I have, perhaps, a few thoughts on this. The mere fact that the committee is studying prorogation as per the changes in the Standing Orders is novel and represents what, over time, might be a change to the convention.
I would say that the convention is a very long-standing one. It predates Confederation. For the history wonks among us, it goes back to 1530. It is a long-established convention. It has been an established Canadian convention since 1867, and foundational for that convention is that the PM has the prerogative. It often takes place—I'm willing to say always takes place—in a very political context because it's a political move. That's never going to change.
I do think that the standing committee's work is actually a very interesting way of bringing light and sunshine to the decision, so I thank the committee for its work.
