Quick Answer
Yes. Dashcam footage can be used as evidence in an Ontario car accident claim if it is relevant and can be authenticated. Preserve the complete native recording and original memory card. Do not edit, delete or post the footage before it has been reviewed, because the recording may contain evidence that helps or hurts your case.
Ontario car accident lawyers frequently find that dashcam footage can clarify traffic-signal colour, lane position, visibility, braking, the sequence of impacts and what was said immediately after a collision. In some cases, it provides the clearest available evidence of how the crash occurred.
Its value depends on more than the few seconds showing the impact. The complete recording should be preserved in its original format, together with the memory card and available information about how the file was created, copied and stored.
A recording that supports a claim against another driver can also reveal speed, distraction, delayed braking or other evidence that may be considered unfavourable to the person who owns the camera.
What Can Dashcam Footage Prove After a Car Accident?
Police reports ordinarily records information gathered after a collision. Dashcam footage can show part of the event itself.
Depending on the camera’s position and image quality, the recording may help establish:
which vehicle entered an intersection first;
whether a traffic signal was red, amber or green;
where each vehicle was positioned within its lane;
whether brake lights were activated;
how much time a driver had to react;
the order of impacts in a multi-vehicle collision;
road, lighting and weather conditions;
whether another vehicle stopped after the crash; and
statements made inside or near the recording vehicle.
Those details can become especially important when the drivers provide conflicting accounts, which is often the case in motor vehicle collisions.
Dashcam evidence is especially valuable after hit and run collisions. It may capture the fleeing vehicle, part of a licence plate, its direction of travel or witnesses who stopped nearby. Even if the plate is not legible, the recording could help establish that another vehicle was involved and support efforts to identify it.
Our page for Ontario hit-and-run injury lawyers explains the insurance and evidentiary issues that arise when the responsible driver leaves the scene or cannot be identified.
Video does not replace the legal analysis. Our guide to how fault is determined in Ontario car accidents explains why an insurer’s application of the Fault Determination Rules differs from the negligence analysis used in a personal injury lawsuit.
Does Dashcam Footage Automatically Prove Who Was at Fault?
Not always. A recording can appear decisive when it is first viewed, but every camera records from one position and through a lens with a limited field of view.
Forward-facing cameras might not be able to capture a vehicle approaching from the side, a pedestrian initially hidden by another vehicle or events occurring behind the recording car. It ordinarily cannot show where the driver was looking, whether mirrors were checked or what was visible outside the camera’s frame.
The camera’s internal clock could also be wrong. Wide-angle lenses can impact the percieved distance between objects. A displayed speed reading may depend on GPS information or camera settings that require separate verification.
How Should Dashcam Footage Be Preserved After an Accident?
Many dashcams use a form of loop recording. This means that once the memory card is full, the system writes over older footage unless a file has been locked or saved separately.
The minutes surrounding a collision can therefore disappear even though nobody meant to delete them.
After immediate medical and safety concerns have been addressed, the camera should be prevented from overwriting the recording. The original memory card should be removed or secured, and the native file should be copied to more than one storage location
.
The safest approach is generally to:
preserve the original memory card;
save the native video file rather than only filming the screen with a phone;
retain the complete period before and after the impact;
create at least two backup copies;
avoid changing or overwriting the original file; and
record basic information about the camera and how the copies were created.
It is important to preserve more than the moment of impact. The recording before the collision could show traffic flow, lane position, speed changes, weather conditions or the conduct of another driver. The period afterward could record statements, additional impacts, a vehicle leaving the scene or the arrival of witnesses.
Why Should the Original File and Memory Card Be Kept?
Recordings that are sent through messaging applications or uploaded to social media may be compressed, converted or stripped of associated file information.
The native file may contain information about when it was created, its duration, the device that produced it and whether GPS data was recorded. The memory card can help connect the file to the camera that made the recording.
The original does not need to be used every time someone watches the footage. A working copy can be created for review and production while the source file and memory card remain unchanged.
A copied or converted video is not necessarily inadmissible. The concern is whether the recording can be reliably connected to the collision and whether there is a sufficient basis to conclude that it accurately depicts the event. Preserving the source evidence makes those questions easier to answer.
Is Dashcam Footage Admissible in an Ontario Court?
Dashcam footage can certainly be admitted in an Ontario lawsuit, but the existence of a video file does not establish by itself that the recording is authentic, complete or reliable.
