Understanding Negligence in Ontario Car Accident Cases
When someone is injured in a car accident in Ontario, one of the first questions they often ask is, “Who was at fault for the accident?” The legal answer to that question comes down to negligence. While police officers may issue a ticket, or make a determination of fault at the scene on the motor vehicle accident report, civil liability is decided differently, and often much more carefully.
At Auger Hollingsworth Injury and Accident Lawyers, we’ve helped thousands of injured Ontarians recover fair compensation after motor vehicle collisions. Understanding negligence is the foundation of every personal injury claim. Here’s what it means and how it’s proven in practice.
What Is Negligence?
Negligence means carelessness that causes harm to someone else. In a motor vehicle collision, negligence occurs when a driver fails to act like a reasonably prudent driver would act in the same circumstances, and that failure causes injury or damage.
The law of negligence has four key elements:
- Duty of Care – Every driver on Ontario roads owes a duty to others to drive safely and obey the rules of the road.
- Breach of Duty – A driver breaches that duty by doing something (or failing to do something) that a reasonably careful driver would not do. Examples include speeding, distracted driving, failing to yield, or running a red light.
- Causation – The negligent act must cause the accident or injury. If the accident would have happened anyway, there may be no legal causation.
- Damages – The injured person must suffer actual harm, such as physical injuries, income loss, or pain and suffering.
All four elements must be proven on a balance of probabilities — meaning it is more likely than not that negligence occurred. This is very different from the criminal or traffic court standard, which requires proof beyond a reasonable doubt.
The Difference Between Police Fault and Legal Negligence
After an accident, many people assume that if the police issued a ticket or noted who was “at fault,” that’s the final word. The police determination of fault and the civil law determination of negligence are really two separate things.
Police Fault Determinations
When police attend a crash, they may:
- Investigate the scene,
- Speak to drivers and witnesses,
- Review vehicle damage, and
- Issue one or more traffic tickets under the Highway Traffic Act.
The officer’s primary role is to enforce traffic laws, not to assign civil liability. Their findings are based on what they can determine at the scene — often within minutes, without access to expert analysis or full witness evidence.
A traffic ticket means the officer believes a driver violated a specific road rule. It doesn’t automatically mean that driver will be found negligent in a lawsuit or insurance claim. Similarly, the absence of a ticket does not mean a driver is free from fault. Most of the time in motor vehicle accidents there are no charges or tickets. That doesn’t mean there is no claim!
Civil Fault Determinations
In civil law, the question is broader and deeper: Did the driver act reasonably under all the circumstances? A court (or insurance adjuster) considers all available evidence — photos, witness statements, expert reports, and even the road and weather conditions — to decide whether the driver breached the duty of care.
A driver could, for example, be found negligent in a civil trial even if no ticket was issued. Conversely, someone could receive a ticket but not be found legally negligent if the evidence shows their actions were reasonable in context. (It is uncommon for someone who received a ticket not to be found negligent, but not impossible.)
The key takeaway: police fault and civil negligence are not the same thing.
How Negligence Is Proven in a Car Accident Claim
To succeed in a personal injury lawsuit, the injured person (the plaintiff) must prove that another party’s negligence caused their injuries. Evidence may include:
- Accident scene photographs and vehicle damage photos
- Witness statements from drivers, passengers, or bystanders
- Police reports and motor vehicle collision reports
- Expert accident reconstruction or engineering analysis
- Medical evidence showing the link between the crash and the injuries
Lawyers at Auger Hollingsworth carefully gather and organize this evidence to build the strongest possible liability case. Even when police fault reports are inconclusive, civil negligence can often be established with a detailed investigation.

When More Than One Person Is at Fault
Ontario law recognizes that sometimes both drivers share responsibility for a collision. Under the Negligence Act, if more than one person is at fault, each person is liable for a portion of the damages according to their degree of fault.
For example:
- If one driver was speeding and the other failed to yield, a court might apportion (divide) fault 60/40.
- The injured driver can still recover compensation, but the total damages are reduced by their percentage of responsibility.
For example, if your damages are assessed at $100,000 but you were assessed as being 40% at fault for the accident, your damages would be reduced to $60,000.
This system is known as contributory negligence. It allows fair outcomes even when fault isn’t black and white, which is often the case on Ontario roads.
Common Examples of Negligence in Ontario Motor Vehicle Collisions
Here are a few everyday examples of negligent driving behaviour that can give rise to a personal injury claim:
- Distracted driving: Texting, adjusting the GPS, or eating while driving.
- Speeding or aggressive driving: Failing to adjust speed for weather or traffic conditions.
- Failure to yield or improper turns: Ignoring right-of-way rules at intersections or crosswalks.
- Following too closely: Rear-end collisions are among the most common forms of negligence.
- Impaired or fatigued driving: Driving under the influence of alcohol, drugs, or extreme fatigue.
- Ignoring pedestrians or cyclists: Failing to maintain a proper lookout or safe passing distance.
Each of these actions represents a breach of the duty of care owed to others on the road.
Negligence and Ontario’s No-Fault Insurance System
Ontario’s automobile insurance system is sometimes described as “no-fault,” but that term can be misleading. It refers to accident benefits, which every injured person can claim from their own insurer regardless of fault.
However, if another driver’s negligence caused your injuries, you may also have the right to sue that driver for additional compensation — such as pain and suffering, income loss beyond the statutory benefits, and other out-of-pocket expenses.
This is why determining negligence is so important: it governs whether you can pursue a civil claim in addition to your no-fault benefits.
Why Legal Advice Matters
Understanding and proving negligence can be complex. Insurance companies often dispute fault or argue that an injured person contributed to their own losses. Meanwhile, the physical, emotional, and financial toll of a serious accident can make it difficult to focus on the legal process. Plus, how do you know what evidence you need and how to gather it? Much of this work is done by investigators and engineers.

Key Takeaways
- Negligence means a failure to take reasonable care that causes harm.
- A police ticket or fault report is not the same as a finding of legal negligence.
- Civil liability is determined by a court or through settlement negotiations based on all the evidence.
- Contributory negligence may reduce, but does not necessarily eliminate, your right to compensation.
- Even in Ontario’s no-fault system, negligence determines whether you can pursue additional damages.
