Community

Lake Wilcox is a local community located within Oak Ridges. The local community has an elementary school; Lake Wilcox elementary school, the Lake Wilcox Community Centre, as well as a number of local parks. Lake Wilcox and Brickworks parks are the most popular. The local community has come together through a number of tragedies, including the death of a local mother, Terri Callaway on North Lake Road, and two local teens who accidentally drowned in the lake in 2008. The now defunct Lake Wilcox Brewing Co., located in Vaughan, was named after the lake.


History

The lake was recorded as "Lake Wilcocks" on an 1878 map in the ''Illustrated historical atlas of the county of York and the township of West Gwillimbury & town of Bradford in the county of Simcoe, Ont.'' Housing developments began to boom around Lake Wilcox in the 1950s. Lake Wilcox, as a part of the annexation of Oak Ridges, became a part of Richmond Hill in 1971. The suburban housing developments continued until the mid to late 1980s. The developments affected the forests of the Oak Ridges Moraine which supplies water to the GTA, which caused environmental damage to Toronto. There were protests against the clear-cutting of forests of the Oak Ridges Moraine. In about 2001, Bayview began to expand to connect with the rest of Bayview. In 2002, the housing developments stopped.
