Their logo is an ocean liner with a set of teeth on the bow, jutting out of waves. The team colours are royal blue, navy blue, and white. Their home arena is the Colisée de Rimouski. The team's sweater has proven popular in the USA, as Reebok has issued it with Sidney Crosby's number 87 on it.
The team is currently one of the more well-known teams in the Canadian Hockey League, particularly because of the addition of Sidney Crosby in the 2003–2004 season. Crosby's 135 points for the club set a new record for a 16-year-old in the QMJHL and was second only to Wayne Gretzky in that particular age-group for all Canadian Hockey.
In 2005, the Océanic set a QMJHL record, going 28 consecutive games without a loss. The team then went on to win 7 games in a row in the playoffs, improving the unbeaten streak to an unofficial 35 straight. They won their second QMJHL championship in five years, and represented the QMJHL in the 2005 Memorial Cup. After losing the opener against the hometown London Knights, the Oceanic beat both the defending Memorial Cup champions Kelowna Rockets, who were in their third straight Memorial Cup, and the Ottawa 67's. Rimouski then beat the 67's again in the semi-finals to set up a rematch of their opening game against the Knights. The Oceanic were shut out in the final game 4-0.
The QMJHL announced on April 3, 2008, that the Océanic were chosen to host the 2009 Memorial Cup.
