If you run a business in Canada, you already know that accepting card payments isn't free. But the real cost of payment processing is buried under layers of interchange fees, assessment fees, and processor markups. In this guide, we break down exactly what Canadian merchants pay — and how to keep those costs under control.
Understanding Interchange Fees
Interchange fees are set by the card networks — Visa, Mastercard, and Interac — and paid by the merchant's bank to the cardholder's bank every time a transaction is processed. In Canada, these typically range from 1.4% to 2.4% for credit cards, while Interac Debit sits at a flat fee of $0.01 to $0.07 per transaction.
Comparing Payment Methods
Not all payment methods cost the same. Here's how the most common options stack up for Canadian businesses:
- Interac Debit: $0.01–$0.07 per transaction — the cheapest option by far
- Visa credit: 1.4%–2.4% plus a per-transaction fee of $0.05–$0.10
- Mastercard credit: 1.4%–2.4% plus a per-transaction fee of $0.05–$0.10
- American Express: 2.0%–3.5% — the most expensive card network for merchants
Hidden Costs to Watch For
Beyond interchange, many processors tack on monthly fees, PCI compliance fees, batch processing fees, and chargeback fees. These can add $30–$100+ per month to your total cost of payment processing in Canada, especially if you're on a tiered pricing model instead of interchange-plus.
How to Reduce Your Processing Costs
The single most impactful step is to switch to interchange-plus pricing. This model passes through the actual interchange rate and adds a fixed, transparent markup — unlike tiered pricing which bundles transactions into opaque rate categories.
- Negotiate rates once you exceed $10,000/month in volume
- Encourage Interac Debit for in-store transactions
- Review your monthly statement for unnecessary add-on fees
Bottom Line
Payment processing cost in Canada varies widely based on your provider, pricing model, and transaction mix. Most small businesses pay between 1.5% and 3.0% of their card revenue in processing fees. By choosing interchange-plus pricing and encouraging debit, you can bring that number closer to 1.5% — saving thousands of dollars per year.
