Module 23

Buying and Selling Online Safely

⏱ About 25–35 minutes — go at your own pace

Frank, 74, wanted to sell his late wife's sewing machine. He listed it for $50 on an online marketplace. Within an hour he got three messages. The first asked him to accept payment by e-transfer and ship the machine to another province. The second offered $200 if Frank clicked a link to "verify his account." The third was a real person from his town who wanted to come see the sewing machine in person. Frank could not tell which was safe.

If you have ever felt unsure about buying or selling something online, you are not alone. Online marketplaces can be wonderful tools for finding deals and clearing out items you no longer need — but they also attract scammers. This module will teach you exactly how to tell the difference and protect yourself.

You are in a safe place. This module is about building your confidence so you can use online marketplaces without worry. We will walk through every step together — and by the end, you will know exactly what to watch for.

1. Frank's Three Messages

Let us go back to Frank and look at each of those three messages carefully. Learning to read these messages is the most important skill you will gain in this module.

🚩 Message 1 — The Overpayment and Shipping Scam

This person asked Frank to accept payment by e-transfer and ship the sewing machine to another province. The red flags here are:

  • They want the item shipped far away — no intention of meeting in person
  • They want to pay before seeing the item — real local buyers want to inspect first
  • Once Frank ships the item, the "buyer" could reverse the e-transfer or it could turn out to be fraudulent — and Frank would have no item and no money

Verdict: This is a scam. Do not respond.

🚩 Message 2 — The Phishing Link Scam

This person offered $200 for a $50 item — and asked Frank to click a link to "verify his account." The red flags here are:

  • Offering far more than the asking price — no real buyer does this
  • Asking Frank to click a link — this link likely leads to a fake website designed to steal his personal information or banking details
  • Asking to "verify an account" — legitimate marketplaces never ask buyers or sellers to verify accounts through links in messages

Verdict: This is a phishing scam. Do not click the link. Do not respond. Report the message.

✅ Message 3 — The Real Buyer

This person is from Frank's town and wants to come see the sewing machine in person. The green flags here are:

  • They are local — they live nearby and can meet face to face
  • They want to see the item before paying — this is what real buyers do
  • No links, no unusual offers, no pressure to act quickly

Verdict: This is likely a genuine buyer. Frank should arrange to meet in a safe, public place.

Confidence check: You now know the three most common types of marketplace messages. The pattern is simple — real buyers are local, want to see the item, and do not send links or offer more than the asking price.

2. How Online Marketplaces Work

An online marketplace is a website or app where ordinary people can list items for sale and other people can browse and buy them. Think of it like a community bulletin board at your local library — but available to anyone with an internet connection.

Here is how it typically works: you take a few photos of an item, write a short description, set a price, and post the listing. People in your area (or farther away) can see your listing, send you a message, and arrange to buy it. Most listings are free to post.

⚠️ What the Platform Does NOT Do

This is the most important thing to understand: the marketplace platform does not verify buyers or sellers. It does not check whether a buyer is trustworthy, whether their money is real, or whether they intend to follow through. The platform is simply a meeting place — the responsibility for staying safe falls on you.

That might sound scary, but it does not have to be. With a few simple habits — which we will cover in this module — you can use online marketplaces safely and confidently.

Confidence check: Online marketplaces are useful tools — millions of Canadians use them every day. The key is knowing that the platform does not protect you, so you need to protect yourself. And that is exactly what this module teaches.

3. Buying Safely

Buying something from an online marketplace can save you real money — furniture, tools, kitchen appliances, and hobby supplies are often listed at a fraction of the retail price. But you need to follow a few simple rules to make sure the transaction goes smoothly and safely.

🛡️ The Safe Buying Checklist

  • Always meet in a public place — a coffee shop, a shopping centre parking lot, or your local police station lobby. Many police stations in Ontario have designated "safe exchange zones" for exactly this purpose.
  • Bring someone with you — a friend, a family member, or a neighbour. There is safety in numbers, and it discourages anyone with bad intentions.
  • Pay with cash or e-transfer on the spot — never pay before you see the item. Never send money through a link the seller provides. Never use gift cards or cryptocurrency as payment.
  • Inspect the item carefully before handing over money — test it if possible. If it is electronic, ask to see it turned on and working.
  • If a deal seems too good to be true, it probably is — a brand-new item listed at 80% off retail price is almost certainly a scam or a counterfeit.

Confidence check: The golden rule of buying on a marketplace is simple — see the item in person, in a public place, before you pay. If you follow this one rule, you avoid the vast majority of scams.

4. Selling Safely

Selling items you no longer need is a wonderful way to declutter and earn a little extra money. Whether it is furniture, kitchen items, tools, or hobby supplies, online marketplaces make it easy to find buyers in your area. Here is how to do it safely.

📸 Creating a Good Listing

  • Take clear, well-lit photos — natural daylight works best. Take photos from several angles so buyers can see the full item.
  • Write an honest description — mention any scratches, dents, or signs of wear. Honesty builds trust and prevents disputes.
  • Set a fair price — before listing, search for similar items on the marketplace to see what they are selling for. Price yours in the same range.

