The current Cannock Extension Canal is a 1.8-mile (2.9 km) canal in England. It runs from Pelsall Junction on the Wyrley and Essington Canal, north to Norton Canes Docks and forms part of the Birmingham Canal Navigations. Historically, it ran to Hednesford, and served a number of collieries, which provided the main traffic. It opened in 1863, and the northern section closed in 1963, as a result of mining subsidence.
