The bedrock under Tasiujaq consists of sedimentary and metamorphic formations, chiefly sandstone, slate, greywacke and argillite.

In the 1950s, when the federal government opened a school in Kuujjuaq and started delivering social services, many Inuit congregated around the emerging village.

The wildlife resources of Kuujjuaq, however, were scarce and many Inuit were forced to rely on governmental financial aid.

In 1963, the Northern Quebec directorate of the provincial government, hoping to partially remedy this problem, decided to create a new village on the south shore of Leaf Lake where wildlife resources were more plentiful.

Qaamanialuk Paanga was finally selected because it was easily accessible by boats used for summer hunting and fishing, nearby Finger River provided the necessary drinking water, and there was room to construct a landing strip.

In 1971, once the community was organized, a cooperative store was established independently by residents, and is now associated with the Federation of Co-operatives of Northern Quebec.
