On June 27 and 28, 2023, the Centre for International Governance Innovation (CIGI) hosted the Waterloo Security Dialogue (WSD). The conference brought together leaders and experts to establish connections across jurisdictions with the objective of improving cybersecurity information sharing and incident response in ways that will contribute to a stronger national culture of cybersecurity resilience. The conference revolved around three key themes: cyberthreat information sharing; cyber incident collaboration and coordination practices; and initiatives to enhance cyber resilience in Canada. These themes were explored through engaging panel discussions, keynote presentations and interactive sessions. This report presents key takeaways from the conference discussions. It does not aim to present a unanimous consensus among participants or reflect the views of any specific individual or organization. Rather, its primary objective is to lay out key challenges and ideas identified by participants — these will be explored further through CIGI-led workshops and subsequent WSDs.
