Both streams are from Toronto, so the schedule is in Eastern time. They invite listeners to contact CBC Audience Relations with any suggestions or comments. I've dropped them a line noting that I appreciate having the Ogg feeds around; if you find them up your alley I'd encourage you to do the same.
On the subject of CBC and Internet radio, you might also like CBC Radio 3, the CBC's flash-based Internet-only stream of Canadian indie music.
Also nice: for those not using their Ogg streams (or if the Ogg streams are not working, which seems to be the case for Radio 2 at this moment), they note on their main streaming page that they test their standard (Windows Media) streams in mplayer to make sure that they're accessible from Unix. Nice.
