Yes and no. For the trunked (TMR) radio system, usually you will only receive the sites that are in your area, unless you have an external antenna up nice and high, and you don't live at the bottom of a hole. And even then I wouldn't expect to receive any of the sites (towers) around the Kentville area as an example. Now because of the way a trunked system works though, if there are any Kentville area users of the TMR travelling through your area, their radios are going to affiliate with the local towers there in Bridgewater, and you'll be hearing their 'home' talkgroup.
Fire in the province is a mixture of regular non-trunked VHF, and some talkgroups on the TMR. Make sure you all those EO-W1 through EO-W4 talkgroups, as they'll be the primary talkgroups for western NS fire departments on the TMR. Also make sure you've got the conventional (non-trunked) VHF frequencies listed in the database for the various fire departments in Lunenburg County, and the surrounding counties for good measure, but again unless you have an antenna up nice and high, don't expect to get much more outside of the county.
