Mr. Speaker, in our rules of order and decorum, they refer to Standing Order 18 and say, "Remarks...which question that Member’s integrity, honesty or character are not in order.”
During questioning of the Minister of Canadian Heritage, on a number of occasions it was referred to him as misleading the House. When someone accuses someone else of misleading the House, it certainly, at least in my opinion, would suggest that their integrity and indeed their honesty are being questioned in that regard.
I do not think it is necessary at this point to call out those members who were doing that, but it might be beneficial for you to remind members of that particular Standing Order 18 so that we can perhaps correct this moving forward.
