Area codes 905, 289, 365, and 742 are telephone sphere codes in the north american Numbering Plan ( NANP ) for the Golden Horseshoe region that surrounds Lake Ontario in Southern Ontario, Canada. The number plan area ( NPA ) comprises ( clockwise ) the Niagara Peninsula, the city of Hamilton, the regional municipalities of Halton, Peel, York, Durham, and parts of Northumberland County, but excludes the City of Toronto. The area codes form an overlie design for the same geographic area, where area code 905 was established in October 1993 in an area code split from area code 416. When 289 was overlaid on June 9, 2001, all local calls required ten-digit dial. On April 13, 2010, the canadian Radio-television and Telecommunications Commission ( CRTC ) introduced another overlay code, area code 365, [ 1 ] which became operational on March 25, 2013. [ 2 ] [ 3 ] The number plan area surrounds the city of Toronto ( sphere codes 416/647/437 ), leading locals to refer to the chiefly suburban cities surrounding Toronto as “ the 905 ” or “ 905 belt ”. It is bound by the 519/226/548 overlie area in the west, 705/249/683 in the north, 613/343 in the east, and New York State area code 716 on the eastern prong of the Niagara Peninsula. The incumbent local exchange carrier is Bell Canada.
history [edit ]
Area code 905 was once assigned to Mexico City during the time when Mexico was expected to become a member of the north american Numbering design. however, Mexico established its own number design within the area code designation of +52. The assignment of 905 was last formally withdrawn by February 1, 1991. By October 1991, sphere code 905 had been assigned to relieve exchanges in the Golden Horseshoe, which was and still is Canada ‘s largest toll-free calling zone. The Golden Horseshoe ‘s explosive growth in the second half of the twentieth century and the corresponding expansion of telecommunications service would have made another area code necessity in any event. however, the timetable was advance because Canada ‘s arrangement of total allotment does not use number pool as a relief measuring stick. alternatively, each competitive local commute carrier ( CLEC ) is arrogate blocks of 10,000 numbers, which correspond to a individual three-digit prefix, for every rate center in which it plans to offer overhaul. Most pace centres do not need that many numbers, but overindulgence numbers can not be reassigned elsewhere once they are assigned to a rate centre. The problem was not as severe in the Golden Horseshoe as in the remainder of Canada since then as now, numbers tended to be used up fairly promptly. however, the number allocation system did not allow phone number blocks to be reassigned from smaller pace centres to the Toronto pace center. The proliferation of cell phones, pagers, facsimile machines, and dial-up Internet connections made it obvious that the Golden Horseshoe needed another area code. automatic rifle phone number identification ( ANI ) in some central function switching systems in the count plan area started operation on October 11, 1992. The new area code entered service on October 11, 1993. permissive dial of 416 continue across the Golden Horseshoe until January 1, 1994. however, portions of the 905 territory have remained ever since a local anesthetic call to Toronto. The creation of sphere code 905 was intended as a long-run solution. however, five years after its introduction, area code 905 was close to exhaustion far sooner than anticipated, again due to the proliferation of cell phones and pagers. By 1999, the CRTC had established an ad hoc committee to study code relief design for area code 905. A split of the NPA was considered, with assorted options being presented :
- a geographic split by municipality (either two-way or three-way)
- a geographic split of concentric rings around Toronto
- a realignment of NPA boundaries
- a distributed overlay
The overlay option was chosen because it would cause the least disruption and was supported by all of the carriers. A schism would have forced customers to change their numbers for the second time in less than a ten and forced the reassignment of cellular telephone numbers. For the same reason, Toronto was overlaid with area code 647 ( and by and by 437 ).
The 289 NPA overlie was approved by the CRTC on August 15, 2000 in Order CRTC 2000–772. The order had the CRTC direct Bell Canada to implement a ten-digit local dial plan. [ 4 ] Area code 289 came into service on April 7, 2001, and it had come into full operation by June 9, 2001. Area code 905 was formally exhausted in November 2005, just twelve years after its creation. All modern central office prefixes were assigned with NPA 289. character of the problem stemmed from the creation of single-tier megacities across Ontario at the turn of the millennium. Many of the blow up cities are split between multiple rate centres, which have never been amalgamated. An case is Hamilton, Canada ‘s tenth-largest city, which is split between nine rate centres. That applies besides to newer cities, which were created prior to the introduction of the 905 code. For exercise, Mississauga, the largest city in the NPA, and the sixth-largest city in Canada, is split between five rate centres flush though it has been a individual municipality since 1974, but there is a single Mississauga list in the call reserve. Another exemplar is Vaughan, which is divide between three rate centres and separate of a fourth even though it has been a single municipality since 1971. Unlike Mississauga, Vaughan is not even listed in the telephone record, which lists the diverse pace centres individually. The Golden Horseshoe ‘s continue growth caused area code 365 to be assigned for far stand-in on March 25, 2013. besides, area code 742 was assigned on October 16, 2021. [ 5 ] [ 6 ] A count plan exhaust analysis of 2020 projected an exhaust date of March 2023 for the number plan area. [ 7 ]

In democratic culture [edit ]
The term the 905 or the 905 belt is used to describe the suburban areas of the Greater Toronto Area, [ 8 ] while Toronto proper is referred to as the 416. The terminus 905er is often used pejoratively by Toronto residents to refer to suburban residents outside the city. [ 9 ] canadian knocker Maestro rendered court to the area code in his song “ 416/905 ( TO Party Anthem ) ” ; “ TO ” ( pronounced “ T ” “ O ” ) is an abbreviation or nickname locals use when referring to the city of Toronto. In June 2015, Maple Leaf Sports & Entertainment announced the formation of an NBA Development League team for the Toronto Raptors based in Mississauga called Raptors 905. The term has been used in the context of canadian politics, where the 416 is a stronghold of Liberals and NDP, whereas the 905 ( excluding Hamilton ) historically had potent ties to the Progressive Conservative Party. [ citation needed ] The region has, however, backed opposition parties as a protest vote, including both the NDP in the 1990 provincial election and the Liberals in the 2003 provincial election, as a backfire to the incumbent government. [ citation needed ] In both cases, the opposition party was elected to government with hard back of the 905 area. [ citation needed ] The 2011 federal election saw the 905 region become predominately represented by candidates of the Conservative Party of Canada, while one third of the 416 ridings were won by Conservatives, many through vote divide between the Liberals and NDP. In the 2019 federal election, the Liberals successfully held all 25 ridings in the 416, which they won in 2015. however, the parties were fighting over control over the 905 as historically, winning the 905 is samara to parties forming government. [ 10 ] In the end, most 905 ridings were won by the Liberals over the Conservatives. [ 11 ] The Liberals ultimately beat the Conservatives and formed a minority politics with the documentation of the 905. [ 12 ]
