List of Ontario area codes
From Wikipedia, the free encyclopedia
This is a list of area codes in the province of Ontario:
- 226: Most of Southwestern Ontario; overlays with 519
- 289: The Niagara Peninsula, Hamilton, Oshawa, and the suburban Greater Toronto Area; overlays with 905
- 416: Toronto; overlays with 647
- 519: Most of Southwestern Ontario; overlays with 226
- 613: Ottawa, Kingston, and surrounding Southeastern Ontario
- 647: Toronto; overlays with 416
- 705: Most of Northeastern and Central Ontario
- 807: Most of Northwestern Ontario
- 905: The Niagara Peninsula, Hamilton, Oshawa, and the suburban Greater Toronto Area; overlays with 289
Area code 343 has been reserved for an overlay with 613 in eastern Ontario, beginning in 2010.
Relief is planned by 2011 in the 705 area. It could be a split or overlay, either with a new area code or 807 expanding. Since it has many decades of additional capacity left, it is possible that 807 may expand and possibly overlay area code 705 while keeping its own code by itself in its area, similar to area code 321 over 407 in Florida.[1]
