Canada
Canada's submarine cable footprint spans the North Atlantic and Pacific, anchored by a mix of legacy and active systems that reflect decades of transatlantic investment and the country's geographic reach across two ocean basins.

Gateway to Two Oceans
Canada occupies an unusual position in the global submarine cable network. Straddling both the North Atlantic and the North Pacific, and extending into Arctic latitudes, the country has accumulated connections across multiple generations of undersea infrastructure — from the earliest coaxial systems to later fibre deployments.
The cable register for Canada lists thirteen systems at various stages of life: active, planned, and retired. That breadth signals long and sustained engagement with the submarine cable industry rather than a reliance on a handful of contemporary builds.
The Atlantic Spine
The North Atlantic corridor dominates Canada's cable profile. Systems including CANTAT-3, the 360atlantic network (formerly Hibernia Atlantic), TAT-1, TAT-2, TAT-9, Project Express, and CANTAT-2 all trace routes across the Atlantic, connecting Canada to Europe and providing the country's most heavily developed international bandwidth corridors. The presence of both retired systems — CANTAT-2 sits in that category — and a planned cable alongside active ones shows a network that has been built, extended, and periodically superseded over many decades.
The diversity of transatlantic cables is a structural advantage. Multiple independent systems mean that a single fault does not isolate Canadian traffic from European endpoints. Rerouting options exist, and the depth of the cable list here suggests genuine redundancy rather than token backup.
Pacific and Arctic Reach
Beyond the Atlantic, ANZCAN and FLAG FP-1 extend Canada's connectivity toward the Pacific, while Arctic Link and Greenland Connect reflect the country's engagement with higher-latitude routing — paths that carry strategic interest given Canada's northern geography. CANUS-1 reinforces the Canada–United States corridor, underscoring how tightly the two countries' networks are woven together at the infrastructure level.
Arctic-routed cables remain a relatively small share of global capacity, but for Canada they represent a natural fit with national geography and potential future traffic patterns as northern routes attract broader industry interest.
Landing Infrastructure
Herring Cove in Nova Scotia is the documented landing point on the Coral Sea Cables register. Nova Scotia's eastern position makes it a logical terminus for transatlantic cables — the province's coastline sits closer to the United Kingdom than any other part of the Canadian mainland. Additional landing stations likely exist elsewhere in the country; the register continues to be compiled as documentation is verified.
A Mature, Layered Network
Taken together, Canada's cable mix reflects a mature cable nation — one with historical depth in transatlantic systems, meaningful Pacific connections, and emerging Arctic routes. The variety of vintages and operators across the list points to a network built by many hands over many years rather than a single planned deployment.
