New area codes in Canada

The introduction of new area codes is the result of decisions by the Canadian Radio-Television and Telecommunications Commission (CRTC).

The growing demand for communications services has increased the requirement for phone numbers in several regions across Canada.

When phone numbers start to run out in certain areas, new area codes are created to meet demand. Adding a new area code enables more than seven million new phone numbers to be created!

  • Starting November 21, 2020, the new area code 428 will be introduced in New Brunswick, currently served by area code 506.
  • Starting May 20, 2022, the new area code 879 will be introduced in Newfoundland and Labrador, currently served by area code 709.

New area codes have been successfully introduced in Canada to manage a growing shortage of telephone numbers in the following areas:

  • 672 in British Columbia (May 2019)
  • 367 in the 418/581 area in Québec (November 2018)
  • 548 in the 519/226 area in Ontario (June 2016)
  • 825 in Alberta (April 2016)
  • 782 in Nova Scotia and Prince Edward Island (November 2014)
  • 236 in British Columbia (June 2013)
  • 639 in Saskatchewan (May 2013)
  • 365 in the 905/289 area in Ontario (March 2013)
  • 437 in Toronto (March 2013)
  • 431 in Manitoba (November 2012)
  • 873 in the 819 area in Québec (September 2012)
  • 249 in the 705 area in northern Ontario (March 2011)
  • 579 in the 450 area in Québec (August 2010)
  • 343 in the 613 area in Ontario (May 2010)
  • 581 in the 418 area in Québec (September 2008)
  • 587 in the 403/780 area in Alberta (September 2008)
  • 438 in the 514 area in Montréal (November 2006)
  • 226 in the 519 area in Ontario (October 2006)
  • 778 in the 604/250 area in British Columbia (November 2001)
  • 289 in the 905 area in Ontario (June 2001)
  • 647 in the 416 area in Toronto (March 2001)

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 existing 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
  • For your local calls, you will always enter 10 digits (area code + local number)
