The Imperial Munitions Board (IMB) was the Canadian branch of the British Ministry of Munitions, set up in Canada under the chairmanship of Joseph Wesley Flavelle. It was formed by the British War Cabinet to alleviate the Shell Crisis of 1915 during the First World War. The Board was mandated to arrange for the manufacture of war materials in Canada on behalf of the British government.
It was the general and exclusive purchasing agent on behalf of the War Office, the Admiralty, the British Timber Controller, the Department of Aeronautics and the Ministry of Munitions, and also acted as an agent for the United States Ordnance Department. [1]
Shortly after the outbreak of World War I, the War Office approached the Canadian Department of Militia and Defence as to the possibility of supplying shells. [2] Its Minister, Sam Hughes, appointed a Shell Committee in September 1914 to act on the War Office's behalf. [2] The following were its members:

When the contracts became mired in political patronage that led to profiteering, [lower-alpha 7] [12] David Lloyd George sent Lord Rhondda to Canada to investigate. [12] Lionel Hitchens [lower-alpha 8] and R.H. Brand then came over and approached Joseph Wesley Flavelle to help form the IMB, and this move received the approval of Prime Minister Sir Robert Borden. [13] In December 1915, the following were appointed:

As Chairman, Flavelle had full administrative and executive authority. [21] The Board operated through twenty departments, of which the most important were Purchasing and Steel, Shipbuilding, Explosives, Forging, Aviation, Timber, Fuze and Engineering. [21]
As certain shell manufacture contracts had been granted to persons that did not even have workshops, their holders were given deadlines to either start manufacturing them or forfeit the contracts. [13] This led to political controversy later on, as the losers started to falsely accuse Flavelle of profiteering as well, because of his connection to the meat packing business. [13]
In a 1917 address, Carnegie reported that the Board was then dealing with 650 factories in 144 towns, stretching from Halifax to Victoria. [22] By 1918, the extent of its acquisition of lumber required the operation of 67 logging camps in British Columbia. [23] The British Government was responsible for all its expenditure. [24]
The British War Cabinet also noted the extent of Canada's war production in 1918:
15 per cent of the total expenditure of the Ministry of Munitions in the last six months of the year was incurred in that country. She has manufactured nearly every type of shell from the 18-pounder to the 9.2-inch. In the case of the 18-pdr., no less than 55 per cent of the output of shrapnel shells in the last six months came from Canada, and most of these were complete rounds of ammunition, which went direct to France. Canada also contributed 42 per cent of the total 4.5 shells, 27 per cent of the 6-inch shells, 20 per cent of the 60-pdr. H.E. shells, 15 per cent of the 8-inch and 16 per cent of the 9.2-inch. In addition Canada has supplied shell forgings, ammunition components, propel[l]ants, acetone, T.N.T., aluminum, nickel, aeroplane parts, agricultural machinery and timber, beside quantities of railway materials, including no less than 450 miles of rails torn up from Canadian railways, which were shipped direct to France. [23]
Because the private sector was unwilling or unable to operate in certain fields, the Board established seven "National plants" for the production of explosives and propellants, and one for the manufacture of airplanes. [25] The Board also oversaw the production of ships and aircraft.
It also formed several subsidiaries to perform several of the manufacturing functions, which were spread across Canada. These included:

