What to Do After a Motor Vehicle Accident in Ontario

Being involved in a motor vehicle accident can be overwhelming. In Ontario, there are key steps you should take immediately to protect your well-being and legal rights. The following guide outlines what to do, from ensuring everyone's safety to following Ontario's legal requirements.

1. Ensure Safety and Seek Medical Attention

Prioritize health and safety. Check yourself and others for injuries right away. If anyone is hurt, call 911 immediately for emergency medical help. Even if injuries seem minor, it is wise to get a medical evaluation as soon as possible, since some injuries such as whiplash or concussions may not show symptoms right away. Your health is the top priority, and prompt treatment also creates a medical record of the injury which can be important later.

If it is safe, move your vehicle out of traffic to prevent further collisions. Turn on hazard lights and, if available, use cones or flares to alert other drivers. Staying calm and collected will help you handle the situation more effectively.

2. Contact Police (Know When to Report)

Determine if police need to be contacted. In Ontario, you are legally required to report certain accidents to the police. Collisions involving any injuries or combined property damage over $5,000 must be reported to police as soon as possible. If someone is hurt, or if the damage to vehicles or property seems significant, you should call the police from the scene.

For minor fender-benders where no one is injured and damage is clearly below the $5,000 threshold, police may not attend the scene. However, you are still expected to report the incident. In many jurisdictions in Ontario, drivers must visit a Collision Reporting Centre within 24 hours for accidents that do not require immediate police presence. A Collision Reporting Centre is a facility where you can file an official accident report and have damage documented once everyone is safe and the situation is under control.

When speaking with police or at the collision centre, stick to the facts of what happened. Be polite and cooperative, but avoid speculating about fault. Ontario uses a no-fault insurance system, meaning your own insurance will handle many of your benefits regardless of who caused the accident, but fault can still affect future insurance rates and any legal claims. The police report will be important documentation, so ensure the information recorded is accurate.

3. Exchange Information and Document the Scene

Ontario law requires all drivers involved to remain at the scene and exchange identifying information with each other. After checking for injuries and calling for help, exchange information with the other driver or drivers involved. This step is crucial for insurance and any potential legal claims. Be sure to collect the following details:

  • Names and contact information of all drivers involved
  • Driver's licence details and issuing jurisdiction
  • Vehicle information including make, model, year, color, and licence plate number
  • Insurance details including the company name and policy number
  • Registered owner's name and address if different from the driver

It can be helpful to take photographs of the other driver's documents with their permission to ensure accuracy. Also take wide-angle photos of the accident scene and close-ups of vehicle damage. Capture positions of the vehicles, skid marks or debris, and any road signs or signals nearby. This evidence can be very valuable later when dealing with insurance or any dispute about what happened.

If there are witnesses, ask for their names and contact information. Independent witness accounts might help corroborate your version of events. While exchanging information, be courteous and calm. Do not argue with the other driver or admit fault. Even saying something like "I'm sorry" could be misunderstood as an admission of liability. Simply focus on gathering the necessary details. By law, you must provide your information to anyone affected by the accident or to police on request. Likewise, the other driver is required to provide theirs.

4. Notify Your Insurance Company

After dealing with the immediate scene, you will need to inform your auto insurance provider about the accident promptly. Ontario law requires you to report an accident to your insurance company within seven days, or as soon as is reasonably possible. Failing to notify your insurer in a timely manner could lead to problems, and the insurance company may refuse to honour your claim if you wait too long.

When you call your insurer or broker, provide them the facts of what happened. They will likely ask for details such as when and where the accident occurred, a description of what happened, the other driver's information, and whether there were any injuries. It is helpful to have the information you collected at the scene at hand, such as the police report number, other driver's name, and insurance details.

Ontario operates under a no-fault insurance system, meaning you will typically deal with your own insurance company for vehicle damage and accident benefits, even if the other driver was at fault. Fault is still determined, and can affect your insurance record, but initially your insurer handles your claim regardless of fault. They will guide you through filing the necessary claim forms.

If you are injured, ask your insurer about Accident Benefits forms. These benefits cover medical expenses and income replacement, and are available to anyone injured in a crash regardless of who caused it. There are deadlines, often 30 days to submit the application, so starting the insurance process quickly is important. When speaking with insurance adjusters, stick to the facts just as you did with police. Do not speculate about blame or downplay any injuries. If you are not sure about something, it is fine to say you will provide more information later.

5. Consider Legal Counsel (Know Your Rights)

Car accidents can raise complex legal and insurance issues, especially if you or a loved one suffered injuries. While not every accident requires a lawyer, getting professional legal advice can be very beneficial in many cases. An experienced Ontario personal injury lawyer can explain your rights under the Insurance Act, such as your entitlement to accident benefits, and advise if you have a case for additional compensation from an at-fault driver.

In Ontario, you generally have the right to sue an at-fault driver for pain and suffering and other losses if your injuries are serious and meet certain legal thresholds. A lawyer can evaluate whether your situation meets those thresholds and help you understand the limitation periods for claims. They can also deal with insurance companies on your behalf. Insurers have teams of adjusters and lawyers, so having your own legal advocate levels the playing field.

Consulting a lawyer does not mean you are automatically suing someone. It helps you make informed decisions. Many personal injury law firms, including UL Lawyers, offer a free initial consultation so you can discuss your accident and injuries with a legal professional at no upfront cost.

You may especially need a lawyer if you suffered serious injuries, if fault is being disputed, if you feel the insurance settlement offer is unfair, or if you are unsure about the process. A lawyer can handle communications with insurance, help gather evidence such as medical reports or expert opinions, and advocate for full compensation for your medical bills, lost income, and pain and suffering. This allows you to focus on recovery while they handle the legal complexities.

Conclusion

Being in a motor vehicle accident is stressful, but knowing the proper steps to take can protect your health, your finances, and your legal rights. In summary, make sure everyone is safe and get medical help first, report the accident to the police or collision centre as required by Ontario law, exchange information and document evidence, inform your insurance company promptly, and do not hesitate to seek legal advice if you have any questions or injuries.
