Esso Women's Nationals

The Esso Women's Nationals was the Canadian women's senior ice hockey championship from 1982 to 2008. The winners of the event received the Abby Hoffman Cup. The second place team was awarded the Fran Rider Cup, while the third place was given the Maureen McTeer Trophy. Nine or ten teams (depending on the tournament) qualified for the event, with two from the province hosting the event. The event was sponsored by Esso.

Since the split between the National Women's Hockey League and the Western Women's Hockey League in 2004, this was the only event in the professional women's hockey calendar that saw teams from the two leagues play against each other. Although an agreement between the NWHL and the WWHL was reached in 2006 to merge the two leagues (wherein the latter would be absorbed as a separate division of the former), difficulty in setting up the Nationals alongside an interlocking playoff format prevented the merger from taking place - the Nationals eventually would take place mere days after the WWHL playoffs and before the NWHL playoffs.

With the collapse of the NWHL soon after and the establishment of the Canadian Women's Hockey League in Eastern Canada, the Esso Nationals, which will also serve as a playoff of sorts between the WWHL and CWHL, received a format overhaul in 2008, in which the top two teams from the WWHL (representing British Columbia, Alberta, and Saskatchewan) and the top two teams from the CWHL (representing Ontario and Quebec) automatically qualified for the event. Teams representing the provinces without teams in either league filled out the remainder of the field, due to Hockey Canada requirements that every province be represented. The Abby Hoffman Cup was awarded to both the club pool and the team pool champions. Similarly, the Fran Rider Cup and the Maureen McTeer Trophy (the trophies awarded for the silver and bronze medalists at the Esso Nationals) were awarded in both the club and team pool tournaments.
