Ajax (2006 population 93,104) is a town located in the Golden Horseshoe of Southern Ontario, Canada. The town is named for the HMS Ajax a Royal Navy cruiser that served in World War II. Ajax is a part of the Greater Toronto Area and the Regional Municipality of Durham. It is approximately 25 kilometers (16 mi) east of Toronto on the shores of Lake Ontario and is bordered by the city of Pickering to the west and to the north and the Town of Whitby to the east.

Today, Ajax is commonly considered part of the Greater Toronto Area, in the eastern part of the Golden Horseshoe region. As is true for most suburban areas in the Greater Toronto Area, Ajax has grown considerably since the 1980s. What was once a small town mostly surrounded by agricultural areas has increasingly become a bedroom community to Toronto and its environs. Many residents commute to work in Toronto or other municipalities in Durham Region. From Wikipedia, the free encyclopedia.
