Ontario’s online poker model reaches Canada’s highest court on October 7, 2026. The Supreme Court of Canada will hear arguments in Atlantic Lottery Corporation et al. v. Attorney General of Ontario.

The case could decide whether Ontario’s regulated peer-to-peer games may share player pools with people outside the province or Canada.

The hearing will not change the market immediately. The later judgment could determine whether Ontario can pursue international and interprovincial liquidity for online poker and other peer-to-peer games.

  • The case is Supreme Court file 42141.
  • Ontario and Alberta support the broader liquidity model.
  • Atlantic Lottery, British Columbia Lottery Corporation, Manitoba Liquor and Lotteries Corporation, and Loto-Québec are challenging it.
  • Flutter Entertainment, NSUS Group and the Canadian Gaming Association will address the court as interveners.

What the court must decide

At the centre of the appeal is a question with direct consequences for players: can Ontario conduct and manage regulated peer-to-peer gaming when some opponents are outside the province or Canada?

Ontario wants the court to uphold a November 2025 decision by the Ontario Court of Appeal. The court ruled by a 4-1 majority that the Criminal Code does not require every player to be physically located in Ontario if the province retains control over the gaming activity offered to Ontario users.

A ruling for Ontario could support larger shared pools for online poker and daily fantasy sports. Larger pools can mean more frequent games, bigger tournaments and more competition between players.

The Supreme Court is not being asked to approve a new operator or announce an immediate launch.

Why Alberta is watching closely

Alberta is supporting Ontario’s position as an intervener. The province opened its commercial regulated iGaming market in July 2026, making it one of only two Canadian provinces with a commercial online market, alongside Ontario.

Alberta’s interest is direct. A ruling that permits pooled liquidity could create a legal route for Ontario and Alberta to connect some peer-to-peer games. Any such move would still depend on provincial decisions, agreements and regulatory requirements.

That possibility matters to operators active or seeking approval in both provinces. Flutter’s PokerStars and NSUS’s GGPoker are connected to the case, but their participation will not decide the appeal.

The Supreme Court’s counsel sheet lists Flutter, NSUS and the Canadian Gaming Association as interveners. Alberta appears separately as a provincial government intervener.

Four lottery corporations oppose the plan

Atlantic Lottery Corporation, British Columbia Lottery Corporation, Manitoba Liquor and Lotteries Corporation, and Loto-Québec are the appellants.

They argue that cross-border play could move Ontario beyond the Criminal Code’s provincial framework. Their position is consistent with the dissenting view from the Ontario Court of Appeal.

The appeal exposes a split among Canada’s regulated gaming bodies. Ontario’s iGaming conduct-and-manage entity is defending its model. The opposing parties are provincial lottery corporations that operate government-controlled gaming systems in their respective jurisdictions.

They are not one national regulator. The case will not create a single Canadian online-gambling licence.

What could change for players

If the Supreme Court upholds the Ontario Court of Appeal, iGaming Ontario could pursue a framework for international liquidity in peer-to-peer games.

Its 2026-2029 business plan says the proposed model could allow Ontario players to compete against players outside Canada. It also leaves room for interprovincial arrangements.

  • Larger player fields could become possible.
  • More games and tournaments could be available.
  • Ontario and Alberta could explore shared pools.
  • Regulatory, technical and jurisdictional agreements would still be required.

These outcomes are possible, not guaranteed. Any change would require further regulatory work, technical controls and agreements between the relevant jurisdictions.

A decision against Ontario could preserve the current province-focused structure. It could also force Ontario and Alberta to reassess how their newer commercial markets develop peer-to-peer products.

Why the ruling matters beyond poker

iGaming Ontario’s business plan describes stronger-than-expected performance in poker and continued growth across its regulated market. It identifies international liquidity as a factor in future market development.

That makes the appeal more than a dispute about tournament size. The judgment could shape how Canadian provinces interpret the Criminal Code when regulated online gaming crosses provincial or national borders.

The Supreme Court hearing is scheduled to last two hours and 40 minutes. The written judgment will come later. No ruling is expected from the hearing alone.
