Black Rod has the door slammed in his face, 2009 : Articles & Resources
Canada's parliamentary system is modelled in history after the British system. See the ceremony of the Black Rod in this video of UK state opening, 2009.
This video includes the door of the House of Commons being slammed on the face of Black Rod (the Queen's representative) to symbolise the independence of the elected House of Commons from the monarchy. This ritual is derived from what happened when the attempt by Charles I to arrest five MPs in 1642, in what was seen as a breach of privilege. After that incident, the House of Commons has maintained its right to question the right of the monarch's representative to enter their chamber, though they can not bar him from entering with lawful authority.
