Canada: Addendum to Partial Submission to CLCS (Arctic Ocean)

As previously reported, on 23 May 2019 Canada had made a partial submission to the Commission on the Limits of the Continental Shelf (CLCS) regarding its continental shelf in the Arctic Ocean. On 19 December 2022 Canada submitted its Addendum to the Partial Submission of Canada to the Commission on the Limits of the Continental Shelf regarding its continental shelf in the Arctic Ocean, see executive summary (french), to the CLCS. As summarised in the executive summary:

This addendum to the 2019 partial submission delineates additional outer limits of continental shelf, including along the full length of the Central Arctic Plateau (Lomonosov Ridge, Alpha Ridge and Mendeleev Rise, with the intervening Podvodnikov Basin and Makarov Basin), beyond 200 M from the baselines from which the breadth of the territorial sea is measured.

Noting in particular article 77 [of UNCLOS], Canada reserves the right to submit information in respect of other areas or portions of its continental shelf.

This submission is made, consistent with article 76(10) and article 9 of Annex II of [UNCLOS] without prejudice to future delimitation between Canada and the Kingdom of Denmark, the Russian Federation and the United States of America.

Addendum to the Partial Submission of Canada to the Commission on the Limits of the Continental Shelf regarding its continental shelf in the Arctic Ocean, pp. 5 and 10.
