Have a play around on the ACA site - www.aca.gov.au  spec:

The 40 public UHF channels in Australia sit around 477 MHz, everything 
above and below this in the range you mentioned is covered either by 500 
and 800 MHz upper and lower band spectrum licenses, as well as as a ton of 
'Broadcast Services' and 'Land Mobile > 30MHz' licenses.  Included in this 
is a lot of community TV stations and outback shire councils.  To give you 
some idea of how many licenses sit in this space, the maximum range you can 
search for is 1 Mhz, or it returns too many results and refuses to display 
them.  In some cases 0.1 MHz is the most you can search on.

I'm guessing in America/Canada there would be even more licenses in that space.
