Area codes 450 and 579

Area codes 450 and 579 are telephone area codes in the North American Numbering Plan for the Canadian province of Quebec, encompassing the off-island suburbs of Montreal, which is served by area codes 514 and 438.

The numbering plan area was split twice: in 1957 to create area code 819, and in 1998 to create area code 450.

On May 2, 2011 a prepaid mobile telephone registered to "Pierre Poutine, Separatist Street, Joliette" at (450) 760-7746 on Bell Mobility's "Virgin" service played a key role in a robocall scandal in which voters in Guelph, Ontario were inundated with calls directing them to the wrong polling station.

Elections Canada traced the automated calls to a disposable cellphone in the 450 area code of Joliette, Quebec, and issued a subpoena to the cellphone provider.
