The lake is named after William Willcocks, who was a merchant and became mayor of Cork, Ireland in 1793.[3][4] Willcocks and his family moved to Upper Canada, where his cousin Peter Russell became interim administrator after the departure of John Graves Simcoe in 1796.[3] Willcocks "was an active land speculator" who acquired significant holdings in Upper Canada, including 800 acres (3.2 km2) surrounding the lake.[3] The name of the lake was originally Lake Willcocks, but it was corrupted over time to its present spelling.[3]

Circa 1920s

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.[7]

Housing developments began to boom around Wilcox Lake 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 did not continue until the mid to late 1980s. The developments affected the forests of the Oak Ridges Moraine which supplies water to the GTA. Which would cause environmental damage to Toronto. It continued for about two years. 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.


Wilcox Lake is part of the Humber River drainage system, draining into the East Humber River. The drainage basin of the lake covers 260 hectares. The maximum depth of the lake is 17.4 meters.[1]

Wetlands complexEdit

Wilcox Lake, Lake St. George, Swan Lake and Haynes Lake and their associated marshes, swamps and forests form a large wetland designated as a Provincially Significant Wetland.[8] The total complex has some ninety individually identified wetlands, covering 102 hectares, of which 57% is classified as swamp, 39% as marsh and 4% as bog.


Beginning in 1997, the town of Richmond Hill undertook a project to restore the lake's condition, which had degraded because of pollution and development. Septic systems which had previous drained into the lake were connected to sewers and lake lungs were installed to increase oxygenation of the water. High phosphorus levels in the lake remain problematic.[9]
