How have courts distinguished privacy interests under s. 8 of the Charter?

Canadian courts have distinguished a number of privacy interests protected by s. 8 of the Charter, including territorial privacy, privacy of the person, and informational privacy: R v. Tessling, as above. In any given case these protected privacy interests may overlap. That said, not all conceivable privacy interests are afforded constitutional security. The s. 8 guarantee against unreasonable search and seizure protects only reasonable expectations of privacy: Hunter v. Southam Inc., 1984 CanLII 33 (SCC), [1984] 2 S.C.R. 145, at page 159.
