I'd highly recommend CBC Radio's Spark podcast and CBC Radio 3 Sessions podcast.
As far as music, some albums I'd recommend:
Amy Millan: Masters Of The Burial
Bat For Lashes: Two Suns
Charlotte Hatherley: The Deep Blue
Charlotte Hatherley: New Worlds
Elliott Brood: Mountain Meadows
Howling Bells: Radio Wars
Jane Vain and The Dark Matter: Love Is Where the Smoke Is
Jets Overhead: No Nations
Joel Plaskett: Three,
Truthfully Truthfully, Ashtray Rock <- A fantastic album
Lou Barlow: Goodnight Unknown
Metric: Fantasies
Sarah Blasko: As Day Follows Night
Stars: Sad Robots
, Set Yourself on Fire, In Our Bedroom After The War
Wintermitts: Heirloom
...ah yes, you can easily predict what else is on my iPod

/admits to avoiding RIAA labels as much as possible, as far as I know Bat For Lashes & Sarah Blasko are the only two on RIAA labels(if you're on a total boycott of the RIAA).
