Fraudulent Chargebacks on Shopify in Canada: Fight or Fold? (2026)

The email says a customer in another province claims they never made the purchase. The parcel left your shop three weeks ago. The goods are gone, the money is gone and a C$15 fee has been taken on top. Fraudulent chargebacks on Shopify are the dispute type owners dread most, and the one where a calm look at the evidence decides whether you fight or fold.

Quick answer: A fraudulent chargeback means the cardholder says they did not authorize the payment. Shopify tells you to contact the customer first, then, if the charge was valid, submit the fulfillment date and time, billing information, IP address and country, and shipping and tracking details. Real card fraud and friendly fraud look alike on the surface, so check the order signals before you decide. Fight when the evidence ties the cardholder to the order. Fold when it does not.

This guide is for you if:

• You sell on Shopify Payments from Canada and a customer says they never authorized a purchase.
• You want to tell stolen card fraud from a customer who forgot or regrets an order.
• You want a repeatable way to decide whether to fight and what to send.

Disclosure: ChargeFix publishes this guide and sells an app for Shopify Payments disputes. The Shopify rules come from Shopify's Help Center, and other figures come from named sources, all listed at the end. Where a figure is global or American, the text says so, because no verified Canadian figure exists.

TL;DR

• Shopify's two reasons for fraudulent chargebacks are Fraudulent and Unrecognized. Both call for the same core evidence.
• Contact the customer first. If the order turns out to be genuine, they ask their bank to drop the dispute, and you still submit evidence.
• Shopify cannot request early resolution on Visa disputes coded as Fraudulent.
• Shopify Protect is for US stores only, so a Canadian store carries fraud losses itself.
• Fraud coded disputes are won less often than most types, about 17% on average in one global dataset, so fight selectively.

Do this today

1. Open the dispute in your Shopify admin and note the reason, amount and due date.
2. Pull the order's billing details, IP address and country, shipping address and fulfillment record.
3. Check whether the customer has bought from you before without a dispute.
4. Contact the customer through the email on the order, if that looks safe.
5. Decide to fight or fold using the cost sheet in this guide, and file before the due date.

Fraudulent chargebacks on Shopify in Canada: the process in one table

Step	What you do	Why
1. Read the dispute	Note reason, amount, due date	The window is 7 to 21 days, with no extensions
2. Contact the customer	Email or call, if safe	A genuine buyer may drop it
3. Pull order signals	Billing, IP, country, shipping, history	These decide the case
4. Decide	Fight or fold	Fraud disputes are hard to win
5. Build the response	Facts first, in Shopify's evidence order	A clear case beats a long one
6. File	Before the due date	Shopify sends only saved data otherwise
7. Review	Note the cause for your next audit	Prevention beats representment

What is a fraudulent chargeback on Shopify?

A fraudulent chargeback is a dispute where the cardholder tells their bank the payment was never theirs. Shopify's reasons page describes it this way: the cardholder says they did not authorize the charge, often because the card was stolen. A related reason, Unrecognized, covers a customer who does not recognize the merchant name or location on the statement.

Behind the label on fraudulent chargebacks there are three different situations, and they need different responses.

What really happened	How it presents	What to do
True card fraud	A criminal used a stolen card	Fight only if the evidence ties the real cardholder to the order
Friendly fraud	The cardholder made the purchase and disputes it anyway	Fight, with proof of their involvement
Honest confusion	The customer forgot the purchase or did not recognize the name	Contact them, show the receipt, ask them to withdraw

Shopify's own advice for both Fraudulent and Unrecognized starts the same way: contact the customer first. A household member may have made the purchase, or the customer may simply not recognize your business name on their statement. If they agree the charge was valid, they can ask their bank to drop the chargeback.

What does Shopify tell you to submit for fraudulent chargebacks?

Shopify's reasons page is specific. If you believe the customer is wrong, the page asks for the dispute's core records: when it was fulfilled, how the buyer paid, where the order was placed and how it shipped. If the customer agrees the charge is valid, include their statement as well, and still submit evidence.

