Square vs Moneris Fees in 2026: True Cost for Canadian Restaurants

Square and Moneris advertise an identical headline rate of 2.65% plus CA$0.10 for in-person credit card processing. Their handling of Interac debit tells a different story. Moneris charges a flat CA$0.12 per tap or insert under its Flat Rate pricing. Square applies its full 2.65% plus CA$0.10 fee to both credit and debit payments. This lack of a debit discount creates a massive cost gap for Canadian restaurants.

Canadian diners frequently pay for meals using debit cards. Square's percentage-based debit pricing severely impacts restaurant profitability. Paying a percentage fee plus ten cents on a basic debit transaction inflates Interac debit costs compared to paying a fixed twelve-cent fee. Square's blended rate structure penalizes high-volume debit venues over time.

Moneris Flat Rate pricing delivers lower fees for debit and online processing than Square Standard. Both processors match on in-person credit at 2.65% plus CA$0.10. Moneris charges 2.85% plus $0.30 for card-not-present sales, beating Square's 2.9% plus CA$0.30 online rate. The sharpest divide occurs on in-person Interac debit. Moneris charges CA$0.12 per transaction. Square charges 2.65% plus CA$0.10.

Moneris Flat Rate pricing includes fraud prevention tools at no additional cost and removes separate interchange or network assessment fees. The model supports American Express, Mastercard, Visa, UnionPay, Discover, and JCB. Moneris provides next-day deposits through established partnerships with BMO and RBC. Online card-not-present Interac debit payments on Moneris Flat Rate carry a $1.00 fee.

Square's percentage-based debit structure pushes its all-in effective processing rate to 2.85% for in-person dining sales. We calculated a scenario for a restaurant processing CA$10,000 per month in card volume with a CA$50 average sale across 200 monthly transactions (split 60% credit and 40% debit). Square Standard card-present processing costs CA$285 per month, or CA$3,420 per year. Processing that same volume online costs CA$350 per month, totaling CA$4,200 per year at a 3.5% effective rate. This creates a CA$780 annual spread.

Uniform percentage pricing hits high-volume Canadian merchants hard. A restaurant processing CA$25,000 per month with a CA$50 average sale across 500 transactions (60% credit, 40% debit) pays CA$712.50 per month for Square Standard card-present processing. That equals $8,550 per year at a 2.85% effective rate. Online processing at this volume costs CA$875 per month, reaching CA$10,500 per year at a 3.5% effective rate. Because Square prices debit and credit identically, merchants lose the cost advantage of flat per-transaction debit processing. Achieving parity between advertised and actual rates means scrutinizing these debit penalties.

Established restaurants can slash processing expenses by dropping flat-rate pricing for Moneris's Simplified Pricing model. This Interchange Plus structure passes wholesale credit card network interchange rates directly through to the merchant along with a fixed markup. This prevents merchants from paying inflated flat fees on lower-cost cards.

Our tracked network rate cards show the Visa CA Consumer Electronic Small Merchant interchange rate is just 0.77%. Restaurants remaining on a 2.65% flat rate subsidize their processor by paying over three times the baseline interchange cost on eligible transactions. Premium cards carry higher rates, with the Visa CA Infinite Privilege CNP Small Merchant interchange rate hitting 2.3%. However, restaurants with strong sales volume still save money under Moneris's Simplified Pricing because wholesale rates adjust based on card types rather than a rigid flat fee.

Moneris imposes mandatory minimums and incidental service charges that complicate its fee structure. Specific Moneris account fees include a $25.00 chargeback fee, $5.00 for Moneris Go software, a $5.00 minimum merchant discount fee, and a $2.00 paper statement fee. Moneris charges $80.00 for authorization chargeback handling. Minor administrative fees include $0.08 for dial communications and $2.50 for aged close batches.

Square maintains a straightforward fee model without published monthly subscription fees on its base tier. Canadian merchants using Square Point of Sale, Plus, or Premium face no published fees. The base Square Online free plan in Canada similarly costs nothing monthly. Square avoids incidental statement and software charges. Canadian restaurants must weigh these operational savings against Square's steep underlying processing costs on debit transactions.
