On October 13, 2009, the OTN Deployment team began phase 1 of the Cabot Strait Line. Thirty-one acoustic receivers extending northeastward from Cape North, Cape Breton Island, Nova Scotia, Canada, to St. Paul Island, a distance of about 25 km, were set in place. Additional receivers were also deployed to extend the line beyond St. Paul Island to a depth of approximately 370 metres, an important area for cod migration.

Installation of this portion of the array was finished November 11. Plans for phase 2 are under way for the completion of the Cabot Strait Line in 2010, which will extend it all the way across the Strait to Cape Ray, Newfoundland.

Species expected to interact with the line include cod, grey seals, Atlantic bluefin tuna, and Atlantic salmon.
