Think of your Carrier Profile as your safety record. Just as your drivers have driving records, you have an on-road performance record as a carrier. The profile is made up of records from the Ministry of Transportation and Infrastructure and ICBC, and other jurisdictions. So if your driver has an accident or gets a ticket in another province, for example, it will also appear on your profile.
