Every year more than 40,000 children go missing in Canada. Less than one per cent are broadcast through AMBER Alerts due to its specific criteria and high threshold. With GIS and technology, Missing Children Society of Canada (MCSC) created a search network connecting police and the community in real-time when kids go missing. Amanda Pick, CEO of MCSC talks to Guan about the mobile app MCSC rescu (rescu.mcsc.ca) and its story in bringing home two missing children.
