Service Reliability on 70 O’Connor: September 2021

This article continues a series reviewing service quality on some of the TTC’s shorter routes.


The O’Connor bus runs north from Coxwell Station and branches into a lopsided Y-shaped route. One branch, the 70A/B, goes north via O’Connor to Eglinton while the other, 70C, goes to Warden Station via St. Clair. The Eglinton service loops north of Eglinton except late evenings weekdays and Sundays.

This service design was changed in October so that all Eglinton trips operate as 70A, and the 70B Eglinton Square turnback has been dropped. However, for this analysis, it was still operating. For that reason, the screenline for southbound headways on this branch is set south of the common point for both the 70A and 70B services.

Two years ago, I reported on severe problems with bunching on 70 O’Connor.

At its meeting of December 12, 2019, the TTC Board endorsed a motion by Commissioner/Councillor Bradford whose ward includes the O’Connor bus:

Notice of Motion – Review of 70 O’Connor Bus Route

TTC Board Decision

The TTC Board, at its meeting on December 12, 2019 adopted the following:

That the Board directs staff to investigate and report back by Q1/2020 on the 70 O’Connor bus route reliability, in response to Steve Munro’s published analysis on his website on November 20, 2019.

The pandemic lockdown intervened, and the requested report did not appear. However, schedules on the route were changed to improve running times and a chronic problem of bus bunching ceased to be a problem as charts in this article will show.

In place of bunching O’Conner’s major problem in 2021 is that buses are frequently missing from service. Because of the branched nature of the route with headways ranging from 18 to 30 minutes on each branch, the effect of a missing vehicle can be quite severe. With few buses on the route, adjusting service by changing the spacing of remaining vehicles is not an option. In many cases, only one bus remains on a branch.

When all of the scheduled vehicles are in service, headways and travel times are fairly consistent, and buses often have generous layovers (considering the length of a one way trip) at both terminals.
