In all my years of listening to scanners I've never heard any chatter from either of these Police Services on their channels. Has anyone heard them?
Most likely CN. CP is using Wave On Cloud for their ops with AES-256.Very little. One of them (I forget which) was on the ClearNET (then MiKE) network for a long time. They will be NXDN capable now too.
Same with Military Police around my area.... never heard a thing.
