What Records Should Be Requested After a Truck Accident in Ontario?

After serious truck accidents in Ontario, many of the key records are held by companies, not by the drivers standing at the scene.
Those records commonly include driver logs, electronic logging data, dispatch messages, GPS records, maintenance files, inspection reports, ECM or black box data, dash camera footage, loading records, bills of lading, scale tickets, insurance certificates and company safety documents.
These are often evidence that helps show how the crash happened, which companies were involved, and which insurance policies should respond. In many truck accident claims, the most important documents are held by the trucking company, vehicle owner, trailer owner, maintenance contractor, warehouse, shipper, broker, loading company, insurer or another business connected to the commercial operation.
We more broadly explain common issues in trucking accidents such as, liability, insurance and serious injuries, on our Ontario truck accident lawyers page.
Why the Police Report Is Not Enough
Police reports are useful, but rarely tell the whole story in a serious truck accident claim. The report will usually identify the drivers, vehicles, location, weather, road conditions, charges, witness names and the officer’s initial observations. That information helps establish the basic framework of the collision.
However it will not always tell you who owned the trailer, who loaded the cargo, who scheduled the route, whether the driver had enough rest, whether the truck had brake problems, whether a repair was done shortly before the collision, or whether electronic data showed hard braking, speeding or sudden deceleration.
It also usually does not identify all available insurance.
That is the investigation usually goes beyond the police report. In serious cases, a preservation letter should be sent early so trucking, electronic, maintenance and loading records are not lost before the claim is investigated.
Driver Qualification and Employment Records
The driver’s file is often one of the first places to look. A commercial driver’s records can show whether the driver was properly licensed, trained and supervised. They can also show whether the driver had prior safety problems, discipline, complaints, collisions or warnings before the crash.
The relevant file can include licence information, hiring documents, training records, supervision notes, disciplinary records, employment or contractor agreements and prior incident history available through the company.
These records are requested because some collisions trace back to a larger safety problem inside the company. If the driver had a history of unsafe driving, poor training, ignored complaints or weak supervision, the claim looks different than a simple one-driver mistake.

Hours-of-Service Records and Driver Logs
Fatigue is one of the most important record issues in serious truck accident cases. A truck driver can spend long hours driving, waiting at loading docks, dealing with delays, driving overnight or trying to meet delivery deadlines. Logs and electronic records can show how long the driver had been on duty, where the driver had been, how much rest the driver had, and whether the trip complied with applicable hours-of-service rules.
The records can include electronic logging device data, duty-status records, paper logs, trip sheets, fuel receipts, GPS records, toll records, delivery documents and communications between the driver and the motor carrier.
Dispatch Messages and Trip Records
Dispatch records assist in showing how the trip was planned and managed. That matters since drivers are not always the only person making decisions. A dispatcher, fleet manager, broker, shipper or logistics company can be involved in route planning, delivery timing, pickup windows, delay management and instructions to the driver.
These documents are especially important where the trucking company later claims the driver alone made the unsafe decision. If the dispatch records show pressure to keep moving despite fatigue, weather, delays or mechanical concerns, the case can look very different.
GPS, Telematics and Fleet Tracking Records
Many commercial vehicles are tracked through GPS or fleet-management systems.
Those records can show where the truck travelled, how fast it was moving, where it stopped, how long it waited, when it resumed driving and whether the trip matched the logs or dispatch records.
Depending on the system, telematics can also show harsh braking, rapid acceleration, sharp turning, speed patterns or other driving behaviour before the crash. GPS and telematics records can help reconstruct the truck’s movement before the collision.
The problem is how long the data is kept. Some systems do not keep data forever. If no one asks for the records early, they can be overwritten or lost through ordinary business practices.
ECM, Black Box and Event Data
Commercial trucks often contain electronic data from the engine control module or other vehicle systems. People often call this ECM data or black box data, although the exact information depends on the truck and the system involved.
In the right case, this data can show speed, braking, throttle position, engine activity, sudden deceleration or other information from the seconds before the crash. That can be extremely important where the parties disagree about speed, stopping distance, braking, lane movement or loss of control.
The issue is control. The data can be held by the trucking company, vehicle owner, fleet manager or a third-party data provider. It can also be lost during repairs, overwritten, or never downloaded unless someone acts quickly.
Dash Camera and Video Footage
Video often disappears quickly. A truck can have dash cameras, driver-facing camera, side camera, rear camera or fleet camera system. Nearby businesses, homes, municipalities, construction sites, gas stations, loading docks or other vehicles can also have useful footage.
