Updated October 20, 2021: A table has been added as a postscript showing the numbers underlying the charts in the article that consolidate GO and Ontario Line traffic.

Back in May 2021, I wrote about the total number of trains that Metrolinx plans to operate in the corridor between East Harbour and Gerrard Stations. See A Very Busy Go Corridor.

Metrolinx has released a Noise & Vibration Study showing, among other things, a revised table of service levels for the routes that will operate in this corridor. See LSE-JC N&V Operations Report issued as Appendix C to the Ontario Line Lakeshore East Joint Corridor Early Works Report. The detailed breakdown of services by motive power type, express and local, and track assignments begins on page 60 of the Operations Report.

The new numbers differ from those published previously:

• There is an increase primarily in the number of GO express trains.
• The new report includes Ontario Line maximum service levels for 2060 and beyond.

During a recent online consultation for the East Segment of the Ontario Line, Metrolinx claimed that the count of trains cited by the community is too high (at about 1,500 per day) and that the number is around 900.

Quite bluntly, Metrolinx staff should read their own reports. Too often they give misinformed answers to communities to blunt criticism while being out of touch with their own proposals. Whether this is deliberate misrepresentation or simple incompetence is a debate for another day.

The tables in the Operations Report show very clearly the projected counts of GO, Ontario Line and other trains. (Note that there is no provision for the addition of a proposed High Frequency Rail service on top of this.) The numbers in the spreadsheet below are copied from the Operations Report. The only change is the addition of totals.

The grand total of trains on the expanded GO corridor will be 691 of which 581 will operate between 7am and 11pm, and 110 will operate between 11pm and 7am. (See LSE OnCorr Tracks, East Harbour to Danforth – Combined Table, p62.)

The number of Ontario Line trains begins at 912 per day in 2030 (per the Preliminary Design Business Case), ramps up to 984 by 2040 (again from the PDBC) and to 1130 by 2060 (Operations Report).
