On June 15, 2022, City Council debated a report about future LRT lines in the Waterfront and on Eglinton Avenue East. As with all transit discussions transit discussions, other topics including the Sheppard West subway made an appearance. A short staff presentation added a few more details about problems at Kennedy Station that triggered changes in the Eglinton East proposal.

The Changing Configuration of the Scarborough Subway Extension and LRT
Some of the issues at Kennedy Station arise from changes made over the years in the Scarborough Subway Extension (SSE) project effecting the alignment and size of the subway tunnel. The staff presentation did not explore all of this history, but one cannot really understand what has happened without all of the details.
The City talks of Metrolinx deciding to widen the subway structure, but the story is more complicated.
The original plan for Kennedy Station (when the Scarborough network was LRT-based under Transit City) would have seen the new LRT station immediately north of and adjacent to the subway station. It would have been a multi-level station given the number of lines it would serve.
- The bottom level, at the same elevation as the subway platform, would have served the Crosstown (Line 5). This would have provision for eastward extension under the GO corridor and then surfacing in Eglinton Avenue as the Scarborough-Malvern LRT line (now known as the Eglinton East LRT, or EELRT).
- The upper level, at the same elevation as the mezzanine of the subway station and one below the surface bus loop, would have served the LRT replacement for the SRT (SLRT). There would have been a large loop and loading platform at the north side of the mezzanine somewhat like the arrangement at Spadina Station for the 510 Spadina streetcar, but considerably larger given the passenger volumes and size of trains that would operate on the SLRT.
This configuration would give a short transfer connection to the subway via the mezzanine up one and then down one level for the Crosstown, or simply across the mezzanine from the SLRT and down one level to the subway. Connections to surface bus routes would not change.
Drawings for this design are in the following article from July 2016:
Here is a cross section showing the platforms for the SLRT and Crosstown stacked west of the GO corridor, and the SMLRT to the east. It was already in its own station and shows a two-car train rather than a three-car train for the Crosstown and SLRT.
When the City proposed the SSE, the extension included a third track east of Kennedy Station that would be used to short turn half of the peak period service similar to what was done at Glencairn Station on the Spadina leg of Line 1 in pre-pandemic service. This scheme also had the advantage that it could be operated with the existing fleet of T-1 trains on Line 2, and for time there were plans to rebuild these trains for life to 2040 to avoid a new car order.
This is an example of the budgetary machinations needed to keep TTC spending within unrealistic City targets.
Scarborough Councillors and activists objected to getting only half of the full service, and the third track was deleted from the plan. This made the tunnel narrower, and that was the version of the project Metrolinx inherited in the provincial takeover of the SSE.
Subsequently, Metrolinx reinstated the third track causing the tunnel to widen again. (Any decision on the future service plan will affect the size of the new train order when the T-1 fleet is replaced later in the 2020s.)
Meanwhile, with the deletion of the SLRT from the plan, Metrolinx changed the elevation of the Crosstown station to be at the mezzanine level as they no longer had to provide for an SLRT interchange. The EELRT, if built as an extension of the Crosstown, would cross under the GO corridor at Mezzanine level and then rise to the surface.
However, the widened subway tunnel does not give enough room for the EELRT tunnel above it, although obviously if this had been designed as a single structure that would not have been an issue. A good example is St. George Station which houses two lines within a single structure. This shows what happens when the province designed its own projects, and the City dropped the ball on necessary integration because the EELRT was much less important politically than the SSE.
As an alternative scheme, a completely separate tunnel would be needed along the north side of Eglinton for the EELRT. This would be built cut-and-cover given how close to the surface it would have to be, and this would mean the acquisition and demolition of many properties along Eglinton.
As I reported in a previous article, the EELRT station at Kennedy will now be on the surface south of Eglinton and East of the GO corridor. It will share access to the subway and the Crosstown line via the existing tunnel to the station mezzanine. No details beyond the drawing below have been provided yet.Continue reading
