I'm in NW Toronto and hear them very well using a ST-2 Scantenna that's roof mounted and a BCD536HP. I was listening to Animal Control talkgroup just a moment ago. I could even hear ambient noise from within the vehicle that they were sitting in. Most of my monitoring is with headphones, so even if a fly farted, I'd probably hear it.
Sometimes I will notice a Transit talkgroup that will hang on the system so I'll just lock them out.
