Statistics Canada’s June trade release, published Tuesday, carried a line easy to skip past on the way to the headline trade balance. The average value of the Canadian dollar fell 1.7 cents US in June compared with May, the largest monthly decline since October 2022.
The Bank of Canada’s own monthly average series confirms the shape of the move and extends it: the loonie averaged 70.89 cents US in July, softer again than June, and down from 73.25 cents in February. That is a decline of roughly 2.4 cents across five months, most of it concentrated in the June drop StatCan flagged.
The Move in the Data Advisors Are Not Watching
Nobody tracks a monthly average exchange rate the way they track the TSX close. It has no ticker, no daily print, no chart on a client’s banking app. That is precisely why it is worth a deliberate look now.

A client who has been converting CAD to USD steadily through 2026, whether to fund a US brokerage account, cover cross-border spending, or build a corporate USD operating balance, has been doing so at a meaningfully less favourable rate in June and July than in February through May. That has two direct tax consequences, and they are not the same consequence.
Two Different CRA Rules, Not One
Subsection 39(2) of the Income Tax Act governs foreign exchange gains and losses realised on capital account. For individuals, the first $200 CAD of a net annual foreign exchange gain or loss is exempt. This exemption applies specifically to gains and losses arising from currency conversion itself: converting CAD to USD and back, or using USD cash to make a purchase or payment.
It does not apply to foreign exchange embedded in the sale of a foreign-denominated security. When a client sells a US-listed stock held in a non-registered account, the capital gain or loss is calculated by converting both the proceeds and the adjusted cost base to CAD at their respective transaction dates, and the resulting figure, currency movement included, is a single capital gain or loss with no $200 threshold attached. Advisors who apply the cash-conversion exemption to a securities disposition are applying a rule that does not reach that transaction.
What Non-Registered and Corporate Accounts Owe That Registered Accounts Do Not
Account type determines whether any of this matters at all. Inside an RRSP, RRIF, TFSA, or FHSA, currency movement has no personal tax consequence, since income and gains inside these accounts are sheltered or tax-deferred regardless of what the loonie does. The exposure sits entirely in non-registered personal accounts and in corporate investment or operating accounts.
For a CCPC holding US-dollar operating cash or a US-denominated investment account, the $200 exemption does not apply at all. Subsection 39(2)’s de minimis threshold is written for individuals. A corporation realises a foreign exchange gain or loss on every dollar of movement between acquisition and disposition, with no floor, taxed at the standard capital gains inclusion rate of 50 percent, unchanged after the 2024 proposal to raise it was cancelled in March 2025.
The T1135 Threshold Moves With the Rate, Not Against It
Form T1135 requires Canadian resident individuals, corporations, and certain trusts to report specified foreign property once its total cost amount exceeds $100,000 CAD at any point in the year. For property acquired in US dollars, that cost amount is the CAD value at the exchange rate on the date of acquisition, translated once and left alone. A weaker loonie today does not retroactively raise the CAD cost amount of a US holding bought in February at 73.25 cents.
What it does change is the arithmetic on every new purchase made from June onward. A client contributing the same number of US dollars to a US brokerage account in July converted at 70.89 cents rather than February’s 73.25, meaning the same USD contribution now books a larger CAD cost amount than it would have five months earlier. For a client dollar-cost-averaging into US equities through the back half of 2026, the cumulative T1135 threshold arrives sooner in USD terms than it would have in the spring, purely on the strength of the rate at which each contribution was converted.
The Planning Bridge Is Timing, Not Waiting
None of this is urgent in the sense of a filing deadline. It is urgent in the sense that adjusted cost base is a running total, tracked transaction by transaction at the settlement date, and a five-month gap in a client’s USD account activity is a five-month gap in the ACB record that has to be reconstructed later, usually during tax season, usually under time pressure, and usually from incomplete brokerage statements.
The advisors best positioned this fall are the ones who pull the USD account activity for clients likely to be affected now, while June and July’s conversions are still fresh in the client’s memory and the brokerage records are current, rather than waiting for a T3 or T5 slip to surface the question in March.
