COGIM

Overview

COGIM is a domestic submarine cable system located entirely within Canada, connecting the province of Quebec across a total length of 438 km. The cable serves an intra-Canadian corridor, linking a coastal point on the Gaspé Peninsula with the remote archipelago of Les Îles-de-la-Madeleine in the Gulf of St. Lawrence. It is owned and operated by Télébec, a Quebec-based telecommunications provider.

Route and Landings

Both landing points are located in the province of Quebec, Canada. The cable makes landfall at L'Anse-à-Beaufils on the Gaspé Peninsula, and at Les Îles-de-la-Madeleine, an archipelago situated roughly in the centre of the Gulf of St. Lawrence. These two termination points define the cable's role as a dedicated link between mainland Quebec and an island community separated from the continental shore by open water.

Ownership and Operators

COGIM is wholly owned by Télébec. Télébec is a regional telecommunications carrier operating in Quebec, providing services to communities across the province, including remote and island locations that depend on submarine infrastructure for connectivity.

Status and Timeline

COGIM entered service in 2005 and has been operational for approximately 21 years. The cable currently connects its two Quebec landing points and remains in service.

Regional Context

Within the Canadian submarine cable landscape, COGIM's 438 km length places it in the shorter range of domestic systems, exceeding approximately 42% of other cables serving the same national corridor. Canada hosts 18 submarine cables across 44 landing points, with an average cable length of around 877 km, reflecting the country's vast coastlines and dispersed island communities.

Among cables operating in this corridor, COGIM is considerably shorter than the long-haul EXA North and South system and the cross-ocean Greenland Connect, and also shorter than the more recent EXA Express. It is, however, comparable in purpose to shorter regional systems such as Persona and the planned EAUFON 3, which similarly address connectivity needs for specific segments of the Canadian maritime environment. COGIM predates several of these systems, having entered service in 2005.

Strategic Role

COGIM provides submarine cable connectivity between the Gaspé Peninsula and Les Îles-de-la-Madeleine, an island group whose geographic isolation in the Gulf of St. Lawrence makes overland or terrestrial routing impractical. By linking these two Quebec communities, the cable supports telecommunications access for a population that would otherwise lack a direct fixed-line connection to mainland infrastructure. Its relatively compact length of 438 km reflects the specific geographic gap it was designed to bridge.
