history [edit ]

Area code 514 served the entire Montreal area for over half-a-century. however, by the mid-1990s, it was on the brink of exhaustion because of Montreal ‘s rapid growth and Canada ‘s inefficient arrangement of number allocation. All competitive local exchange carriers in Canada are allocated blocks of 10,000 numbers for every rate center in which they plan to offer service, even in the smallest hamlets. even though most rate centres do not need closely that many numbers, a number can not be reallocated elsewhere once it is assigned to a carrier and rate centre. That resulted in thousands of waste numbers. By the recently twentieth century, that made a irregular area code necessary in Canada ‘s second-largest toll-free calling partition. Area code 450 enter military service in 1998. The count plan area wholly surrounds sphere code 514, which was confined to the Island of Montreal and a few surrounding islands, and so it is one of the six pairs of “ ring sphere codes ” in the number plan, and the entirely one in Canada. For that argue, Montrealers sometimes refer to the off-island suburbs as “ les 450 ” ( the 450s ), much like the suburb of Toronto are called “ the 905. ”

On May 7, 2009, the CRTC ruled that area code 438, which had been used as an overlay for area code 514 since 2006, would be extended to overlay sphere codes 450 and 514. [ 1 ] however, a former decision changed that to overlay only area code 450 with the new area code 579, effective August 21, 2010. [ 2 ] On May 2, 2011, a postpaid mobile call registered to “ Pierre Poutine, Separatist Street, Joliette, ” at ( 450 ) 760-7746 on Bell Mobility ‘s “ Virgin ” service played a key function in a robocall scandal in which voters in Guelph, Ontario were inundated with calls directing them to the amiss poll station. [ 3 ] [ 4 ]

Area code 354 was formally assigned as of February 2, 2019 as an extra sphere code for the 450/579 overlay complex, [ 5 ] but the relief action was suspended indefinitely on October 8, 2019, and that area code is not in consumption. [ 6 ] The incumbent local rally carrier ( ILEC ) for the 450 and 579 territory is Bell Canada. The major competitive local switch over carriers ( CLECs ) are Vidéotron and Telus .