That gives you a core list.

Evidence	What it shows	Where to find it
Fulfillment date and time	You delivered what was ordered	Order timeline in Shopify
Billing information	The billing address matched the card	Order details
IP address and country	Where the order was placed	Order details
Shipping address and tracking	Where it went and that it arrived	Fulfillment and carrier records
Customer statement	They confirm the purchase	Email, saved as PDF
Past undisputed orders	A history of genuine purchases	Customer record

Shopify automatically includes some order data in your response, such as shipping and tracking information, and your billing information is part of the order record. That is the bare minimum, and it does not tell the story. A response that explains why this order points to the real cardholder beats one that sends raw fields.

Files must be PDF, JPEG or PNG, up to 2 MB each and 4 MB combined, with one file per evidence type and no links, audio or video. Use high contrast images that print clearly in black and white, because some banks receive evidence by fax.

Can Shopify resolve a fraud dispute early?

Not always. Shopify's page on resolving disputes notes that it cannot request early resolution for American Express disputes or for Visa disputes coded as Fraudulent. In those cases the dispute runs its course, so your evidence matters from the start.

Remember the timing. Shopify's response window runs from 7 to 21 days with no extensions. After you submit, the card company decides up to 75 days later, and that decision is final. You cannot add evidence once you have responded. A won chargeback can also be disputed again.

Rule	What it means for a fraud dispute
7 to 21 day window, no extensions	Gather evidence on day one
One submission	Make the first response complete
Up to 75 days for a decision	Plan cash flow around it
Decision is final	Choose your fights carefully
Won disputes can be re-disputed	Keep your file after a win

How do you tell real fraud from friendly fraud in fraudulent chargebacks?

This is the question that decides your approach. The signals sit in the order data, and most are easy to check.

Signal	Points toward real fraud	Points toward friendly fraud
Billing and shipping address	Different, with no relationship	The same, or a known household
IP country vs billing country	Far apart	Close or the same
Customer history	New customer, big first order	Repeat customer with past undisputed orders
Email and name	Odd, random or mismatched	Matches the cardholder
Order pattern	Several cards, rushed, high value goods	Ordinary basket
Delivery	Sent to a freight forwarder or unusual address	Delivered to a normal home address
Contact after delivery	Silence	The customer replied, thanked you or used the product

None of these signals is proof on its own. Read them together when you review fraudulent chargebacks. A repeat customer with undisputed past orders, delivered to their usual address, who emailed to ask about sizing, is almost certainly friendly fraud or honest confusion. A new customer with a billing address in Ontario, an IP address in another country and goods sent to a forwarder looks like stolen card fraud.

Friendly fraud is common among fraudulent chargebacks. Visa puts it at about 20% of fraudulent disputes, up to 30% for high volume online merchants, according to chargeback.io, and Juniper Research puts it at 22% of chargebacks in 2026. Those are global figures, not Canadian ones. We have no verified Canadian share from a named source.

What does Visa's compelling evidence rule mean for your records?

Visa's Compelling Evidence 3.0 is a network rule that helps merchants defend one kind of fraud dispute: Visa reason code 10.4, other fraud in a card absent environment. Its logic is a good model for what to keep, even though Shopify handles the submission form for you.

According to Stripe's documentation on the rule, it asks for at least two earlier transactions on the same payment method that were paid and not disputed, and that fall 120 to 364 days before the disputed one. Matching customer data, such as the IP address or device ID, ties those earlier orders to the disputed one. It does not guarantee a win.

You do not file under a code on Shopify. But the pattern is useful. Compelling evidence of this kind, which shows the same person using the same device or IP address and delivery address, has bought from you before without a dispute is the strongest kind of fraud defence. So keep order history and do not clear it.

