The following frequencies are for your area:
Canning - 165.660
Kentville - 153.860
New Minas - 153.920
Wolfville - 154.430
Windsor - 151.460
Waterville - 159.525
All of the previous stuff from my first reply is province-wide and could be heard in any part of the province at any time. However, as I said your scanner will not be able to monitor those. Hope this helps.
Are you picking up a new scanner? If so, there's things you need to know.
First, you can find used scanners on ebay capable of trunking for as cheap as $70-100. However, there's a problem with those. Currently the provincial trunked system uses frequencies in the 800 MHz range. There's rumor the system is going to move to frequencies located in the 700 MHz range, and the majority of those used scanners on ebay cannot scan 700 MHz. Although the province hasn't made any announcement on when they're moving the system to 700, we know they've begun doing some testing, so a move could in theory happen anytime. Could be 6 months, could be a couple of years - or it could even be never. So if you want a scanner which is future proofed, you're going to pretty much have to buy a brand new on, and you're going to more than likely pay around $200. I would throw my support behind the GRE PSR-300 scanner, which supports 700 so you're good for any future changes.
Second, while the RCMP do use the provincial system, they are on digital channels, and to monitor the digital channels (and the RCMP) you need a digital scanner - so instead of paying $200 for a non-digital scanner, you would need to pay around $500 for a digital scanner. Not a cheap hobby, and I just want to make sure you're prepared.
So can you get away with a cheap $70 scanner on ebay? Sure. Try for a RadioShack Pro-95, or sometimes you can find a Pro-97 for cheap too. They're both good radios. But keep in mind if you go that route, if the province migrates their system to 700 MHz, you will no longer be able to monitor the system and will have to buy another new scanner.
Can you get away without buying a $500 digital scanner? Of course. In the Kings area, the only users who are on digital are the RCMP, so if you don't need to monitor the RCMP don't buy a digital scanner. Kentville I believe has its own police, but they don't use a digital system so you would be able to monitor them just fine without a digital radio. Some Department of Natural Resources (DNR) users are digital, specifically the enforcement people, but they rarely seem to talk about anything too interesting - all of the fire-related DNR communications are on non-digital channels, and that sounds like what you're more interested in listening to.
You also may want to read over some material on just what trunking is, because you'll need to have a rudimentary understanding to be able to program your scanner and figure out just how the system works from a listening perspective.

I hope this is helpful to you, let me know if you need clarification or further advice.
