 1.33 CAD. Your CAD cost is $266. VTI rises 10% to USD $220. You sell and convert to CAD at 1 USD = 1.40 CAD. Your sale proceeds = $220 × 1.40 = $308. Your total return = ($308 − $266) / $266 = 15.8% in CAD terms — even though the stock only returned 10% in USD. If the USD weakens (CAD strengthens): the reverse occurs. A 10% USD gain combined with a 5% USD depreciation produces only about 4.5% in CAD terms. Over long periods (10–20 years), currency effects have historically tended to average out, though in shorter periods they can dominate returns. CAD/USD range over the last 20+ years: approximately $0.63 (CAD low, 2002) to $1.10 (CAD parity, 2007–2011) to approximately $0.72–0.76 (2024–2025). Significant volatility has historically characterized this pair.

Does currency movement inside a TFSA or RRSP create a taxable event?

No — currency movements inside registered accounts (TFSA, RRSP, RRIF, LIRA, FHSA) do not trigger any taxable event. Here is why: investments inside a TFSA or RRSP are not "disposed of" for tax purposes when the exchange rate changes. CRA only taxes dispositions — actual sales of property. A change in the exchange rate with no sale is not a disposition. Furthermore: all income and growth inside TFSA is completely tax-free forever. All income and growth inside RRSP is tax-deferred until withdrawal. When you withdraw from an RRSP, the withdrawal is taxed as regular income in Canadian dollars — based on the CAD value of the amount at the time of withdrawal, not your original cost in either currency. There is no separate calculation of currency gain or loss. You can hold USD cash or USD-denominated securities inside a TFSA or RRSP, and conversion of USD to CAD inside those accounts is also not a taxable event — even if the exchange rate has moved since you deposited the funds. This is genuinely simpler than non-registered accounts (see below).

Does currency movement in a non-registered account create a taxable event?

Yes — in a non-registered (taxable) account, purchasing a foreign currency (e.g., USD) and later converting it back to CAD at a different rate constitutes a disposition of foreign currency property and may trigger a capital gain or loss under the Income Tax Act. Specifically: if you deposit CAD into a USD cash account at your broker (converting at 1 USD = 1.35 CAD), then later convert USD back to CAD when 1 USD = 1.40 CAD, you have realized a currency gain of 0.05 CAD per USD exchanged. This is a capital gain even if you never invested the USD in a security — simply holding USD cash in a non-registered account and converting it later is a taxable event if the rate moved. Exception: the Income Tax Act has a personal-use property exemption — if the foreign currency was for personal use (e.g., holding USD for travel, foreign tuition), gains under $200 are not taxable and losses are not deductible. For investors, this exemption does not protect speculative or investment-related foreign currency gains. Practical implication: investors who buy US stocks in a non-registered account must track their ACB (adjusted cost base) in Canadian dollars using the exchange rate on the date of purchase, not the date of sale. The gain or loss in non-registered is always measured in CAD at the time of each transaction.

How do I calculate my capital gain when I sell a US stock in a non-registered account?

Capital gains in non-registered on USD assets are always calculated in Canadian dollars. The formula: Capital gain (CAD) = Proceeds of disposition (CAD) − Adjusted cost base (CAD) − Selling costs (CAD). Step-by-step example: You buy 100 shares of VTI at USD $200/share. Exchange rate at purchase: 1 USD = 1.35 CAD. ACB = 100 × $200 × 1.35 = $27,000 CAD. Time passes. VTI rises to USD $250/share. Exchange rate at sale: 1 USD = 1.40 CAD. Proceeds = 100 × $250 × 1.40 = $35,000 CAD. Capital gain = $35,000 − $27,000 = $8,000 CAD. Of this $8,000 gain: approximately $3,500 is due to the stock rising in USD terms (converted at constant rate); approximately $4,500 would be roughly the stock return at original rate... but in practice you only track the total CAD gain — you do not separately calculate "currency gain" and "equity gain." The entire $8,000 capital gain is reported on Schedule 3 of your T1. The gain is split 50% capital gains inclusion, taxed at your marginal rate. Exchange rate to use: Bank of Canada noon spot rate on the transaction date is the standard. Some brokers provide the exact rate used on your trade confirmation.

Does it matter if I hold USD cash inside an RRSP?

Holding USD cash inside an RRSP is common — particularly after selling USD-denominated securities before buying new ones, or while waiting for a Norbert's Gambit conversion to settle. From a tax perspective: there is no taxable event for any currency movement, sale, or conversion inside the RRSP. From an investment perspective: USD cash inside an RRSP sits uninvested and earns little or no return (most brokers pay minimal interest on USD cash). Holding USD inside RRSP for administrative convenience (a few days between trades) is fine. Holding USD inside RRSP for months as a "strategic currency position" provides interest drag and opportunity cost. Some Canadian investors deliberately hold USD in RRSP as an informal currency hedge against CAD weakness — this is valid but should be conscious and intentional. One practical note: RBC Direct Investing, TD Direct Investing, and most major Canadian broker RRSPs support USD denomination inside the account. Questrade and Wealthsimple also support USD in RRSP. You do not need to convert back to CAD before year-end or any specific deadline.

How do I report USD investment income on my Canadian tax return?

All income on your Canadian T1 must be reported in Canadian dollars. USD income must be converted. Conversion rule: use the Bank of Canada exchange rate on the date the income was received (or, for convenience, the Bank of Canada annual average rate for the calendar year). CRA accepts either the daily rate on the transaction date or the annual average for the taxation year for most investment income. For dividends: your broker typically converts and reports CAD amounts on your T5 or T3 slip, so you use those amounts directly. For capital gains: you use the exchange rate on the purchase date for ACB, and the exchange rate on the sale date for proceeds. For interest: same as dividends — broker usually reports in CAD on slips. If you received USD distributions that were reported in USD (e.g., from a US brokerage): use the Bank of Canada average rate. Look up the annual average USD/CAD rate at the Bank of Canada website (bankofcanada.ca → Statistics → Exchange Rates → Annual averages). For 2024: approximately 1 USD = 1.3600 CAD. For 2023: approximately 1 USD = 1.3496 CAD.

Should I hold USD permanently in my investment accounts or always convert to CAD?

This depends on your investment strategy and account type. In registered accounts (RRSP, TFSA): you can hold USD permanently without any tax consequences for currency movement. Many investors keep a USD sub-account within their RRSP to hold US-listed ETFs without constantly converting. Each time you buy, you use USD. Each time you receive dividends, they accumulate in USD. This avoids repeated conversion costs. In non-registered accounts: maintaining USD is also operationally easier — you avoid triggering a currency disposition each time you convert back to CAD. Each sale of a USD security still triggers a capital gain/loss calculation in CAD, but holding USD between US stock purchases does not create repeated currency conversion events. For most Canadians whose ultimate spending currency is CAD (retirement, mortgages, living expenses): keeping permanent USD allocation adds currency risk. The standard advice from Canadian financial planners is to hold the percentage of your portfolio in USD that reflects your US equity allocation, and accept the currency volatility as part of long-term equity investing — while avoiding excessive USD cash accumulation beyond what is needed for imminent US investments.

ACB tracking: practical rules for non-registered

Record purchase date, USD price, and CAD exchange rate for every buy
ACB formula: shares × USD price × CAD rate = CAD ACB
Add to ACB on subsequent buys (average cost basis)
Reduce ACB proportionally on sell
Dividends reinvested (DRIP): each reinvestment is a new ACB lot — record separately
