What to Do After a Car Accident in Ontario

A car accident can upend your life in seconds. Whether it's a minor fender-bender or a serious collision, the decisions you make in the hours and days that follow will directly affect your health, your insurance claim, and your ability to recover fair compensation.

Ontario has specific legal requirements governing accident reporting, insurance notification, and legal timelines. Getting these steps right protects you, while getting them wrong, or skipping them, can give insurers grounds to reduce or deny the benefits you're entitled to.

This guide walks Ontario residents through exactly what to do after a car accident, from the scene through to legal consultation, in the order it needs to happen.

Key Takeaways

• Call 911 immediately if there are injuries, fatalities, or vehicle damage that appears to exceed $5,000. Move vehicles off the road and document the scene thoroughly before anything is disturbed.
• Report to police or a Collision Reporting Centre within 24 hours if required, since late reporting can complicate your insurance claim and legal proceedings.
• Notify your own insurer promptly to activate your Statutory Accident Benefits (SABs), but provide only factual information and don't speculate about fault or minimize your injuries.
• See a doctor as soon as possible, even if you feel fine. Many serious injuries, including concussions and spinal trauma, aren't immediately obvious, and a gap in medical care is one of the most common arguments insurers use to minimize claims.
• Don't sign any release or settlement offer without first consulting a personal injury lawyer. Ontario's two-year limitation period applies, but many deadlines are much shorter.

Step 1: Prioritize Safety and Call for Help

The moments immediately after a collision are the most critical, so call 911, check for injuries, and make the scene safe before anything else.

Check for Injuries and Call 911

Your first obligation at any accident scene is to ensure everyone's safety. Before you reach for your phone to photograph the scene or exchange information, assess whether anyone is hurt.

• In Ontario, you're legally required to call police when there are injuries, fatalities, or damage that appears to exceed $5,000. When in doubt, call anyway.
• Do not move an injured person unless they face immediate danger, such as fire or ongoing traffic risk, as moving someone with a spinal injury can make it significantly worse.
• Turn on your hazard lights immediately, and if you have flares or warning triangles and it's safe to deploy them, do so to alert oncoming traffic.

Document the Scene and Then Move Vehicles

Once you've confirmed everyone is safe and emergency services have been called, your next priority is documentation. Photograph everything before vehicles are moved and before details fade.

• If no injuries are present and vehicles are driveable, Ontario law requires you to move them off the roadway to avoid blocking traffic, but do this only after you've photographed everything in place.
• Photograph all vehicles from multiple angles, including licence plates, visible damage, and the surrounding scene, and capture road conditions (e.g., snow and ice, potholes), weather, traffic signals, signage, and any skid marks.
• Exchange full name, driver's licence number, licence plate, insurer name, and policy number with every other driver involved.
• Collect contact information from any witnesses before they leave the scene, since an independent witness account can be decisive in disputed-fault situations.

Step 2: Report the Accident

Ontario law requires accident reporting within specific timeframes, but there are circumstances where reporting late is permitted and still necessary.

Report to Police or a Collision Reporting Centre

If police attended the scene and took a report, ask for the report number before you leave, since your insurer will need it. If police didn’t attend, which is common in minor collisions, you may still have a reporting obligation:

• If damage appears to exceed $5,000 and police didn't attend, report to a Collision Reporting Centre (CRC) within 24 hours in most Ontario municipalities. Bring both vehicles if possible.
• An accident report created at the time of the accident creates a formal record that's difficult for insurers to dispute later, so file one even if you don't think you need it.
• The CRC will issue a report number, so keep a copy for your insurer and your records.

Can You Report a Car Accident After the Fact?

Yes, late reporting is possible in Ontario, but it comes with complications. Understanding the rules helps you act appropriately even if time has passed since the accident.

• Under Ontario's Insurance Act, your insurer requires you to report an accident "as soon as practicable (capable of being done)," and unreasonable delay can give them grounds to reduce or deny your Statutory Accident Benefits. Typically this is within 7 days of the accident occurring.
• Late reporting is common and legally defensible when injuries emerged or worsened in the days after the accident, which is typical with soft tissue injuries, concussions, and spinal trauma that often don't produce obvious symptoms at the scene.
• If you delayed reporting because you weren't aware of your injuries at the time, document the timeline carefully. A personal injury lawyer can help you navigate the implications of delayed reporting in your specific situation.

Step 3: Notify Your Insurance Company and Understand Your Rights

In Ontario, every accident victim has access to two streams of potential compensation:

• Statutory Accident Benefits (SABs) through your own insurer.
• A Tort claim against an at-fault driver.

Notifying your insurer promptly activates both, but what you say in that first call matters.

What to Tell (and Not Tell) Your Insurer

Your insurer is not the same as your advocate, so report the accident as soon as possible, but be deliberate about what you share.

• Report the accident as soon as possible, as delaying can jeopardize your Statutory Accident Benefits, which cover income replacement, medical and rehabilitation expenses, and attendant care.
• Provide factual information only, including when and where the accident occurred, who was involved, and the basic sequence of events. You are not required to give a recorded statement at this stage.
• Don’t apologize, speculate about fault, or characterize the severity of your injuries before you've been medically assessed, as statements made before a diagnosis is in hand can be used against you.
• The at-fault driver's insurer may contact you. You have no obligation to speak with them without legal representation. Politely decline until you've spoken with a lawyer.

