St. Pierre and Miquelon Cable

Overview

The St. Pierre and Miquelon Cable is a short regional submarine cable system spanning approximately 200 km. It connects the Canadian province of Newfoundland and Labrador with the French territorial collectivity of Saint Pierre and Miquelon, providing a direct undersea link between these two closely situated jurisdictions in the northwestern Atlantic.

Route and Landings

In Canada, the cable lands at two communities on the Burin Peninsula of Newfoundland and Labrador: Fortune and Lamaline.

In Saint Pierre and Miquelon, the cable lands at two points: Miquelon-Langlade and Saint-Pierre, serving both major islands of the archipelago.

Ownership and Operators

The St. Pierre and Miquelon Cable is owned by the French Authority of St. Pierre and Miquelon, the governing body of the French overseas collectivity. This arrangement reflects the territory's distinct administrative status as a French jurisdiction located off the southern coast of Newfoundland.

Status and Timeline

The cable entered service in 2018 and has been operational for approximately eight years. Saint Pierre and Miquelon's submarine cable infrastructure dates entirely from this system, making 2018 the first year that the archipelago was connected to the broader submarine cable network.

Regional Context

Canada is served by 18 submarine cables landing across 44 points, reflecting a well-developed undersea connectivity landscape. The St. Pierre and Miquelon Cable, at 200 km, is shorter than most cables in the Canadian corridor — longer than approximately one-third of the other systems touching the same countries — which is consistent with its purpose as a short cross-strait link rather than a long-haul route. Regional cables such as EXA North and South, EXA Express, Greenland Connect, and Persona serve far longer distances and different corridors entirely. The more recent EAUFON 1 and the planned EAUFON 3 operate at lengths of 1,175 km and 900 km respectively, similarly oriented toward different connectivity needs within the broader Canadian cable environment.

Strategic Role

By linking two Canadian Newfoundland communities — Fortune and Lamaline — to both inhabited islands of Saint Pierre and Miquelon, this cable provides the archipelago's sole submarine connection to external networks. The four landing points distribute connectivity across both the main island of Saint-Pierre and the larger, less populated island of Miquelon-Langlade, ensuring that the full extent of the French collectivity is served by the system.
