If you're a Canadian business owner trying to decide how to accept credit and debit cards, you've likely narrowed your search down to two familiar names: Moneris and Square. Both are household names in Canadian payment processing, but they serve very different types of businesses in very different ways. Choosing the wrong one can mean overpaying in fees, dealing with clunky hardware, or outgrowing your system within a year.
Moneris, co-owned by RBC and BMO, is Canada's largest and most established payment processor, with deep roots in traditional retail, restaurants, and enterprise-level businesses. Square, by contrast, built its reputation on simplicity and transparency, appealing to startups, mobile vendors, and small shops that want to get up and running quickly without a lot of paperwork.
So which one actually fits your business? In this guide, we'll compare Moneris vs Square across pricing, hardware, features, customer support, and contract terms - all through the lens of what matters most to Canadian small and medium businesses. By the end, you'll have a clear picture of which processor deserves your business, or whether a third option might serve you even better.
Moneris vs Square: The Quick Overview
Before diving into the details, here's the high-level distinction that shapes everything else in this comparison.
Moneris is a Canadian-built, bank-backed processor with decades of experience serving everything from corner stores to national retail chains. It offers a wide range of hardware, custom pricing plans, and dedicated account support, but it has traditionally required contracts and can involve more setup complexity.
Square is a U.S.-founded fintech company that expanded into Canada with a simplified, flat-rate pricing model and plug-and-play hardware. It's popular with new businesses, mobile sellers, and anyone who values speed and transparency over customization.
Neither processor is universally "better" - the right choice depends on your transaction volume, business type, and how much hands-on support you need. Compare processors side by side to see how these two (and others) stack up against your specific needs.
Pricing Comparison: What Will You Actually Pay?
Pricing is usually the deciding factor for Canadian business owners, so let's break down how each processor charges.
Moneris Pricing
Moneris typically offers:
- Interchange-plus or tiered pricing, often negotiated based on your monthly processing volume
- Monthly fees that vary by plan, sometimes bundled with terminal rental
- Custom quotes rather than one-size-fits-all rates, meaning higher-volume merchants can often negotiate better rates
- Equipment costs that can be purchased, leased, or rented depending on the agreement
The upside is that established or growing businesses processing significant monthly volume can often secure lower effective rates than Square's flat pricing. The downside is that pricing isn't transparent upfront - you need to request a quote to know what you'll actually pay.
Square Pricing
Square uses a simple, flat-rate model:
- A fixed percentage per transaction (typically higher than negotiated interchange-plus rates for established businesses)
- No monthly fees on its basic plans
- No long-term contracts
- Pricing is the same whether you process $500 or $50,000 a month
This simplicity is great for new businesses that want predictability, but it can become expensive as your sales volume grows, since there's no opportunity to negotiate a lower rate.
The bottom line: if you're processing higher monthly volumes, Moneris' negotiated rates will likely save you money over time. If you're a new or low-volume business that values predictable costs, Square's flat rate may be easier to manage.

Hardware and POS Systems
Moneris Hardware
Moneris offers a broad range of terminals and POS systems, including standalone card terminals, countertop systems, and integrated POS solutions designed for restaurants, retail, and healthcare environments. Many of these integrate with existing business software and third-party POS platforms, making Moneris a strong fit for businesses that already have systems in place.
Square Hardware
Square is known for its sleek, affordable hardware - the Square Reader, Square Terminal, and Square Register are all designed to be set up in minutes with minimal technical know-how. This makes Square especially appealing to mobile vendors, pop-up shops, and service providers who need to accept payments on the go.
If you're also evaluating dedicated POS hardware providers, it's worth taking a look at our Clover comparison and Lightspeed comparison pages, since many Canadian businesses end up choosing a POS system first and a processor second.

Contracts, Fees, and Flexibility
One of the biggest differences in the Moneris vs Square debate comes down to contract terms.
Moneris has historically required merchant agreements, which may include terms around equipment leasing, early termination fees, and minimum processing commitments. This isn't necessarily a bad thing - it often comes with dedicated account management and more customized service - but it's a bigger commitment than many small business owners expect.
Square, true to its startup roots, operates on a no-contract, cancel-anytime basis. There are no early termination fees, and you can stop using the service whenever you like. This flexibility is attractive, but it's worth noting that the trade-off is typically higher per-transaction costs over time.

Customer Support and Canadian Compliance
Support quality can make or break your experience, especially when a terminal goes down during your busiest hour.
Moneris offers 24/7 Canadian-based phone support and has a large network of technicians and account representatives across the country. Because it's backed by major Canadian banks, it also has deep familiarity with Canadian regulatory requirements, PCI compliance standards, and CAD settlement timelines.
Square offers support primarily through chat and email, with phone support available but sometimes harder to reach quickly. Square does support CAD transactions and settles in Canadian dollars, but as a company with U.S. origins, some Canadian merchants report that niche compliance questions take longer to resolve.
For businesses in major Canadian markets, local considerations matter too. If you're operating in Toronto payment processing, Vancouver payment processing, Calgary payment processing, Montreal payment processing, or Ottawa payment processing markets, you'll want a processor with strong regional support - something worth asking about directly.
Other Processors Worth Considering
While this article focuses on Moneris vs Square, they aren't the only two options for Canadian businesses. Depending on your situation, it may also be worth comparing:
- Stripe for developer-friendly online payments - see our Stripe comparison
- TD for bank-bundled processing if you already have a business banking relationship - see our TD comparison
- Desjardins if you operate primarily in Quebec - see our Desjardins comparison
- Chase Paymentech for larger, enterprise-level processing needs - see our Chase comparison
Every business is different, and the "best" processor is the one that matches your specific volume, industry, and growth plans.
Making the Right Choice for Your Business
So, Moneris vs Square - which one actually fits your Canadian business? Here's a simple way to think about it:
- Choose Moneris if you process significant monthly volume, need integrated POS hardware, operate in a regulated industry like healthcare, or want dedicated Canadian support with negotiated rates.
- Choose Square if you're a new or low-volume business, need mobile payment flexibility, want to avoid contracts, and prioritize simplicity over the lowest possible rate.
- Consider a specialized processor if your industry has unique needs that neither Moneris nor Square addresses well out of the box.
