No one tells insurance companies about a ticket you may have received. The insurance only learns of your driving habits from either claims or accidents and your driving record.
In Ontario your driving record is called an “Abstract”. Your driving record is a history of traffic tickets you have received in the previous three (3) years.
The record is available from the Ministry of Transportation (MTO) for a fee.
Upon renewal the insurance will obtain a copy of the abstract to see if there have been any accumulation of driving convictions, and then base your rates upon that.
