The Aboriginal channel that used to be on both Sirius and XM was moved to Sirius only and combined with the ATN Asian Radio channel when Sirius Canada & XM Canada merged. Essentially, the South Asian audience wasn't big enough to justify its own channel (when the Canadian providers already have a small number of channels allotted). And, the fine print on the Aboriginal channel requirements stated:
"The licensee shall distribute an Aboriginal channel. An “Aboriginal channel” is a channel at least 60% of the programming of which in a week consists of audio programming that is directed toward Aboriginal persons and includes original or previously broadcast programming by, about or including Aboriginal persons. This channel may consist partly or wholly of programming from other broadcasters."
So at this point, from what I can tell, Sirius/XM Canada seems to no longer be claiming any association with AVR, and instead has automated music with a variety of English Canadian and Aboriginal Canadian artists (mostly English Canadian) playing from 3 AM to 6 PM ET daily (62.5% of the broadcast day). However, they are carrying the excellent (IMO) National Aboriginal Music Countdown, which is apparently syndicated to a network of terrestrial stations across Canada, at 10 AM - 12 Noon Saturdays, 4 PM - 6 PM Tuesdays, and 8 AM - 10 AM Thursdays. Presumably as long as the automated music is programmed, selected or otherwise produced by someone who is Aboriginal, it would seem to comply with the letter of the regulation. I would love it if Sirius/XM Canada would pick up a few more music intensive shows; perhaps an Aboriginal Hip Hop mix show or something? Also, if they could offer the NAMC on demand in their web player, I'd like that.
During the remaining hours, 6 PM - 3 AM (37.5% of the broadcast day), they still carry the most popular shows from ATN Asian Radio. A schedule is available at
http://www.atnasianradio.com/ . The schedule seems to show programming on from 3-4 AM, but I believe that the Aboriginal programming begins at 3 AM, however I have not stayed up that late in a while to check. To stay under the allowed 40% of non-Aboriginal content, presumably ATN couldn't have more than 9.6 hours out of 24 hours, so it seems that it should cut off at 3 AM.
