Not sure about other places in Canada or the US, but here in Manitoba its the law. It falls under the personal privacy protection statutes.
Every place that you go into that has a camera has a sign or sticker at every door saying that you are being recorded. Only exceptions are public areas like malls and office common hallways.
Some signs go into detail saying what the images would be used for, others don't.
