The TTC now has a Transit Planning page linked from “About The TTC” on its website.
The detailed service summary for the current schedule period is available on this page and, therefore, I will no longer have to host it here.
Missing from the new TTC site are many of the historical reports — operating statistics, Annual Reports, etc., going back to past years. With a bit of sleuthing, you can find some of these on the City of Toronto website by using its search engine to access cached copies of the reports and pages.
A cached copy of the old “Documents” page is still available.
