Coincident with the opening of the SPADINA SUBWAY, service begins on a new route connecting York University with Wilson station. Buses run from Wilson station (Upper Bus Terminal) via west on Wilson, north on Keele, west on Grandravine, north on Sentinel, and loop clockwise around the university campus via Fraser Drive including a stop at the Ross Humanities Building at the centre of campus. The name of the ring road around the university has been changed from Fraser, and is now known as The Pond Road on the south and west side, and known as Ian MacDonald Blvd on the north and east side of campus. The route operates out of Wilson Garage.

February 25, 1980

Service begins on a new express branch between Wilson station and the Ross Humanities Building at York University. There are no intermediate stops. Buses operate northbound from Wilson station via north on Wilson Heights, west on Sheppard, north on Chesswood, west on Finch, north on Keele and west on St. Lawrence (now known as York Blvd.) to the Ross Building. Southbound buses operate via east on St. Lawrence, south on Keele, east south and east on St. Regis, south on Tuscan, east on Sheppard and south on Wilson Heights. Since there are no intermediate stops, some drivers do not follow the above routing exactly. This service does not operate during the summer (mid-April to the Friday following Labour Day) or during the Christmas school recess. At an unknown year service resumed after the summer break on the Tuesday immediately after Labour Day.

December 7, 1981

Express buses are rerouted both ways between Sheppard and Wilson station via Allen Road and Transit Road.

September 6, 1983

Express service is revised to provide local service between Finch and Keele and York University. From 7 AM until noon (note earlier start time), buses run “local” from the Ross Building south and west on Fraser, south on Sentinel and east on Finch to Keele, then “express” east on Finch, south on Allen Road and south on Transit Road to Wilson station. Buses return northbound north on Transit Road, north on Allen Road, west on Finch, north on Keele and west on St. Lawrence. From 12 noon to 5.30 PM buses run express on the southbound trip and local / express on the northbound trip, using the reverse of the above described routings. It is not clear if the routing via Finch and Allen Road, and the additional earlier and later trips also started at this time it could have started early. Express service will now operates through the Christmas recess at the university.

January 1, 1984

Service on the main branch is rerouted from Wilson station to operate around the north side of the Downsview Airport rather than via Wilson. Trips now begin at the new North Terminal of Wilson station and operate north on Transit Road, north on Allen Road, west on Sheppard and north on Sentinel to the university. Buses on the new 119 GRANDRAVINE and 120 CALVINGTON routes provide service on some of the streets no longer served by 106 YORK UNIVERSITY buses. No changes to destination signs.

Summer 1991

This is the first summer that the express service operates.

January 3, 1993

Upon closing of the Davenport garage, operation of the route is now split between Arrow Road and Wilson garages. The split as of this date is likely, local service at Arrow Road and express at Wilson, based on the February 1994 entry.

February 13, 1994

Operation of all runs on this route are consolidated at Arrow Road Garage, as the Express runs are transferred out of Wilson Garage. This allows express runs to be operated by high capacity articulated buses.

February 18, 1996

Due to the elimination of the 118 FINCH VIA ALLEN route a new stop is added both ways at Finch and Dufferin.

March 31, 1996

With the opening of the new Downsview Station (at Allen Road and Sheppard) on the Spadina line, all buses run into the new Station instead of proceeding south on Allen to Wilson station. Early morning trips (before 6 a.m. Monday through Saturday and before 9 a.m. on Sunday) are extended to Wilson and Transit via Allen Road and Transit Road. At some point before February 2001, these extended trips are designated as route 106A.

Effective on this date, the express branch is redesignated from 106A to 106E.

July 28, 1996

New Orion V lift equipped buses are introduced for the benefit of passengers who use mobility devices. Due to delivery and technical problems the buses were in and out of service through August and September. Also on this day, delays on the Express branch in making the south to east turn at Allen and Sheppard, buses are rerouted via Wilson Heights between Sheppard and Overbrook. It is not known how long this alternate routing was used before buses resumed operation via Allen Road and Sheppard.

February 1, 1999

This is the last day that articulated buses are scheduled for use on this Express service. The fleet of Orion-Ikarus buses were decreasing and all remaining vehicles of this type are transferred from Arrow Road Garage to Malvern Garage.

February 21, 1999

106E Express runs is transferred to Wilson Garage. The local 106 “Sentinel” branch continues to operate out of Arrow Road Garage.

September 3, 1999

Last day of operation of the 106E Express branch. This service is replaced by the new 196 YORK UNIVESITY EXPRESS.

March 31, 2002

As the Orion V lift buses were leaving Arrow Road Garage for the new Eglinton Garage on Comstock Road, this route operated with the Nova RTS lift buses coming from the closed Danforth Garage.

September 3, 2006

Accessible service is improved using Orion VII Low Floor buses, replacing the Lift Equipped Nova RTS buses.

August 31, 2008

Buses on this route are now equipped with bike racks.

November 23, 2008

Coincident with the opening of the new Mount Dennis Garage, operation of this route is transferred from Arrow Road Garage to Wilson Garage.

September 4, 2016

Operation of this route is transferred from Wilson Garage to Arrow Road Garage.
