How long do I have to report an accident in Ontario? In Ontario, you should report any accident within 24 hours of it occurring. Even if the damage is minimal (less than $2000) and you decide not to file an insurance claim, you will have a record of the accident.
Ontario law requires that you notify the police immediately if anyone is injured in a car accident or the damage to all vehicles appears to be greater than $2,000. Otherwise, you have 24 hours to report a collision to a Collision Reporting Centre.
