The Toronto streetcar system is a network of eleven streetcar routes in Toronto, Ontario, Canada, operated by the Toronto Transit Commission (TTC). It is the third busiest light-rail system in North America. The network is concentrated primarily in Downtown Toronto and in proximity to the city's waterfront. Much of the streetcar route network dates from the second half of the 19th century. Three streetcar routes operate in their own right-of-way, one in a partial right-of-way, and six operate on street trackage shared with vehicular traffic with streetcars stopping on demand at frequent stops like buses. Since 2020, the network has operated using only low-floor streetcars, making it fully accessible.

Toronto's streetcars provide most of the downtown core's surface transit service. Four of the TTC's five most heavily used surface routes are streetcar routes. In , the system had a ridership of , or about per weekday as of .

History

Pre-TTC history (1861–1921)

The main predecessors of the TTC were: Toronto Street Railway (1861–1891) Toronto Railway Company (1891–1921) Toronto Civic Railways (1911–1921)

In 1861, the City of Toronto issued a thirty-year transit franchise (Resolution 14, By-law 353) for a horse-drawn street railway, after the Williams Omnibus Bus Line had become heavily loaded. Alexander Easton's Toronto Street Railway (TSR) opened the first street railway line in Canada on September 11, 1861, operating from Yorkville Town Hall to the St. Lawrence Market. At the end of the TSR franchise, the City government ran the railway for eight months but ended up granting a new thirty-year franchise to the Toronto Railway Company (TRC) in 1891. The TRC was the first operator of horseless streetcars in Toronto. The first electric car ran on August 15, 1892, and the last horse car ran on August 31, 1894, to meet franchise requirements.

There came to be problems with interpretation of the franchise terms for the City. By 1912, the city limits had extended significantly, with the annexation of communities to the north (1912: North Toronto) and the east (1908: Town of East Toronto) and the west (1909: the City of West Toronto—The Junction). After many attempts to force the TRC to serve these areas, the City created its own street railway operation, the Toronto Civic Railways (TCR) to do so, and built several routes. Repeated court battles forced the TRC to build new cars, but they were of old design. When the TRC franchise ended in 1921, the Toronto Transportation Commission was created, combining the city-operated Toronto Civic Railways lines into its new network.

Early TTC history (1921–1945) The TTC began in 1921 as solely a streetcar operation, with the bulk of the routes acquired from the private TRC and merged with the publicly operated Toronto Civic Railways. In 1923, the TTC took over the Lambton, Davenport and Weston routes of the Toronto Suburban Railway (TSR) and integrated them into the streetcar system.

In 1925, routes were operated on behalf of the Township of York (as Township of York Railway), but the TTC was contracted to operate them. One of these routes was the former TSR Weston route and the others were the TTC Oakwood and Rogers Road streetcar routes. The Weston streetcar route was replaced by electric trolley buses in 1948, while Rogers Road route was replaced by the 63 Ossington trolley bus route in 1974; ultimately diesel bus routes replaced the trolley buses in 1992.

In 1927, the TTC became the operator of three radial lines of the former Toronto and York Radial Railway. The TTC connected these lines to the streetcar system in order to share equipment and facilities, such as carhouses, but the radials had their own separate management within the TTC's Radial Department. The last TTC-operated radial (North Yonge Railways) closed in 1948.

Plans for abandonment (1945–1989) After the Second World War, many cities across North America and Europe began to eliminate their streetcar systems in favour of buses. During the 1950s, the TTC continued to invest in streetcars and the TTC took advantage of other cities' streetcar removals by purchasing extra PCC cars from Cleveland, Birmingham, Kansas City, and Cincinnati.

In 1966, the TTC announced plans to eliminate all streetcar routes by 1980. Streetcars were considered out of date, and their elimination in almost all other cities made it hard to buy new vehicles and maintain the existing ones. Metro Toronto chair William Allen claimed in 1966 that "streetcars are as obsolete as the horse and buggy". Many streetcars were removed from service when Line 2 Bloor–Danforth opened in February 1966.

The plan to abolish the streetcar system was strongly opposed by many people in the city, and a group named "Streetcars for Toronto" was formed to work against the plan. The group was led by Professor Andrew Biemiller and transit advocate Steve Munro. It had the support of city councillors William Kilbourn and Paul Pickett, and urban advocate Jane Jacobs. Streetcars for Toronto presented the TTC board with a report that found retaining the streetcar fleet would, in the long run, be cheaper than converting to buses. This combined with a strong public preference for streetcars over buses changed the decision of the TTC board.

The busiest north–south and east–west routes were replaced respectively by the Yonge–University and the Bloor–Danforth subway lines, and the northernmost streetcar lines, including the North Yonge and Oakwood routes, were replaced by trolley buses (and later by diesel buses). Two lines that operated north of St. Clair Avenue were also abandoned for other reasons. The Rogers Road route was abandoned to free up streetcars for expanded service on other routes. The Mount Pleasant route was removed because of complaints that streetcars slowed automobile traffic. Earlier, the TTC had contemplated abandonment because replacement by trolley buses was cheaper than replacing the aging tracks.

