Ms. Normandin, You've just raised a very important question.
I wrote an entire book about that, called Intelligence as Democratic Statecraft, which has a chapter on exactly how Canada operates, and the positive and negative aspects of the existing system.
In Canada, the sharing of information is definitely a problem. As I point out in my book, we need to place more trust in our parliamentarians. They know precisely how to use the intelligence and information available to them. They are in a very good position to decide what should be done with the information and how to communicate their conclusions to the general public.
I understand the reluctance about the structure of the committee on the one hand, and the sharing of intelligence on the other. However, the evidence obtained from other parliamentary partners, like the United Kingdom and Australia, would not lead to the current government's conclusion that you can't really trust parliamentarians. The very opposite is the case.
