How do I know the payout percentages advertised by an Ontario online casino are accurate and independently verified?

Skepticism about advertised RTP figures is entirely reasonable — and in Ontario's regulated market, that skepticism is exactly what the framework was built to address. Here's how the verification chain actually works, and what you can look for as a player.

Games must be certified before anyone plays them

Key components of igaming systems — including games and random number generators — must be certified against the AGCO's Registrar's Standards for Internet Gaming by a registered independent testing lab (ITL) before they can be deployed in the regulated Ontario market. This is not a voluntary step. Before applicable technologies can be deployed, operators must ensure games, random number generators, and components of igaming systems that accept, process, determine the outcome of, display, and log details about player bets have been certified — including slot games, table games, sport and event betting, poker, and other card games.

The ITLs doing this work aren't self-appointed. Certifications for Ontario's igaming market can only be issued by ITLs that are registered by the AGCO, and ITL certification provides the AGCO with reasonable assurance that the technology being tested complies with the relevant Standards. An ITL must also submit confirmation — such as an independent audit — that its own testing methodology has been configured to the Registrar's Standards for Internet Gaming before it can issue any certifications at all. So the labs themselves are audited.

What the Standards actually require operators to disclose

The player must be provided with accurate information to enable informed choices. For games that include progressive awards or game-within-a-game elements, the variable contribution of such awards to the theoretical payout percentage must be clearly disclosed. For games with different payout percentages for different betting options, the lowest theoretical payout percentage across all betting options must be disclosed as a minimum. That last point matters: when a game has side bets or optional wagers with worse odds, Ontario rules require the operator to show you the worst-case figure, not just the most flattering one.

If a game is modified after certification, those technologies must be recertified by a registered ITL when subsequent modifications are made that render the previous certification no longer valid, including modifications related to game integrity, fairness, and security.

The operator compliance layer on top

Within six months of commencing operations in the regulated Ontario market, all operators are required to submit an independently audited document setting out the processes and controls they have in place to meet all of the outcomes and requirements in the Registrar's Standards. This document — known as a Control Activity Matrix — covers the full operating environment, not just individual games.

The AGCO monitors igaming operators, suppliers, and digital game offerings for compliance with regulatory obligations, and where compliance concerns are identified, can bring operators and suppliers back into compliance through progressive sanctions, including warnings, suspensions, monetary penalties, and in the most serious cases, revocations.

How to confirm you're on a regulated site

None of this protection applies to offshore or unregistered sites, which is why playing on a regulated Ontario platform is the whole point. Every fully registered and approved Ontario igaming site displays both the iGaming Ontario logo and the BetGuard logo — per iGaming Ontario, seeing those logos confirms the site is managed by iGaming Ontario and regulated by the AGCO. A directory of all fully registered and authorized operators and their igaming sites is available via the iGaming Ontario website. That registry is the live source of truth if you want to verify a specific operator.

One practical note: RTP figures are theoretical long-run averages calculated over millions of spins or hands, not a guarantee of what you'll receive in a session. The certification process confirms the math behind those figures is sound — it doesn't change the fact that short-term results vary widely.
