Area code 905 is an integral part of the telephone numbering plan in Canada, specifically in the province of Ontario. Geographical Coverage: Area code 905 serves the regional municipalities surrounding the city of Toronto, including the Niagara Region, Hamilton, and parts of the Greater Toronto Area such as Mississauga, Brampton, Vaughan, and Oshawa. This area is known for its diverse suburban communities and economic activity. Establishment and Overlays: The 905 area code was established in 1993, following a split from the 416 area code. Due to the rapid growth in the demand for telephone numbers, primarily because of the proliferation of cell phones and internet services, an overlay area code, 289, was introduced in 2001. Later, another overlay, 365, was added in 2013. Cultural and Economic Significance: The region served by area code 905 is a key economic zone in Ontario, featuring a mix of industrial, commercial, and residential areas. It includes some of Canada's fastest-growing cities and is known for its cultural diversity, with a large immigrant population contributing to the area's vibrant community and economic life. In conclusion, area code 905, along with its overlay codes 289 and 365, represents a vital telecommunication zone in Ontario, reflecting the rapid growth and dynamic nature of the regions surrounding Toronto. Its implementation mirrors the evolving telecommunications needs and the demographic changes of this densely populated area of Canada.
