On April 3, 2006, the station celebrated its 40th anniversary. It began airing its digital signal on UHF channel 58 in high definition in 2008. WJET's broadcasts became digital-only, effective June 12, 2009. It is carried on cable in London, St. Thomas and other communities in Ontario, Canada near Lake Erie. In recent years, the station has been bumped to high dial positions on cable systems in those locations. WJET-TV was once available on cable in the Hamilton, Niagara, and Grand River areas but was dropped by the early 2000s.
