SUMMARY:Ontario Open International Jiu-Jitsu Championships
DESCRIPTION:The Ontario Open International Jiu-Jitsu Championships (GI Edition) is the biggest and most prestigious tournament in Canada. All Jiu-Jitsu academies are welcome and invited to participate in the 2026 Ontario Open.With over 2,000 competitors competing in GI matches during our two-day tournament in May 2025 in Oshawa, it was very apparent that BJJ continues to grow each and every year. We had children as young as 5 competing and adults as old as 50 participating in the event. With competitors coming from all over Canada and US, the Ontario Open Jiu-Jitsu is an essential stop on everyone’s tournament schedule.THIS EVENT IS A PRE-REGISTRATION ONLY! This event will be GI ONLY. Divisions will be for all ages (starting at 4 years old), belts and weight classes. For more information on divisions, rules and registration, please visit the Ontario Jiu Jitsu Association website.
