The Canadian Centre for Cyber Security is in fact one of many such national centres. We work very closely with similar centres and the Five Eyes, but also with centres around the world. Part of the centre also is the national CERT, the national element that does emergency response teams, which is part of a global network. You have layers of cybersecurity practitioners working together and sharing—where they can—information that's relevant for their mandates.
