Results: Police now need a warrant to get a person's IP address, Supreme Court rules

The Supreme Court of Canada made a key privacy ruling last Friday that means police must now first have a warrant or court order to obtain the numbers making up a person or organization's IP address. The top court was asked to consider whether an IP address alone, without any of the personal information attached to it, was protected by an expectation of privacy under the Charter. In a five-four split decision, the court said a reasonable expectation of privacy is attached to the numbers making up a person's IP address, and just getting those numbers alone constitutes a search.
