When Parliament "shuts down," one of three very different things has happened. Adjournment is a scheduled break — nothing dies. Prorogation ends the session — government bills die on the Order Paper. Dissolution ends the Parliament itself — everything dies and an election follows. Each has been used strategically, and knowing which is which is the difference between a holiday and a constitutional event.
Parliament stops sitting in three legally distinct ways. Adjournment suspends sittings within a session — committees can keep working and all business survives. Prorogation, exercised by the Governor General on the Prime Minister's advice, terminates the session: government bills die on the Order Paper (they can be reinstated by motion in a new session at the stage they had reached), while private members' business carries over automatically under the Standing Orders. Dissolution, also on the Prime Minister's advice, terminates the Parliament entirely and triggers a general election; every bill dies with no reinstatement. Prorogation has repeatedly been used at politically convenient moments — Stephen Harper in December 2008 during the coalition crisis, Justin Trudeau in August 2020 during the WE Charity committee studies, and again in January 2025 during the Liberal leadership transition — making the mechanism itself a recurring accountability question.
Adjournment is the House of Commons taking a scheduled break within a session — evenings, weekends, the summer recess, the winter break. The House adjourns itself under its own calendar and Standing Orders; no role for the Governor General, no constitutional event.
The defining feature: **nothing dies.** Every bill stays exactly where it is on the Order Paper. Committees can continue meeting, studying, and hearing witnesses while the House itself is adjourned. Written questions remain on the Order Paper awaiting answers.
When commentators say "Parliament has risen for the summer," that is adjournment. The machinery is idling, not off.
Prorogation terminates a **session** of Parliament. It is exercised by the Governor General on the Prime Minister's advice — in practice, a phone call or a meeting, followed by a proclamation.
What happens on prorogation:
- **Government bills die on the Order Paper.** A bill at committee stage, report stage, or awaiting third reading is gone. - **Committees cease to exist** for the session. Every study, every witness list, every draft report ends. - **Written questions are wiped** from the Order Paper. - **Parliament returns with a new Speech from the Throne**, opening a new session.
Two important survival mechanisms soften this. First, a new session can pass a **reinstatement motion** restoring government bills to the stage they had already reached — but the government must propose it and spend House time on it. Second, **private members' business survives automatically** under Standing Order 86.1; a backbencher's bill resumes where it left off.
The asymmetry is the point worth noticing: the government's own bills can be revived at the government's initiative, and committee investigations — the thing prorogation kills most thoroughly — have no reinstatement mechanism at all. A new committee must start the study again from scratch.
Dissolution terminates the **Parliament itself**. Every seat in the House of Commons is vacated, a general election follows, and the next Parliament starts from zero.
Everything dies — government bills, private members' bills, committee studies — and nothing can be reinstated, because the body that was considering them no longer exists. A bill that died at third reading on dissolution must be reintroduced at first reading in the next Parliament and travel the whole road again.
Dissolution happens on the Prime Minister's advice to the Governor General, subject to Canada's fixed-election-date law — which sets a default election date but, as its own text and practice confirm, does not prevent an earlier dissolution. Like prorogation, the GG's acceptance of the advice is governed by convention, with reserve-power refusal a theoretical backstop (the 1926 King-Byng affair being the canonical — and only — federal example, covered in our Governor General explainer).
Three modern prorogations made the mechanism famous, and they span both major parties:
- **December 2008 — Stephen Harper.** Weeks after the election, facing a Liberal-NDP coalition agreement (with Bloc support) ready to defeat his government on a confidence vote, Harper asked Governor General Michaëlle Jean to prorogue. She granted it after a meeting of more than two hours. By the time Parliament returned in late January, the coalition had collapsed. - **August 2020 — Justin Trudeau.** With four committees studying the WE Charity affair, Trudeau prorogued Parliament until late September. The studies died with the session. - **January 2025 — Justin Trudeau.** Announced alongside his resignation as Liberal leader, proroguing Parliament until March 24, 2025, while the party selected a successor — pausing, among other things, a House deadlocked over a document-production fight.
In each case the government described the prorogation as routine and necessary; in each case the opposition described it as escaping scrutiny. Both descriptions fit the record — which is precisely why the mechanism deserves to be understood rather than taken on either side's framing.
Parliament Audit's practice: when a prorogation lands, we report what dies on the Order Paper, item by item. The list speaks for itself.
Most Canadians know the Senate exists. Few know that almost every government bill gets amendments proposed there, and that the proportion of those amendments that survive is tiny. This article walks how the Senate amendment process actually works, why the success rate is low, and the rare cases when Senate amendments have changed the law.
In 1998 the Supreme Court of Canada was asked: can a province secede unilaterally? Their answer became the legal framework that governs every secession question in Canadian constitutional law. This article walks the ruling, what it actually says, and why it applies to Alberta in 2026 just as much as it applied to Quebec in 1998.
Section 33 of the Charter of Rights and Freedoms — the "notwithstanding clause" — lets Parliament or a provincial legislature override certain Charter rights for five years at a time. It is one of the most-debated and most-misunderstood features of the Canadian Constitution. This article explains exactly what it does, what rights it can and cannot override, when it has been used, and why it exists.

<h1>Prorogation, Dissolution, Adjournment: Three Ways Parliament Stops Sitting, and Why the Difference Matters.</h1>
<p><em>By Parliament Audit · June 11, 2026 · 5 min read</em></p>
<p><strong>Parliament stops sitting in three legally distinct ways. Adjournment suspends sittings within a session — committees can keep working and all business survives. Prorogation, exercised by the Governor General on the Prime Minister's advice, terminates the session: government bills die on the Order Paper (they can be reinstated by motion in a new session at the stage they had reached), while private members' business carries over automatically under the Standing Orders. Dissolution, also on the Prime Minister's advice, terminates the Parliament entirely and triggers a general election; every bill dies with no reinstatement. Prorogation has repeatedly been used at politically convenient moments — Stephen Harper in December 2008 during the coalition crisis, Justin Trudeau in August 2020 during the WE Charity committee studies, and again in January 2025 during the Liberal leadership transition — making the mechanism itself a recurring accountability question.</strong></p>
<h2>Adjournment: the pause button</h2>
<p>Adjournment is the House of Commons taking a scheduled break within a session — evenings, weekends, the summer recess, the winter break. The House adjourns itself under its own calendar and Standing Orders; no role for the Governor General, no constitutional event.</p>
<p>The defining feature: **nothing dies.** Every bill stays exactly where it is on the Order Paper. Committees can continue meeting, studying, and hearing witnesses while the House itself is adjourned. Written questions remain on the Order Paper awaiting answers.</p>
<p>When commentators say "Parliament has risen for the summer," that is adjournment. The machinery is idling, not off.</p>
<h2>Prorogation: the reset button</h2>
<p>Prorogation terminates a **session** of Parliament. It is exercised by the Governor General on the Prime Minister's advice — in practice, a phone call or a meeting, followed by a proclamation.</p>
<p>What happens on prorogation:</p>
<p>- **Government bills die on the Order Paper.** A bill at committee stage, report stage, or awaiting third reading is gone.

<h2>Dissolution: the off switch</h2>
<p>Dissolution terminates the **Parliament itself**. Every seat in the House of Commons is vacated, a general election follows, and the next Parliament starts from zero.</p>
<p>Everything dies — government bills, private members' bills, committee studies — and nothing can be reinstated, because the body that was considering them no longer exists. A bill that died at third reading on dissolution must be reintroduced at first reading in the next Parliament and travel the whole road again.</p>
