In January 1917, the battery becoming part of the Canadian Corps Heavy Artillery, it was renamed No. 2 Canadian Siege Battery, Canadian Garrison Artillery, on 29 January 1917. The battery was engaged in the Battle of Vimy Ridge as part of Counter-Battery (Fire) Group No.3, 2nd Canadian Heavy Artillery Group, before soon being moved to 57th Heavy Artillery Group. At Vimy Ridge, the Canadian Corps Heavy Artillery consisted of eighteen heavy, twenty-six medium, nine 60-pounder, and two BL 6-inch Mk VII naval gun batteries, formed into eight siege and three counter-battery fire groups. Following the action on Vimy Ridge, the battery was again significantly engaged in the Canadian Corps action in the taking of Hill 70, just east of Loos and north of Lens, again as part of a reconstituted 2nd Canadian Heavy Group, in August 1917.
