Where & When?

Starting April 1, 2023, local 10-digit dialing will be introduced in Newfoundland & Labrador (709 area code), northern Ontario (807 area code) and the three exchanges of Yellowknife (including Dettah), Behchokǫ̀, and Whatì (867 area code). Residents will need to dial 10 digits – the area code followed by the seven-digit phone number – for all local calls. The introduction of 10-digit dialing is the result of a decision by the Canadian Radio-television and Telecommunications Commission (CRTC).

Key Dates

Starting April 1, 2023
Businesses and consumers can start dialing the area code followed by the 7-digit phone number for local calls. If the area code is not dialed, the caller may hear a reminder message before the call is completed.

Starting May 31, 2023
Ten-digit dialing will be mandatory: businesses and consumers will have to dial the area code followed by the 7-digit number for all local calls. If the 10-digit number is not dialed, the call will not be completed.

What is 10-Digit Local Dialing?

10-digit local dialing means that the caller must dial the area code (three digits) followed by the phone number (seven digits) for all local communications.

What will happen if residents and businesses dial a seven-digit number after this date?

A network announcement will remind them to use 10-digit dialing the next time. Because this message may disrupt data transmission (Internet, faxes etc.), it reinforces the importance of quickly adopting 10-digit dialing.
Starting May 31, 2023, all local calls will have to be preceded by the area code, otherwise they will not be connected.

Why must 10-digit dialing be used for local calls?

This dialing method will pave the way for the introduction of a new 3-digits special number 9-8-8 for mental health and suicide prevention.

How should a telephone number be written?

When written or printed, the 10-digit telephone number should be visually separated by dashes, spaces or periods in accordance with international standards (e.g., 709 123-4567 or 709-123-4567). The area code should not appear in parentheses since this may lead the caller to believe the area code is optional.

Can people continue to dial 9-1-1 in case of emergency?

Yes. The 9-1-1 emergency number, where available, will not change in any way and will still require only three digits.

Will long-distance calls be affected?

Long-distance calls will continue to be made in the same manner. Simply enter “1” followed by the 10-digit number.

Le 9-1-1 est-il toujours le numéro à composer en cas d’urgence ?

Oui. Le numéro d'urgence 9-1-1 ne change pas. Il comporte toujours trois chiffres seulement.

Si le « 1 » est composé par mégarde avant les 10 chiffres d’un numéro local, devra-t-on payer des frais d'interurbain ?

Non. L’équipement téléphonique reconnaîtra qu’il s’agit d’un numéro local et vous entendrez un message à cet effet.
