I think whenever we hear about this regressive rolling back of privacy protections that were hard fought for, of course there is concern.
It's not clear to me the degree of risk that Canadians face, but the reality is that our online lives are not constrained by borders. We deal with U.S. companies, and we browse sites owned by U.S. companies. I don't know for sure, but my speculation would be that we should be concerned, because our information is bound to be caught up in exactly the same net that American information is going to be caught up in, in that there is no regulation about not sharing this kind of information.
Where there is some level of protection in Canada, obviously when we're talking about a law referring to ISPs, is that most of us probably have subscriptions with a Canadian service provider here in Canada, but then many of these telecommunications companies have global reach and are networked together in ways, some of which we know and some of which, as ordinary citizens, many of us don't. But, again, that would put information at risk potentially through those kinds of connections.
