Ontario area codes – a new one will be added this fall

The province of Ontario will receive a new area code this fall.

The growing demand for telephone numbers made it necessary to introduce a new area code. To meet this demand, a new area code will be introduced in southern Ontario this fall.

The area code 742 will be released on October 16 and will be phased in gradually in areas currently served by area codes 905, 289, and 265.
