Toronto streetcars have long used a loud metallic gong as a warning bell, rung by the operator to alert pedestrians, cyclists and drivers that a large vehicle is approaching or about to move. The sound is closely associated with the Toronto Transit Commission network, especially its downtown routes, and has become an instantly recognisable part of the city's soundscape. Online, creators reuse the clip to add authentic transit atmosphere, signal a vehicle arrival or give a scene a distinctly Toronto feel, keeping the classic bell familiar to new audiences.
