How to Accept Payments Online in Canada: Complete Guide for Businesses (2026)
Online shopping in Canada has firmly settled into daily life, with Canadians spending well over $80 billion CAD annually on e-commerce. Whether you're launching a new online store, adding digital sales to a brick-and-mortar shop, or scaling an existing e-commerce operation, understanding how to accept payments online—securely, affordably, and in compliance with Canadian regulations—is essential.
This guide walks through everything Canadian business owners need to know about accepting online payments in 2026, from the technical basics to pricing, security, and platform integration.
The Basics: How Online Payments Work
When a customer pays on your website, a lot happens behind the scenes in just a couple of seconds:
- Customer enters payment info at checkout (card, Interac Online, or a digital wallet like Apple Pay/Google Pay)
- Payment gateway encrypts the data and sends it to your processor
- Processor routes the transaction through the card networks to the issuing bank
- Authorization is returned (approved or declined)
- Funds settle into your Canadian business bank account, typically within 1-2 business days
This entire process now happens in 1-2 seconds on most modern gateways, and increasingly includes real-time fraud screening built into the transaction flow.
What You Need to Accept Online Payments
1. Merchant Account
A merchant account is what allows your business to accept credit and debit card payments online. In Canada, you can get one through:
- A bank - Often slower approval, less competitive pricing, and less flexible support for online-specific needs
- An independent processor like PaymentsPlus - Competitive interchange-plus pricing, faster onboarding, and support tailored to Canadian e-commerce
- An aggregator like Square, Stripe, or Shopify Payments - Fast and easy to set up, but fees add up quickly once you're processing meaningful volume
2. Payment Gateway
The gateway is the software layer connecting your website to the payment processor. Popular options in 2026 include:
- Authorize.net - Still an industry standard, compatible with most Canadian shopping carts
- NMI - Flexible and developer-friendly, popular with processors building custom checkout flows
- Stripe Gateway - Strong developer tools and documentation, widely used for custom builds
- PaymentsPlus Gateway - Included with our merchant accounts, with built-in support for Interac Online and digital wallets
3. Shopping Cart or Checkout
How your customers actually complete a purchase:
- E-commerce platforms - Shopify, WooCommerce, BigCommerce remain the most common choices for Canadian merchants
- Invoicing and payment links - Send secure payment links via email or SMS, ideal for service-based businesses
- Custom integration - API-based checkout for businesses with custom-built websites or apps
- Buy Now, Pay Later (BNPL) - Klarna, Afterpay, and PayBright by Affirm continue to be popular add-ons for Canadian retailers looking to boost conversion
Pricing for Online Payments in 2026
Online transactions (card-not-present) cost more to process than in-person payments because of the higher fraud risk. Typical Canadian rates today look like this:
| Processor Type | Typical Rate |
|---|---|
| Aggregator (Stripe, Square) | 2.9% + $0.30 CAD |
| Bank | 2.4-3.4% + $0.25 CAD |
| PaymentsPlus (interchange-plus) | Interchange + 0.30% + $0.10 CAD |
For a $100 CAD transaction:
- Stripe: approximately $3.20
- PaymentsPlus: approximately $2.05-2.15
That's roughly $1.00-$1.15 saved per transaction—which adds up quickly once you're processing hundreds or thousands of orders a month. For a business doing $50,000 CAD/month in online sales, that difference can mean $500+ in savings every month.
E-commerce Platform Integration
Shopify
Shopify remains the most popular platform among Canadian small businesses. Shopify Payments (powered by Stripe) is the default option, but you can use a third-party processor instead. With PaymentsPlus:
- Integrate through our app or via Authorize.net
- Get lower effective rates than Shopify Payments at higher volumes
- Keep every Shopify feature, including Shop Pay, local delivery, and POS integration
Note: Shopify still applies a transaction fee (typically 0.5%-2%) when you use an external gateway instead of Shopify Payments, so run the numbers based on your monthly volume before switching.
