Club registration is the first step in the new H2O registration process as the registration of individuals affiliated with your club including athletes and coaches cannot begin until the club is successfully registered on H2OReg.


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.

The attached Registration Guide provides detailed information needed for 2023-24 club registration including steps on how to navigate H2OReg starting on page 11.

We encourage you to review the list of information required to complete the club registration application and to have this information available prior to logging-in to the H2OReg system. Once all the required items have been compiled in one place, we anticipate the online club registration process to take less than an hour. 

The deadline for club registration is August 4th, 2023.
