A parliamentary session is the period during which Parliament meets and conducts business, beginning with a Speech from the Throne and ending when Parliament is prorogued (suspended) or dissolved (ending for an election). Sessions can last months or years. Within a session, Parliament has sitting periods when the House meets and breaks when it recesses. A Parliament can have multiple sessions—each session starts fresh with a new throne speech and resets the legislative agenda. Bills that haven't passed when a session ends typically die, though procedures exist to restore some bills. Session lengths vary based on government needs and political circumstances.
