History & Cultural Notes

Sudbury's Big Nickel, a nine-metre replica of a 1951 Canadian five-cent piece erected in 1964 beside the Dynamic Earth science centre, stands as one of the region's most recognizable landmarks. It sits within the numbering territory now served in part by area code 683, a code that traces a longer bureaucratic history than most.

Area code 705 was created in 1956 from portions of the 613 and 519 numbering plan areas, covering most of Ontario north and west of the Golden Horseshoe, and was reduced in extent in 1962 when 807 split off to serve the northwest. As the territory's number supply tightened, an overlay code, 249, was approved and put into service on March 19, 2011, introducing mandatory ten-digit local dialing. A third overlay, 683, was reserved in February 2017 and finally activated on June 18, 2022, per a CRTC decision, to relieve projected exhaustion of the combined 705/249 supply. It is a distributed overlay, meaning new numbers anywhere in the territory may receive 705, 249, or 683 with no geographic distinction between them.

Beyond Greater Sudbury, the plan area reaches Barrie, North Bay, Sault Ste. Marie, Peterborough, and Timmins. Its economy centers on mining and mineral processing, forestry, steel manufacturing in Sault Ste. Marie, cottage-country tourism, and health care and education.
