Okay poster, I think you need to go to the Canadian radio discussion forum. This is the system your county is on. Your county alone has 12 sites and their locations. Each site has its own set of frequencies and control channels.
Without more information about where you are in your county we just can't help you here. That's why we ask for your hometown not just your county. I also don't know the geography of Canada and everything is heavily abbreviated.
They will be able to help you in the Canadian discussion forum. Good luck.
PS.. make sure to give them your exact location in the county so they don't have to ask, that's the first thing they're going to want to know. Make sure to give your fire departments name also as talk groups are divided in regions, North east west south.
