Prorogation is the formal ending of a parliamentary session, occurring when the Prime Minister advises the Governor General to prorogue Parliament. Unlike dissolution, which ends a Parliament entirely and triggers an election, prorogation simply ends the current session while keeping the same Parliament. When Parliament is prorogued, all committee work stops, bills that haven't passed die (though they can be reintroduced), but Parliament remains constituted. A new session begins with a Speech from the Throne outlining the government's agenda. Prorogation has sometimes been controversial when used to avoid votes of non-confidence or to shut down parliamentary inquiries.
