Best credit card processing for small business in Canada

The best credit card processing for a small business in Canada takes Interac Debit and credit cards by chip and by tap, shows you what each card really costs, and lets you leave without a penalty if the service slips. Clearo Payments publishes this list and ranks itself first for the criteria below; what we say about the others comes from their own pages.

Both kinds of card matter at a Canadian till. Per Payments Canada, credit cards accounted for 43% of all payment transactions in Canada in 2025, and debit cards for 25%. Whichever processor you pick has to handle both, at a price you can follow line by line. Our page on merchant services for Canadian and US businesses explains how we price each.

How we chose the best credit card processing for small business in Canada

We scored each company on five criteria: the first four describe how Clearo works, which is why it ranks first, and the fifth is about the counter itself. The others follow in order of how closely their own pages match.

1. Pricing you can check. With interchange-plus pricing, the card network's cost and the processor's margin appear as separate lines, so you can see what each card costs you.
2. Terms you can leave. No long-term contract and no cancellation fee, so switching stays a real option.
3. A named person to call. A dedicated rep for every client, so you always know who to ask.
4. Proof before you switch. A free statement review that shows what you pay now and what the same month would cost.
5. Fit for in-person sales. Interac Debit by chip and PIN or tap, Visa and Mastercard credit, phones and watches, and help with the surcharge rules where you sell.

Some businesses should weigh these differently. If you want POS software with inventory, menus or appointment booking from the same company that processes your cards, look at Square, Clover and Global Payments below. If you'd like your processing to come through your bank, TD Merchant Solutions offers the Clover platform in Canada. And if you take only a few card payments a month, one rate on every sale may be easier to live with than an itemized statement, which is the idea behind the Moneris Flat Rate plan.

1. Clearo Payments

Clearo Payments provides payment processing and merchant accounts for businesses in Canada and the US, and its terminals accept Interac Debit alongside credit cards and mobile wallets.

Why Clearo ranks first

Clearo meets all four core criteria. Pricing is interchange-plus, so you can check what each card costs you. There's no long-term contract and no cancellation fee, so you can leave if the service slips. Every client gets a dedicated rep, so you always know who to call. And the free statement review shows what you'd pay before you move anything. For a Canadian counter, that comes with terminals that take Interac Debit by chip and PIN or by tap.

How the pricing works

Interchange-plus splits the cost of each card payment into two parts. The first is what the card networks set: interchange, paid to the bank that issued your customer's card, plus the networks' own fees. That part passes through at cost and shows on your statement as its own lines. The second is Clearo's margin, which sits on a separate line. Because the two never blend into one rate, you can check the network side against the networks' published interchange schedules and see exactly what we add on top. When the networks lower interchange, as they did for qualifying small businesses in 2024, the cut reaches your statement without anyone renegotiating.

What you get

Our POS terminals read chip, tap and swipe, accept Interac, Visa, Mastercard, Apple Pay and Google Pay, and come in countertop, wireless and portable models. Mobile payments add tap to pay and mobile card readers for sales away from the till, such as a market stall or a delivery. Outside Quebec, our surcharging program handles compliance, disclosure and setup if you choose to pass card costs on. You also get PCI compliance support, chargeback management tools, and same-day or next-day funding options.

Switching to Clearo

Switching starts with the free statement review: send a recent statement and we'll show your effective rate today and what the same month would cost with Clearo. Based on its client records, Clearo says businesses moving from flat-rate pricing have saved 20 to 50% on processing costs. Your own result depends on your card mix, your average sale and your volume, which is why the review comes before any decision. There's no long-term contract to sign and no cancellation fee if you leave later, and every client has a dedicated rep. Clearo says setup takes under 48 hours.

