Accepting payments in Canada. 7 chapters and a final quiz.

Chapter 1. Scoping the rail: five questions before you call a provider.

A merchant entering Canada often starts by picking a provider. That is the wrong order, because the country stacks two markets with different rails and different costs. On the consumer side, credit cards account for 33% of volume but 6% of value. On the business side, EFT bulk transfers account for 14% of volume and 63% of value (Payments Canada, Canadian Payment Methods and Trends, 2025 edition, 2024 data). Choose the rail first. Then choose the provider, based on its ability to connect to that rail.

Chapter 2. Interac Debit: reading the rate card and routing to capture it.

Interac Corp. publishes its fee schedule in more detail than almost any other scheme. A payments manager can therefore calculate what their mix will cost in interchange before any negotiation starts. The result surprises teams from ad valorem markets: on domestic card-present debit, interchange is measured in fractions of a cent, not in percentage points.

AVERAGE TICKET                               C$48.00
TRANSACTIONS IN THE MONTH                     40,000
VOLUME                                   C$1,920,000

PATH A — Interac Debit contactless, tier 3
  40,000 x C$0.035                      =     C$1,400
  i.e.                                        0.073%
  (Interac Corp., 2026 rate card: tier 3 =
   all other merchants, C$0.01 to C$100.00)

PATH B — Interac Debit online (in-app/browser)
  C$1,920,000 x 0.60%                   =    C$11,520
  (default tier 1; the C$1.80 cap
   above C$300 has no effect here)

PATH C — credit card, merchant below the
small-business commitment thresholds
  C$1,920,000 x 0.95%                   =    C$18,240
  (Department of Finance Canada, commitments
   in force since October 19, 2024)

GAP A vs C, IN A SINGLE MONTH           =    C$16,840

WHAT THIS CALCULATION LEAVES OUT
  Interac switch fees: C$0.013985 per
  transaction, rising to C$0.014438 on November 1,
  2026; online acquirer service fee: C$0.025;
  and your acquirer’s own fee, which is negotiable.

That leaves routing, the most common leak. On a card that carries Interac and an international application, the cardholder chooses the application, not the terminal. The rule comes from element 9 of the Code of Conduct, which covers competing debit applications. A misconfigured terminal, or a checkout that presents the international application first, quietly shifts your mix to the more expensive rate card. Checking is easy. Pay in store yourself with a debit card from a major Canadian bank, and see what the screen offers first.

Chapter 3. Credit cards: cost, surcharging, and the Code of Conduct.

Canada has no statutory interchange cap. Instead, it has voluntary commitments from Visa and Mastercard, secured by the Department of Finance under the threat of regulation and limited by a revenue threshold above which they do nothing. The most useful day-to-day tool is therefore not about price. The Code of Conduct for the Payment Card Industry in Canada is administered by the Financial Consumer Agency of Canada (FCAC). It sets no prices. It sets deadlines, and deadlines become negotiating leverage.

• Element 1: transparency of the merchant application, the merchant agreement, and the monthly statement. The statement is your only proof of cost, so insist that it be readable before you sign.
• Element 3: penalty-free termination after an unfavorable change. It is the counterpart to the notice requirement, and it expires.
• Element 4: notice of fee changes, from the acquirer to the merchant.
• Element 5: limited acceptance. Accepting credit but not debit, or the reverse, is your choice.
• Element 6: no negative-option acceptance. A new product is not added to your contract by default.
• Element 7: rules on renewing merchant agreements and related services.
• Element 8: discounts by payment method. This is the legal basis for a lower price for debit or cash.
• Element 9: competing debit applications. On a card carrying Interac and an international application, the cardholder chooses.
• Element 12: premium cards. They cannot be quietly imposed on the merchant.
• Element 13: card identification, so checkout staff can tell which product is being presented.

Chapter 4. Choosing an acquirer and reading the contract.

Canadian acquiring is concentrated and bank-owned. The country’s largest acquirer, Moneris, is a joint venture owned equally by Royal Bank of Canada and Bank of Montreal. Interac Corp. publishes the list of acquirers authorized to offer its point-of-sale debit service, which gives merchants a clean filter. A provider not on that list cannot give you direct Interac Debit acceptance. It will go through a third party, which will sit in your contract chain without ever appearing in your RFP.

Chapter 5. e-Transfer, pre-authorized debit, and the Real-Time Rail.

Two thirds of the value of Canadian payments moves not by card but by bulk transfer through the AFT, which carries payroll, benefits, and direct debits. A software vendor or biller that has built only card payments covers 6% of the market’s value. Three instruments share the rest, and they are not interchangeable. The first collects, the second runs mandates, and the third is still on its way.

• Autodeposit: the payee’s alias is linked to an account in advance, so funds are credited automatically and the security question goes away. Ask your business customers to turn it on; it removes the main interception risk.
• Request Money: the payee initiates and the payer approves in their banking app. It is the closest thing to request-to-pay available in Canada today.
• Business version: higher limits, bulk payouts for payroll and suppliers, and richer reconciliation data. Without that data, cash application is done by hand.
• Limits: each issuing institution sets its own, not the scheme. Your flow has to cope with a block you can neither see in advance nor query.
• Direct participation: limited to regulated entities. A nonbank provider must be registered under the RPAA and registered as a money services business with FINTRAC.
• Indirect connection: an indirect participant connects through an approved connection service provider. Interac publishes the list, which includes Central 1, Desjardins, Peoples Trust Company, and Digital Commerce Bank.

Chapter 6. Sales taxes: one federal, several provincial, one checkout.

Canadian sales tax is based on the customer’s address, not the seller’s: a merchant in Alberta shipping to Halifax charges the Nova Scotia rate. Three regimes coexist, each with its own administrator and its own return. Configuration is therefore done province by province, never at the account level. A setup error does not show at the point of sale; it shows at the first tax audit.

WHAT THE PAYMENT ENGINE MUST REMEMBER
  the authorized amount is the TOTAL, not the
  displayed price; a partial refund reverses tax
  at the rate of the original sale, not today’s rate.

• Business number and GST/HST account. The small supplier threshold is C$30,000 in taxable sales; above it, registration is no longer optional.
• Simplified regime for non-residents, in effect since July 1, 2021, for digital products and services sold to Canadian consumers above C$30,000 over 12 months. The trade-off: it gives no right to input tax credits (Canada Revenue Agency).
• QST registration with Revenu Québec, under the specified registration system for suppliers outside Quebec, above the same C$30,000 threshold. The number issued carries the prefix NR.
• Separate provincial registrations in British Columbia, Saskatchewan, and Manitoba, each with its own province and its own filing calendar.
• A province-to-rate lookup table in the tax engine, driven by the shipping or billing address and reviewed whenever a change is announced.

Chapter 7. Quebec: language, signage, and surcharging.

Quebec is not a marketing variant of the Canadian market. It has a distinct regime on three issues that directly affect payment acceptance: the language of contracts, signage, and surcharging. A Canada-wide rollout that treats Quebec like any other province creates three compliance failures at once, none of which shows up in technical acceptance testing. All three show up in an inspection.

• Inventory every surface before you translate: payment page, terminal screens, receipt, confirmation email, pre-authorized debit notice, refund policy, complaint flow.
• Set language at the order level, not the account level. A Quebec customer of an Ontario merchant is still a Quebec customer.
• Make the surcharge conditional on the billing province, and test the Quebec case before going live.
• Open both Revenu Québec files alongside the federal one: QST registration and, if your business requires it, the money services business license.
• Date your templates. The June 1, 2025, signage requirement covers physical and software media that product teams do not naturally think of as commercial signage.
