I explained earlier when I was asked a similar question that some days I remember wonderful horror stories. Some days I remember them less. This happens to be a day when horror stories are not springing to mind, partly because I like to put them out of my mind, because they're often so appalling they shouldn't have happened. I think if you just pay attention to your daily newspapers for the next month or so, you'll come up with lots of privacy horror stories--that's how we refer to them--or privacy disasters, things that shouldn't have happened.
What is so important is that 30% or 40% of the population, it is estimated, is very sensitive about their personal privacy. You ask them for their social insurance number, and they get really excited, even though I know if you have a social insurance number you can call up Bathurst, New Brunswick, where the social insurance number registry is, until you're blue in the face, and they're not going to tell you anything.
So one of the reasons to get sound privacy management in place for the federal government, based on strong legislation, is to have reduced paranoia in the population, to be able to feel that in fact the Government of Canada is respecting your personal information, taking it for legitimate purposes, using it in authorized ways, destroying it when it should be destroyed, linking it when it's supposed to link it to profile you for disease risk, for example.
I'm incredibly enthusiastic about what I gather are some forthcoming initiatives to monitor larger groups of the population for health over longer periods of time. That can be done in a very privacy-sensitive way, and it's very much in the public interest, so it's not as though I'm sitting here as a Luddite.
