   • The part of the urban region outside the City of Toronto is often referred to locally as "the 905", the telephone area code that distinguishes it from the 416 area code of the City. Because the 905 has mostly been built up since the 1970s it is also common to regard everything there as "the outer suburbs", a useful name that implies that while this recently developed area is an extension of the inner suburbs it is nevertheless different from them. 2013, Edward Relph, Toronto: Transformations in a City and Its Region (Metropolitan Portraits), University of Pennsylvania Press, →ISBN, retrieved 10 Jan 2021, page 77:
