Is it better to use a credit card or debit card in Canada?

Credit cards are better for most purchases — they offer rewards (1-5% back), stronger fraud protection, and purchase insurance. Use debit for ATM withdrawals and when a vendor charges credit card surcharges.

Are credit cards safer than debit cards?

Yes. Credit card fraud is covered by zero-liability policies and disputed charges don''t affect your bank balance. Debit card fraud takes money directly from your account and can take weeks to resolve.

Should I use my debit card for online shopping?

No. Always use a credit card for online purchases. Credit cards offer stronger fraud protection and zero-liability guarantees. If your credit card number is stolen, your bank account is not affected.

With a credit card, you dispute the charge and your bank account is untouched.
