Ultra Electronics, TCS traces its roots to 1903 when the Marconi Wireless Telegraph Company of Canada Inc. (MWTCC) was founded in Montreal, providing long range maritime communications for ships and coastal stations starting in early 1904. On April 14, 1912 at 10:25 pm (EST), the first distress call of the Titanic was received by one of the company’s magnetic detectors at the Cape Race station in Newfoundland. In May 1920, the company initiated the first regular, scheduled radiobroadcast program in the world from its William Street facility, experimental emissions having started earlier in 1919. The company deployed the first Police mobile communication system in the country in 1930 and was offering ruggedized, rapidly deployable wireless communication solutions as early as 1934. In 1956, after supporting Canada and various allied forces with a number of Brigade/Battalion level, vehicle level and shipborne Navy radios in WW2, the company became the first Canadian firm to design a complete microwave radio relay system, the Mid-Canada Defence Line. Manufacturing of the first tactical digital radio relay equipment for US DoD began in 1966. From 1925 to 2000, the company was known as Canadian Marconi Company (CMC). It was acquired by Ultra Electronics in 2002 and is Ultra's center of excellence for tactical communications and electronic warfare.