Section 34.1(4) of Ontario’s Evidence Act provides that the person seeking to introduce an electronic record has the burden of producing evidence capable of supporting a finding that the record is what the person claims it to be.
This means that if the best-evidence rule applies, section 34.1(5) provides that it can be satisfied by proof of the integrity of the electronic record. Section 34.1(5.1) permits integrity to be established through evidence concerning the electronic-record system in which the data was recorded or stored.
The Supreme Court of Canada considered video evidence in R. v. Nikolovski, 1996 CanLII 158 (SCC). The Court recognized that a properly authenticated video can operate as real evidence of the event recorded by the camera. It can be assessed directly rather than treated merely as a visual aid to a witness’s testimony.
A useful contrast appears in R. v. Andalib-Goortani, 2014 ONSC 4690. That case involved an image obtained from the internet. Its original source was uncertain, identifying metadata had been removed and the court was not satisfied that the image had been reliably authenticated. The image was excluded.
Both decisions arose in criminal proceedings, but the authentication concerns are also relevant when electronic video is offered in a civil lawsuit. Depending on the circumstances, the supporting evidence could address:
who owned or operated the camera;
where the camera was positioned;
whether the recording depicts the collision location;
whether its clock and GPS settings were accurate;
whether the complete recording has been retained;
whether the file was edited or converted; and
how it was copied and stored.
Witnesses who observed the collision might be able to confirm that the footage fairly depicts what occurred. Other cases could require evidence about the camera, memory card, file history or recording system.
An incorrect date or time does not necessarily invalidate everything captured by the camera. It does mean that the timestamp should not be accepted without examination and that other evidence may be needed to connect the recording to the collision.
Can Edited Dashcam Footage Be Used in Court?
An edited recording is not necessarily excluded automatically, but editing can create questions about completeness, context and reliability.
A short excerpt may still be useful where the complete source recording has also been preserved and the editing process can be explained. The difficulty is greater where the original file has disappeared and only a clipped, slowed, captioned or converted version remains.
Editing can remove evidence that changes the apparent meaning of the selected segment. It may also affect metadata, playback quality and the ability to determine whether frames were removed.
Does an Incorrect Timestamp Make Dashcam Footage Inadmissible?
Not necessarily. The date and time displayed by a dashcam depend on the device being configured correctly. A driver may never have adjusted the clock after purchasing the camera, changing time zones or replacing the battery.
Other evidence can sometimes establish when and where the recording was created, including the collision report, visible landmarks, weather, vehicle damage, witness testimony or the sequence of files on the memory card.
Must Dashcam Footage Be Disclosed If It Hurts Your Case?
Yes. Relevant footage cannot be withheld from other parties simply because it was recorded by your own camera or because part of it is unfavourable.
Rule 30.01 of Ontario’s Rules of Civil Procedure defines a document to include videotape, film, photographs and data or information in electronic form. Under
Rule 30.02, every relevant document that is or has been within a party’s possession, control or power must be disclosed, whether or not it helps that party’s case.
Dashcam footage could reveal excessive speed, a late entry into an intersection, close following distance, delayed braking, distraction or an unsafe lane change. Audio could record statements that conflict with the account later given to the police or insurer.
Providing an existing recording to a lawyer does not transform the underlying video into privileged evidence. The recording existed independently of the solicitor-client relationship and remains subject to the ordinary rules governing relevant documents. Communications between the lawyer and client about the recording can raise separate privilege issues.
The disclosure obligation extends beyond files that remain in the party’s possession. Rule 30.03 requires an affidavit of documents to identify relevant documents that were formerly possessed or controlled and to state when and how possession was lost.
That provision becomes significant where a party says the video was overwritten, the memory card was lost or the file was deleted before the affidavit of documents was prepared.
Rule 30.08 gives the court authority to address a failure to disclose or produce a document. A favourable document that was not properly disclosed generally cannot be used at trial without leave. Where the undisclosed document is unfavourable to the party who failed to disclose it, the court can make an order that is just in the circumstances.
Will an Ontario Insurance Company Consider Dashcam Footage?
Ontario insurance companies will consider any dashcam footage when investigating how a collision occurred. The recording could affect the insurer’s assessment of fault, vehicle damage or an injury claim.
The complete recording should be secured before a copy is provided. An insurer may also ask for the file in a particular format or request footage covering a longer period than the collision itself. The scope and relevance of the request should be considered before production, but obtaining legal advice does not eliminate a legitimate disclosure obligation.
