Close to 8 years since the activation of area code 365, the densely populated Golden Horseshoe region to the West and NW of lake Ontario (not including the city of Toronto) is again in need of a relief NPA. The new area code 742 was therefore activated today, October 16, 2021 to cover the aforementioned geographic area, forming overlay complex 905/289/365/742 which serves around 20% of the entire Canadian population.
