The cyber-policy issue for the Government of Canada runs out of Public Safety. That's something they've been working on for a long while and that we and others are plugged into.
As you note, by its nature, cyberspace is very much a shared space, and obviously in North America in particular there are a number of interlinkages. I couldn't tell you, frankly, to what extent which areas might be more vulnerable or which ones are more.... I wouldn't want to get into that anyway, even if I did have the information at my fingertips, but certainly it is something that we work very closely on with the Americans, on the military side with U.S. cyber command, and with our own elements within the Department of National Defence.
Given the nature of it and the interlinkages not just military to military but between government and the private sector and then private sector to private sector, it really is something that has to be addressed holistically, which is why Public Safety might be in a better position to comment on some of those things.
