While under repair at Halifax , the two submarines survived the Halifax Explosion unscathed . The Royal Canadian Navy then devised a plan to utilise the two subs in anti-submarine training for the surface vessels . This was done on Cape Breton Island . '' CC-2 '' and '' Shearwater '' were sent to Bras d'Or Lake and trained the trawler and drifter crews in the use of their hydrophones . The two subs finished the war as training vessels , not going on patrol again before the Armistice
