The Senate Speaker is appointed by the governor general on the advice of the prime minister, usually for the life of the Parliament. It is unusual for a Speaker to serve for more than one Parliament, though this has occurred a few times over the last 40 years. 

In the early days of Confederation, the Speaker was considered an important ally of the prime minister in the Upper Chamber. This has changed over time: Senate Speakers have become less partisan and more impartial in fulfilling their responsibilities as presiding officers.

Senate Speakers in the recent past have not attended the weekly Senate caucus meeting of their given party.  This is an example of how the modern-day speakership has moved towards a more neutral role. This Speaker, however, retains the right to vote and speak from his or her designated place in the Senate.