Compelling evidence idea	What to save in your store
Earlier undisputed orders	Customer order history, dates, amounts
Matching IP address	IP address and country on each order
Matching delivery address	Shipping address history
Device matches	Whatever device data your store records
Cardholder confirms receipt	Any email where they say the goods arrived

Note the limit. A first time customer has no history, so this evidence cannot help, and a first time order is exactly where fraudulent chargebacks from stolen cards show up.

Should you fight or fold fraudulent chargebacks?

Fraudulent chargebacks are the hardest type to win. Datos Insights puts the merchant win rate on fraud coded disputes at 17%, according to chargeback.io. That figure is a global dataset, but it tells you to be selective.

Use a simple cost sheet on every fraud chargeback. Fighting costs time. Folding costs the amount, the fee and the goods. If you win, the amount and fee return, and the goods question disappears because the sale stands.

Fight or fold: cost sheet (fill in)

Disputed amount                     = A
Chargeback fee (C$15 or US$15)      = F  (returned only on a win)
Goods and shipping already spent    = G
Your time to build the response     = T  (hours x your hourly value)

If you fold:  loss = A + F + G
If you fight and win:  loss = T  (amount and fee come back)
If you fight and lose: loss = A + F + G + T

Fighting is worth it when:
  (chance of winning) x (A + F + G)  is larger than  T

Example only: A = C$180, F = C$15, G = C$70, T = C$25
  (A + F + G) = C$265
  A 20% chance of winning is worth 0.20 x 265 = C$53, more than C$25
  A 5% chance is worth C$13, less than C$25

The number that matters in fraudulent chargebacks is your honest chance of winning, which you can estimate from the triage sheet. A repeat customer with matching signals might deserve 50%. A new customer with a mismatch might deserve 5%. For high value orders the sum nearly always favours fighting. For low value orders with weak signals it may favour folding, but accepting still costs you, and still counts toward your dispute rate.

Situation	Usual call
Repeat customer, matching signals, delivered	Fight
Customer admitted the order or replied after delivery	Fight, and attach the reply
New customer, mismatched signals, forwarder address	Often fold
Large value, any reasonable evidence	Fight
Small value, no signals either way	Cost sheet decides

How do you build the response?

Lead with the facts that tie the cardholder to the order, in Shopify's order of preference: direct proof first, then customer acknowledgment, then your policies, then supporting context.

Response to a fraudulent chargeback (adapt to your case)

Order #[number], placed [date and time] for C$[amount].

Summary
The cardholder disputes this order as unauthorized. The records below show
the order was placed from the cardholder's usual details and delivered.

1. Billing and order details
   Billing address [address] matches the card on file. The order was placed
   from IP address [ip] in [country].

2. Customer history
   This customer placed [number] earlier orders between [dates], none disputed.
   The delivery address matches earlier orders.

3. Fulfillment and delivery
   Fulfilled on [date and time]. Carrier [name], tracking [number], delivered
   on [date] to [address]. [Signature obtained: yes / no.]

4. Customer communication
   [Date]: the customer wrote [summary]. The email is attached as a PDF.

Attached files: [list, one per evidence type]

Keep a fraudulent chargeback response short, factual and in order. Do not accuse the customer of fraud, and do not guess. State what the records show and let the reviewer decide.

Why do fraudulent chargebacks on Shopify happen?

Knowing the causes helps you pick the right fix. Fraudulent chargebacks on Shopify come from a short list of sources.

Cause	What is going on	Typical fix
Stolen card use	A criminal buys with a card they should not have	Order review, hold risky orders
Account takeover	A real customer account is used by someone else	Watch for changed addresses and emails
Friendly fraud	The cardholder buys, then disputes	Strong records, clear policies
Family or household use	Another person in the home used the card	Contact the customer first
Name confusion	The statement name differs from your store name	Match the name, send clear receipts
Buyer regret	The customer changes their mind and uses the fraud route	Easy returns, fast support

The last row deserves attention. When a return is hard to arrange or support is slow, some customers pick the dispute route, and a refund request turns into one of the fraud disputes you now have to answer. Making refunds and returns easier is among the cheapest ways to lower your count of fraudulent chargebacks.

