July 21, 1991

Coincident with a re-organization of bus services along Eglinton Avenue, service begins on a new 124 SUNNYBROOK bus, replacing portion of the 28 DAVISVILLE and 11 BAYVIEW routes, and restoring a route name that had not been used since 1954. Buses operate between Lawrence station and Sunnybrook Hospital via Lawrence and Bayview. During rush hours, every third bus operates via Mildenhall and St. Leonards, westbound in the morning and eastbound in the afternoon. This is not listed as a separate branch, initially, but by 2002, this service was referred to as 124A. The route is operated from Eglinton Garage.

February 18, 1996

As a result of systemwide reduction in service resulting from an elimination of provincial subsidy, late evening Sunday service is removed. Also on this date, operation of this route is transferred from Eglinton Garage to Wilson Garage.

January 7, 2002

Service further reduced, to 20 minute frequencies on Monday to Friday evenings and all day Saturdays.

May 11, 2003

Running times lengthened during the afternoon rush hour, to improve service reliability. Frequencies decreased as a result to every 10 minutes.

August 31, 2003

Service increased to reduce crowding, with an additional trip at the end of the morning rush hour, and frequencies improved in the afternoon rush hour to 7 minutes, 30 seconds.

July 31, 2005

Service made accessible using Orion VII low floor buses. The change in equipment is co-incident with the move from Wilson Garage to the new Eglinton Garage, on Comstock.

February 19, 2007

Rush hour service on Mildenhall eliminated (last day of service was Friday, February 16, 2007). All buses now operate over the normal route between Lawrence station and Sunnybrook Hospital.

November 23, 2008

As part of service improvements related to the Ridership Growth Strategy, Sunday and holiday late evening service is reinstated. Also, morning rush hour service is increased to every 6 minutes, 30 seconds. Also on this date, the route is transferred from Eglinton Garage to Wilson Garage, and buses utilized on the route are bike racked equipped.

May 8, 2011

As part of a series of system-wide service reductions resulting from municipal budget cuts, service after 10 p.m. on Sundays and holidays eliminated.

September 6, 2015

Late evening Sunday and holiday service restored. Buses now operate at intervals of 30 minutes or better whenever the subway is open.

October 11, 2015

Night service is installed with the extension of 352 LAWRENCE WEST NIGHT bus to Sunnybrook.

June 23, 2019

Plans for this board period would have altered this route. Due to renovations at Lawrence station shutting down one of the bus platforms at the station, buses on the 124 SUNNYBROOK route would no longer enter the station itself, transferring its passengers to the subway at on-street stops. To turn around buses, the service would extended via west on Lawrence and north on Avenue Road to Old Orchard Grove, before turning through Roe Loop and returning via the reverse loop. However, at the start of this board period, the bus terminal at Lawrence station remained fully open, and the diversion did not launch.

February 25, 2020

On or before this day, with the completion of construction at Lawrence station’s bus terminal, service on 124 SUNNYBROOK returns to normal, with buses returning to platform 4, and no longer looping at Roe Loop on Avenue Road.

November 20, 2023

As it was during June 2019, service on the 124 SUNNYBROOK is extended once more to Roe Loop due to the closure of Lawrence station for 10 months due to massive accessibility upgrades.

Sunday, March 31, 2024

Due to construction at Lawrence West station closing the bus terminal there, service on this route is temporarily replaced by an extension of the 52G LAWRENCE WEST bus operating from Sunnybrook Hospital via Bayview, Lawrence and the Westway to Martin Grove.

The routes were extended west on Lawrence and north on Avenue Road to loop through Roe Loop instead. The photographer is anonymous.

On this day, the YONGE SUBWAY was shut down from Lawrence to Bloor for track repairs, and the TTC was extending 124 SUNNYBROOK buses to Lawrence West station (operating westbound as 52G LAWRENCE WEST) in order free-up the bus bays at Lawrence station to handle the YONGE SHUTTLE buses. Articulated buses were called in to help deal with the situation. The photographer is anonymous.
