We have to be careful in calling this information public. As you have just said, it is still possible to identify the person associated with a car, their behaviour, and so on. So, even if the information is called public, we have to wonder whether the information is actually personal, and what authority a given department has to collect it. It varies from department to department. Even though the information is in the public domain, collecting it has to be linked to a mandate of the department in question. That is a very important condition in the current legislation. It could be made stronger, along the lines of some recommendations we made in connection with amending the Privacy Act.
In summary, we have to be careful with data in the public domain. We have to make sure that each department collecting and using the information actually has a mandate to do so.
