How To Protect Yourself Against Credit Card Fraud in Canada?

Q: What are the most common ways credit card data gets stolen?

The five biggest threats are: phishing emails impersonating banks or retailers, unsecured public Wi-Fi with packet-sniffing software, large-scale data breaches at merchants you have shopped with, spyware and malware on personal devices, and old-school dumpster diving for paper statements. Phishing remains the dominant vector in 2026 because attackers can now use AI to mimic legitimate brands convincingly, so always verify URLs and never click links inside unexpected emails about your account.

Q: What should I do the moment I spot a fraudulent charge?

Take three immediate steps. First, call your card issuer using the number on the back of your card to flag the transaction and freeze the account. Second, request a card replacement with a new number; never accept a reissued card with the same number. Third, file a police report in the jurisdiction where the fraud appears to have occurred (especially if the loss is large or part of identity theft). Following up with Equifax and TransUnion to add a fraud alert is also a good precaution.

How To Protect Yourself Against Credit Card Fraud in Canada?

One of the biggest nightmares is finding out that your credit card number has been stolen. You could end up with fraudulent charges that will require lots of time on the phone with your credit card company to straighten out.

That’s why it is important to protect yourself from all types of credit card fraud. Here is a look at the various ways that your credit card can be stolen, how to protect yourself and what to do if you find out that you have been a victim.

Ways Your Credit Card Information May Be Stolen

There are five major ways that your credit card information can be stolen. Here’s a look at some of the top ways bad guys can get a hold of your credit card information:

1) Phishing emails

A phishing email is an email where an email will pretend to be from a legitimate company.

This company may have a link that will prompt you to enter your credit card information. For instance, you may get a letter from a major company like eBay or Amazon saying that your order is on hold due to a declined credit card. The link will send you to an impersonated webpage, prompting you to enter your credit card information.

Be sure to check the website’s web address to ensure that it is from a legitimate company.

2) Public Wi-Fi

You may use public wi-fi at a restaurant or a hotel.

However, you should avoid using these public wi-fi connections to enter your credit card information. That is because some people can use special « snooping » software to gather your credit card information and steal it.

3) Data breach

Every once in a while, a large company will have its information stolen. That information may include your credit card information.

If you receive a notice from a company that your information may have been compromised in a data breach, immediately check your credit card for any fraudulent charges.

4) Spyware and malware

A criminal may infect your computer with something known as malware or spyware. With these pieces of software, a criminal can record your keystrokes and be able to gather your credit card information. Spyware or malware is usually delivered to your computer by opening emails sent by the criminal.

Never open an email from someone whom you do not know.

5) Dumpster diving

Some criminals will resort to dumpster diving to grab credit card statements or other information that may have your credit card information.

Be sure to rip up any papers that have any of your financial information. If you want to be even safer with your information, run your financial paperwork through a shredder before discarding it.

How to protect yourself from credit card fraud

We discussed the many ways that criminals can get your credit card information. Now, here are 10 simple steps that you can take to avoid becoming a victim of credit card fraud:

1) Avoid answering suspicious emails

Avoid answering emails with salacious headlines or promises of money or contest winnings. Also, avoid opening emails that appear from addresses that you are unfamiliar with.

Mark these emails as spam so the sender will not be able to deliver another email.

2) Avoid entering credit cards on public wi-fi networks

Instead of entering your credit card on a public wi-fi network, wait until you get home.

You can also call the company to tell them your credit card information.

3) Rip up your credit card statements and ATM receipts

Be sure to destroy any information that would have your credit card information on it. This information can include the following:

Credit card statements
ATM receipts
Sales receipts
Financial budgeting information

4) Never enter your credit card through an unsecured website

Ensure that a website has an HTTPS address and a security certificate before entering your credit card information.

Also, never visit a website if your browser warns you that the site is not safe.

5) Never sign a blank receipt

If someone asks you to sign a receipt for a purchase, make sure you can clearly read the amount. Never sign a blank receipt. Someone can place any amount on the receipt, and it could end up looking legitimate.

6) Never give your credit card number over the phone to someone who you don’t know

Avoid handing over your credit card information to someone unfamiliar to you. The only things a person needs to make a purchase are:

your name
your credit card number
the card’s expiration date
the three digital codes on the back of the credit card

7) Check your credit card transactions often

Be sure to check your credit card transactions often to make sure that no one is making any fraudulent purchases.

You can check recent transactions on your online account or call the customer service number on the back of the card.

8) Never write your credit card number on a piece of paper or online

Avoid writing your credit card on any piece of people. Also, avoid writing your number on an online document where it can be seen and stolen.

9) Keep your credit cards in a secure place

Be sure to keep your credit cards in a secure place.

If you are at a hotel, you can place the cards in the room’s safe or ask the front desk for their safety deposit box.

10) Don’t use an ATM or gas station pump that appears unsafe

Be sure to avoid inserting your credit card in an ATM or gas station credit card slot that appears to have been tampered with.

What to do if you are a victim of credit card fraud

If you have been a victim of credit card fraud, you can follow these three steps to get the charges potentially removed from your card.

1) Report any questionable charges to your credit card issuer

Call the customer service number on the back of your card and report any questionable charges. Most credit card companies should be able to cancel those transactions if you report them within 30 or 60 days of the purchase.

2) Cancel your credit card

If your card has been lost or stolen, call the credit card company and cancel the card. The credit card company should be able to send you a new card, with a new number, in a couple of days.

