New 548 area code coming to southwestern Ontario, plus 825 in Alberta

The increasing demand for new telephone numbers in southwestern Ontario has caused the CRTC and the Canadian Numbering Administrator to take quick action. Apparently numbers with the 519 and 226 area codes are expected to run out by September 2015. Coming to the rescue is area code 548, who’ll go live on June 4th, 2015. This region includes cities such as London, Sarnia, Kitchener-Waterloo and Brantford.

Update: Alberta will also see the new area code 825 go live on April 9, 2016.
