What does it mean for an online casino to be audited and how often does it happen?

Auditing is one of those terms that gets thrown around a lot in online casino marketing, but it actually describes something concrete and consequential — especially in Ontario's regulated market. There are really two distinct layers to it: technical auditing of the games themselves, and compliance auditing of the operator's entire control environment.

What gets audited — and by whom

At the game level, the focus is on the Random Number Generator (RNG) — the software engine that determines every spin, card draw, and dice roll. Without auditing by independent, third-party testers, RNGs may not provide assurance to players that random number generation is fair. In Ontario, this isn't left to operators to arrange voluntarily. The AGCO, through its Technical and Laboratory Services Branch (the "Gaming Lab"), is responsible for ensuring the integrity, security, fairness, and audit capability of all electronic gaming hardware, software, associated equipment, and gaming systems. The methods are rigorous: the Gaming Lab's work includes mathematical simulations and verification of game designs, including theoretical payback and award odds, as well as statistical analysis of datasets with millions of data points to verify the randomness of both physical and virtual RNGs. This work is performed by a team of experts in an in-house lab accredited to ISO 17025:2017, the international benchmark for excellence in testing laboratories.

Beyond the games themselves, operators must also demonstrate that their entire compliance framework holds up. All registered internet gaming operators are required to submit an independently audited assessment of the processes and controls they have in place to meet the Registrar's Standards for Internet Gaming — the AGCO typically refers to this as a Control Activity Matrix, or CAM. The independently audited CAM must include all controls related to the gaming site, including where the operator works with third-party suppliers such as platform providers. To meet the independent audit requirement, operators may use their internal audit function, where available, or external auditors.

When auditing happens — and how often

Auditing isn't a one-time gate that operators pass through and forget. The timing is structured around risk. Operators assessed during the AGCO's eligibility review as potentially posing elevated risk may be required to submit the independently audited CAM before they launch in the regulated Ontario igaming scheme. Operators that do not pose an elevated risk are required to submit their CAM within three months of their go-live date in the Ontario market. Within six months of commencing operations, all operators are required to provide a demonstration of the controls they have established to address the outcomes and requirements in the Registrar's Standards for igaming.

The regulatory framework is also explicitly designed to evolve. In order to keep the highest standards of integrity, periodic risk assessments will be conducted to ensure that the standards continue to be relevant. In response to identified risks and for compliance purposes, the AGCO may at any time request a CAM. So while there are defined submission windows, the AGCO retains the authority to audit on demand — it's an ongoing relationship, not a periodic checkbox.

What this means for players in Ontario

For anyone playing at a regulated Ontario site, this audit infrastructure is the practical reason why the games can be trusted to behave as advertised. The RTP (return-to-player) figure attached to a slot or table game isn't just a number an operator invented — it has been mathematically verified against the game's actual design. An important factor in Ontario's public confidence in gaming is the integrity and fairness of the games and gaming systems in play.

The simplest way to confirm you're on a properly registered site is to look for both the iGaming Ontario logo and the BetGuard logo — iGaming Ontario has confirmed that regulated operators display both. If those aren't present, that's a meaningful red flag. The audit trail and technical standards described above only apply to operators inside the regulated market; sites operating outside it carry none of these protections.
