Weigh-in with ATTIRE ON. For Gi divisions, GI ON (belt included). For NoGI, rashguard and shorts (or legging for women).

If you are competiting in GI and NOGI, you will only need to make weigh for GI. HOWEVER, you still need to show up for weigh-ins when competing in NOGI as we need to check your attire.

1 lb allowance

All weigh-ins for the Ontario Open will take place right before each competitor’s first match or right after your division is called.

IMPORTANT! Each competitor only gets ONE CHANCE to make weight for their division, so please double check your registration before you hit the submit button to be sure you signed up for the correct division. Also, you will have an opportunity to check your registration information on your Smoothcomp profile or competitor list.

You have until Registration Checkday (Athlete correction) deadline Tuesday July 25th 2023 to make any changes to your registration. 


COMPETITORS 4 to 15 years old: NO DISQUALIFICATION. Your division will be adjusted after you weigh-ins if necessary.
