Maybe I will start, and Mike can weigh in.
On critical infrastructure, such as water systems and so on, there is a plan, a critical infrastructure plan, for Canada. You're seeing only half of the national security branch from Public Safety. The other components are cyber security and critical infrastructure. There's quite a detailed plan at the federal level for working with the provinces to protect critical infrastructure. There are also, in the Beyond the Border agreement, arrangements and agreements to work more with the U.S. on that issue.
On the issue of aviation security, Public Safety, my group in particular, leads the passenger protect program. We have a big role in this area of aviation security, obviously with the Department of Transport, which is more the front-line operator in managing security.
It's hard to write everything in one strategy. A lot of these specific things cascade down. We could talk afterwards.
