The Canadian Radio-television and Telecommunications Commission approved a separate TSN2 channel in 2000. CRTC Decision 2000-720 granted the initial permission for this new network yet it never launched due to strict prohibitions on live programming.
The channel officially launched on the 29th of August 2008 at 7 p.m. ET. This launch replaced the old alternate feed which had been discontinued in August 2008.
Extensive coverage of auto racing and tennis formed the core of their initial strategy. The channel also began carrying a much larger number of live events during conflicts on the main feed after regulators allowed multiple feeds nationally in Fall 2006.
Rogers Cable did not carry TSN2 from its launch leaving viewers without access to select Toronto Raptors NBA games in the team's home market. TSN2 was finally added to the lineup in May 2009 following months of negotiations.
TSN received official permission to use streamlined conditions of licence on the 1st of February 2010. Broadcasting Decision CRTC 2010-49 formalized these changes as Category C licensing allowing TSN2 to operate independently with no limits on additional programming.
