The 2026 Ontario Open is scheduled to take place from May 15 to May 18 at 901 King Street West in Toronto. This premier chess event is currently nearing its capacity, with 269 participants already registered out of a maximum 300 slots.
The competition consists of a seven-round Swiss format divided into several sections: Crown, U2200, U2000, U1800, U1600, and U1300. All sections are CFC-rated, while the Crown, U2200, and U2000 sections also carry FIDE ratings.
The time control is classical, 90 minutes plus a 30-second increment. Crown eligibility requires a minimum rating of 2200 CFC or 2000 FIDE.
The event features a $7,500 prize fund, with a guaranteed $1,500 for first place in the Crown section. In addition to cash awards, top non-member finishers in each section will receive a six-month membership to the Annex Chess Club.
The 2026 Ontario Open is organized by the Annex Chess Club. Registration is mandatory and must be completed in advance, as no onsite registration is permitted for this event. Professional titleholders, including GMs, IMs, WGMs, and WIMs, are eligible for free entry upon request.
