Baie-Comeau, QC, Canada: Submarine Cable Landing Point

Baie-Comeau is a city in the Côte-Nord region of Quebec, Canada, situated on the southern shore of the St. Lawrence River near the mouth of the Manicouagan River. As a submarine cable landing point, it connects into Canada's broader network of coastal infrastructure, which spans 44 landing points across the country. One submarine cable lands at Baie-Comeau, linking it to other points within Canada and placing it within the domestic corridor served by intra-Canadian submarine connectivity.

The single cable landing here, Sunoque I, connects Baie-Comeau to other Canadian endpoints, making this a domestic rather than intercontinental landing point. While Baie-Comeau's cable count is modest relative to the largest hubs in Canada, its position along the St. Lawrence corridor gives it a defined role in regional submarine cable geography.

Cables Landing at Baie-Comeau

Sunoque I entered service in 1999, currently holding draft status. The cable connects Canadian endpoints exclusively, with all other landing points on the system also located within Canada. No cable length is recorded for Sunoque I in available technical documentation. As an intra-Canadian system, it supports domestic connectivity along its route rather than providing international or intercontinental reach.

Regional Context

Among Canadian landing points, Baie-Comeau ranks in the top 93% by cable count, hosting one cable alongside peers such as Akulivik, QC, Aupaluk, QC, and Aylesford, NS, which also each host a single cable. Other landing points in the broader Canadian network, including Halifax, NS, Kangiqsujuaq, QC, and Puvirnituq, QC, each host two cables, giving them a somewhat greater degree of connectivity diversity. Baie-Comeau's profile is therefore consistent with several other single-cable landing points distributed across Canada's extensive coastline.

Network Role

Baie-Comeau functions as a single-cable terminus within the domestic Canadian submarine cable network. Its connection via Sunoque I links it to other Canadian landing points, supporting intra-national data routing along the St. Lawrence River corridor. As a terminus rather than a multi-cable hub, traffic arriving at or departing from Baie-Comeau is dependent on a single submarine route rather than benefiting from cable redundancy.

Canada's submarine cable infrastructure encompasses 18 cables across 44 landing points, with an average cable length of 877 km and a network history stretching back to 1991. Within that landscape, Baie-Comeau represents the category of single-cable domestic landing points that collectively extend submarine connectivity into coastal communities across the country, filling geographic gaps in the national submarine cable graph.
