The scope and extent of an investigator's powers are largely undetermined, although cases dealing with nuisance and trespass provide some guidance. The 1982 decision in Saccone v. Orr recognized a generalized tort of invasion of privacy, as has other legislation in four provinces. However, existing Canadian case law does not provide clear guidance regarding appropriate behavior by investigators. Thus, investigators should rely on their positions as agents and on their clients' accurate assessments of their legitimate interest in a subject. In addition, relying on their voluntary professional standards of ethics could be a more effective approach than legislation as a means of balancing the rights and interests of clients and the right to privacy of those who may become the subject of such investigations. However, a statutorily created disciplinary body that could advise on penalties for ethics violations might also provide a mechanism flexible enough to balance these interests. 230 footnotes.
