The Canadian Ambulance Service, Paramedicine and EMS Research Repository (CASPERR) was developed as a pan-Canadian open-access digital repository infrastructure. CASPERR will archive peer-reviewed journal articles, professional articles, theses, policy reports, conference presentations, posters, data sets, educational materials, and other forms of related research and knowledge products. It will be searchable, citable, and compliant with key Canadian and international open science policies.The mission of CASPERR is to support open science in paramedicine within Canada, providing a trusted and comprehensive space for researchers, policymakers, and others to share their data and outputs. CASPERR simplifies the process of complying with open science requirements, ensuring that research outputs are freely accessible, thereby accelerating scientific discovery and innovation within the discipline in Canada and beyond.
