The proposed SmartTrack Go train station for Finch/Kennedy in Scarborough, called the Finch East station, will be the station right between the existing Milliken (near Steeles Aveenue) and Agincourt (near Sheppard Avenue). Finch is a very busy route and the station would connect people to the more east-bound Finch express buses.
There are, as always, concern over implications for building in this location. The current location includes a medical building, a small shopping plaza, a small Chinese grocery store, Purolator center and a storage space business.

The two plans do differ slightly. Steve Munro’s map shows development on the east side of the ttracks, where Purolator and Public Storage would need to be expropriated, thus saving the Chinese mall and small supermarket on the west side. A significant 40% of the land on the east side is already green space.
There would be a 220 space parking lot, passenger pickup area and a 10 bus bay terminal. A grade separation would also need to be done, which might be a dip in the road, with the Go train overhead.
The conclusion of the Finch East Metrolinx assessment document is a bit surprising:
The initial business case analysis for the potential Finch East station shows a development at this location would be in line with overarching provincial and municipal goals with respect to policy and strategic vision. In addition, this station would be in a good location with respect to track geometry and overall station constructability. However, both the financial and economic analyses indicate that the station plan, as it stands, has a negative financial value for Metrolinx and would reduce economic wellbeing for society as a whole…
From Table 8-1
There is potential to relieve parking constraints at Agincourt station. Station is not close to other potential new stations. The potential Finch East station
would connect to Finch Avenue transit routes which are the busiest routes outside
of downtown Toronto, providing excellent connectivity to local transit. No duplication of other existing or committed rapid transit.
So what does this really mean? This proposed station would be strategically acceptable for Ontario, but would cost more money to build and run? How can this station “reduce economic wellbeing for society as a whole” if it saves a lot of time and effort for citizens? Do they take that into account?
If cost is an issue, then scale back the 10 bus bay terminal as well as the 220 car parking area. This should significantly reduce the cost of the project. Why do you need a 10 bus bay when there are only 2 bus lines, the 199 Finch Express, and the 39 Finch East, running on Finch. It is also not a terminal stop.
