Umiujaq, QC, Canada: Submarine Cable Landing Point

Umiujaq is a northern village situated near the eastern shore of Hudson Bay in Nunavik, northern Quebec, Canada. As a remote Inuit community with a population of 541, its position as a submarine cable landing point reflects the broader effort to extend fibre-optic connectivity to Arctic and sub-Arctic communities along Canada's Hudson Bay coastline. One submarine cable lands at Umiujaq, connecting the village to the regional undersea network that serves northern Quebec.

The single cable serving Umiujaq is EAUFON 1, a regional system that links communities entirely within Canada. This intra-national routing places Umiujaq within a corridor designed to deliver connectivity across the remote northern Quebec shoreline rather than spanning international or intercontinental distances.

Cables Landing at Umiujaq

EAUFON 1 is a submarine cable system stretching 1,175 kilometres, with a ready-for-service year of 2022 (draft status). The cable connects landing points exclusively within Canada, making it a domestic system oriented toward serving communities along the Hudson Bay and northern Quebec region. At 1,175 kilometres, EAUFON 1 is notably longer than the Canadian submarine cable average of 877 kilometres, reflecting the considerable distances between the remote communities it links.

Regional Context

Within Canada's submarine cable infrastructure of 44 landing points and 18 cables, Umiujaq ranks among the single-cable landing points, placing it alongside peers such as Akulivik, QC, and Aupaluk, QC, which also each host one cable. Neighbouring northern Quebec communities Kangiqsujuaq and Puvirnituq each serve two cables, making them somewhat more connected nodes within the same regional network. Umiujaq's profile is consistent with that of several remote northern Quebec landing points that rely on a single domestic cable system for their submarine connectivity.

Network Role

Umiujaq functions as a single-cable terminus on the EAUFON 1 system, serving as one endpoint in a domestic Canadian corridor that runs along the Hudson Bay coastline of northern Quebec. The cable's reach of 1,175 kilometres across an entirely intra-Canadian route positions this landing point as part of a network designed to bridge isolated Arctic and sub-Arctic communities to fibre-optic infrastructure. Umiujaq does not operate as a multi-cable hub, but rather as a terminal node within a regional system.

In the broader Canadian submarine cable graph, Umiujaq represents the extension of undersea fibre connectivity into one of the country's most geographically remote communities, contributing to a pattern of domestic cable deployment across northern Quebec that also includes landing points such as Kangiqsujuaq, Puvirnituq, Akulivik, and Aupaluk. Its presence in this network illustrates how submarine cable infrastructure in Canada reaches well beyond major coastal cities into small, remote northern settlements.
