On November 24, 2000 Global Television Network Inc., a subsidiary of Canwest, was granted approval by the Canadian Radio-television and Telecommunications Commission (CRTC) to launch a national English-language Category 2 specialty television service called Extreme Sports, described as "featuring the best of "off-beat" sports programming that will give Canadians the opportunity to live vicariously through the ultimate high associated with such extreme pastimes as high altitude sky diving, cliff diving, white water rafting, and mountain climbing.

[2] Amid the mid-2000s financial crisis and a mounting debt load, Canwest announced in September 2008 that it would be shuttering X-Treme Sports, with an expected closing date of October 9, 2008.

Through its official statement, Canwest cited low growth potential as the reason for its closing of the service, noting funds would be better directed to other channels with greater growth potential.

In December 2010, Leonard Asper, the former CEO of Canwest by that point after the assets were sold to Postmedia and Shaw, acquired Fight Network through his Syngus Corp. holding company via its Anthem Media Group marking the return of sports television ownership.

Series primarily focused on the sports within the firm definition of extreme sports, such as motocross, mountain biking, surfing, skateboarding, and snowboarding; however, other forms of extreme, adventure and thrill-seeking sports/activities included MMA, professional wrestling, and slamball.
