Canada continues to assert its military presence in its northernmost boundaries. Operation Nunalivut which ran in the Arctic from April 6-26, is one of three sovereignty exercises conducted each year by Canadian Forces (CF). This year’s joint maneuvers included, “the first landing and takeoff of an Air Force CC-177 Globemaster III aircraft at CFS Alert, from a gravel and ice covered airfield and the first CF dive in the high Arctic, which was the longest sustained ice dive operation in CF history. In addition, the Arctic Response Company Group conducted concurrent training with the Canadian Rangers for the first time in the Arctic, while a team of nine Regular and Reserve Force Signallers tested a new series of Iridium, high frequency and satellite communication systems.” As part of ongoing efforts by Canada-Denmark to strengthen diplomatic and security relations in the Arctic, the operation featured, “combined training with the Danish military’s SIRIUS Dog Sledge patrol.” An agreement reached between Russia and Norway over the long-disputed area in the Barents Sea has also prompted Canada to take steps to resolve conflicting Arctic offshore boundary claims with Denmark and the United States.
In May, Canada and Denmark signed a Memorandum of Understanding that will deepen defence and security cooperation in the Arctic, “through enhanced consultation, information exchange, visits, and exercises.” The annual joint Canadian Forces Operation Nanook will take place in the high Arctic from August 6-28. It is significant as it will include ships from the Danish and American navies, as well as the U.S. Coast Guard. Canada also recently announced measures designed to further protect and defend its northern sovereignty. “Beginning July 1, the Government of Canada is requiring that foreign and domestic vessels of a certain size report to the Canadian Coast Guard if travelling through Canada’s Arctic waters. This new mandatory requirement will ensure vessels report information such as identity, position and destination to the Canadian Coast Guard.” There has been much contention over the Northwest Passage. Canada maintains that it is an internal waterway and thus falls under its control, but the U.S. argues that it is an international strait. There are calls for the U.S and Canada to essentially suspend their disagreement over the northern sea route and assume joint continental management and security of the Arctic.

If bombast, posturing, ans sputtering are a good defense of "our" Arctic, then Harper has it aced. Otherwise, he is forefeiting it to the pragmatic opinion expressed by the rear admiral above.
Gee, how much of that polar-class icebreaker Harper wants built could have been put together with the billion for "security" at G20............and what happened to the three (count 'em, three) military icebreakers Harper promised, and which helped him form the government?
