OTTAWA—CSIS rarely says a lot openly about what it knows: when it does it should be listened to. Canadians could be said to have a love-hate relationship with the Canadian Security Intelligence Service (CSIS). Wait, scratch that. A few Canadians seem to have a love-hate relationship with CSIS. On the one half, there are those who think our spy agency is the spawn of Satan populated with knuckle-dragging, sloped-forehead simian life forms who love to see threats where there are none. On the other, there are the (obviously smarter) ones who recognize what CSIS does for us. I am not surprisingly squarely in the latter camp.