How do you write to a customer about a fraudulent chargeback?

The first email matters. Shopify says to contact the customer first, so for fraudulent chargebacks write something that makes it easy for an honest buyer to withdraw and does not accuse anyone.

Subject: Question about order #[number]

Hi [first name],

Our records show an order on [date] for C$[amount], delivered to [city].
We have received notice from the card issuer that this charge was disputed
as unauthorized, and I wanted to check that nothing has gone wrong on our side.

If you recognize the order, or someone in your household placed it, you can
ask your bank to withdraw the dispute. They will give you an official
letter, which you can forward to me.

If you did not place the order, tell me and I will help however I can.
Our statement name is [name]; the receipt email went to [email].

Thank you,
[name], [store], [phone]

Keep a copy of every message. If the customer replies and confirms they made the order, save that email as a PDF. It is direct acknowledgment, and Shopify ranks customer acknowledgment right after direct proof in its evidence order. If the customer agrees but the bank drops the case, the official letter must be on bank letterhead and show the case number, and a screenshot of a bank statement is not enough.

If you cannot reach the customer, or contact looks unsafe, for instance when the email looks stolen, skip it and rely on your records.

What happens after you file a response to fraudulent chargebacks?

Once you submit, the file is closed to changes. Shopify's page says you cannot add more evidence after you respond, and the decision, when it comes, is final. It can take up to 75 days.

Outcome	What happens	What to do next
Won	The amount and fee return in your next payout	Keep the file; the bank can dispute again
Lost	You keep the loss, the fee does not return	Record the cause for your audit
Accepted by you	Same as lost, but chosen	Note why you chose to fold
Missed deadline	Shopify sent saved data only, fee not returned	Fix the process

Use each outcome. For every one of your fraudulent chargebacks, write down the order signals and the cause. After a quarter, the pattern shows whether to tighten order review, adjust a shipping option or change a policy. That review is the heart of a chargeback audit, and it turns a loss into a rule.

What does a fraudulent chargeback really cost a Canadian store?

The headline amount undercounts the damage. A fraudulent chargeback takes the disputed amount and a C$15 or US$15 fee, and on a loss the goods are already gone.

Cost	Detail
Disputed amount	Taken from your balance when filed
Chargeback fee	C$15 or US$15, returned only on a win
Goods shipped	Not recovered on a loss
Shipping paid	Not recovered on a loss
Your time	Hours on evidence
Rate impact	The dispute counts toward your rate, even if you win

A 2026 LexisNexis study, cited by Retail Insider, estimates that every $1 of fraud costs merchants in Canada and the United States about $5.23, up 64% since 2022. The figure covers both countries together, and the article is sponsored content from Interac, so treat it as a rough guide to how costs compound.

If your balance cannot cover the dispute, the shortfall can be debited from your bank account, which is a cash flow problem on top of the loss.

How do you prevent fraudulent chargebacks on Shopify?

Winning fraudulent chargebacks is expensive. Preventing them is cheaper. These steps help, and none needs a large budget.

Order review checklist for fraud risk

[ ] Billing and shipping addresses reviewed when they differ
[ ] IP country compared with billing country
[ ] First time customers with large orders held for a check
[ ] Several cards tried on one order flagged
[ ] Freight forwarder or unusual delivery addresses reviewed
[ ] Any risk indicator Shopify or your apps show is checked before shipping
[ ] A confirmation email goes out with a clear statement name
[ ] High value orders ship with tracking and, where it fits, signature
[ ] Delivery proof saved at delivery, not weeks later

A recognizable name on the statement prevents the Unrecognized reason, one of the two sources of fraudulent chargebacks. Make sure your store name matches what customers know, and that the receipt shows it. A clear confirmation email, with order details and contact information, prevents honest confusion. For high value orders, signature on delivery adds proof that a person received the parcel. Canada Post records the signer's name and signature when the shipper selects the option at shipping.

