High Quality Content by WIKIPEDIA articles! St. Clair Avenue is a major east-west street in Toronto, Ontario, Canada. It was laid out in the late eighteenth century by the British as a concession road (the Third Concession), 2 km (1.25 mi) north of Bloor Street and 4 km (2.5 mi) north of Queen Street. St. Clair Avenue has two sections. The western section extends from Moore Park in the east to Scarlett Road in the west, a distance of approximately 10 kilometres (6.2 mi). An eastern section picks up on the far side of the Don Valley at Taylor Creek Park, extending for 7 kilometres (4.3 mi) to Kingston Road. Like all streets in Toronto which cross Yonge Street, St. Clair is divided into separate East and West sections, each with its own street numbers beginning at Yonge Street. Unlike other concession roads in Toronto, St. Clair does not extend west into Etobicoke.
