40 Junction (1968-2019)

A History of the 40 Junction Trolley Bus




7 days a week, 18 hours a day

This route, operating from Dundas West station on the BLOOR DANFORTH SUBWAY, northwest via Dundas to an off-street loop on the northwest corner of Dundas Street and Runnymede Avenue (the city limits of Toronto at the time) used to be served by an extension of the DUNDAS streetcar. When the Bloor subway opened its first phase between Keele and Woodbine stations, the Dundas streetcar continued to operate north of Bloor, until a conversion to trolley coach could take place. The 40 JUNCTION bus opened for service on May 11, 1968 — the day the Bloor-Danforth subway was extended west from Keele to Islington and east from Woodbine to Warden.

The operating characteristics of the 40 JUNCTION trolley bus all descended from its streetcar parent. It operated out of Dundas West station, seven days a week. Although it ran less frequently than its south-of-Bloor parent, the Junction bus retained the streetcar’s night service until February 8, 1987, when the service was taken over the next day by the new 313 JANE VIA DUNDAS BLUE NIGHT bus, operating from Dundas West station via Dundas and Jane to Steeles Avenue.

Looking at a map of the TTC’s services in the area, one may wonder why service on Dundas north of Bloor was split between this route and the 30 LAMBTON bus, with 30 LAMBTON running from High Park station via High Park to Kipling station. The two services duplicate service for a short stretch of Dundas Street between High Park and Runnymede. Even after the elimination of trolley bus service on 40 JUNCTION, the split continues to this day.

However, the urban development of the area that kept the DUNDAS streetcar separate from the suburban services beyond continued to play itself out long after the streetcars disappeared. The Toronto city limits ran down Runnymede, and the territory west of Runnymede was controlled by the Borough of York. The DUNDAS streetcar fostered higher density development on Dundas east of Runnymede, in a neighbourhood now known as the Toronto Junction. West of Runnymede, development occurred later and at lower densities. This justified higher frequencies for the 40 JUNCTION trolley bus than for bus services beyond, while at the same time limiting any enthusiasm for an extension of trolley bus wires west of Runnymede.

Also, until 1972, the TTC’s Zone 1/Zone 2 fare boundary passed through Runnymede loop, which meant that keeping the transit services separate made it easier to manage fare collection. If you wanted to travel from Dundas west of Runnymede to Dundas east of Runnymede, you had to pay a second fare anyway, so a transfer to a second bus was justified. Also, even though the 30 LAMBTON bus straddled both sides of the fare boundary, it fed into the BLOOR-DANFORTH SUBWAY at High Park, where one had to show a valid transfer to continue one’s journey, limiting the possibilities of fare evasion.

The JUNCTION trolley bus did not have any short-turn loops or branches, and since its conversion to diesel buses on August 3, 1991 (the first route of the system to be converted, likely due to a shortage of usable equipment), there have been no changes to its routing. Intriguingly, there is a chance that the bus route could be reconverted into streetcar operation. At some point, the TTC plans to extend the 512 ST CLAIR streetcar west from Gunns Loop to the current Junction loop at Dundas and Runnymede. When this happens, the TTC might convert the 40 JUNCTION route to streetcars in order to provide a second connection between its St. Clair tracks and the rest of the system, dramatically reducing the deadhead time of the St Clair streetcars entering and leaving service from Roncesvalles Carhouse. This was eventually changed after the Junction Area Study took place in 2017, with the route renamed and extended to Kipling station as the 40 JUNCTION-DUNDAS WEST bus, thus rendering the plan moot.
