First, it would be better if you posted this in the Canadian section of the forum. You'll have a better chance of finding someone who knows something about your area.
Second, you really need to list they type of scanner you have and what you want to listen to. What do you mean by cop shop? Are saying you want to only listen to the police in your area? If so, are they the local police, county police or the OPP?
Third, if you're only going to post one sentence, check it over for spelling and to make sure it makes sense. Yours is a little hard to understand.
