Moneris Canada Interchange Rates in 2026: Flat Rate vs Simplified Interchange Plus

Moneris offers Canadian merchants two primary pricing structures: a published Flat Rate plan charging 2.65% plus CA$0.10 per in-person credit transaction, and a Simplified Pricing Interchange Plus model that adds a 0.4% markup to wholesale card network rates. We break down these models to expose the immediate cost differences for storefront and online businesses.

Under the Flat Rate structure, card-not-present transactions carry a rate of 2.85% plus CA$0.30, while in-person Interac debit transactions are priced at a flat CA$0.12 per transaction (or CA$1 for online debit). Simplified Pricing passes through wholesale interchange costs alongside network assessments, but Moneris adds a uniform 0.4% transaction fee markup. All Moneris processing plans apply an additional 0.8% fee for foreign card payments. Our Moneris interchange-plus rate breakdown exposes exactly how these processor markups bloat your actual costs.

Moneris's Flat Rate plan yields an effective rate of 1.81% for standard card-present retail volume compared to 1.94% on Simplified Pricing Interchange Plus, making Flat Rate the cheaper option across all monthly sales volumes. In our benchmark scenario evaluating a merchant processing $10,000 per month with a $50 average sale across 200 transactions (60% credit / 40% debit), Flat Rate card-present processing costs CA$180.60 per month ($2,167.20 per year). Simplified Pricing card-present processing costs CA$194 per month ($2,328 per year), assuming an average tracked credit interchange of 1.54% plus the 0.4% markup. To see how these figures stack up against competitors, review what Canadian retailers actually pay.

When volume scales to $25,000 per month across 500 transactions under the same 60% credit / 40% debit mix, Flat Rate card-present processing totals CA$451.50 per month ($5,418 per year). Simplified Pricing card-present costs CA$485 per month ($5,820 per year). Online merchants on Flat Rate processing $25,000 per month pay CA$717.50 monthly ($8,610 annually). This results in an annual spread of CA$3,192 between the cheapest card-present option and the most expensive online option.

Because Simplified Pricing charges a 1.94% marginal all-in rate compared to 1.81% on card-present Flat Rate and carries no offsetting volume tier discount, Flat Rate remains cheaper at every processing volume for this transaction mix. The mathematical advantage of Flat Rate persists as volume rises because the interchange-plus structure fails to provide a reduced price tier for debit volume.

Interac debit transactions in Canada cost a fixed per-transaction fee rather than a percentage of sale value. Debit pricing acts as the decisive factor in Canadian merchant processing costs. On the card-present Flat Rate plan, merchants pay a direct rate of CA$0.12 per Interac transaction. Under Simplified Pricing, Moneris eliminates this advantage by pricing Interac debit identically to credit cards, charging its percentage markup across all volume. We observe similar dynamics when we compare TD Merchant Solutions interchange plus rates vs Moneris.

At the wholesale infrastructure layer, card brand networks routinely update base costs for debit routing. Effective November 1, 2026, Interac is increasing the Switch fee and Mobile Service fee from $0.015803 to $0.016315 CAD per transaction. Because Flat Rate contracts absorb wholesale card brand rate shifts into a fixed cost structure, merchants on Flat Rate avoid direct exposure to network switch adjustments.

Network fee revisions taking effect in late 2026 directly impact Canadian interchange-plus merchants through adjustments to Visa interchange rates and new Mastercard system charges. Effective October 24, 2026, Visa is reducing its Consumer Electronic Small Merchant interchange rate from 0.77% to 0.70%. Visa is simultaneously increasing its Business Credit Standard interchange rate from 2.00% to 2.15% on the same date. Visa Infinite Privilege card-not-present Small Merchant rates track at 2.3%.

Mastercard is rolling out structural system access fees that apply directly to Canadian processing statements. On October 19, 2026, Mastercard introduces the Acquirer Network Access and Brand Usage (NABU) fee, set at $0.022035 USD for domestic transactions and $0.033335 USD for foreign transactions. Mastercard also establishes a Force Post Transaction fee of $0.1017 USD effective July 20, 2026, and increases its Merchant Advice Code fee to $0.5650 USD effective April 1, 2026.

Additional digital payment assessments take effect throughout 2026 across both card networks. Visa introduced a Card Present Token fee of 0.0113% for domestic digital wallet contactless transactions and a Digital Commerce Services Fee of 0.01695% for card-not-present payments on June 1, 2026. Mastercard updated its digital enablement fee on May 25, 2026, to 0.0226% for transactions between $100.01 USD and $9,999,999.99 USD. It also launched a temporary Underpenetrated Verticals program running from July 1, 2026, through June 30, 2027.

Moneris imposes rigid operational commitments on merchants. These include a three-year initial agreement, mandatory terminal rentals, and strict fee schedules for account adjustments. Small-business terms mandate a three-year initial contract with automatic six-month renewal cycles. To prevent automatic renewal, merchants must provide written cancellation notice at least 45 days prior to the renewal date. Early termination carries a $300 deactivation fee per location.

Hardware costs add ongoing fixed expenses to Moneris processing accounts. Hardware rentals, such as the Moneris Go terminal, cost $34.95 per month. Merchants pay return shipping fees upon agreement termination, and rental charges continue until Moneris physically receives the hardware. Following private equity firm Francisco Partners' acquisition of Moneris for approximately C$2.0 billion on August 10, 2026, standard fee schedules continue to enforce these equipment rental policies alongside hardware integrations like the Verifone Victa Portable terminal.

Incidental processing fees increase overall merchant overhead, making it difficult to achieve true parity between advertised rates and final monthly costs. Moneris charges a $25 chargeback fee, an $80 authorization chargeback handling fee, a $5 minimum merchant discount rate floor, and a $2 paper statement fee. Moneris enforces a strict 7-calendar-day window for merchants to respond to chargeback information requests, forfeiting reversal efforts if the deadline is missed.
