By CanadianBankNews Editorial Team - Published 2026-07-12 - Last updated 2026-07-12
AI Summary
If scammers drain your account, your bank's responsibility depends on whether the transaction was unauthorized, whether you protected credentials, how quickly you reported it, and what the investigation finds. Start by freezing access, preserving evidence, reporting the fraud, and asking for a written decision.
Key takeaways
- Unauthorized transactions and authorized payment scams are treated differently.
- Report suspicious activity to your bank immediately and keep the case number.
- Reimbursement depends on the bank's investigation and the facts of the case.
- If you disagree with the bank's decision, escalate through the bank, then OBSI where eligible.
Can your bank be responsible after scammers drain your account?
Sometimes, but not always. Canadian banks usually investigate disputed transactions and may reimburse losses when a payment was unauthorized and the customer took reasonable care. Authorized scams are more complicated because the customer was tricked into approving the payment. The practical goal is to report fast, preserve evidence, force a clear written decision, and escalate if the bank's answer does not match the facts.
This guide is not legal advice and does not promise reimbursement. It explains the process Canadians can follow and the evidence that often matters.
Key takeaways
- Unauthorized fraud and authorized payment scams are treated differently.
- Speed matters: notify the bank without delay and ask for the fraud case number.
- Banks should investigate disputed transactions, but reimbursement depends on the circumstances.
- If the bank denies reimbursement, ask for the written reason and complaint escalation path.
When Canadian banks may reimburse fraud losses
Reimbursement depends on the product, the payment method, whether the transaction was authorized, how credentials were protected, and how quickly the customer reported the problem. Use this table to frame the bank's investigation.
| Scenario | Example | What the bank reviews | What can weaken the claim |
|---|---|---|---|
| Unauthorized card transaction | A stolen card number or compromised card is used without your permission. | The bank or card issuer should investigate. Card network policies and federal rules may limit your liability if you acted responsibly and reported quickly. | Higher risk if the bank finds gross negligence, shared PINs/passwords, delayed reporting or ignored alerts. |
| Unauthorized debit or account access | Someone accesses online banking or uses a debit credential without permission. | The bank should investigate the transaction, including how authentication was used and whether circumstances were beyond your control. | Higher risk if credentials were shared, reused, written down or reported late. |
| Authorized payment scam | A scammer impersonates a bank, government agency, buyer, seller, family member or investment contact and persuades you to send money. | Reimbursement is less predictable because the payment was authorized. The bank may review warnings, account history, transfer controls and whether it could reasonably intervene. | Higher risk when funds were willingly sent, moved to crypto, wired abroad or withdrawn as cash. |
| Credential theft after phishing | You entered banking details into a fake website or gave a code to someone posing as the bank. | The bank will usually examine how credentials were obtained, whether alerts were sent and whether reasonable security steps were followed. | Higher risk if one-time codes, passwords or PINs were shared with the scammer. |
What to do immediately after discovering bank fraud
- 1Call your bank's fraud department and ask it to freeze affected cards, online banking access and transfers.
- 2Change passwords and security questions from a trusted device, then turn on multi-factor authentication where available.
- 3Save evidence before deleting messages, emails, call logs, screenshots or payment confirmations.
- 4Report the fraud to local police and the Canadian Anti-Fraud Centre.
- 5Ask the bank for a case number, expected timeline and written explanation if reimbursement is denied.
How to escalate a fraud complaint
Step 1
Start with the bank
Open a fraud claim, ask what evidence is needed, and keep the case number. If the first representative cannot resolve it, ask for escalation through the bank's complaint process.
Step 2
Ask for the written decision
If reimbursement is denied or delayed, ask for the detailed written response and the bank's final position. Keep dates and names from every interaction.
Step 3
Escalate externally if needed
For banks, complaints can generally go to OBSI after the bank provides a final written response or after the complaint timeline expires. FCAC says banks have a maximum of 56 days to deal with a complaint.

Frequently asked questions
Will my Canadian bank reimburse money lost to fraud?
It depends on the facts. Banks and card networks usually provide stronger protection for unauthorized credit or debit transactions, but authorized payment scams are often harder because the customer was persuaded to send the money. Report the issue immediately and ask for a written decision.
What is the difference between unauthorized fraud and an authorized payment scam?
Unauthorized fraud is a transaction you did not approve, such as stolen card use or account access. An authorized payment scam happens when a criminal tricks you into approving a transfer, e-transfer, bill payment or wire. The bank's investigation may treat these differently.
What should I do first if money disappears from my account?
Contact your bank immediately, freeze affected cards or online banking access, change passwords from a clean device, collect evidence, file a police report if money was stolen, and report the fraud to the Canadian Anti-Fraud Centre.
Can I take a bank fraud complaint to OBSI?
For a bank complaint, you can generally escalate to OBSI after the bank gives a final written response or after the bank's complaint timeline has expired. OBSI reviews unresolved banking complaints, but it does not guarantee reimbursement.
What evidence helps a bank fraud investigation?
Keep transaction records, screenshots, text messages, emails, caller IDs, URLs, police report numbers, CAFC report details, bank case numbers, dates, names of representatives, and notes from every call.
Compare your bank's profile before you escalate
Bank profile pages can help you find official banking, credit card and complaint links before you call or write your escalation letter.
Build your fraud complaint file
Before calling again, organize the transaction details, screenshots, report numbers and the exact resolution you want from the bank. A clear timeline makes escalation easier.
