Contained within the 3rd Edition (1957) of the Atlas of Canada is a main map that shows eleven condensed maps of the Federal Electoral Districts as created by the Representation Order circa 1952. There are 265 members representing 263 districts (Halifax and Queen's on Prince Edward Island each have two members). The map is surrounded by eleven maps showing urban areas. All of these urban maps are at the same scale - 1:650 000. A table on the map lists the names of most districts. However, the districts in the urban insets are named directly on each inset map.
