The pro96 will for sure track the old Motorola system. I think it'll track the new p25 one too. Police are encrypted so you're SOL with that. Fire can be monitored, if you want to listen to EMS you can tune into the PPSTN system.
1) Pay for a subscription here
2) Get the free scan program called Free scan or the one I like and that's proscan but it's not free.
3) hopefully you have a programming cord and your scanner can communicate with the software.
4) Log into RR and download Saskatoon, then PPSTN for Saskatoon and area.
