If I can have members' attention, it is a very serious item and each and every member does take an oath. However, we do have a precedent set here on page 209, chapter 4 of the 3rd edition of Bosc and Gagnon. Let me quote it.
...the Speaker was asked in 1990 to rule on the sincerity of a Member’s solemn affirmation. Speaker Fraser ruled that the Chair was “not empowered to make a judgement on the circumstances or the sincerity with which a duly-elected Member takes the oath of allegiance. The significance of the oath to each Member is a matter of conscience and so it must remain”.
