Submarine Cables Mapping


Emera Newfoundland & Labrador (ENL) installed two submarine high voltage electricity cables across the Cabot Strait in 2017 to interconnect the electrical grids of Nova Scotia and Newfoundland. The cables run parallel from Cape Ray, NL and make landfall at Point Aconi, NS.

For the protection of all marine vessels equipment, as well as the personal safety of marine crews, it is imperative that interactions with these high voltage electrical cables are avoided.

The cable locations were published on the hydrographic chart update with Canadian Hydrographic Services (CHS) in December 2017. The following CHS charts were updated: 4002, 4003, 4015, 4022, 4045, 4277, 4363, 4367 and 4823.

The locations of the submarine cables are available through the links below:
