It looks like not only Toronto is growing, but the Province of British Columbia will also be issued a new area code starting June 1, 2013 according to the CRTC.
The Province currently utilizes (250), (604) and (778), and the new area code will be (236). Until 1996, 604 was the only area code in British Columbia. At that time, 250 was introduced to serve the area outside the Greater Vancouver Area. In 2001, area code 778 and 10-digit dialing were introduced in the Greater Vancouver Area, before being extended across the province in 2008.
