Bradford West Gwillimbury, a town in south-central Ontario, in the County of Simcoe in the Toronto Census Metropolitan Area on the Holland River. West Gwillimbury takes its name from the family of Elizabeth Simcoe, née Gwillim.
The former Town of Bradford was amalgamated with portions of the former Townships of West Gwillimbury and Tecumseth to become the Town of Bradford West Gwillimbury on January 1, 1991.
Holland Marsh, a region of #9 humus soil, is located partly in Bradford West Gwillimbury. The town, along with the Township of King is the governing body responsible for the maintenance of the drainage system of this source of Canada’s produce supply. In 2007 a Holland Marsh Drainage System Joint Municipal Board was created in response to a crisis of maintenance of the Holland Marsh Drainage System.
The Holland River flows through the middle of the southernmost Holland Marsh polder and eventually flows out to Lake Simcoe. Geographically, the area is north of the Oak Ridges Moraine.
