The OSBA was unveiled in August, 2015 with eight participating schools: Mono Athlete Institute Prep; Markham Bill Crothers SS; Toronto BTB Prep Academy; Etobicoke Father Henry Carr CSS; Vaughan The Hill Academy; Breslau St. John’s Kilmarnock; Mississauga St. Marcellinus SS Spirit; and Mono Orangeville Prep. A month later, St. Marcellinus announced that they would not be joining the league as the coaches had neglected to obtain permission from the school’s administration.

Is Brantford TRC Academy and Rise Academy the same thing?

In its second year, the loop added Hamilton Lincoln Prep, St. Catharines Ridley College, Thornhill Thornlea SS, London Southwest Academy, Thornhill Vaughan SS and Oakville King’s Christian Collegiate, while losing Toronto BTB Prep Academy.

In 2018, additions included the Brantford RISE Prep Wolf Pack.

At the start of the 23-24 campaign, OSBA announced that the league was becoming unwieldy and scheduling too problematic to continue in its existing format. As an alternative, it would create two leagues to meet “market demand and satisfy the need to provide opportunities to keep our athletes in Canada. By offering 2 leagues, new programs that want to participate will have a way to transition into the OSBA and how to navigate being part of a scholastic league and the additional governance that is required compared to a house league or rep basketball league, or circuit. Any existing programs that would have been eliminated from the OSBA fully will be able to continue to provide opportunities for athletes. We want to be clear to our parents and stakeholders, this intent is not to ‘tier’ programs based on athletic talent. As a scholastic league that looks at the student-athlete experience as a holistic experience, all programs expressing interest in returning to the league were objectively evaluated based on Key Performance Indicators, on the academic side, and athletic side, as well as historical data within the OSBA. Based on coach votes for the “ideal” number of teams in the league, and the logistical challenge of scheduling more than 18 games, the leagues were assigned. … While programs will be evaluated annually, and there could potentially be team movement between the leagues, we plan to run 2 separate leagues for several years to satisfy market demand and allow us to partner with our programs to ensure they are meeting the standards of our governance model.”