How to choose credit card processing for a small business in Canada

Start with how your customers pay, then read the contract as closely as the rate. Put these questions to every processor:

1. Which cards and wallets will the terminal take? Look for Interac Debit by chip and PIN and by tap, Visa and Mastercard credit, Apple Pay and Google Pay. Interac says that to take Interac Debit, a business has to connect with an acquirer, which in practice means a processor.
2. Is every fee in writing? The Code of Conduct for the Payment Card Industry in Canada requires a cover page on merchant agreements that include card processing, and statements at least monthly showing interchange, network fees and all other fees.
3. Are you buying, renting or leasing the terminal? Under the Code, the agreement's summary has to say which, with the terminal's fees, end date and termination fees. Our guide to choosing a debit machine runs the lease math.
4. How does it renew? FCAC's summary of merchant rights says you can give notice of non-renewal at least 45 days before renewal, and a fixed term can only renew automatically for six months or less.
5. What if fees go up? Under the Code you get 30 to 60 calendar days' notice of a new or higher fee, and you can leave without penalty within 70 calendar days after it takes effect.
6. Will network rate cuts reach you? The Code requires processors to tell eligible businesses if network fee reductions won't be passed on in full.
7. When does the money land, and do weekends and holidays change that?

Interac Debit at the counter

Interac Debit is priced differently from credit. Interac says it offers a single flat fee regardless of purchase price, while credit card interchange is a percentage of the sale, so the bigger the ticket, the more a debit payment saves you. It also says there are zero chargebacks with Interac Debit.

Taps have a ceiling: Interac contactless transactions are set at up to $250, with each bank or credit union choosing its own limit, so keep a terminal that takes chip and PIN. Interac also says businesses can take its contactless payments directly on a smartphone, a handy backup at a market stall. Our guide to tap to pay in Canada has the details.

Surcharges: the national cap and Quebec's ban

Outside Quebec, you can surcharge credit cards within limits. Since October 6, 2022, Visa has let Canadian merchants surcharge credit cards up to their merchant discount rate, with an absolute cap of 2.4%, after 30 days' written notice to the acquirer, according to Visa Canada. Mastercard's Canadian rules also cap surcharges at 2.4% and require notice to both Mastercard and your acquirer. Neither network allows a surcharge on its debit or prepaid cards, and Interac's fee page says merchants may not directly apply a surcharge for the use of Interac Debit.

Quebec is different. The Office de la protection du consommateur says merchants may not charge consumers any fee for paying by debit or credit card, and telling the customer first doesn't make it legal. If you sell in Quebec, leave surcharging off. Our guide to the credit card surcharge in Canada covers the rules in full.

What does credit card processing cost a small business in Canada?

Every card payment carries three layers of cost: interchange, paid to the bank that issued the card; the networks' own fees; and your processor's markup and monthly fees. Only the third varies between processors, so that's the one to shop on.

Processors package those layers in three common ways:

• Interchange-plus: network costs at cost plus a stated markup, each on its own line.
• Flat rate: one rate on every sale, whatever the card. Easy to predict, but the processor's share stays invisible.
• Tiered or blended: sales sorted into buckets with different rates, which makes the real cost hard to check. Our comparison of interchange-plus vs flat rate walks through the trade-offs.

The small-business interchange program changes the math. The federal government's agreements with Visa and Mastercard have lowered interchange for qualifying small businesses since October 19, 2024, and Finance Canada says more than 90% of businesses that accept credit cards would see interchange reduced by up to 27%. Eligibility is set network by network: annual Visa sales below $300,000 and annual Mastercard sales below $175,000. Visa's notice of upcoming interchange changes raises its threshold to $750,000 in annual Visa volume on October 24, 2026.

A worked example

Say a hardware store in Winnipeg takes $45,000 a month on credit cards and pays $1,170 in total fees, an effective rate of 2.6%. On an interchange-plus statement, that $1,170 splits into interchange and network fees on one side and the processor's share on the other. If the first part came to $830, the processor's share would be $340, and $340 is the number to compare between quotes.

Now say $400,000 of the store's yearly card sales are on Visa: over the old $300,000 line, under the new $750,000 one, so from October 24, 2026 those sales can qualify for Visa's small-merchant rates. On interchange-plus pricing the cut shows up on the next statement; on a flat rate, nothing changes unless the processor lowers the rate.
