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.
