How Payment Processing Fees Work in Canada

Canadian merchants typically pay fees in one of two pricing models:

The interchange rate is what Visa and Mastercard charge โ€” it varies by card type (credit vs. debit, rewards vs. basic, consumer vs. corporate). In Canada, typical interchange rates are:

Hidden Fees to Watch For

The advertised rate is just part of the picture. Watch for these additional fees when comparing Canadian payment processors:

When Flat-Rate Beats Interchange-Plus

Flat-rate pricing (Square, Stripe) isn't always more expensive. It can be better when:

Rule of Thumb: Once you're consistently processing over $5,000/month, interchange-plus pricing (Helcim) typically saves money. Under $2,000/month, flat-rate (Square, Stripe) is simpler and often comparable in total cost.

Interac Debit Fees

Interac debit fees are often significantly cheaper than credit card fees, which is why Canadian businesses should actively encourage Interac payments:

For businesses with high average ticket sizes (over $100), the difference between a 2.6% credit card fee and a $0.10 Interac fee can be substantial โ€” $2.50 vs. $0.10 on a $100 transaction.

Bottom Line

For most Canadian businesses, Helcim is the cheapest option once you pass $5,000/month in volume. Below that, Square or Stripe offer simplicity that may be worth the small premium. Whatever you choose, avoid long-term contracts with termination fees unless you're certain about the provider.
