EAUFON 1

Overview

EAUFON 1 is a domestic submarine cable system operating entirely within Canada. Spanning 1,175 km, it serves a northern intra-Canadian corridor, connecting remote communities in northern Quebec along the eastern shore of Hudson Bay. The cable is owned and operated by Tamaani Internet, a provider focused on bringing connectivity to underserved northern communities.

Route and Landings

EAUFON 1 has five landing points, all located in the province of Quebec, Canada. These are Chisasibi, Inukjuak, Kuujjuarapik, Puvirnituq, and Umiujaq — each a remote community situated along the Hudson Bay coastline. The five landings reflect a concentrated regional footprint, serving communities that have limited access to terrestrial network infrastructure.

Ownership and Operators

EAUFON 1 is wholly owned by Tamaani Internet. Tamaani Internet is a northern Quebec internet service provider that focuses on delivering broadband connectivity to Cree and Inuit communities across the region.

Status and Timeline

EAUFON 1 entered service in 2022 and has been operational for approximately four years. The system is currently in service, providing active connectivity across its five landing points in northern Quebec.

Regional Context

Within Canada's submarine cable landscape, EAUFON 1 occupies a distinct niche as a shorter, regionally focused system serving northern Quebec communities. At 1,175 km, it is longer than 75% of other cables operating in the same national corridor, which reflects the geographic challenges of reaching dispersed Arctic and subarctic communities across Hudson Bay. Regional peers include EXA North and South (12,200 km, RFS 2001), EXA Express (4,600 km, RFS 2015), Greenland Connect (4,580 km, RFS 2009), and Persona (800 km, RFS 2008). More closely related in scale and purpose are EAUFON 2 (675 km, RFS 2024) and the planned EAUFON 3 (900 km, expected RFS 2027), which together suggest a growing family of cables developed by Tamaani Internet to progressively extend submarine connectivity across the region.

Strategic Role

EAUFON 1 provides submarine-based broadband connectivity to five isolated communities in northern Quebec that would otherwise rely on satellite or other limited forms of transmission. By landing at Chisasibi, Inukjuak, Kuujjuarapik, Puvirnituq, and Umiujaq, the cable addresses a connectivity gap in one of Canada's most remote coastal corridors. The presence of EAUFON 2 and the forthcoming EAUFON 3 in the same corridor indicates continued investment in expanding this undersea network infrastructure across Hudson Bay.
