TheArctic Archipelago, also known as theCanadian Arctic Archipelago, is anarchipelago lying to the north of the Canadian continental mainland, excludingGreenland (an autonomous territory of theDanish Realm, which is, by itself, much larger than the combined area of the archipelago), andIceland (an independent country).
Situated in the northern extremity of North America and covering about 1,424,500 km2 (550,000 sq mi), this group of 36,563 islands, surrounded by theArctic Ocean, comprises much ofNorthern Canada, predominatelyNunavut and theNorthwest Territories.[4] The archipelago is showing someeffects of climate change,[5][6] with some computer estimates determining that melting there will contribute 3.5 cm (1.4 in) to therise in sea levels by 2100.[7]
Around 2500 BCE, the first humans, thePaleo-Eskimos, arrived in the archipelago from the Canadian mainland. Between 1000 and 1500 CE, they were replaced by theThule people, who are the ancestors of today'sInuit.
British claims on the islands, theBritish Arctic Territories, were based on the explorations in the 1570s byMartin Frobisher. Canadian sovereignty was originally (1870–80) only over island portions that drained intoFoxe Basin,Hudson Bay andHudson Strait. Canadian sovereignty over the islands was established by 1880 when Britain transferred them to Canada.[8] TheDistrict of Franklin—established in 1895—comprised almost all of the archipelago. The district was dissolved upon the creation of Nunavut in 1999. Canada claims all the waterways of theNorthwest Passage asCanadian Internal Waters; however, most maritime countries view these asinternational waters.[9][failed verification] Disagreement over the passages' status has raised Canadian concerns about environmental enforcement, national security, and general sovereignty. East ofEllesmere Island, in theNares Strait, liesHans Island, ownership of which is now shared between Canada and Denmark, after a decades-long dispute.[10][11][12]

The archipelago extends some 2,400 km (1,500 mi) longitudinally and 1,900 km (1,200 mi) from the mainland toCape Columbia, the northernmost point on Ellesmere Island. It is bounded on the west by theBeaufort Sea; on the northwest by theArctic Ocean; on the east by Greenland,Baffin Bay andDavis Strait; and on the south byHudson Bay and the Canadian mainland. The various islands are separated from each other and the continental mainland by a series of waterways collectively known as theNorthwest Passage. Two large peninsulas,Boothia andMelville, extend northward from the mainland. The northernmost cluster of islands, includingEllesmere Island, is known as theQueen Elizabeth Islands and was formerly the Parry Islands.
The archipelago consists of 36,563 islands, of which 94 are classified as major islands, being larger than 130 km2 (50 sq mi), and cover a total area of 1,400,000 km2 (540,000 sq mi).[13]
The islands of the Canadian Arctic over 5,000 km2 (1,900 sq mi), in order of descending area, are:[1] As of 2021[update] the total population of all islands in the Arctic was 23,073.[2][3]

After Greenland, the archipelago is the world's largest high-Arctic land area. The climate of the islands isArctic, and the terrain consists oftundra except in mountainous regions. Most of the islands are uninhabited; human settlement is extremely thin and scattered, being mainly coastalInuit settlements on the southern islands.
Of the more than 36,000 islands, only 11 are populated. Baffin Island, the largest, also has the largest population of 13,309.[2] The population accounts for 67.37 per cent of the 19,355 people in theQikiqtaaluk Region, 56.51 per cent of the population of the Arctic Archipelago, and 35.38 per cent of the population of Nunavut.[2][3]
