I'm not sure if there's another station quite like this one anywhere in Canada. It's called CFVZ-FM, a low powered outlet located in Moose Jaw, Saskatchewan. 

What's different about this tiny place is that it appears it's only on the air when what its licenced to broadcast is happening. I'm assuming from what I see of the CRTC rules, it's otherwise mostly silent. According to the Commission, the station, owned by Moose Jaw Tier 1 Hockey Inc., is bound by the following rules:

• The licensee shall use the station solely for the purpose of broadcasting the hockey games of the Moose Jaw Warriors and the baseball games of the Moose Jaw Millers, fastball games from Memorial Field, and selected Moose Jaw High School athletic events. This would include all pre and post game shows, and a one-hour noon-time program broadcast Monday to Friday related to the promotion of events and games of the hockey club
• The licensee shall not broadcast musical selections, except as incidental background music.

I wonder how many remember a similar station near Toronto called CHEV. I believe it was on the so-called X-band at 1610 AM, and was only on the air when it broadcast junior hockey games and the odd amateur baseball match. It was a very odd "get" for DX-ers, since it was never there otherwise. 

It was finally forced to give up its frequency when the CRTC licenced CHHA, the Spanish language station that currently occupies the 1610 slot. 

As for CFVZ-FM - are there others like them anywhere in Canada? If so, I'd be curious to know where they're located and what (and when) they're allowed to broadcast.
