What you want to listen to an how much money you have to spend
will narrow down the scanner you will want to get.
There are many older/used and cheap scanners that will allow you to
listen to rail, marine, aircraft etc. for as little as $50-$100. This may prove
limiting as newer shared systems pool frequencies, so no particular user
is on a "frequency"; for that you need a trunking-capable (trunk-tracking)
scanner which once programmed properly (can be a chore initially), will
sort that all out.
I have old non-trunktracking scanners in addition to trunktrackers (but
no digital) and they have all found a use for various services. Ottawa Police
have been digital since 1997, though not decodable by any scanner; and
I've grown away from listening to police per se so don't miss the OPP all
that much. Most people seem to want OPP, and in your area you could
also listen to Hydro Quebec, but that's about it for digital in your area
(other than new formats that can't be received).
At very least, to listen to MOH (ambulance) and MTO road operations
you'll need an analog trunk-tracker such as BC346XT which can handle
Motorola VHF trunking (some older trunking scanners can't, or don't do
it very well). If you want OPP and some MTO and MNR operations,
those which do not use encryption on top of digital (it's important to make
the distinction) you'll need a digital (P25) scanner, which ups the price to at least
$400 new if not higher.
As for 800MHz, you are sufficiently far from Ottawa or other major
centre that uses 800MHz trunking, so unless you travel to such places,
having 800MHz capability is irrelevent; but most modern scanners have
800MHz capability anyway. Last time I was in Pembroke there was a
tiny bit of listenable 800MHz activity (some LTR trunking), which you
almost don't need a trunking scanner to cover. The bulk of 800MHz
commercial activity is iDEN digital format (Telus MiKe) which again
scanners can't pick up and very little chance they will be able to in future
for a number of reasons (topic for later discussion).
