• 236, 250, 604 and 778 in British Columbia;
• 418 and 581 in Quebec;
• 506 in New Brunswick; and
• 709 in Newfoundland and Labrador.

Since New Brunswick and Newfoundland and Labrador currently have 7-digit local dialing, the introduction of new area codes in these provinces will require a transition to 10-digit local dialing. This will ensure that all local calls are routed to the correct area code.

The CRTC is establishing relief planning committees to evaluate various options and make recommendations.
