 Between Highway 404 and Woodbine Avenue, all zonings are industrial.John Street forms a link in what is otherwise the first concession road north of Steeles Avenue, with 14th Avenue, Centre Street, and the portion of Highway 7 west of Dufferin Street.However, due to the aforementioned presence of Old Thornhill and the desire to eliminate a jog in Highway 7 by the Province of Ontario, the road alignment was never developed into a single, continuous cross-region arterial.
