I am from the UK, but it looks like both our countries have a very similar community radio sector. If you volunteer with one of these stations, it is far more likely you will end up doing a "bit of everything" (including producing content as well as admin work or tech support)
These positions are (at least in UK) normally unpaid volunteer work, but you are of course entitled to the digital recording of your show and can use that as a showreel for applying to other jobs in the industry..
As Canada is big and I don't know where you are exactly, here is a list of every community radio station there..
Is this a problem to that anybody has experienced? I do like to work in a station where there is constant work.
its not something I've personally experienced (my last paid work in broadcasting was 20 years ago in the tech/engineering side, my current day job is in IT/telecoms for healthcare), but it is a known problem here in England especially for younger people (<50 years old), female broadcasters, those of minority groups etc, especially on commercial media and has been for a good few decades. on the rare occasions I listen to UK mainstream radio it is mostly the same presenters from 20 years ago and the companies simply aren't hiring (or if they do the pay is less than working in an office or callcentre)
One problem is that a lot of commercial stations consider the ads to be the most important content and don't even care about anything else!
This is precisely why many people no longer listen to "normal" terrestrial radio and prefer podcasts or online content or even pirate broadcasting (its still a whole subculture in the Netherlands and many of those involved are often our parents age group )
