Puvirnituq, QC, Canada: Submarine Cable Landing Point

Puvirnituq is a northern village in Nunavik, situated on the Povungnituk River near its mouth on Hudson Bay in northern Quebec, Canada. Despite its remote Arctic setting, Puvirnituq serves as a submarine cable landing point, with two cables — EAUFON 1 and EAUFON 2 — making landfall here. Both cables operate within the Canadian domestic corridor, connecting Puvirnituq to other points within Canada rather than to international destinations.

The presence of two cables at this location makes Puvirnituq a modest but meaningful node within Canada's northern submarine cable network. The EAUFON cables collectively represent a regional intra-Canadian route, extending connectivity across what is one of the country's more geographically isolated communities. The two cables arrived in successive years — 2022 and 2024 — indicating a deliberate, phased build-out of submarine infrastructure serving this part of Hudson Bay's eastern coast.

Cables Landing at Puvirnituq

EAUFON 1 is a submarine cable stretching 1,175 km, with a ready-for-service date of 2022. Its status is listed as draft. The cable connects landing points exclusively within Canada, making it a domestic intra-Canadian system. As one of two EAUFON-series cables landing at Puvirnituq, it forms the first of a paired infrastructure deployment in the region.

EAUFON 2 is a shorter submarine cable at 675 km, with a ready-for-service date of 2024. Like its companion, it is listed as draft status and connects Canadian endpoints only. Together, EAUFON 1 and EAUFON 2 provide Puvirnituq with a degree of redundancy uncommon in northern Quebec's submarine cable landscape, with two distinct cable routes serving the community.

Regional Context

Within Canada's submarine cable network — which spans 21 cables across 155 landing points — Puvirnituq shares a two-cable count with several other Canadian landing points, including Halifax, NS; Kangiqsujuaq, QC; Prince Rupert, BC; and Vancouver, BC. Notably, Puvirnituq's fellow Nunavik landing point Kangiqsujuaq also hosts two cables, suggesting that northern Quebec has received particular attention in recent domestic submarine cable deployment. Single-cable sites such as Addenbroke Island, BC, and Ahousat, BC, host less redundancy than Puvirnituq.

Network Role

Puvirnituq functions as a domestic multi-cable terminus, served by both EAUFON 1 and EAUFON 2 within an exclusively Canadian corridor. The combination of a longer 1,175 km route and a shorter 675 km route suggests that the two cables likely connect Puvirnituq to different points along Canada's northern coastline, providing route diversity within the same regional system. The successive RFS years of 2022 and 2024 further indicate an expanding rather than static infrastructure footprint at this landing point.

Within the broader Canadian submarine cable graph, Puvirnituq represents a landing point where phased domestic investment has introduced a measure of redundancy to a remote northern community on Hudson Bay, positioning it alongside other two-cable sites in a country where many landing points are served by only a single cable.
