Ease of retrieval is a moving target. Think of the history of libraries and how arduous it used to be look something up. At one time they had card catalogues, so you had to look it up and then wander through and find your book. Things are changing every decade in terms of how easy it is to retrieve information, so I don't know that we'd want to create legislation at this moment in time based just on the fact that it's easier to retrieve information now. That's going to change. Hopefully, it's going to become embedded under our skin.
Retrieving information is going to become a very seamless, painless experience, and that's the beauty of PIPEDA: it's technology neutral and isn't based on any particular point in time and technology.