However, the TTC maintained most of its existing network, purchasing new custom-designed Canadian Light Rail Vehicles (CLRV) and Articulated Light Rail Vehicles (ALRV), with the first CLRV entering service in 1979. It also continued to rebuild and maintain the existing fleet of PCC (Presidents' Conference Committee) streetcars until they were no longer roadworthy.

Plans to assign route numbers to the streetcar lines, which had previously only carried route names, were announced in early 1978, and route numbers first came into use when the first CLRVs entered service in 1979. The PCC cars did not yet have route-number rollsigns, but they were later equipped with them, replacing the route-name signs, and route numbers began being displayed on PCC cars (on all routes) on February 4, 1980.

When Kipling station opened in 1980 as the new western terminus of Line 2 Bloor–Danforth, it had provision for a future streetcar or LRT platform opposite the bus platforms. However, there was no further development for a surface rail connection there.

In the early 1980s, a streetcar line was planned to connect Kennedy station to Scarborough Town Centre. However, as that line was being built, the Province of Ontario persuaded the TTC to switch to using a new technology called the Intermediate Capacity Transit System (now Bombardier Innovia Metro) by promising to pay for any cost overruns (which eventually amounted to over $100million). Thus, the Scarborough RT (later renamed Line 3 Scarborough) was born, and streetcar service did not return to Scarborough, instead stopping at the limits at Victoria Park Avenue.

Late 20th-century expansion (1989–2000)

The TTC returned to building new streetcar routes in 1989. The first new line was route 604 Harbourfront, starting from Union station, travelling underneath Bay Street and rising to a dedicated centre median on Queen's Quay (along the edge of Lake Ontario) to the foot of Spadina Avenue. This route was lengthened northward along Spadina Avenue in 1997, continuing to travel in a dedicated right-of-way in the centre of the street, and ending in an underground terminal at Spadina station. At this time, the route was renamed 510 Spadina to fit with the numbering scheme of the other streetcar routes. This new streetcar service replaced the former route 77 Spadina bus and, since 1997, has provided the main north–south transit service through Toronto's Chinatown and the western boundary of University of Toronto's main campus, the St. George campus. The tracks along Queen's Quay were extended to Bathurst Street in 2000 to connect to the existing Bathurst route, providing for a new 509 Harbourfront route from Union station to the refurbished Exhibition Loop at the Exhibition grounds, where the annual Canadian National Exhibition is held during the summer.

21st century (2001–present) By 2003, two-thirds of the city's streetcar tracks were in poor condition as the older track was poorly built using unwelded rail attached to untreated wooden ties lying on loose gravel. The result was street trackage falling apart quickly requiring digging up everything after 10 to 15 years. Thus, the TTC started to rebuild tracks using a different technique. With the new technique, concrete is poured over compacted gravel, and the ties are placed in another bed of concrete, which is topped by more concrete to embed rail clips and rubber-encased rails. The resulting rail is more stable and quieter with less vibration. The new tracks are expected to last 25 years after which only the top concrete layer needs to be removed in order to replace worn rails.

Route 512 St. Clair was rebuilt to restore a separated right-of-way similar to that of the 510 on Spadina Avenue, to increase service reliability and was completed on June 30, 2010.

On December 19, 2010, 504 King streetcar service returned to Roncesvalles Avenue after the street was rebuilt to a new design, which provided a widened sidewalk "bumpout" at each stop to allow riders to board a streetcar directly from the curb. When no streetcar is present, cyclists may ride over the bumpout as it doubles as part of a bike lane.

On October 12, 2014, streetcar service resumed on 509 Harbourfront route after the street was rebuilt to a new design that replaced the eastbound automobile lanes with parkland from Spadina Avenue to York Street. Thus, streetcars since then run on a roadside right-of-way immediately adjacent to a park on its southern edge.

The Toronto Transit Commission eliminated all Sunday-only stops on June 7, 2015, as these stops slowed down streetcars making it more difficult to meet scheduled stops. Sunday stops, which served Christian churches, were deemed unfair to non-Christian places of worship, which never had the equivalent of a Sunday stop. Toronto originally created Sunday stops in the 1920s along its streetcar routes to help worshippers get to church on Sunday for religious services.

The first two Flexity Outlook streetcars entered service on route 510 Spadina, on August 31, 2014; at the same time, all-door boarding and proof-of-payment (POP) was introduced on all 510 Spadina streetcars. Fare payments by Presto on the Flexity cars was introduced on November 30, 2014. On November 22, 2015, the TTC started to operate its new fleet of Flexity Outlook streetcars from its new Leslie Barns maintenance and storage facility.

On December 14, 2015, the TTC expanded Presto, POP and all-door loading to include all streetcars on all routes. All streetcar passengers are required to carry proof that they have paid their fares such as a single-ride ticket; a paper transfer; or a tapped-in Presto card while riding. At the same time, the TTC also activated the option for customers to purchase single-ride tickets using debit or credit cards on the fare vending machines on Flexity streetcars.
