Ontario Championships 2023: Event info, draws & results available here.


As of July 2022, OAS has launched its new H2OReg club registration system. This new system streamlines annual club registration, providing a better and more efficient process, reducing the administrative burden on clubs, and improving overall compliance with CAS and OAS policies.

All queries related to registration and the H2O registration process should be directed to Sue Marnica-Wall.


All individuals participating in sanctioned artistic swimming programs or activity (virtual or in-person) on or after September 1 must be registered on H2OReg. This ensures they are insured to take part in any artistic swimming activity. Officials must register themselves, pay their applicable OAS and CAS fees via the online H2O registration process, and have an ISSUED status on H2OReg by the deadline of September 30, 2022 to be insured and eligible to participate.

The attached Registration Guide provides detailed information needed for 2022-23 officials registration, including steps on how to navigate H2OReg.
