Unknown and Young Adult Cases

Every year in Canada, there is a significant number of missing person reports made to police involving children and youth (under 18), and young adults (18–25), and there is sometimes no known explanation for their disappearance. If a child or young adult goes missing for no explainable reason (there is nothing to suggest they have been abducted or have run away), their disappearance may be described as an unknown case.*