Preventing fraudulent chargebacks also protects your rate. Visa's excessive line is 1.5% from April 2026 in the US, Canada, the EU and Asia Pacific, according to chargeback.io. Shopify can enrol a store at 1.5% over 90 days, which leads to automatic resolution with a full refund to the customer, no evidence window and a 10% payout reserve. Fraudulent chargebacks feed that count, and winning does not remove them.

How does ChargeFix help with fraudulent chargebacks?

ChargeFix is built for Shopify Payments disputes. For fraud disputes it focuses on assembling the signals into a clear case before the clock runs out.

1. Dispute fetched. ChargeFix fetches the chargeback when it opens, with its reason, amount and due date.
2. Signals gathered. It reads the order, payment details, addresses, tracking and delivery status from your store.
3. Evidence scored. Each item is checked, with a fix beside every gap.
4. Plain verdict. Worth fighting, improve the evidence first or weak evidence.
5. Letter from facts. The response is drafted only from verified facts in your records.
6. You approve. Manual mode is the default. Auto mode, on Starter plans and above, is off until you turn it on and confirm, and its default rule covers product not received with delivery confirmed. Fraud disputes are saved as drafts for you to review.

The verdict is useful for fraudulent chargebacks, because a "weak evidence" result tells you to consider folding before you spend an hour. ChargeFix cannot promise a win, and it does not decide whether the cardholder is honest. It works with Shopify Payments disputes only, and stores minimal data: case ID, amount, reason, status, dates and shop settings, not customer names, addresses, emails or letters.

The free plan covers 2 filings a month, and every paid plan starts with a 14 day trial. The free chargeback cost calculator runs the fight or fold sum for you.

What does a dated plan for a fraud dispute look like?

This plan assumes the shortest window, 7 days.

Day	What you do	Done when
Day 0	Dispute opens. Read the reason and due date.	You know the deadline
Day 1	Pull order signals. Contact the customer if safe.	Triage sheet is filled
Day 2	Decide to fight or fold with the cost sheet.	A decision is written down
Day 3	Gather files: order, fulfillment, tracking, history, replies	Proof is saved as PDF or image
Day 4	Draft the response in Shopify's evidence order	Every claim points to a file
Day 5	Review, compress files to the size limits	Files are under 2 MB each
Day 6	File the response	Confirmation shows in admin
Day 7	Spare day for problems	Nothing left to do
Up to 75 days later	Decision arrives	Note the cause for your audit

What is different about fraudulent chargebacks in Canada?

Most guides are written for the United States. Several points change for a Canadian store on Shopify Payments.

Topic	What applies in Canada	What to do
Shopify Protect	US stores only	Do not count on it for fraud losses
Managed Markets	Shopify's pages differ on how protection applies	Confirm in your own admin
Fee currency	C$15 or US$15 by payout currency	Cost every dispute in your payout currency
Visa line	1.5% from April 2026	Track your rate
Complaints	Code of Conduct for the Credit and Debit Card Industry, supervised by FCAC	Raise a complaint with your processor first
Benchmarks	Mostly US or global	Compare yourself with your own history

Shopify Protect does not apply. It reimburses eligible fraud and unrecognized chargebacks on Shop Pay orders, but only for stores in the United States, and Shopify says it does not constitute insurance. A Canadian store is not eligible, so fraud losses fall on you.

Managed Markets. Shopify's Canada page for Managed Markets says enrolled merchants are automatically enrolled in Shopify Protect on international orders and keep the full payout on chargebacks. Shopify's Help Center says international orders are protected from fraud chargebacks "(United States only)". Because the pages differ, check your admin before relying on either.

