Unfortunately, minors don't have credit reports in terms of protecting those.
For example, at Equifax, we have a stolen SIN database where we could enter minors' information, a SIN number, that has been compromised. When a fraudster tries to use your daughter or son's information, and they're under age, that would trigger the institution to say that this SIN number has been stolen or lost by an individual. Since children don't have a credit file, it's a lot tougher.
Building the identity—and Tara working with fraud and the associations who deal with fraud can elaborate—simply put, they start with the SIN, which gives a concrete basis to the identity or the fictitious identity. With that they apply, let's say, for a cellphone and they get the hardware. Then they post it on Kijiji or something and meet you near a subway to sell that hardware. They do that over and over again. These identities are faceless crimes and they don't exist. They start simple and build up that credit, perhaps go to a bank and get a small loan, or get credit cards. They work using one or two pieces of identity. When your child applies for their first credit facility years down the road, all of a sudden they find out that their SIN number has been compromised and used over and over again.
