Hi. The OPP operate on the almost province wide Fleetnet radio system,
You will need a digital scanner to hear 'action.' What kind of scanner do y ou have? http://www.radioreference.com/apps/db/?sid=861
scroll down to OPP Southwestern Region Talkgroups & you will find your areas talkgroups.
Unfortunately, your scanner will not receive the Provincial Police as it is not a digital model. You might have luck listening to their mobile repeaters on 410.8625, but you need to be reasonably close to a cruiser for that to work.
