Effective 20 July 2026, Mastercard's non-DCC cross-border assessment fee in Canada rose from 60 basis points to 100 basis points. If you sell to Canadian customers in a foreign currency, or process international card payments that route through Mastercard's cross-border rails, this fee increase is already showing up in your processing costs, whether or not anyone told you about it directly.
What actually changed
Before this change, the cross-border assessment fee in Canada depended on who performed the currency conversion: one rate applied when the merchant handled the foreign-exchange conversion, and a different rate applied when the card issuer did it instead. The previous non-DCC rates were 60 basis points in one case and 100 basis points in the other, depending on which party converted the currency.
The new rule, effective 20 July 2026, unifies the non-DCC cross-border assessment at 100 basis points regardless of whether the merchant or the issuer performs the conversion. In practice, this means transactions that previously qualified for the lower 60 basis-point rate now cost more, and there's no longer a way to structure the conversion process to land in the cheaper tier.
Why this is easy to miss
A 40 basis-point increase on a single transaction is small enough that most founders won't notice it looking at any one payment. It shows up as a change in the interchange or network-fee line of a processing statement, not as a headline cost. Both Checkout.com's documentation on commercial interchange changes and PayPal's Fall 2026 card network release guide describe this as part of a routine network fee update — the kind of change that's easy to scroll past in a processor's notification email.
The effect compounds at volume, though. A business doing meaningful transaction volume with Canadian customers, or with any international customers whose cards route through Mastercard's cross-border processing, is now paying a higher assessment fee on every one of those transactions than it was before 20 July 2026.
This particular change is specific to Canada and to Mastercard's non-DCC cross-border assessment. It doesn't automatically mean every network or every country moved in the same direction, so don't assume Visa's Canadian cross-border pricing or Mastercard's rates elsewhere changed on the same schedule. Treat this as a prompt to check your actual statements rather than a reason to assume your overall international processing costs moved by exactly 40 basis points.
What to actually check
Pull your processing statements from before and after 20 July 2026 and compare the cross-border or international assessment fee line specifically. If your processor passes network fees through directly, on interchange-plus or similar pricing, you should be able to see the increase reflected transaction by transaction. If you're on a blended rate, the increase may be absorbed into your processor's overall rate rather than itemised, in which case ask your processor directly whether and how this Mastercard change has affected your effective rate on Canadian or foreign-currency transactions.
Once you know the actual cost impact, factor the higher rate into margin calculations specifically for Canadian sales or any other foreign-currency transactions that route through Mastercard, rather than assuming your blended average processing cost still applies evenly across all transaction types.
Does pricing in local currency help
Because the fee applies to cross-border transactions specifically, one lever worth considering is whether pricing in the customer's local currency reduces how many of your transactions get classified as cross-border in the first place, and reduces reliance on dynamic currency conversion. This won't eliminate cross-border fees for a genuinely international customer base, but it's worth checking with your processor whether local-currency pricing changes your fee exposure under the new unified rate, given that the old distinction between merchant-converted and issuer-converted transactions no longer creates a cheaper tier to aim for.
The bottom line
Mastercard's non-DCC cross-border assessment fee in Canada moved to a unified 100 basis points on 20 July 2026, up from a previous range of 60 to 100 basis points depending on who converted the currency. Check your processing statements for the change now, factor the higher rate into margins on Canadian and foreign-currency sales, and ask your processor whether local-currency pricing changes your exposure under the new rule.
