A new 905-242 Oshawa exchange now exists (416-242 existed for some time). On 4th October 1993, 905 area code was officially active, meaning the only numbers in 416 will be in Metro Toronto. 905 consists of all those places in the former 416 territory outside Metro Toronto. As a result, the 416 exchange list was altered accordingly. Some potential pitfalls of the 905 area code are 1) that 905 used to be the area code used to dial Mexico City (Mexico can now be called under the overseas dialing setup); 2) 905 somewhat resembles the adjacent area code 705 to the north thus risking other confusion; 3) at the time of assignment, other area codes such as 210 could have been assigned which would provide faster rotary dialing; there were few area codes left to be assigned in the traditional format in any event, thus limiting the choices of area code. This split will change the dialing of local calls that cross the Toronto boundary ie. dial area code + local number if dialing a local call into or out of Toronto (no 1 + is needed beforehand unless the call is indeed long distance). The split will be completed 25 March 1994 (the end of the "permissible" dialing period in which 905 may or may not be used for calls outside Toronto). In March 1990, the dialing system in 416 was changed to allow for NXX codes (N is a digit from 2 to 8, X is any digit 0 to 9) from the previous NNX prefix format. Basically, area codes style numbers may now be used for exchanges. At the time of the change, the area code 416 had to be dialed for all long distance calls within the old 416 (previously, just 1 + number has to be dialed). Obviously, there will be no longer be any such thing as long distance dialing within 416 any more with the split. 1+905+number will be needed for such calls to Hamilton or Oshawa that are long distance from Toronto. The first exchanges to get the new style of prefixes were of the form 50X, 51X, 60X and 61X. Note that exchanges like 514, 519, 613 were not assigned, and may never be assigned since it may become necessary to use the area codes for purposes of local dialing across area code boundaries. Indeed, since 905+number will be required to dial from Toronto to outlying local exchanges, 905 will not be assigned as a prefix. New prefixes of the 40X, 41X and 81X form were subsequently placed in service. Some exchanges in the 90X or 91X series may be assigned for WATS line service as has been the case previous to the change to extra exchange prefixes. The exact assignments are unknown at this time. Possible mistakes resulting in calls to 911 may also be a factor in avoiding new prefixes of the 91X form at this time (and 911 itself will not become a prefix in ordinary service for obvious reasons). Any blanks in the list mean the exchange is not in service as of last report, or the exchange number is being used for some other unknown purpose. There are sometimes things like billing codes used internally by Bell, for instance. There may also be other exchanges for such things as cellular telephones, pagers and test circuits that are not usually mentioned in phone books, etc. An effort was made to list each exchange that appears to be active, even if it is listed with question marks to mark an unknown status. Some exchange profiles follow. Sometimes an exchange can be primarily devoted to use by a single company, since a Centrex or similar system can take up most or all of a telephone exchange prefix. Here are some of these exchanges in Toronto (note that not all numbers in a specific exchange need to be related to a particular company or group of services; some parts of these exchanges can go to other services, companies or even to ordinary telephone lines): 205 - Canadian Broadcasting Corp. 217 - Canadian National 224 - Federal government 314 - Ontario government 392 - Metro Toronto municipal 393 - TTC/Metro schools/other Metro 394 - Etobicoke municipal 395 - North York municipal 396 - Scarborough municipal 539 - Toronto Transit "time line" 592 - Ontario Hydro 599 - Bell Canada 739 - Federal government 813 - Hospital for Sick Children 866 - Bank of Nova Scotia 867 - Bank of Montreal 954 - Federal government 956 - VIA Rail Canada 965 - Ontario government 973 - Federal government 974 - Royal Bank 978 - University of Toronto 980 - Bank of Commerce 982 - Toronto-Dominion Bank The above list is not complete; there may be other exchanges designated for a predominantly single company or usage. Thanks to Ray Chow (ray.chow@canrem.com) for some updates to the chart effective the 17 February 1993 edition. Bell Mobility cellular uses the following 416 exchanges: 200, 201, 209, 254, 346, 347, 407, 460, 518, 540, 580, 592, 605, 606, 801, 802, 805, 806, 931, 948 Cantel cellular uses the following 416 exchanges: 219, 230, 258, 315, 399, 402, 409, 414, 417, 418, 440, 464, 505, 520, 543, 565, 587, 616, 617, 618, 716, 720, 726, 804, 917, 930 Note that cellular numbers sometimes share the same number space with other (more conventional) phone numbers, while other exchanges are exclusively dedicated to cellular or pager use. In addition, 870 and 872 are Toronto exchanges used for recorded messages, broadcast station contest lines, ticket agencies, and other "mass calling" purposes. These kind of lines can be called "choke" exchanges, to handle conditions that can get very congested. Federal government in Toronto uses three SL-1 facilities: 1) 4900 Yonge (presumably under 224 prefix), 2) 4905 Dufferin (739) and 3) a site identified in a federal directory only as "6205 Kestrel" (Mississauga, or some city other than Toronto? Or did they mean 6205 Keele? Presumably this site takes care of the 954 and 973 numbers). Provincial government prefixes are 324, 963, 965 (under Centrex I, which had been using the older Intercity Network (ICN) but will be replaced soon, if not already) and also 314, 325, 326 and 327 (under the newer Queens Park Telecommunications System (QPTS) using the newer Ontario Communications Network (OCN)). All Ontario government telephone services are expected to be converted to QPTS/OCN as facilities are put into place. The old methods of the ICN, including special city codes of the form 8xx to get to certain destinations, will then be obsolete. It also appears that many of the 965 numbers have been changed to other prefixes, perhaps meaning 965 is being phased out for Ontario government purposes. Exchanges like 320 and 942 seem to be active from some places, but not from others. These may be test exchanges, or exchanges to be activated in the near future, or localised testing exchanges. It could also be a programming error in a few telephone switches. 410 was used for testing or special purposes until recently when it appears that this is in service for Toronto numbers. 997 is an exchange used for numbers that will identify the telephone number that is calling. 996 is used for some testing as well. 958 and 970 are used for other tests and were accessed by dialing 1+416+ beforehand (perhaps 1+905+ after the split?). 320 is also a possible test exchange. 999 is sometimes used for testing; if so, the exchange will give another dial tone when 999 + the number that's calling is dialed.
