A police report after a car accident in Ontario can preserve important evidence, but the correct reporting route depends on the circumstances. Record the scene, exchange required information, obtain available records and avoid guessing about fault. This guide explains collision reporting centres and evidence preservation.
Key takeaways: Report appropriately, preserve photographs and witness details, keep the report information and compare it with your own records.
Attending police versus self-reporting
Ontario law requires certain collisions to be reported to police. Depending on the circumstances and the local police service, officers may attend the scene, or drivers may be directed to a collision reporting centre to complete a report on their own, often a day or more later. Lawyers and claimants have observed that self-reporting is increasingly common, including in some accidents involving injuries.
Self-reporting is convenient, but a self-report is only as good as the information each driver provides. No neutral officer has examined the vehicles in place, spoken to witnesses at the scene or recorded the conditions at the time.
What can be lost when no one investigates the scene
When police attend promptly, they may record details that are difficult or impossible to reconstruct later, including:
• weather and lighting, including sun glare and visibility;
• traffic flow and congestion at the time;
• road layout, slope, curves and lane markings;
• road hazards, construction and signage;
• tire tread and traction, and the general condition of each vehicle;
• obstructed sightlines and possible distractions;
• the final resting positions of the vehicles and debris.
Once the vehicles are moved and the scene is cleared, much of this information is gone. Months or years later, when fault is disputed, the parties may be left with competing memories.
The risk of driver substitution
A further concern is that the person who reports the accident is not always the person who was driving. Where no officer confirms who was behind the wheel, there is a risk that a driver who was suspended, unlicensed, impaired, uninsured or excluded from the policy could be replaced in the report by another person. Driver identity can affect both fault and insurance coverage, so it is important to note who was actually driving each vehicle and to tell police or the reporting centre if you believe the information given is wrong.
Why police evidence carries weight
In a civil trial, a judge or jury decides fault on all of the evidence. Police officers are generally viewed as neutral, and their observations and reports are often given significant weight. That is helpful when the report is accurate. When the report is incomplete or based on one driver’s account, it may point decision-makers in the wrong direction, and it can take considerable effort to correct.
A police report is not determinative. It can be challenged with other evidence, but the earlier that other evidence is preserved, the better.
A practical evidence checklist
If it is safe to do so, and your health allows, consider the following at or soon after the scene:
• Photograph the vehicles before they are moved, the damage, the road, signage, skid marks, debris and weather conditions.
• Exchange information with the other driver, including licence, insurance and plate details. The Highway Traffic Act sets out what drivers must provide on request.
• Photograph the other driver’s licence and insurance card if they agree, and note who was actually driving.
• Collect names and phone numbers of independent witnesses.
• Save your own dashcam footage and ask nearby homes or businesses about video quickly, as recordings may be overwritten.
• Write down your own account as soon as possible, including times, speeds and what you saw.
• Seek medical attention and tell your doctor about all of your symptoms.
• Ask for the police report or collision report number and request a copy; the process differs between police services.
If you were taken to hospital and could not report the accident yourself, let your insurer know and, where needed, contact the police service or reporting centre about how to provide your account.
How a lawyer may use the scene evidence
When fault is disputed, the evidence gathered in the first days after a collision can be used in several ways. Photographs and video may help an accident reconstruction expert estimate speeds, sightlines and points of impact. Witness statements taken while memories are fresh are often more reliable than accounts given years later at trial. Records of weather and lighting can be compared with the drivers’ descriptions. If the police or collision report contains an error, such as the wrong direction of travel or the wrong driver, this evidence may help show that the report should be given less weight.
It may also be possible to obtain additional records, such as notes made by the officers who attended, 911 call records, or vehicle data, depending on the circumstances and the applicable procedures. Some of these records are kept only for a limited time, which is another reason to act promptly. Telling your own insurer about any concerns with the report, in writing, also creates a record that you raised the issue early.

What is a collision reporting centre?
It is a facility where drivers report collisions themselves, usually after the event, instead of having police attend the scene. Not every police service uses them.
