The modern CJHL is governed by the by-laws of the Minor Hockey Association of Calgary which stipulates that each of Calgary's four community hockey associations operate at least one team. Presently, each association operates two teams that play a 35 game season. In the past, teams from the Calgary area have also participated in the league. Both the Okotoks Oilers and the High River Flyers of the Heritage Junior B Hockey League were originally members of the CJHL.
The CJHL gained national attention in October 2006 following a violent brawl which occurred in the hallway of a Calgary arena following a game between the NWCAA Bruins and the NEAA Canucks. A linesman attempting to break up an off ice scuffle NOT involving the NWCAA Bruins was allegedly knocked unconscious by a kick to the head in the melee which involved players, coaches and fans/parents.  As a result of a police investigation, Robert Simard, 21, of Calgary was charged with one count of assault for allegedly kicking linesman Rory McCuaig in the head. Simard and one other player involved in the brawl were given two year suspensions from playing in the league, ending their junior careers, and carrying over to any league sanctioned by Hockey Alberta. One parent was given a ban from all Hockey Calgary sanctioned arenas.
