I'll do my best. Critical infrastructure is not my direct responsibility, but in 2010 the Minister of Public Safety, together with his counterparts in the provinces, announced the national strategy for critical infrastructure. Essentially this is a plan to address threats to vital assets in systems, like financial systems, transport networks, electricity grids, and so on. It's more or less a vision for building public-private partnerships, improving information sharing among levels of government with the private sector on risks and threats, and conducting risk management activities and exercises.
The chief superintendent talked a bit about those kinds of exercises, but there are a number of working groups by sector, and those sectors roll up once a year into a national forum. They receive classified briefings on threats and risks, exchange information on building risk methodologies, and so on. There's also, in a sense, a counterpart to that of work with the United States, given how our critical infrastructure entwines with theirs to some degree.
