RCN Public Affairs, 25 July 2021.
When HMCS Corner Brook began its undocking on June 13, it became the most modern submarine in the RCN. Corner Brook had been in an Extended Docking Work Period (EDWP) since 2014 in Esquimalt, B.C.
In addition to repairs, the EDWP included several notable upgrades, such as a new communication mast, called the Universal Modular Mast, which will allow high-speed, highly secure, jam-resistant satellite communications with shore, and the BQQ-10 sonar suite.
After completing its Extended Docking Work Period, the submarine was transferred from the Graving Dock to Ogden Point, both in Esquimalt, B.C. Using a group of self-propelled, motorized platforms, the sub was moved through a complex series of turns through the Graving Dock facility and onto the Seaspan Careen lift barge, which then transported it to Ogden Point.
