How Truck Evidence Disappears in Ontario: The 6-Month Rule and the Preservation Letter That Stops It

After a serious truck crash, you may spend the next few weeks managing pain, medical appointments, insurance calls and vehicle repairs. At the same time, important records may be quietly moving towards deletion.

Electronic logs, GPS data, dispatch messages and camera footage can reveal fatigue, speeding, poor maintenance or pressure to meet a delivery deadline. Yet some regulated records only need to be kept for a minimum period, while other digital files can disappear much sooner.

That’s why truck accident evidence Ontario claims depend on can become a race against time. Knowing what the six-month rule covers and sending the right preservation notice early can help protect the facts before routine deletion removes them.

The Evidence Clock Starts on Crash Day

A truck creates a large paper and digital trail, but you usually control none of it. The driver, carrier, maintenance company, shipper and technology providers may each hold different records. Unless they are identified quickly, you may never know they existed.

What Is Ontario’s Six-Month Rule?

The “six-month rule” does not cover all evidence from a truck collision. Ontario’s Ministry of Transportation says commercial driver hours-of-service requirements are contained in Ontario Regulation 555/06 under the Highway Traffic Act. Drivers and operators must record driving, on-duty and off-duty time.

Federal rules also require motor carriers to keep records of duty status and supporting documents for at least six months after receiving them. Those records may reveal inadequate rest, excessive hours or inaccurate duty changes. However, six months is the minimum for certain regulated records, not a guarantee that every useful file will last that long.

Which Records Could Explain What Happened?

Useful truck accident evidence Ontario claims may include:

• Electronic logging device records
• GPS, speed and route data
• Dashcam or in-cab footage
• Dispatch schedules and messages
• Driver training and safety files
• Inspection and maintenance records
• Cargo and loading documents
• Phone records
• Truck system data

Several records viewed together may reveal fatigue, distraction, speeding, unsafe loading or a mechanical problem.

Some Evidence Can Disappear Much Earlier

Waiting six months can be far too late. Camera systems may overwrite footage within days or weeks. Telematics providers may keep data briefly. A damaged truck may be repaired, removing physical clues. Nearby security video may also be deleted.

Routine business activity can erase evidence. Phones are replaced, apps clear messages, vehicles are sold and paper files follow retention policies. The six-month rule is not a safe waiting period. Strong evidence may disappear much earlier.

How a Preservation Letter Helps

A preservation letter gives written notice that a collision may lead to a legal claim and that relevant evidence must not be deleted, changed or overwritten.

An evidence preservation letter Ontario truck accident lawyers prepare should identify the collision, vehicles, people and records involved. It can ask recipients to suspend deletion and protect backups.

The letter does not prove fault. It creates a record that evidence holders were told to preserve relevant material. Canadian electronic-discovery principles distinguish evidence-preservation obligations from ordinary regulatory record-keeping requirements.

What Should the Letter Protect?

A strong letter should be specific; it should not simply say “save everything.” It may cover driver logs, ELD data, GPS records, video, dispatch messages, training files, maintenance records, cargo documents and backups.

It may also request preservation of the truck, trailer and damaged parts. The list should match how the crash happened.

Who Should Receive the Notice?

The trucking company may be a recipient, but it might not control every record. Notices may also need to reach the driver, owners, maintenance contractor, shipper, insurer or technology provider.

An evidence preservation letter Ontario truck accident claimants rely on works best when it reaches each organization holding relevant information.

What If Evidence Is Destroyed?

Missing records can raise serious questions. A court might look at things like whether the process was supposed to happen, if the evidence actually mattered, when notice was received and whether the loss was accidental or deliberate, you know.

Steps to Take After a Truck Crash

• Get medical attention and report the collision.
• Photograph the road, vehicles, cargo and damage.
• Save videos, messages and insurance documents.
• Collect witness details quickly.
• Avoid a quick settlement before understanding the evidence.

A Toronto truck accident lawyer can identify evidence holders, send targeted notices and help protect records you cannot access yourself.
