This is the 2017-18 Calgary Junior Hockey League season. This is the league's 73rd season.
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. Due to the close proximity of the member teams the eight teams use four rinks for their games: the Max Bell Centre Calgary (rinks 1 & 2), the Stu Peppard Arena, and the Rose Kohn Arena.
All eight teams qualify for the playoffs. The teams are re-seeded after the quarterfinals with the winners being re-seeded as #1, #2, #3 and #4 based on regular season record. With the exception of the best-of-five final all series are first team to at least 3 points wins the series (ties are allowed in the playoffs). The playoff champion advances to the 2018 Russ Barnes Trophy (Alberta Junior B championship) being held in Fort St. John, British Columbia The winner of that tournament earns the right to participate in the 2018 Keystone Cup which was held in Thunder Bay, Ontario. However, during the 2017 off season both representatives (the three BC based leagues themselves as Hockey BC does not mandate participating in regional and national events) and governing body (Hockey Alberta) announced that the teams would no longer participate in the event. For some reason the CBHA Rangers declined to participate in the 2018 Russ Barnes Trophy tournament and the CRAA Gold participated in their place.
