PokerStars ONCOOP Returns to Ontario with $2M in Guarantees


The Ontario Championship of Online Poker (ONCOOP) — the flagship annual series of PokerStars ON — has returned for its fourth edition. Running from September 12 to September 29, the series is exclusively available to Ontario online poker players and guarantees C$2 million in prize money. It stands as one of the largest tournament series in the regulated Canada online poker market.

This series is the regional equivalent of the World Championship of Online Poker (WCOOP), one of the most prestigious annual tournament festivals in the global online poker market. The series includes 99 tournaments, with 27 designated as Championship events. Buy-ins range from C$20 to C$2,500. The Main Event, with a C$175,000 guarantee, is the centerpiece of the festival.

PokerStars has only announced a COOP series for Ontario and not for the United States. The series features multiple Main Events, including the C$50 COOP Mini Main Event, the C$300 COOP Main Event — Medium, and the C$2,500 High Roller Main Event. The schedule includes various formats and poker variants, such as 8-Game, H.O.R.S.E, Omaha variants, traditional freezeouts, progressive knockouts, total knockout formats, and mystery bounty tournaments.

I've spent years at the tables — cash and tournaments — and just as long shaping poker copy behind the scenes: room reviews, bonus fine print, tournament notes. At PokerInsider I write the way I wish more sites would: clear structure, honest trade-offs, no hype. Whether you're new or already grinding, I care about what the offer actually costs you — rake, variance, and the fine print — and I treat responsible play as part of the job, not a footnote.
