On October 22 , 2014 , during the Parliament Hill attack , Vickers was initially identified as the sole hero and credited with the fatal shooting of Michael Zehaf-Bibeau , but once the independent OPP report was released on June 1 , 2015 , it was revealed that the suspect was shot several times by both Vickers and RCMP Constable Curtis Barrett . Zehaf-Bibeau entered the Centre Block under the Peace Tower , shooting a Commons security guard in the leg , exchanging gunfire , before running down the Hall of Honour to an alcove by the entrance to the Library of Parliament , which is beside Vickers ' office . Vickers pulled a 9 mm handgun from a lock-box and entered the hall . He stood behind the pillar in an opposite position to Zehaf-Bibeau and shortly after Zehaf-Bibeau had pulled away from the pillar and shot at Barrett , Vickers threw himself on the ground and fired multiple shots at the gunman , effectively debilitating him . A niece told the '' Calgary Sun '' , " This is the first time in his career that he 's shot anyone . " Vickers officially started duties as the Canadian ambassador to Ireland on 21 January 2015 , replacing Loyola Hearn
