May I add a bit, Mr. Chair?
Under the Canadian Constitution traditionally, foreign policy was the exclusive or sole responsibility of the Governor in Council, which meant the Prime Minister and cabinet in practice. What has changed recently as a result of a campaign commitment of the new Conservative government is a step to further consultation with Parliament on matters that traditionally were left solely for the cabinet.
For example, we had a vote to consider changes to and continuation of the NORAD treaty--the defence of North America, the treaty with the United States. Traditionally the way that would have been done is cabinet would have considered it, and after the treaty was negotiated, it would have been ratified by cabinet. We have inserted an additional step in which there was a debate in Parliament and a vote on that and then the ultimate cabinet ratification.
Similarly, on a decision on extending our involvement of our military in Afghanistan, when those troops were sent originally, the normal historic constitutional practice of the decision being made by the Prime Minister and cabinet was followed. This time we went to Parliament and sought its approval for extending that commitment.
So there is a bit of an evolution happening here. Does it have legal force and consequence, or is it just the practice of this Parliament? I would say right now it's just the practice of this Parliament, but as time evolves, if it continues and is practised continually, it might adopt the status of maybe a convention that is an accepted practice.
I hope that doesn't take away from question time, but helps answer the question.
