The 1989 Centennial Cup is the 19th Junior "A" 1989 ice hockey National Championship for the Canadian Junior A Hockey League.
The Centennial Cup was competed for by the winners of the Abbott Cup, Dudley Hewitt Cup, the Callaghan Cup, and a host city.
The tournament was hosted by the Summerside Western Capitals in the city of Summerside, Prince Edward Island.
The Thunder Bay Flyers were coached by Dave Siciliano, and won the United States Hockey League regular season and playoffs in 1989.[1] The Flyers began the Canadian playoffs undefeated in eight games with series victories versus the Sudbury Cubs and the Pembroke Lumber Kings to win the Dudley Hewitt Cup.[2] Siciliano recalled that the Flyers were not given respect in advance of the 1989 Centennial Cup, and said that "the host Summerside team commented at the coaches press conference that Thunder Bay couldn't be very strong since they played in an American-based league". During the round-robin stage of the tournament, the Flyers earned wins versus the Vernon Lakers and Moncton Hawks, and lost to the Summerside Western Capitals. The Flyers earned a berth in the cup finals based on goal difference among three teams tied for first place, then defeated Summerside by a 4–1 score in the final game to win the Centennial Cup. The Centennial Cup championship was the first for any team from Northwestern Ontario.
