On October 22, 2014, Michael Zehaf-Bibeau evaded security and entered the Hall of Honour with a rifle and a knife after fatally shooting Corporal Nathan Cirillo of The Argyll and Sutherland Highlanders of Canada (Princess Louise's), injuring a constable. On November 2014, the Joint Advisory Working Group on Security identified lack of communication among security groups at Parliament Hill as a significant problem, and recommended combining the existing security forces under the Senate, the House of Commons and RCMP detachment in charge of the grounds into one integrated security service. Parliament subsequently passed Bill C-59, which mandated this change.
