We have always been a destroyer navy, a navy that has small ships capable of doing big things anywhere that Canada needs them to go.
Vice-Admiral Angus Topshee CMM MSM CD, the Vice Chief of Canada's Defence Staff, speaking on June 5th, 2026 at the keel-laying ceremony in Halifax for Canada's first River-class destroyer, the future HMCS Fraser:
By James Patton
Why would Admiral Topshee say that? Well, his nation has 151,019 miles of coast line, the most of any nation in the world. It also has 52,455 oceanic islands, forming a myriad of tight and often shallow passages. The tasks of coastal defense and sovereignty protection for Canada are enormous. For centuries, they have relied on the remoteness of the Arctic to control unauthorized access, but that is changing. Measuring over the North Pole, Russia is about 1,000 miles from the closest spot in Nunavut, Canada's northernmost, and newest territory. Canada is a country of large distances. The distance from the same point to Ottawa is over 2,500 miles. To the folks in Nunavut, Moscow is actually the closer capitol. Moreover, in recent years Russia has claimed big chunks of the Arctic seabed and is now running shipping channels through the Arctic Ocean.
In spite of geographic reality, until 1910 Canada didn’t even have a navy. They relied on the British Royal Navy (RN) (and good relations with the U.S.) for their maritime protection. Eventually around 1900, considerable pressure was brought on the Ottawa government to rein in clandestine American fishing in Canadian waters. Canadians felt that the RN was overlooking this activity, with an eye to preserving harmonious relations with the Americans. As a result, the Canadian Department of Marine and Fisheries established its Fisheries Protection Service and ordered a patrol vessel from a British shipyard, which was commissioned as the CGS (Canadian Government Ship) Canada in 1904.

While the agitation for fisheries enforcement was building, there was another disturbing revelation: in accordance with the Anglo-Japanese Alliance of January 30th, 1902, the British decided that, in the event of war, the maritime defense of the west coast of Canada was to be provided by the Imperial Japanese Navy (IJN). Indeed, after war was declared, the IJN formed a North American Task Force (Kenbei Shitai), and the Japanese armoured cruiser Izumo, a British-built ship sporting 8-in. gun batteries (a veteran of the 1904 Battle of Tsushima Strait), duly arrived at Esquimalt, British Columbia (BC) on August 25th, 1914. Before that, however, folks in BC had already taken a step towards protecting themselves, as we shall learn below.
Before the war, on 4 May 1910, the Dominion parliament had passed the Naval Service Act, which created the Naval Service of Canada. It also created a naval reserve similar to the British and a naval college. The CGS Canada was retitled and transferred over to be a training ship for the new naval college. The Imperial Dockyards at Halifax and Esquimalt were also given over to the new Naval Service. The Act also provided that, in time of war, the vessels of the Naval Service would be placed at the disposal of the British Admiralty “for general service in the Royal Navy.” This provision wasn’t popular with the French Canadians, who insisted that Canadian ships could never be used against France.
The RN agreed to make available to the Naval Service two obsolescent protected cruisers that had been laid up at Devonport for five years; one had even been decommissioned. Both required substantial repairs and updating. The original plan was to use these ships at Halifax for training, since Canada had no sailors ready to serve on warships. However, fisheries enforcement was immediately added to the Naval Service’s rota. In the Birthday Honours of 1911, on 16 August, The Naval Service, barely a year old, became the Royal Canadian Navy (RCN). At the same time the crown also titled the Royal Australian Navy, an amalgamation of colonial patrol vessels that could trace its origin back to the 1830’s.

