HMCS Protector (1939 - 1964) - Royal Canadian Navy base HMCS Protector, also known as the Point Edward Naval Base (and sometimes Sydney Naval Base), was located next to Sydney Harbour, on Nova Scotia's Cape Breton Island. It was founded in 1940 and used by the navy during World War II. It was mainly used to provision, protect and repair the various merchant marine convoys to Quebec, Halifax, and the United Kingdom. It was a main combat zone during the Battle of the St. Lawrence and the more general Battle of the Atlantic. It continued to be utilized during the Cold War's early stages. It was decommissioned in 1964.
