I'd be entirely speculating about the motives of somebody we don't know the identity of as to why he or she leaked.... I don't think it would be responsible to speculate on that. It can be accidental. It can be deliberate. There can be any number of motivations.
I think what I would be concerned about is the end effect of that, which is that it's done damage to CSIS's reputation with our Five Eyes partners. They will now think of it as a less secure institution, and that's permanent damage. If the Americans and the Brits start to withhold documents from us—“let's not send them to the Canadians”—we'll never know.
