CIPPIC has not looked at that information, but it has come to me. I can think of a couple of cases in which people have complained about exactly that issue, about providing detailed, sensitive, personal information to Statistics Canada, people who didn't want to. I believe there are a number of people who have filed formal complaints with the Privacy Commissioner about that, but as you say, there is a law requiring them to provide the information. It would be interesting to hear from Statistics Canada and the Privacy Commissioner on this issue. I've not looked at it in any depth, other than what the law requires right now.
The way it is at least theoretically resolved now is that there are theoretically constraints on Statistics Canada, so it does not allow that information to be used or abused in other ways. In the end, Statistics Canada produces very valuable information for Canadians and the government on the basis of the census and labour force surveys. There is a rationale for that, which I think has some merit, but the short answer to your question is that neither the clinic nor I have looked at it in any greater depth.
