In June 2022, Canada and Denmark established a 1.23 kilometer (0.76 mile) land boundary roughly dividing the small island of Tartupaluk or Hans in half. The uninhabited island is in the Nares Strait, a narrow waterway between Canada and Greenland. The boundary line follows a ravine before connecting with the maritime boundary, which was also adjusted by the 2022 Agreement. The Agreement resolved a decades-old dispute over the sovereignty of the island and establishes both the longest maritime boundary in the world, at 2,139 nautical miles, and one of the shortest land boundaries.

Canada and Denmark also share a maritime boundary.
