The TSN licence currently comprises five 24-hour programming services; from its launch until 2006, TSN operated as a single, national service. In 2006, the Canadian Radio-television and Telecommunications Commission (CRTC) ruled that TSN could operate multiple feeds with a limited amount of alternative national programming—this was followed by the launch of TSN2—a second 24-hour network under the TSN licence that was legally considered a west coast feed of TSN. As of 2010, TSN has been subject to deregulated Category C licensing by the CRTC, which allows multiple feeds to be operated under the TSN licence with no restrictions on alternate programming; TSN used this new ability to operate an autonomous TSN2, along with part-time feeds for regional NHL coverage.
