Streetcar route in Toronto, Canada

504 King (304 King during overnight periods) is an east–west Toronto streetcar route in Ontario, Canada. It serves King Street in Downtown Toronto as well as Broadview Avenue on the east end and Roncesvalles Avenue on the west end of the line. The route consists of two overlapping branches: 504A between Line 2 Bloor–Danforth's Dundas West station and Distillery Loop, and 504B between Broadview stationalso on Line 2and Dufferin Gate Loop. The two branches overlap on King Street between Dufferin and Sumach streets, both passing St. Andrew station and King station on subway Line 1 Yonge–University. In 2022, with almost 13.5 million annual boardings, 504 King was the busiest streetcar line in Toronto. (In 2019, prior to the drop in ridership due to the COVID 19 pandemic, there were almost 29.7 million annual boardings.)

Between 2009 and 2011, However, the platform height at the bumpouts was incompatible with the wheelchair ramp on the low floor Flexity Outlook streetcars that were introduced in 2018 on the 504 King route. Thus, no stops along Roncesvalles Avenue between Queen Street and Dundas Street West were accessible. as of 2023, the bumpout heights had still not been adjusted.

On July 1, 1923, as part of a reorganization of streetcar routes, the King streetcar route acquired its current U shape. The west end of the line was at the Vincent Loop, located near the northeast corner of Dundas Street West and Bloor Street West, across the street from today's Dundas West station. The east end of the line was at the Erindale Loop, located at the northeast corner of Broadview Avenue and Erindale Avenue, on the north side of today's Broadview station. From July 1, 1923, to July 13, 1951, some King streetcars provided rush hour service along Bloor Street West between Dundas Street West and Jane Loop. The TTC ended this service due to declining ridership. Starting July 16, 1951, all King service turned back at Vincent Loop. in favour of ordering brand new, longer Flexity Outlook vehicles. Starting June 19, 2016, a new route – 514 Cherry – was created to supplement 504 King service on King Street between Dufferin and Sumach streets. The 514 route increased capacity along the King Street corridor to address the growing downtown ridership. It also addressed accessibility concerns through its use of the low floor Flexity Outlook streetcars. From December 2, 2017, the TTC assigned a minimum of two low floor accessible Flexity Outlook streetcars on 504 King to handle weekday overcrowding, as the King Street Pilot Project improved service performance and made the service more popular. On January 2, 2018, Flexity Outlook streetcars were introduced on the 504 King route. By January 6, 2019, the 504 King route was fully served by Flexity Outlook streetcars. Thus, the TTC designated the route as accessible except along Roncesvalles Avenue where the platform height still needed to be adjusted to allow deployment of the Flexity ramp. On May 9, 2021, the intersection of King Street, Queen Street, The Queensway and Roncesvalles Avenue (KQQR) closed due to various construction projects in the area such as track replacement, reconfiguration of the KQQR intersection, adjusting the height of streetcar loading platforms along Roncesvalles Avenue and upgrades to water, sewer and electrical infrastructure. Initially, 504A King service was diverted to Dufferin Gate Loop instead of Dundas West station. On October 1, 2022, both branches of the 504 streetcar were diverted to Exhibition Loop to accommodate the replacement of the streetcar junction at King and Shaw Streets. With the completion of work at King and Shaw, 504A streetcars diverted again to Dufferin Gate Loop on December 9, 2022, but with 504B streetcars diverting to Wolseley Loop. On February 12, 2023, 504 service was cut back to Bathurst Street in order to convert the overhead wire west of Bathurst for pantograph operation; 504A cars were diverted to Exhibition Loop and 504B to Wolseley Loop. On March 26, 2023, the 504 King route diverted to Queen Street between Shaw Street and the Don River to convert the remaining overhead wire on King Street. On May 1, 2023, streetcars returned to King Street, operating between Dufferin Gate loop and Broadview station, after TTC crews worked the previous night to finish the conversion of the overhead for pantograph operation. On May 7, 2023, streetcar service resumed on Roncesvalles Avenue, ending two years of bus replacement on the west end of the 504 King route.

From 1987 to 1992, the Blue Night Network included the 304 King route, which provided overnight service along the length of the 504 King daytime route. The 304 route was eliminated in February 1992, with the Broadview and Roncesvalles segments replaced by portions of other Blue Night bus routes; however, King Street remained unserviced directly until September 6, 2015, when the 304 King was restored as part of a $95 million investment from Toronto City Council. Currently, overnight service operate every 30 minutes between Broadview and Dundas West stations via Broadview Avenue, King Street, and Roncesvalles Avenue.
