High Quality Content by WIKIPEDIA articles! Highway 407, officially known as the 407 Express Toll Route (ETR), is a privately operated 400-series highway and tollway in the Canadian province of Ontario. Despite being included as part of the 400-series network, Highway 407 is not part of the provincial highway network. It begins at the junction of the Queen Elizabeth Way (QEW) and Highway 403 in Burlington, and travels 107.2 km (66.6 mi) northeast and east to its present terminus at Highway 7 and Brock Road (Durham Regional Road 1) in Pickering. Plans are currently underway to extend the highway further east through Durham Region to Highway 35/115 near Orono as a provincially maintained highway.
