The verdict in three sentences
For a Toronto e-commerce brand selling 500,000 to 5M CAD a year, Stripe or Shopify Payments as the main gateway, plus PayPal, give the best balance of fees, conversion and integration in 2026. When US customers exceed 25 % of orders, cross-border and currency conversion fees become the biggest cost line, so pricing and settling in USD matters more than the headline rate. Above roughly 3M CAD, an interchange plus provider such as Helcim, Moneris or Adyen is worth putting in competition.
The 2026 gateway ranking
The ranking uses stable criteria: total cost on your volumes, conversion impact, cross-border handling, payout speed and reversibility (can you take stored cards with you). Fees are rough figures from 2026 public rate cards for standard Canadian cards, to verify on each provider's site before signing.
| Rank | Gateway | Domestic card fees (2026 estimate) | Payout | Strengths | Best fit |
|---|---|---|---|---|---|
| 1 | Stripe | Around 2.9 % + 0.30 CAD, plus surcharges for international cards and currency conversion | 2 to 7 business days | Developer tools, fraud screening, multi-currency settlement | Brands with custom or headless stores |
| 2 | Shopify Payments | Tied to your Shopify plan, lower on higher plans | 2 to 3 business days | No extra gateway fee on Shopify, native wallets | Brands on Shopify |
| 3 | PayPal (as a second method) | Higher, around 2.9 % plus a fixed fee, more for cross-border | Instant to PayPal balance | Trust, especially with US shoppers | Everyone, as a complement |
| 4 | Helcim | Interchange plus model, published margins | 1 to 2 business days | Transparent pricing, falls with volume | Brands above 1M CAD |
| 5 | Moneris | Negotiated, often bundled with in-store terminals | 1 to 2 business days | Canadian bank backing, omnichannel with stores | Retailers with physical locations |
| 6 | Buy now pay later (Affirm, Klarna, PayPal Pay in 4) | Roughly 3 to 6 %, 2026 estimate | 1 to 7 days, provider carries credit risk | Higher basket size | Baskets above 150 CAD |
Interac is how many Canadians pay at the till, but online debit support varies by gateway and changes over time, so ask each provider exactly which Interac flows they support for e-commerce. Kolonell can integrate the chosen gateway as part of a build or a maintenance plan at 38, 76 or 115 EUR a month.
Cross-border: where the real cost hides
| Scenario for US orders | Typical extra cost (2026 estimate) | Better approach |
|---|---|---|
| Price in CAD, US card pays in CAD | International card surcharge around 0.8 to 1 %, plus shopper's bank FX fee | Show USD prices to US visitors |
| Price in USD, settle into CAD account | Gateway currency conversion around 1.5 to 2 % | Hold a USD balance or USD bank account |
| Price and settle in USD | Mostly international card surcharge only | Best for 25 %+ US share |
| Duties and taxes collected at checkout (DDP) | Customs broker fees 2 to 5 % of order value | Fewer refused parcels, better US conversion |
| Returns from the US | 15 to 30 CAD per return shipped back | Local US returns address via 3PL |
Sales tax adds another layer: Ontario HST at 13 % on domestic orders, GST or HST by province for the rest of Canada, and US state sales tax obligations once you pass economic nexus thresholds in a state.
Mini case study
Illustrative example: Emma, CEO of an outdoor apparel brand in Toronto's Liberty Village, sells 2,500,000 CAD online with 40 % of revenue from US customers. Pricing in CAD and converting everything, she pays around 2.9 % + 0.30 CAD on 21,000 orders (about 78,800 CAD), plus roughly 1 % international surcharge and 2 % conversion on 1,000,000 CAD of US sales (30,000 CAD): 108,800 CAD a year. By pricing US orders in USD and holding a USD balance, she removes most of the conversion fee, saving about 20,000 CAD. Adding Pay in 4 on baskets above 150 CAD lifts their conversion by roughly 10 %.

Which gateway should a Toronto e-commerce brand choose?
Stripe if your store is custom or headless, Shopify Payments if you are on Shopify, with PayPal as a second method. Above roughly 3M CAD, put an interchange plus provider in competition.
How much do cross-border fees cost?
Converting US payments into CAD typically adds 1.5 to 2 % on top of an international card surcharge of around 1 %. On 1M CAD of US sales, that can mean 25,000 to 30,000 CAD a year.
Can customers pay with Interac online?
Support depends on the gateway and evolves, so confirm the exact flow before signing. Many brands rely on cards, wallets and PayPal online and keep Interac for in-store terminals.
Is buy now pay later worth it?
Usually above 150 CAD baskets, where conversion gains of 8 to 15 % outweigh fees of roughly 3 to 6 %. Below 75 CAD, the fees often eat the gain.
How long does switching gateways take?
Two to 10 days of integration depending on the platform, plus 1 to 2 weeks of testing. Migrating stored cards for subscriptions between providers takes 3 to 6 weeks.
