Rules and Regulations

Changes & Points of Emphasis for 2018–19 Season

1. Insurance
In order for games to be covered under Ontario Basketball (OBA) insurance, a team must be completely registered (including payment of all registration fees) with Ontario Basketball prior to their first game of the season and be in compliance with all insurance conditions.

2. Minimum Number of Players on Roster and to Start a Game

U13 Bantam to U19 Junior10155

Note: U10 Novice to U12 Major Atom teams that are able to demonstrate that they have made reasonable efforts to recruit 11 players for their OBA team roster but have been unable to do so may request an exemption.

3. Forfeiture Rules
For all U10 Novice to U12 Major Atom exhibition, sanctioned tournament, and OBL games, a team must have 10 players to start each game, otherwise the game is forfeit (2-0). In such circumstances, the game must still be played.

For all U10 Novice to U12 Major Atom Ontario Basketball Championships, a team must have 10 players to start their first game of the weekend.

4. OSBA Players Playing Club Basketball
Teams that have Ontario Scholastic Basketball Association (OSBA) players on their club rosters must declare their registration to Ontario Basketball via e-mail to Mike Barbin.

5. Team Jerseys
Teams must be wearing a jersey that corresponds to the affiliated member club that they are associated with. Sanctions for both the team and club will occur if violation of this rule occurs.

6. Exhibition Games: Sanctioning Process
Exhibition games must be reported and sanctioned by Ontario Basketball in order for game results to count for rankings, but more importantly for Ontario Basketball insurance to be valid. The new process to apply for sanctioning will be available on the Ontario Basketball website under Host an Exhibition Game.

7. Exhibition Games: Results 
Teams must post their scores within 14 days following completion of a game. If a game result is not posted within the above timeframe, the score will not be considered by the Ranking Committee.

8. Guaranteed Games and Tournament Format at Ontario Basketball Championships
With the new championship model, the breakdown for guaranteed games and tournament format for Ontario Basketball Championships is as follows:

  • Provincial Championships: 3 guaranteed pool games (1 game Friday and 2 games Saturday). Sunday will have semi-finals crossover to determine teams for bronze and gold medal games.
  • Ontario Cup Championships: 4 guaranteed games (based on an 8-team draw); same format as 2018 Ontario Cup Championships.
