Procedural Notes




A Parliament, which begins after a general election and ends when the next election is called, is comprised of one or more sessions. A session begins with a Speech from the Throne and ends with prorogation or dissolution. Prorogation ends a session and is usually followed by the opening of a new session of the same Parliament, whereas dissolution marks the end of both the final session and the Parliament, and is followed by a general election. Both prorogation and dissolution have effects on the business of the Senate and its committees.

Procedure For Prorogation and Dissolution

Prorogation and dissolution are not decisions made by Parliament, but rather prerogative acts of the Crown done on the advice of the Prime Minister.

Typically, prorogation is announced by a proclamation of the Governor General while the houses are not sitting. This formal announcement specifies the date until which Parliament is prorogued. This date can be brought forward or postponed by a subsequent proclamation on the advice of the cabinet, as long as the constitutional requirement that Parliament assemble at least once every 12 months[i] is met. Although this has not been done since 1983, prorogation may also be announced in the Senate Chamber if the Senate is then sitting.

Dissolution marks the end of a Parliament and triggers a general election. Under the Constitution, the maximum duration of a Parliament is five years[ii]. However, since 2007, the Canada Elections Act provides that a general election must be held on the third Monday of October in the fourth calendar year following polling day for the last general election, unless there is a prior dissolution of Parliament or the Chief Electoral Officer recommends an alternative date[iii].

Typically, dissolution occurs when the Prime Minister recommends to the Governor General that Parliament be dissolved and the Governor General issues a proclamation to that effect. The Prime Minister also requests the issuance of writs of election from the Chief Electoral Officer, and the Governor General issues a proclamation for the issuance of these writs of election. In addition to these two proclamations, a third is issued at the same time to summon the new Parliament on a specified date. As with prorogation, this date can be brought forward or postponed by a subsequent proclamation.

Effects of Prorogation and Dissolution


Prorogation and dissolution have no effect on senators’ terms of office. However, the Senate cannot meet during a period of prorogation or dissolution.

Speaker and Speaker Pro Tempore

The Speaker of the Senate remains in position while still a senator[iv], until a new Speaker is named, irrespective of prorogation or dissolution.

The Speaker pro tempore is nominated for the session and therefore ceases to hold that position during prorogation or dissolution.

Senate Business

All business before the Senate (i.e., bills, reports, motions, inquiries, etc.) is terminated as of prorogation or dissolution. If a senator wishes to have an item studied again by the Senate in a new session, the item must be reintroduced, and the process starts anew.


Upon dissolution or prorogation, all standing, special and joint committees cease to exist, and the chairs and deputy chairs cease to hold office, with the exception of the Standing Committee on Internal Economy, Budgets and Administration, which continues until members are named to the committee in the next session[v]. This exception stems from provisions in the Parliament of Canada Act that give this committee certain powers to continue to manage the internal business of the Senate.

Senators who are members of the Standing Committee on Ethics and Conflict of Interest for Senators at the time of prorogation or dissolution form an Intersessional Authority of Ethics and Conflict of Interest for Senators, which can continue some of the work of the committee until members are appointed to the committee in the new session[vi]. In addition, pursuant to a decision of the Senate on June 8, 2021, the senators who were members of the Standing Committee on Audit and Oversight at the end of the Second Session of the Forty-third Parliament formed an Intersessional Authority on Audit and Oversight at the end of that session[vii].

As is the case with all Senate business, committee-related business, except as outlined previously, is terminated at prorogation or dissolution. Orders of reference that were adopted by the Senate during the session expire, as do committee budgets. If a committee is unable to table or present a report to the Senate before prorogation or dissolution, but wishes to do so in a new session, it must first obtain a new order of reference for the study. Normally, a motion for a new order of reference will include an order referring the work conducted on the study in a previous session (or sessions) back to the committee, so the committee does not need to redo the work it has already completed. However, the committee must adopt the report again before it can table or present it in the Senate. It should be noted that a committee could decide to hold additional meetings in the new session to hear additional witnesses or to revise the report.

Prorogation or dissolution also ends the government’s obligation to table a response to a committee report in the Senate. If the committee or an individual senator wishes to request a government response to a committee report tabled in an earlier session, this can be done by way of a motion in the Senate[viii].

Parliamentary Associations and Interparliamentary Groups

Senators who are association members remain in their positions during prorogation or dissolution.

Senate Administration

As a permanent body of the Senate, the Senate Administration continues to function without interruption during a period of prorogation or dissolution.
