Are you affected by the new area codes?

Only eastern and northern Ontario and the region surrounding Montréal will be receiving new area codes.

  • Starting May 17, 2010, the 343 code will be introduced gradually in the region served by the 613 code once there are no 613 numbers left.
  • Starting August 21, 2010, the 579 code will be introduced gradually in the region served by the 450 code once there are no 450 numbers left.
  • Starting March 19,2011, the 249 code will be introduced gradually in the region served by the 705 code once there are no 705 numbers left.

Introducing a new area code within a region already served by another code creates only minor changes. Adding an area code using the overlay method does not cause any numbers to change for current customers. And local calling areas also remain the same.

  • Only new telephone lines are affected by this addition.
  • Existing numbers keep the same area code and are not changed in any way.
  • Local calling areas remain the same.
  • The 9-1-1 emergency number remains a three-digit number throughout the area.
