But you guys have an unlimited supply of Britanny or whatever flavour of the month is playing on the radio.

Actually, I think we're also exporting all of our Celine Dione discs down South too.
Canada (Southern Ontario) has always been very lucky with UK artists. There's a viable market here for artists that don't crack the Billboard lists in the US, so we get a lot of domestic releases that will never show up on US shelves. Though sometimes it just takes a few days or weeks before some titles are released in the US. I'm pretty sure Pulp's We Love Life was released Stateside, no?
