What Are Vehicle History Reports?
A complete guide to vehicle history reports in Canada — what they show, how Carfax Canada and CARPROOF work, how dealers and consumers use them, and the limitations to understand before relying on them.
Key takeaways
- Vehicle history reports show registered events — accidents, lien data, branding, ownership, mileage records
- Carfax Canada (formerly CARPROOF) is the dominant Canadian provider
- Dealers run reports on every used vehicle they acquire and typically share them with buyers
- Reports show only reported data — undocumented incidents and private repairs may not appear
Quick Answer
A vehicle history report is a document that compiles a vehicle's recorded history from multiple data sources — insurance claims, lien registries, motor vehicle departments, police reports, and dealership/auction records. The report typically includes accident history, branded title information, odometer readings, lien status, registration history, and any recall information. In Canada, the dominant provider is Carfax Canada (which acquired and rebranded CARPROOF around 2020). Dealers run a vehicle history report on every used car they acquire as part of acquisition due diligence, and most dealerships share the report with buyers as a trust signal during the sale.
What is a vehicle history report?
A vehicle history report is a structured summary of everything that's been formally recorded about a specific vehicle, identified by its VIN (Vehicle Identification Number). The report compiles data from multiple sources: provincial motor vehicle authorities, insurance companies, lien registries, police accident reports, manufacturer recall databases, and dealer/auction transaction records. The result is a single document that gives a much more complete picture than what a buyer can see from inspecting the vehicle alone.
For consumers, vehicle history reports are a major trust signal in the used-car buying process. A clean report says "this vehicle has nothing to hide." A report flagging accident history, branded title, or lien complications gives the buyer information they need to make an informed decision. Most reputable dealerships in Canada provide a Carfax Canada report with every used vehicle as a standard part of the sales process.
For dealers, vehicle history reports are operational due diligence. Every used vehicle acquired through trade-in, auction, or street purchase gets a report run before the dealership commits to the purchase. The report flags issues that affect both legal compliance (mandatory disclosure of accident history, branded titles) and reconditioning estimates (vehicles with significant prior damage often need more work than they appear to).
The Canadian vehicle history report market
The Canadian vehicle history report market is dominated by one provider with a clear history.
Carfax Canada (formerly CARPROOF)
CARPROOF was the dominant Canadian vehicle history report provider for many years, founded specifically to serve the Canadian market with Canadian data sources. In 2015, CARPROOF was acquired by IHS Markit, and around 2020 the company was acquired by Carfax (the dominant US-based vehicle history report provider). Following the acquisition, CARPROOF was rebranded as Carfax Canada. The product is the same Canadian-specific report — built on Canadian data sources, including provincial motor vehicle records, ICBC and other provincial insurance data, and Canadian police records — but now under the Carfax brand.
Carfax Canada is the standard vehicle history report provider for Canadian dealerships and is the report most consumers expect to see when shopping for a used vehicle in Canada.
Other providers
AutoCheck, owned by Experian, also offers vehicle history reports in Canada but has significantly smaller market share than Carfax Canada. Some dealerships and online marketplaces use AutoCheck either alongside or instead of Carfax reports.
For most Canadian transactions, "vehicle history report" effectively means "Carfax Canada report."
What's in a vehicle history report?
The specific contents vary by provider and by what data is available for a particular vehicle, but most reports include some combination of:
- Title and branding information — whether the vehicle has been declared salvage, rebuilt, non-repairable, or has any other title brand
- Registration history — how many owners the vehicle has had, what provinces or states it has been registered in, and the dates of each registration
- Accident and damage history — reported collisions, insurance claims, and damage estimates where available
- Odometer readings — recorded mileage at various points (registration, service, sale) used to detect odometer rollback or inconsistencies
- Lien information — registered financial liens against the vehicle that need to be discharged before sale
- Service records — where dealerships and service providers have reported maintenance history
- Recall information — manufacturer recalls applicable to the vehicle, including whether they've been completed
- Auction history — if the vehicle has been through wholesale auction (Manheim, ADESA), with the date and condition declared at auction
- Theft records — whether the vehicle has been reported stolen
- Use history — flags for prior use as a rental, taxi, fleet, or police vehicle when this can be determined
The level of detail depends on what data is available. A vehicle that has spent its entire life in a single Canadian province with a clean record will have a simple, short report. A vehicle that has crossed borders, had multiple owners, or been involved in incidents will have a much longer one.
How dealerships use vehicle history reports
Vehicle history reports are integrated into several points of the dealership operational workflow.
At acquisition
Every used vehicle acquired by a dealership — through trade-in, auction, lease return, or street purchase — gets a vehicle history report run as part of due diligence. This happens before the dealership commits to the purchase. The report flags issues that affect the value (accident history, branded title, recurring damage), the reconditioning estimate (vehicles with significant prior damage usually need more work), and legal compliance (anything that needs to be disclosed to a future buyer).
