Twenty teams completed a 72-game season.
The defending champion Kelowna Rockets won their second consecutive Scotty Munro Memorial Trophy for the best regular season record; however, they failed to defend their playoff title as the Medicine Hat Tigers won the President's Cup, their fourth in team history, defeating the expansion Everett Silvertips in the championship series.
This gave Medicine Hat a berth in the 2004 Memorial Cup tournament, which, because it was hosted by Kelowna, also featured the Rockets, who went on to win the tournament.
