Ontario online poker future is in limbo, and so are the players.

The Supreme Court of Canada has heard arguments about whether Ontario can open its regulated online poker market to international players.

The Ontario Court of Appeal ruled in favor of shared liquidity last year, but the decision was quickly appealed by several provincial lottery corporations who are not as keen on international competition.

Ontario’s market has been ring-fenced since its launch, and operators are hoping a positive result will mean bigger tournaments and prize pools.
