The Oval X-Treme were founded in 1995 as an amateur team for women's hockey players in Calgary, quickly developing a heated rivalry with their northern counterparts, the Edmonton Chimos. In 2002, the Oval X-Treme were approached, along with the Chimos, to join the National Women's Hockey League (NWHL). The two teams joined the Vancouver Griffins to form the West division of the NWHL. After the 03-04 season, where the Oval X-Treme and Chimos faced only each other due to prohibitive costs to fly out east, the two franchises left the NWHL to form the five team Western Women's Hockey League. In 2006, the two leagues were reunited under the NWHL banner. However, this was short lived as the NWHL and WWHL could not reach an agreement upon a playoff schedule. As a result, the merger was not consummated. With the collapse of the NWHL in the summer of 2007, the Western Women's Hockey League was once again a completely independent league.
The Calgary Oval X-Treme suspended activities for the 2009-10 season.
Partially as a result of the Canada national team being based in Calgary, the Oval X-Treme featured many of Canada's top women's hockey players, including Hayley Wickenheiser, Danielle Goyette and Cassie Campbell. As a result, the Oval X-Treme became the undisputed powerhouse of women's hockey in western Canada, winning five consecutive league championships, and compiling a regular season mark of 95-3-2-1 in their last five seasons.
Gina Kingsbury joined the Oval X-Treme in 2006. She had 31 points (11 goals, 20 assists) in 19 games as the Oval X-Treme went on to win the Esso Women's National Championship.[1] In her second season with the Oval X-Treme, Kingsbury scored 20 goals and added 25 assists in 23 games.
