Kennedy station

Line 2 Bloor–Danforth was opened on February 25, 1966, and was extended westwards to Warden station on May 10, 1968 and to Kennedy station on November 21, 1980.[6]

An extension of Line 2, called the Scarborough Subway Extension, is under construction that will make Kennedy a through-station. From Kennedy station, the three-stop, 7.8-kilometre (4.8 mi) extension will travel east under Eglinton Avenue, then north under Danforth Road and McCowan Road to terminate at Sheppard Avenue.[7]

Kennedy is being expanded to become the eastern terminus of Line 5 Eglinton. The Line 5 station will be underground, south of Eglinton Avenue East, and about 30 metres (98 ft) north of the Line 2 platforms.[8]

The main entrance to Kennedy station at the southwest corner of West Service Road and Transway Crescent was demolished and has been replaced by a new entrance to access the Line 5 concourse to be located one level above the Line 5 platforms. Two elevators will connect the Line 5 concourse to the Line 5 platform. Two north–south passages will connect the Line 5 concourse to the existing Line 2 concourse. There will be few changes to the Line 2 concourse. A secondary entrance on the east side of the existing GO rail corridor serves as the main entrance to the GO station.[8]

As part of a program to install artworks at major interchange stations along Line 5 Eglinton, Kennedy station will feature two artworks. A mural titled Reorganization of One Hedge by artist Dagmara Genda will consist of photographs of leaves taken from the same hedge, that will be printed on the glass of a skylight.[9] A second artwork titled Locations of Meaning by artist Joseph Kosuth will consist of etched tiles with stainless steel inserts, each spelling the word "meaning" in one of 72 languages.[10]

Line 3 train leaving the station, showing the sharp curve that would complicate replacing it with heavy rail

In 1985, Kennedy station was expanded to serve Line 3 Scarborough, an elevated light metro line with six stations. In 2023, Line 3 was decommissioned and is planned to be replaced by a Line 2 extension to Scarborough City Centre.

Although Line 3 trains had bidirectionally operated metro trains, the tracks for Line 3 extended beyond the top-floor platform into an above-ground turning loop, similar to those found on the Toronto streetcar system. This was because Line 3 had been planned as a dedicated right-of-way streetcar line rather than a metro line. As such, the top-floor platform was designed to operate streetcars. Line 3 was later built as a medium-capacity rail transport line to use the Intermediate Capacity Transit System train models built by Bombardier Transportation. The line began using two-car trains, which were able to travel along the turning loop, but was later converted to use four-car trains, which could not be operated along the tight loop. Thus, the use of the loop for reversals was discontinued after 1988, although the loop's elevated structure remains over the passenger pick-up and drop-off building and was occasionally used as a tail track to store trains. The station platform was reduced to a single track and began using the Spanish solution of unloading and boarding passengers at Kennedy. Original floor finishing and platform edge markings for the planned light rail can also be seen along the current tracks.

Line 3 trains originally looped at the west end of the station, which was double-tracked, but was converted to single track with the platforms on both sides now providing access to the reversing trains.
