Logged some traffic today on TG 2058 with my SDS200 in discovery trunk mode. It was clear P2 traffic with two techs talking if they could see their RID's Im not sure what 2058 would equate to on the old system.
It would be 32928 which would put it in the Common Interagency range.
Seeing a bunch of encrypted traffic off of Britannia with TG 696. RID's are in the 4021×× range.
Also saw group 1011 key up. Audio but no voice.

BMR was out at Lambton EMS HQ yesterday doing some radio installs. Saw groups 21066 20605 21650 have affiliations from the same radio id. Today group 20601 was active with AES in use.
Radio ID was 750022, 750080
Heard them on FleetNet doing Emergency button testing on some ambulances, then on 4 portables. So good assumption these are EMS groups/id's since it was at the same time they were doing those tests.

I've seen 2051 and 2052 active. Both Phase II and in the clear. Both would convert to Police Common and Fire Common.
I saw 19114 pop up today also and totally encrypted. Not sure what that coverts to.
Ive also been seeing a ton encrypted traffic on 696. Not sure if this is perhaps OPP?

Getting a good signal and tone on 142.380. Quite possibly the Caledonia tower, as that is the ACC for FleetNet.
If anyone else can confirm this, that would be great.

Likely it is as it is identifying as King City primary FleetNet CC site here in Toronto.
In London I have heard EMS using 771.84375 and 773.03125
Also logged 880 today. lots of Encrypted traffic on it

As there are no 142.880 FleetNet assignments to date, I suspect if you were hearing digital traffic on 142.880 in fact that was the South Simcoe PD NXDN system on 142.8825. Perfectly receivable from the Toronto area, but fully encrypted and not P25.
That system does not use the standard 15 kHz channel spacing in that band so the "steps" aren't going to fit into what we're used to calculating. A typical scanner isn't going to display the proper center frequency but it's bandwidth will be wide enough to receive the slightly shifted (2500 Hz) carrier frequency.
Standard 15 kHz steps in Fleetnet use 142.845, 142.860, 142.875, 142.890 etc. so 142.880 is invalid.
Here's what it looks like on the radio spectrum. Note the Fleetnet activity on 142.875 and 142.890 (then 142.905) on either side of it.
Make sense?

I have been running DSD+ on this all evening and along with the 1038Hz P25 tone I have been seeing this in the data stream.

What your seeing is the normal 'Idle' test for the site. Both timeslots are active with the 1038 Hz tone. A radio on the site would hear the tone no matter what slot is entered or assigned.
DSD should also provide a Site ID and some info on the CC.
Judging by the frequencies posted in this thread and if I've followed along correctly, this frequency should round out all the VRs for EMS if it's anything like fleetnet.

My belief is that the available 700 DVRS freq were assigned a sequential individual PL for each frequency. If so then PL tones
69.3, 71.9, 74.4, 77.0, 79.7 and 82.5 may also be OPP related DVRS or 700 simplex frequencies. K9, TRU, VIP, ERU type of use.
PL tones 100.0, 103.5 and 107.2 could be anything or unused?
PL tones 114.8, 118.8 , and 123.0 should be MOH assignments
This is only speculation on my part but it does seem to account for the lack of duplication of PL tones.

Looks like those were added to the database based on your post so you can't really go by them.
Have you confirmed any of those frequencies or was it just an educated guess?
