After Sirus, XM and CHUM were granted licenses by the CRTC to launch satellite radio services in Canada, there's been little news. XM Canada said earlier this week it had pre-signed 3K customers at a couple events, and today unveiled a retail deal with Best Buy and Future Shop. XM Canada, which is majority owned by John Bitove's Canadian Satellite Radio, plans to invest $100-million to offer the service across Canada. Niether XM or Sirius have announced when their services will be launched or pricing, while it's doubtful CHUM will get into the business.
