Reporting a Collision in Ontario: When You Must Call Police

Under Ontario's Highway Traffic Act, you must report a collision to the police if anyone is injured, or if the total damage to all vehicles and property appears to be more than $2,000. In many areas, minor collisions without injuries are reported at a collision reporting centre rather than at the scene.

At the scene

1. Check for injuries and call 911 if anyone is hurt.
2. Move vehicles out of traffic if it is safe and they can be driven.
3. Exchange names, addresses, phone numbers, licence numbers, plates and insurance details.
4. Take photos of the vehicles, plates, road, signs and conditions.
5. Get the names and phone numbers of witnesses.

Don't

• Leave the scene before exchanging information: failing to remain is a serious offence.
• Admit fault or sign anything at the scene.

After

• Report the collision as required, usually within 24 hours at a reporting centre.
• Tell your insurer promptly.
• If you were injured, see a doctor and keep records.

Charged?

Collisions often lead to charges such as careless driving or following too closely. Get advice before you pay or plead.
