Madam Speaker, on the same point of order, my understanding is that it is entirely appropriate to say that what someone is saying is false. What is not permitted is to call somebody a liar in the House.
Madam Speaker, if you are not prepared to rule on this right now, perhaps you should reflect on that and come back at a later time. The comments the member from the Bloc brought up are extremely germane to this, and I would hate to see us rush into making a ruling right now without proper reflection because it is very important.
