Canada had claimed Hans Island was clearly in its territory, as topographic maps originally used in 1967 to determine the island's coordinates clearly showed the entire island on Canada's side of the delimitation line. However, federal officials reviewed the latest satellite imagery in July 2007, and conceded that the line went roughly through the middle of the island. This presently leaves ownership of the island disputed, with claims over fishing grounds and future access to the Northwest Passage possibly at stake as well.