However, in our experience, many video systems overwrite footage after a short period. Some businesses keep footage for days, not months. Fleet camera footage can be controlled by the trucking company or uploaded through a third-party platform that the injured person has never heard of.
A preservation request should be sent quickly where video is likely to exist.
Inspection Reports and Maintenance Records
Maintenance records become important if a truck could not stop in time, lost control, suffered a tire failure, had brake problems, jackknifed, rolled over or had an obvious mechanical issue.
The records can include pre-trip inspections, post-trip inspections, annual inspection documents, repair invoices, maintenance logs, defect reports, brake records, tire records, steering records, lighting records, coupling records, trailer inspection documents and work orders from third-party repair shops.
A repair from two years earlier is usually less important than an inspection or repair shortly before the crash. A repeated defect is different from a one-time issue. A defect noted before the collision but not fixed can be very important.
The records can also show whether maintenance was handled internally or by an outside contractor. If an outside repair shop missed a defect or performed a repair improperly, that contractor’s records and insurance should be reviewed.
Truck and Trailer Ownership Records
The tractor and trailer are not always owned by the same company. That matters for both liability and insurance. One company can own the tractor. Another can own the trailer. A different company can employ or contract with the driver. Another business can arrange the shipment. A warehouse or manufacturer can load the cargo.
Important records can potentially include ownership documents, registration records, lease agreements, carrier information, trailer records, insurance certificates and contracts between the companies involved.
In serious injury cases, these documents help identify who had control over the truck, who had control over the trailer, and which insurance policies should respond.
Cargo and Loading Records
Cargo records are important where the crash involved a rollover, jackknife, fallen cargo, shifting cargo, sudden loss of control, poor braking or trailer instability.
Trucks can sometimes be loaded by a warehouse, manufacturer, shipper, distributor, loading contractor or other commercial party. The cargo can be overweight, poorly packaged, unevenly distributed or improperly secured.
Relevant documents can include bills of lading, scale tickets, loading records, dock records, warehouse documents, securement records, shipment instructions, weight records, photographs, cargo manifests and communications about the load.
These records help answer basic questions. What was being carried? Who loaded it? How heavy was it? How was it secured? Did anyone identify a problem before the truck entered the road? If the cargo or loading process contributed to the crash, the records can also identify another company and another insurance policy.
Warehouse, Shipper and Broker Records
The trucking company is not always the only business involved in the shipment.
A shipper can prepare the load while a warehouse loads the trailer. A manufacturer can package the cargo. A broker or logistics company can arrange the carrier. Dispatchers usually manage timing and communications.
Records from those companies can show what happened before the truck reached the road. This can include broker-carrier agreements, shipper contracts, warehouse records, dock records, scheduling documents, emails, shipment instructions, carrier selection documents and insurance certificates.
Most cases do not involve every company in the shipment chain. But where the records show that another business helped create the risk, that business’s documents become important.
Insurance Certificates and Policy Information
Insurance records should be requested early in serious truck accident claims.
A commercial truck accident can involve more than one policy. There can be insurance connected to the driver, motor carrier, vehicle owner, trailer owner, warehouse, shipper, broker, maintenance contractor or another commercial party.
There can also be umbrella or excess insurance above the primary policy.
Insurance certificates, policy information, lease documents and commercial contracts help identify which companies and insurers are involved. In catastrophic injury and fatal accident cases, this can be critical because the losses can exceed the first policy identified.
Company Safety Policies and Training Materials
Company policies can show what should have happened before the crash.
A trucking company can have policies for driver training, fatigue management, vehicle inspections, maintenance, cargo securement, dispatch, weather conditions, cell phone use, incident reporting and post-collision procedures.
The existence of a policy is not enough. The harder question is whether the company actually followed it. Training records, safety meeting records, audit records and internal incident reports can show whether the company had a real safety system or simply kept paperwork.
Post-Collision Records
The records created after the collision can also become important in certain cases. A company can prepare an internal incident report. The truck can be inspected. Repairs can be performed. The driver can give a statement. The company can notify an insurer. Photos can be taken. Electronic data can be downloaded. The vehicle can be moved, repaired or returned to service.
Those records can show what the company knew immediately after the crash and what steps it took with the evidence.
