Kuujjuaq, QC, Canada: Submarine Cable Landing Point

Kuujjuaq is a northern village located at the mouth of the Koksoak River on Ungava Bay, in the Nunavik region of Quebec, Canada. As the largest northern village in Nunavik and the administrative capital of the Kativik Regional Government, it represents a significant population centre in Canada's subarctic north. One submarine cable is scheduled to land at Kuujjuaq, connecting it to Canada's broader submarine cable network.

The single cable serving Kuujjuaq, EAUFON 3, links it exclusively to other points within Canada, making this a domestic intra-Canadian submarine cable corridor. This places Kuujjuaq within a category of landing points that extend submarine connectivity into remote northern communities rather than providing intercontinental or transoceanic reach.

Cables Landing at Kuujjuaq

EAUFON 3 is a submarine cable with a length of approximately 900 km, currently in draft status with a planned ready-for-service (RFS) date of 2027. All other endpoints on this cable are also located within Canada, confirming its role as a domestic Canadian submarine cable system. No additional technical specifications are available at this time.

Regional Context

Among submarine cable landing points in Canada, Kuujjuaq hosts one cable, placing it alongside Addenbroke Island, BC as a single-cable landing point, while peers such as Kangiqsujuaq, QC, Puvirnituq, QC, Halifax, NS, Prince Rupert, BC, and Vancouver, BC each host two cables. Canada's submarine cable infrastructure spans 21 cables across 155 landing points, and Kuujjuaq ranks within the top 97% of those landing points by cable count, reflecting the relatively modest but meaningful scale of its connectivity.

Network Role

Kuujjuaq functions as a single-cable terminus within the Canadian domestic submarine cable network. The planned EAUFON 3 system, expected to enter service in 2027, will extend submarine cable reach into the Nunavik region of northern Quebec, connecting Kuujjuaq to other Canadian landing points via a 900 km route. This positions the landing point as part of an emerging class of northern domestic connections rather than as a node in any international or intercontinental corridor.

The arrival of EAUFON 3 will make Kuujjuaq one of several northern Quebec communities integrated into Canada's submarine cable graph, alongside existing peers such as Kangiqsujuaq and Puvirnituq. In a national network where the average cable length is 259 km, the 900 km span of EAUFON 3 underscores the geographic distances involved in reaching subarctic communities, and Kuujjuaq's inclusion highlights the ongoing expansion of Canada's submarine cable footprint into its northern regions.
