> The point being... _they then know where it's from_, that's the metadata. If they know the trade show, then they know where and when it was, whether it was in Canada and whether they need to delete it. In most cases they probably only know the URL, and it's far from trivial (or even possible in a general case) to mechanically derive if photo was taken in Canada from that. Personally I hope they're forced to overshoot and delete far more than necessary to ensure compliance (e.g. only keep photos they can positively determine were taken outside of Canada).
