Online marketplaces make it easier than ever to buy and sell everything from furniture and electronics to vehicles and collectibles. Unfortunately, they've also become a popular target for fraudsters. Whether you're shopping on Facebook Marketplace, Kijiji, eBay, or another online platform, knowing how marketplace scams work can help you protect your money and personal information.

Here's a few tips for how to recognize the most common marketplace scams in Canada—and what you can do to avoid becoming a victim.

What are marketplace scams?

Marketplace scams occur when criminals use online buying and selling platforms to trick people into sending money, sharing personal information, or handing over valuable items without receiving what was promised. Scammers often rely on urgency, fake identities, and deals that seem too good to pass up.

The most common online marketplace scams

Fake listings

One of the most common scams involves fake listings for products that don't actually exist. Scammers often advertise popular items at unusually low prices to encourage buyers to act quickly. After receiving payment, they disappear without shipping the item.

Red flags:

  • Prices significantly lower than similar listings
  • Poor-quality or stock photos
  • Seller refuses to answer questions
  • Requests payment before viewing the item
Overpayment scams

If you're selling an item, a scammer may send a fake cheque or claim they've accidentally overpaid you. They'll ask you to refund the difference before the original payment clears. Once the payment is found to be fraudulent, you're responsible for the money you refunded.

E-transfer and payment scams

Fraudsters may claim they have already sent an Interac e-Transfer® payment and ask you to click a fake deposit link. Others may send fake payment confirmation emails that appear legitimate. Always verify payments directly through your online banking before releasing an item.

Phishing scams

Scammers may send links pretending to verify your account or confirm a shipment.

These links often lead to fake websites designed to steal:

  • Banking credentials
  • Marketplace login information
  • Credit card details
  • Personal information

Never log in through links sent by strangers.

Shipping scams

Some fraudsters convince buyers or sellers to ship items before payment has been confirmed. Others ask to communicate outside the marketplace platform to avoid buyer protections. Whenever possible, use the platform's official messaging and payment tools.

Counterfeit products

Luxury goods, electronics, designer clothing, and event tickets are frequently counterfeited. If the price seems dramatically lower than retail, there's a good chance the item isn't authentic.

How to protect yourself when buying or selling online

Taking a few extra precautions can significantly reduce your risk.

Research the buyer or seller

Before completing a transaction:

  • Review ratings and reviews
  • Check account history
  • Look for verified profiles
  • Search for previous scam reports if something feels suspicious
Use secure payment methods

Whenever possible:

  • Pay with secure payment methods that include buyer protection.
  • Avoid wire transfers or payment methods that cannot be reversed.
  • Never send money simply to "hold" an item.
Meet safely

If meeting in person:

  • Choose a public location.
  • Meet during daylight hours.
  • Bring a friend if possible.
  • Trust your instincts if something doesn't feel right.

Some police services offer designated safe exchange zones for online marketplace transactions.

Verify listings carefully

Be cautious of:

  • Prices that seem too good to be true
  • Sellers who refuse to provide additional photos
  • Requests to move conversations to private messaging apps immediately
  • Pressure to act quickly

Protect your personal information

Never share:

  • Online banking passwords
  • Debit card PINs
  • One-time verification codes
  • Social Insurance Numbers (SIN)
  • Copies of government-issued identification unless absolutely necessary

What should you do if you've been scammed?

If you believe you've been the victim of a marketplace scam:

Contact your financial institution immediately

If you've shared banking information or sent a payment, contact your financial institution as soon as possible. Acting quickly may help limit financial losses.

Report the scam

Report the incident to:

  • The marketplace where the transaction occurred
  • Your local police service (if significant financial loss occurred)
  • The Canadian Anti-Fraud Centre

Reporting scams helps protect others and allows authorities to track emerging fraud trends.

Change your passwords

If you clicked a suspicious link or shared login credentials:

  • Change your passwords immediately.
  • Enable multi-factor authentication (MFA).
  • Monitor your financial accounts for unauthorized activity.

Tips for safer online shopping and selling

Follow these best practices every time you use an online marketplace:

  • Compare prices before purchasing.
  • Verify payments before releasing an item.
  • Keep conversations within the marketplace platform whenever possible.
  • Be skeptical of urgency or pressure tactics.
  • Trust your instincts—if something feels wrong, walk away.

The bottom line

Online marketplaces are a convenient way to buy and sell, but scammers are constantly developing new ways to deceive buyers and sellers. Staying informed, verifying payments, protecting your personal information, and using secure payment methods can significantly reduce your risk of fraud.
