In Canada, do you even really have a right to privacy when in public spaces like a shopping mall? Is there even a legal expectation that there aren't cameras doing this kind of thing all the time? In most places in the US I know there isn't a right to privacy within a public space. If I as a shop owner put up security cameras in this same fashion in most of the US this wouldn't be against the law. There's no law preventing me from putting up cameras all along my home looking out into the street doing the same.
