The 503 Kingston Rd is an east–west Toronto streetcar route in 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 along Kingston Road and shares much of its track with the 501 Queen and 504 King. Originally a rush-hour service, the route was upgraded in September 2019 to run weekdays excluding evenings after the consolidation of 502 Downtowner service into this route. Effective July 30, 2023, route 503 started running all day and all evening, seven days per week.
Starting at the Bingham Loop on Victoria Park Avenue, the 503 runs southwest on Kingston Road then turns west along Queen Street. At the Queen Street Viaduct bridging the Don River, it then turns southwest along King Street, enters the King Street Transit Priority Corridor but leaves it by running south of King Street via Church, Wellington and York Streets. In the vicinity of St. Andrew station, the 503 returns eastbound on King Street.
Since 2016, the route has had two variations depending on whether streetcars or temporary replacement buses serve the route. If buses serve route 503, they run as described above. However, if streetcars serve the route, they continue along King Street to Spadina Avenue before turning back east via the Charlotte Loop.
Two streetcar routes, 503 Kingston Rd and 502 Downtowner, serve Kingston Road. Route 502 Downtowner was originally named "Kingston Rd" while 503 Kingston Rd was originally named "Kingston Rd Tripper". The Kingston Rd route (today's 502 Downtowner) ran from the McCaul Loop to the Birchmount Loop until 1954 when it was cut back to the Bingham Loop. By 1968, the rush-hour route Kingston Rd Tripper (today's 503 Kingston Rd) was appearing in TTC Ride Guides. "Tripper" here means a rush-hour variant of a base route which in this case was the Kingston Rd route (today's 502 Downtowner).
In 1973, the Kingston Rd route was renamed to "Downtowner" (today's 502 Downtowner) with a route extension to Bathurst station that was revoked in 1984. Also in 1973, with the renaming of "Kingston Rd" to "Downtowner", the Kingston Rd Tripper became simply "Kingston Rd" and ultimately the 503 Kingston Rd.
Until December 29, 2015, the 503 Kingston Rd route operated with streetcars from Bingham Loop (Victoria Park and Kingston Road) to York Street (via King, Church and Wellington Streets),[3] after which temporary replacement bus service served the route also from Bingham Loop to York Street.[4] Starting June 19, 2017, streetcars resumed operating on the route but to Spadina Avenue (Charlotte Loop) instead of York Street as the western terminal.[5]
From July 31, 2017, until February 16, 2018, buses replaced streetcars on the 503 Kingston Rd route due to a shortage of streetcars resulting from the late delivery of the new Bombardier Flexity Outlook streetcars.[6] The buses operated from Bingham Loop to York Street.[7]
On February 20, 2018, streetcars returned to route 503 Kingston Rd running from Bingham Loop to Spadina Avenue. However, the roles of routes 502 Downtowner and 503 Kingston Rd were reversed. Prior to that date, route 502 provided base workday service supplemented by route 503 in the rush hours. Since that date, route 503 provides base service while route 502 provides rush-hour-only service. These changes were to support the King Street Pilot Project which resulted in increased ridership along downtown King Street. However, effective September 2, 2018, these changes were reversed, but 503 Kingston Rd continued to operate with streetcar service west to Spadina Avenue.
On January 7, 2019, the 503 route returned to shuttle bus operation to accommodate construction along Wellington Street. Buses used York street as the western terminal.[8] [9] Effective September 3, 2019, the 502 Downtowner service was suspended and replaced with the 503 Kingston Rd service to accommodate some construction projects. Route 503 service was upgraded to operating weekdays excluding evenings instead of just during rush hours.[10] [11] The construction projects ended in November 2019; however, the consolidation of Kingston Road service into 503 Kingston Rd remained in effect.[12]
In March 2020, the COVID-19 pandemic resulted in a loss of ridership on the TTC. As a result, on March 24 the TTC shortened the 503 Kingston Rd route to run only along Kingston Road between Bingham Loop and Woodbine Loop. Then, effective May 11, the 22A Coxwell bus replaced the remainder of the 503 route full-time
On June 22, 2020, streetcar service returned to the route, running from Bingham Loop to Spadina Avenue (Charlotte Loop). Service was provided by the low-floor, accessible Flexity Outlook streetcars. Starting September 4, 2022, 503 streetcars were diverted to Bathurst Street (Wolseley Loop).[13] Effective November 21, 2022, the TTC scheduled buses to replace streetcars on the route to allow upgrades to the overhead wires for pantograph operation. Replacement buses operated from Bingham Loop to York Street.[14]
On May 7, 2023, route 503 Kingston Rd was suspended and replaced partially and temporarily with a diversion of the 505 Dundas streetcar. Unlike the 503 route, the 505 diversion would serve Kingston Road both day and evening, seven days per week. From Dundas Street, the 505 streetcar would divert south on Broadview Avenue, east on Queen Street and Kingston Road, terminating at Bingham Loop.[15] The reason for the 505 diversion was the rebuilding of the streetcar loop at Broadview station and construction work on Broadview Avenue north of Gerrard Street.[16]
Effective July 4, 2023, the TTC reinstated the 503 route using replacement buses running between Bingham Loop and York street until 8:00 pm daily. After 8:00 pm, the 505 Dundas streetcar would replace the 503 bus along Kingston Road.[17] Effective July 30, 2023, 503 buses replaced 505 streetcars in the evening along Kingston Road with the result that the 503 route would provide service all day and all evening, 7 days per week between Bingham Loop and York Street.[18]
On October 8, 2023, streetcars replaced buses on route 503, operating again to Spadina Avenue (Charlotte Loop). Although the downtown loop via Church, Wellington and York Streets opened on the same day, the TTC temporarily assigned a diversion of the 501 Queen route instead of 503 to this loop.[19]
