For fire, look in the link from mciupa.
The department conducts it's operations with dispatch in lindsay through the 4 frequenicies labelled "xyz repeater" (Pontypool, Lindsay Kirkfield and Kinmount respectively).
Fire pagers operate on the frequency labelled "Paging." The other fire frequencies are talkaround frequencies for on scene chatter - you will need to be close to the scene to hear anything on this as they are not run through a repeater. Don't recall which one Omemee uses.
As well, MikeOxlong's thread "http://forums.radioreference.com/eastern-canada-radio-discussion-forum/17856-programming-your-uniden-scanner-bell-mobility-radios-fleetnet-system.html" details programming the Fleetnet system into your scanner, which will cover pretty much all Ontario gov't agencies (OPP, EMS, MNR, etc.).
