The Waterloo Security Dialogue delved into Canada’s national cyber resilience by exploring the interconnectedness of cybersecurity among various levels of government (federal, territorial, provincial, municipal), Indigenous groups and the private sector. The conversations centred around three key themes: the sharing of cyberthreat information and the factors contributing to its effectiveness; collaboration and coordination practices during cyber incidents between government agencies and the private sector; and initiatives aimed at bolstering cyber resilience in Canada. The primary goal was to identify existing challenges and collectively determine the most helpful strategies for long-term effectiveness, thereby paving the way for enhanced cybersecurity measures and future collaborative efforts. The dialogue consisted of scenario-based sessions and expert panels led by specialists from Canada, the United Kingdom, the United States and other jurisdictions. Key federal leads for national cybersecurity, cybercrime, cybersecurity in Canadian industry, national security and emergencies were present.
