Canada is withdrawing from a NATO project that would allow the Alliance to monitor weapons of mass destruction, civil unrest and evacuation operations, CBC News reported. Canada joined 13 other countries in signing a memorandum of understanding in 2009 on the Alliance Ground Surveillance project. Canada would have had to pay $450 million over 20 years. Through the project, NATO would perform surveillance using unmanned aerial vehicles. The government said the details of its withdrawal are still under discussion with NATO.
