The federal government is pledging to work with its American counterparts after the U.S. claimed parts of the Arctic sea floor that Canada also wants.

Grantly Franklin, spokesman for Global Affairs Canada, said in an email that Canada expects to follow the process set out in a United Nations treaty despite the fact the U.S. hasn't ratified the Convention on the Law of the Sea.

"Canada and the U.S. are in frequent communication with regards to the continental shelf in the Arctic and have expressed their commitment along with other Arctic states to the orderly settlement of overlapping claims," Franklin wrote.

The U.S. filed its extended continental shelf claim last month with the United Nations agency that evaluates such requests. As expected, it includes a large chunk of the Beaufort Sea floor that Canada also seeks to control.

"It's stuff that we've always suspected they were going to do," said Rob Huebert, a professor at the University of Calgary's Centre for Military, Security and Strategic Studies. "The Americans have been very careful not to have any overlap with the Russians but they have overlap with us."

A large part of the overlap concerns how the border should be drawn. Canada wants it extended directly north from the 141st meridian while the U.S. says it should be drawn at a 90-degree angle from the shoreline.

Under the UN treaty, countries have the right to manage the environment and develop natural resources on the ocean floor if they can prove their continental shelf extends more than 200 nautical miles, or about 370 kilometres, from their coast and is a natural extension of the continent. Rights to an extended continental shelf don't include control over matters such as fisheries or shipping.

The UN doesn't rule on boundaries, but evaluates the science behind each country's claim and leaves it to them to negotiate a settlement.

Although the U.S. has not signed the Convention on the Law of the Sea, it has pledged to work within it.

"The U.S. views the (convention) definition of the continental shelf as customary international law and has adhered to the definition in delineating its continental shelf limits," Franklin wrote.

The American decision to follow the convention is good news for the rule of international law, Huebert said.

He said Canada's willingness to work with a country outside the convention may weaken the treaty. But given the small chance the U.S. will sign on any time soon, Huebert called the move "politically smart."

Huebert notes that Canada, which filed its claim in 2019, now has overlapping claims with Russia and Denmark as well as the U.S.

"Every single one of our Arctic neighbours has an overlap with us," said Huebert.

He said growing geopolitical tension around the world isn't going to make drawing those lines on the waves any easier.

"You have to resolve things peacefully if you're part of the convention," he said.

"But you have to overlay that with the geopolitical situation we have now. We're in such a conflictual environment — with Russia, primarily, and now our two key allies. It's one ugly chicken soup."

Canada's submission would bring 1.2 million square kilometres of sea floor under Canadian control, a territory about the size of Alberta and Saskatchewan combined.

The Amerasian Basin, which includes the disputed area of the Beaufort Sea, is thought to include significant oil reserves. The United States Geological Survey estimates it could hold up to 10 billion barrels of oil equivalent — although that number is considered a "probabilistic" assessment based on Arctic geology rather than a hard figure.

The UN body that assesses the quality of the science in each country's expanded continental shelf claim is expected to take years to arrive at its decisions.

All these "overlaps" are, of course, driven by one thing - the probability of underlying fossil fuel. Fossil fuel that is currently the source of the violent climate changes we are experiencing, and predicting will get worse, probably for far longer than the potential life span of any oil under the Beaufort sea floor. Not only will exploiting this potential resource only worsen our fossil fuel addiction, the mere presence and drilling for that resource is bound to contaminate the Beaufort Sea, exactly as the off shore oil extraction has lethally damaged the Gulf of Mexico. An Arctic "dead zone" will spell the end of Arctic wildlife both within the waters and above. How can we maintain a healthy planet when we so ruthlessly destroy its livable mantle?

Be careful what you wish for; what you are prepared to debase for truly filthy lucre. Eventually, if humanity survives, we will finally get around to punishing those who refuse to clean up the ghastly residue of their greed. Eventually, the despoilers and their enablers, will pay the due penalties they incur by their theft of global resources.

Yup. Unfortunately, the rest of us will almost certainly pay along with them.

I wouldn't count on the despoilers not declaring bankruptcy.
But I do wonder how those who claim on the one hand that we are "robbing" our children and grandchildren in multiple ways that can only actually exist with selective fact choosing, novel bookkeeping, and/or non-existent laws or practices. And yet while they claim that the world cannot do without carbon fuels, they're not contemplating leaving any behind for those "future generations."

Here's a 2015 map that includes the US proposition, and seems by the projection of the northernmost point of the US-Can contested territory to favor the US claim.
