For the British Dominions they faced more difficult choices than what would had been the case if the London had been on good terms with Washington. Outside the Union of South Africa, the other three White Dominions within the Empire faced hard choices about how best to support the Mother Country in her time of need. None was more highlighted than that of the Dominion of Canada. They shared over a 5,000 mile border with the United States that gave little in terms of defense advances for a nation with such a small population as Canada against a nation that had such a much larger population than her.
Canada had been slowly expanding its army since the early 1900s and by 1915 it fielded the largest army of all the White Dominions. Yet this army had been designed with the goal of slowing the Americans down in the eastern part of the nation till the British could reinforce Canada and help turn the tide against the Americans. Yet the British had committed the British Expeditionary Force to the early battles in the Great War for it to almost be totally destroyed as a fighting force. The British Army was in needed of troops to help fill the gap created by the beating the BEF took as they trained a new army to take up fighting in France. Yet Canada didn’t want to send its whole army for fear of what might happen if the US decided to join the Central Powers and attack north. This would lead to the Conscription Crisis of 1914.
In Canada things were complicated as they had the French Catholics in Quebec and the English Protestants within the rest of the nation. During the buildup of the army starting in 1902 the Canadians had only formed one all Quebecois regiment. The rest of the units were totally controlled by the English Protestants. The Canadian Government was steadfast in its refuser to raise further Quebecois regiments. As the war started many English Protestants rushed to sign up for the war and service. Quebecois didn’t. They knew that so long as there was only the single Quebecois regiment within the Canadian Army they would get treated poorly in the barrack life that awaited them in service if they joined as the Quebecois regiment was already filled out to its full allotment of soldiers.
Ottawa also understood that if it sent all the whole army to Europe there would be little left to defend Canada with. To that end they floored a bill to start conscription within Canada. It would start conscription within Canada but it didn’t make a difference between English Canadian or French Canadian. Further it didn’t raise anymore Quebecois regiments under its program designed to grow the Canadian Army size tenfold within a year. It also made clear that men conscripted would be sent overseas under the plan to maintain a force both in Europe and Canada. The Quebecois didn’t want anything to do with this and took to the streets when PM Thomas Sproule pushed the bill through.
Sproule was long known as anti-French leader within the Conservative Party and had been elected to the leadership position in 1909 and became PM after the failure of the Naval Bill of 1910 which caused the fall of the Liberal Party. Sproule had never been warmly greeted within Quebec but the Military Service Act was too much for Quebecois. Things got so bad that Sproule was forced to send the army in too put down the rioting within a few cities within Quebec. It also forced Sproule to change the bill to appease Quebecois. He made it so men who were conscripted would only serve in Canada. He also created more all French Quebecois regiments. Still this only raised the number of Quebecois regiments to six but it was a huge improvement to Quebecois.
Even after things died down the number of regiments Canada sent to Europe were far short of what the British were hoping for. But by the start of 1915 Canadian Divisions were taking up part of the British line on the Western Front. They were able to form three divisions which were attached to the BEF in Europe by the start of 1915 with a fourth division forming in Canada for shipment to Europe slated to happen by the spring of 1915. They were making one mistake through, the units going to Europe got the latest stuff with the units staying behind getting cast offs. This was because they only had a limited production ability to make weapons in 1914 and the Mother Country was just about tapped out itself in terms of making weapons. The US the only source not already in the war that could supply weapons refused. This created a logistical nightmare for the Canadian Army that was kept in the Americas. This led to units raised in British Colombia being equipped with Japanese Type 29 Rifles[1] to units raised in the Maritimes Provinces Lee-Metford Rifles that were taken out of storage for use. Some training units were using even older Martini-Henry Rifles.
In terms of the Royal Canadian Navy things were fairly limited. Their primary focus during their military buildup had been the army and not the navy. As such the navy got scraps for the most part. Their Atlantic coast was totally depended on the Royal Navy. This was even with Halifax being a major hub for the Royal Navy in this part of the world, the Royal Canadian Navy just didn’t have the men to spear for defending the Atlantic, Pacific, and the Lakes. On the Pacific side, they were based out of Esquimalt on Vancouver Island. Even then they were still fairly depended on the Royal Navy for help. Their Pacific Fleet was built around three protected cruisers with all three be second hand ex-RN units. The oldest was built in 1890 with the newest being built in 1899.
Then there was the Lakes, i.e. the Great Lakes and Lake Champlain. Under the terms of the Treaty of Washington that was signed in 1871 made the lakes a total demilitarized zone. However, as tension built between London and Washington some within the USN questioned this treaty and their voices grew loader after 1899. Then in 1902 the year that is marked as the start of the Anglo-American Naval Arms Race Washington passed a note to both Ottawa and London that they were withdrawing from terms of the Treaty of Washington and returning to the terms of the older Rush-Bagot Treaty. Ottawa decided not to withdraw from the terms of Rush-Bagot as they couldn’t afford the men and money to match the US in a naval race on the lakes. This led to the Canadians building a gunboat that fell within the limits of the terms of the Rush-Bagot. What they got was a slow design[2] that could only reach 10 knots and armed with a single old QF 12 pounder 12 cwt naval gun. This weapon was selected as it fell within the terms of Rush-Bagot and the Royal Navy wasn’t willing to design a gun that met the 18 pound shell limited as the larger naval guns were well over this limit.
Yet there were no plans to expand the Royal Canadian Navy in 1915 even as the Conscription Crisis played out. They simply didn’t have the men for it. Outside part of the Pacific Squadron moving south to help defend the Sandwich Islands and the rest of the Pacific Squadron saying to guard the Pacific Coast the RCN didn’t expect to see much in terms of fighting in this war.
