 John Street has had a major impact in shaping the community; the parallel Green Lane/14th Avenue east-west road allowance has never been fully opened and Leslie Street still diverts from the route laid out by the township survey to join Don Mills Road near the former easterly end of John Street.John Street is a four-lane arterial road between Woodbine Avenue and Bayview Avenue, and, due to the presence of Old Thornhill, a two-lane collector road between Bayview and Yonge Street.John Street currently serves to relieve traffic on Steeles Avenue, and Highway 7.
