Good. If a court can criminally charge an entity based on the activity coming from their IP address, clearly it’s considered an identifying piece of information - almost like a virtual SIN or ID card. So my opinion is that in the same way there are restrictions on who you are compelled to give your SIN to, there should be limits here as well. There are, of course, going to be times when authorities legitimately require that information to pursue an investigation/prosecution but they should have to prove that need.
