When Canadian Forces returned to Kandahar, the Taliban began a major offensive. There were a record number of attacks against Canadian soldiers that spring, including six deaths.
Operation Mountain Thrust was launched in the beginning of summer 2006, in response to the gathering of Taliban forces in Kandahar and
Helmand provinces. Canadians of the 1 PPCLI Battle Group were one of the leading combatants and the first fighting when the
Battle of Panjwaii took place. Daily firefights, artillery bombardments, and allied airstrikes turned the tides of the battle in favour of the Canadians. After the operation concluded, Taliban fighters returned to the
Panjwai District in numbers that had not been seen before in a single area in the post-Anaconda war. The Canadian Forces came under NATO command at the end of July, and the 1 RCR Battle Group replaced the PPCLI. Canadians launched
Operation Medusa in September in an attempt to clear the areas of Taliban fighters from Panjwai. The fighting of Operation Medusa led to a second, fiercer Battle of Panjwai in which daily gun-battles, ambushes, and mortar and rocket attacks targeted the Canadian troops. An estimated 1,500 to 2,000 Taliban fighters were reluctant to give up the area, and after being surrounded by the Canadian Forces, they dug in and fought a conventional style battle. After weeks of fighting, the Taliban were cleared from the Panjwai area and Canadian reconstruction efforts began. On 15 September 2006, the Canadian government committed a
squadron of
Leopard C2 tanks from
Lord Strathcona's Horse and an additional 200 to 500 troops to Afghanistan. On 1 November 2006, Fraser stepped down as head of NATO Regional Command South, which was rotated to Dutch command. On 15 December 2006, the Canadians launched
Operation Falcon Summit into
Zhari District, to the north of Panjwai, as part of the NATO-led
Operation Mountain Fury. During Operation Falcon Summit, the Canadians gained control of several key villages and towns that were former Taliban havens, such as Howz-E Madad. During the first week of the operation, massive Canadian artillery and tank barrages were carried out in a successful attempt to clear pockets of Taliban resistance. The operation concluded with plans to build a new road linking Panjwai with
Kandahar's Highway 1 that runs east–west through Zhari. In February 2007, the 2 RCR Battle Group took over combat operations in several districts of Kandahar Province. From 15 July 2007 to February 2008, units from
CFB Valcartier near Quebec City served in Kandahar filling most positions in the
Operational Mentoring and Liaison Team (OMLT) and providing the protective company for the Provincial Reconstruction Team (PRT). The 3rd Battalion
Royal 22e Régiment Battle Group, with supporting troops from
5 Canadian Mechanized Brigade Group and a composite tank squadron from
Lord Strathcona's Horse conducted operations on the ground. This rotation reflected a change in tactics, with emphasis on systematically clearing, holding and building in the districts of
Panjwai and
Zhari, while also protecting
Arghandab District and the Afghan–Pakistan border in the area of
Spin Boldak. The focus was on intimately working with the Afghan army, police and civil administration to hold cleared areas rather than subsequently lose them to returning Taliban, as had previously occurred throughout the south and east. In February 2008, the
Van Doos contingent was replaced by a force centred on a
PPCLI battle group. Also in February, Canadian Major-General
Marc Lessard took command of Regional Command South for nine months. On 13 March 2008, the Harper Conservative government's motion to extend the military mission past February 2009 into 2011 was approved in a parliamentary vote with the support of the Liberal opposition. The extension of almost another three years had a focus on reconstruction and training of Afghan troops, and set a firm pullout date, calling for Canadian troops to leave Afghanistan by December 2011. While the Liberals voted in favour of the Conservatives' confidence motion, the
New Democratic Party and the
Bloc Québécois voted against it, having consistently rejected any extension of the military mission. NDP leader Jack Layton said "There are millions of Canadians who don't want this strategy to continue. The population prefers a road to peace." As part of the
new US administration's policy on Afghanistan, 17,000 new US troops were deployed to the country with a third stationed in Kandahar province. On 10 August 2009, Brig-Gen. Jonathan Vance of Task Force Kandahar transferred the authority of some of Kandahar Province to Col. Harry Tunnell IV, commander of the US Army's 5th
Stryker Brigade. Canadian troops were then stationed primarily around Kandahar City and the surrounding districts. ==2010–2011: US surge, combat ends==
