A private sale feels finished once the buyer drives away with cash or an e-transfer in hand, and legally, ownership has transferred through the signed bill of sale. But that’s not the end of your connection to the vehicle from a registration standpoint. It can still appear under your name in Alberta’s records until the buyer registers it.
Most of the time that gap closes within a day or two. The exception is a buyer who benefits from it staying open: a curbsider, an unlicensed operator posing as an ordinary private buyer, sometimes asking you to leave part of the paperwork incomplete. Selling to one can mean your name stays attached to a vehicle you no longer own, long after the sale.
This guide covers what a curbsider is, the blank-registration trap used against sellers, the warning signs to watch for, and what protects you.

What Is a Curbsider in Alberta?
A curbsider, or “curber” in Alberta Motor Vehicle Industry Council terminology, is someone selling vehicles as a business without the AMVIC licence that business legally requires, while posing as an ordinary private seller to avoid scrutiny.
AMVIC’s own description is direct about the pattern: curbers often deal in vehicles with hidden problems, damage, odometer tampering, or unclear history, since operating outside the licensing system means skipping the disclosure obligations a real dealer has to meet. Consumers who buy from them lose access to AMVIC’s Compensation Fund entirely, since that protection only applies to transactions with licensed businesses.
Most curbsider coverage focuses on this buyer-side risk. What gets less attention is that curbsiders are just as often on the other side of the transaction, buying from private sellers specifically because a seller who thinks they’re dealing with an ordinary buyer won’t ask the questions a licensed dealer would expect.
The Blank-Registration Trap When Selling a Car
This is the part that catches sellers off guard, and it’s specific to how Alberta’s registration system actually works.
In Alberta, a signed bill of sale is what actually transfers ownership of the vehicle, not the registration record. Registration is a separate administrative step: the buyer must arrange it before legally driving the vehicle on Alberta roads, but nothing forces them to do it on any specific timeline relative to the sale itself. A curbsider buying from a private seller has a specific reason to delay or skip that registration step entirely: if they never register the vehicle in their own name, they never appear anywhere in its registration history.
They can hold it briefly, or flip it to someone else immediately, without their name ever touching that record. Some go further and ask the seller directly to leave portions of the transfer paperwork incomplete, framed as a convenience or a favor, when the actual purpose is to keep themselves invisible in that record entirely.
What this means for you as the seller is straightforward and uncomfortable: until someone actually completes that registry visit, you remain the last registered owner on file. A real case that made national news in late 2025 shows exactly how this plays out.
A man in British Columbia sold his SUV, and the buyer never registered it. Months later, he was billed for towing and storage charges tied to a vehicle he no longer owned, because his name was still the one on record. Alberta’s registration system works the same basic way as most Canadian provinces here: the seller doesn’t get removed from the file by handing over keys, only by someone actually completing the transfer.
Warning Signs You're Selling to a Curbsider
AMVIC publishes warning signs for buyers trying to spot a curber. Flipped around, most of the same patterns apply just as clearly to someone posing as a private buyer.
- Vague or evasive answers about identity. A genuine private buyer has no reason to hesitate over basic questions about who they are or why they’re buying. Hesitation, inconsistent names, or a refusal to show ID before money changes hands is worth noticing.
- Requests to skip or delay the registry step. Anyone framing the registration transfer as something to “sort out later,” or asking you to leave the buyer’s information blank on the bill of sale, is asking for exactly the gap curbsiders rely on.
- Interest in multiple vehicles, or a pattern that feels like a business. A buyer who mentions flipping cars regularly, or who you later notice has bought several vehicles from different sellers around the same time, isn’t behaving like an ordinary one-time private buyer.
- Wanting to meet somewhere other than your home, with cash only, and quickly. None of these alone is proof of anything, but together with the other signs, they point toward someone trying to minimize any trace of the transaction.
- Pressure to complete the sale faster than feels comfortable. A legitimate buyer can wait while you fill out paperwork properly. Someone pushing you to skip steps has a reason for wanting those steps skipped.
How to Protect Yourself When Selling a Car Privately in Alberta
A few concrete habits close most of the gap a curbsider is counting on, regardless of how the buyer presents themselves.
Fill out a complete bill of sale with the buyer’s full legal name, address, and signature, and keep your own copy indefinitely, since this document is what actually transfers ownership. Remove your licence plates before the buyer leaves, since plates stay with you in Alberta rather than transferring with the vehicle, and provide the buyer with the completed bill of sale and any other documents relevant to the transaction. Cancel or transfer your insurance on that vehicle once the sale is complete, since that cancellation date becomes another piece of evidence showing when your connection to the vehicle actually ended.
If you’re at all unsure whether the buyer followed through on registering it, you can order a Vehicle Information Report using the VIN weeks or months later to check the vehicle’s current registration status, which is a reasonable step if something about the sale felt off at the time.
What to Do If You Already Sold to a Curbsider
If a sale already happened and something about it doesn’t sit right, a few steps limit the damage from here.
Pull together everything you still have: the bill of sale, any messages with the buyer, and a note of the date and circumstances of the sale. Check the vehicle’s current registration status through a Vehicle Information Report if you’re able to, since that shows whether it’s still showing under your name in the registration record.
If it is, and a reasonable amount of time has passed, contacting Alberta’s registry system for guidance and reporting the suspected curber to AMVIC are both worth doing, since AMVIC actively investigates these operators and relies on exactly this kind of report to build cases against them.

Conclusion
A private car sale in Alberta transfers ownership the moment a proper bill of sale is signed, but that’s not the whole story from a registration standpoint. Until the buyer actually registers the vehicle, it can still appear under your name in Alberta’s records, and a curbsider’s whole strategy depends on that gap staying open as long as possible, sometimes with your direct help if you don’t realize what leaving paperwork incomplete actually costs you.
None of the protections here are complicated. A complete bill of sale, plates removed, insurance cancelled, and a healthy suspicion of anyone asking you to skip a step are usually enough to close the gap a curbsider needs. If something already happened and you’re not sure where things stand, checking the vehicle’s current registration status is a concrete way to find out rather than wonder.
