[1] Licensed by the Canadian Radio-television and Telecommunications Commission (CRTC) in March 2010 under the name Rogers' Mainstream Sports Specialty Service,[2] it was launched at 12:00 p.m.

The service was renamed as simply Sportsnet One on October 3, 2011, as part of the rebranding of Rogers Media's Sportsnet-branded channels.

Sportsnet One has acted as a linear specialty television partner for selected CBC Sports programming, including the Calgary Stampede[5][6][7] and the Paralympics since 2014.

[8][9][10] The Sportsnet One license is also used for a series of part-time multiplex channels which carry regional National Hockey League coverage, for selected Vancouver Canucks, Edmonton Oilers and Calgary Flames games.

Some fans canceled Blue Jays ticket purchases in protest,[17] but Paul Beeston, the team president, stated he was very happy to be going with Sportsnet One.
