In fact, that's a huge question, and it's exactly what the declassification project has been working on for the last couple of years.
I think there needs to be, at the first instance, a much clearer idea within government of what is actually sensitive and what isn't. Right now there is really no guidance within the Canadian government on the classification process, which is different from our allies.
In the American situation, there are manuals of a couple of hundred pages saying what is sensitive and how it should be classified. That doesn't exist in Canada.
