A serious car accident can leave you overwhelmed, injured, and unsure of what to do next. The first 72 hours are often critical, not only for your health but also for protecting your legal rights. Seeking prompt medical attention, reporting the collision, notifying your insurance company, preserving evidence, and understanding your accident benefits can all affect your recovery and any future personal injury claim.
Whether the collision occurred in Toronto, Brampton, Vaughan, Mississauga, Markham, Richmond Hill, Newmarket, Bradford, or anywhere else in Ontario, taking the right steps in the hours and days that follow can help protect your health, preserve your legal rights, and allow you to focus on your recovery.

Why Are the First 72 Hours So Important?
The first few days after a serious motor vehicle accident can have a significant impact on your recovery, your insurance claim, and any future legal claim.
Not all injuries are immediately apparent. Conditions such as concussions, whiplash, internal injuries, and psychological trauma may take hours or even days to develop, and adrenaline can temporarily mask pain and other symptoms.
The first 72 hours are also an important time to preserve evidence. Photographs of the scene, vehicle damage, roadway conditions, witness information, dashcam footage, and early medical records can all become more difficult to obtain as time passes.
You should also notify your insurance company as soon as possible so the accident benefits process can begin. Starting the process early can help avoid unnecessary delays in accessing the benefits that may be available to you.
What Should You Do Immediately After a Serious Car Accident?
Prioritize Your Safety
If you are able, move to a safe location away from traffic and call 911 if anyone has been injured or there is an immediate safety concern.
Depending on the circumstances, Ontario law may require the collision to be reported to police. Officers may attend the scene or direct you to report the collision at a Collision Reporting Centre, depending on the nature of the accident.
If you are seriously injured, your priority should be getting emergency medical care. If possible, avoid moving unless it is necessary for your safety or directed by emergency responders.
Seek Medical Attention
Even if you believe your injuries are relatively minor, it is important to be assessed by a healthcare professional as soon as possible.
Seeking medical attention early helps identify potentially serious injuries while creating important medical documentation from the outset. Be sure to follow your healthcare provider’s recommendations and attend any recommended follow-up appointments.
Some injuries and symptoms may not appear until hours or even days after the collision. If you notice new or worsening symptoms, seek medical attention as soon as possible.
Gather Information If It Is Safe
If it is safe to do so and your injuries allow, gather as much information as you can before leaving the scene.
Take photographs of the vehicles, the accident scene, roadway conditions, weather, traffic signs, visible injuries, licence plates, and any property damage. If there were witnesses, try to obtain their names and contact information.
If your vehicle is equipped with a dashcam, preserve the footage as soon as possible to prevent it from being accidentally overwritten.
What Should You Do During the Next 24 Hours?
Notify Your Insurance Company
Ontario has a no-fault accident benefits system. This means that regardless of who caused the collision, you may be entitled to certain accident benefits through the appropriate automobile insurer.
Notify your insurance company as soon as possible after the collision so the accident benefits process can begin. They can provide the forms needed to apply for any benefits that may be available to you.
Depending on your circumstances, accident benefits may include medical and rehabilitation benefits, income replacement benefits (if applicable to your policy), attendant care benefits, and other benefits available under the Statutory Accident Benefits Schedule.
Begin Keeping Records
One of the most important things you can do after a collision is to keep organized records of everything related to your injuries and recovery.
Save copies of your medical records, prescriptions, treatment recommendations, receipts, insurance correspondence, photographs, and any information relating to missed time from work. It is also helpful to keep a journal documenting your symptoms and how your injuries affect your daily life.
These records can be valuable if questions arise later about your injuries, treatment, or losses.
What Should You Do During the Following 48 to 72 Hours?
Continue Following Medical Advice
Recovery does not always follow a straight line. Some symptoms improve quickly, while others may take time to appear or worsen over the days following a collision.
Continue attending scheduled appointments, follow your healthcare provider’s treatment recommendations, and report any new or worsening symptoms. Early treatment not only supports your recovery but also creates an accurate medical record of your condition over time.
Monitor Symptoms Carefully
Some injuries become more noticeable after the initial shock of the collision has worn off.
If you experience symptoms such as persistent headaches, dizziness, confusion, memory problems, neck or back pain, numbness, sleep disturbances, emotional changes, or increasing pain, discuss them with your healthcare provider as soon as possible.
Do not ignore new or worsening symptoms simply because they did not appear immediately after the collision.
Consider Speaking With a Personal Injury Lawyer
Not every collision requires legal representation. However, speaking with a personal injury lawyer early can be helpful if you have suffered serious injuries, are unable to work, have ongoing medical needs, or if fault for the collision is in dispute.
A personal injury lawyer can explain the difference between accident benefits and a civil claim, discuss applicable limitation periods, and help you understand what documentation may become important later.
Speaking with a lawyer early does not mean you are starting a lawsuit. It simply gives you the opportunity to understand your rights, preserve important evidence, and make informed decisions while you focus on your recovery.
Understanding Ontario’s Accident Benefits
Ontario’s accident benefits system provides certain no-fault benefits to people injured in motor vehicle accidents, regardless of who caused the collision.
The benefits available to you will depend on several factors, including the severity of your injuries, the insurance policy in effect, and any optional coverages that were purchased.
For individuals with catastrophic injuries, additional medical, rehabilitation, attendant care, and future care funding may become available under Ontario’s legislative framework.
Ontario’s accident benefits system can be complex, and the rules have changed over time. Understanding the benefits available to you can help ensure you receive the support you may be entitled to following a collision.
What About a Personal Injury Claim?
In some cases, you may also have the right to bring a personal injury claim against the at-fault driver.
A civil claim is separate from your accident benefits claim. Depending on the circumstances, you may be able to seek compensation for pain and suffering, lost income, future care costs, and other losses recognized under Ontario law.
In most cases, Ontario’s Limitations Act, 2002 sets a two-year limitation for starting a civil claim. However, exceptions may apply depending on the circumstances, so it is important to understand the deadlines that apply to your case.
Common Mistakes to Avoid
The days following a serious collision can be overwhelming. Avoiding a few common mistakes can help protect both your recovery and your legal rights.
- Do not delay seeking medical attention simply because you initially feel “okay.”
- Follow your healthcare provider’s treatment recommendations and attend any recommended appointments.
- Keep all documents related to the collision, including medical records, receipts, and insurance correspondence.
- Be cautious about providing recorded statements or signing documents before fully understanding your rights.
- Avoid discussing the collision or your injuries on social media, as those posts may later become relevant to your claim.
