I'd argue they are always on their own.. But anyhow.. I've heard supervisors being called to Peel and York before, I'd imagine you don't hear much because they rarely go up there. Same deal as Police.
dave042583, nice setup and good info. when i listen to 13 and 14 division, the dispatcher sounds like a different lady. are you sure its the same dispatcher? Also, how are the "Temporary Use" talkgroups assigned? The 71 through 7G talkgroups are very busy, but I can't make sense of what each channel is used for.
13 and 14 aren't patched. Patched groups are: 11/12, 13/61, 22/23, 32/33, 51/53, 54/55. The spare groups are assigned as the need arises.. there's no set order or reason.
