iGaming Regulations for Ontario Casinos in 2025

In April 2022, Ontario legalized online gambling and became the first Canadian province to develop its own legislation and regulatory structure. Now, operators based within the province must have a valid licence from the AGCO (Alcohol and Gaming Commission of Ontario) and regular testing from iGaming Ontario, AGCO’s iGaming branch. Online casinos must adhere to a strict set of regulations provided by AGCO in order to provide their services to Ontario-based players.

Who Can Use Ontario Casino Services Online?

Anyone who is 19 or older and located in Ontario can participate in Ontario online casinos. You do not have to be an Ontario resident.

What Documents Do Customers Need to Gamble at Ontario Casinos?

Ontario online casinos require their players to verify their identities in compliance with KYC (Know Your Customer) and AML (anti-money laundering) guidance. You may be asked to provide valid identification documents, such as a passport or driver’s licence, and proof of address.

How Is Geofencing Used at Ontario Online Casinos?

Many online Ontario casinos use geolocation to confirm their players are actually located within the province; they do this using GPS to ensure users can’t get around this using a VPN.

Ontario Casinos Player Protection Services

iGaming Ontario and AGCO work to ensure that all Ontario online casinos take the necessary steps to secure user data. They also strive to protect players by ensuring gambling sites only offer provably fair games and employ reasonable terms and conditions.

New Restrictions Within the Ontario iGaming Market

The new restrictions help to ensure all online Ontario casino operators are held to the same standards, but they also make it more difficult for Ontario-based gamblers to find offshore sites to play at. While this does have the effect of shrinking the market, it also allows unlawful websites to be filtered out more effectively. 

New Regulations Affecting Ontario Sports Betting

Prior to the legalization of online betting in 2022, Ontario-based gamblers could only bet on sports at offshore websites. Now, they can wager anytime from their phones or computers at reputable, properly regulated websites, thereby benefiting from rigorous player protection.

Top Payment Solutions at Ontario Online Casinos

Currently, Ontario online casinos offer a wide range of payment methods; we’ve summarized some of the most popular ones in the table below:

When trying to choose a payment method, we recommend doing plenty of research to determine which is the right fit for you.

Regulated Casinos vs. Offshore Casinos

There are lots of AGCO-regulated Ontario online casinos for you to choose from, but you may be considering some offshore sites to broaden your horizons. While this is perfectly legal, it is worth noting that you will have less legal protection at offshore casinos than at regulated ones. However, many reputable offshore casinos are licensed by well-known and respected regulatory bodies such as the Malta Gaming Authority (MGA) or the UK Gambling Commission. 

Оffshore casinos can sometimes offer a more flexible gaming experience, with fewer restrictions on certain payment methods or bet limits. While regulators from other jurisdictions may have less stringent licensing requirements than the AGCO, many of these websites maintain high standards for fairness, security, and responsible gaming.

Ontario Online Casinos Ranking Criteria

When rating online casinos, we take a wide range of factors into consideration, such as:

• Licensing and security. Your safety should always come first, so we only recommend websites that have valid licensing and all the necessary security measures.
• Variety of games. We prioritize Ontario casino sites with more varied game selections so that you’ll have plenty of options to choose from, including slots, table games, live games, and more.
• Bonuses and promotions. We recommend casinos that provide both new and existing players plenty of opportunities to win rewards and claim exciting incentives.
• User experience. When reviewing an Ontario casino site, we check out user ratings and test mobile optimization to ensure you are guaranteed a positive experience.
• Customer assistance. A solid customer support service is essential for any online casino; we assess the quality of available customer assistance on your behalf.
• Variety of payment options. We recommend websites that allow users to choose from a selection of different transaction methods, allowing them to use the one that suits them best.
• CAD availability. When putting together our Ontario casino recommendations, we highlight those where you can make transactions using CAD, as this is a great benefit for all Canadian players.

By considering these various criteria, we can give a balanced view of any online casino, one that takes the whole picture into account. When doing your own research into gambling websites, we urge you to keep them in mind as benchmarks of reliability and quality.