The first ship added to the Canadian Naval Service was the former HMS Rainbow, of the Apollo class, recommissioned on 4 August 1910. Built in 1891, she displaced 3,600 tons and could do 19.75 knots. She was coal-fired and mounted two 6-in. and six-4.7 in. guns, plus four torpedo tubes. The 6-in. guns were swapped out for Vickers 3-in. QF’s anti-aircraft and artillery guns in 1911. Altogether, she was slow and lightly armed, with a crew of 275. She cost Canada CD$225,000, paid from unspent funds that had been appropriated to the Department of Marine and Fisheries for law enforcement.
After a 15,000 nautical mile trip around Cape Horn that took twelve weeks, she arrived at Esquimalt on Vancouver Island on 7 November 1910. Thereafter she had to operate with a skeleton crew, as most of her British sailors didn’t renew their contracts. Her subsequent service on the west coast consisted of ceremonies, training and very occasional fishery enforcement. In February 1911, she seized one American ship for fishing in Canadian waters. After one more fishery patrol, Rainbow had to be laid up due to insufficient crew, and remained so until 1913, when sailors were transferred over from Halifax.
In May 1914 Rainbow was ordered to Vancouver to intercept a Japanese ship, the Komagata Maru, which was carrying prospective immigrants from India. Canada had passed legislation banning Asian immigration altogether, but these persons claimed that the law didn’t apply to them because they were subjects of the king. Nevertheless, they were denied entry, as the British failed to back up their claim, and Rainbow escorted the Komagata Maru out of Canadian waters.
In August 1914, Rainbow was the largest armed ship that the Allies had in the eastern Pacific, and was ordered to engage two of the German ships then active there, the cruisers SMS Leipzig and SMS Nurnberg. At San Francisco, Rainbow actually missed an encounter with Leipzig by only a day, fortuitous for Rainbow, because she would have been no match for Leipzig. Head to head, the German ship could both outrun or outrange Rainbow. In 1916 and early 1917, on four occasions, Rainbow was used to carry over 48,000 ounces of Russian gold bullion, which was transferred at sea from Japanese ships, and surreptitiously delivered to Vancouver, to be railed to Ottawa for deposit with the Bank of England. After this, Rainbow was decommissioned and deactivated on 8 May 1917, and her crew was sent to Halifax.

The other RN ship transferred to Canada on 6 September 1910 was the former HMS Niobe of the Diadem class, launched in 1897. She displaced 11,000 tons, and was capable of 20.5 knots. She was also coal-fired but heavily armed, mounting 16 6-in. and 14 3-in. guns, plus three torpedo tubes. However, she had a range of just 2,000 miles and required a crew of 760. To acquire the Niobe, Canada paid the Admiralty £215,000.
While on a training cruise on the night of 30 July 1911, Niobe ran aground at Cape Sable, Nova Scotia, probably the most well-known reef in the area. The damage was considerable, causing a permanent reduction in her speed, and she was laid up for six months. Nevertheless, she was returned to service and assigned to a patrol of the Gulf of St. Lawrence led by HMS Lancaster, then from 11-15 September 1914, she escorted the HMT Canada to Bermuda to deliver a battalion of the Royal Canadian Regiment for garrison duty there, relieving a battalion of British regulars that had joined the British 29th Division. On her return journey, Niobe developed mechanical problems which prevented her from leading the first Canadian Expeditionary Force convoy to Europe, which departed on 3 October 1914.

After the repairs, Niobe was assigned to the RN’s 4th Cruiser Squadron, tasked with rounding up German merchant ships along the Atlantic coast. She chased the German raider SS Prinz Eitel Friedrich into internment at Newport News, Virginia, but her boilers were wearing out, and after her patrol on 4-17 1915, she was laid up at Halifax, never to be overhauled, and eventually becaming a depot ship. As such, she was extensively damaged by the Halifax harbor explosion on 6 December 1917. A total of fourteen of her complement were killed, seven of whom had voluntarily boarded the S.S. Mont Blanc to attempt to scuttle the burning ship.
Meanwhile, on 3 August 1914, the fledgling RCN had added two submarines to their fleet. As previously mentioned, in August of 1914 folks in British Columbia felt uneasy about their vulnerability to German raiders. In a Seattle shipyard, there were available two submarines, designed by John Holland’s prestigious Electric Boat Co. of Groton, Connecticut. These had been built for the Chilean Navy, who hadn’t accepted them due to range concerns, and hadn’t paid for them, either. The shipyard approached the BC Prime Minister, Sir Richard McBride (1870-1917), and he agreed that the province would buy them for CD $575,000 each, which was substantially more than Chile owed. (Possibly the first example of WW1 war profiteering?) On the evening of 4 August 1914 (the day the UK declared war on Germany), using battery power, the two boats silently slipped out of Seattle, which was a violation of U.S. neutrality law. The next day the U.S.S. Milwaukee was alerted to intercept the subs but they had already managed to get over to Victoria. British Columbia now had a navy, but only for three days; on 7 August the Dominion government agreed to accept the boats from BC for the RCN and they were commissioned as HMCS CC-1 and HMCS CC-2.

