The only time I've ever reported or contacted them about anything was a few months ago by filling in the
suggestion form (to suggest that they maybe consider boarding up the
Queensway/Parkside stop if it's never going to be repaired, drained, or cleaned).
The
SafeTTC app seems to be only for reporting emergency, dangerous, or immediately unsafe conditions, something roughly equivalent to 911, although now that I read their description it does also mention "harassment" and "suspicious activity" (whatever that means?). I think there maybe there needs to be something that better explains what should and shouldn't be reported. I'm guessing they don't want us wasting their time by reporting things that some may consider to be a problem, but are far too trivial to be considered an emergency.
Something like a crack/meth enthusiast walking around inside a subway car yelling racial/sexual epithets and occasionally throwing objects around is unpleasant and somewhat annoying, but not an emergency and not really 'harassment' either, and somehow I doubt it would be anything TTC security could or would want to do anything about anyway.
