Sea Islands

These tables refer to major and minor islands. A major island has a land area exceeding 129 square kilometres, a minor island is smaller than that. The perimeters of some minor islands were considered too small to be reliably measured.

All islands were enumerated and the total island count obtained for each region. Rocks or islets depicted on 1:250 000 maps as minute dots were not included.

The Canadian Arctic Islands were measured as two geographic groups: 1) the Queen Elizabeth Islands and 2) Other Arctic Islands. These two tables make it clear which of the major islands are in Nunavut (NU), or Northwest Territories (NT).
