Possibly. I haven't thought about the exact pieces of legislation that need to be amended.
As I responded in answering an earlier question from Ms. Hepfner, I think we need to start from a principles base, augmented with a few provisions to ensure that general principles cannot lead to overly generous interpretation. It means definitely PIPEDA and the Privacy Act, and potentially the Criminal Code.
There is a lot of authority in the common law for the use of various technologies. Potentially, the Criminal Code could be examined from the perspective of restricting some of these common law powers, but I haven't thought this through seriously.
