EAUFON 3

Overview

EAUFON 3 is a domestic submarine cable system in Canada, spanning approximately 900 kilometres along the eastern coast of Quebec. The cable serves the Nunavik region, connecting seven remote communities in northern Quebec and forming part of the undersea infrastructure that provides connectivity to this sparsely populated Arctic coastal corridor.

Route and Landings

All landing points are located in Quebec, Canada. The cable reaches seven communities: Aupaluk, Kangiqsualujjuaq, Kangiqsujuaq, Kangirsuk, Kuujjuaq, Quaqtaq, and Tasiujaq. These settlements are spread across the Nunavik territory along the shores of Hudson Strait and Ungava Bay, areas with limited overland infrastructure and significant reliance on alternative connectivity solutions.

Ownership and Operators

EAUFON 3 is owned by Tamaani Internet, a provider focused on delivering broadband services to communities in northern Quebec. Tamaani Internet operates as the primary connectivity provider for Nunavik, serving Indigenous and remote communities in the region.

Status and Timeline

EAUFON 3 is planned for service with a Ready for Service date of 2027. Once operational, it will extend Tamaani Internet's submarine cable network in the Nunavik region.

Regional Context

Canada's domestic submarine cable landscape includes several systems of varying scale, from long-haul cables such as EXA North and South at 12,200 kilometres and EXA Express at 4,600 kilometres, to regionally focused systems closer in scope to EAUFON 3. Within Nunavik specifically, EAUFON 3 will follow EAUFON 1, which entered service in 2022 at 1,175 kilometres, and EAUFON 2, which became operational in 2024 at 675 kilometres. Together these three cables represent a staged expansion of submarine connectivity across northern Quebec's coastal communities. The Persona cable, at 800 kilometres and in service since 2008, and Greenland Connect, at 4,580 kilometres, round out the broader regional picture of cables operating in and around this northern corridor.

Strategic Role

EAUFON 3 will extend undersea fibre access to seven remote communities in Nunavik that face geographic isolation and limited terrestrial infrastructure options. At 900 kilometres, it broadens the reach of Tamaani Internet's existing submarine network in the region, covering additional coastal settlements along Ungava Bay and Hudson Strait. The cable's seven landing points reflect the dispersed nature of Nunavik's population, where submarine systems offer a practical means of delivering broadband connectivity across distances that would otherwise be difficult to serve.