When the Montreal Gazette profiled the War Toronto on its first visit to Montreal, on April 30, 1919, they described her as the last of 46 vessels built for the Imperial Munitions Board. [35]
The IMB was dissolved in 1919. The process began immediately after the Armistice, when the Ministry of Munitions directed that it would be implemented through the following stages: [24]
When contracting was transferred from the Shell Committee to the IMB, Flavelle decided that fair wage clauses would not be inserted into future contracts that were granted, although British and Canadian authorities did not object to continuing the prior practice. [36] As the IMB was a British agency, its activities with respect to labour relations did not fall under federal jurisdiction until the passage of an order in council in March 1916 that extended the application of the Industrial Disputes Investigation Act, 1907, [37] [38] but Flavelle's opposition continued. [39] This had the effect of disrupting relations with the Trades and Labour Congress of Canada, [40] which would lead to the outbreak of strikes in 1918 and massive labour confrontations in 1919. [41]
Cordite is a family of smokeless propellants developed and produced in Britain since 1889 to replace black powder as a military firearm propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the barrel of the gun.
Sir Samuel Hughes, was the Canadian Minister of Militia and Defence during World War I. He was notable for being the last Liberal-Conservative cabinet minister, until he was dismissed from his cabinet post.
Nobel is a village on the shores of Parry Sound, Ontario, Canada. It is in the Municipality of McDougall in the District of Parry Sound. The community is named after Alfred Nobel, the inventor of dynamite.
The Ordnance QF 18-pounder, or simply 18-pounder gun, was the standard British Empire field gun of the First World War-era. It formed the backbone of the Royal Field Artillery during the war, and was produced in large numbers. It was used by British Forces in all the main theatres, and by British troops in Russia in 1919. Its calibre (84 mm) and shell weight were greater than those of the equivalent field guns in French (75 mm) and German (77 mm) service. It was generally horse drawn until mechanisation in the 1930s.
The Shell Crisis of 1915 was a shortage of artillery shells on the front lines in the First World War that led to a political crisis in the United Kingdom. Previous military experience led to an over-reliance on shrapnel to attack infantry in the open, which was negated by the resort to trench warfare, for which high-explosive shells were better suited. At the start of the war there was a revolution in doctrine: instead of the idea that artillery was a useful support for infantry attacks, the new doctrine held that heavy guns alone would control the battlefield. Because of the stable lines on the Western Front, it was easy to build railway lines that delivered all the shells the factories could produce. The 'shell scandal' emerged in 1915 because the high rate of fire over a long period was not anticipated and the stock of shells became depleted. The inciting incident was the disastrous Battle of Aubers, which reportedly had been stymied by a lack of shells.
The Minister of Munitions was a British government position created during the First World War to oversee and co-ordinate the production and distribution of munitions for the war effort. The position was created in response to the Shell Crisis of 1915 when there was much newspaper criticism of the shortage of artillery shells and fear of sabotage. The Ministry was created by the Munitions of War Act 1915 passed on 2 July 1915 to safeguard the supply of artillery munitions. Under the very vigorous leadership of Liberal party politician David Lloyd George, the Ministry in its first year set up a system that dealt with labour disputes and fully mobilized Britain's capacity for a massive increase in the production of munitions.
A filling factory was a manufacturing plant that specialised in filling various munitions, such as bombs, shells, cartridges, pyrotechnics, and screening smokes. In the United Kingdom, during both world wars of the 20th century, the majority of the employees were women.
The BL 8-inch howitzer Marks VI, VII and VIII were a series of British artillery siege howitzers on mobile carriages of a new design introduced in World War I. They were designed by Vickers in Britain and produced by all four British artillery manufacturers but mainly by Armstrong and one American company. They were the equivalents of the German 21 cm Morser 16 and in British service were used similarly to the BL 9.2-inch howitzer but were quicker to manufacture and more mobile. They delivered a 200 lb (91 kg) shell to 12,300 yd. They had limited service in the British Army in World War II before being converted to the new 7.2 in (180 mm) calibre. They also equipped a small number of Australian and Canadian batteries in World War I and by the US Army in that war. They were used in small numbers by other European armies.
Sir Joseph Wesley Flavelle, 1st Baronet was a Canadian businessman.
The Ordnance BL 9.2-inch howitzer was a heavy siege howitzer that formed the principal counter-battery equipment of British forces in France in World War I. It equipped a substantial number of siege batteries of the Royal Garrison Artillery. It remained in service until about the beginning of World War II.
The Canary Girls were British women who worked in munitions manufacturing trinitrotoluene (TNT) shells during the First World War (1914–1918). The nickname arose because exposure to TNT is toxic, and repeated exposure can turn the skin an orange-yellow colour reminiscent of the plumage of a canary.
Henry Westman Richardson was a Canadian businessman and Senator.
The number 106 fuze was the first British instantaneous percussion artillery fuze, first tested in action in late 1916 and deployed in volume in early 1917.
Col. David Carnegie, was a British scientist, engineer and Liberal Party politician who worked for the Canadian government.
SS War Toronto was a small freighter built in Toronto, in 1918, by Toronto Dry Dock & Ship Building Company Limited. She was one of 72 cargo vessels built under the authority of Canada's Imperial Munitions Board for wartime service in the First World War, and one of the 46 vessels with hulls built of wood. She had a carrying capacity of 2,500 deadweight tons. Toronto Shipbuilding also constructed a sister wood-hull ship at the same time, the SS War Ontario.
Defence Industries Limited (DIL) was a subsidiary of Canadian Industries Limited (C-I-L), founded in 1939 to manufacture munitions for use in World War II. The company operated in number of locations in Canada, in the provinces of Ontario, Quebec, and Manitoba. Its Pickering Works shell-filling plant, along with nearby housing, grew into the town of Ajax.
William Lionel Hichens (1874–1940) was a British industrialist, chairman of Cammell Laird from 1910.
The Munitions Inventions Department (MID) of the British Ministry of Munitions was created during the First World War in 1915. Its administrative structure encompassed university and industrial laboratories, private workshops, and military experimental grounds. The department made us of the experimental facilities of other government agencies, including the National Physical Laboratory at Bushy House and the Department of Scientific and Industrial Research (DSIR). Two sister organisations were formed: The Board of Invention and Research (BIR) which was established in July 1915 to support the Admiralty, and the Air Inventions Committee (AIC), which supported the Air Board once it became become fully operational in the summer of 1917.
The 1916 Hamilton machinists' strike was a labour dispute in Hamilton, Ontario, Canada involving between 1,500 and 2,000 workers employed in the manufacturing of munitions and other materials for World War I. It began on June 12 and involved those employed at all of the major manufacturers, including the National Steel Car Company, the Steel Company of Canada, Dominion Steel Foundry, Canadian Westinghouse Electric & Manufacturing Company, Fensom Elevators. Involving members of the International Association of Machinists, Amalgamated Society of Engineers, and unorganized workers, it ended in defeat for Hamilton's machinists.