Ontario has firm deadlines governing accident benefits and legal proceedings, and missing them can permanently eliminate rights you'd otherwise have.

Step 4: Seek Medical Attention Immediately

Get medical attention as soon as possible after a car accident, since it protects your health and creates the documentation your claim depends on. Many of the most serious injuries, including concussions, spinal injuries, and internal bleeding, aren't immediately obvious.

Don't wait to see if symptoms develop. See a doctor that day or go to an emergency department and tell your treating physician that your injuries are accident-related, documenting every symptom even if it seems minor.

What Tests Are Done After a Car Accident?

Depending on the mechanism of the collision and your reported symptoms, your physician may order any of the following:

• Physical examination to assess visible injuries, range of motion, neurological signs, and pain response
• X-ray for fractures, dislocations, and skeletal damage
• CT scan for brain injury, internal bleeding, spinal damage, and abdominal trauma
• MRI for soft tissue injuries, disc herniation, and ligament damage not visible on X-ray
• Neurological or cognitive assessment for traumatic brain injury and post-concussion symptoms
• Psychological screening for anxiety, PTSD, and depression, which are common and compensable after serious collisions

Inform your treating physician that your injuries are accident-related and do not downplay your symptoms. What seems like mild soreness at the scene may be the start of a long-term condition that significantly affects your earning capacity and quality of life.

Why Early Medical Documentation Is Critical

The quality and timing of your medical documentation can determine the difference between a full recovery of your losses and a lowball settlement that doesn't come close to covering them.

• A gap between the accident date and your first medical visit is one of the most common arguments insurers use to minimize injury claims, suggesting your injuries weren't serious or weren't caused by the accident.
• Many symptoms, including soft tissue injury, concussion effects, and psychological trauma, emerge or worsen in the days following a collision, and early documentation establishes the causal link between the accident and your condition.
• Long-term or catastrophic injury is often not immediately apparent at the scene, so a thorough assessment from the outset protects you against premature settlement before the full extent of your injuries is medically established.

Step 5: Understand How Fault Is Determined After a Car Accident

Fault allocation in Ontario directly affects your tort claim and insurance premiums. Here's how insurers and courts determine it, and what happens when fault is assigned to you.

The Ontario Fault Determination Rules

Ontario doesn't leave fault allocation to guesswork, since insurers are required to follow a standardized regulatory framework.

• Ontario insurers apply the Fault Determination Rules (O. Reg. 668), a regulatory framework that governs how fault is allocated based on the specific circumstances of a collision.
• Fault can be apportioned in increments of 0%, 25%, 50%, 75%, or 100%, depending on who did what and when.
• Common scenarios covered include rear-end collisions, left-turn accidents, lane-change collisions, and intersection accidents, each with prescribed fault allocations based on the facts.
• Witness statements, photographs, video footage (including dashcam and traffic cameras), and the police report all factor into the determination.

What Happens After a Car Accident That Is Your Fault?

Being found at fault doesn't mean you're without recourse, as Ontario's system preserves important rights even for drivers who caused the collision.

• Even if you're found fully at fault, you retain the right to Statutory Accident Benefits through your own insurer, since SABs are available to every accident victim in Ontario regardless of how the collision occurred.
• Your tort claim for pain and suffering will be reduced proportionally to your degree of fault under Ontario's contributory negligence rules, so a 25% fault finding means a 25% reduction in your tort damages.
• If the other driver was also partially at fault, you may still have a viable tort claim, even if you share responsibility. Don't assume otherwise before speaking with a lawyer.

Step 6: Protect Your Legal Rights and Consult a Lawyer

The steps above protect your health and your documentation, but this step protects your compensation. Most accident victims who work with an experienced personal injury lawyer recover significantly more than those who navigate the process alone.

Steps to Take After a Car Accident to Protect Your Claim

From the moment of the accident forward, there are specific actions that preserve the value of your claim, and specific mistakes that can undermine it.

1. Don’t sign any release or accept any settlement offer from an insurer without first consulting a personal injury lawyer, since a signed release is permanent and cannot be revisited regardless of how your condition changes.
2. Keep a daily journal documenting your symptoms, pain levels, missed work, and limitations on daily activities, as this kind of contemporaneous record is powerful evidence that's difficult for an insurer to challenge.
3. Avoid discussing your accident or injuries on social media, since insurers actively monitor social platforms and have used posts and photographs to argue that claimants weren't as seriously injured as they claimed.
4. Preserve all evidence, including accident photographs, medical records, prescription and treatment receipts, paystubs showing income loss, and all correspondence with your insurer.

When to Call a Lawyer After a Car Accident

You should call a personal injury lawyer as soon as possible after a car accident, ideally before you speak extensively with your insurer. The earlier you get legal guidance, the better positioned you are to protect the full value of your claim.

Call immediately if any of the following apply:

• You've sustained injuries of any kind, even if they seem minor at the time
• The other driver disputes fault or their account of the accident contradicts yours
• A family member was killed or catastrophically injured in the collision
• A pedestrian or cyclist was involved
• A road defect, signage failure, or municipal infrastructure issue may have contributed to the accident
