Most card-reader comparisons quote US prices and pretend borders don't exist. Canadian merchants need CAD hardware prices, Canadian rates, and an honest answer about Zettle's availability here. This guide gathers all three — with dates — and segments the readers by the monthly volume where each one makes sense.
The three readers at a glance
| Square Reader | Helcim Card Reader | Zettle (PayPal) | |
|---|---|---|---|
| Hardware (CAD) | CA$69 | CA$129 | No CAD pricing found |
| Monthly fee | $0 | $0 | $0 |
| In-person rate | 2.5% (CA credit) | Interchange + 0.40% + 8¢ | 2.29% + 9¢ (USD) |
| Rate model | Flat | Interchange-plus, volume-tiered | Flat |
Hardware prices in CAD, dated
Checked 2026-10-11: Square Reader CA$69, Helcim Credit Card Reader CA$129, BBPOS WisePad 3 CA$79, Shopify Tap & Chip CA$69. Mobile readers typically run CAD $41–$190 — the budget end of card acceptance. One practical note: cheaper readers usually lack a built-in number pad, which means handing your phone to the customer for PIN or tip entry. The Helcim reader's larger touchscreen avoids that awkwardness; decide whether it matters for your counter before you buy on price.
The rate structures: flat vs interchange-plus
Square and Zettle charge flat rates: Square Canada 2.5% on in-person credit (+1.5% for non-Canadian cards), debit at 0.75% + 7¢, no monthly fee. Helcim charges interchange-plus with volume tiers: at $0–$50K a month it's interchange + 0.40% + 8¢ in person; the markup steps down to +0.35% + 7¢ at $50–100K, +0.25% + 7¢ at $100–500K, and +0.15% + 6¢ above $1M. Helcim's chargeback fee is $15 and refundable if you win the dispute.
Worked comparison: at $40,000/month in-person on standard domestic credit (assume ~1.6% average interchange): Helcim costs roughly 2.0% + 8¢ per transaction vs Square's flat 2.5% — about $200/month less on the percentage alone. At $5,000/month, the gap is ~$25/month, and Square's zero-learning-curve setup usually wins on total effort. The crossover sits somewhere in the low tens of thousands per month — which is exactly where you should run your own numbers.
Zettle in Canada: the availability question
Zettle by PayPal looks great on paper: a $29 reader (USD), 2.29% + 9¢ in-person, no monthly fee. But in the Canadian pricing sources checked for this guide, the Zettle reader is listed as unavailable in CAD — no Canadian hardware price, no Canadian rate card. Zettle's published numbers are USD figures for its supported markets. Canadian merchants should confirm current availability and Canadian pricing directly with PayPal before planning around Zettle; until then, treat it as unverified for Canada rather than as a live option.
Who each suits
- Occasional and mobile sellers (markets, pop-ups, tradespeople under ~$10K/month): Square. $0 monthly, CA$69 reader, 2.5% flat — the cheapest way to start and the simplest to run.
- Growing businesses crossing ~$15–25K/month: price Helcim seriously. Interchange-plus beats flat 2.5% once volume is real, and the markup keeps stepping down as you grow.
- Businesses needing an ecosystem (online store, invoices, appointments in one dashboard): Square — the reader is the on-ramp to a full POS, not just a dongle.
- PayPal-centric sellers: Zettle — but only after confirming Canadian availability and CAD pricing; don't build on USD figures.
Note: this is a comparison explainer, not a procedure guide — no steps here, just the published-rate math to check against your monthly volume.
