Interac and Payment Methods for Online Stores in Canada

Canadian online shoppers mostly pay with credit cards, digital wallets such as Apple Pay and Google Pay, and PayPal, while Interac, Canada's debit network, is trusted for everyday debit payments and e-Transfers. A Canadian online store should price in Canadian dollars, charge the correct GST/HST and provincial taxes, and offer the payment methods its customers already use. Here is how each part fits.

Key takeaways

• Cards and digital wallets are the core of a Canadian checkout.
• Interac is very popular, but online support for Interac debit depends on your payment processor.
• Interac e-Transfer can work for small or custom orders, but it is manual.
• Show prices in CAD and calculate taxes based on the customer's province.
• Confirm tax registration with a Canadian accountant; this is general information.

Payment methods Canadians expect

• Credit cards: Visa and Mastercard are widely used, and many shoppers also carry Amex.
• Digital wallets: Apple Pay and Google Pay make mobile checkout fast.
• PayPal: familiar to many online shoppers.
• Buy now, pay later: options such as Affirm and Klarna for higher-value orders.
• Interac: the debit network most Canadians use in person.

Where Interac fits online

Interac is part of daily life in Canada, so shoppers trust the name. Online, there are two common uses:

• Interac debit at checkout: offered by some Canadian payment processors. Ask your processor whether it supports online Interac payments for your business type.
• Interac e-Transfer: the customer sends money by email or phone number. Small sellers sometimes accept it for custom orders, but it must be matched and confirmed manually, like a bank transfer.

For most stores, a reliable card and wallet checkout comes first, and Interac options are added where the processor supports them. If you are still choosing a platform, our comparison of Shopify, WooCommerce and custom stores shows how each one handles payment options and integrations.

GST/HST and provincial taxes in simple terms

Canada has a federal Goods and Services Tax (GST). Some provinces combine it with their own tax into a Harmonized Sales Tax (HST). Others charge a separate provincial tax, such as QST in Quebec or PST in British Columbia, Saskatchewan and Manitoba. The rate a customer pays usually depends on the province where the order is delivered. Small businesses below the "small supplier" threshold (generally $30,000 in taxable sales over four consecutive calendar quarters) may not need to register for GST/HST, but rules change and some sellers, including many non-resident digital sellers, have separate obligations. Check with the Canada Revenue Agency or an accountant.

In practice, your store should calculate tax from the delivery address, show it clearly before payment, and print it on the invoice. Most platforms can do this once the tax settings are configured correctly; a custom store needs the same rules built in.

Choosing a payment processor

The processor is the company that actually takes the card or wallet payment and sends the money to your bank. When comparing options, ask each one:

• Does it support a Canadian business account and payouts in CAD?
• Which methods are included: cards, Apple Pay, Google Pay, Interac online, buy now pay later?
• What are the fees per transaction, for currency conversion and for refunds and chargebacks?
• How long do payouts take, and are there holds on new accounts?
• Does it connect to your platform without custom work, and does it support 3-D Secure fraud checks?

Get the answers in writing and read the current terms on the processor's website, because fees and supported methods change.

Pricing, shipping and language

• Show prices in CAD; showing US dollars to Canadian shoppers reduces trust.
• Be clear about duties if you ship from outside Canada. Surprise charges at the door lead to refused parcels.
• Show realistic delivery times. Canada is large, and remote areas take longer.
• Publish a clear return policy and say who pays for return shipping.
• If you sell in Quebec, French is required for the website, checkout and order emails, so plan the French version from the start.

A checkout checklist for Canada

1. Prices in CAD across the store, cart and emails.
2. Postal codes in the Canadian format (A1A 1A1) and all provinces and territories in the address form.
3. Taxes calculated by province and shown before payment.
4. Cards, Apple Pay and Google Pay, plus Interac where your processor supports it.
5. Shipping options and delivery times by region.
6. French on every step for Quebec customers.
7. A privacy policy that explains what data you collect and why.

Common mistakes

• Using a US checkout setup with US dollars and US tax rules.
• Shipping e-Transfer orders before confirming the money arrived.
• Applying one tax rate to every province.
• Ignoring French for customers in Quebec.

Frequently asked questions

Can one store sell to both the US and Canada?

Yes, with separate currencies, tax rules and shipping settings for each country. Our guide to US sales tax for online stores covers the US side.

Should my Canadian store have an Arabic version?

If many of your customers are Arab-Canadian families, an Arabic version can make them feel at home and trust you faster.

Is Interac e-Transfer safe for a business to accept?

The transfer itself is secure, but the risk is in the process: shipping before the money arrives, or trusting a screenshot. Confirm every transfer in your bank account and match it to the order number. Transfer limits are set by each bank.

Do I need a Canadian company to sell to Canadian customers?

Not always. Foreign sellers can sell to Canada, but tax registration, payment processing and shipping are easier with a Canadian presence. The right setup depends on your situation, so ask an accountant before you launch.
