Leaside: a 1913 plan with postwar houses
Most Leaside houses are decades younger than its street plan. A subsidiary of the Canadian Northern Railway developed the town to a design by Frederick Todd, it was incorporated in 1913, and many of its streets are named for railway executives. Industry came first: Todd reserved the southeast quarter for it, and 52 companies were in place by the end of the 1930s. Housing lagged. The population was 938 in 1931, 6,183 in 1941 and 16,233 in 1951, and residential building only came in full after the Second World War, as single-family homes on narrow, curving streets and culs-de-sac. For floors, that places most Leaside houses between the late 1930s and the 1950s, when plywood was replacing plank as the standard subfloor but was still nailed down rather than glued. A nail holds a panel in place without drawing it tight to a joist that is slightly out of plane, and that small gap is where the noise starts decades later.
