When Does an Elected Candidate Become an MP?

This is a follow-up to the post of October 21, 2015 entitled Library of Parliament Article on Opening of Next Parliament.

In July, the Library of Parliament updated a publication that explains When Does an Elected Candidate Become a Member of the House of Commons?:

"It is not entirely clear at what precise moment a successful candidate in a federal election technically becomes a member of the House of Commons. Among the dates used to mark this transition, the most important are:

• polling day/election day;
• the day the election writ is returned to the Chief Electoral Officer;
• the day the Chief Electoral Officer sends a certified list of members to the Clerk of the House of Commons;
• the day the member takes the oath of office; and
• the day the member takes his or her seat."

"This paper will examine arguments for and against each of these as the date on which a duly elected person should be considered a member of the House of Commons."
