Defence Industries Limited

Canadian Industries Limited, also known as C-I-L, is a Canadian chemicals manufacturer. Products include paints, fertilizers and pesticides, and explosives. It was formed in 1910 by the merger of five Canadian explosives companies. It was until recently a subsidiary of Imperial Chemical Industries until ICI was purchased by AkzoNobel.

The oldest direct ancestor of what would become CIL originally started in 1862, then known as the Hamilton Powder Company. They were created to buy the assets of the former Canada Powder Company, which had formed in 1852. Their major product was black powder, used for blasting. In 1878 the company was purchased by Dr. Thomas C. Brainerd, a U.S. businessman in the black powder industry. In order to provide the massive amounts of explosives needed to build the Canadian Pacific Railway, a new dynamite factory was opened in McMasterville, Quebec. Other black powder plants were acquired in Quebec and the Maritimes and, in 1890, the company opened the first explosives plant in the far west, near Nanaimo, British Columbia. Another major ancestor was the Dominion Cartridge Company, started at Brownsburg, Quebec (just west of Montreal) in 1886 by Captain A. L. ("Gat") Howard, who introduced the Gatling gun into Canada and operated a battery of two of the new weapons during the Riel Rebellion.

In 1910 Hamilton Powder and Dominion Cartridge merged with the Acadia Powder Company, Ontario Powder Company, Standard Explosives Company, Western Explosives Company and Victoria Chemical Company to form the Canadian Explosives Company (CXL). This was a major supplier to the Canadian Expeditionary Force during World War I, which led to the building of a new factory in the newly christened Nobel, Ontario in 1914. CXL also operated another plant across the highway on behalf of British Cordite Limited. All of the Nobel plants closed after the war in 1922, when secondary markets were not forthcoming. Then all was lost in a huge fire in 1923.