What If the Other Driver Refuses to Provide Dashcam Footage?
A camera may be visible in the other vehicle even though the recording is not produced voluntarily. The vehicle owner or insurer can be asked to retain the complete recording, original storage media, associated GPS information and details about the camera system.
A preservation request does not compel the recipient to hand over the video. However its immediate purpose is to identify evidence that should not be lost through routine overwriting while production is pursued.
Once the litigation begins, relevant footage within another party’s possession, control or power falls within the documentary-discovery rules. A party cannot avoid disclosure merely by refusing an informal request.
Footage held by a witness, nearby business, homeowner or another person who is not a party to the lawsuit requires a different procedure. Under Rule 30.10 of the Rules of Civil Procedure, the court can order a non-party to produce a non-privileged document where it is relevant to a material issue and it would be unfair to require the requesting party to proceed to trial without discovering it.
What If Dashcam Footage Is Deleted or Overwritten?
There is an important distinction between routine overwriting before anyone recognized that litigation was likely and the intentional destruction of evidence that a person knew should be preserved.
Ontario law refers to the intentional destruction or suppression of relevant evidence as spoliation.
In Spasic Estate v. Imperial Tobacco Ltd., 2000 CanLII 17170 (ON CA), the Ontario Court of Appeal discussed the traditional spoliation inference: an inference or presumption that evidence deliberately destroyed by a litigant would have been unfavourable to that person.
The decision arose from a motion to strike. The Court did not definitively establish the elements of an independent tort of spoliation, but it declined to foreclose the possibility that such a claim could be recognized on an appropriate record.
A missing dashcam file does not automatically result in a sanction or prove that the other driver was at fault. The surrounding circumstances remain central: when the recording disappeared, whether litigation was underway or reasonably anticipated, whether the loss was deliberate and whether another copy exists.
A file overwritten through the camera’s normal recording cycle before the owner appreciated its significance presents a different situation from footage intentionally deleted after a collision because it was unfavourable.
Even where the recording no longer exists, Rule 30.03 can require a party to disclose that the document was formerly in its possession and explain when and how it was lost.
Commercial Trucks Can Have Several Sources of Video
A commercial truck crashes usually encompass far more than a removable camera attached to the windshield.
The tractor, trailer or fleet system could contain forward-facing footage, inward-facing driver video, side or rear-camera recordings and event-triggered files connected to telematics or a fleet-safety platform.
Some systems save video only when hard braking, sudden steering or an impact triggers an event. Others retain files for a limited period under the carrier’s data policy. The recording may be controlled by the trucking company, vehicle owner, camera vendor or fleet-management provider.
That division of control can complicate preservation. A letter sent only to the driver may not reach the company that stores the recording.
Our page for Ontario truck accident lawyers explains why commercial collision investigations often extend to company records, electronic vehicle information, dispatch communications, maintenance evidence and other material beyond the police report.
Can Dashcam Footage Be Used in Pedestrian, Bicycle and Motorcycle Claims?
Yes, a r recording can show how long a pedestrian was visible, whether a driver slowed before a crossing, whether a vehicle entered a bike lane or whether a left-turning driver crossed the path of a motorcycle. A camera in a vehicle travelling behind the collision may have a clearer view than either person directly involved.
The footage still has to be assessed under the law governing the particular claim.
For example, section 193 of Ontario’s Highway Traffic Act can place the burden on an owner, driver, lessee or operator of a motor vehicle to prove that loss or damage caused by the motor vehicle on a highway did not arise through negligent or improper conduct. The section contains exceptions, including collisions between motor vehicles, and its application depends on the nature of the claim.
Is It Legal to Use a Dashcam in Ontario?
Ontario does not impose a prohibition on recording the road with a dashcam. The way the device is installed remains important.
Section 73(1) of the Highway Traffic Act prohibits driving with an object placed in, hung on or attached to a motor vehicle in a manner that obstructs the driver’s view of the highway or an intersecting highway.
Dashcams should therefore be mounted where they are not interfering with the driver’s field of vision. A compact placement behind or close to the rear-view mirror can reduce obstruction, but legality depends on whether the installation interferes with the driver’s view rather than on a universally prescribed dashcam location.
A display screen that is left on and visible to the driver could also engage section 78 of the Act, depending on the device’s function and whether a statutory or regulatory exception applies. The camera should not be configured or positioned in a way that distracts the driver from safe vehicle operation.
