The WWHL had five teams, in Alberta, British Columbia, Saskatchewan and Minnesota, for its own 2004–05 and 2005–06 seasons. The WWHL agreed to merge with the NWHL for the 2006–07 NWHL season. The NWHL reverted to three divisions: Eastern Division with Quebec-based teams, the Central Division with Ontario-based teams, and a renewed Western Division with teams Alberta, British Columbia, Saskatchwean and Minnesota. The Eastern and Central Division teams scheduled a 35-game unbalanced but interlocking schedule, while the Western Division would only play within itself for the regular season - saving travel costs for all three divisions. The merger broke down midseason, with the WWHL teams treating it as the 2006–07 WWHL season and the remaining NWHL teams handling their playoffs with all four teams from the Central Division and the top two teams from the Eastern Division qualifying for the postseason. In the NWHL playoffs, teams played a best-of-three series to determine the Eastern and Central Division champions, who then met for the NWHL championship. By the end of the 2006–07 NWHL season, the league had fallen into disarray, season records are incomplete, and the league folded shortly after the Central Division's Brampton Thunder defeated the Eastern Division's Montreal Axion to win the last ever NWHL Championship.
