Scarborough Centre station was opened in 1985 along with the rest of Line 3. The station replaced transit access to the
Scarborough Town Centre shopping mall's south side (at ground level along roadway). In 2000, this station became accessible with elevators. The
Toronto Transit Commission had planned to extend
Line 4 Sheppard southeast from its current terminus at to Scarborough Centre. The 904 Sheppard–Kennedy Express bus currently links the two stations, making limited stops along
Sheppard Avenue. In March 2007, however, the TTC dropped this plan when it announced its
Transit City proposal to build the
Sheppard East LRT. The LRT proposal was later replaced by a plan to extend Line 4 eastwards from Don Mills station to McCowan Road. In 2013, the proposal was changed to abandon the Line 3 right-of-way and build an underground extension of
Line 2 Bloor–Danforth along McCowan Road. This would result in the decommissioning of all Line 3 stations beyond Kennedy station. A new Scarborough Centre station would be built east of the current station and would be oriented on a north–south alignment rather than the east–west alignment of the current station. Between 2013 and 2016, the new Scarborough Centre station was planned as a through-station. In order to save money for another transit project, the plan was revised in 2016 to make it a terminal station. However, in 2019 the plan was revised again to make the new Scarborough Centre station a through-station. However, the rail portion of this station permanently closed following a derailment on July 24, 2023, after which the TTC decided not to reopen Line 3. ==Station description==
