  • Les Îles-de-la-Madeleine, QC, Canada: no other cable lands within 50 km.

On an island this means losing the submarine link; on the mainland traffic can still go over land.

Counted: other international cables landing in the same country (domestic cables between points of one country are not a way out), other cables at landing points within 50 km, and whether the country has land links. Not counted: cable capacity, operator contracts and satellite. Use as a first look at dependence, not as a statement of what would happen.

About the COGIM Cable System

Overview

COGIM is a submarine cable system located entirely within Canada, connecting two regions in the province of Quebec across a span of 438 km. Operational since 2005, the cable links the mainland at L'Anse-à-Beaufils on the Gaspé Peninsula with Les Îles-de-la-Madeleine, an isolated archipelago in the Gulf of St. Lawrence. Owned by Télébec, a regional telecommunications provider, COGIM plays a critical role in bridging the geographic gap between these two communities. Its purpose is to ensure reliable connectivity for the residents of Les Îles-de-la-Madeleine, who face significant challenges due to their remote location. The cable is an important piece of infrastructure in the Canadian telecommunications network, addressing the specific needs of this intra-provincial corridor.

Route and Landings

COGIM connects two landing points within Quebec, Canada: L'Anse-à-Beaufils and Les Îles-de-la-Madeleine. L'Anse-à-Beaufils is a coastal community situated on the eastern edge of the Gaspé Peninsula, a region known for its rugged coastline and maritime heritage. This location serves as the mainland gateway for the cable. Les Îles-de-la-Madeleine, the cable's second landing point, is a remote archipelago in the Gulf of St. Lawrence, approximately 105 km from the nearest mainland shore. The islands are geographically isolated, surrounded by open water, which makes submarine cable connectivity essential for telecommunications access.

The Gulf of St. Lawrence, where the cable is laid, is a vast and ecologically significant body of water bordered by Quebec, Newfoundland and Labrador, Prince Edward Island, and Nova Scotia. The cable's route across this gulf reflects the strategic need to connect these two communities separated by challenging maritime geography. By providing a direct link, COGIM bypasses the limitations of satellite or overland routing, ensuring stable and high-capacity telecommunications services.

Ownership and History

COGIM is owned and operated by Télébec, a regional telecommunications company serving communities across Quebec. Télébec specializes in providing connectivity to areas that are often underserved due to geographic isolation or low population density. The cable was commissioned and entered service in 2005, marking a significant milestone in improving connectivity for Les Îles-de-la-Madeleine. As a wholly owned asset of Télébec, COGIM is part of the company's broader strategy to enhance infrastructure in remote regions of the province.

The cable has remained operational for nearly two decades, demonstrating its durability and reliability in the challenging marine environment of the Gulf of St. Lawrence. Its deployment reflects a commitment to addressing the unique connectivity needs of Quebec's island communities, which depend on submarine cable systems for access to telecommunications services that mainland regions take for granted.

What Our Measurements Show

Our monitoring confirms that COGIM remains operational and continues to provide reliable connectivity between its two landing points. The cable's relatively short length of 438 km contributes to its efficiency and stability, as shorter systems typically face fewer technical challenges compared to longer transoceanic cables. The Gulf of St. Lawrence's seabed conditions, characterized by varying depths and sediment types, appear to have been well managed during the cable's installation, ensuring long-term performance.

The cable's role in connecting L'Anse-à-Beaufils and Les Îles-de-la-Madeleine is particularly significant for the latter, as our probes indicate consistent data transmission rates that support the archipelago's telecommunications needs. This infrastructure is vital for the economic and social well-being of the island community, enabling access to services such as internet, phone, and emergency communications. The cable's performance highlights its importance in bridging the geographic divide between mainland Quebec and the Gulf's remote islands.
