Troops would stay 'in some technical capacities'
The Tory government, supported by the Liberals, extended the military mission in Kandahar province to 2011 earlier this year, with a shift to emphasize the mission's priorities to reconstruction and development in the region.
Harper has made past statements in support of a shift in Canada's priorities in Afghanistan, but the prime minister's latest comments appear to show for the first time his acceptance of a troop pullout by the date.
"It's fair to say he was clearer and perhaps more forceful than before on what is going to happen in 2011," the CBC's Paul Hunter reported from the Harper campaign.
While there may be a few Canadian soldiers who stay on after 2011 as advisers, the bulk of the troops will be home by then, Harper said.
"I don't want to say we won't have a single troop there, because obviously we would aid in some technical capacities," he said.
