The Supreme Court has also held that a hospital patient
undergoing treatment for injuries sustained in an automobile accident has a relatively big expectation of privacy; in other words, a reasonable expectation that the results of a
blood analysis undertaken for medical reasons will not be shared with non-medical personnel without his or her consent: R. v. Pohoretsky, [1987] 1 S.C.R. 945; R. v. Dyment, [1988] 2 S.C.R. 417; R. v. Dersch, [1993] S.C.R. 768; R. v. Borden, [1994] 3 S.C.R. 145.
