Good Samaritan laws are laws or acts protecting those who choose to serve and tend to others who are injured or ill. They are intended to reduce bystanders' hesitation to assist, for fear of being sued or prosecuted for unintentional injury or wrongful death. In Canada, a good Samaritan doctrine is a legal principle that prevents a rescuer who has voluntarily helped a victim in distress from being successfully sued for 'wrongdoing'. Its purpose is to keep people from being reluctant to help a stranger in need for fear of legal repercussions should they make some mistake in treatment.[1] Good Samaritan laws vary from jurisdiction to jurisdiction, as do their interactions with various other legal principles, such as consent, parental rights and the right to refuse treatment. Such laws generally do not apply to medical professionals' or career emergency responders' on-the-job conduct, but some extend protection to professional rescuers when they are acting in a volunteer capacity.
