The league's vision is to become a sustainable option for senior hockey in the region within three years. The league aims to have 8 to 12 franchises at the Senior AAA level federated with Hockey Canada, which will compete for the Allan Cup representing Quebec. Within the five years the plan is have a league member host the Allan Cup tournament. 
Opening season PreparationsEdit
The league website originally listed four teams logos for the league's inaugural season of 2018-19, with plans to start the season with six teams. Plans are to play a 20 game schedule plus playoffs. The teams include the Fort-Coulonge Sr Comets (announced April 29th), Shawville Sr Pontiacs (announced May 1st), and the Cornwall Prowlers (announced May 8th)(to be based out of the Benson Centre) . The Maniwaki Forestiers were announced on June 8, 2018.
The Cumberland Sr. Bandits announced they would suspend operations on November 29, 2018.
After the first season the Cornwall Prowlers would leave the league for the newly formed Eastern Ontario Super A Hockey League. But no acknowledgement has appeared on the league website. In early August 2019 an expansion team was announced for Mont-Tremblant, Quebec which would play out of the Arena Gilles Cadieux. The team will be known as the Mont-Tremblant Diables.