At trade-in
When a customer brings a vehicle in for trade-in valuation, the appraiser runs a Carfax report as part of the assessment. The report can change the offer significantly — a vehicle with undisclosed accident history might get a much lower offer than the customer expected, and that conversation needs to happen at the time of appraisal, not after.
At listing
Many dealerships display the Carfax report (or a summary) on their used vehicle listings, both on the dealership website and on inventory feed platforms like AutoTrader.ca. Vehicles with clean reports are explicitly marketed as "Carfax verified" or similar.
At sale
The Carfax report is typically printed (or shared digitally) with the customer as part of the documentation package. This is both a trust signal and a compliance protection for the dealership — if the report shows certain issues and the customer signs the sale knowing about them, the dealership has a documented disclosure record.
For compliance
The mandatory disclosure rules under provincial dealer regulations require dealers to disclose accident history, branded titles, and other facts about used vehicles. Vehicle history reports are the primary source of this information for the dealership. A dealer that runs a Carfax on every acquired vehicle has a much stronger compliance posture than one that doesn't.
Limitations of vehicle history reports
Vehicle history reports are valuable but they have known limitations. Both dealers and consumers should understand what reports can and can't tell you.
Only reported data shows up
Vehicle history reports compile data from sources that report to them. Anything that wasn't reported won't appear. A minor accident repaired privately by the owner with no insurance claim and no police report won't be in the database. The vehicle could have had significant damage that's invisible to the report.
Cross-border gaps
Vehicles that have crossed between Canadian provinces or between Canada and the US sometimes have gaps in their records as data crosses jurisdictional boundaries. Carfax Canada handles this better than older systems but it's not perfect.
Reporting lag
Some events take weeks or months to appear in reports after they happen. A recent accident might not yet be in the database when the vehicle is being sold.
Interpretation matters
A reported accident isn't always a problem — it could have been a minor fender-bender that was fully repaired with no lasting impact on the vehicle. A consumer reading the report might over-react to a flag that's actually fine, or under-react to one that's actually significant. The report needs to be interpreted alongside a physical inspection.
Not a substitute for inspection
The most important limitation: a vehicle history report is one data point among several. It doesn't replace a physical inspection by a qualified mechanic. Dealerships always combine the report with a multi-point inspection during reconditioning, and consumers should always insist on a pre-purchase inspection (PPI) for any used vehicle even if the Carfax is clean.
Frequently asked questions
What is a vehicle history report?
A vehicle history report is a structured document compiling everything formally recorded about a specific vehicle (identified by VIN) from sources like motor vehicle authorities, insurance companies, lien registries, and dealer/auction records. It typically shows accident history, title brands, ownership history, mileage records, and lien status.
What's the difference between Carfax Canada and CARPROOF?
CARPROOF was the dominant Canadian vehicle history report provider for years before being acquired by Carfax (the US provider) and rebranded as Carfax Canada around 2020. The product is the same Canadian-specific report built on Canadian data sources, just under a new name.
How much does a Carfax Canada report cost?
For consumers, individual report pricing varies and changes over time — check Carfax Canada's current consumer pricing. For dealers, Carfax operates on dealership subscription pricing that allows running unlimited reports on owned inventory. Most dealerships include the cost of reports in their general operational overhead and provide reports to customers free of charge as part of the sale.
Should I trust a clean Carfax report?
A clean report is a positive signal but not a guarantee. Vehicle history reports only show reported data — undocumented incidents (private repairs, minor unreported accidents, certain types of damage) may not appear. Always combine a vehicle history report with a physical inspection by a qualified mechanic before buying any used vehicle.
Do dealerships have to provide a vehicle history report?
There's no universal requirement that dealerships provide a printed vehicle history report, but most reputable Canadian dealerships do as a standard practice. Provincial dealer regulators require disclosure of certain facts about used vehicles (accident history, branded titles, etc.), and the vehicle history report is the primary source of this information.
Are vehicle history reports mandatory in Canada?
Vehicle history reports themselves aren't mandatory under Canadian law, but the information they contain is — provincial regulators like OMVIC and AMVIC require dealers to disclose accident history, branded titles, and prior use. The vehicle history report is how dealers obtain this information for their disclosure obligations.
The bottom line
Vehicle history reports are an essential tool in the used-car ecosystem — for dealers, they're operational due diligence and compliance documentation; for consumers, they're a trust signal and an information source for an informed buying decision. In Canada, Carfax Canada (formerly CARPROOF) is effectively the standard, and any reputable dealership runs a report on every used vehicle they acquire.
The most important thing to understand about vehicle history reports is what they don't show. Undocumented events, private repairs, and minor unreported incidents won't appear. A clean report is a positive signal but never a substitute for a physical inspection by a qualified mechanic before buying any used vehicle.
