Canada's role in the Afghanistan War began in late 2001. Canada sent its first element of soldiers secretly in October 2001 from Joint Task Force 2, and the first contingents of regular Canadian troops arrived in Afghanistan in January–February 2002. Canada took on a larger role during the Afghan conflict starting in 2006 after the Canadian troops were redeployed to Kandahar province. 2,500 Canadian Forces (CF) personnel were in Afghanistan and 1,200 made up the combat battle group. At the 2012 NATO Summit in Chicago, Prime Minister Stephen Harper announced that an undisclosed number of Canadian soldiers would remain in the country to help train and mentor the Afghan National Army until 12 March 2014.
