On 22 October 2014, a gunman, armed with a rifle, shot at the sentries on duty at the tomb, fatally wounding one, Corporal Nathan Cirillo of The Argyll and Sutherland Highlanders of Canada (Princess Louise's), before proceeding across the street and into the Centre Block parliament building. There, the gunman was killed in a firefight inside the building. Cirillo (and Warrant Officer Patrice Vincent) was mentioned by Governor General David Johnston in his speech at the Remembrance Day ceremony of that same year, when the Governor General and Anne, Princess Royal (who brought a message from Queen Elizabeth II), re-dedicated the monument once again. A plaque commemorating Corporal Cirillo's service at the War Memorial was dedicated at the site.
