U.S. negotiating claims disputes with Canada in Arctic bilaterally

The major remaining U.S. ECS boundary to be determined in the Arctic is shared by the United States and Canada. As was the case with Russia, the U.S. and Canada have approached the demarcation of this boundary cooperatively. The two nations have a mutual interest in determining the extent of their respective continental shelves and identifying their respective areas of ECS.

To that end, the U.S. and Canada have conducted a series of joint scientific operations in the Arctic to collect bathymetric and seismic data to map the continental shelf.⁴⁰ These data will enable the United States and Canada to negotiate a bilateral treaty delimiting their respective continental shelves and areas of ECS in the Arctic Ocean in the same manner as the U.S. and Mexico did in the Gulf of Mexico. United States need not join the convention to demarcate areas of its Arctic EEZ and ECS, secure jurisdiction and control over these areas, and develop the hydrocarbon resources in these areas. Such demarcation has been and will continue to be conducted in cooperation with neighboring Arctic nations regardless of whether the U.S. is a UNCLOS member.
