where does the 407 start in the east
Ontario Highway 407 King's Highway 407 (pronounced "four-oh-seven") is a tolled 400-series highway in the Canadian province of Ontario. Comprising a privately leased segment as well as a publicly owned segment, the route begins in Burlington and travels through the Greater Toronto Area (GTA) suburbs of Oakville, Mississauga, Brampton, Vaughan, Markham, Pickering and Whitby before ending in Clarington north of Bowmanville. The segment between Burlington and Brougham in Pickering is leased to and operated by the 407 ETR Concession Company Limited and is officially known as the 407 Express Toll Route (407 ETR). It begins at the junction of the Queen Elizabeth Way (QEW) and Highway 403 in Burlington, and travels 107.9 km (67.0 mi) across the GTA to Brock Road in Pickering. East of Brock Road the freeway continues east as Highway 407 East (Highway 407E), a toll route operated by the provincial government, for 30.8 km (19.1 mi) to Taunton Road in Clarington. Highway 407 is the first electronically operated toll highway opened in the world; there are no toll booths along the length of the route. Distances are calculated automatically using transponders or licence plates, which are scanned at entrance and exit points. Major interchanges along the route include the QEW, Highway 403, Highway 401, Highway 410, Highway 427, Highway 400, Highway 404, and Highway 412.
