Southwestern Ontario will soon have a new area code to go along with 226 and 519.
The new code is intended to meet the continuously growing demand for new telephone numbers in the region which stretches from Windsor, to Guelph, to Tobermory.
The new code, 548, will be available starting June 4, of 2016.
It will create millions of additional phone numbers without affecting existing numbers.
"The introduction of a new area code creates millions of additional telephone numbers without affecting existing numbers," said Glen Brown, spokesperson for the Canadian Numbering Administrator. "It is part of today's reality throughout North America and demonstrates the flexibility and growth potential of Canadian communications networks."
