Alderwood was further disconnected from the rest of Etobicoke Township to the north by the construction of the Queen Elizabeth Way in the 1930s and the industrialisation of much of Etobicoke immediately to the north which cemented Alderwood's closer attachment to the independent municipalities of Long Branch and New Toronto to the south. After the war, increased immigration, particularly from eastern Europe, led to the rapid urbanisation of the area which continued until the end of the 1960s.
