The league released the following statement on March 13, 2020:
- "The Greater Metro Jr. A Hockey League has been forced to postpone the Russell Cup Playoffs for two weeks.
- Late in the evening of March 12th, 2020, the GMHL was notified by our underwriting insurance provider that a mandatory two week shutdown must be implemented. Our insurance & sanctioning body is the same sanctioning body which governs all of junior hockey in Canada, and we are required to follow the direction of the sanctioning body." 
Following the two weeks, a final decision regarding the playoffs will be provided.
- The league would announce an affiliation with the Western Provinces Hockey Association which had played the 2018-19 season as a division within the Western States Hockey League. By the time that the schedule is released the Hinton Wildcats would not be included, The Enoch Tomahawks would be renamed the Northern Alberta Tomahawks, and the Cold Lake Wings would become the Edmonton Academy Wings despite the fact that the team announced on September 25, 2019 that they were suspending operations for the season. The team is apparently playing road games until the league can find a new arena for them to host games in. The Rosetown Jr. Red Wings don't list any games on their schedule or a roster but are still listed on the league website as a member. The team would later attempt to move to High Prairie, Alberta. The former Rosetown franchise would end up folding and the Edmonton Academy Wings would end up moving to High Prairie November 8th and assuming the High Prairie Red Wings name.