How Dashcam Evidence Is Handled in a Serious Injury Claim
When we are retained in a claim involving dashcam footage, the first step is to ensure that complete recording is secured, the source file and storage media are preserved, and the footage is compared with the police evidence, vehicle damage, witness accounts and the physical layout of the collision.
The investigation could also entail require identifying cameras belonging to other drivers, businesses, residences or commercial fleets. Preservation requests can then be sent before those recordings are overwritten. Where footage is not produced voluntarily, the available procedure depends on who controls it and whether litigation has begun.
The recording also needs to be reviewed for information that may not initially stand out, including audio, speed data, GPS information, timestamps and events before or after impact. An apparently favourable clip can take on a different meaning when it is compared with physical evidence or viewed as part of the complete recording.
Dashcam Footage Can Help or Hurt a Car Accident Claim
Drivers think of a dashcam as protection against the other person’s version of events. Sometimes it serves exactly that function.
The same camera can record the owner’s speed, following distance, distraction, reaction time or statements. That possibility is not a reason to avoid the footage. It is a reason to preserve the complete recording and assess it before conclusions are drawn from a selected clip.
Foster Injury Law’s Ontario car accident lawyers represent people with serious injury claims involving disputed fault, commercial vehicles, multi-vehicle collisions, pedestrians, cyclists, motorcyclists and hit-and-run drivers. Dashcam footage can become an important part of the investigation when it is secured before routine overwriting, deletion or editing changes the evidentiary record.
Frequently Asked Questions About Dashcam Evidence in Ontario
Can dashcam footage be used in an Ontario car accident lawsuit?
Yes, and we see this happening with increased regularity. The recording must be relevant and supported by enough evidence to establish that it is what the party relying on it claims it to be.
Does dashcam footage automatically prove who caused the accident?
No. It records the event from a specific viewpoint. A court can also consider witness evidence, vehicle damage, road conditions, legislation, police records and expert evidence.
Is the original memory card required for the video to be admitted?
Not necessarily. A copied recording can sometimes be authenticated through other evidence. Keeping the original file and memory card reduces disputes about the source, completeness and handling of the video.
Can edited dashcam footage be used in court?
Possibly. Editing does not necessarily make a recording inadmissible, but it can create questions about context, completeness and reliability. The complete native file should be retained even where a shorter working copy is created.
Does an incorrect timestamp make dashcam footage inadmissible?
Not usually. Other evidence can establish when and where the recording was created. An incorrect timestamp can affect the weight placed on the displayed date or time and may require additional evidence connecting the video to the collision.
Do I have to disclose footage that is unfavourable to me?
Relevant video within or formerly within a party’s possession, control or power is generally subject to disclosure in an Ontario lawsuit. The obligation is not restricted to evidence that helps the person who owns it.
Can giving the recording to my lawyer make it privileged?
Providing a document to a lawyer does not ordinarily make the underlying document privileged. The actually communications between the client and lawyer about the recording are usually privileged, but the pre-existing video remains subject to the usual disclosure rules.
Can I delete the footage before a lawsuit begins?
Relevant evidence should not be deliberately deleted once litigation is underway or reasonably anticipated. Intentional destruction of evidence can lead to an inference that it the evidence would have harmed the case of the person who destroyed the evidence. Routine overwriting that occurred before the file’s significance was recognized is examined differently.
Will my insurance company consider dashcam footage?
An insurance company will consider dashcam footage when assessing fault, vehicle damage or an injury claim.
Should I give the insurer only the collision clip?
The complete recording should first be secured. Producing only a selected clip while the surrounding footage disappears will end up creating disputes over context and completeness.
What if the other driver refuses to provide the recording?
A preservation request should be sent promptly. Once litigation begins, party disclosure rules may apply. Footage held by a non-party can potentially be pursued under Rule 30.10 where the requirements of the rule are met.
Can dashcam footage help in a hit-and-run claim?
Yes. We often see dashcam footage assisting in hit and run injury cases as it can identify the vehicle, licence plate, direction of travel, collision mechanics or witnesses who stopped nearby. The original high-resolution file should be retained because compression can obscure small details.
Should dashcam footage be posted on social media?
Preserving the recording and providing it through the police, insurance or legal process is safer. Public posting can remove context, create privacy concerns and produce additional written statements that later become evidence.