3) File a police report

You may have to file a police report. Be sure to file the police report in the jurisdiction where the credit card was stolen.

Staying safe from credit card fraud

You don’t have to be a victim of credit card fraud. Be sure to protect your credit card and credit information, check your statement regularly and immediately report any suspicious charges.

With the right vigilance, your credit card information can remain safe.

Frequently Asked Questions about credit card fraud protection in Canada

Here are frequently asked questions in the milesopedia community about this card.

Am I liable for fraudulent charges on my Canadian credit card?

In most cases, no. Major Canadian issuers including Visa, Mastercard and American Express offer zero liability protection on unauthorized transactions, provided you report the fraud promptly and have not been negligent (sharing your PIN, for example). Most banks ask that you flag suspicious charges within 30 to 60 days of the statement date. Once reported, the issuer cancels the card, refunds the disputed amounts and issues a new card with a new number, usually within 5 to 7 business days.

What are the most common ways credit card data gets stolen?

The five biggest threats are: phishing emails impersonating banks or retailers, unsecured public Wi-Fi with packet-sniffing software, large-scale data breaches at merchants you have shopped with, spyware and malware on personal devices, and old-school dumpster diving for paper statements. Phishing remains the dominant vector in 2026 because attackers can now use AI to mimic legitimate brands convincingly, so always verify URLs and never click links inside unexpected emails about your account.

Following up with Equifax and TransUnion to add a fraud alert is also a good precaution.

How can I prevent credit card fraud day to day?

Apply 10 layered habits: avoid suspicious emails, only enter card info on HTTPS pages, never sign blank receipts, watch your card during in-person transactions, shred paper statements, monitor your transactions weekly, never write your card number on shared documents, store cards in an RFID-blocking sleeve, inspect ATMs for skimmers before inserting your card, and enable instant transaction alerts in your bank app. Together these reduce your fraud risk by an order of magnitude with minimal daily effort.

Point accumulation on grocery and restaurant spending depends on the total gross monthly amount charged to the credit card account, across all categories. Earn 5 points per dollar spent on eligible grocery and restaurant purchases. The 5 points per dollar accumulation is valid for the first $2,500 of gross monthly purchases charged to the account. Beyond this amount, eligible grocery and restaurant spending will earn 2 points per dollar. The calculation of the gross monthly purchase amount is based on monthly billing. A grocery purchase means a purchase made at a merchant whose primary business is selling food, such as a grocery store, delicatessen, supermarket, fruit store, or specialty food store. Meal kit subscriptions and meal delivery services are eligible. Therefore, this definition excludes, among others, retail stores and big-box stores whose primary business is selling non-food items. Some merchants may sell products or services identical or similar to those of eligible merchants, or are separate merchants located on the same premises as eligible merchants, but are classified by Mastercard in different categories. Purchases made from other merchants only earn base reward points. A restaurant purchase means a purchase made at a restaurant, including quick-service restaurants, bars, discotheques, nightclubs, and taverns. To view the full list of Mastercard codes associated with eligible merchants, download the À la carte Rewards Plan^® terms and conditions document.
These protections apply if the purchases or rental are paid for in part with the card before departure, except, if applicable, for out-of-province medical-hospital insurance for which it is not necessary to charge the purchase of an à la carte trip and for baggage delay protection where the full cost of transport must have been charged to the card. All these protections apply to the primary cardholder, their spouse and/or their dependent children when they (spouse and dependent children) travel with the cardholder. Extended warranties apply to most new items purchased with the card, in Canada or abroad, provided the manufacturer’s warranty exists and is valid in Canada. Certain conditions, limitations and restrictions apply. For more information and details regarding your insurance coverage, please consult the insurance certificate linked to your card.
Subject to credit approval by National Bank.
Certain conditions apply. Visit mastercard.ca for more information. See all credit card terms and conditions.
To earn 2 points per dollar spent, you must pay for your gas or electric charging purchases at a gas station or certain big-box stores. Some merchants may sell products or services identical or similar to those of eligible merchants, or are separate merchants located on the same premises as eligible merchants, but are classified by Mastercard in different categories. Purchases made from other merchants only earn base reward points. To view the full list of Mastercard codes associated with eligible merchants, download the À la carte Rewards Plan^® terms and conditions document.
Recurring bill payments are defined as payments made monthly or regularly that are automatically charged by the merchant to your National Bank World Elite Mastercard. Not all merchants offer recurring payments, and not all recurring payments are considered recurring bill payments. Therefore, some payments may not qualify for accelerated reward points.
To earn 2 points per dollar spent, you must pay for your eligible purchases through the À la carte Travel^TM agency section of our À la carte Rewards^TM site.
For example, if you spend $400 monthly on groceries, $200 on gas, $100 on recurring bills and $150 on other purchases, the $850 spent will generate 2,750 points, broken down as follows: 2,000 points for grocery spending (since the total gross monthly amount is $850, which is less than $2,500), 400 points for gas spending, 200 points for recurring bills and 150 points for other purchases.
Insurance up to $1,000 in case of breakage, loss or theft of mobile devices for a maximum period of 2 years following the date of purchase. Subject to purchasing the device with the National Bank World Elite Mastercard or a phone service subscription paid by recurring payments from your National Bank Platinum Mastercard starting September 1, 2022. For all conditions, please consult the insurance certificate linked to your card.
