• Police need a warrant, but websites and regular businesses can collect and link a user’s IP to their personal details and share it with anyone, with no court intervention required.

    How does that make any sense?

    Maybe police will find a way around this loophole by purchasing collected data as an “advertising partner.”

  • I’m glad the decision swung in favour of Charter protection. I worry about the implications in terms of IPv6. Typically, addresses in that case are built out of the MAC address of the device. That means you can nail down not just the person but the exact device they were using. Since IPv6 is big in the cellular world, that means your phone.

      • Well that’s not really what I’m referring to. I’m talking about EUI-64, which was supposed to make life easier by giving everyone an IP addressed based on their MAC address. You wouldn’t need to worry about address collisions with such an address, as it would be globally unique.

        But following up on it a little just now, it seems the idea is falling out of favour precisely due to the privacy issues I was fretting about. I assume that means DHCP or some similar scheme will come to dominate just as with IPv4? I’m not an IT guy so I don’t know what the current thinking is on this.

  • This is the best summary I could come up with:


    Writing for the majority, Justice Andromache Karakatsanis wrote that an IP address is “the crucial link between an internet user and their online activity.”

    “Thus, the subject matter of this search was the information these IP addresses could reveal about specific internet users including, ultimately, their identity.”

    Writing for the four dissenting judges, Justice Suzanne Côté disagreed with that central point, saying there should be no expectation of privacy around an IP address alone.

    The court’s decision is based on the case of Andrei Bykovets, who was convicted of 14 online fraud for purchases from an Alberta liquor store.

    In 2017, the Calgary Police Service investigating the alleged crime discovered that the store’s online sales were managed by Moneris, a third-party payment processing company.

    At trial, Bykovets argued that he was the victim of an unreasonable search and seizure, a violation of Section 8 of the Charter of Rights and Freedoms, because he had an expectation of privacy with respect to his IP address.

  • An IP address is basically public information when you do anything online. Why would police need a warrant to obtain it? Do they need a warrant to look at a phone book and find your street address? Why is this any different? Besides, hiding your identity online is one of the first things a hacker learns. This whole thing makes no sense and proves how out of touch some of these people are.