WooCommerce (WordPress)
WooCommerce continues to work well with most gateways and remains a strong choice for Canadian businesses that want more control over their site. Integration is straightforward:
- Install the WooCommerce plugin and your gateway extension
- Add your gateway credentials
- Test thoroughly in sandbox mode
- Go live and monitor your first transactions closely
Custom Websites and Apps
For custom builds, most Canadian developers now use one of these approaches:
- Hosted payment pages - Customer is redirected to a secure, gateway-hosted payment form
- API integration - Payment form embedded directly on your site
- JavaScript tokenization / hosted fields - The most secure and most common modern approach, keeping raw card data off your servers entirely
Security Requirements for Canadian Merchants
PCI Compliance
Any business accepting card payments must maintain PCI DSS compliance (now on version 4.0.1, with full enforcement in effect). In practice, this means:
- Using secure, encrypted connections (HTTPS/TLS) across your entire checkout flow
- Never storing raw card data yourself—let your gateway or processor handle it
- Completing an annual PCI Self-Assessment Questionnaire (SAQ)
Most Canadian merchants using a hosted gateway or tokenized checkout qualify for the simplified SAQ-A, and your processor should help you complete it at no extra charge.
3D Secure 2 (3DS2)
3D Secure has evolved significantly. The current standard, 3DS2, is far less disruptive to the customer experience than older versions:
- Risk data is checked in the background during checkout
- Only higher-risk transactions trigger a step-up verification (biometric approval, one-time code, or bank app confirmation)
- Low-risk purchases can pass through with no extra friction at all
Benefits for Canadian merchants:
- Reduced fraud exposure
- Liability shift for certain chargebacks (the issuing bank absorbs the risk instead of you)
- Increasingly expected for higher-value transactions and recurring billing
Address Verification Service (AVS) and Interac Online
AVS checks the billing address against the card issuer's records and remains a simple, effective way to reduce fraud. Canadian merchants should also consider offering Interac Online or Interac Debit for e-commerce, which lets customers pay directly from their bank account—a payment method many Canadians still prefer for larger online purchases.
Reducing Online Fraud in 2026
E-commerce fraud continues to evolve, with more sophisticated bot attacks and card-testing schemes targeting Canadian retailers. Protect your business with these layered defenses:
- Use AVS and CVV verification - Require billing address match and card security code on every transaction
- Enable 3D Secure 2 - Especially for high-ticket items and first-time customers
- Set velocity limits - Flag multiple purchase attempts from the same card or IP address in a short window
- Review flagged orders manually - Don't rely solely on automation for unusual or high-value orders
- Use AI-powered fraud scoring - Services like Kount, Signifyd, or your gateway's built-in fraud tools now use machine learning to catch patterns human reviewers would miss
- Monitor chargeback ratios - Card networks tightened chargeback threshold programs in recent years; staying under 0.9% helps you avoid extra fees and account reviews

Frequently Asked Questions
What is the cheapest way to accept online payments in Canada?
Interchange-plus pricing through an independent Canadian processor is typically the cheapest option once your business processes more than a few thousand dollars a month. Flat-rate aggregators like Stripe or Square are easier to set up but cost more per transaction as volume grows. Comparing your actual monthly statement against an interchange-plus quote is the best way to see real savings.
Do I need a Canadian business number to accept online payments?
Yes, most Canadian merchant account providers and payment gateways will require your business number (BN) from the CRA, along with basic incorporation or registration documents, to open a merchant account and verify your business for CAD settlement.
Can I accept Interac e-Transfer or Interac Online for e-commerce?
Yes. Interac Online lets customers pay directly from their bank account during checkout, and many Canadian gateways now support it alongside card payments. Interac e-Transfer can also be used for invoicing or manual payment requests, though it's less common for automated e-commerce checkout flows.
How long does it take to set up online payments for a Canadian business?
With an independent processor like PaymentsPlus, most Canadian merchants can be approved and integrated within 1-3 business days. Bank merchant accounts often take longer, sometimes 1-2 weeks, due to more extensive underwriting requirements.
