Beginning in 2006, the CRTC officially allowed TSN to operate national secondary digital feeds with limited amounts of alternative programming. Following this development, TSN began to use such a feed to broadcast additional programming that could not be aired on TSN due to scheduling conflicts or other events. On August 29, 2008, the feed evolved into a new 24-hour channel, similar to ESPN2, known as TSN2. Upon its launch, TSN2 was legally considered a west coast timeshift feed of TSN, although soon after TSN2 was launched, the CRTC announced a proposal to remove genre exclusivity protections for "mainstream sports" and "national news" channels in the near future. As a byproduct of the decision, TSN would be allowed to use streamlined conditions of licence (legally referred to as a Category C license as of September 2011), which state that the service may offer "multiple feeds" consistent with their licensed programming format, without any restrictions on alternate programming. TSN was officially permitted to use these streamlined conditions of licence on February 1, 2010.
