There's the lack of transparency. There's the use of tracking devices on websites, spyware that links personal characteristics and personal browsing behaviours to other features. Our privacy protection rules are based on a notion of transparency, consent, and notification when information is being captured about you.
As I've said, there are very few rules that apply in the U.S. Those kinds of practices challenge the basic notion that underpins the kind of privacy protection rules that underpin PIPEDA in Canada, and which suggest that when information is collected about you, you know who is collecting that information, what information it is, and the purposes for which it's going to be used. You have a right to see that information and to correct it if it's inaccurate. You have a right to control to whom that information is communicated.
Those fair information principles underpin our federal and provincial and public and private sector laws in Canada.
It is the lack of transparency, to answer your question more directly, that I think is the most troubling.
