Hey you 613ers (Wikipedia - 613 Area Code Details) and 705ers (Wikipedia - 705 Area Code Details), there are new Area Codes coming your way in March 2011.
Here's the story from CTV News:
Ontario, Quebec get new mobile area codes
Parts of Ontario and Quebec are getting new area codes to help meet the demand for more phone numbers, especially on mobile phones.
In Eastern Ontario, a new 343 area code will be available for new numbers in the territory covered by the 613 area code.
A new 249 area code will be introduced in the 705 region of Ontario starting next March.