Unfortunately, the new subs proved to have several problems. The most serious was the boats had been built heavier than designed, which made diving tricky. The only solution was to cut back on the fuel and stores that could be carried, which reduced the operating range. Also, the diesel engines tended to overheat. Due to metallurgical fatigue the engine heads would crack after six hours of operation at full speed, so full speed operation was rare. Some of the valves in the buoyancy system were faulty and had to be replaced. Lastly, the subs didn’t come provided with torpedoes. The type specified was the Whitehead Mark IV, which was manufactured at Fiume (today Rijeka, Croatia) in the Austro-Hungarian Empire, and the only Mark IV’s in Canada were deployed on HMCS Niobe.
Due to the range and speed limitations, the CC subs were ineffective for patrolling the west coast, so it was decided to send them to Halifax. After a lengthy odyssey involving numerous port stops for fuel, provisions and repairs, plus frequent episodes of towing (even through the Panama Canal), and a maintenance stopover at Electric Boat’s yard in Connecticut, the boats arrived in Halifax on 17 October 1917. They were there when the harbor blew up, but neither was damaged, and no one was injured. CC-1's engine was never reliable, but CC-2 was successfully used for anti-submarine warfare training on Bras d’Or Lake, an estuary on Cape Breton Island. In August 1918 she was ordered to go to the Mediterranean, but her departure was delayed until it was irrelevant.
To combat the U-boat threat, the RCN had built a ragtag fleet consisting of 12 Battle class purpose-built long-range trawlers and 59 converted drifters that were fast enough to be sub chasers. There were also 63 drifters that were too slow so were converted to mine-sweepers. Of this fleet, 129 vessels were based on the east coast and only four on the west. Despite the complete absence of destroyers in the RCN, U-boats did not sink a single ship which was in a convoy in Canadian waters, a testament both to the effectiveness of shifting Halifax convoys to Montréal and to the RCN’s ability to get the most out its small boats. The three large ships that were sunk in Canadian waters were all attacked while proceeding independently. The only other U-boat victims in Canadian waters were 15 fishing schooners and trawlers sunk by U-156 and U-117 between 20 and 30 August 1918.

In spite of their remarkable achievements, the RCN was criticized for the poor harbor management that many concluded had led to the Halifax Explosion. There was also widespread furor over the ineffective response to the audacious exploits of U-156, which captured the trawler Triumph and turned her into a raider, sinking six other fishing trawlers. There was resentment in certain quarters caused by the involuntary conversion of fishing vessels and sensational public outcry over the HMCS Hochelaga incident, where this converted yacht, escorting a four-ship coastal convoy, refused to go to the defense of trawlers being attacked by U-156. The commander of Hochelaga was relieved, court-martialed and discharged, even though he was following standing orders to never abandon the convoy.
A total of 8,826 Canadian personnel served in the RCN during the war: 388 RCN officers and 1,080 RCN ratings, and 745 Royal Navy Canadian Volunteer Reserve (RNCVR) officers and 6,613 RNCVR ratings. Another 90 RN and Royal Navy Reserve officers and 583 ratings served with the RCN for a grand total of 9,499 sailors. Of these totals, 190 men in RCN service were killed in action, died of wounds, or died of disease or accident. Twenty-one RCN personnel were killed in the Halifax Explosion.

Post-war, the Rainbow, Niobe, CC-1 and CC-2 were all scrapped. The Battle class trawlers were repurposed for fisheries enforcement, the other small boats returned to their owners. In 1920 the RCN received a new fleet: a cruiser, three destroyers and two H-class submarines were transferred from the RN. Due to budget cutbacks, all of these were retired from RCN service by 1927. Beginning in 1939, the RCN had to be reconstituted as a fighting force, which would—at its World War II peak—number 1,140 vessels and 104,722 serving men and women.
