905er

A "905er" is a colloquial term used to refer to a resident of the 905 area code in Ontario, Canada. The 905 area code primarily serves the Greater Toronto Area (GTA) surrounding the city of Toronto, which is covered by area code 416 and 579. This includes municipalities such as Mississauga, Brampton, Hamilton, Oakville, Burlington, and Vaughan, among others. The term is often used to distinguish people living in these suburban areas from those who live in Toronto proper.

The 905 area code was established in 1997 as an overlay to the 416 area code, which had been in use for decades. The division was necessary due to the rapid population growth in the suburban regions of the GTA, leading to an exhaustion of available phone numbers within the 416 area code. The introduction of the 905 code allowed for continued expansion of telecommunication services in the region. Over time, the term "905er" has become part of the local lexicon, reflecting a distinct identity associated with the suburban communities of the GTA. It is generally used in informal conversation and does not carry any official or derogatory connotations.
