The Gordon Renwick Cup is the trophy for the Senior "AAA" Central Canada ice hockey championship.

The winning of this trophy earns the champion the right to compete in the Allan Cup, the national Senior 'AAA' Championship.

The OHF champion is determined by the winner of the Allan Cup Hockey league in Southern Ontario.

The HNO championship is determined by playoffs amongst teams from larger towns in northwestern Ontario like Thunder Bay, Kenora, and Fort Frances.

[1] In some years, HNO has not submitted a champion or been given its own spot in the Allan Cup when another region has withdrawn.
