How to switch payment processors in Canada without downtime

Switching processors feels riskier than it is

Two fears keep Canadian merchants stuck in contracts they've outgrown: losing a day of sales mid-switch, and getting hit with a cancellation penalty. Both have answers. Downtime is solved by running your old and new processor at the same time — which is allowed and even encouraged. Penalties are far more limited than most contracts make them look, because merchants in Canada have specific, written exit rights. We're an independent merchant-services provider in the GTA — here is our honest, step-by-step version of how a clean switch works.

Your rights under Canada's Code of Conduct (the 2024 version)

The Code of Conduct for the Payment Card Industry in Canada does the heavy lifting in any switch. The current version took effect October 30, 2024, and every major card network operating in Canada has agreed to it — Visa, Mastercard, American Express, Interac, Discover and UnionPay — with acquirers on the hook for their downstream processors and sales organizations too. Three rights matter most when you want to leave:

• 30–60 days' warning. Your processor must notify you between 30 and 60 calendar days before the effective date of any fee increase or any new fee passed on to you, and the notice must spell out the old and new amounts and the exact date your exit window closes.
• 70 days to leave without penalty. You can cancel your card-processing agreement — including related service agreements — without any form of penalty, within 70 calendar days after the fee change takes effect.
• Cancel anytime if you weren't told. If you never received the required 30–60 days' notice, you have the right to cancel without penalty at any time.

One correction worth making: plenty of Canadian articles still describe a "90-day rule" that let you cancel within 90 days of receiving notice. That was the 2015 Code, retired on October 30, 2024. The current window is 70 calendar days, and it runs from the date the change takes effect, not the date you were notified.

The Code protects you at renewal too: you can give notice of non-renewal at any point up to 45 calendar days before your renewal date, and a standard fixed-term agreement can't auto-renew for another full term — only for extensions of six months or less. Your processor also can't add a new product or service without your express consent.

Step 1: Read your current contract — and price out the exit

Before talking to anyone, pull out your merchant agreement and find four things:

1. The term and renewal date. Canadian merchant contracts commonly run three to five years; if your term is nearly over, the 45-day non-renewal notice can be the cheapest exit of all.
2. The early-termination clause — and which kind it is. Flat early-termination fees typically sit in the $250–$500 range, but "liquidated damages" clauses are the expensive kind: they charge the processor's estimated lost revenue for the remainder of the term, which can run into the thousands. Some contracts stack both. Industry guides put the overall range, as of July 2026, at roughly $250 to over $5,000.
3. Any separate terminal lease. Equipment leases are often a distinct contract with a third-party leasing company, frequently backed by a personal guarantee — and they can sit outside the Code's protections entirely. Cancelling your processing does not automatically cancel your lease; read it on its own and ask about buy-out terms.
4. Pre-scheduled fee increases. The 70-day penalty-free right does not apply to increases written into your agreement on a set schedule — the end of a promotional rate, for example.

Step 2: Get a real comparison before you commit

The Code works for you here as well: every processing quote in Canada must include a Cost per Transaction Disclosure and a Disclosure of Fees, along with the card-mix and volume assumptions behind them — specifically so merchants can compare offers line by line. If one of the options on your list is a flat-rate provider, Square fees in Canada vs. an independent processor: honest math walks through how that model stacks up against an independent processor. Hold any quote against your current statement's effective rate, not against the teaser rate you were originally sold (Credit card processing fees in Canada: junk fees explained shows how to work it out). If you'd rather not do the arithmetic, we run a free, line-by-line statement audit for exactly this purpose: it puts a dollar figure on the switch before you sign anything.

Step 3: Open the new merchant account before you cancel anything

This is the one rule that makes downtime impossible: the new account goes live while the old one is still running. Opening a merchant account in Canada generally takes 2 to 7 business days for the application, underwriting and verification — longer for complex or higher-risk businesses. Have your business registration, banking details and tax information ready; underwriters may also review the owners' credit history. Order the new terminal at the same time so hardware isn't the bottleneck (our terminal lineup starts at $25/month).

Step 4: Run both processors at the same time

The overlap is the whole no-downtime mechanism, and it's allowed and encouraged. With the new terminal on the counter and the old one still live:

• Run small test transactions on the new system — a credit sale, an Interac debit sale, a refund and a void.
• Confirm the deposits arrive in the right bank account, on the schedule you expect.
• Train your staff on the new terminal during quiet hours.
• Set a firm go-live time — a quiet mid-week morning, never a Saturday rush — and move your traffic only once everything above has checked out.

The overlap has a second benefit: you can compare your first new statement against the old one, in real dollars, before anything is final.

Step 5: Cancel the old account last — and in writing

Only after the new system is live and verified do you cancel, and you do it in writing. Under the Code, your processor must send you the cancellation documents within 5 business days, and cancellation takes effect on the date you request — provided you've met your obligations (returned rental equipment, for instance) and the date is at least 30 calendar days after you submit the documents, or earlier if both sides agree. Before the account fully closes, wait for the final deposits, settle any outstanding refunds and chargebacks, and download every past statement — you'll want them for your books and for any complaint. Time the whole project away from your peak season.

A realistic no-downtime timeline

Underwriting, integrations and your own contract dates move the edges, but notice what never appears in this sequence: a moment when you can't accept a card.

What if my current processor doesn't play fair?

The Code has a complaints process with deadlines. A processor must acknowledge a Code complaint within a maximum of 5 business days, and investigate and address it within a maximum of 20 business days. If that stalls, you can escalate to the acquirer or the card network, and you can file a complaint with the FCAC at any stage — the FCAC monitors compliance with the Code, though it doesn't resolve individual disputes or award compensation. Keep the paper trail: notice dates, statements, and your written cancellation request.

Can I really cancel without penalty?

Yes — within the rules. If a fee was increased or added and you act within 70 calendar days of the change taking effect, the processing agreement and its related service agreements end penalty-free. If you never got the 30–60 days' notice, you can leave at any time. The window doesn't cover increases pre-scheduled in your contract, and a third-party terminal lease may live outside the Code altogether. When no penalty-free route applies, do the math anyway: a flat few-hundred-dollar fee is a known cost you can weigh directly against the monthly savings your statement audit found.

Will I lose sales during the switch?

Not if you keep the order straight. The only way a switch causes downtime is cancelling the old account before the new one is proven — and every step above exists to prevent exactly that. The worst case of a well-run switch is two terminals on the counter for a short while.

If you'd like company for it: Newdays is an independent merchant-services provider in the GTA working with nail salons, hair salons, convenience stores, cafés and restaurants.