🔒 Protecting Your Privacy When Selling

  • Never include your home address in the listing — do not take photos that show your house number, street name, or other identifying details.
  • Accept cash or e-transfer only — do not accept cheques, money orders, or payment through unfamiliar apps.
  • Meet in a public place — just like buying, selling should always happen in a safe, public location. Never invite a stranger to your home.
  • Tell someone where you are going — let a friend or family member know you are meeting a buyer, where you are going, and when you expect to be back.

Confidence check: Selling online is straightforward once you know the basics. Clear photos, an honest description, a fair price, and meeting in public — that is all you need.

5. The Scam Spotting Checklist

Scammers follow predictable patterns. Once you know what to look for, spotting them becomes much easier. Keep this checklist in mind every time you receive a message from a buyer or seller on an online marketplace.

🚩 Red Flags — If You See Any of These, Walk Away

  • They want to move the conversation off the platform — for example, they ask you to text them, email them directly, or message them on a different app. Legitimate buyers and sellers are happy to communicate through the marketplace.
  • They offer more than the asking price — no real buyer offers $200 for a $50 item. This is always a setup for a scam.
  • They send you a link — whether it is to "verify your account", "confirm payment", or "see another listing". Never click links in marketplace messages.
  • They request personal information — your date of birth, banking details, social insurance number, or home address. A buyer only needs to know where to meet you in public.
  • They will not meet in person — if someone insists on shipping, paying remotely, or using a third party to pick up the item, be very cautious. Genuine local buyers are willing to meet face to face.
  • They pressure you to act quickly — "I need to buy this today" or "I'm sending payment right now, please hold it." Scammers create urgency to stop you from thinking clearly.

Confidence check: You do not need to memorise this list. The simple rule is: if something feels off, trust your instincts. You can always say no, stop responding, or block the person. You are in control.

6. E-Transfer Safety

Interac e-Transfer is one of the safest ways to pay or get paid for marketplace transactions — when used correctly. It is built into Canadian banking and most banks offer it for free. But there are important rules to follow.

💰 How Interac e-Transfer Works for Marketplace Sales

When a buyer sends you an e-transfer, the money moves from their bank account to yours through Canada's Interac network. Here is the safe way to use it:

  1. Meet the buyer in person at a public location
  2. Let the buyer inspect the item
  3. Have them send the e-transfer while you are together
  4. Open your own banking app and verify that the money has arrived in your account — do not rely on a screenshot the buyer shows you
  5. Only hand over the item once you have confirmed the money is in your account

⚠️ E-Transfer Safety Rules

  • Set a security question if your bank requires one — choose a question and answer that only you and the buyer know. Share the answer in person, not by message.
  • Never accept a screenshot as proof of payment — screenshots can be faked in seconds. Always check your own banking app to confirm the money has arrived.
  • If you have auto-deposit enabled, the e-transfer will go straight into your account — you will see it immediately. If not, you will need to accept the transfer using the security question answer.

Confidence check: The key rule with e-transfers is simple — always verify payment in your own banking app before handing over the item. Never trust a screenshot. If the buyer cannot send the e-transfer on the spot, ask them to bring cash instead.

7. Shipping: When and How

Most marketplace transactions work best when you meet in person. But sometimes shipping makes sense — for example, if you are selling a small, lightweight item to someone in another city. The key is knowing how to do it safely.

📦 The Safe Shipping Rule

Only ship using the marketplace platform's built-in shipping feature — if the platform offers one. This built-in shipping typically provides:

  • Tracking numbers so both you and the buyer can see where the package is
  • Buyer and seller protection — if the item does not arrive or is not as described, the platform may issue a refund
  • Payment held in escrow — the platform holds the buyer's money until the item is delivered, protecting both parties

🚫 Never Do This

  • Never ship an item and trust the buyer to pay later — once the item is gone, you have no leverage
  • Never ship outside the platform's system because a buyer asked you to — this removes your protection
  • Never ship to an address that differs from what the platform shows — scammers often ask you to ship to a different address after the sale

Confidence check: If you are not comfortable with shipping, you do not have to do it. It is perfectly fine to list your items as "local pickup only." Most marketplace buyers prefer meeting in person anyway.

8. What to Do If Something Goes Wrong

Even with all the right precautions, things can sometimes go wrong. If you believe you have been scammed or something does not feel right about a transaction, here is exactly what to do — step by step.

📋 Step-by-Step: What to Do

  1. Stop all communication with the person — do not respond to any more messages. Engaging further gives scammers more opportunities to manipulate you.
  2. Block the person on the marketplace platform — this prevents them from contacting you again.
  3. Report the person to the marketplace platform — every marketplace has a "Report" button on listings and messages. Use it. This helps protect other people too.
  4. Report the scam to the Canadian Anti-Fraud Centre — call 1-888-495-8501 or visit antifraudcentre-centreantifraude.ca. They track fraud across Canada and your report helps them catch scammers.
  5. If you sent money, contact your bank immediately — your bank may be able to reverse or flag the transaction, especially if you report it quickly.

💙 It Is Not Your Fault

If you have been scammed, please know this: it is not your fault. Scammers are professional criminals who target people of all ages. Reporting what happened takes courage and helps protect others. You should feel proud, not embarrassed, for speaking up.
