On March 26, 2025, the Global AI Risks Initiative at the Centre for International Governance Innovation and the Privy Council Office of Canada co-hosted a full-day, in-person scenarios workshop in Ottawa, Ontario, to explore existing and emerging implications for national security posed by next-generation artificial intelligence (AI) systems. This summary report contains policy recommendations that are intended to stimulate and enrich discussion among policy makers and the broader public. It is composed of three parts: an executive summary highlighting key messages drawn from the workshop discussions and background literature; a detailed description of key uncertainties and five possible future AI scenarios and implications considered at the workshop, adapted from the background paper shared with participants in advance of the workshop; and an appendix summarizing key points from the workshop discussion.
