General Walt Natynczyk, the chief of Canada's defense staff, speaks during a news conference at the Department of National Defence headquarters in Ottawa December 9, 2009. Natynczyk confirmed on Tuesday that the country's entire 2,800-strong military mission in Afghanistan would be withdrawn by the end of 2011, appearing to dash U.S. hopes that some of the troops might remain.
