Your FT-250 looks like a decent amateur 2 metre handheld radio but
not good for trunked systems like Fleetnet. You can scan the frequencies
of any site (except the control channel, but include the alternate CC).
MOH ambulance and MTO road ops are analog which you will hear, but
due to dynamic assignment of frequencies, messages will be fragmented.
Also, OPP and some MNR/MTO ops are digital, which you will hear as
annoying noise; nothing you can do.
The 1s carrier you hear is on all voice channels and the alternate CC,
once per minute.
Another minor issue is that more analog users are narrowband FM
analog, which means you will hear them, but I don't think your radio
has that option, so the volume will be lower. Analog users on Fleetnet
If you're sufficiently interested and have the money, consider a scanner.
Even a good used analog scanner will give you some Fleetnet listening.
Even a new scanner like the Uniden BC346XT runs $240 +taxes/shipping,
which does analog trunking. Anything digital typically runs at least twice
the cost. Durham Radio and Radioworld are sources.
I don't see much in the database here for your locality, just a bit under
Thunder Bay. I suggest searching the Industry Canada database for
frequencies, plugging them in, and seeing what's on them. Be aware
that IC blocks "sensitive" police, military, and some gov't frequencies.
By searching frequency ranges you can discover frequencies noboby
has identified, which in itself can be rewarding, as well as helping the
hobby; something that happens not nearly enough, and unfortunately
is on the decline as people get used to downloading frequencies that
are collected by a small number of people.
I can provide details on searching the IC TAFL database. It's not all that
difficult, once you get used to it, and provides a wealth of info. You can start
with a Licensee Name Search keyed on "Geraldton":
For rail operations try searching the range 160.10 to 161.60 (approx.).
You can search IC database frequency range based on your location
and search radius.
