Registration Portal


OSS competitive teams will host their tryouts September 5th-15th at Ottawa U. Dates, and times for each age group will be circulated to registrants closer to September.

PLEASE NOTE: We encourage all players trying out for competitive to also register for House League as well so they are guaranteed a spot should they not be selected for the team. If a player is selected for a team, they will receive a 100% refund of their House League fees.

Players should do their best to be in attendance for ALL tryout dates if possible. If you cannot make a particular date, please let your coach know in advance.

All competitive teams have been formed for 2023-24.
