In 1954, the London Junior Chamber of Commerce in association with the London Health Association organized a mass tuberculosis survey in London, Ontario with the technical assistance of the Ontario Department of Health Division of Tuberculosis Prevention. According to the digest, the object of the survey was "to interest the adult population of London in having a chest x-ray to detect early symptoms of tuberculosis". The survey was financed by the London Health Association through the sale of Christmas Seals.

A London X-Ray Survey Council comprised of eight executive members that were responsible for the organization and execution of the survey. According to the digest, a total of 48,440 x-rays were collected as a result of the survey. The majority of persons who were x-rayed were workers from industrial plants, and any institutions with 50 or more employees, as well as many high schools students from various districts and school boards. Publicity for the survey centered around the theme "Check Your Chest", which was widely published in local newspapers and broadcast on local radio and television.

The London General Omnibus Company (LGOC) was the principal bus operator in London, England, between 1855 and 1933. Between 1909 and 1912, it was also a motor bus manufacturer. It was founded in 1855 to amalgamate and regulate the many independent horse-drawn omnibus services operating in London. Originally an Anglo-French enterprise, it was also known as the Compagnie Generale des Omnibus de Londres. Within a year, the LGOC controlled 600 of London's 810 omnibuses. In 1908, the LGOC bought the Road Car Company, the Vanguard Company, and its other main rivals, thereby gaining a virtual monopoly in London. In 1911, it absorbed the Great Eastern London Motor Omnibus Company (previously known as London Motor Omnibus Company). In 1933, the LGOC became part of the new London Passenger Transport Board.

The London Dock Company was established by a group of merchants, shippers, and bankers in 1796 and it was formed in Wapping, East London in 1800. The work on the London Docks began in 1801. They were constructed by hand and required hundreds of labourers, mainly economic migrants from Ireland. The London Dock Company negotiated a 21-year monopoly to manage all vessels carrying rice, tobacco, wine, and brandy (except those from the East and West Indies). In 1864, the London Docks were amalgamated with St Katharine Docks. The docks were closed to shipping in 1969.
