In 2019, the league added the Western Provinces Hockey Association (WPHA) as a Western Division in the GMHL for the 2019–20 season, which then rebranded as the GMHL West. The WPHA had played the previous season in the Western States Hockey League as the Provinces Division. The 2020 playoffs were then curtailed by the onset of the COVID-19 pandemic and no champion was named. The following 2020–21 season did not take place as scheduled due to pandemic restrictions in Ontario and Quebec, with six teams playing only two games each in December 2020. The four teams in the GMHL West were able to play a partial season and a playoff in May 2021. In 2023, all teams from the GMHL West were removed by the league, which then formed their own league called the National Junior Hockey League (NJHL).
