Potter led initiatives to organize the Northern Alberta Intermediate Hockey League in 1948, and became secretary of the Western Canada intermediate hockey committee to organize inter-provincial playoffs. Intermediate hockey teams in Alberta included the Edmonton Mercurys who won the 1950 Ice Hockey World Championships, and the Lethbridge Maple Leafs who won the 1951 Ice Hockey World Championships. Potter chaired the committee that organized the victory parade in Edmonton for the Mercurys. Alberta had been without top-tier senior hockey since 1950, after its two Western Canada Senior Hockey League teams joined the Alexander Cup Major Series, then became professional. Potter blamed the increase of minor league professional hockey for the decline the senior hockey in Alberta. In October 1951, he and the AAHA upgraded the intermediate teams to A-level and B-level senior teams, which allowed the A-level teams to compete in the national Allan Cup playoffs.
