What "regulated" actually means in Ontario
Ontario is the only Canadian province that has opened its online gambling market to competing, privately licensed operators under direct government oversight. That single fact is why this page exists separately from the rest of this site — everywhere else in Canada, "which casino is legal" has one answer (the provincial lottery corporation's own site) and everything else operates offshore. In Ontario, the answer is more specific, and worth understanding before you pick where to play.
Before April 2022: a single-operator market
Ontario players used to be in the same position as everyone else in Canada: the only made-in-Ontario option was OLG's own platform, PlayOLG, live since 2010, and every other real-money casino serving Ontario residents was licensed offshore, typically out of Malta, Curaçao, or Kahnawake. There was no private competition and no provincial registration process for online casino operators. By the province's own estimate, roughly 70% of the online gambling Ontario residents were actually doing before the market opened was happening on those unregulated offshore sites rather than through PlayOLG — the grey market wasn't a marginal problem, it made up most of the activity.
Why 2022, and not sooner
The province signaled its intent years before the market actually opened. Ontario's 2019 budget committed to building what it called a competitive and sustainable market for online gaming, aimed specifically at pulling the money residents were already spending offshore into a regulated, taxed channel — the government's own figure at the time put that offshore spending at roughly $500 million a year. What the province didn't yet have was a federal green light for single-event sports betting, and the plan was for a competitive igaming market and a competitive sports betting market to launch together rather than separately. That piece fell into place when Bill C-218, the Safe and Regulated Sports Betting Act, received Royal Assent on June 29, 2021 and came into force on August 27, 2021, removing the old Criminal Code prohibition on betting the outcome of a single sporting event. With that federal barrier gone, Ontario had what it needed, and the regulated market launched on April 4, 2022 — just under three years after the province first announced the plan.
The regulator: AGCO
The Alcohol and Gaming Commission of Ontario has regulated the province's alcohol, gaming, horse racing, and more recently private cannabis retail sectors since it was established in February 1998. Its authority over casinos comes from the Gaming Control Act, 1992 and Regulation 78/12 — when Ontario decided to open a competitive online market, it extended AGCO's existing mandate to internet gaming rather than standing up a brand-new agency, which is why AGCO's name sits on every registered operator's compliance file instead of some specialized new body.
The market operator: iGaming Ontario (iGO)
iGaming Ontario was created in July 2021, and its job has always been different from AGCO's: where AGCO registers and enforces, iGO conducts and manages the commercial side of the market — signing the operating agreements that let a private company legally take bets from Ontario residents, reconciling gaming revenue, and running the market's day-to-day responsible-gambling and anti-money-laundering programs. An operator needs both pieces before it can go live: an AGCO registration confirming it meets the regulatory bar, and a signed operating agreement with iGO covering the commercial terms. Neither one by itself is enough.
A structural change in 2025: iGO stops being an AGCO subsidiary
For its first four years, iGO was legally a subsidiary of AGCO — a lottery subsidiary corporation, on paper part of the same organization it worked alongside. That changed on May 12, 2025, when the iGaming Ontario Act, which had received Royal Assent the previous November, came into force and made iGO an independent agency in its own right. Oversight also moved ministries, from the Attorney General to the Ministry of Tourism, Culture and Gaming — the same ministry that already oversees OLG. The province framed the split as addressing a conflict-of-interest concern the Auditor General had raised about iGO answering to the body that also regulates it; AGCO still registers operators and sets the standards, but iGO is no longer organizationally underneath it. It's a detail most casino comparison pages skip, but it's the most significant change to how Ontario's market is actually structured since it opened.
What this actually opened up
Since April 2022, a competitive multi-operator market has run alongside, not instead of, OLG's own PlayOLG platform. Private brands have entered the Ontario market under this framework over time, each one going through the same registration and operating-agreement process rather than relying on an offshore licence the way the rest of Canada's market still does. That's the practical difference this page is about: a checkable, provincially enforced registration status instead of a licence issued somewhere else with no direct Ontario oversight.
