While the Canadian iterations of Sirius and XM Radio still maintain separate businesses the competition between them has heated up. The addition of new channels on both radio options seems to be the newest tactic for both companies to try to win over new subscribers.

Single artist channels and entirely new broadcast shows (and genre-centered channels) have been added through both XM and Sirius. The changes will take effect within the next few days so users should check receivers for any differences in their listings.

Unfortunately, Canadian radio regulations necessitate that the new channels replace existing ones so the further additions will only really reschedule the programming.
