Welcome to the home of Ontario Jiu-Jitsu. Jiu-Jitsu continues to grow in Ontario and Canada and the Ontario Jiu-Jitsu association is growing alongside.
Our membership continues to provide insight into the direction we should be growing and our Board of Directors continues to work tirelessly to bring the high quality events and competitions all members of the OJA have come to expect.
Please explore our website. If you decide Ontario Jiu-Jitsu is right for you and/or your club, we encourage you to Join the association today.
ALL Events sanctioned by OJA will be feature on our events tab.
