The 503 Kingston Rd (temporarily replaced by shuttle buses as of fall 2016) is an east-west streetcar route in Toronto, Ontario, Canada, operated by the Toronto Transit Commission. The 503 Kingston Rd travels on a route to the downtown financial district from the Bingham Loop and operates in the rush hour only with a 12-minute service frequency. The route shares much of its track with the 501 Queen, 504 King and the 502 Downtowner.
Starting at the Bingham Loop on Victoria Park Avenue, the 503 runs southwest on Kingston Road then turns west along Queen Street. At the bridge over the Don River, it then turns southwest going along King Street and continues west to Church Street. It then goes south again to Wellington Street where it continues west to York Street. It then turns north and returns east along King Street, Queen Street and Kingston Road.
The Kingston Road line only travels over a short section of Kingston Road and does not extend into Scarborough, but used to extend as far as the Birchmount Loop, on Birchmount Road.
More recently, as of fall 2016 the route has been operated using only supplementary buses due to a streetcar shortage.
