Why a Weaker Canadian Dollar Makes U.S. Purchases Cost More

A weaker Canadian dollar means more Canadian dollars for each U.S. dollar. Learn the conversion, checkout caveats and broader effects on Canadian prices.

A U.S. price is charged in U.S. dollars, so a Canadian buyer needs more Canadian dollars to pay it when the Canadian dollar weakens. The direct conversion is simple: multiply the U.S. price by the transaction exchange rate quoted in Canadian dollars per U.S. dollar. Fees and the payment provider’s own rate can change the final charge.

How a weaker Canadian dollar raises the converted price

For a U.S.-priced item, the exchange rate tells you how many Canadian dollars are needed for each U.S. dollar. The quote convention matters: a higher figure in CAD per USD means the U.S. dollar costs more in Canadian currency.

Illustration only: If an item costs USD 100 and the applicable rate is CAD 1.30 per USD, its converted price is CAD 130 before fees. At a hypothetical rate of CAD 1.40 per USD, the same item converts to CAD 140. These are arithmetic examples, not current rates or an offer from a payment provider.

The Bank of Canada explains that a weaker dollar is bad for Canadians shopping or travelling abroad. The same U.S.-dollar price therefore takes more Canadian dollars to cover when the Canadian dollar loses value against the U.S. dollar. Bank of Canada: Understanding exchange rates

Why your final checkout amount may differ

The Bank of Canada describes its published exchange rates as indicative rates, calculated from averages of aggregated price quotes from financial institutions. They are useful as a reference for understanding or estimating a conversion, but they do not establish the rate or fees for an individual purchase. Bank of Canada exchange rates

Your actual Canadian-dollar charge depends on the payment provider’s transaction rate and terms. Check the rate and fees shown by your card issuer, bank or merchant before completing the purchase. A merchant may offer to convert the price into Canadian dollars; compare that offer with the terms your payment provider will apply rather than assuming either is the reference rate.

A U.S. sticker price and a Canadian shelf price are different

The conversion effect applies directly when you buy something priced in U.S. dollars. A Canadian retailer’s shelf price is a separate matter. A weaker Canadian dollar can make imported finished goods and imported production inputs cost more in Canadian dollars, but retailers and manufacturers do not necessarily pass those costs on immediately or in full.

How much and how quickly prices respond can depend on the product’s import content, demand, pricing decisions, the costs of changing prices and how long a business expects the currency move to last. Firms may absorb some cost increases to protect sales. As a result, Canadian goods do not all rise by the same percentage as the currency moves. The Bank of Canada discusses these factors in its analysis of exchange-rate pass-through. Bank of Canada: Exchange-rate pass-through

Statistics Canada examined import prices and the Canada–U.S. exchange rate from 2018 through 2022. It noted that their co-movement after the second quarter of 2021 may suggest that depreciation passed through to import prices. That observed relationship does not prove that currency changes alone caused every change in import prices. Statistics Canada: Import prices and the Canada–U.S. exchange rate

Why the exchange rate can affect Canadian retailers in more than one way

Currency movements affect retailers through both the cost of imports and shoppers’ willingness to buy across the border. A stronger Canadian dollar can lower the Canadian-dollar cost of imports while also making U.S. shopping more attractive to Canadians. Those forces can affect domestic retailers in different directions. A Bank of Canada working paper studies both channels. Bank of Canada Staff Working Paper 2019-34

For historical context, that 2019 paper reports that the Canadian exchange rate appreciated by 57% from 2002 to 2012. Its model estimated that the appreciation reduced the retail price index by 6.5%. These are model-based estimates for that period, not a forecast or a universal result for a given currency move. The authors also found estimates consistent with direct-importing retailers passing lower import costs through to prices, while retailers near the U.S. border faced sales pressure associated with greater cross-border shopping exposure.

How to compare buying in the U.S. with buying in Canada

To judge whether a U.S. purchase is cheaper, compare the full cost rather than the sticker prices alone:

What makes the Canadian dollar move

The foreign-exchange market determines the Canadian dollar’s value. The Bank of Canada lists relative interest rates, relative inflation, demand for financial assets, and demand for Canadian goods and services among factors that can affect it. Bank of Canada: Understanding exchange rates

Reasons for a particular move depend on the period. In an analysis published January 29, 2025, the Bank said the Canadian dollar had declined against the U.S. dollar since October 2024, mostly because of increased uncertainty about trade policies, with a modest contribution from a widening policy-interest-rate differential. That account describes developments at the time; it is not a current explanation of the exchange rate.
