Kangirsuk, QC, Canada: Submarine Cable Landing Point

Kangirsuk is an Inuit village in northern Nunavik, Quebec, Canada, situated approximately 230 kilometres north of Kuujjuaq along a remote stretch of Arctic coastline. The community is accessible only by air and, during late summer, by boat — a geographic reality that underscores the significance of submarine cable connectivity for such an isolated settlement. One submarine cable lands at Kangirsuk, linking this northern community into a domestic Canadian cable corridor.

That cable is EAUFON 3, a regional system scheduled for delivery in 2027 and currently in draft status. With a length of 900 kilometres, EAUFON 3 connects Kangirsuk to other points within Canada, establishing an intra-Canadian submarine link serving the broader Nunavik region. The cable represents a meaningful development for a community where overland connectivity routes are effectively absent.

Cables Landing at Kangirsuk

EAUFON 3 is a 900-kilometre submarine cable with a scheduled ready-for-service date of 2027, currently in draft planning. The cable connects landing points entirely within Canada, positioning Kangirsuk as one terminus on a domestic intra-Canadian submarine route. As a draft system, EAUFON 3 reflects ongoing efforts to extend submarine cable infrastructure northward into Nunavik and the broader Arctic communities of Quebec.

Regional Context

Among Canadian landing points, Kangirsuk hosts a single cable, placing it alongside Addenbroke Island, BC as a single-cable terminus within the national network. Other Canadian landing points — including Kangiqsujuaq, QC, Puvirnituq, QC, Halifax, NS, Prince Rupert, BC, and Vancouver, BC — each host two cables, representing greater redundancy. Across Canada's 155 landing points, Kangirsuk's single-cable count places it in the top 97 percent by cable count, reflecting how the country's submarine cable network spans a wide range of locations, from major coastal hubs to remote northern communities.

Network Role

Kangirsuk functions as a single-cable terminus on the EAUFON 3 system, a domestic Canadian route that extends submarine connectivity into one of the more remote reaches of Quebec's northern coastline. The 900-kilometre cable ties Kangirsuk into an intra-Canadian corridor, providing a fixed undersea data path for a community that has no overland connectivity alternatives and is unreachable by sea for most of the year.

Within the broader Canadian submarine cable graph, Kangirsuk represents the northward reach of domestic cable infrastructure into Nunavik. Its presence as a planned landing point, alongside peers such as Kangiqsujuaq and Puvirnituq, signals an expanding pattern of submarine investment in Arctic Quebec, where remote Inuit communities increasingly appear as named endpoints in submarine cable network planning.
