Weston Road is a north–south street in the west end of Toronto and western York Region in Ontario, Canada. The road is named for the former Village of Weston, which was located near Weston Road and Lawrence Avenue West. Route description In the south, Weston Road begins at St. Clair Avenue opposite the north end of the southern leg of Keele Street. The southernmost 55 metres of the street north of St. Clair, where the roadway diverted to the west off its straight baseline, was formerly a part of Keele, which officially breaks here and is cut off from its northern section. Weston Road formerly began at the diversion, but this stretch of Keele St. was redesignated as part of Weston Road in 2006. Weston Road then travels diagonally across the general arterial road grid in a northwesterly direction to Highway 401, passing through Mount Dennis at Eglinton Avenue, and Weston north of Lawrence Avenue. North of the 401, it becomes a normal grid road and runs parallel to Highway 400 to Steeles Avenue and into Vaughan in York Region. Most of Weston Road is a four-lane principal arterial road through residential areas, except for the northern section which is mostly industrial. The speed limit south of Finch Avenue is 50 km/h (30 mph), which increases to 60 km/h (35 mph) between Finch and Steeles. North of the Toronto city limits at Steeles Avenue, Weston Road enters York Region, where it is designated as York Regional Road 56. It passes through the two western municipalities of York Region, Vaughan in the south and King in the north. The speed limit through the urbanized parts of Vaughan is 60 km/h (35 mph), while the limit is 80 km/h (50 mph) in rural Vaughan and King Township. The northern terminus of the road is at Highway 9 in the Holland Marsh. History Weston Road was first laid out in the first decade of the 1800s to connect Dundas Street to the village of Weston. This followed the route of what is today Old Weston and (west of Watts Avenue) Rogers Roads, then the route of the current Weston Road north to Weston. The old routing was renamed in 1948. Between 1810 and 1820, it was extended north to Vaughan Township by following Sixth Line West. In 1841, the route was bought by private interests and it became the "Weston Plank Road", a
