Saw this little gem while driving around, decided to stop and check it out. To the west is a retirement home which the railway runs right beside, to the east is the 401. I did some snooping around online to see if I could find who this railways belongs to so I could get a name and it looks like this used to belong to CPRS. The railway used to go past where you will find the end of it today, and would go to Lens Mill. However, the 401 had changed that and the railway was active up until around 2009. Then the city had the railway paved over and it's been neglected ever since. You can still find the railway tracks there and some other assorted railway items such as power boxes and some telegraph poles. Most of it is overgrown and a pain to walk through, however the section near the 401 is fairly clear and provides some nice photos. Most maps will still show this as an active railway, but once you get there, its obvious that it isn't.
Will try and get more photos to add
