摘要:In an effort to strengthen territorial claims in the Arctic, Prime Minister Stephen Harper announced on 10 August 2007 that Canada would build a deep-sea military port in Nanisivik, Nunavut. The port will enable the Royal Canadian Navy (RCN) to extend its operational range in the Arctic by enabling re-supply, refuel, and transfer of goods and personnel inside the eastern entrance of the Northwest Passage. Shortly thereafter, the federal government released the Canada First Defence Strategy (2008), and Canada’s Northern Strategy (2009), and committed to procuring Arctic Offshore Patrol Ships (AOPS) for the RCN to operate in northern waters.