Where to complain. Shopify Payments (Canada) acknowledges a complaint within 5 business days and gives a final written decision within 45 days. The Financial Consumer Agency of Canada supervises the Code but is not a dispute resolution agency for individual cases, so it will not reverse a chargeback.

Customer data. Fraud files hold personal information. Share it only with those who need it.

What are the 10 mistakes to avoid with fraudulent chargebacks on Shopify in Canada?

1. Skipping the customer contact. A genuine buyer may drop the dispute.
2. Sending raw data with no story. Explain why the order points to the cardholder.
3. Fighting every case. Fraud disputes win less often than most, so use the cost sheet.
4. Accusing the customer. State records, not suspicions.
5. Forgetting past orders. Undisputed history is your strongest evidence.
6. Saving delivery proof late. Canada Post delivery confirmation is online for 45 days, so save it at delivery.
7. Relying on Shopify Protect. It is US only.
8. Missing the window. There are no extensions, and the fee is not refunded.
9. Ignoring the rate. Fraud disputes count even when you win.
10. Never reviewing causes. Each dispute shows a gap in your order review.

FAQs

What is a fraudulent chargeback on Shopify?

It is a dispute where the cardholder tells their bank they did not authorize the charge, often because the card was stolen. Shopify's evidence rules for fraudulent chargebacks start with the customer. Shopify lists it as Fraudulent, with a related Unrecognized reason for customers who do not recognize the merchant name or location. Both call for similar evidence.

What evidence does Shopify ask for in a fraud dispute?

Shopify says to send the fulfillment date and time, billing information, IP address and country, plus shipping and tracking details. If the customer confirms the purchase, add their statement. Files must be PDF, JPEG or PNG, up to 2 MB each and 4 MB combined.

Can I contact the customer about a fraud dispute?

Yes, and Shopify says to do it first. The customer may have forgotten the purchase, not recognized your name, or had a household member place the order. If they agree the charge is valid, they ask their bank to drop it, and you still submit evidence. Only do this if the order details make it safe.

How often do merchants win fraud disputes?

Fraud coded disputes are the hardest type. One global dataset, from Datos Insights via chargeback.io, puts the merchant win rate at 17%. That is not a Canadian figure, and we have no verified one. Use your own history, and run the fight or fold cost sheet before you spend time.

Does Shopify Protect cover fraud for Canadian stores?

No. Shopify Protect is for US stores only, with a US Shopify Payments account and a US bank account in the business's name. Shopify also says it is not insurance. A Canadian store should rely on its own order review and evidence, and confirm any Managed Markets protection in its admin.

What is friendly fraud?

It is when the cardholder made the purchase, or someone in their household did, and then disputes it anyway. Visa puts it at about 20% of fraudulent disputes, up to 30% for high volume online merchants, according to chargeback.io. Those are global figures. Repeat customers with past undisputed orders are a common sign.

Can Shopify resolve a fraud dispute early?

Not for every type. Shopify says it cannot request early resolution for American Express disputes or for Visa disputes with a Fraudulent reason code. In those cases, build a complete response before the due date, because you cannot add evidence after you file.

Does winning a fraud dispute remove it from my rate?

No. Shopify says a resolved dispute still counts toward your dispute rate, and a won chargeback can be disputed again. Visa's excessive line is 1.5% from April 2026, and Shopify can enrol a store at 1.5% over 90 days. Prevention is the way to lower the count.

How does ChargeFix help with fraudulent chargebacks?

ChargeFix fetches the dispute, reads your order, addresses, tracking and delivery status, scores the evidence with a fix beside every gap, and drafts the letter from verified facts. A weak evidence verdict can tell you to fold early. It cannot guarantee a win, and it handles Shopify Payments disputes only.

Should I fight every fraudulent chargeback?

No. Use the cost sheet: compare your honest chance of winning times the total loss against the time you would spend. Fight repeat customers with matching signals and large orders. Consider folding on small orders with weak signals, remembering that accepting still costs the amount, the fee and the goods.
