The Planning web page on the TTC site contained, until recently, some rather elderly files and reports. Updates were confined to the Scheduled Service Summaries posted about every six weeks.
This page has now been revised. All of the old files/links have been removed, and there is now current (2019-2021) ridership data at a route level.
For the convenience of readers looking for the old files, I have created a new page in the Reference section of this site (see the drop down menu at the top of the page). That section already contains a page for Scheduled Service Summaries going back many years.
