The District of Ungava was a regional administrative district of Canada's Northwest Territories from 1895 to 1920, although it effectively ceased operation in 1912. It covered the northern portion of what is today Quebec, the interior of Labrador, and the offshore islands to the west and north of Quebec, which are now part of Nunavut.
The name "Ungava" is of Inuktitut origin, meaning "towards the open water". It is believed to be in reference to the lands inhabited by the Ungava Inuit, who lived at the mouth of the Arnaud River which flows into Ungava Bay.
When created in 1895, the District of Ungava covered all of modern-day northern Quebec, the interior of modern-day Labrador, and all the islands in James Bay, the Hudson Strait, Ungava Bay, and the eastern side of Hudson Bay.
Ungava's southern continental boundaries initially ranged as far south as Lake Timiskaming, well below James Bay on the modern Ontario/Quebec border. Note, however, that a dispute over the location of the boundary between Canada and Labrador (a dependency of the Dominion of Newfoundland) meant both Canada and Newfoundland claimed the far eastern portion of Ungava, an area shown in shaded red on the accompanying maps. This boundary dispute would not be settled during the time the district of Ungava was in existence.
At the time of its creation, Ungava covered over 1,000,000 square kilometres, although just under 15% of its area was also claimed by Newfoundland. However, just three years later with the adoption of the Quebec Boundary Extension Act, 1898, the southernmost portion of the District of Ungava (excluding offshore islands) was transferred by the Parliament of Canada to Quebec. All told, the act transferred approximately 250,000 square kilometres of Ungava to Quebec, the majority of which now lies in the modern-day Jamésie region of the province. After the transfer was complete, the mainland area of the District of Ungava reached no further south than the mouth of the Eastmain River—about halfway down James Bay, as shown on the accompanying map.
