Working until his death in 1940, Goss made photographs for a range of municipal departments. Some of his best-known images were taken for the Works and Health Departments. For the Works Department, he photographed street cleaning, the construction of new roads, and major infrastructure projects, such as the city's new hydroelectric system and the
Bloor Viaduct. His photographs of street grading and widening, bridge, underpass, and sewer construction, street cleaning, and garbage disposal were used as records to assist with the routine business of the Works Department, which, at the time, was focused on improving the physical environment of the city. Medical Health Officer Dr.
Charles Hastings enlisted Goss's help in his crusade to improve public health. Goss photographed unsanitary and overcrowded conditions for the Health Department, and Hastings used Goss's photographs as evidence in his 1911 report on slum conditions. Many of Goss's photographs for the Health Department were never published, but were used internally to identify problems, to track the progress of particular projects, or to report on new technologies and methods for carrying out the Department's work. With Goss as the city photographer, photographs quickly became an important resource in many aspects of Toronto's municipal government. == Artistic interests ==
