Canada will seek possession of the North Pole

Canada signalled intentions to claim the North Pole and surrounding Arctic waters while announcing Monday the filing of a UN application seeking to vastly expand its Atlantic sea boundary.

After a decade of surveying the country's eastern and far north seabeds and gathering supporting evidence, a claim was submitted to the Commission on the Limits of the Continental Shelf on Friday.

Foreign Affairs Minister John Baird said the filing mainly concerns the outer limits of Canada's continental shelf in the Atlantic Ocean.

But it also includes "preliminary information concerning the outer limits of (Canada's) continental shelf in the Arctic Ocean," he said.

"We have asked our officials and scientists to do additional work and necessary work to ensure that a submission for the full extent of the continental shelf in the Arctic includes Canada's claim to the North Pole," he told a press conference.

"Fundamentally, we are drawing the last lines of Canada. We are defending our sovereignty," added Arctic Minister Leona Aglukkaq.

Asserting sovereignty over an expansive Arctic archipelago and surrounding waters has been a key plank of Canadian Prime Minister Stephen Harper's Tories in the past three elections since 2006.

But Russia and Denmark are expected to file overlapping claims, which could lead to confrontation between the Arctic neighbours.

Interest in the polar region has flared up as rising temperatures open up shipping routes and make hitherto inaccessible mineral resources easier to exploit.

The North Pole seabed itself is not believed to hold large reserves but has symbolic value for the countries in the region, which also includes Norway and the United States.

Natural Resources Minister Joe Oliver said enlarging Canada's Arctic boundary is important for "Canada's long-term economic prosperity."

Observers, however, note that energy firms face harsh conditions in the Arctic, and environmental concerns could delay resource extraction in the pristine waters.

Just gathering supportive evidence for Canada's claim has been a challenge, commented Fisheries Minister Gail Shea.

"The Canadian Hydrographic Service and the Geological Survey of Canada have collected a great deal of data in areas that are ice-covered, difficult to access, and that in some instances had not previously been surveyed," the minister said.

Scientists also described treacherous mapping expeditions to the coldest reaches of the planet.

Data collection mainly involved the use of aircraft, ice breakers and robot submersibles covering a 58,000-kilometre (36,039.53 mi) stretch of ice-covered waters.

And periodically unpredictable ice conditions forced the emergency evacuation of ice camps, officials said.

Foreign ministry official Hugh Adsett told a technical briefing "substantial progress" has been made in the data collection, but added without specifying a timeline, "there is more work to be done."

"The objective is to obtain the most expansive continental shelf for Canada," he said.

"We do believe that the science will show that the North Pole is part of Canada's continental shelf but we need to acquire the data to conclusively prove this in our submission."

Nations bordering the Arctic currently are entitled to a 200-nautical-mile economic zone from their coastlines, but claims for extending their territories are to be decided under the United Nations Convention on the Law of the Sea.

In order to be successful Canada must show that its continental shelf extends beneath the North Pole, which sits on a slope of the underwater Lomonosov Ridge.

Canada's Atlantic Ocean claim stretches from the shores of its easternmost Nova Scotia province northward along the Grand Banks to the northern tip of Labrador 7,700 kilometres (4,784.56 mi) away.

The area is more than 1.2 million square kilometres (460,000 sqm) in size, or as large as Canada's Western plains.

Canada expects overlapping claims in the Atlantic from Denmark in the Labrador Sea and with the United States south of Nova Scotia.

As well, Canada said France intends to file a submission in respect to its tiny islands in the northwest Atlantic, Saint Pierre and Michelon, "so we may have a dispute with France in the future," the official added.

The UN is scheduled to consider Canada's partial submission in July-August 2014.
