It was really a question.
I will read it for the record, if you'd like: “The Act states: 'Every Member of the...House of Commons'”—and I assume the Senate would have something similar —“'shall before taking his [or her] Seat therein take and subscribe before the Governor General or some Person authorized by him [or her]...the Oath of Allegiance'”, which is “I...do swear, that I will be faithful and bear true Allegiance to Her Majesty Queen Elizabeth the Second”, or a similar oath.
They would have taken that oath.
