The 437 area code was introduced in March 2013 as an overlay to the existing 416 and 647 area codes in Toronto, Ontario. As the city grew rapidly in both population and business activity, the demand for new phone numbers began to outpace supply.

To address this, the Canadian Radio-television and Telecommunications Commission (CRTC) implemented the 437 area code to ensure a continuous availability of numbers without disrupting existing ones.

Unlike traditional area code splits, the overlay method allowed current users to keep their numbers while new users received the 437 prefix. This change also required mandatory 10-digit dialing for local calls within the region.

Since its launch, 437 has become widely adopted by mobile carriers, VoIP services, and businesses, supporting the ongoing growth of the Greater Toronto Area while maintaining a consistent communication infrastructure.
