Maple's proximity to Toronto and its major transportation corridors, and Vaughan's own political support for development, have led to the heavy development and population growth. In 1993, housing development began in the area of what was the Maple Airport. In 1995, it expanded to the western part of Maple. Between 1997 and 1999, urban developments reached the northwestern part of Maple and Melville and the Don to the train tracks. Developments also reached the northeastern part and the southeastern part. Megalot houses began developing northeast of Maple near Dufferin in the late-1990s. The housing developments began up to the Highway 400 in the northwest. Housing developments have begun near Vellore.
