Losing your debit card is stressful, but acting quickly can prevent unauthorized charges and minimize any financial damage. Here is exactly what to do.
Step 1: Lock or Cancel the Card Immediately
Fastest option — your bank’s app:
Most major Canadian banks now have card lock/freeze features in their mobile apps. Open the app, navigate to card management, and lock or cancel the card:
- RBC: My Cards → Lock Card
- TD: MyCards → Lock/Unlock
- BMO: Manage Cards → Lock Card
- Scotiabank: Card Management → Pause Card
- CIBC: Manage Cards → Lock Card
- Tangerine: Manage Cards → Freeze Card
- EQ Bank: Account Settings → Card Controls
Locking the card (if your bank offers a temporary lock vs. permanent cancellation) blocks new transactions while you look for the card. If you find it, you can unlock it. If not, proceed to permanent cancellation and replacement.
If you don’t have app access — call your bank:

| EQ Bank | 1-844-437-2265 |
| Desjardins | 1-800-363-3380 |
These lines are available 24/7 for lost and stolen card reports.
Step 2: Review Recent Transactions
Immediately after cancelling the card, check your account transactions for any unauthorized activity:
- Look for transactions you do not recognize
- Pay attention to small test charges (fraudsters often make a small purchase first to verify a card works before making larger ones)
- Check your balance for unexpected reductions
Step 3: Report Unauthorized Transactions
If you see transactions you did not make, report them to your bank at the same time you report the card lost/stolen. Ask your bank to open a dispute for each unauthorized transaction.
Your liability under Canadian banking rules:
Under the Canadian Bankers Association’s voluntary Code of Practice for Consumer Debit Card Services, if you:
- Report the loss promptly
- Did not contribute to the loss (no PIN written on the card, no PIN shared with others)
- Did not act with gross negligence
Then your bank is responsible for reversing unauthorized transactions that occurred after the card was lost (and in some cases, even shortly before you were aware of the loss).
Keep a record of:
- When you last used the card
- When you noticed it was missing
- The time and date you reported it to the bank
Step 4: Request a Replacement Card
After cancelling the card, your bank will issue a replacement. Options depend on the bank:
Same-day replacement at a branch:
- RBC, TD, BMO, Scotiabank, and CIBC can issue replacement cards at most branches on the same visit
- Bring government-issued photo ID
Mailed replacement (5–10 business days):
- Online banks (Tangerine, Simplii, EQ Bank, KOHO) mail replacement cards only
- Ask for expedited delivery if available
Temporary card number:
- Some banks can provide a temporary virtual card number for online purchases while you wait for the physical replacement
Step 5: Update Automatic Payments
Your new debit card will have a new card number. If you have automatic payments linked to your debit card (which is less common than credit card autopay, but occurs with some subscriptions), update those accounts with your new card number once it arrives.
Common places to check:
- Streaming services
- Gym memberships
- Recurring donations
What Happens to Pre-Authorized Payments Linked to Your Account
Pre-authorized debits (PADs) linked to your bank account number and transit/institution number (not to the card number) are not affected by a new debit card. Your mortgage payment, utility bills, and insurance premiums linked to your account will continue uninterrupted.
Only payments tied to the physical card number itself (which is typical of online subscriptions using debit-as-credit) need to be updated.
Can Someone Use Your Lost Debit Card Without Your PIN?
In-person purchases: Traditional debit transactions in Canada require a PIN — so someone who finds your card cannot complete a standard debit purchase without your PIN.
Contactless (tap) transactions: Many Canadian debit cards support contactless payments. Tap purchases under $250 (the standard limit) do not require a PIN. A finder could potentially make tap purchases up to the contactless limit before the card is cancelled. This is one reason why immediate cancellation matters.
Online purchases: Debit card numbers can be used for online purchases at merchants that accept debit-as-credit (e.g., Visa Debit or Debit Mastercard). These do not require a PIN. If your card is a Visa Debit or Debit Mastercard, online fraud is possible without your PIN — cancel the card immediately.