We have seen that post-collision records can sometimes include internal reports, photographs, repair invoices, inspection records, insurer communications, driver statements, tow records and records of electronic data downloads.
Why Records Should Be Requested Early
Some truck accident records are time-sensitive. Dash camera footage can be overwritten. ECM or telematics data can be lost. A truck can be repaired. Inspection documents can be replaced by later records. Dispatch messages can be deleted. Warehouse video can disappear. A third-party contractor can have a short retention period. Preservation letters help reduce that risk.
A preservation letter should be directed to the people and companies that hold relevant records. In a serious truck accident, that can include the trucking company, driver, vehicle owner, trailer owner, insurer, maintenance provider, warehouse, shipper, broker, loading company, fleet-management provider or another business connected to the collision.

What If a Company Says the Records Are Gone?
Sometimes a company will say that the records no longer exist. It then becomes important to understand when the records were lost, who controlled them, what preservation requests were made, whether the company had a retention policy, whether the records were overwritten automatically, and whether copies exist somewhere else.
Dispatch messages can be stored in more than one system. GPS data can be held by a fleet-management provider. Video can be uploaded to a third-party platform. Maintenance records can be held by a repair shop. Loading records can be held by a warehouse or shipper.
A serious truck accident investigation will not assume that a missing record is truly unavailable until the possible sources have been checked.
When to Contact a Lawyer About Truck Accident Records
You should obtain legal advice early if the collision involved a transport truck, tractor-trailer, dump truck, delivery truck, cube van or other commercial vehicle and the injuries are serious.
Early advice is especially important if the trucking company or insurer has contacted you, the vehicle has been repaired or moved, dashcam footage exists, the crash involved a rollover or fallen cargo, the truck was from outside Ontario, the driver was working, or there is uncertainty about which companies were involved.

FAQ
What records should be requested after a truck accident in Ontario?
Important records can include driver logs, electronic logging device data, dispatch messages, GPS records, ECM data, dash camera footage, inspection reports, maintenance files, repair invoices, loading records, bills of lading, scale tickets, insurance certificates and company safety records.
Is the police report enough after a truck accident?
Usually not. A police report can identify the drivers, vehicles and basic collision details, but it usually does not show who owned the trailer, who loaded the cargo, whether the driver was properly scheduled, whether maintenance was overdue, or which insurance policies apply.
Why are driver logs important after a truck accident?
Driver logs and electronic logging records can show how long the driver had been on duty, whether the driver had enough rest, where the truck travelled and whether the trip complied with applicable hours-of-service rules.
What is ECM or black box data in a truck accident claim?
ECM or black box data can show information about the truck’s speed, braking, throttle position, engine activity or sudden deceleration before the crash. The exact information depends on the truck and the system involved.
Can loading records matter after a truck accident?
Yes. Loading records can matter where the crash involved shifting cargo, fallen cargo, a rollover, jackknife, poor braking or trailer instability. These records can show who loaded the truck, what was being carried, how heavy the load was and how it was secured.
Can warehouse or shipper records be requested after a truck accident?
Yes, where the loading, packaging, shipment or securement of the cargo is relevant. A warehouse, manufacturer, shipper or loading company can have records showing how the cargo was prepared, loaded, weighed, packaged or secured before the truck entered the road.
How long are truck accident records kept?
There is no single retention period for every record. Some video footage and electronic data can be overwritten quickly. Maintenance, inspection, dispatch, loading and insurance records can be kept longer depending on the company, system and legal requirements. In a serious truck accident claim, preservation requests should be sent early rather than assuming the records will still exist later.
Why should truck accident records be preserved early?
Some records are overwritten, deleted, repaired over or lost through ordinary business practices. Dash camera footage, ECM data, telematics records, dispatch messages, warehouse video and maintenance records should be considered early in a serious truck accident claim.
What if a trucking company says the records are gone?
The issue should be examined carefully. Records can exist with another company, insurer, repair shop, fleet-management provider, warehouse, broker or third-party system. The timing and reason for the missing records can also become important.
Can insurance records be requested after a truck accident?
Yes. Serious truck accident claims often require insurance certificates, policy information, lease documents and commercial contracts to identify available insurance connected to the driver, trucking company, vehicle owner, trailer owner, shipper, warehouse or another party.
Should I contact a lawyer before requesting truck accident records?
Yes, especially after a serious injury has occurred. Experienced truck accident lawyers will send preservation letters, identify the companies that hold relevant records and request documents before important evidence is lost or overwritten.
