The PIPEDA definition is intended as a privacy protection and covers information that is simply about someone. It could be information about their shopping preferences or whatever. What we're dealing with here is a more specific focus on information that actually identifies the person, the sort of information that could be used to then personate them or commit fraud using their identity information. It's specifically crafted to cover only that information that actually identifies the person, as opposed to simply information about the person. It's a different purpose, a different focus.
