Monument to Merchant Mariners
History: Sydney Harbour played an important role during World War II once a Royal Canadian Navy base, HMCS Protector, was established to stage supply convoys bound for Europe. These convoys tended to be slower and had the prefix SC for Slow Convoy.[12] Convoy SC 7 typified the dangers inherent with the Nazi U-boats off the coast of Cape Breton and Newfoundland during the Battle of the Atlantic, when 20 of the 35 merchant cargo vessels were sunk on their journey to England. Sydney Harbour was one of the hotspots of the Battle of the St. Lawrence. Two notable shipping attacks occurred during this battle: the sinking of the train ferry SS Caribou in October 1942 on its way from North Sydney to Port aux Basques, Newfoundland;[13] and the sinking of the Sydney-based HMCS Shawinigan on 24 November 1944 in the Cabot Strait, near Cape North, on Cape Breton Island.[14] Sydney's coal shipping and steel manufacturing made a significant contribution to the Allied war effort, however federal Minister of Industry, C. D. Howe favoured Central Canada's steel industry given its proximity to a larger workforce and less exposure to coastal attack
