In other words, in your example, it's only incidentally that your conversation would be intercepted, because maybe you are talking with somebody else abroad, another entity, and CSE wants to target that other entity, not you. If you happen to be there, this is what we call “incidental”. While targeting foreign entities, CSE might intercept private communications involving Canadians incidentally. That's why they need an authorization from the minister to do that, okay? The prime target is not the Canadian; the prime target is the foreign entity.
