"References to harassing a person include alarming the person or causing the person distress. "
"Subsection (1) does not apply to a course of conduct if the person who pursued it shows - (a) that it was pursued for the purpose of preventing or detecting crime, (b) that it was pursued under any enactment or rule of law or to comply with any condition or requirement imposed by any person under any enactment, or (c) that in the particular circumstances the pursuit of the course of conduct was reasonable"
"... It will be a defence to show that the conduct was pursued for the prevention and detection of crime, or under an enactment or rule of law. Because of the nature of the activities pursued by stalkers, unless special provision is made, some police activities could be caught by the Bill. That, of course, is not our intention. I am also aware that the activities of journalists, salesmen, religious activists, debt collectors, private investigators and even political canvassers might fall within the scope of the Bill. We have therefore provided a defence of acting reasonably in the particular circumstances of the case in order to safeguard these legitimate activities. "
